Do newer model Z's make more power?

verellic

Hey, sorry if this has already been talked about. I can't seem to find anything solid on it but have seen a few people mention it, including Z1.

As the title says, do newer model Z's tend to make more power on the dyno after bolt ons and a tune? I was watching a video from Z1 where they mentioned the newer models make more power typically, and wanted some more info on that.

If they do, I can't imagine it being more than a few HP, ie, not enough to matter. But I've been wrong before.

I believe the only difference is the newer models have direct injection. Although the manufacturer claims it's still 332hp and 350hp for the NISMO, some have stated, including Z1, they typically dyno slightly higher. I personally have seen no evidence of this. I have a 2009 and my dyno numbers have been very surprising. So if you own an earlier model and you're concerned with this, don't waste your time being discouraged.

Just my $0.02

I own a 2018 model, and I'm getting it tuned at Z1 tomorrow. I was just curious if there was actually any evidence of that after seeing them mention it in the video. Lets hope I put down some really good numbers with my setup.

Nope. There is no direct injection in newer models. The VQ37 engines are essentially the same as they were when introduced in 2009.

I would’ve been extremely surprised if this were actually true. It requires a significant redesign to incorporate direct injection into an engine, basically a new engine.

Well then I stand corrected. So with that being said, I have zero idea what could possibly account for an increase in WHP?

2015+ Headers are a different design. Could be a contributing factor.

2015+ exhaust manifold vs older

Interesting. Thanks for the info.

There are actually a couple of different things going on with the 2015+ model years. But the fact is any power difference between the models is essentially negligible. The weather variable can impact your dyno results far more than these minor design changes that have occurred over the years.

I would like more detail on this. The pics in the references thread weren't the best since one came from a Nismo and the other didn't seem to.

There is no difference between headers on a Nismo and a base model that are the same model years.

A couple of tuners have notice a small increase in HP on 2015+ Z with full bolt-ons over older Z's with the same bolt-ons. The one post I read said that there is a difference in the 2015+ ECU's. If I remember right. They have more RAM. There is basically 3 different ECU's for the years. '09, '10 to '14, '15+. Each up-grade has more stuff in it.

The only difference between a Nismo exhaust and the base models. Is the cbe and the pipes from the manifolds back. The manifolds are the same as the heads. The one year, they changed the exhaust stud location for the manifolds.

They actually have less ram on the newer models. Can't remember when it started. I think it was 2017 and up.

Rusty

There is more programming in them from what I read.
