He had to 'upgrade' to 600CC injectors, which is absurd since the stockers are ~400CC.. how tiny of an injector did Stillen include??? lol

My kit came with 600cc injectors.

Did you buy the kit new or upgrade it in any way? It didn't use to be 600cc.

Did it always? Quite a few people had really high idcs on their injectors. Hopefully the improved that part of the kit.

IDK about that.
I have a new kit on my car and it came with 600cc injectors.
BTW, I do not experience any of the problems that are constantly mentioned here.
The kit max out at around 460 RWHP, which incidentally it's not very far of what the stock motor can take safely.
The kit as it comes makes 409 RWHP, but the fuel tables shows a very rich condition, then when it's properly tuned goes to 440 RWHP, on a bone stock car (factory exhaust included), not bad at all for a sleeper.
Realistically our motors are safe up to 500 RWHP with a good longevity ahead.
If we like to push the envelope further, then a short block is in order, a TT set up, big intercooler,etc,etc, and 700/800 RWHP is attainable, but I don't think the tranny can take it.
Back in 1992 when I had my second 300ZXTT, I max out the package with stock internals and the car makes over 500 RWHP at 2 bar, it runs very reliable with no breakdowns,but the tranny did not like 473 RWTQ, so powershifting was a big nono.
However I'm always have a lot of fun with the Z cars.

Very nice HP. Is your car manual or auto. I have installed Stillen now headers and cats. Should I return stock headers? The cat's material inside tends to break apart. The question is whether to clean the interals of the stillen cats out and leave them as test pipes or to return stock cats.

thanks

What kind of dyno are those numbers from? For an unmodified kit, that's pretty high. What does a stock 370 put down on that dyno?

Dynojet424xLC2.
I will post it the actual page of the report from DSPORT
This is after SC install, no tune.

This is with tune, and cat back.

It may come with 600's now, but a year ago it DID NOT come with 600's.

I know this for a fact.
