I talked to yenkoz28 about a couple of weeks ago. He's got about 20 K on it know and is not running a inter cooler. It
is cruising along about 80 on the interstate with no bogging down.

I would love to have that kind of performance on one of my first gens..

Hello Yenkoz28! Would you be willing to share your MegaSquirt tune? It would be a great help to my RS project and it will inspire others to go with the MS ECU. This could kickstart a cooperative sub-community of Trooper owners who continue to develop, refine and improve the performance of our venerable 2.6 4ze1.

Cheers,
Chris R

Looks like megasquirt has discontinued the one used here. Anyone know of something else?

You might try going to the Facebook page “ Isuzu 4Z Engines”.
Mostly an Aussie forum and the folks there tend to some pretty radical mods with turbo setups on 4ZE1 motors in their Gemini’s and Piazzas.
I’m sure if you asked what controllers they run you’ll get some good input.

You can wire a ms2 in. It just wont plug into the factory harness like mine did.

So I bought a Isuzu p-up and I was thinking about turbo charging it. And my brother brought up the impulse and said to just take everything off of the top of the motor and send the ecu to somewhere where is can get chipped for it. Where would be a good place to go and get that done and also I was having problems with finding aftermarket parts for it because I want to fully build it. I'm new here, my name is thomas. But I'm all ears to anything

If you could find an impulse 86-87 turbo and all the components you are set to go. You don't need to upgrade the computer "chip" since the turbo is small and produce about 8-10 lbs of boost roughly 50 hp. There is an Impulse for sale in Minnesota for $400, been setting for a while. I believed It is in one of the Isuzu forum in Facebook. Go to planetisuzu website, there is a good article on it.

This build is awesome! I finally have a turbo manifold on the way and am in the process of making a conversion plug for the factory harness to plug into my mega squirt. Could you send me your tune file? That would help a lot with me getting started. This is my second turbo mega squirt project, first one was an 84 Nissan 200sx. You mentioned you are using 55lbs injectors, do you remember what vehicle they were off of? Also, are you using an adjustable fuel pressure regulator? And if so, do you remember what you have your fuel pressure set at?

Thanks! -Matt

I'll need your email to send you the writeup and tune. I bought the 55lb/hr injectors new online, I believe the first gen DSM injectors will work but it's been awhile so you better double check. And I am just using the stock fuel pressure regulator since it already varies pressure based on manifold pressure.
