My 5.3Ls blow threw Turbo 240sx build

[Sleeper101]

Well ive not been on here in a while. I sold my rb setup thank goodness and I decided to buy the chevy ls 5.3, then i decided to add my 60mm precision turbo + a blow threw carb setup. Im tired of dealing with wiring and fuel injection for a while. So im trying something new.

Motor came out of a 2000 Suburban, Not sure of the mileage.

I got it stripped and started the mock up on the turbo + headers


The turbo headers I bought were godspeed and were for a 2000 camaro
Gto oil pan
ls1 eldebrock victor jr carb intake
Spector turbo hat
Holley 650 double pumper blow threw carb
Aeromotive fuel pump + frp


I also had to modify the front core support, the radiator was never going to clear the turbo So i relocated the radiator and it now sets like a camaro with a slant.

I got the engine bay all cleaned back up and re-painted


I had to notch the frame for the turbo exhaust to fit


I had to notch the core support crossover for the radiator hose to clear in its new location


I had to notch the crossmember for the gto oil pan to clear and set back as low and far as possible


I bought transdapt motor mounts, they weld to your frame. I had to modify them just a little and cut them a little shorter, but they worked out great.

Bought the Redneck performance 2spd powerglide with 3500 stall + transbrake


I used the nissan alternator and made a custom bracket


turbo and radiator clearance = TIGHT! but works


my exhaust routed


wastegate installed


I took a q45 differential and took the ring n pinion out of it 3.54 gear ratio and i put it in my stock r200 case (factory 4.08) so now i will have a final gear of 3.54, should help load my turbo more.

and here is the most recent photo's got the intercooler piping welded up





I have not fired the car up yet, still gotta weld some fittings in my gas tank + run my gas lines, I still need my msd timing controller and a few other nic nacks, but it should be fired up within a month.

enjoy and to anyone who wants a build similar hope ur good at fabricating, ive spent the last 8 months making it all fit and work.

Well over the weekend I got my electric fans wired up, line lock wired, starter wired, water pump on and wired, intercooler pump wired, radiator hoses sorted out, transmission cooler installed, and hard lines ran, new fuel rail in and plumbed to the fpr. Got the fpr mounted, and fuel gauge installed.

So I'm basically down to putting the fittings in my fuel tank, running my feed and return lines, msd install, shifter, intercooler ice box, and a few other nic nacks, hope to fire it up within a few weeks.
