When you wind it up it sounds like a Porsche, not at all American or Japanese. Steve Ganz carries them now. I've had my set for a couple of weeks and really like them.

Pretty much trial and error with the exhaust note,should be pretty cool though,since the turbos will help to keep the boom/rumble out of the huge piping at the lower revs.
That ecu may come along here soon and become something pretty useable,as for the ignition,isn't there already separate systems made be MSD that would do what you want?

I had that *exact* same problem. I just pushed hard with my foot and it worked.
As for exhaust, I have a complete custom setup made. 3" all the way from the turbo, 2.5" from the split on. DynoMax super turbo mufflers. No cats, no silencers. Gave it a NICE throaty sound, no rice at all. Sounded more like a chevy 350 than anything else.SR

CWIZ that last post you made was very, very helpful. Thank you very much. If that is how it is supposed to be then I will simply force it to mate with the stock setup for now and then really think about the exhuast. Chevy 350 exhaust note may be too loud for me. Any droning and resonating in the cabin?

hermosa..youll be fine with a custom exahust and save alot of cash.....
do a 3in splitter in to 2 2 1/2 pipes...i would reccommend 2 resonators on the exahust sections to keep it a little quieter.....and then the 2 2 1/2 mufflers just like you showed pictures of...that will work perfect and be very nice sounding....NOTHING like a truck or civic..i promise...but you need to get rid of that stock stuff....thats is not good for turbo at all....Jeff
PS nice avatar steve.......looks like a proud new NSX owner

Just razzin ya Jeff... There is quite a bit more up top without the flow restrictions in the stock setup. I can't say HP wise, but at the track, the car made at least 3-4mph better through the trap by pulling the exhaust from midpipe back. I don't think the dyno guys would appreciate an open pipe in their shop.Clint did a custom setup using inexpensive Summit straight through mufflers. Instead of resonators in front of the mufflers, he just did four mufflers, two in-line in each branch. The Summit ones are offset and oval, with a 3" inlet, and outlet.
Funny thing, the midpipe I got fit PERFECTLY.....

Jeff...SC300Turbo
Hey Jeff...
I ran into Ice-T at a certain gentelman's club in San Francisco about 2 years back. (ahemm...Mitchell Brothers..aheme).
He was there w/one of his boys.
I was just sitting back for a bachelor party there and ran into him there. We saw how he and his buddy were trying to just get stuff from the girls for free.
A girl I know who works there...was telling us how he does that every so often. Almost like "pimp recruitment"
The SAD thing I saw was that one of the club's ushers was all on his nuts saying "hey..I got all your albums...and if you ever need anything...just let me know..I'll hook it up"
Ice...thought about it for a second..tossed his empty water bottle to the guy and said "Hey...throw this away for me"
Man..that was pretty embarassing for that usher.
BTW...nice car. =)

Titan spins theirs to 10k? The AEM and other true standalones is the only way around this hurdle. The turbo maps all say that I can get another 50-75rwhp by just raising the rev limit on my existing setup (combined with cams and headwork).

are there other cam options for the motor, besides a custom fab set?

Hmmmm........
The ge has a distributor. The gte runs coil packs (distributorless ignition). Therefore, tt cam upgrades will not work; or they will work only on the intake side. But for turbo purposes the exhaust needs to breath. So to run cams in a ge one needs either to convert to packs or go with custom grinds.

I am loving this thread. There is some good information being thrown around. Keep it up!
I think I will initially keep my exhaust and then get it redone when I get it dyno tuned again. The shop does not do exhaust so I have to do it later.
My only trouble right now is custom intercooler piping. If anyone has any connections to parts or someone who does the work real fast then I am all ears.

Turbo Exhaust article
Hermosa (and others), I found this discussion about exhaust on the LexusHP forum. I'm certainly no expert, but this guy sounds (to me at least), like he knows his stuff. It's a good read if you're considering a custom exhaust:Turbo Exhaust Discussion

LexusBoi,
You are correct, no one makes the set for the GE. You can send them in to Crower to be re-ground, though. I did it to mine, and I believe Ethan has them in his vehicle. Its not very expensive. The profile I got was 270/268, with pretty good lift near the specs of the HKS 272 cams. I think Ethan has the same thing. Only drawback is that you have to install lash caps over the valve stems. It also changes the requirement for your valve adjustment shims, and may cost a bit to have these shims special ordered from the dealer. I thought I remember Ethan doing custom shims to eliminate the lash caps, not sure though.
