Soooo, which manifolds work with a R85 turbo, and an EFR8474? I worry about the R85 fitment because of it's huge hot side. I believe the R85 is a modified s300 series with a 1.15ar
I was planning on using an EFR8474 IWG with a turblown shorty manifold in order to retain my air pump for emissions... well, I no longer need to do emissions, so I figured I should probably just use the r85 that I've had sitting around for a few years to keep cost down.
I'm still thinking about going with the EFR in the future, so what manifolds will work with both? I'll likely stick with EWGs so that I only have to buy one manifold that will last me for ever hopefully.

I'm running a half-bridge ported motor with non-sequential twins at the moment, and it's really annoying having to limit my revs to 5k due to the back pressure.
Thanks in advance

 

We just pulled an R85 off a car actually.... it uses what we called a T5 flange. Not quite a t6 and not at all a t4. Its unique. So no manifold would be compatible with both..... which we found out the hardest way possible.

 

Wellllll ****. I could have sworn it was a t4. Who makes the manifold that was on that car?

 

no idea. his car was built back in 06 and remained mostly dormant for that time. he bought the turbo and manifold used back then from someone. so he wouldn't know. we tried really hard to mod the flange on the R maniold for a t4 to bolt to and after the holes were slotted enough for that to happen, the turbo didnt fit lol. the wild snail shell shape of the R back housing forces the manifold to sling the body so far into the chassis that an average sized back housing just doesnt work. it hits the car. he still have the manifold if you want it. its not bad, just old.

 

Go figure!
Yeah, I think for now to save some money on not buying a whole new setup yet, if I can get ahold of his manifold I'll take it. Let me know!
Thanks!
