The Greddy Kit is laggy but has proven to make big power. And the Manifold WILL crack, it's just a question of when.

 

This kit has the revised manifold with dual brackets underneath to help prevent cracking as much as possible so hopefully it will help (cross fingers). The timing is right on as is my current tune, I'm getting better than average mpg with this kit due to the tune compared to my last kit (white rabbit & same EMS). Spool-up is a little up there around 4200 rpm but I don't mind since I'm getting such good gas mileage. Once boost does come on though it's a steady or constant surge of smooth power all the way to redline instead of a big hit like other turbo's. The kit was touted as being a great track kit which is easy to see once behind the wheel because there are no surprises with power delivery, it reminds me of a V8 Top End power seems pretty good as of now but I honestly haven't had the chance to open it all the way up nor have I driven it on the high boost setting yet which I have set at 25 lbs. It was dynoed at 21 lbs. with hks 272's which I'm replacing with Tomei 280's on Friday.

 

is anyone out there in this forum that actually has this kit installed?
greddy T67 or 25G?

 

Make sure you run 23PSI. That is fine for pump gas, race gas should be tuned on 28PSI or so. I can run 23PSI on my OEM turbo and OEM fmic, It is a cake walk for a turbo that size.

Good luck man, and seriously run 23PSI.

 

i think your gettin alot of name when you buy that kit, the kits these guys mentioned are great and you really wont have that much trouble spooling a 30 or even 35r..i think ams website sais 35r is btween 3600-4200 so thats not bad, i would say stay away form G-reddy.lol
