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 ,y 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.
Image

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

The headers I bought were godspeed and were for a 2000 camaro
Image

I had to modify the crossover pipe for it to clear my steering shaft.
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.
Image

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

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

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

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

I bought these 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.
Image

Gto oil pan fitted
Image

Bought the eldebrock victor jr carb intake
Image

Spector turbo hat
Image

Aeromotive fuel pump + frp
Image
Image

Got the oil return welded into the oilpan
Image
Image

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

Got the motor in and bolted up
Image

I used the nissan alternator and made a custom bracket
Image

turbo and radiator clearance = TIGHT! but works
Image
Image

my exhaust routed
Image

wastegate installed
Image

Transmisssion crossmember built
Image

Holley 650 double pumper setup for a blow threw turbo, custom floats + metering blocks etc
Image

taylor 10.4mm race wires
Image

ls1 electric water pump
Image

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.
Image

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

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 :naughty: hope ur good at fabricating, ive spent the last 8 months making it all fit and work.

that thing looks wicked... only thing though is will the turbo hit the radiator if the motor rocks???
and what are you doing for a fuel tank to run that pump.. stock or fuel cell?

I am going to use the stock fuel tank, we built a pickup tube inside the sump for a #10 feed and were welding #8 return into it.

With the transdapt biscuit mounts it only allows the motor to flex about 1/4 inch, so I shouldn't have any problems.

Well after several months of struggling, junk yard motor turned out to be junk, so I built a new motor. Its a 5.3 iron block, punched .110 over, scat h-beam rods, je forged pistons, arp everything, comp cam .614 lift, comp valve springs etc. Finally got the motor in and running, now I just gotta work out the bugs and get it to the dyno. this car has so much tq there is no comparing to any nissan motor. So far I'm enjoying the new setup.

Nice work! I'm working on an S13 coupe drag build, with a VH45DE, single turbo.

I noticed that turbo oil drainback is practically horizontal...are you relying on G forces under acceleration to assist in drainback?

The oil return is close but it does set above the drain a few inches. It works great, no issue's @ all.

I have not really updated this thread in a while. Build is pretty much finished with some small tweaking. I've been making some track passes tuning the suspension in. The car dyno'd a few months back @ 486hp and 490lb tq. So far the best pass is 6.60@ 109mph with 1.50 60ft

Here is a few video's of me doing some testing a few weeks ago.


I upped the 2step to 3600 on this launch, only got a half track pass, my dash gauges popped out and hit my fuel pump switch shutting the car down.
