what else can i do before upgrading the head and cam i have a detroit tuned by pass valve, dinan intake, alta 17% super charger pully,cat back, and a pnp unichip ecu?

 

I would talk to the shop that's going to be doing the head/cam work and ask for their opinion.

When you get to the level of mods where you're at, you really have to take a holistic view and think extra hard about how everything's going to work together. For instance, the shop probably isn't going to design the head for extremely-high RPM operation if you already have a 17% supercharger pulley, since the max engine RPM is going to be limited by how fast the supercharger can safely spin.

But just off the top of my head, if you've already got the intake and cat-back and are going to be increasing airflow even further with the new head and cam, it's probably time to look at an aftermarket exhaust header and high-flow catalytic converter. With everything else you've already done or are planning to increase air flow through the engine, the factory header/cat is probably going to be a weak link.

You'll also need more fuel to mix with all the extra air, so some larger fuel injectors are probably in your future as well.

 

I have to agree and go with injectors and header, although if you are going to upgrade injectors now you would want to go with 380's, but when you do the head you will probably have to upgrade to 440's. So it might not be worth it to upgrade injectors now. You might want to look at upgrading some suspension parts as well.

 

i wanna upgrade the head later much later. i alredi have some suspention parts i have h n r coilovers, alta 22 mm rear sway bar, and a m7 upper strut bar, in addition i have a alta short shifter, msd coil pack, and a tsw v2 engine dampener. so my dinan intake did not come with a upgraded silicone hose, would that make a difference? also my ecu isonly tuned for a s/c pully , my intake n and a msd coilpack(if that made any kinda difference with the tuning).

 

Buy a piggy bank, save up for a cam, header/head/exhaust, combo with tune. This will make you happy. I know Im sounding like the new Rustyboy but I have bought everything twice! Don't do what I did. Otherwise, go nuts on brakes and coilovers or something.

 

If your gonna do a head much later, go with a header, injectors, and just buy the cam, you can always swap it, and then get a tune from jan!

 

Silicone hose makes no difference. Looks cool though!

 

+1 on header and injectors
Also, a tune specifically for your car, but might save money getting cams now so you don't gotta pay for 2 tunes
