Sorry guys, long time since my last post over here! I hope to clear up a few things, and have responded to each thing via quote.

if not, what will be the biggest differences between the 2871 vs t3/t4 50 trim .63a/r?
Remeber there are two different 2871r turbos (.64 and the .86) and both are very differnet animals. I think the .64 housing IS the ultimate street turbo out there right now for our cars. Quick spool, great power potential, and no need to build the engine to high heavens to withstand it.
the AGP 50trim t3/t4 IMO is a better replacement for the gt2871r .86 housing. It has equal flow, and typically produces a teeny bit more top end power, at the cost of spool and low end torque.
With that said however, my setup is fantastic for HPDE, easily capable of an 11 second pass, and is just as fast as 500 whp Domestics on the street. Having the easy of install of the t2, using stock stuff like the t2, and having more grunt are all huge advantages over the top mount t3/t4 (and all of the issues assocaited with them)

If price is a cocnern, moding cars shouldn't be your hobby. Not meant to be rude, just my opinion. You don't buy cheap 25 cent condoms do you? Same should be said with automotive part purchases.

Tubular manifolds HURT spool, not help. They do sometimes offer higher top end HP potential, but in this case, no one can prove that they do. Plus who wants the worry of 'when will mine crack' with a tubular

I just recentl put in a 4.6 diff (wow awesome....and affordable if you use an Xterra SE front diff as the doner)
Wheels are Z33 Ray's 18's (track edition wheels), on 245/40 Federal 595's in the back. (225/40 Hankook Ventus RS2 in the front)

Things I'd change:
Dump the HKS cams in favor of Jim Wolf S3's. This will also elimate need for all of that other BC chinese crap in the valvetrain, just waiting to fail.
I would also not bother with the MR tubular at all. Extrude the stocker, and coat the stocker.
I wouldn't use the MR o2 outlet either. Use the greddy. Much better design, no splitting issues.
Can't say anything about the Tomei HG, but I strongly prefer the ApexI

Ex XS, now Cosworth GURU Eric Hsu did claim that, but never showed any other examples. HOWEVER I have no doubt in his claims. To use a line from his blog, he certainly builds 'buff' cars.

I ran cam gears in the car, as per direction of some OG FWD sr guys, and noticed much less top end then I liked, with only a minimal gain in the torque department. Granted all *** dyno, but I believe mine to be pretty calibrated. No difference in daily drivability either. JWT cams rock rock rock right out of the box.
External gate should theoretically enable more HP potential, but gains sometimes aren't seen in the 'peak', but moreso in the 'overall', or total area under the curve. I will be upgrading this over the winter.
And Meth rocks. My JWT ecu has it programmed in, but I will finally be installing it this winter as well.
SRspoolin wrote:so whats the deal with hybrid turbo's? whats good about em and not so good?
Hybrid is an old term we used to use when all the rage was sticking to4b compressor covers on our t3's haha. Every turbo is essentially a hybrid in this day in age, unless they claim 'straight t3' or 'straight t4'

They def make nice stuff, but I can't say for sure they work with JWT ecus. JWT offers OEM Cobra MAF (90's Fox body MAF cobra) and 90mm Lightning MAF support.
