    I have a 1994 Full Size Chevy Blazer that I have had for years. I keep it to pull my toys around. It has a 393 in it, 8.7:1 Compression, World Product S/R Torguer heads, small Lunati Voodo cam. It was TBI, but I converted it to MPFI. I would like to boost it, but I want to build boost early for lots of low end. 10 lbs max. I don't car if it even revs past 4500-5000 RPM.

    I helped a friend put a turbo off a 6.5 GM Diesel on a Ford 300 6 Cylinder and it worked out great for him. He has 2 more these Borg Warner GM-4 turbos I could use but don't know if 2 would build boost as early as I like. These turbos look small on the compressor side. Looking for some pointers on a single or twin setup that would work.

    I would use a single BW s366 with a 2" crossover and 1.5" headers. dont oversize the charge piping either, 2.5" would be plenty large.

    Thanks for the reply, I have been doing a lot of research. What about a Borg Warner s476?

    Actually, I think this is the Turbo you mentioned, looks Good too and should build boost quick
