lol, nothing wrong with FI but I have a 750rwhp supra so no need for two cars that are a pain in the *** to deal with. I want a car that runs drives perfectly every day. the Z with 300-350rwhp would be one fun daily with out the head ache of FI

If you can get ~300rwhp on the G35c, I'd be very interested in this kit. Sounds like a good amount for a daily driver.

Nismo 46cc heads are $2000 but i wanna know if it is a big difference or not, it doesnt seem like anyone has done that just yet

Nismo is out till after the 3rd so once they get back we will have some more info on what is required to install them and the increase in flow hopefully.

We are going to Clay a head and piston to see how much valve clearence we have for over sized valves. if we have room on the stock pistons. if not we will have to use stock valves.

I'll save you the trouble...no need for an oversized valve on an NA setup...been there, done that, and won't give you any more headroom

porting and cams are where this motor will shine

Nice one Greg!!! Interested in seeing how this turns out.

I agree, there are already so many FI Zs out there already. It will be really interesting to see how far we can push our VQ Engines going the N/A route. Good luck!!!

I agree, find the best race machinist you can and port those heads the best he can. This should cost from 2000 to 2800. He will most likely have a flow bench and can reccomend the lift/duration cams to suit those custom heads. Otherwise, just use the most aggressive cams there are on the market. I think the Tomei 268 are around $1350 a set. Oh yea, dont forget the springs and retainers to go with the aggressive cams. Over sized valves should help and dont cost all that much. Im not sure but I think the oversized Ferrea aftermarket valves are lighter then the stock ones. More power through less rotating mass. Also consider thermal coating the combustion chamber on the heads/valves and the piston tops as this will help keep thermal effiecency higher. Id guess it might net another 5-10 hp. Along with these mods, a good intake, plenum, lighter crank pulley, headers, and exhaust will net the most power at the crank. Add a lighter flywheel should also net more power to the wheels. Last and foremost, get the car tuned to perfection. 300+ rwhp is certainly reachable with these mods.

"We are having some cams ground for us right now (a little more agressive than the JWT and nismo)"

Just curious why you are going with a pretty mild cam when trying to reach so much power NA. You say a little more agressive then Nismo in one of your post.

I'm sure you know much more then I do, and you know what is best, but this is just something I was thinking about.

Why not the Tomei 268 or something custom that is even more agressive then that?

I realize you may not want to loose to much low end and might be looking for better mid range power, but I just thought something more agressive would be needed for the power you want.

jsn350z this is being built as a street car package on a budget to reach 300+rwhp.

If we were going for an all out NA killer I would run some thing with more duration than the Tomei cams. 12+ compresion pistons and a Motec and individual T-bodies. All would be nice but totally priced out of the market.

The Nismo and JWT cams are not that bad of a set up for the street NA motors. We are having 1 set ground with a little more duration to see what we come up with and will compare them to the JWT cams which we have here.

In the end I want to have 2 sets of Cams avalible one for forced induction and one for NA.

thanks Z1

Sorry to not reccommend sumn that adds power, but the ZMI Titanium Brakes should offer something. They shave about 30 pounds each on the front two wheels and then the rotor replacement in the back saves another 15-20 pounds each. That's a pretty big save in rotational mass, not to mention a drop of about 80-100 pounds. That'll help your 1/4 and track times a little more than an intake.

I talked with Greg pretty extensively about this yesterday, and we are definitely on the same page - he wants to put a package together that he knows will get you a good number on the dyno, but will also be friendly on the street - I've done about every N/A mod except for Cams, so I'm waiting on these from Greg (by what he told me, these will be the most affordable ones on the market) and then I'm going to get the heads ported/polished and then get TS to do a custom tune for me... should put me around 290 when I'm done (I was a little over 260 after the headers, but I now have a different exhaust setup)... I can't wait to see what Greg comes to market with (ie he already has my CC# on file )

Greg is on the right track. They are doing ported heads (I presume) hence the cam needs not be the most aggessive thing out there (the Tomei 268's are not even all that wild). The cam needs to only have the right lift and duration to match their port work and their header.

Maybe we can have a nice NA shootout when its done Greg - there are very few of us building NA setups, and it would be great to share the knowledge base among knowledgeable people

what about sharing with UNknowledgeable people?

NA shoot out I'm game! strip, road track (VIR), and dyno. what ya think?

anyone interested in a composit intake? I am doing a little investigation in to having a design made for NA and for Forced induction just need to find some one to make them. I wounder if GM would be interested? lol

I have seen the Ti brakes before and inquired about there effectiveness in a road track/ street car set up. After talking with several people about these. I would only put those on the car if it was a drag car with a shoot on the back. strang has carbon brakes that are light but $5k for the front only to save 50 pounds is not really in the budget.
