Hi, I was just wondering if the b18 turbo cast iron manifold that they sell on ebay good for 400 whp? Any help??

 

donno man, but i was told I couldnt make over 500 on a log and we have. So ide say its all up to the tuner, and you as well as how far your willing to push it

 

I run one, tight fit on wastegate, i did 319 on 15psi. 81.5 mm ls block at 9.0.1. Car had full 2.5 in exhaust with 2.5 inch down pipe. Stock b16 head wiht springs and retainers. S300 tuned by stickerguy. If you run a good turbo, unlike me and have a cutout with a few more things done ie, cams. You should be able to pull 400 out of it. What are the specs on oyur build?

Good luck

 

It's a ls/vtec stock bore with wiseco flat top pistons and eagle rods.
Head is stock except for titanium retainers and valve springs, gsr cams.

 

lol if i can do it easily out of a dseries, i dont see a problem making it with a bseries

 

I run spring and retainers as well turn 8500. You should be able to pull it or close, 350 on the street is wild. What shell, crx? Good luck def get a cutout, i had a buddy here ake 58 whp on the same tune with open dp instead of closed on a turbo gsr

cheers

 

It will be easier to make HP with a nice ramhorn/etc, but a log can still make tons of HP. I know some people have made over 500 on cast manifolds, you just need to get a couple decent parts/turbo into the motor to get there. If you went with a lower CR ratio, you could really crank the boost to get your power goal - thats how most people make big power. 10:1 CR is for people who want to race off idle IMO.

 

If its a meutek or inilne pro then yes, i would bet even the spa cast topmount could do it too, but with the drag/revhard style its gonna be hard.

 

I made over 400 with a pfab man @17psi on a t3/t3 66 trim on 91 octane. Manifold isnt overly expensive either, and a tial 38mm gate.
You can acheive what you want with research, good parts, and a great tuner

 

so your saying you cant make over 400 with a drag manifold

 

If your talking to someone specific you should quote them but i will assume your talking to me, and no that's not what i said, i think i was pretty clear in what i said.

 

i made 420 to the wheels on a rev hard cast mani..so it can be done

 

I have a revhard log mani for suposedly a B16A2 but it is impossible to fit my Garrett T3/T4 stage 2 turbo and it makes contact with the block not only the webbing but the flywheel housing as well any of you guys had any similar problems?

 

a/c version or non-a/c version? The non a/c version flows A LOT!! I have seen north of 600 out of the non a/c.

A Garrett t3/t4 will not fit, you will have to use a 5bolt precision or turbonetics.

 

so doeas anyone know what manifold could i use to fit the Garrett T3/T4 on my EK4 with A/C?

 

I have a full ac friendly kit if you want

 

Yes, cars are making 800hp plus.

 

SPA topmount ftw. flows like a tubular, im running one with a/c and p/s and ive run tubular ramhorn and topmount before, and real ones not some ebay junk and it performs just as well as those tubulars. especially for a DD. i mean obviously if you were going for raw power then you wouldnt be trying to keep a/c anyway it would be a topmoutn twinscroll with a borg s370 with an r cover LOL

 

On an ebay cast manifold?

 

i dont think so, on a sap or inline then yeah, didnt someone have an inlin pro cast t4 manifold running 9's i forget who.

 

Matt keller, Andrea Evans

 

yes Evans crx ran 9's on an inline pro cast mani

 

Similar enough yes.

 

pics of said manifold? I'm guessing it was heavily ported?

 

mine is a non ac rev hard
