So far manifold options for that sucker are few. Very few.

Welcome danduv, to the best site on the net!

If you want a ramhorn style manifold that will work with an EFR and retain AC/PS talk to abe at ARTech. I know he has a top mount that will work and I am fairly positive he has a bottom mount that will work too. I know I asked him about it in another thread and he said he would have to test it with an EFR to make sure but he said it should work.

FrankB is also putting an EFR on his stock motor and he went out and got the low boost wastegate which is 6psi, I believe, to be sure he did not vent the block. I for one say buy once. Always try to modify with your absolute end goal in mind so you don't have to redo your setup every time you get the itch for more power.

Exactly what I was thinking.

Any benefits to top or bottom mount? I think I am going this route.

I don't know what any of these acronyms mean - log mani, MS, fmic, etc – but I have enjoyed reading this thread very much. I find it amusing that this turbo thing has a complete language all its own and I am glad you guys know what it is!

I’m a bit on the old school side and never got past V8…:noob:

log mani = cast turbo manifold, ms = megasquirt, fmic = front mount intercooler.

I looked through your build, looks good man.

Bottom mounts are better for flow because of the downpipe path not having so many hard bends. The packaging for bottom mounts usually makes retaining AC/PS very difficult. They are also harder to work on.

Top mount manifolds sacrifice optimal flow for ease of packaging and maintenance. The turbo is very easy to get to in the engine bay and is clear from the AC/PS. This also places the turbo near some items in the engine bay that need to be protected from the heat including but not limited to the dipstick, fluid lines/resevoirs, etc.

Generally speaking, would it to safe to say a good top mount would still flow better than log?

For sure. Leaps and bounds better. They still flow very well, it is just not as optimal as a bottom mount. Most people around here with ramhorn manifolds run top mount for ease of packaging and access.
