Supra FAQ page 3
I want to have a
fast 4th gen Supra, for as cheap as possible. Can I just buy a high mileage Non-Turbo model and convert it to a Turbo? To convert an "NA" Supra to a full Twin Turbo spec Supra would require a lot of money, a lot of time, and a lot of
headache. The Twin Turbo is more than a NA Supra with two turbos bolted to the cylinder head. The entire drivetrain is different,
as well as the brakes, electronics, wiring harness, etc. Most non-Turbos sell for more than $15,000. The cost to convert it
to a twin turbo is more than $10,000 for the used parts alone. This would be an unwise route to go as early Twin Turbos can
be found for a little over $20,000.
The other option is installing a Turbo Kit specifically designed for the NA on
a non-turbo Supra (kits for twin turbos will not bolt on an NA). This is an easier route, but it can still get expensive,
and the NA is not capable of NEARLY as much power as a modded TT.
The wisest thing you could do would be to save your
money for a Twin Turbo model, it will cost much less in the end, and your resale will be higher.
I
can only find Automatic equipped Supras for sale, can I buy an auto and just convert it to manual? This is not
a bolt-in swap. To do this swap you would need the Transmission, Shifter, Clutch Master Cylinder and accessories, flywheel,
pressure plate, clutch, ECU, Pedal Assembly, Driveshaft, Rear Differential, Wiring Harness, Rear Axles, and the transmission
tunnel requires modification. Most shops charge around $7,000 to do this swap with USED parts. Use of new parts pushes this
up MUCH higher. Keep in mind the Getrag transmission costs $5,000-$6,000 new. This is only a logical swap if you already have
an Automatic Supra with a significant investment in it.
What should I buy, a Single Turbo
Supra, or a Twin Turbo Supra? Two types of 4th generation Supras were sold, non-Turbos and Twin-Turbos. The Single-Turbo
Supras you see are cars that have had the two small stock turbos removed, and a huge high-power single turbo put in its place.
Basically they are modified.
Why are used Supras so expensive? Supply and demand.
The Supply of Supras is very low, and demand is pretty high.
Why are people trying to rip
others off by selling their Supras for more than Blue Book Value? They aren’t ripping anyone off. This is
a capitalist’s society. Supply and demand rule the fair market price, not a book. Also, those books don’t set
the fair price, they reflect it. And they don’t take into consideration the private sales, only dealer sales. Most Supras
are sold privately. Also, if you were selling your car, you would try to get as much as you thought you could!
Can I just buy a salvaged non-Turbo Supra and fix it up and make it a Twin Turbo, and save a fortune? For
one thing, if you think finding a Supra TT is hard, try to find one at a salvage yard. Because of the Supras high value, they
don’t get scrapped. But if you find one, the demand for them is so high, they sell for a lot of money ($7k-$11k for
a N/A). Then the cost to convert a N/A to a full TT is more than $10,000 for used parts alone. And then a ton of work will
be needed. And don’t forget about the cost of restoring the salvaged car, as well as the fact that it will have a salvage
title, and resale will be low. The notion of building up a salvaged Supra is the result of a certain movie. In real life it’s
not that simple.
What should I check when looking at a Supra to buy? -Have
someone cold start the car while you stand behind it watching the tailpipe, and look for gray smoke with a blue-ish tint (easiest
to see in direct sunlight)
-Let the car warm up and continue to stand behind the car checking for smoke
-Now
move to the front of the car, and open the hood. Listen for bad noises (Noticeable Injector Ticking is Normal)
-Now
go back and watch the tailpipe for smoke, have someone blip the throttle, while you watch for smoke, let it idle between the
blips
-Now do the same but have them mash the gas and rev it up till like 5000rpm or so
-Now have a friend follow
behind you in another car while you go for a test drive
-Have him watch for smoke while you drive
-Put it in
2nd gear, let the rpm drop to about 1500, and then stomp on it, and stay on it till redline, then let off the gas. Your friend
should be watching for "gray/blue smoke". Just grey/black smoke is ok.
-Smoke at cold start-up, leaving a stop-light,
or throttle blipping from idle is valve stem seals. Smoke under boost, or after letting off of boost, or maybe when revving
full throttle, is turbo seals. Smoking for no good reason, or if it doesn't stop pretty quickly is piston rings (may get better
or worse when hot).
-Your job while at full throttle in 2nd is making sure the turbos boost fine (smoothly), that you
can feel full boost by 4500rpm or near it, and that you don't hear bad noises (slight turbo whistle/whine is ok, if it has
an intake it will be noticeable)
-Use all the gears in the transmission, and make sure it shifts fine (if it is a 6spd,
it is going to feel and sound clunky too you, that’s normal. If the transmission makes "ball bearings in a can" sounds
at idle or low speeds, that is 2-piece sprung flywheel and is normal)
-While driving with the windows down, listen
for clicking or popping noises coming from outside the car. (A POP when starting or stopping, or making a sharp low speed
turn (maybe up a hill), is the drivers side engine mount. A clicking sound under initial mild acceleration or deceleration,
that lasts for only a second or two then stops, and sounds exactly the same regardless of speed, is the rear upper control
arm bushings. A clicking that changes with speed is wheel bearings)
-Make sure the brakes work smoothly and reasonably
quietly. When coming to a stop take your hand slightly off the wheel and make sure it stays straight.
-Make sure the
car tracks straight on flat roads.
-A creaking noise from the hatch when turning up hill, means it needs rubber hatch
bumpers.
-Rattling from above you means the targa is loose (make sure the targa bolts loosen, and tighten back down
smoothly) and make sure the targa wrench is there.
-Make sure the rear hatch opens and closes fine, and that is stays
up on it own.
-Make sure all the doors open and close smoothly
-If you can really smell the exhaust when coming
to a stop, it has no cats
-If when flooring it, the car pulls smoothly till ~4000rpm, and then rockets forward like
getting hit with a semi, then it's BPU and not stock. If you can hardly feel a change over from the 1st turbo to both, then
it's stock.
-When checking under the car for leaks, don’t be alarmed by an oily sludge on the transmission and
differential. That’s a greasy undercoating that Toyota applied. But check for fresh oil leaks, and check the rear CV
joint boots for cracks.
-If possible, look at the spot where the car normally parks. Check for fresh oil puddles or
spots. If they say their other car caused the spot, don't believe them if it's a clean 1-2 year old car they are blaming it
on.
-Check the wheel rim, inside and out, for curb rash or bent rims.
-Check for excessive or uneven wear on
the tires
-Check for cheap, or miss-matched tires
-Look to see if all the little plastic panels and parts under
the car all line-up, and are attached, and that paint is not where it shouldn't be (cracked under trays are not uncommon,
don't be alarmed). Spend a fair amount of time on the ground, don't be afraid to get a little dirty. Also all the major body
panels have the original VIN number visibly stuck on them, make sure they are all still there and are the right number. Look
for missing, non-original, or out of place fasteners. All these things are possible signs off a collision.
-Check for
signs of rust in the wheel wells and inner fender
-Check the condition of all the exposed rubber on the suspension
joints
-Make sure the power steering is smooth and quiet
-Make sure the gaps in the body panels are all even.
-Walk
all around the car, and look at each panel at different angles. Looks for small dents and dings, and make sure the paint matches
all around.
-Look over the paint condition very closely
-Check around all the glass to see if it has been replaced.
Check the manufacturer information on the glass to see if they are all the same.
-Make sure all the exterior lights
work
-Check the headlamps for cracks, moisture or fogging/yellowing (expect them too be fogged/yellowed if an earlier
model)
-Make sure to test every last switch in the car to make sure it works (power windows, locks, turn signals, light
switch, dome lights, power seat, cruise control, everything). Use all the functions on the A/C and make sure they all work.
Go from HOT to COLD A/C and make sure it's getting very hot, and very cold. If it has a factory alarm, make sure the key-fobs
work.
-Check the interior for excessive wear (cracked leather in the seat's side bolsters is pretty damn common).
-Check
all of the fluids, make sure the fluid isn't terrible. Open the oil fill cap, and look inside for sludge build-up (you shouldn't
see any)
-Find out what oil the use, and how often (don't trust their answer unless they have receipts)
-Ask
them if they have had any work done to it. If they have owned it for several years, and say they have done nothing to it,
don't take that as being a completely good thing.
-Ask if it has ever had modifications, and what.
-Make sure
it still has the spare tire, jack and wrenches, owners manual, and targa wrench.
-Try to get the repair records
-Do
a Carfax.com check on the VIN #
-Take it to a mechanic you trust AFTER you have done all this to get it checked out
one last time before buying it.
-If the owner refuses any of this, be suspicious.
-Try to take a level-headed
friend with you who you can trust.
This may sound like a lot to do, but really it's not, most of these things take
no more than a second to do. Make sure to always go look at a car on a bright sunny day, and make sure you and the seller
will have plenty of time (don't rush anything)
Any problems you find (and your likely to find a few) should not mean
you shouldn't buy the car. But you need to know what you are getting into, and whether the price is reasonable. Always negotiate.
People are almost always willing to come down some on their asking price. And be prepared to walk away as hard as it may be.
