A What to look for Guide on buying used MR2's


Introduction

So...you've been looking around for or at a used MR2! The MR2 is a wonderful sports car without a doubt, but you must look out for a few things. This page will point out a majority of problems I have had, and know of with used Toyota MR2's. There are two sections below, one for the Mark II ('91-95 in USA) and the Mark I ('85-89). Yes America did not receive any '90 MR2s out there...If a U.S. dealer/person claims it to be as such..they are throwing you a bogus year. The 1990 MR2s were, however shipped to other countries, most of the 1990's seem to be in New Zealand!! If you know of any usual problems that I've left off, please let me know. Some of these pertain to many other cars also. Additionally both Generation MR2s have Yamaha Heads (4A-G(Z)E & 3S-GTE, maybe 5S-FE) and Toyota blocks, that can last well into 200K miles with regular care.

'85-89 Mark I MR2's

Updated-3/00

Ahhh, the Mark I MR2. A great way to enter the world of the MR2 at an affordable price! Fortunetly for you, there are many of them for sale, so you can be picky!! To start off, try and go for a 88-89. These models had suspension, brake, transmission, and other systems updated to improve past problems (like the front rotors warping on earlier models), or to just make the car even better. The interior of these is also improved, not to mention the 7-spkr stereo system was added. Don't get me wrong, there's nothing wrong with earlier models, they just tend to have more problem areas. My last suggestion is to find one that the owner garaged and cared for well, no one wants one that's been run hard and not properly maintained!!

Look for the following visually:
	
	-Look for rust around the whole car, especially the wheel wells, 
		Rust can/is a problem on these cars.
	-Look at rear of the car for sooty residue. This usually signifies a Ring 
		problem and loss of compression, this costs about 1600$(min) to have someone rebuild it. 
		A OILY residue could also signify worn Valve guides. If the car was cleaned it
		may be hard to tell, so look for this after you drive it!! 
	-Look underneath the car for any body damage from being bottomed out and the like. 
		Another good idea is to check for past wreck damage by looking for repainted areas
		or better yet take it to a place to check the integrity of the frame.  If your
		planning on doing some racing it's important to have a sound frame.
	-Look underneath the engine/transmission area for oil, &/or transmission fluid leaks,
		the oil cooler lines seem to go after years of use and the breather plug sometimes
		comes loose on the transmission case, allowing transmission fluid to leak. Both
		of these problems are expensive to fix. You have to buy or tap the transmission case
		to fix the breather.  If this problem exists you can usually smell it when it hits
		the rear exhaust and burns after driven, kinda weird smell on drivers side.
	-Be Wary of buying higher mileage MR2s that have not been run for 4+ months.  During that
		time hoses may have dried out, and once it starts to be really used again these can crack,
		break, and cause problems and grief.  (Low mileage is usually 50K-70K)
	-Look around the engine for worn vacuum tubes that should be replaced.
	-Look at the where the distributor attaches to the head (round thing with the spark plug
		cables come out of).  See if there is evidence of oil leaking.  The seals of these
		distributors tend to go, allowing oil from the head to seep into here and then out
		into the engine area.  This also reduces performance by interfering with rotor contacts.
	-Look in the front (under spare tire) compartment for rust, and see if the tools are 
		present, as in the spare tire, tire rod, jack, etc.
	-Check for signs that panels have been replaced and repainted. Sometimes panels get replaced,
		hiding past wreck damage. You can usually tell because there is no seem sealent, and or
		the paint color is different on the other side. I've found the front side panels to be
		replaced often on slightly wrecked MR2s.  It doesn't hurt to use CARFAX and find out
		if the vehicle had been damaged (only if claimed).
	-Look at the windsheild seals..make sure they are not cracked, and check inside for 
		evidence of water damage, or leakage.  This happens often on older vehicles that
		have the original seals.  You should also lift up the interior carpet to check for
		signs of rust, indicating a water leak.   T-Top MKIs start leaking around seals.
	-Look for damaged or bent rims.
	-Look at the engine compartment and check for fluid leaks, cracked hoses, fluid levels, 
		rust, etc.
	-The seats tend to have small rips, or tears by this time, especially the SHIFT BOOT. This
		is normal, and the shift boot can still be purchased by toyota for 50$ or so.  I know
		it makes the inside look crappy but it's an easy fix, don't let it deter you! You 
		might even use this to help reduce the sell price!!
	-If the car has T-Tops look for cracks around the body surrounding them..MR2s can develope
		cracks from hard driving/cornering and such disregard for physics.

Look for the following by Operating the vehicle:

	-Apply the brakes often and see if a vibration occurs, warped rotors happen often with 
		'85, '86 Mr2s ..Rotors are usually 45$ each. 87-89s have newer brake systems that
		doesn't seem to have near as many problems.  BE CAREFULL when torqueing down the wheels
		on MKIs...don't over torque them or the rotors WILL warp.
	-Pull up the parking brake and make sure it holds the car...frozen parking brake cables
		are a constant taunt and aren't cheap to fix, nor is it easy to repair. In the winter
		water that entered the brake cable through worn brake cable boots WILL freeze and lock
		your rear brakes, allowing you to go nowhere until thawed. This goes double for MKIIs! 
	-Go through all the switches, especially the headlight, and wiper dials...they can easily
		be broken or not work correctly due to design, and heavy use.  Check that all meters 
		are working, speedometer, etc..  If it has power locks and windows, be sure to test them
		also....window motors seem to wearing out more often on MkIs.
	-While driving, hold the vehicle straight on a flat & straight road and let go of the wheel
		(keep your hand near the wheel) and see if the car vears to one direction.  If it stays
		pretty much straight, you don't have any alignment problems, if it prefers a direction
		then you need to get it aligned. (Make sure the road is nice and flat too!!)
	-Turn on the stereo (if it has one) and make sure to turn the bass up to make sure the sub-
		woofer works properly.  I know plenty of MR2's who's subwoofer quit working or never 
		worked. The stereo system of 85-86(maybe 87s) only had a few speakers where 88-89 had
		the newer stereo setup.
	-Make sure the idle is smooth (keep in mind the MR2s idle higher than most cars.) and not
		bouncing up and down.  This can be a number of problems, but usually a vacuum leak.
	-In each gear accelerate quickly and slow down quickly.  This is to test the synchronizer 
		gears and linkeage on 5-spd manuals.  Many MR2s have problems staying in 5th gear. The
		later 88-89s toyota seems to have taken care of this.
	-Check the clutch by seeing how well the clutch engages, and how far up your foot has to
		come up before in does. (make sure it isn't slipping)  Many Supercharged MR2s I've 
		tested have worn out clutchs...this is not as much a problem on the NA models.
	-When Driving an SC, make sure the boost comes on smoothly and quickly.  That "jet engine"
		sound is normal *smirk*!! Full boost can be had in third & fourth gear.  
	-While the car is at rest but running...look under the engine area for leaks, and look at
		the exhaust for white/ blue smoke...these are pretty good indications of engine 
		condition as far as the head, exhaust, & compression, goes.  Blue smoke indicates blow
		by problems, and/or loss of compression, due to ring wear & deterioration.  Many '85-86
		Mr2s I've seen, start developing this around 110K-140K miles! This is from wear and tear
		on the engine. My own had a blow by problem.  After a 30 mile drive the back
		of the car would be covered with exhaust goo, and oil, both fresh and smoked!! Be
		carefull with this one...it's expensive to fix, and sometimes cheaper to just buy
		a new engine if you can't fix it yourself.  NOTE: If you're a big DIY you can get a car 
		cheaper if it needs engine work, IF your willing to take on re-building or replacing the
		engine and replace all the hoses and other cheap stuff while your at it.
	-While the car is running, place the parking brake on and the clutch in nuetral.  Wait a
		little bit and see if you hear a slight crunching sound in the transmission area.
		This is usually worn out clutch bearings, and is often a problem with earlier 2s.
	-While driving or idling, listen for any clicking/clacking from the top of the engine.  Older
		mileage cars, that haven't had their regular valve maintenence tend to get noisy. This
		costs a couple hundred from Toyota to do. If your a DIY it's actually pretty cheap, just
		needing a couple of special tools, shims, a dial gauge, and patience.
	-When in doubt get a fellow MR2 owner to test the car with you, and it never hurts to have
		the compression checked before you buy...
As a final note, be sure ask for any available records for work performed on the car. IE. When the timing belt was replaced, etc.


'91-95 USA Mark II MR2 Turbo

Updated-1/00


IT's HERE!!

Many have been asking me exactly how to check the turbo's condition on the MR2 Turbo....SO I created a webpage that is devoted to checking the various problems listed here, especially checking the turbo condition...and some turbo 101!!


How to check your turbo & Turbo 101

Sooo, you wanna sports car but don't have the cash? Well the second generation should fit you just fine, and your friends will be suprised when you tell them it only cost as much as their new & slow Dodge NEON! The '91 year is even more affordable now being in the 7-9k range. You'll be pleased to hear that the Normally Aspirated (NA) Version is probably the most reliable MR2 made, and you really have to search hard to find ones with problems (AKA Reliable Rocket). The "baby Ferrari" as the stronger brother with the turbo has been called, tends to take it's share of problems from wear and tear, and of course time. This is mainly due to the effects of an engine running aspiration (turbo or supercharger). Any labor needed on these engines will cost, so the DIY attitude will save yourself some cash. Keep in mind some of these pertain to the Turbo version and not the NA MR2.

   Look for the following visually:
	
	-Check to see if the rear exhaust tips have allot of carbon buildup. This will be a black sooty residue.  
		Some is Normal, as the MR2 naturally runs a little on the rich side.  This can signify that 
		the car is running too rich, caused by a failure or intermitent problem in any of these devices:  
		
		Bad or Intermittend Air Flow Meter (AFM)(600$ new 225$ used)[Mine went bad]
		Oxygen sensor (only when engine warmed up)
		cold start injector switch(your computer think the car is always cold and therefore runs rich)
		MAP sensor
		EFI Coolant Temp sensor
		BOV, VTV....
	
		It could also signify that the turbo is going, or gone bad, and is spitting oil into 
		the air intake system, forcing it to ingest oil, decreasing performance.
	-Check the engine compartment for leaks around the valve cover, transmission case, and 
		especially check for oil & such around the TURBO!!!  I can't stress this enough, my
		MR2 turbo had these indications and sure enough the turbo bearing seals were gone, 
		and the intake hoses/chambers had tons of oil puddles.  Not to mention it didn't run
		the boost levels it once did.  So be carefull, Toyota wants $2000 for this part!!! 
		Around 500$ to rebuild the one you have. An upgraded turbo can be 1k-2.5K$  Keep in
		mind that until the engine is fully warmed up will the ECU let the boost go above 6-7 psi.
		The stock Turbo MR2 will produce (typically) 9-11 PSI of boost.
	-Check the interior for signs of water damage due to a worn out window seal and such.
 	-Look in the wheel wells for worn out McPhearson strut boots (very common)!!
	-Look for dents / damage underneath the car. Have frame checked for integrity.
	-Check that the rotors are nice and clear, with plenty of pad left. Some MR2s have damaged
		rear rotors due to the parking brake freezing, and they drive it anyway! BAD BAD driver!!
	-Check all lights & windows for leaks/cracks, and make sure no fuses have been blown. If the
		USA mr2 has clear corner lenses, it's a normal JAPAN part mod.  Check my pictures for a look.
	-If the car has new tires, be sure to check alignment when driving, many dealers use new
		tires to cover up old alignment problems.
	-If the MR2 is a NA and it has hole areas in the front grill area, someone may have modified it with
		fog lights and then removed them.  
	-If any oddities arise, like modified components left on the vehicle, check their condition too. As these
		MR2s get cheaper and cheaper, people are doing more and more modifications. These can contain such 
		mods as:
			+Some form of Low restriction Intake filter. (HKS Superflow, K&N, Apex'i, etc)
			*WARNING: 	Vehicles with the HKS Superflow, can have foreign particle build up that
					hurts engine components.  This is because the filter does not do a good job
					at filtering dust/dirt and other particles. Several MR2 owners have found
					damaged engine bearings and such, down to the copper, because of the HKS
					and it's sucky dirt filtration.  I suggest the K&N.
			+Performance rims, lowering springs and other suspension pieces.
			+Turbo Boost Controllers (some electronic, others are manual adjust valves.)
			+Turbo Timer (actually a good sign) designed to let car idle after you leave to cool 
				down turbo
			+A NA MR2 with a 3S-GTE (turbo version) engine.  
			+Gauges - boost, fuel pressure and the like.
	-When doubt, get a fellow MR2 owner to come look with you.

  Check the following while operating:

	-Make sure the car idles fine, and does not stamper, stuter, and watch that the RPMs are 
		steady and smooth.  I have found many MR2s who have a bad Cold start injector switch
		(mine did) and caused the car RPM to be erratic, and cause the car to hesitate due 
		to richer fuel. The switch is about 103$!! 
	-While driving, when boost comes on listen to see if there is any fast clacking(clicking)
		sound from the engine.  This can be a bad Blow Off Valve. Which can cause hesitation.
	-If at any time, especially when cold the car bucks,and/or be limited on engine speed, and 
		stall when moving. YOU PROBABLY HAVE A BAD AFM.  This took me forever to diagnose, and
		because it was so intermittent and would usually go away once the car warms up, no
		one at Toyota or anywhere else could figure it out!! Since replacing mine the problem
		has totally dissappeared!  I've seen four Turbo MR2s with this problem! NAs don't need
		to worry. Also, some previous owner may have damaged their AFMs, by unscrewing the 
		connector instead of un-clipping it off! A REALLY bad AFM will trip the Engine light. A
		NA does not use a Air Flow Meter.
	-Test the the intake system for build-up (Throttle body & T-VIS system). You should feel a 
		difference under acceleration between 3500-4000RPM. If it feels hesitant in this area 
		you may have buildup problems affecting the T-VIS operation.  See if the throttle is sticky
		at first...it may need cleaning.  Higher mileage cars have more carbon & oil buildup, 
		especially turbos. Some can hear the change when T-VIS flaps open up, but it's not near
		as pronounced as any VVTL-i or VTEC system.
	-Make sure the parking brake works and is not frozen.  Meaning that with the brake released
		there are no signs that the rear calipers are still holding.  Same as on MKI MR2. The
		parking brake cable boots can be gone letting in water which can freeze the cable to it's 
		sheath, preventing the calipers from disengaging.  Replace the boots, and cable or dry
		the cable, and lube to solve this problem.
	-Check the usual lights, A/C, radio, gauges.  I found that the water temp gauge sending unit
		attched to the cooler lines tend to go out, thus leaving your gauge on Cold all the
		time. (Make sure all headlights come up, and fog lights on Turbos work)Some people have
		blown one channel of their stereo, letting one side work and not others.  Check the CD 
		player too, mine is now on the fritz!!
	-Make sure boost comes on smooth and quickly, without hesitation.  If the car hesitates,
		and is not smooth, then it could signify a wastegate/Turbo problem...Any turbo over 65-80K
		miles is due to be rebuilt or replaced...if your running a old turbo, chances are upper range
		HP is lower, falling off sooner, and producing less boost that one in proper condition. The 
		typical boost is between 8-11 PSI after warmed up.  If only the stock boost guage is available
		i have found that the first big tick is around 0 PSI, halfway up is 4psi and the next big tic is
		8psi, while nine is around the "+" sign.  Full boost is usually available in third & fourth gears
		in the mid-upper RPM range. Check my How to check the turbo pageor 
		e-mail me and I'll explain how to test the mechanical condition of the turbo.
	-My 91 Turbo has 151K miles and is going strong, but always go for a lower mileage car if you can.
As a final note, be sure ask for any available records for work performed on the car. IE. When the timing belt was replaced, etc
