'89 Silverado RCSB 2wd LQ4/4L80e/76mm turbo build

[LS1FREEK]

Stock driveshaft with 80e and 1" back TransDapt plates



Stock shift linkage needs to be shortened about 1"-1.5" and it should work fine

Well I got the beast running last night!!! Got a small water leak by the thermostat and a small leak by the PS pump fitting, otherwise sounds good. But the big problem I ran into is fueling, I had the tune set at 108# injectors, which is what mine are @ 58psi, and I fired it up and it would run for about 2 seconds and die. I finally got it to run long enough to where my wideband heater warmed up and the AFR was peaked out at 17 AFR, so I moved my injector flow rate down to 95# and it idled real good but AFR was still peaked at 17 AFR and if you'd hit the throttle a little it would just want to die. I'm gonna put a fuel pressure gauge on tonight after work and see if mabe the stock FPR is shot... IDK what else it could be?? Ideas??

Well turns out the Bosh 044 in-line pumps dont really work well for gravity feed situations (or so I've been reading) although I took my pre-pump filter out and now it works, kinda for about 15 mins, I can at least drive it around for a little lol. Got a new Walbro 255 with high flow fittings from Glenns Performance on the way,and in the near future I'll have a second one on the way too lol. In the mean time here's a little teaser video lol

First off, the reason the front fender looks that way is because my brother owned the truck before I did and he was planning on repainting it, and he started sanding LOL, and the intake off the turbo, yes I know is very restrictive, but is also temporary. I just put together what I had in the shop LOL

The intake isnt so much restrictive as it is just drawing in hot ass air with the filter being so close to the down pipe and hot parts.
