Have a job on a ZZ4 engine. The owner wants a FI on his ZZ4 and looking for the best FI set up that will work the best for this engine. Any help will be good.
I suggest a Speed Density TPI with a custom chip from Street & Performace.
Thanks for anyones help. _________________ Thanks

What would be the purpose of the engine, everyday normal use, all out racing, or something in between? I'm kind of partial to the Holley Commander 950 multi point injection system, but will probably settle on the Commander 950 TBI system because of costs for my Elky. I have a GM TPI system on my 88 GTA, it's alright but limits you on what you can do performance wise. I'm not a FI guru by any means...if I have to modify and adapt something, I'll admit that I'm lost, but I can follow instructions and I picked the Holley 950 for ease of installation/performance gains. I'm one of those plug and play guys. _________________ "The day we lose our will to fight is the day we lose our freedom" http://www.youtube.com/watch?v=TG4fe9GlWS8

If your going with a TPI setup i'd upgrade the hell out of it. TPIs make great lowend torque but the powerband dissapears after 4500rpm. I'm thinking the best bet would either be a stealth ram. Thats of course if he doesn't care about money.
Superram is another option.
Its spendy as well. Like $3,000 with the ECU and harness.
Theres a great article on the different aftermarket TPI units
