How well do the SR20DET downpipes work with the RB25's in an S14? I'm having a little rubbing of the turbo elbow on the steering shaft and read most people get custom one made or use spacers, but I found this 1 piece elbow/downpipe for an SR20DET on Ebay and was thinking of trying it out. It looks as if it may clear. http://cgi.ebay.com/ebaymotors...QrdZ1

You think it would be hard to just cut that one off and weld on a T3 flange? I guess I might as well just make a custom.

the "t3" flange is on the manifold

you need one for a rb (6 bolt).

just go custom.

I thought the T3 dishcarge flange was a 5 bolt?

it can vary by the turbo. some are 4 bolt, 5 bolt, Vband, etc.

but the RB's is a 6 bolt. so you are gonna have to go custom.

get hold of bronze mfp on this forum, he got a really nice dump tube from a guy in au which converts the turbo to external gate and allows for mad steering clearance...the first version he got from the guy had to be hacked up but the current on his car roxorz hard, fits very well and sounds evil.

so it would work on a stock turbo? Does it just split the exhuast housing into two sections and the turbine wheel goes to exhuast and the internal wastegate flap has its own pipe as well?

yare.bolts right on to the stock turbo and doesnt split the turbo off but rather seals the exh wheel outlet off completely from the wastegate bit.its a very good design imho and for the 140ish usd the guy charges its well worth the money for those ppl who dont want the cast elbow to rub the steering linkage.besides the external gate bit sounds right nasty, we'll have to get some video of it.

I am highly interested, considering my RB25 elbow rubs like crazy.

Im about to pull my RB25 out and bang out the firewall a tad more, replace the flywheel and toss in a kevlar coated clutch, as well as go and find the source of my boost leak on my intake manifold, so while im taking it all apart ill see if i cant get ahold of Bronze MFP and source out that pipe, it'd make things with the steering shaft and steering rack easier to adjust.
