Default turbo critics needed?

Hi everyone. Will be purchasing a turbo set-up and am wondering opinions.


Have been looking through the forums and magazines and have noticed two different set-ups other than the Ultimate Racing or the Rev hard systems turbo kits.


One particlular set-up was in the new Honda Tuning magazine and featured a Garrett turbine with dual ball bearings. The other was a thread on someone using a 81/60 t3/t4 or something of the sort.

1.What turbo do you use and what is the turbine ratios?

2.What management do you use? I was thinking of the Greddy E-manage. What is your opinion? Most just say to go with a Aem but I only want to run max 7-8.5 psi at the moment till the motor goes bye-bye.

3.What intercooler size did you use?

4.I do plan on using a electronic boost controller and turbo timer for safety so I won't need input with that but thanks.

5.What injectors did you use? Any fuel regulator issues?

6.Is there any problems other than the usual blown rear end and fried clutch that you ran into.

7.My goal is 330hp to the wheels under 7-8.5psi with the larger type 81/60. Am I being unrealistic here. I would be happy with 310 but I have seen written that the Honda Tuning S had 387hp at 8.5psi but of course there could be other factors that were not mentioned to get this number such as a 40hp shot of nitrous or something similar.

8.Thank You all in advance for any input you can give. When I get this project started in Febraury I may post a write up and results when I am done. I am going to have Turbo Technologies here in Tacoma, WA do the work. If you have any comments on this shop don't hesitate to mention it.

10.I have a a/f gauge and boost gauge and will add fuel pressure, egt, and an oil pressure gauge at time of install.

11.I also know of the oil relocation kit.

12.Manifold. What do you have and how well does it work for you. I was looking at a stainless unit from Turbo unlimited.
Thanks
chris

I have the car in the current Honda Tuning magazine. It uses a Garrett GT30R turbo matched to a Full Race manifold. The car uses Greddy emanage and Profec E01 boost controller. The intercooler is a 4 inch and the bov is from Apex racing and wastegate is from Tial. The car makes much more than what you are looking for at 7.5 psi. Without nitrous, the car produces 404rwhp at 9 psi and 287 lbstq. Unfortunately or fortunately I have dismantled the car and I am currently creating another setup since that was on a completley stock motor. Hopefully, we can then begin to boost a bit higher and spray...

Both kits you mentioned have served well for many people but I think folks have found others ways of producing more power efficiently with other products. You will have to create a budget first so you know which direction to take. The kits you mentioned are the most economical out there. It usually begins around 4.5K and goes up to around 8K.

If and when you are ready then PM me and we can talk further. Good Luck

Go with as small of a core as you can for the FMIC. How would a boost controller provide safety?

Oil relocation kit...Ultimate-Racing. I still havent found one that fits better or is lower profile than theirs.

Get picky on injector sizes depending on how much you drive the car. Going too large on injectors with a piggy-back will give you some part throttle issues. If you can get a high pressure&flow fuel pump, adjustable regulator and 440cc injectors that would keep it pretty close to stock drivability.

If you have a wideband a EGT sensor is pretty useless.

Like said above. What's your budget?

The manifold (fullrace) is very efficient and produces much more power compared to the log style manifolds. You can attribute the nice numbers on the manifold design and good tuning.

I think your forgetting something else that's very important. Turbo efficiency. It's nice to think the manifold did it all, but that's only part of the equation. His exhaust system adds a good bit more ponies as well.

It was really late basically the whole kit is well thought out and matched pretty well. Down pipe, exhaust, turbo, etc...
