lumpy Forums Junkie Location: Adelaide, SA Registered: May 2002	Re: Turbo manifold design Fri, 07 May 2004 05:37 Leigh since you have a manifold already (bit rudimentry but workable), and a flange for a mazda series 5 exhaust housing I'd suggest doing what Sean and I had planned for that mainfold - clean up the ports, weld in a split pulse divider (S5 housing is split-pulse) and weld the S5 flange onto the existing CT26 one. Mazda Series 5 turbos are cheap, have a BIG exhaust housing that is still internally wastegated and can be rebuilt with T04 parts fairly cheaply (for a turbo anyway...). As long as you don't get one with a back-cut exhaust wheel the response should be good and you can fit a T04 front cover and compressor wheel on them. You can find them pretty cheaply on the ausrotary forums. It'll have more lag than the twins, but with the right exhaust wheel probably less than a CT26, and far more opportunity for flow at the top end. I actually bought a near new hybridised turbo with this setup (but a ford sierra turbine wheel) rated at 500-600Hp but sold it as I'm selling my car. This turbo is now on a 250 ford motor and boosts almost off-idle. Cheers, Caelum [Report message to a moderator]
