Yes I agree it's a good set up, should be all you need.

Does anyone know off hand what fabbing would need to be done to make a Z kit fit a G coupe?

Thanks

Awesome, thanks.

Im having a hell of a time with the drivers side IC pipe mating to the cast up-pipe, and I saw on the first page Sentry wrote so I was just curious

i am new to posting and to my350, so i am hoping y'all can help. No need to bash just provide useful knowledge or insight to help a fellow member.

i have a 03 track model 350 so non rev up with about 115k miles (most of them hwy miles due to commute about 30miles a day). Car is very well taken care of and never had 1 mechanical issue.
it has been driven with just CAI, hi flow cats, borla exhaust and there was plenum spacer installed a while back.I finally wanted to get into something quicker so decided to go FI rather than buy a new car as i love my z.

i bought a v3sci tuner kit, dw600, intank walboro fuel pump, 1 step colder ngk plugs, an oil cooler and catch can, long tube headers to get rid of cats also have full set of gauges including wideband a/f. I will be using uprev osiris to tune.

i bought the 2.87 pulley to upgrade right away as i want to be over 400whp but really no more than 500.

with the supporting mods i have, and the state of the car being a DD and my goals in mind, is there anything else i need to get/do to accomplish and have a well built and functional Z.

(fyi- vortech said i need to machine the pulley to get it fit the jackshaft, is this true? do i need a smaller belt to run the smaller pulley, and if so what size? the dyno shop in AZ said i should 100% replace the rods, pistons, and bearings since they have seen many z's (DE) fail right on the dyno going over 380whp... is this true, and if so can anyone suggest what to replace with?)

Thanks again for the help!

I have similar setup (here is my build https://my350z.com/forum/forced-indu...n-03-350z.html), with 3.12 pulley pushing 427 Whp and 370 torque. I think 2.87 will bring you close to 450 and 400 torque which is too much for the DE engine. If you want to do it right the first time - build your motor, especially with 115K miles on it. For the 500 whp you can go with Eagle or K1 rods and Wiseco pistons. Everything you need is here on this forum was posted many times, tons of different builds, so use search.

Thank you for the insight. I dont want to go that high and think that right now i may just swap out the pulley and run somehting like your set up and then when the motor goes due the rebuild then... i know its a matter of opinion (build now or later). So if i dont want to build the motor now, i can run the 3.12 pulley with what i have not replace the internals and get over 400 correct?

You can run any pulley with your stock internals but nobody can tell you when your engine will give up. You have to be ready it will give up sooner or later and no matter what pulley you are running. I know mine won't last long because i am pushing it, so I am building an engine right now.

completely true. i think i will keep the smaller pulley for future.. run the 3.12 and rebuild once the motor goes and then drop in the 2.87. Is there anything else you did or you can think of that would be good to add to the current setup i'll be running?

I would also recommend Fuel Return System from CJI. Get stage 0 it will help with tune other than that you are good to go.

This post (from a few pages back in this same thread) shows you what needs to be machined on the 2.87" pulley:

staisman and bigc, thanks for the input ill check them out. and if anyone else or if you guys want to add anything, the input is welcomed.

oh also i forgot, is upgrading the MAF to the uprev MAF a good idea with this setup im looking at?

Staisman

iTrader: (13)

Yes, factory MAF u will get maxed out at around 400 whp.

what are you using for Tuning?

OldManZ350

iTrader: (23)

Not True, depends on what you control it with.

With uprev you will need to upgrade.
