Check out this combination! please give me your feedback

SO here it goes i have a 2003 g35 coupe M/T which has a new engine short block replaced by infiniti, I purchased the cylinder heads and got them ported and polished, new valve seals and a multi angle job, I also added the cylinder head phenolic gaskets and the one that connects the plenum to the 6 hole inlet manifold, Also the throttle body phenolic gasket and pulstar plugs.

So far the car feels great and runs very strong, It had oil consumption issues and because It had 55K miles they agreee to replace the engine block. I purchased a cobb accessport unit and I am planing on doing some upgrades, what do you guys think ? my first one will be this parts:

JWT pop charger with Z tube
KINETIX v+ plenum with high flow cats
HR Y pipe
Car tune with the Cobb
Ported Cyl Heads

How much will be the gains? has anybody else has this combination ?

I use my car mostly during the weekend to the malls and for entertainment, I have a lancer ralliart as my daily driver, I just want to squeeze some more power from the g35 and a more aggressive sound from it.

Get rid of the Pulstar plugs for starters. They're junk and can do some major damage to your engine. I would suggest these as replacements; http://ngksparkplugs.ecrater.com/pro...hp?pid=2031849

Great plugs at a great price.

+1 on the plugs


ported/polished head work is expensive...not many have done it.

good exhaust with the HFC and a good intake will be good.

Cobb tuning could be a good option with the new tunability they came out with.

You're not really gonna gain much from the y-pipe.

I have a jwt filter/heatshield if you're looking.

Headers fit if you use the HR HFC's with them. This has been verified.

I'm not sure how much gain you are going to get with the the ported heads but with the stock cams.
