Thread: Prototype Turbo Manifold

Glad to see someone producing that style of manifold again. Since Lovefab isn't supporting our community anymore, I am glad to see Javier taking the time to implement good designs and provide solid products to the community.

I would've gotten one, if Javier started it a week before he did!

Final pics installed? Looks really good.

How much for this manifold man?

Finally put on the prototype manifold tonight.....it looks sweet!!!!..definitely needing to modify the thermostat housing and distributor....but overall.....fit and finish is excellent.

also did a before and after dyno run......of which i gain 40.03whp and 25.95lbft torque.....also turbo spool at approximately 500rpm quicker

U had to modify the dizzy?? Pics of your install please.

Thanks!



$750



Very nice! I'm working on the cooling line parts. I should have something machined and prototyped by next weekend.



Hmm...what did you have to modify on the distributor? I'm wondering if the Precision turbo placement is a little bit different than the Garretts. I can adjust the turbine flange a little to fit Precisions if this is the case.

due to the size of the precision turbo and the mere fact that the distributor i'm using is of the older type of which is wider than that of the G20 use for mocking up......had to shave off the screw area off it(distributor)
The car feels great and spools fast,


thanks a million again and again!!!!!!

What size piping on that manifold? Also that is stainless correct? I'll be sending you an email in a few with my requirements so that I can get a price quote.

No problem, "enjoy the ride"

In the future, If I can get my hands on a Precision Turbo, I can tweak the fixturing and make sure everything fits perfect.



The piping is schedule 40 1.25 (ID=1.4") 304L stainless steel. From my experience, 1.25 scheduled 40 is a good choice for T3 framed turbos...even the newer units that are supporting 700+hp. The 0.5" flanges are milled from 1018 cold rolled steel. Everything is TIG welded and back purged.

-Precision 6262 T3 framed turbo
-Wolf V500 engine management
-TurboFX SR20 T3 manifold w/ 44mm wastegate flange

These are dyno runs of the car with the previous log style manifold setup vs the new tubular manifold setup. Both runs were at 20 psi on 93 octane. The tune on both runs was identical. Once the tune is dialed in for the new setup, I'm sure he will free up some more trq/hp
