That's an easy question, PF is right around the corner.

SFR stuff is so nice though, that's how you're supposed to do a TT. Just look at the manifolds! There's only one thing that makes the TT kit unappealing. It's the oil return setup, something that can't be avoided, but just makes things a little more complicated.

Here is a handful of the 200+ builds/tunes/cars we have done. All the shops mentioned and great shops. I would take some time, and call them up and see which one offers the services and package you need, and if possible, make a visit to their respective shops before taking your car in.

yeah.. def liked alot of the cars.. sorry if this is off subject but how bad are the stock heads and intake manifold? im really starting to like the cosworth manifold, just wanna make sure its worth it.. also im wanting to have the heads done over with a mild set up.. like port polish and a nice angle put on it.. would that be ok? or a waste?

If you are going to run low boost or are going naturally aspirated, the Motordyne 5/16" plenum spacer seems to be the best bang for the buck on a VQ35DE motor. For the rev-up motor, you probably should consider the Motordyne MREV 2 intake plenum and the 5/16" spacer.

For a moderate to high boost application you may want to consider the Cosworth intake plenum. It is my understanding that it will add 20-40 hp at high boost.

The VQ heads are already very good from the factory. It is debatable whether it is worth doing any porting or polishing, and you will hear different opinions depending on who you talk to. Unfortunately, I was not able to find any dyno comparisons, but there are guys claiming well over 600 hp with stock heads. If you are on a tight budget, you are probably better off putting the money elsewhere.

On my build, I am running a 2.5" APS exhaust system to keep the sound of the exhaust down to a reasonable volume level, although I know I will not get as much boost out of the turbos as I would with a larger exhaust. With that in mind, I am looking to squeek out any additional hp that may be available elsewhere. I therefore had the exhaust ports matched to the exhaust manifolds and I had the intake and exhaust ports polished to remove any casting imperfections (although I have been told they are minimal). That said, I did so knowing the hp gain would not be much and I got a pretty good deal on the head work.

If you are going to port and polish, I would also match the intake ports to the plenum intake runners.

I have not yet receiived my Cosworth intake plenum, and I have no idea when it will arrive, so I was not able to do so without holding up the build indefinitely. If you plan on using the Cosworth intake plenum, I would strongly recommend that you order it now. Perhaps by the time your ready to do your head work you will have it in hand. In my situation, I'm left with hoping the intake runners closely match the intake ports.

Here is a Cosworth plenum test we did on a smaller TT kit...this one was the PE TT kit. http://my350z.com/forum/shop-builds/...lthys-car.html

Nice dyno comparison. I really like the ~35-40 hp gain at 3000 rpm too.
I edited my reply above to indicate "moderate to high boost" instead of "high boost" application for the Cosworth Plenum. Now, if mine would only get here...

Sharif, how well do the Cosworth intake runners match to stock intake ports?
