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/.48). Was wondering if there was anywhere that supplied and adapter plate or if i'm gonna have to make my own.

Thanks

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

your absolutly right on the turbo specs.
what you might wanna do is either one.

port the holes to match like he said.

or
hmt way just make an adapter plate.

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.

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.

get a nice heat shield for the manifold made to hide the ugly adapter plate then..

All I gotta say is Adapter plates don't show up on time slips ;)
