Turbo/exhaust mani for my car

[JET]

I am starting to dive in to figuring out which turbo and exhaust manifold I am going to buy. I was going to make an exhaust manifold and still may, but time is tight right now. Price isn't a major concern, but cheaper is always better.

So far I am looking at a Shearer tubular manifold with Vband output to a 6262 BB in the ported S housing. The 6262 is a little bigger than I really need, I am only looking for 500 whp at DB. I doubt the spool of the 5862 would be much different though and their smaller exhaust wheels are not billet as far as I have seen. If the 5858 was a billet exhaust wheel I would probably go for that.

I am gearing my car to be a near daily driver and an all around car. I love a spool below 4k, but I should be around 4200 with this setup I think. Car is an 8.8:1 2.4, big cams, will have a SMIM, big IC and 3" IC piping, 3.5" exhaust running E85.

I have been looking at the Borg Warner turbos a bit too, but am leaning towards the 6262.

The 5858 has the new CEA exhaust wheel and is rated to 620, PTE seems to be rating their turbos conservatively these days as well.

If that is your true goal the 5858 should do that on corn, however shane did tune a SCM5857 on a 2.3, I think at 30psi it did 500whp on a dynojet, but you still have boost to play with.

I would go with the 6262 they perform very well. theres a laser running around that made 500 at db. Hes running a 6262 set up with mild bolt ons.

They changed that recently then? Their website says the 5858 has a CEA compressor, but regular turbine, as well as anything I could find online referring to it.

I'm "only" looking for 500whp hahahaha

For that power level, you don't need a tubular mani anymore, the FP cast mani and a Mitsu style turbine housing will do the trick with more reliability and less underhood heat. I was just having a few beers with Mike Rizzotti this week and he sold off his Shearer top mount and went back to the FP mani. He's still looking for around 600whp detuned. :D

I would call them and ask about what CEA exhaust wheels they have, I know they do a 5862 as well. I might of made a mistake about the 58 CEA being a turbine wheel, but I know I read somewhere they had it/coming out soon and that was a couple of months ago.


That would be if you really want to keep the response, but if I had to choose I'd do the 6262 but then you would probably have a 600whp capability if you wanted it.

If you do a FP mani, then for sure 6262, if T3 then maybe the 5858/5862

I had a PTE 5557 billet make around 480awhp my numbers with stock intake manifold.

Could choose the knockoff version of the Turbonetics(T3) cast mani I have. With E85 they are great, but on gas they'll boost creep into the upper 20's psi.

If you go the T3 route, this seems like a pretty sweet kit: http://www.maperformance.com/map-tubular-t3-turbo-exhaust-manifold-kit-dsm-map-dsm-tem.html
