which one to pick

[500hpgsx]

im new to the turbocharge world and need help to pick the right set up for 400-450hp on a 1999 gsx automatic i know its a auto please to flame me. but i want a nice dd but also give some US muscle fight if they want a fight. im having a problem on picking a turbo i want to upgrade i have a stock one now . and i was thinking the evoIII 16g or the turbonetics t3t4 form dsmotorsports. and was thinking which one is the better for a build up i know that the evo will be a direct bolt but i want more power. can anyone tell me how hard is it to make the t3t4 work (ic setups, any exhuast fitting problems) things of that nature. or will it be more cost efective to just go with the evo.

any help would be nice

You really need to read this first:

While the EVO III is capable, I'd get something larger that will make 400-450 easily instead of using a smaller turbo that makes tons of heat. T3/T4 combos work well, but are not necessary considering we have plenty of hybrid ball bearing offerings that will make those numbers without breaking a sweat. Nevertheless, the majorty of us would be running T3/T4 combinations if we had the funds to spend on them.

Read up, do your research and then decide.

Good luck,

Andy

ok then which turbo would you go with if you were looking for these hp numbers that wouldnt cost me a arm and a leg

you can get a bolt on 50 trim with a 38mm tail external wastegate rerouted into the exhaust. I think that would be your best option, the sbr exhaust manifold tapped for a tial 38mm, with the dejon exhaust that reroutes it back into the exhaust, and a simple 50 trim.


But I also think the most important thing in modding a car is doing the research yourself and making the decision for yourself based off of what you find. Asking questions is a good place to start, but with these extremely well documented sites, you can research and find that a lot of people have already asked the same questions you have, and the answers are sitting right there for you. Do it for yourself and you'll have a much better understanding of whats going on in your car.


btw, cheap reliablity is somewhat of an oxymoron

I already have it. I run a Garrett 50 trim. Since I didn't buy this turbo brand new if I had my choice I would have picked up either a ball bearing 50 trim, a 57 trim or a 60-1. All of them are great on pump gas and since that's what I run all the time, I'm pleased with my choice.

It's more about how your parts work together and your state of tune than the size of the parts. Having come from the Mustang world, I saw tons of people put huge cams and intakes on their 302's since they thought that bigger was better. I used to eat these guys up at the track because although I had less high dollar parts, mine were volumetrically efficient and worked well together.

Turbo systems are the same way. In January of 2005, I didn't know the diffrence between a BOV and an MBC so take your time and do plenty of research. Your head will absolutely swim with the amount of information you'll be absorbing. Worst of all, each one of us has a different opinion about what it takes to make the kind of power you're looking for. Some might recommend a stroker, while others will say that a smaller turbo is enough. This isn't a difficult process, but the number of opinions you'll receive will drive you crazy.

I'd like you to do something different. Use our site as a reference to learn and build on your knowledge, but when it comes time to start your project, try to filter out the mass of opinions and look for straight facts. It'll make this whole process much easier.

Let me know if you need a hand,

Andy

yeah i didnt know that picking a turbo would be this dizzing i read all the time on turbos and your right my head is swiming will the info i read on them.

No worries. Just keep in mind that a complete system contains the properly matched set of parts:

1. Turbo
2. Intercooler
3. Intercooler piping
4. Blowoff valve
5. Fuel injectors
6. Fuel pump
7. Fuel pressure regulator
8. Cams
9. Engine management (DSM Link recommended)
10. Trans upgrades (valve body, shift kit, higher stall converter)

All of these are moot if your motor isn't properly maintained. Running a compression test is first on the list. There's no point in modding something with blown rings that eats oil. Make sure the major service is done (timing belt, tensioner, idler, water pump, etc) and then look into doing your mods. Keep in mind that a big turbo on stock injectors isn't very gratifying so don't necessarily upgrade in the order that I listed above. Every upgrade usually requires something to be in place before and something to be added afterwards to work well (unless you do all of this at once).

It's a long road. Just be patient.

Get one. It's one of the single best mods you can have and there's nothing more important to a motor's health than tuning.

No worries. Keep updating this thread so that others can see what direction you're moving in and learn a thing or two.

Also, I neglected to mention that a 95 EPROM ECU will work fine in a 97-99. You need to switch the two inside and two outside plug wires on the coil pack. The signal for the CAS needs to be inverted, but this is something that you can handle from within DSM Link.
