jeez that should have been somewhere around 280-310 rwhp, no wonder they let loose. But how long did they last that way?
Took a good amount of 50hp shots, but didn't take that many 75hp shots.

Even the built engine threw a valve with the same blower setup and a 125hp shot. Didn't like it.

Yeah, that's why the N20 is installed, but disconnected.

I'm just crossing my fingers that one more NB shows up on the poll.

No, the HKS-SAFR, JR-BTC, intercooled and water/alky injection. The N20 was/is a wet kit, so an aftermarket ecu wouldn't have saved me.
At least in the case of the rods, I don't think it was just the power, but the way it hits. The N20 hits pretty hard.

I bet that rod might have lasted, or lasted longer with a proper ECU.

It looks like I'll be rockin' some SCAT rods, with this turbo. This is on my 99, which has seen 250 RWHP on the stock rods, and I've seen 280-300 RWHP on stock '99 rods.

Looks like its a fairly big turbo, should flow about 45 Lbs/min at most. (roughly 400 WHP)

What brand of turbo is that? Looks like the "Turbocharger" made in bangkok kind i see on ebay. Huge and clean though, should be badass, long as it doesn't explode at 4 psi.

I don't see the correlation. I don't see what an aftermaket ecu could do to save the rods if my fueling and timing were fine to begin with.

If you care to explain, I'm willing to listen.


I see MarkP joined in with examples of what he's seen, which I don't doubt at all, except my setup plus the N20 was more hp than that. He might provide some explanation.
Like I said, the N20 hits pretty hard.

Why not, this will be the first thread. We'll put a DIY in there on how to buff out your clear headlight lenses to take them from fog to clear as new.

lol, I just used some rubbing compound, worked perfect. Only reason i said that was because the NA obvioiusly don't have any plastic lenses to buff..

Man that makes me want some of those awesome MSM headlights, they look too great.

It is a chinese import T3/T4, I think the statements that these turbo's blow up at 4 PSI is a bunch of bullshit, especially after examining this particular turbo. (e.g. The housing is not epoxied together, the wheels look perfect, clearances and play are dead on.)

For $200 delivered to my door, I am going to experiment. I am willing to bet that it does not fall apart and more to the point that it will make adequate power. The only concern I have is the center section and it is copied so exactly that it retains the subtle casting marks that are in the Garrett castings.

While certainly not of the highest quality, it is of adequate quality, although I can note where several shortcuts have taken place. None of which would affect the ability of this thing to hold together. To quote Corky Bell, "Building turbochargers ain't exactly rocket science, and these look like surprisingly good copies of the garrett." Still the jury will be out until I start running some boost through the sucker and seeing if it really does hold together.

I wasn't ragging on you about the turbo, though it looked similar to what I had seen. There was some thread that showed the poor fitment and whatnot of coolant flanges and the downpipe flange as well. I'm actually looking forward to seeing what you find out about these chinese copies because they're so cheap the might as well be expendable. Goodluck

The rest of us can't afford one of those fancy NBs. We have to turbo our near-antique NAs. :gay:

damn, didn't expect this thread to get more than a few hits since it's about the rare turbo nb.

back to rods... I dont know if it's so much that they're weaker or just the higher compression hurts. I'm babying my car until I have a real solution or spare bottom end. Most likely I'll save up (ie wait for my stock options to mature a little more) and build it up a bit. I'm torn since it's a street car if I want to do low compression or just toy with something higher. Everyone does turbo with 9:1ish. Would a street car benefit from boosted high compression? Hmm.

cccp: how do you know your timing and fuel were dead on? can you datalog your setup?

my turbo system resides in the floor of my garage; waiting on the 1.8, MS, exhuast, and a running daily driver.
