Turbo Upgrade?

hey i have a 95' GST stock and want to buy a turbo kit for it. Which would yall recomend for this car. I want it to be a street/strip car.

Let us know a few things first:

1. What is your power goal?
2. What kind of budget are you on?

And also, before you can upgrade the turbo, you need to do a few supporting mods first. However, depending on your power goals, the supporting mods will vary.

Well i want to have about 400 or more hp. My budget is how much im willing to save.

guitarX nailed it. you'l need all the supporting mod first for a new turbo upgrade. it needs to breath well first to be able to utilize the turbo. ie. intake, exaust (3" the best). you're best bet'll prob be a small 16G or big.

Well, since you said you want it for a street/strip car, then I'd think either the evoIII big 16g or an 18g. You could go with a 20g, but that's a bit big for a streetcar, and you'd need a good bit of supporting mods.

well for sure ill need the intake and exaust(3" for sure) but will i need bigger injectors better fuel rail and better fuel pump

YES!!!.. definitely. more air means more fuel too. or it won't run right. fuel management upgrade will be your supporting mod for that bigger turbo too.

HKS has a turbo kit and comes with a T3/T28 turbo would this be a good kit

correct me if i am wrong, i think T3 is a much bigger turbo than you need. generally speeking a EVo big 16G would be the best choice for most people's need ie. everyday driving and street racing.

i found a kit with a T3/T4 turbo for a little less than 2G. it has an external wastegate? I know a dump tube goes to the wastegate, but does it hook up to the exaust? if so then where

oh ok so just stick with the big 16G

the dumptube goes back to the intake pipe while external WG hooks up to your turbo. your turbo is connected in between your exaust manifold and downpipe

Well i want to have about 400 or more hp.

'About 400hp' is 20g or t3/t4 zone. About the limit for streetability for most people. Somewhat unrealistic unless you already know what you are doing, but since you quoted a turbo kit you were looking at for $2,000 I will assume you wish to spend some money on your car.

There are a lot of options for you. Going for anything over 16g level power will start costing you in supporting mods. EVO3 16g's can make 325-375hp depending on a few things. What do you really want by upgrading? You can never make a decision unless you say what 1/4 mile time or horsepower you want, and then again, who knows exactly what they want in horsepower without knowing what it's like?

I'd say get an EVO3 16g or 20g. If you need MORE than 375hp, there are still options for you, but then I suspect you just want info (easily found by searching) and are not really going to do it.

but will i need bigger injectors better fuel rail and better fuel pump
Injectors and a pump. Maybe a FPR depending on the pump. Fuel rail is not a common upgrade for a DSM.

HKS has a turbo kit and comes with a T3/T28 turbo would this be a good kit
Negative. For one, HKS is expensive, and mostly because it's uncommon and not proven (read: probably not fast compared to a regular T28). T28's are around 16g level, but are more expensive.

i think T3 is a much bigger turbo than you need
T3 means the exhaust side when said as 'T3/T4' or 'T3/T28'. Stock exhaust manifold bolts up to a T3, which means the stock turbo is one (i think... it may just mean it FITS one). Turbos with T3 compressors aren't that big. There are some BIG turbos with T3 exhaust sides though. So T3 exhaust side doesn't indicate power level.

i found a kit with a T3/T4 turbo for a little less than 2G. it has an external wastegate? I know a dump tube goes to the wastegate, but does it hook up to the exaust? if so then where
Depends what kit. Some external wastegates bolt onto the exhaust manifold, some onto the o2 housing. The situation you mention is the o2 housing (attached to the exhaust side of the turbo) having a pipe to the external wastegate. Then, the exhaust can be either routed into the downpipe (or o2 housing again), OR dumped into the air. This is what i'm talking about:

yes thats the picture i was looking for but coundt find it

what if you have a T3/T4 but you turn it on low boost would't it be more streatable

and wagon i do know what im doing i just thought id ask for advice but you had to be a dick about it

i don't think joe was being a dick about it. he's just trying to help out. in theory you CAN get a much bigger turbo and lower the boost, however, you have to take the turbo lagg into consideration.

ok i understand sorry bout that coment, anyways ill guess ill still with the Big 16G

Could i buy the EVO VIII Manifold and put the Greddy !8g turbo kit on it

IF you are serious about 400 whp, and you know what you are doing, I would suggest the TDO6H 20g to stay bolt on, or an AGP 50 trim t3t4 kit if you just want to say you have a t3/t4 ;) Both will get you there. Sure you can throw a huge turbo on and just turn the boost down. But a 56 trim at 15 psi will get smoked by a 16g at 15 psi, because of the extra lag. ;) So choose wisely. I like to go a little big, so I have room to grow. But of course now I have a turbo that doesnt spool until 5000 rpm,which wouldnt work for most poeple. :D

More important than turbo choice is how you plan to tune this car. AFC/logger/chip, or DSMlink? Tell us what fuel you plan to make 400 whp on and I can tell you what you will need for minimum fuel mods. To see what makes 350 whp on a 16g, see Joe Gs mod list on my website.

i want to make it on pump gas

dude.... buy this... a big fmic, SAFC, fuel pump, 660s, a big 16g, a clutch, greddy bov, cone filter, 3in downpipe to 3in full apexi n1 exhaust (like me :) then your car will hit 12s that is about $3k right ther... depending on wher you get it, it can be more or less... be sure to search ebay and www.dsmtrader.com good luck and be safe...

I just upgraded my turbo on my 95 gst. I went with the small 16g and let me tell you, that turbo is awesome. I aam only running 8psi boost and i still have the stock fuel pump and injectors and i ran a 13.9 at the track in the 1/4. Once i change the injectors and pump i can up the boost to like 20psi and if i can hook up im thinking i should hit the low 13s or high 12s with more work avalible on that turbo. So the Small 16g is a sweet turbo dude.

alright man thanks for the info

For 400 whp, a 16g wont help you. I would recomend a TDO6h 20g, SBR sells one for 999. Big front mount, 255 and FPR, and at least 660s are all mandatory. Bigger injectors if you go with DSMlink or a Jeff O chip, or for an AFC if you never plan to run race gas. . ;)

With all the shit I typed, I can't believe you called me a dick. For one, you DON'T know what you are talking about really.. asking if you could do all these things. I gave you options, so did a lot of people in the thread. If you want to run 12's, a 16g will do fine for you. If you want 400whp (lower 12's) then you need to get a td06h 20g, or a 50 trim T3/T4. Don't BS me and say you know what you are doing... because you could have searched for all 20 of your questions all throughout this thread. I'm still willing to help you, so let me know what you think is necessary for your car.
