i dont no if any one remembers but awhile back my step dad was goin to race a supra but his engine ended up blowing 2 days before, but i am tell u this guy wont stop. so i need your guys help to show him the domestics RULE! lol anyway he has a 87 toyota supra 3.1 turbo. i no its stock he says its not but i think it is (he still has the stock exhaust system on it, but he has some tip, and he dont no what a K&N air filter is, if u mod u should no that) hes sayin he will kill any domestic because they are so heavy. please tell me what i have to do to beat his A$$!! i will do anything to the car that needs to be done. i have till june.
i got now 305lg4 with headers custom y pipe 3"pipeing, freeflow converter, flowmaster muffler, k&nfilter, custom cai. thats it. will he still kill me. can i do it with a 305 with some more mods or should i get a 350??? please help me.

 

i think you should be able to beat him with the 305.. you have some good mods already! have you tried racing him with what you have now..

 

Auto trader's got some specs on it. Thing weighs as much as an F-body, bit has more hp and a small amount less on the torque side. Might want to be careful. http://www.autotrader.com/research/m...&ac_afflt=none

 

I would watch out. A friend of mine has a Mustang with some mods and he raced an 87 Supra. The Mustang won then the Supra upped the boost and beat the Mustang. If he has any mods you can bet he probably has more boost, and with more boost he could be running very fast. If he is stock it should be a good race, but with more boost I think he would win!

 

I don't know what kind of tranny you got in there,but I will assume you have a 700R4, but look into buying a torque converter and mybe a shift kit for the 700R4 some 3.73 posi in the rear and I would say you should be all set. If you have a t-5 lookin into getting a 3.73 posi unit! Good luck

 

ya i got a 700r4 tranny but i dont want the shift kit my engine is low km but the tranny on the other hand has never been rebuilt and i dont no if it can take it.
what do u mean boost? like mod? or nos?
i am goin to check into the tq converter and posi on monday. i was thinking a edlebrock intake and carb as my next mod what u think? i will win this race even if i have to get nos.

r these # true?
1986 Toyota Supra 7.0 15.4
1988 Toyota Supra 7.9 16.0
1989 Toyota Supra Turbo 6.6 15.2
oh one more thing the supra is standers and i'm auto, that cant be good.

 

1985 Chevrolet Camaro IROC-Z28 7.0 15.2
is that right i dont think it is.

 

by boost he means on the turbo, more psi=more h.p.

 

Yup, but that was for a TPI 305, which that year was rated at 60 more HP than the carbed LG4.

Even though you did good by getting rid of that horribly restrictive stock exhaust, your highway gearing should keep you from reaching high 15s. That Supra WILL beat you. Don't race him. Instead, go talk to an LS1 owner about the "domestics being heavier" deal and have them race. Once he gets humbled by the LS1, then challenge him to a race. He'll probably back down.

 

really? my 84' LG4 went 16 flat 100% bone stock. so why wouldnt a exhaust upgrade get high 15s for his car?

if his car is in good tune i would expect mid 15s with his setup if he can drive

 

Those kind of mods on an LG4 should put you right there with the L69 as far as horsepower goes. I say get a shift kit, 3.73 gears, and some traction. Oh and I'd get a more powerful ignition system, and since he's playing that power adder game, I'd say you should go for it to, in the form of a 125 or 150 shot of nitrous.

 

That is not an 84. It's a later model - 85-87. And the 85-87 LG4 autos got either 3.08 or 2.73. Chances are its got 2.73s, which would account for at least another .5 second. Add his additional weight into the equation...

 

well, he does have more hp, higher compression, and my car is fully loaded so i dont think his would be all that heavier than mine. he also has full exhaust... and your telling me all that stuff doesnt beat a STOCK 84s times?
i checked the "tech data" on this website, and the only gears listed for an 85 Z28 or IROC with the LG4 are 3.23s

 

lol, he said he'd beat domestics because they're so heavy?

MK III Supras are no featherweights.....

 

I raced a late 80's turbo supra the other day in my stock 1999 GMC Sonoma. (4.3ltr and 5spd) We were pretty much dead even from stop untill 80mph. Then 20mph roll up to 80 i had MAYBE a few inches on him. It was a good race but the guy was a tool. I'm not sure on the specs of my truck but I know it would have beat my TBI Trans AM.

Later

 

Ya those 80's Supras blow pretty hard. I was racing one in my GTA, and during the race the head gasket blew out. Biggest plum of white smoke ive ever seen out my rearview mirrors. HAHA i laughed quite some time on that one. Poor kid didn't even have a chance in the first place.

 

I'm with BILLZ28.... Get a nitrous kit for your car.....

 

ok heres what you do...

1. acquire a summit racing mag
2. order a Merlin II 540 Big Block Blown (900 horses)
3. Upgrade your suspension
4. get yourself a beefed up Automatic Trans
5. open summit racing mag
6. order a Mr Big Shot fogger system (500 shot)
7. buy the biggest tubs you can
8. ask him if he wants to race
9. line up with him
10. PRAY THAT THE TRACTION GODS ARE WITH YOU


thats how you show him what AMERICAN MUSCLE means hehe
either that or you can just get yourself a stock 350 TPI and blow him away...if you have the money the first option would be better

 

Watch out for those year of Supras. I ran one once and barely took him. Though he had more boost than average. Its one race I'll never forget. One word...NAAAAWWWS

 

first thing thanks
for all u guys help i wont let u guys down i will win this race.

NastyEssCee: thanks for the info but if i did all that i would not have my car on the road till next summer, i am still a student money is not that grate i can get thing but it just takes longer.

Jokerman: thanks for the spec now i no.

here is what i am goin to do. get my tranny rebuiltput a shift kit,torque converter
add 1.94 intake valves, edlebrock egr intake and carb and then nos. then give it a shot. i am hopeing that should be enough.

 

Why not get a Mitchell 632 Big Block? 925 horses... Motor...

 

Hehehe... you KNOW an import is 100% stock if the stock exhaust is still there

 

get nitrous and drag radials, seriously, the supra guys are so used to getting pulled out of the hole, they always say
"well i was catching you, then you let out."
keep the highway gears, get a little traction, you might lose a little down low, but with the torque from the spray, it would be gravy.

adam

 

yeah but see the problem lies with this...


I could get my friends rx7 to race the LS1 camaro the rx7 would prolly win..... well if my friend could launch his car...

I don't think it matters if you drive a domestic or import... either one can be VERY fast

 

amen to that

 

ummmmm.... yeah sure he will do that

 

Mk IVs are even fatter. Funny all the truely fast imports are heavier than our V8 domestics lol. anyways, a stock 87 supra turbo should be mid 15s. a modded one would be high 14s. a suped one can be as fast as any suped up V8 or turbo import.

 

I think most of the faster imports are in the 2700-3100lb range... least the stock ones.


there are others though like the skyline and such but they are not here
