Hustler, get on that MS setup so I don't have to be another test monkey and I can learn from your mistakes.

EDIT:
I think we just created the NB subforum, have to start small right. Keep it down to one thread and it will be HUGE...
atleast in the NB world

No, that's one thing I would like, but it would be too easy. Seriously, that would be one of the best reasons for me to get an aftermarket ecu.
I depend on other stuff, older stuff that I've used for years.
Reading afr, egt, fuel pressure, knock sensor, plugs, timing, listening for knock.

I don't have a problem getting an aftermaket ecu, but I still want to see what I can wring out of the oem unit. Unfortunately I enjoy the experimentation. Maybe there's something else I can use to datalog fuel and timing without replacing the ecu.

You know, there are/were a lot of turbo NA's making over 300 rwhp, But I don't remember any with a stock engine running nitrous at that power level.

Oh, I know you weren't... that's just my posting style, it's a little raw and unfiltered. Bare with it... you get used to it after a while... I'm an affable and friendly guy, I just type a little crotchety. The manifolds can be problematic. I had to modify mine substantially, I picked up the SSGhettochrome manifold. I built my own downpipe, so it had no fitment issues.

Mine is also in bits in my garage. At least I am rocking an intercooler for that turbo look!

Have any of you NB owners had issues with the fuel system like some of the recent year MSM guys?

I've got the turbo/mani/EMU (in the mail)/BPV/injectors. Still shopping for the NB. Test drove another today. There's a '99 with high mileage for cheap that I'm trying to check out.

cccpull,

I'm surprised you bent rods. I snapped mine on my '90 probably 6-7 years ago running a T25 at 16 psi and a 50 shot. Admittedly I had some detonation that sealed that motors fate. Swiss-cheesed the oilpan.

lol it looks as my GF and I might be broken up. LOL even though I told myself I wouldnt turbo the 99 i've got some money burning a hole in my bank account.

As to the question by CCCPull. The JR timming controll is not elegant or as accurate as a full out ecu. Yeah it works but it does so by fooling the ecu not by actually doing it on the board. Seems as if fewer NB's with full out ecus have blown rods than those useing piggy backs

You seem to imply it's just tuning, but I don't know if any of those guys were on boost and nitrous with stock rods.
You still haven't explained why the rods would go.
I know it's not elegant and I might not be wringing every last hp, but it does the job. At the moment hp isn't my problem, I'm runinng 16psi and until I don't get more traction I can't use more. 1st and 2nd are useless.
Also, where are all he NB's using piggy's vs full ecu with blown rods?
Just to compare, 'cause I don't remember that many. (besides mine):gay:
Thanks

All I am saying is that there are many theories on the rods

1) That they are not the same as the NA 1.8 rods
2) That most have been lost due to timming issues when using piggy's and higher boost

thats all i am saying.

Takes long time to start and if you pull a connector at the motor, even after changing the fuel filter, almost no residual fuel pressure when the engine is turned off.

Have not been able to run test on the pump because of need for snap on quick disconnects. Since it is under warranty, told him to have the dealer run a check on the pump.

You're right, I've heard some of those theories, too.
I can tell you I ran 12-13 psi with 50 hp shot, no problem, 75 shot, problem.
I know of a case with a tec2 or 3 (can't remember) that also broke a rod, not like mine that just bent a little.


So which turbo are you looking into?
