Thanks.
It gets loud, but only under partial to full boost. I sometimes wonder if I just got a cops attention when I romp on it...

with that many miles and a dream of F/I you should have went with a safer more reliable route. A supercharger would have been a better pick but i would personally have stayed N/A and started out by building the heads or buying some heads already built then while you have the heads off just build the whole motor and buy a stroke kit. Would have cost more than a bolt on turbo but would have saved you the headache now. and possibly the money you'll spend now.

I disagree. You can run a properly tuned FI setup on a stock engine with the proper tune. Many here are doing it. I haven't had any problems. I'm saving up for a build later on down the line when I feel I need more power, but I'm extremely happy with it now. It would be nice to build first, but honestly I didn't have that kind of time/money .
I wanted boost!!!

my buddy says to sell the turbo kit and worry about getting a motor. he said to safely run the TN kit on my stock engine, i have to turn boost down to 4 or 5 psi....i see plenty of people on here with stock motor running 8psi...

thoughts?

Thoughts? Your buddy is wrong. Over 70k miles and 2 years and still running strong on 8 PSI..

Just wondering if your Grandma helped you with the installation of the Turbonetics kit?

A couple of things we see wrong here.
1)Turbonetics kit with aftermarket exhaust
2)Aftermarket boost controller
3)Motor with 100,000+ miles
4)Unkown A/F and timing at WOT

All a recipie for disaster in my opinion.
Good luck with the build, sound like you went lean and snaped a rod.

Whats wrong with a Turbonetics kit with an aftermarket exhaust. I guess me and everyone else who runs like that with no issues is at risk too? Its too bad your public apology doesn't extend to shamelessly calling out a manufacturer for a user mistake...

I think he meant not tuning for a different exhuast then what the reflash Turbonetics gives expects to have (stock exhuast).

does that make it less like an attack?

I'm still not seeing an issue with running with an exhaust. I and at least 30 other people on this board have done so no problem...

You shouldn't need to tune for a change of exhaust.

I've already accepted the fact that MRC hates anything Turbonetics and anything he says will be biased. Therefore, I will not argue.

Well, I will say that the last TN kit we saw with a custom 3" exhaust, and he did have a plenum also,I should have mentioned that..Ran at almost a 13.0 A/F under boost(9-10psi) on our dyno.The kid was advised to retune for the mods or put the stock stuff back on.
He did not listen, and 2 weeks later a flatbed dropped his car off in the middle of the night with a bent rod.
I was not bashing TN, your assuming I was. What I am saying is that the kit was designed for a stock car. when you alter the airflow in and out of the car, you obviously will alter the state of tune.This is basic tuning 101.
The OP case may have been install related also, we simply do not know.
Please calm down.

Oh really.I did not know that. I was under the assumption that the TN kit was designed to run 7psi on a stock car. All of my training and experiences tell me that when you alter the amount of air a vehicle is allowed to flow,especially a turbo charged one,you will in fact alter the tune...

I have opinions on certain products, yes. However I was in no way attempting to bash any TN product.I was simply looking at the facts in this particular case and combining them with past personal experiences, to make an educated guess in what actually happened. There is always 3 sides to a story, the "A" side, the "B" side and what actually happened. The kid did say he had an aftermarket boost controller on the car, which to my knowledge the TN kit utilizes a stock WG spring as boost control at 7-8 psi, although we have seen some nasty boost creep from time to time, even with the overboost correction kit.
