Ok well im pondering what type manifold i should get. I definitely want the divided collector and the t3 but im not sure if i should get the forward facing or the center. Is it hard to keep your maf if you have the forward facing and is it too hard to run a downpipe with the center manifold?

This is Darius Foward mount manifold, I don't think the maf placement is a issue.

It fits but you can see that I had to remove the stock coolant reservoir, find a new tank that fit and then ghetto rig up an overflow line from the radiator.

Also with that setup, an Apexi filter is almost 100% necessary because other filters may not smooth the intake flow enough for the MAF to work properly. I'd recommend the center positioned unless you're having a huge turbo with 4-inch piping after the turbo.

well im gonna be doing 3.5" piping to match up with the rest of my exhaust. Heres my setup. I'll have to keep the stock crossover pipe for now. Do you think it will cause any problems?

Also make sure mine has a single gate on it as well. Im waiting on some opinions before i decide if im going with the forward mount. Will let you know today, soon.

Or go with a map system and the hell with the air filter j/kBut seriously the reason I went with forward placement if because of W/g and turbine clearance to the master cylinder. How much clearance do you have with the wastegate?

heh yeah and spend another $1000 on a d-jetro PFC or entirely different EMS.

If you go with the center-positioned manifold, you'll probably have to use 90's to go down and out for the downpipe. The forward-positioned allowed me to use custom 65* mandrel bends. There's a place in MA (mandrelbends.com) that will do anything you want for regular price!

The wastegate fits perfectly and it takes a little planning, but a 1.5" dump pipe can sneak between the steering shaft and frame rail to tie into the exhaust if you so desire. You need to be a bit of a contortionist to install it, but I'm sure you can manage it.

I think you may have to modify the stock intake pipe, I think with either manifold you will have clearance issues.

Well ive been lookin around and im gonna end up getting the plazmaman intake so that wont be a problem anymore. What do you guys honestly think. Would there be any real sacrifice in performance if i went with the center position and did 90's in the downpipe? i just know how tight it is trying to find a place for the maf to fit and i hate the hassle. Im gonna be taking my power steering out so all of that wont be in the way. I havent been using it anyway and its fine to me.

I guess you should follow darius advice and go with the center mount.

will 90's in the downpipe really hurt performance that much though? If not then put me on the list for the center position instead of the forward facing

As long as the 90s are mandrel 3-inch or larger, they will be plenty big for any of our power goals.

Is it too late to add more people? And do you think he'll ship to Canada? (I don't mind paying a little extra for shipping)

If so, I'll go with Forward mount twin scroll, t3 flanged, Single gated manifold. I can't pass up on an offer like this.

email: gegolick(at)ualberta(dot)ca -> just shoot me an email with the info

I can pay the deposit as soon as I get the paypal account to send it to (cause I know you want to do this asap).
