If anything it will add power and it will be safer under boost at the cost of, well, being a possible pain to plumb everything up/ more system complexity. I wouldn't use just one 300zx intercooler if one 3.0 turbo car needed 2 of them, especially considering most stock stuff is fairly restrictive. I know you bought a turbo already but a really good one would be an HX35 off a cummins, some 5.0 ford guys use them and they say they are a bit on the small side for a higher revving 5.0 so I figure it would work VERY well on a 4.9 in its power range. BTW a diesel turbo usually has a large turbine housing compared to its compressor housing since diesel's apperently have more exhasut energy than gas engines so thats something to consider when using a diesel tubo on a gas engine. If nothing else before ensuing any further into the project get the most helpful turbo book EVER in existance by Corky Bell "Maximum Boost" I found it EXtremely helpful. Good luck.... |
Thanks for the input dude
Right now the project is at a standstill due to time constraints and such, but hopefully this summer things will pick up a bit. Maybe a little sooner than that.
As for an intercooler, I would just feel better having one, so there is no real biggie in terms of where I am going to place it at and the plumbing associated with it. At the junk yard a few weeks ago I seen a nice intercooler from a Saab, but alas it was too large for where I have plans to put one at.
My biggest concern remains fuel: I simply don't have the confidence in what system I want to run. One thing for sure is that it will be an auxiliary piggy-back system running along side the stock system. I am getting mixed signals from people as to what a piggy-back system will do when ran in conjunction with the stock system...
I have one person hoping that I will choke on Rotella diesel oil (presumably) on this project telling me all kinds of horror stories, so I am a little concerned on how to run this extra fuel without blowing something.
