Turbo Upgrade Advice
 

I have a 97 GSX with ACT 2600 clutch, catback exhaust, boost controller and running at 15 psi on my stock t25. I want to upgrade to a bigger turbo but I can't get a front mount yet because of my parents. So I was wondering what are your thoughts on upgrading to a 14b and a supra side mount? With a supra side mount it will just look stock from the outside and my parents wont know I did anything. Also, what supporting mods would I need for a 14b upgrade, if any? I know it may not be the best upgrade but I think it would at least be better than my t25. I'm tired of getting harassed on the road and not being able to do anything about it.

Re: Turbo Upgrade Advice
 

wait.... you parents will yell at you for having a frount mount? What about your exhaust? Shouldnt they yell at you because of your exhaust instead? LOL

Re: Turbo Upgrade Advice
 

Well.. yea but it came with the exhaust when I bought it :)

Re: Turbo Upgrade Advice
 

T28/Big28 would probably be your best bet.

Re: Turbo Upgrade Advice
 

I agree with Kracka. Either that or a 16g (small/big/evo) would do you just fine also. Your going to get sick of the 14b after awhile and be askin the same question again. So I'd save up over winter and just start slowly buying things. I'd get bigger injectors, fuel pump, S-AFC or DSMLink, and a 16g or T28. Good luck.

Re: Turbo Upgrade Advice
 

cool, thanks guys!

Re: Turbo Upgrade Advice
 

you could also run a 20g with a supra sidemount if you have the other supporting mods. I ran it without a problem that way at least

Re: Turbo Upgrade Advice
 

Plus the T28 is a stock bolt on, unlike anything else including 14b's. Nice, easy and simple. The stock IC is good enough unless you're going to run crazy boost.

Re: Turbo Upgrade Advice
 

Get a FP Big28 or a T28 or something like that.

Also, I didn't see a downpipe listed, or I am just blind, who knows which. Get a 2 1/2 or 3in downpipe as well, that will show some gains.

Re: Turbo Upgrade Advice
 

Alright, thanks everyone. I want some power but not too much for right now so I think I'm going to go with the t28 and leave the stock intercooler. And yea I need a downpipe. With the crankwalk nightmares I've been having I'd rather wait to go big so not to help speed up the process. :) .. yes two days in a row, I've had crankwalk nightmares lol.

Re: Turbo Upgrade Advice
 

crankwalk is just an excuse to upgrade

Re: Turbo Upgrade Advice
 

Get a 2.5" downpipe along with testpipe; you are going to want either a fully ported o2 housing or a tubular one. Do you know what kind of catback you have?

Re: Turbo Upgrade Advice
 

Skip all the BS and go straight to the 67Trim, you won't regret it!

Till something breaks........:-P

Re: Turbo Upgrade Advice
 

Ha, lag lag lag lag lag.

Just put a FMIC on it. Your parents might notice that monstrousity Supra sidemount hanging down all wacked out in your wheel well.

Get a downpipe. get an uicp / blow off valve. Get an intake filter (pipe if you really want it).
Then upgrade your stock turbo to a direct bolt-on t-28. Raise boost to around 17psi. You would feel the difference. You won't need supporting mods on the t-28 unless you go higher. 17 should be safe. Just don't beat the crap outta the car.

I wouldn't go 14b. Stock to Stock, why not just get a bigger upgrade?

Re: Turbo Upgrade Advice
 

just fyi.

The act2600 would put alot alot more pressure on your crank.
This increases your chances of getting crankwalk.

Re: Turbo Upgrade Advice
 

I have an Apexi N1 I believe.. but theres a hole where the muffler meets the pipe from rust.. damn salt, so I guess I'll have to get that fixed before I do my upgrades.


Bahh I know.. it's a long story. I was going to get a ACT 2100 but I had such a limited time to install a new clutch because my factory clutch went out and this is my only car. So I ended up getting a ACT 2600 with 1k miles on it from a friend.

Re: Turbo Upgrade Advice
 

You could put a front mount on and paint it with a very light coat of flat black so it doesn't stand out. ;)

Re: Turbo Upgrade Advice
 

Just get all the upgrades you want and when the parents ask, just say "it was there when we bought it." :D Normal parents wouldnt know, unless they're mechanics themselves. I had the exact rust problem with my N1 exhaust, haha. You can get a nice front mount off ebay and paint it like Vicious said. They'll never notice...

Re: Turbo Upgrade Advice
 

Do the big T-28, and dsmlink if possible. If you do get the T28 make sure you have your O2 housing ported out. I did the same thing and had boost creep problems until I got the housing ported. Stock injectors should be good for a while but you will want to replace them to make the full potential out of the turbo. Add in a new intercooler and you should be good for low 13's maybe a 12. Best of luck.

Re: Turbo Upgrade Advice
 

No it doesn't.

Re: Turbo Upgrade Advice
 

He's saying the 2600 takes more pressure from the TOB side to release the disc, which pushes the crank into the thrust bearing harder.

Re: Turbo Upgrade Advice
 

whatever you do, don't do an 18g...I got one on the cheap, and it takes forever to spool...nto fun for a street car, but makes life great ot highway speeds...lol

Re: Turbo Upgrade Advice
 

What are the specs of your 18G?

Re: Turbo Upgrade Advice
 

it's just a straight out the box Greddy 18G, not ported/clipped. I don't have the specs on it...why?

Re: Turbo Upgrade Advice
 

lol

That is what I was going to say for obvious reasons. Defainately not as fun as a good old 50 trim on the 2.0.

Its hard to suggest anyhting without knowing what you want performance wise and what you want to spend. If you know someone with a known good 14b, you could pick it up cheaply enough and get a little more boost out of it. Buying a random one may cause you to spend time and money bolting up a crappy turbo.

If your budget can stomach it a big 28 or even a 16g variant would be nice. If you don't see yourself doing cams, the small 16 is fine.

Re: Turbo Upgrade Advice
 

Yea someone I know had a good 14b so I'm just going to use that. I'll go all out when I'm able to build my motor later on. I was just afraid I might blow something up or screw something up if I went to a t28/16g with all my good luck :rolleyes:
