st vs gt, something ive been thinking about Options

[brianforster]

ok so most people on here are quick to say "the gt is better"

well it is , stock.

but in my opinion, if you do not plan on doing a swap, it might be more beneficial to go for an st.

the 7afe has a bigger aftermarket it seems, I think I read somewhere that it responds better to boost , that could be just retarded so feel free to call me out.

I think the person who contributes to this the most is kwanza, Ive read his posts a lot and he has an ST and I want to say it could have probably beaten most of the GT's on this site.

So what do you all think?

In terms of not swapping, just keeping stock or maybe adding a turbocharger, what has the most potential with the most reliability as well

Nik, it's a matter of exponential growth when you're turboing a car; the difference between a turbo'd ST and turbo GT is exponential every psi you raise. Quite simply, while they only start out 30 or so hp away from each other; every psi increases that seperation.

in my opionion, a turbo'd ST vs turbo'd GT race wouldn't be any closer than a regular ST vs GT, even worse.

i agree with this statement but i would still like to see it in real life a turbo st and gt 10psi 1/4 mile isnt the st a couple hundred pounds ligther in stock trim?

Im still saving for a celica and I've decided firmly on an ST for the following reasons.

-Lighter weight. Some of this light weight is due to the ST having dinkier stock bits like brakes, bars, etc. But the most important and sizeable difference is right on the nose of the car. It's the smaller A series block. Lightweight is paramount to my project goals.

-Cheaper initial purchase and running costs. Hey, I'm cheap!

-Easier to find in low trim. Ever noticed it's alot easier to find 6gs with a solid roof and a 5 speed in ST form? No? Must be just me.

-Better engine. Ha! There, I said it! If you aren't going to do a complete swap, the 5SFE has pretty much two real options. You can bolt on a turbo, which is relativly easy, effective and a great cost effective performance boost. Or you can leave it stock and enjoy its natural torque advantages over the average four cylinder.

I think the 7A is a better engine to begin from simply because there are so many options. Mainly with head swaps from other engines in the A family. Considering this, one has the option of mixing and matching the 1.8l 7A bottom end with a series of hi performance G heads and pistons that can include superchargers, turbos, maf or map, VVT, 20v, ITB or any combination of those. Not to mention good old fashioned, inexpensive, and domestically available 16v heads with choice of factory port sizes and even TVIS , if you care for that. With more options at hand, one has a better chance of building a unique powerplant that suits their tastes.

While I would be more than happy with the power levels being produced by Turbo 5SFE engines, the delivery I see in dynos is not what I'm looking for. I wan't an engine that can develope good NA power at high rpm and sustain it for hard driving. That option just isn't available to me from a 5S. Anyhow, that's my rant.

You can actually do head swaps on the 5s using the 3s heads. Its been done. Then you got the option of going V6 with the 1mzfe. To my understanding, most of the mounts match up. Not like I would really know anyways though.

AHHA! Please help me out! I've been desperatly searching for info on 5SGE and I can't find crap! I just figured the bottom end was over square and wouldn't see any gains so nobody bothered. Can you tell me where to get some info about this or contact those who have done it?
