Turbo Exhaust manifold on FC
 

Hello,

I am a new member and wish to give credit to Kevin for rebuilding my trashed JDM T II motor. I have an SS Autochrome exhaust manifold and want to install in on the motor. The manifold required a t4 turbo, could I use my stock turbo with an adapter? What is the classification for stock turbo on 90 T II? THere is an adapter block made for T3 to T4.

Thanks

The stock turbo is SIMILAR to a T3, but it isn't a squared "4-bolt" flange, it just has a slant to it and will not bolt to a T3 flange.

You will need a T4 turbo as I don't believe there are any adapters.

there t4 to t3 adapters on ebay but there quality is....sketchy.

Well, mistake #1: Buying SSAutoChrome ANYTHING!

That shit is SUCH a rip off, and I only heard bad things about their products.

When his products first came out that s what I heard.. but alot of people I know now who use it say good stuff about it..

remember ALL aftermarket or custom made headers will eventually crack why not buy n inexpensive one have it last a couple years and then buy another..

Another thing u can do is send it to JetHot and have them jetcoat it that will help strenghten it and also u can weld in a few "helpers" to help support the weight..

Or spend $350 on a HKS cast manifold.

The stock manifold is fine for the stock turbo.

yes but if u are changing to a T3 or bigger turbo then the stock manifold wont work..

also the stock manifold AND the hks cast manifold still cracks too.

If anyone has any positive experience with turbo headers manifold on T II cars, please share any dyno whp you may have comparing to stock.
SS Autochrome turbo exhaust appeared to have smoother exhaust flow than stock T II manifold, how much of an improvement could it help given the same set up with an exception of t4 turbo on the same motor?

Thanks

weld a support rod onto the manifold, close to the turbo, to help support he weight. that should help with the cracking
