NISMO JGTC VQ33DETT engine SWAP. hahaha

Since the ECU re-learns around certain mods I'm sure it can't be anything that effects metered or incoming air. Also, the issue of "one mod" is not relevant since you want a system of mods that work well together and it's unlikely you will only perform one mod to the car. Each car is different and the same piece may not act the same on each car...so what you want is to choose parts wisely (quality, budget, goals) and have them tuned on your specific car for thebest performance (ECU flash).

Hey phile, its all good. At least we are both on the same track with trying to find some good answers about mods.

My vote is lighter tires and rims. Woooowooowowowow

Its definitely got to be my new "Z" Nissan badge on the front of my hood!

Cams or ecu!

phile - you got the right idea... I would be wary of a final drive kit for the fact that our gas mileage would suffer even worse (I average around 16-17 mpg in my G35C) - however, it has been reported that with the stall converter, a sedan that used to go 80 @ 3000 rpm's now goes 84...

I've really just started the mod process on my car (let the newness factor wear off first), so far I've done an intake kit, and have a set of test pipes and the UR pulley on the way - next on the list is going to be the stall converter, kinetix plenum (if the kinks are actually worked out this time with the cracking issue), and maybe an ECU reflash - depends on what it feels like after everything's done...

I'm definitely staying away from the high-priced exhausts, but will be looking to upgrade the y-pipe in the future as well.... gotta do all this before I get married in November because the frivolous spending will be held in check after that (she's definitely the saver).... so I better make sure I get that set of 19" Axis Hiros before then

tires are the single biggest improvement you can make to these cars from stock.

If you don't have good rubber, wait til you do than add some mods

give us a few days, I think we can test this theory once and for all.

quite a few of us now have active data logging of the cars sensors, and that includes air flow and timing.

if the ECU is somehow adjusting for additional air flow it will show up in the O2, MAF, and timing numbers.

phile

Yeah, I know what you're saying. But I just thought it was an interesting point of discussion. Also, some people really only may be able to afford one mod. Other people might just want one solid mod and leave it at that. I think it's a very relevant issue



No doubt. I like to learn It's all just a matter of gaining an attention span for me



Good point about the gas mileage, I never though of that. Still, I wonder how a final drive would affect our performance? Oh, and I'm not sure what a stall converter is :P

spend all the money you can before you get married!I havn't seen the Axis Hiros yet, I'll have to give them a look.

Why would you want a shorter final drive. You have enough torque and short eough gears to get through the powerband.

phile

I didn't say I wanted one. Just a discussion :P

the shorter final drive I think is going to be one of the best mods going for guys sticking NA - it will easily have the signle biggest effect on acceleration than any other mod.

Biggest bang for the buck I did so far as the cats/Y pipe and my ecu (mine was flashed after about 11 hours of dyno tuning, so was not an off the shelf map)

I might change my mind when the new clutch goes in

Z1, you're right... the final drive kit will be one of the best mods available to increase acceleration - BUT, the trade off of worse gas mileage will have to be taken into consideration when doing this (whereas just about all the other mods mentioned actually increase gas mileage to some extent) - it's a decision that someone who uses their vehicle as their daily driver will have to put more thought into than someone who uses their car sparingly and/or as a weekend racer... but will definitely be the key to lowering 1/4 mi and 0-60 times significantly...

I'm not sure if it's out yet but I believe there is a 4.3L stroker kit. That's probably number 1. Number 2 is definitely testpipes/hf cats.

phile

Yeah the AEBS 4.3L stroker kit is out. They are sold out already I think. Although it DEFINITELY is the single best NA mod, it also comes at a heft price tag of $7800! I would love to do it, but I just couldn't dump all that cash, when I could just as easily go get a nice bike idk.. I wish I had more money :P

lafdclass002

What kind of HP does this stroker kit produce? Does it greatly affect engine life?

phile

Being that it's an NA mod, it's the safest route you could go. It would actually increase core engine life provided you left it alone after that. Stronger rods&pistons, stroked crank, and sleeve kit. It's able to handle up to like 28psi or more if you go the FI route (by buying the lower compression pistons, and installing an FI kit )

Better driver will lower your times in the 1/4 any day of the week.

phile

That goes without saying
