Long story short, the water jacket broke on the rear iron. I have some S5 NA irons sitting around, can the rear iron be used on the S4 T2? I will check to see if they're usable of course.

Any other engine/year that is compatible in case I can't find an 87T2?

Thanks

 

Ports are nowhere near the same. Contact rotary resurection he was selling some for cheap recently i think.

 

Damnit...I'll look him up. Thanks.

 

put them side by side and see what the differences are. the most noted difference is the beefier casting of the S5 plate... other then that I would think it would bolt up with no problems... the only other question would be the port timing which I belive is the same and then the intake runner where the manifold bolts on

 

So you're telling him to put a 6 port rear iron in a 4 port engine?

 

Yeah, just get a new S4 TII iron. They are a dime a dozen. I got tons for sale but too bad they cost a lot to ship.

 

No, no no. Are you serious? The biggest difference is that the na irons are 6 port, and the turbo ones are 4 port.

 

i got one
