Need your expert Single Turbo advise.
 
Well I'm ready to take the next step and make some bigger HP. I'm looking to hit 500whp or more. However, I'm really looking for some reliability as well. I'm looking for a single turbo setup and anything else that I need to go along with it (Fuel Injectors, Port, etc). Here's what I have on the car now. Currently this car is at 310rwhp on a conservative tune from Rotary Performance. The budget, I'm hoping to keep it under 7,000. Here's my current parts list. The car is normally used as a weekend car with some highway and 1/4 mile racing.

* Apexi Power FC Commander
* Stock Port
* Stock Twins
* Full 3" exhaust w/high flow cat
* GReddy cat-back exhaust
* GReddy y-pipe
* GReddy intercooler
* Pettit intake
* Aluminum AST
* RP high flow fuel pump
* Fluidyne aluminum radiator.
* Greddy BOV
* HKS Coilover Set (Fully Adjustable)

Thanks in advance for your advise.

A thing to consider is the primary use or uses of the vehicle. Drag, Auto-X, Circuit, Street, etc...So depending on whether the car will have a sole purpose or require a dual personality. Knowing this is half the battle. Being that it will help narrow down the turbo prospects to help you attain your power goals while remaining effective for the purpose of the car.

Become familiar with compressor maps and it'll be relatively simpler to make a decision based upon the supporting mods and engine parts. You might want to consider some port work also, to make reach your goals a lot more efficiently.

Lastly...the search function will be your best friend. Most likely there are multiple topics just like this one that you can research and see what's worked for people who are or were in the same position that you're in now.

Good luck and keep us posted.:icon_tup:

I'm looking mostly for a street setup. This is not my daily driver. More like a weekend play car. I have done some searching and originally decided to go with the Greddy T78 setup with bigger injectors. However, some people have told me that I will not be happy with the power lag for a street setup. Rotary recommended the TD06 setup, but don't think will get me to over 500hp.

I give kudos to you for having a realistic budget.

Read the FAQ thread in this section, and also go to the garret turbo website and learn as much as you can about compressor maps and turbo sizing

You are correct, the Td06 kit won't get you 500hp. And yes the Greddy T78 is laggy.

Probably going to take a To4Z at 22psi to get your power goals. Its not laggy on a good setup either, expect 1 bar before 4k rpms..

If you go GT35R, you can reach your 500whp goal AND have a auto-x car.

At least you're dealing with Ari. He's a good guy and actually knows what he's doing. In your budget are you accounting for labor or just parts? With your list you'll be right there with just parts...

The most important thing to do though before you even think about going single turbo is to make sure your motor has no leaks, overheating problems, or any other issues. Adding more power only tends to elevate these problems.

The next issue would be to have the health of the motor checked out. Have a compression check done by someone reputable. After both of these are taken into account then you may realistically look into a single turbo setup...

Thanks mono. I have already had Rotary Performance do a check on the entire engine. Everything checked out fine and very healthy. My car is very low mileage at only 49k original miles.

Thanks for everyones input... Please keep them coming.

BTW, What does Auto X car mean?

caredden 09-30-09 11:43 PM

Auto X = auto cross. Again, take Frostycrowd's recommendation to do some reading of the FAQs. Don't expect everyone to just "feed" you info. Look at different setups (again a sticky). Read...a lot.

After all, this is the first time this question has ever been asked...

I like my turbo, a PT-67 with 0.81 exhaust. It is very similar to the t04r and t04z. Its ball bearing so it is a good street turbo. Do the port work, you will reach your goal easier and get the great rotary sound with it. Every thing else you need is in my signature (But get bigger injectors like 550/1600 or 850/1600, 23psi and you are good to go.

for 500 to the wheels on stock port you are going to need more boost and better fuel (race gas, E85) or some kind of A/I
