For a bare bones approach, CZAR already detailed it out. For the turbo choice, I lean towards a standard Z31 T3. For 10:1 compression, I don't know if the more expensive T3/T4 is justified. But not that it's not possible! Just that an IC would be certainly be needed to take full advantage of the bigger compressor housing? For now, I would add that a JWT ecu program would also be strongly suggested(w/ the T3/T4) For just the T3, just use the Vortech FPR and a larger capacity fuel pump. CZAR experienced some bad running in the dead of summer(worse case situation). I suspect that if used the FPR, it might have aleviated alot of the problems(but to what extend, I have no idea) Whan I ran his exact setup, I could stand on it "fairly" well. Even a VERY short wot. But what was in the winter(best case sitiuation but still no fpr). I didn't see any pinging etc. But we are talking a good 40 degree ambient temp diff. Also like having/not having an IC. : Basically I was asking incase I decide to go that route to make sure I'm heading down the right path. Like many others I consider myself a DIY's and do research before hacking. Unfortunately I don't know of a source for thicker head gaskets, but with proper fueling the higher compression ratio might not be a issue. I also figure a lower cr would help for a happy and long life with force induction. Custom making a "money" piece is no problem, besides as stated I have a auto. What material did you guys use to fabricate the money piece, is ss? What does it include, is it a 3, 2 or 1 piece set? Just a little more info needed. I may consider it since it would help lower the countless hours begins a welding shield. I agree, use 3rd gener's have more flexability with fueling, hell we can retard our timing with basic hand tools and no fancy high dollar electronics. I'll even answer my own question : 1)I would lower my cr, but I can't help to wonder what 10psi and 10:1 cr would feel like, all dependent on proper tuning : 2)Keep stock ECU and injectors for better everday driveability and go with 2 extra inj from a seprate set-up for high boost situation. Of course all the usuall fuel pump upgrade and fpr : 3)Of course : 4)T-3 family with a super-60 compressor trim and 72 turbine wheel with a .42 a/r for quicker spooling. Since it will be a everyday driver who am I fooling with a larger a/r and we all know how VE autos suffer down low. : 5)100-150 hp on those cooler days, what ever boost I can safely run without destroying the engine : 6)Personally I'll go with a wet housing, even though it takes extra coolant piping. A wet housing will help during the warm down time especially after shuting of the engine, the warmer coolant will help prevent the oil within the bearing housing : 7)Why not
Mike there are probably 4-5 different ways to turbo a V6. If you want to custom fabricate your own x-over system, I can only say unless you are a very experienced welder, I don't recommend it(at least for the way Matt and I have it(orignal design by CZAR) CZAR had a great idea and was able to fab a manifold but in all honesty, it wasn't a reliable or long term solution. But it did make for a great prototype. The shop we subcontracted the work to, even had their fair share of design problems. If you wanted to make your own intake charge/down pipe stuff, I would say that is fine. But the manifold/x-over should really be purchased from us. How much? We have to work it out still but not that much.
