3500 5 speed turbo build

_HeC_ · 04-01-2016, 01:22 AM

Thought I'd share my build over here

just a quick catch up, I have a 2003 Grand Am GT that I swapped a 3500/5spd into last year with some bolt on's. Put over 15,000kms on that setup

Bit of a budget build so using 2 front LX9(3500) manifolds with a custom crossover and a Borg Warner S300 turbo from a 7L CAT machine, I had bought a turbo crossover fabbed up for a 2nd gen J-body with a flipped UIM for dirt cheap which didn't work at all lol

so grabbed a new turbo flange and pretty much started over trying to hug the engine as close as I could to make way for a 3" downpipe

The red transmission cap should give you a good reference point for how much it moved

Got the turbo mounted and did a quick mock up, happy with how things are going so far but still lots to do before May...

Dropped my turbo off at Re-Speed to get the turbo outlet flange changed to a normal 3" V-band

All mocked up

better view of how its all plumbed and getting it welded up

all done except for wastegate placement

3" turbo back, charge pipes, and wastegate plumbing arrived as well as my intercooler

Was hoping to get the DP passed the subframe but I couldn't remove/install it if it was any longer then what it is now

looking good Mike! Guess that means you won't make the season opener in Whitby on April 10th... I'm thinking of going down for it...

Thanks guys and what season opener Tim? Obviously I'm no where near driving yet lol but hoping to be burning rubber May long weekend!

I'll send you the link through Facebook... Used to be run by the gmco club but he folded it a year or so and another club took over the meets... It's held at the landmark cinema in Whitby at Thickson rd and the 401... Starts at like 5pm or sobering like that haha!

TCE 1.25" phenolic intake spacers

Hood didn't close

lol

the culprit

will clean this up later

mounted my intercooler as high as it would go between the crash bar...

this bump was getting in the way of going higher

much better!

charge pipes!

Did you get this build finished? Because this is awesome.

What was the power like before with the NA 3500 and 5-speed?

tw0123 · 07-10-2016, 12:23 PM

He's almost done... I'm bugging him to finish it by the end of July to bring it to the mini meet we're having lol

Ya still working away on it, hopefully soon! The manual V6 was a blast to drive N/A, hit the track twice and got 14.4@103mph I believe(traction issues)

heres some updates I haven't posted yet

So I spent some time finishing off my last charge pipe and came up with this contraption

which put my MAF down here

Not even 24hrs later and I chopped off half of that charge pipe and started from scratch though

lol but happier with the placement of things, I'll grab some pics later when it's not so dark in the garage

_HeC_ · 07-10-2016, 01:30 PM

This should be better, might still mess with a small section of the charge pipe by the TB bracket

Decided to get a new wastegate to get a much smaller design and v-bands, also went with 44mm VS the 38mm Emusa

Going to be sitting something like this, still need to cut that pipe down a bit

_HeC_ · 07-10-2016, 01:31 PM

Might as well update this I guess, it at least give me a nice "journal" of my build lol

Got my drive train out a little while ago

Inspected my "stage 3" ebay clutch and rather happy with it after 16,000+kms with no proper break in and beating the shit out of it

drilled my pan for oil drain, thought I could get away with a nut and loctite but not enough thread showing

So dropped it off at a local shop that I use for my TIG welding(Re-Speed) and some beauty cars out front

Last year I lost my steering rack tabs.... NOT this year or anytime soon lol 1/8" plate on both sides

Lifted fuse box 1" and relocated wires from the front out the back

last year I had some TERRIBLE traction issues the 2 times i hit the track... Got a closer look at my poly rear mount and damn?

New one is here so little fire with the old lol

GTP 36# inectors/connections and my PCM flashed for them thanks to Scott!

ohh and got myself a WOT-Box for some 2-step launch control and no lift shift

very impressive and well documented build here. I like what youve done.

_HeC_ · 10-16-2016, 09:15 PM

Thanks man, guess this needs some updating as the car is driving...

3" downpipe, wanted it to be 1 piece but wasn't happening

Girlfriend painting all the exhaust parts with some POR-20 heat paint

Some heat management

Quick clean to make sure no debris was inside

Notch for oil return

Screamer pipe
