Hey all.Initially, when at the end of the build to the 5 oh, I was thinking of uprating the injectors,(pump I'm doing anyway) a 2 bar map and either a V2 sq or preferrably a V1 T trim/FMIC, but l8ly, I've been looking in2 turbos and need abit of insight as to what to look 4 in 1, be it single gt35/40, or a to4b splitpulse rear? I think I've got the a/r choice pretty much on the mark(.63 in/1.06exh?) but I really need some1 who actually knows what they're talking about to steer me in the right direction, so I can make an educated decision....:)

let me get this right, you have a 5L and you want to turbo charge it,

you want a T04z with a 1.15 rear housing as a minimium,

gt42 with a 1.05 as the ideal,

A TO4Z? Yeah, I think it's the 1.16 exhaust I need isn't it?(is that so the turbo's spooled up at the right rev range?-about 2500?) That's what I was told anyway, not that I fully understood why....
Is a TO4B too small on the intake as opposed to the Z?

Yeah, well I spose thats the main problem is just getting the exhaust manifold/dump pipe made to suit the 5 litre 4 starters, isn't it.
If only that could be done a lot cheaper, then again, I also like the set ups they do behind the diffs with the turbs aswell???
Thinking out loud here, has any1 ever set up up turbos' in series on the3 same exhaust bank, 1 after the other, or wouldn't that work?
