Hahaha... gotta love 105 octain fuel. Not a huge fan of that gen camaro but I give respect to anything laying down those kinds of numbers.

New to boating, but know this one since years.
This I believe could be a "gold mine" for anyone wanting to convert a GM truck/car engine for marine use. WARNING 60+ Megs http://www.chevroletperformance.com/...CP_Catalog.pdf |
Hell yes thats a good piece of information right there
|
so i figured I'd bring this thread back to life a little. if anyone has any additional information that would be greatly appreciated.
|
Checking in for info and will detail a project I'm working on soon. Sweet 16 Donzi, ls1 with a bravo.

I'm getting ready to Send my lq4 off to the machine shop sadly I have to wait to install til spring. But I think this engine platform is finally going to take off in the marine world.
|
I think the power these things make is unreal for what little needed to do...cost of parts still pricey but hopefully come down as more people start making parts...
|
Yeah its not cheap. Yes I could just stuff a junk yard motor in and go but what fun is that? :D. So just some more info on the what's needed. If you decide to run speed density, no maf, then you need an iat sensor installed some where. I'm putting mine in my egr plug in the intake manifold. The ideal iat to use is one from a 92-93 gmc typhoon as it has 3/8 npt so you can tap the egr plug for it. The fun part of the entire swap is the harness. I gutted mine and rebuilt it. Major advise tho... make sure to lable every pin as you re move them from the ecu. And major and here plug in all your sensors you are keeping before you start pulling wires. That way you know what is going where. Then you can lay out your harness any way you like. This will save you major time trying to read 20 pages of wiring diagrams. Then if you have doubts check your diagrams. The maf on most has the iat built in so you will have to cut those two wires from the maf plug and hook up a two pin connector to make it work. You will need. The connector for that sensor as well.

I think running a megasquirt II would be the way to go...tune from a laptop and run what inputs you need...run that in racecar(a III because do much more than needed in a boat) and a II in our boat with our own EFI BB w/procharger
