1987 A/T supra suggestions

[ochowdero]

as of right now my car is pretty fast,
it may be average to experienced driviers, but for me, its my first rwd and "fast" car.

i wanna get extra hp, i am gonna run a catback with 2 1/2 exhaust, later add intercooler and cold air intake...
eventually ima add turbo and almost all new wiring, spark plugs and leads..

i heard its good to have a scoop, so i was thinking when i get enough money after all that above is done, install a carbon fiber hood with a scoop
anything else i should do to it?

its a 1987 N/A (thanks batmmannn haha) automatic supra, just need alil guidance on whats best for my car.

thanks to all who helps.

n/a means naturally aspirated.. i own an automatic.. I maintain continual boost through my gears... so suck on that !

carefull when you change your exhaust. remember in an NA, a little back pressure is good.

I maintain continual boost with Coffee, Doritoes and Pepsi!

Wow you have so much to learn!!!

My 90 NA auto has more money invested into it then I care to mention and it is by no means fast. The car and driver review put it at 0to60 in 8 seconds, fast for the 80's but slow today. And that car was a 5speed. Your car is 23 years old it needs alot before you worry about things like intake and exhaust, and certainly not a turbo. A turbo on a 7mge is a bad idea. It has been done before and concluded to not be worth the effort or money. You already had a problem with the steering so many more problems are to come. If you want to do it right. Find a 7mgte and rebuild it and then you will have some power worth building on. I'm sure if you look you will find many hoses, leaks, and worn parts to keep you busy for a while.

AND WHERE THE HECK DID YOU HEAR A HOOD SCOOP IS A GOOD IDEA, do some research on the principles of cold air intake like not having a big filter sucking hot air.

Yeah, well my car came together pretty fast without a lot of money maybe his will too. I think what 907 is saying is that if you are going to boost this motor it is too old to be reliable. The rings, the valves, headgasket all have too many years. Better off to do total rebuild before adding boost, by todays standards these cars aren't fast but for the money they are, lets face it, I don't have 20K to buy an MK4 and most young drivers don't either so for a car to be fun and fast great handling and sporty and still be under 2K I think the MK3 can't be beat! The MK3 is the perfect car for a young guy that wants to pimp his ride! If you want a turbo best to sell yours and buy a turbo model.

You don't rebuild a 7mge and put a turbo on it when you can buy a 7mgte that is made for a turbo. Why reinvent the wheel. Its all about power to weight ratios

3600/200 = 18lbs per hp for the 1990 mk3 N/A

2600/180= 14.5lbs per hp for my 2000 celica gts

And just wait for the bhg that will come someday like they do for all unless you just redo the top end first.

hes also saying putting performance parts on an NA is like putting lipstick on a pig. you won't even come close to hitting 300hp even tho your only 60 hp away.. (back in 1991) buying an again sports car and driving it like a brand new sports car is a bad idea. do your maintenance and then if you still have any love for it start saving for a turbo.

There are other differences as well. The Turbo Model has a bolder trans.
