Rb20 Turbo Manifold

[r3240sx]

I have a really good deal pending on an absolutely huge turbo... I'd rather not say what it is, because... well, I dont need anyone to tell me how slow this thing's gonna spool. Hahaa..

I'm looking for turbo manifold options as the exhaust flange is a t4. Its also an externally gated turbo. Is there any particular reason why fabricating a 3-4 inch spacer, that converts to t4 flange, and has a wastegate flange attatched to it, would be a bad idea?

I'm not too stoked about paying $1000+ usd for an aftermarket manifold just yet.. And I'm not very exited about that $100 ebay garbage... I'd like my stock manifold to work untill I can fab my own a little ways down the road..

Any suggestions?

Thanks dudes!

You can get a flange from t3 to t4 from horsepowerinabox.. but you might have trouble putting a massive turbo low mount if your planning to use your standard manifold ... what about 6boost? i read they're doin well in the HPI mag... custom manifolds and ones ready made... give em a go

Just checked em out.. Horsepowerinabox makes an internally gated t3 flanged manifold, and I didnt see a t3 to t4 adapter flange... Another problem I have is that the motor is in an s13, and I am unsure if their manifold would fit with my LHD steering column.

6boost's website is under construction.

Thanks for the suggestions!

try 6 boost but look at his thread on www.calaisturbo.com. I have one of his manifolds and they are awsome. there is also another guy on the same website that also does manifolds - all around the 1k mark.

Call Protechfabrication, He can make you a very strong manifold. What kind of manifold are you looking for? Equal length? Tubular non equal? Here are some pics of there work. He has made one manifold for the RB20/25 so far but it's not finished yet. Mostly SR20 manifolds that go on fwd car and awd cars like the GTiR. He is very happy with the amount of room we have with the 240's. Wayyyyyyyyyyyy more room than a fwd B13-B14. some more pics http://www.3rdgearvtec.net/Andys%20Videos/Protech/ http://www.3rdgearvtec.net/Protech/ The RB one he is making is about this thick .

Here is there web page with the contact info. http://www.protech-fabrication.com/

I've just been thinking today about manifold options and basically come to the conclusion that not only do I not want to pay $1000+ usd, but... what in the world would ever be sure to fit my application? LHD s13, very very large turbo, and still make for a reasonably shaped turbo elbow? Nothing! lol..

I think I'll be better off buying a decent welder and making a log manifold, DP, and the required IC piping.

Thanks for the help everyone

If all you want is a log then use the factory manifold. You can make an adapter box to put a bigger turbo on the car, tho it's not best way to make power but it will work.

im doing an rb25 manifold for a lhd silvia soon actually.

i have all the measurements.

if your interested i can show you some samples of my work
