I'm gonna go with the cjm kit .... Once I break down and order it ..won't be much longer ......then I'll set up a custom tune .....

Well to start,I got a few miles on my stage 2 sc kit now,quality of the kit is a 10,the car drives and feels like stock while driving normal,the boost is addictive, all other upgrades I did with the kit like csf rad,thermostatic oil cooler kit are a huge change,car runs alot cooler,ecutek tunning is great,I can't say enough about seb at specialty,he is awesome to work with, gamma has been nothing but good to be with service and parts,iam still working towards the best tune with seb n ecutek,I have the smaller pulley on my sc(92)but so far feel feels great and has more then enough power,I also have the 85mm pulley but will hold off on it and keep enjoying driving my z,future upgrades include clutch\flywheel,stabilizer bars,tires etc the list will go on,also I'd like to do a built short block in future aswell,I did all the work so far on my car and it has been great,cars are built not bought,u can't really appreciate the full fun of a car if you didn't build it yourself,just my opinion,thanks guys on the forum for any help and thanks to the guys that run the forum for letting me post on here,I'll update as more parts show up:driving:

Glad to hear everything is running good ....keep in mind when you go to the 85mm pulley you will need to go with the upgraded fuel system ....mine should be here in a few days and can't wait to get it tuned up right

Ya gona run the 92mm for a bit,I always ran my car near redline when it was stock and like now the power comes on but eventually will go to the 85mm.

What brand of fuel system did u decide on?

I got the CJM kit .... Should be here any day now

Good call

Fuel kit has arrived ...hoping to install it next Saturday

Fuel kit installed ...running return line was awful but done and over with ...ill be testing it in the morning to make sure it will make the drive to z1 for tuning

Right on,cant wait for results,iam experiencing a little fuel psi lost real high in rpm even with the 92mm,car runs great tho,breaks loose tires first 3 gears which isent a good thing but sure is fun.

Any luck with the fuel return system? Have you had a chance to dyno?

I have it set to 52 lbs fuels pressure and afr is now a little on the rich side all the way through the the rpm and full boost ....I don't have the vacuum line connected while running it this way and it maintains 52 lbs with out pressure drop . Now with vacuum line connected with same settings pressure is dropped to 47 lbs at idle and as boost comes on afr go very rich and continue to get richer to max boost/rpm .....so at the moment I can't do any more adjustments without changing the injectors settings in the tune. .....hoping to get a appointment set week after the 4th of July for Dyno tuning

Are you using 91 octane or 94?

93 octane always

Ya all we have nearby is shell 91,we are supposed get petrol super 94 soon I hope

Got my dyno time set for July 5 ....hope everything works out ok

Are you driving it daily with the 85 on as we speak?if so how is it?

I'm still on 93 octane ...I don't think I'll go to the e85 due to it being a daily driver and lack of e85 pumps locations .....I'm just hoping to break the 500 whp mark with 93 octane after that I'll be done. Wish is wasn't so hot when I'm doing the tune might hurt my performance.

Sorry meant 85mm pulley not e85,iam gona stick with 92mm pulley for this summer,budgeting for the return fuel system,clutch etc,with the ecutek tune there's plenty of power for the street.

Oh yea ill keeping the 85mm pulley at 7200rpm I was at 12.3 lbs so I'll have the boost earlier in the rpm range ...I don't like going over 7k anyway and with the 92 mm pulley you will hit 8lbs at like 6.9 k rpm ..ill be at 8lbs around 5.2 k

Ya even when my car was stock I always drove it near redline most of the time so boost up top is all good,ill save some money and do a bunch of mods over this upcoming winter,iam thinking of getting into some engine internals to make up for our kits boost limits.

What tires are you running on rear?

What time off internal mods will help with whp with our kits ... Also I have the nismo so I still have the 265 front and 280 rear....when I replace them I'll do 280 front and 305 rear
The 85mm gives plenty of boost compared to a turbo for stock engines

I have a 15 Nismo and did the 285/30 front with 325/30 rear. It looks the part. The 325 made the 305s look insignificant if thats possible.

Hmmm any issues with rubbing or slinging dirt down the side of the car ?

Iam doing my research as we speak to find out what internals would work best with our setups,ive found some jwt exhaust cam shafts that should help with torque,seb from specialty said on our setups with the 85mm pulley we could get to 550-600 whp maybe with proper supporting mods like the fuel return etc,the torque number is the key,iam curious to see what you get on the dyno for wheel torque.

For tires I would think a 305 would be good enough I'd imagine,if you really want to hook up go too a different size rim that would allow for a taller sidewall.

I think 550whp would a generous guess ....I was thinking maybe 500-510 at best ..I do have the nismo exh which I think is pretty good ... Now maybe he was referring to 550 whp with ecutek and valve tuning .... I'm still using uprev ...I'm kinda concerned with dynoing in July with it being so hot and not getting best dyno numbers

The correction factor will take into account temperature. Std is something like 72. So it will figure that in along with humidity and elevation. Just tell them you want it corrected. 99.9% of tuners use this number anyway because they want to look like they tuned you for maximum power.

Tiller.. Do you know if he was meaning our setup with ecutec or just in general ... I haven't seen anyone with much over 500 with our setup

None and I'm on Ark GT-F springs.

I asked seb his opinion on the setup I have with ecutek,the 85mm pulley,fuel return kit and 93 or higher octane tuned right he said 550whp should be possible plus. 500whp would be more then enough with good traction,but I aim high lol

Well I'll see what I get with the uprev ...wish they had timing control but...ill have to do without for now .......hope Z1 knows what they are doing

Z1 sounds reputable from what I've heard,the ecutek does have alot of extras like the timing control etc,guess we will just see what numbers you get and work from there.

Yea not long now

Question for you, with the engine mount(s), primarily the passenger side one.
Did they supply a bolt which goes from the new engine mount to the chassis? I got the 4 new bolts which bolt to the engine block and the instructions are a bit vague in this area.

When are you going to Z1? I'll be there on the 24th and 25th. Tuning day is the 25th.

Only had to replace the passenger side mount with my kit and they do supply bolts for installation to block but you reuse lower bolt to chassis,also I made a small tool to tighten the block bolts if someone is at the step so I didn't have to remove exhaust manifold.

I have dyno time set up for July 5 9am

I only replace the passenger side motor mounts ...I read that doing both made for heavy vibration and was recommended to leave the driver side stock

I only have the 1.5 kit so only doing the passenger side.
We have mocked up a tool so we do not have to take off the exhaust manifold and tighten the bolts down. Good to know about re-using the bolt for the chassis, will see how I can go about getting it off the old engine mount.

:/.... I took the header off when I did mine
