my turbo build

collecting parts to go efi, so far I have the harness, injectors, fuel rail, and lower manifold. I still need to make a upper manifold similar to jims junkyard efi system, a mass airflow meter, ecu, and throttle body.

started sorting the harness out to thin it down.

while it was out I also installed a exedy hd clutch kit, walbo 255 intank pump, and all new fuel injection rubber hoses. I will get a video of everything running in a few days.

Glad to see you decided to go EFI man. Looking good I can't wait to see this thing running! I have been tossing the idea of rebuilding my 2.2 and converting to EFI to run boost as well, but am uncertain if the overall outcome will be worth the time and money spent.

ill let you know what I think about it in the next few days, I really hope it was worth the conversion.

Awesome thanks man! I'm sure will notice quite the difference in an FI turbo set up verses the blow through set up. Way more efficient and a lot more tuning capabilities.

im still researching on tuning the n/a ecu, almost all the info is for the turbo ecu. im going to do a VAF hack to tune the a/f mixture but from what ive read it will only go so far. im using b2600 326cc injectors but I would eventually like to go bigger probably to rx7 440cc's.

finally got to drive it today. so far im very pleased with the EFI swap it seems to have so much better throttle response and even more useable power. im still tuning the MAF and fuel pressure to get it just right. here is where I left off for today. should have videos in a few days

I cant figure out how to embed the video, but here is a link to the truck running. I will get some better ones soon.

Looks great bro and sounds healthy! It looks like it it belongs there. Get that thing broken in, change that oil, then see what it can really do....after you get it tuned of course

it is so quite now with the new lifters and the loud ass carb gone. I almost thought something was wrong it was so quite and smooth
