Greddy manifold to a garret t3 turbo

Just got a new greddy manifold off of ebay (gotta keep the a/c), and for my turbo I have a garrett t3 (.42/.4

. Was wondering if there was anywhere that supplied and adapter plate or if i'm gonna have to make my own.

Thanks

Re:Greddy manifold to a garret t3 turbo

i had that problem on my last turbo kit, i was running an HKS manifold with a t3..the bolt pattern is a bit smaller on the manifold, so all i did was mark the manifold pattern over top of the t3 exhaust housing bolt pattern ,,and redrill/ slot the holes on the turbo..then using a cut off wheel i blended the backside of the turbo housing so the bolts would sit flush..i ran that setup for over 10,000 miles and never had a problem with it..

by the way i think the greddy and HKS manifolds use a jdm t25 pattern, they only fit those turbos..but i may be wrong

t25, 15g, and 18g turbos work with it...not t3

from my understanding atleast...for the greddy

never heard of a t25 fitting, and if it did, so would a 14b, 16g, 20g, etc

JDM T25 and the Greddy Square bore flange is the same thing.. its also the same manifold that HKS sells.

DSM T25/14b turbos do not fit, since they have a circular inlet flange.

Re:Greddy manifold to a garret t3 turbo

I just wasn't sure if anyone made adapter plates. Trying to go for the "clean look" when I put this thing in....not that you'll see the adapter plate....lol. I'll run down to one of the local machine shops and see what they can conjure up.
