Hey guys--
I've been trying to search and find information in regard to the iHI VN14 turbo which were released on the Autech edition S14 Silvia. I found some limited forum threads on the matter but wasn't able to find the information I was looking for.
A little background on my set-up...I'm running an S14 SR20 with an HKS FMIC, full 3" turbo back exhaust system and a walbro Fuel pump . I replaced the standard T28 turbo with the iHi turbo that I got from Marco at SR20 store in Gardena, CA. I also am running an HKS internal wastegate. The turbo seems a little wild though even with the HKS wastegate. It wants to spike pretty bad. When I adjust the wastegate, I'm aiming for 11psi. Right now first and second gear I only seem to be getting about 7-8 psi until I hit 3rd gear and then it wants to spike to 12-13 psi. Do you think the there is a problem with my wastegate?
Any thought?
