Potential problems w/ the supra- Flammers please stay out SERIOUS THREAD

[The Ren]

Thanks Mike.. I definatly appreciate the help.. Remember Im still very new to the supra world so.. Dan told me he thinks its definatly a cause for concern but something not to loose sleep over. My car is still pulling hard and drives fine...its obviously not to the full potential it can be at but at 338hp its still got decent power..

[Vteckidd]

oh its at batlground, i didnt know that.

yeah just go with what they say, i would still get an AFC an tune it to see what power it makes just for grins.

good luck

I am still ganna go single and I am still ganna get my fmic... once I do that I will get my afc and then go from there..

Why? You just said you drive with the boost controller off, so I'm assuming you're running less than 10lbs daily. That thing would be a pig with a huge single running off the wastegate.

I'm not trying to knock you, seriously, and I hope you find and fix the problem with your car... but what is the point of building a 600+whp car if you don't drive it??!! If you're not comfortable with a fast car - why are you building one?!! You're better off sticking with the stock twins and keeping it at a moderate 400whp or so, there's nothing to be ashamed about that.

Build the car for what you want, not what everyone expects. If you're building a supra with big numbers but you run with the boost controller off on the streets, it's for some other reason than you honestly want a car with high horsepower.

If you're comfortable with 400whp, then keep the car at 400whp and save a shitload of money. Plus you have a lot more drivability with the stock twins than you would with a huge single that will hardly spool if you have the b/c off.

Just my

I suppose there is always the fun of building a car... Open it up occassionally at the track and events.

If nothing was lost in translation though... i totally agree with what val said.

[Xrated O.G.]

does it burn oil? what im saying is, a COMPRESSION test will give you a number. It doesnt tell you whats wrong with it.

for instance, you could have a bent valve or a bad piston. A leakdown will tell you the amount of air getting past the particular cylinder. an tell you if its the bottom end or the top end.

i guess i have heard how so many Supra motors especailly TURBO GTEs are indestructable an good for 600whp, i find it EXTREMELY hard to beleive your bottom end went out.

You need to know what a/f ratio you are at, perhaps is so rich it washed a ring out. you need more info before you decide to rebuild it.

ask more questions get more info

Well said Mike.




I would get to the root of the problem before doing any other upgrades/modifications. The bottom ends on those cars are damn near indistructable. Doing the work on those things are SO SIMPLE.... Its really nothing to remove the head from it if it is a valve or anything else in the head. To continually drive the vehicle with ANY type of symptom or problem is only going to cause more inevitable damage to the engine. If you have some other means of transportation than I suggest you use it. Stop driving it till you know exactly what is wrong with it. It makes no sense to keep wounding the motor when you don't have too. Just my $.02 so take it how you may... Hit me up if you want or need any help. I am not too far from you in Winder....

LMAO..... I would love to take a look and see whats up with the Supra....

You have to go in order here....you can't just slap a big turbo on and drive the car. 1st fix your car so that it runs right as it sits now. Then once you get that taken care you'll need supporting mods for the bigger turbo. Which will include bigger injectors, but in order to run bigger injectors (correctly) you will need a way to tune the car (s-afc or any other tuning device). Btw way, I gave you my compression gauge when you bought the car....you could have tested it before buying it.
As far as the 15.1, I also think it has nothing ot do with the car but rather with your driving. You ARE making 340whp, reguarless of being tuned or untuned and reguarless of your compression. If a stock supra with less power than you runs 14's, you should be going faster because you DO HAVE more power. That's not to say that you wouldn't have more power (and therefore still faster times at the track) if you fixed your car, but as it sits you should be running faster than a 15 with 340hp.

[Vteckidd]

I also agree with Val (*GASP*) If your happy with making 400whp, then why sink money into a single turbo. no need for it IMO.

I just think IMHO that you are ASSUMING alot right now based on LITTLE INFO. I would personally ditch all the electronics, use an SAFC an a boost contoller an get it tuned. See what power it makes THEN. respond back here with the a/f ratio graph.

Slapping a single turbo on an already low compression cylinder is another mistake. right now the only mistake you have is a car with upgrades an no tuning done what so ever. big no no. bite the bullet, buy an SAFC an tune it. Youll need AT LEAST an SAFC with the single turbo anyways so its not like its wasted money. If you tune it, the comp numbers stay low an you make crappy power, then look towards a rebuild.

You keep speaking as if you may have some sort of knowledge on the internal combustion engine. Do you work at Jiffy Lube?

[Big Baller]

Get the big single

[Dragonfly5338]

DAMN!!! Hahhaa!

Matt, shut up. This is about what Ren wants for her supra not what you want for it.

[PSINXS]

ren if u gonna go single do it right. a t61 is a waste of a turbo IMO> Its a small single and will make at most in 4XX range on stock fuel system. If all u want is in the 400s a strong BPU++ will get you there. IMO Get a big single, do the fuel system like you planned, TH400, and have fun.

[Vteckidd]

i would do a B16 swap, VTTTTTTTTTAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAKKKKKKKKKKKKKKKKKKKK

[iloveboost]

Big turbos make all problems disappear. It should also help with your low compression cylinder.

get it right, its MEINEKE!

[The Ren]

I plan on going single in the future.. not at this point and time, I still need to get more comfortable with my car before I go single.. as I said though I still have plans to do it. Stock boost on my car is 13lbs. I havnt really decided what turbo im going with and I still have plenty of time to figure it out. For the immediate future I am keeping it where its at. Right now until I get a daily the supra is my only means of transportation since my other car is being used by my boyfriend who drives to work in buckhead everyday and my mom is still in need to use the tracker till she gets her other car. Believe me If I could keep it in the garage and not drive it I would.

[MongolPup]

Now I might be a little noobish, and I sure as hell don't have a supra, but why is such a popular mod a single turbo conversion?

If its all about more boost, it doesn't make sense why you would go to a single. More boost (as in enough you can't use the stock ones) means more spool time; isn't it better to have the sequential turbo thing going on?

Point is, couldn't you have an ever BIGGER turbo if you had a smaller (still bigger then stock) one to "pre-spool" it and give you quicker power?

Like I said earlier, maybe I'm not right or I have the wrong idea about how the twin turbo style thats in the supra works, but hey its a learning experience right?

[Vteckidd]

more power is had through a Single turbo. thse arent 4 cylinder motors, they are 6 cylinder.

You eliminate alot of issues with switching to a single turbo. with todays turbo technologies you can get a turbo that will spool an still make sick top end.

WTF???
