My 2000 NSX with SOS built motor and OBD II twin turbo set up.

hopefully I get to see this beast sometime this year(2012)
Dudes and dudettes,
Update time. about 20k miles on my SOS twin turbo with my SOS built Peiserg 12-Zeta engine components (or as SOS likes to call it... Stage II build on their website)
I've got 90k on my clock now, which puts the SOS build/turbo at about 18k miles.. 9 psi/16 psi, 500 rwhp, 600 rwhp
Car ALWAYS starts, period. 30F, 115F, doesn't matter. No electrical issues, no hardware issues other than a blow off valve baffle breaking a year ago. Car ran great but wouldn't boost. SOS fixed it for PARTS only, and ate 4 hours of labor as a courtesy!!
Car still builds boost fast and early, and still holds till redline. Main issue is traction.

Good to hear the car is good. Good to hear that you are good also. I still have not seen the car and would love to hook up and see the beast....either one of them. PM me if you are interested or lets setup a run for the NSXr's here in Phoenix.
What mods have you done to the engine block?
the thread. read it.
Is the tranny internals stock?
I saw a SOS twin turbo setup on the lift at Niguel Motors this wknd. I inspected it thoroughly. It's a well designed kit. I love the lack of a scavenge pump. I was also *shocked* a new custom fabbed front engine crossmember was needed! That piece kind of blew me away and partially illustrated why this kit is expensive.
I will say... there's so little room for plumbing that I worry about lines chaffing, silicon hoses rubbing, or other components succumbing to the heat in the long run. Great to have the peiserg express his success with the kit. Please continue to update us!

I prefer to put the intercooler on top of the engine, where airflow is best. Lotus did that with the Exige. Mount it just low enough to not block the entire view from the rear view mirror, and then use a small air scoop to bring in more cool air when going at speed.
i've not had any hoses fail in the 18k miles. what i didn't mention was there are MANY track miles on that 18k.. maybe 3000? maybe 5000? I've beaten the hell out of that turbo system and not a single issue other than the aforementioned blow off valve (that took about 2 yrs to fail iirc)
Since traction seems to be an issue, do you track it at 9psi (500hp) or 16psi (600hp)?
Yes, but not with that boxer engine from the Subie. There was a European tuner that made a kit like what I described, with a huge intercooler.
The technical point here is that you want the air passage from compressor through intercooler to intake valve to be as short as possible, for improved throttle response and decreased turbo lag, as well as for a slight increase in air pressure and velocity going into the intake valves at WOT since the air passage is short and free of too many bends in the piping.

Pieserg, have you had to clean or change the turbo air filters?

The air to water intercooler does exactly what you are looking for without any obstruction to your view. Would love to see how this huge intercooler with scoop looked for a street car.

Yeah I had a chance to see and ride in 3.5L SOS TT car. Looked great but that bottom filter looked to be a pain! Glad to hear your setup is running good.
I prefer an air to water intercooler as well.
Like this one from Laminova:
It was used in this car:
I used to joke that they can empty a bath tub full of ice water through those intercoolers to further decrease intake air temperature.

Update..
missed a shift, hit some unfortunate RPM... oil light comes on immediately... zero oil pressure, engine stops, car dead on road..
stomach drops, chest pain ensues....
off to SOS, anticipating huge bill, and new motor...
A day later the call... "hey. blew your oil pump, everything else is in good shape."
WHEW. Testament to the built like a brick shithouse motor SOS put together for me!!

eeps!
(blew up oil pump or oil gear?)

Doesn't SOS machine their own oil pump gear?
