getting power out of your supra

[BryanDyer]

whats the best way to start to get more hp and torque out of the supra without doing any major internal engine work

Maintenance, it'll have a noticeable gain.

I always like to start it up and as sooon as it starts hold the pedal to the floor for 30 seconds. This will clear most carbon build up and it should run like a champ afterward.

BryanDyer, he's kidding. And OfnaRcR4, put a fucking smiley or "jk" in there next time, kthx. Don't want a repeat of something like this: http://mustangforums.com/forum/5-0l-general-discussion/368307-im-done-with-this-car.html

@OP: Assuming that everything is in good to excellent condition already, and that your cooling system is tight and secure, with no build-up of junk between the A/C condenser and radiator, your head gasket is in good condition with head bolts re-torqued to 72 ft-lbs, or head gasket is replaced with ARP hardware holding down the head, and that you have good oil pressure, then the easiest way to get more power is to install a boost controller, and pump up the boost to ~10 PSI.

If you want to go further than that, you should learn more about how the car works, and what issues to look out for. Actually, you should do that before doing ANYTHING to the car.

Sorry i probably should have said just kidding or something. In all seriousness. Everyone else is right. Chances are your supra has been mistreated and ill maintained for the past decade so maintenance and a LOT of reading and learning will do you a ton of good. Not trying to offend but the fact that you ask a question like this shows you probably need to read up a bit more before doing anything to the car. We've all been there, i know i have

 

[BryanDyer]

well i just bought an 87 turbo and it only has 77xxx original miles with 1 owner and garage kept..so im not worried about it being mistreated or anything and its well maintained and i was thinking about starting with a boost contorller and exhaust

Since you seem to have no idea what you're doing how about you just enjoy driving that nice car stock for a while before blowing it up?

 

[BryanDyer]

i do know what im doing? im just asking for opinions..

 

[OfnaRcR4]

Keep in mind the car is 25 years old so all the parts/seals and such may be 25 years old. Doesn't matter if it doesn't have many miles or that it was garage kept. Don't mind the grumpies. We just see this all the time with new people. If you have to ask such basic questions though its probably not a good idea to go crazy with mods right off unless you are prepared to have someone else who knows what they're doing do major work on the car. These cars will drain your wallet quick if you don't know exactly what you're doing.

^Amen. The learning curve on these cars are not just emotionally and physicaly painful, but it will rape your wallet, bank account, credit card, and the change in your couch. Learn as much as you can (ie read the forums and other resources) before doing anything to the car. BTW sounds like a good find. Start with general maintenance - change all fluids, belts, hoses, check all brakes suspension, steering... this will give you a great intro to the car mechanicaly. Then go from there.

77K miles = just as neglected as the rest

they do that even if you do know what your doing .

do the basic maintnece first, brakes, suspension, check all hoses that they havnt turned into hockey puck rubber.

well im replacing the head gasket timing belt water pump etc...and im starting with basic mods like intake exhaust things like that but i was posting the thread just to find out what else i could do when i wanna upgrade the turbo down the road after i get used to driving and learn becuase this is the first one ive owned and ive noticed a lot of people like the 57 trim ct26...how is it?

 

[jonahs_supra]

1st of all Poodles is right 77k miles doesnt mean anything, rubber rots and hardens over time(which means a blown coolant line and then warped head)
i bought my 91 with 76k miles and garage kept. i replaced all common maintenance items before the jump into more power(fluids, belts, spark plugs, wires, hoses, brakes, brake lines, filters...etc)

once i new my car was running well enough to handle power i then started to modify

start with upgraded air filter, 3 in down pipe, 3in cat back exhaust, install a ELECTRIC boost controller(MBC tend to change psi with weather change), set boost to 10-12psi
if your not happy with that then proceed with more upgrades like a 57 trim ct
at 1 point you will need to address fuel cut and needing more fuel
youll need a way to pump more fuel into the engine...so higher flowing fuel pump(walbro 255 does nice), bigger injectors(common 550cc), adjustable fuel pressure regulator(driftmotion sells a kit)
with that said youll now need a way to control it and make fuel cut stop bitching...this is where you decided wether you want to go with a lexus afm/safc combo or other tuners(piggybacks)
maft pro, emanage, apexi safc, hks vpc, standalone....really it endless

research...theres this real nice feature on this forum
scroll up and theres a search button...use it and youll find what you need or use google
