shooting for 285whp-300whp n/a
#41
Cuz a buddy of mine put 278 with bolt ons and a ecu...u most not come on here a lot...265 can be done with basic bolt ons...itb's aren't needed it
#43
That is a gorgeous graph up there. 265+ has been done on a 3.0, a pre-programmed ECU isn't going to break records, having control and being able to account for variables during the tune will. Just saying... ITB's can push into the 300's, a wetdream . . . but a proven one.

Heads Decked
Fully Blueprint and Balance
Polished and Balanced Crank Independently
Balance as Rotating Assembly to 10k RPMS
Minimal at best, but it was performed for balance and reserved for a reason. You are correct, the heads flow very well from factory, but with the added average 50cfm that can increase the flow/gains a great deal in itself.

Z33 cam timing is most optimal for Z33 cams (which on the DE-Z are the same as on the 5.5 Maxima) and SSIM (since the intake manifold is similar to the Z33IM)
However when you switch to those BC 264s that cam timing is no longer optimal. I've read on my350Z about how one member played with cam timing on a DE-Z and Tomei 264s and his AFR went from 12.x to 14.x at WOT. That's a huge increase in airflow. It shifts powerband more than it adds power, (which is why anyone using Stephen Max adapters on a 3.5 swap/cammed DEK pays attention to the timing), but the fact that it improves breathing shows it will help peak numbers.
What's the setup on your G35, by the way?

don't want to go crazy with it like the maxima so leaning towards the exhaust

looks like a pretty solid setup to me. sure there are other things you could do, but the $$$ starts going through the roof when you get much more involved than what you're already planning.
i wish I had 2 maximas to mod. half the time I think about what I could do with my car if I actually went beyond the super basic 3.5 NA setup I have right now, but then other other half of the time I think to myself, why bother, just turbo it and make 450whp. I need 2 cars to play with.

Everything should be done next

Ok, a serious post. I think with your setup you should have no problem making atleast 280. Its so hard to keep adding power once it get up in this range though. This motor should help big time since you have bought bad motors in the past. From what you have listed Im sure you will make the number, but if you had ,Cattman headers and a cut out....... OH BOY!!!

You're against the EU, but do you have some other way to advance the ignition timing?
There is a lot of power to be gained just from advancing the ignition timing, more than you'll gain from simple AFR corrections.
You could always get some bigger injectors then pull fuel with the SAFC to advance the timing, you just wont have as much control, but it does indeed work. There is no way to raise the fuel pressure on the returnless system of the 5.5 gen, besides running another fuel pump in series. (Or maybe the walbro 255 will bump it up, but not much)

So imma just work with what I already have. For the moment

I'm against things that I haven't seen work for sure. I aint gonna take that risk and hack up my harness or have somebody else do it and mess my ish up. I had a utec and was waitiing for the PnP harness but that was a fail.
So imma just work with what I already have. For the moment

utec will have to wait a couple weeks. if you crack three hundred i know whats next :?

Just read over your thread and mod list. IMO you're going to want timing control. Rod bolts and rev limiter control would be really nice too.
The UTEC can be a PITA at times, but you can't say I haven't gotten good results with it. That 13.0 I pulled last year was on a 1.8 '60 with a 8.4@83 1/8th, and just pulled a 8.2@85 a few months ago (waiting for 1/4 times to go with it). That's with just simple boltons in my sig and self-done UTEC tuning.
