So after 14 months, the car finally started for the first time. The car originally had a stock 02 LS1, Porsche transaxle. Did 333hp to the wheels.

Now the car has an LSX376, twin 6266 turbos, Precision 46mm wastegates and a pair of 64mm blow off valves, Lingenfelter intercooled intake, all custom piping done by me, fabricated and tacked, then final welding done by a local guy. All of this mated to a Lamborghini transaxle.

That's gonna be fun.

 

Nice I have always loved the Factory Five GTM cars.

 

that car is gnarly!!!!

 

Damn that looks so good

 

The car looks great. What does it weigh now? And what did that lambo trans axle run you?

 

It should come in around 2600 lbs now.

The transaxle cost about 18k to get everything, including axles, shifter, custom billet clutch, etc.

 

Outstanding work. Love the symmetry. Wish I could find symmetrical turbos that are reasonable.

 

Thanks, the symmetry was really a sticking point for me. I've had several versions of this along the way, but eventually was able to get as much of a symmetrical look as possible.

And yes, I'd love to get a pair of symmetrical turbos, but since Nelson Racing is so terrible at their customer service, I won't be giving them any money any day soon.

 

Wow man that looks great!!!!!
I bet its gonna be insanely fast.
Nice work for sure.

 

beautiful machine, drive her forever

 

Absolutely insane.
I see lots of tire smoke in your future.
Be safe!

how did you like building the gtm? i have been looking at both the rcr slc and the FF gtm.
i hear the gtm needs a ton of work to get the body to fit right.

 

Car sounds great.... enjoy it.

 

Wow that will be an amazing ride for sure!

 

Where and how big are the heat exchnager(s)? How much power do you think it will put down?

As said before car looks great! Love how simetrical the turbo setup is. Also it's really simple with the LPE intake.

 

I have not settled on the heat exchanger setup yet. I have the lines coming out of the intake, but trying to decide on a heat exchanger or going to something like a "Killer Chiller" setup.

I am shooting for 1000whp on the dyno at least once, then I'll dial it down to 600'ish for normal driving. It'll only see the higher power when I'm taking it to racing events.

 

I bought the car already built and running. I also heard about the horror stories of getting the body done correctly, doors to work correctly, etc. I also found a deal that I could not have built a GTM for what I bought the complete one for. I literally rebuilt the entire drivetrain, made a new subframe, rewired the entire back half of the car, etc. Having done that, I do think I would have gone with the SLC if I were to build it completely.

 

Someone has too much money i.e. 18K on a transaxle setup.

YES. I am jealous. LOL. WHo built the intercooled intake?

 

You will need a HE even if you aren't running loads of power. looking at the car you have a lot of space to mount them if you get creative.

There is obvious the front area but also the side pods. Then if you wanted to get creative you could do some lambo style rear mounted rads that take air from the rear wheel wells / scoops above the wheels.

With it being mid engine you are going to want the intake to run as cool as poss as its going to get hot in that engine compartment. Also might be wroth looking at getting the air out of the engine bay when at speed. The Ultima GTR and Noble M12 guys have done a lot of research into this (several Nobles have been in the wind tunnel). Let me know if you need any links.
