The blower is on and everything is good to go, however I would like to make some more power. I have done numerous searches and didnt come up with much.

Best header/exhaust?
should I look at a S-AFC or Power FC?
Flywheel/Clutch?

All opinions welcome.

thanks

 

just dont mod it in anyway to make it run lean....

 

where to buy such products?
Thanks

 

clutch and tires are probably your best mod right now. Headers, exhaust etc, aren't going to give you any HP gains on an FI engine.

 

if you want more power, get an ATI Procharger IN ADDITION to the stillen s/c

Yeah, you could always get a nitrous shot after the SC, that would help cool things down and prevent the detonation problem that's been seen with the Stillen SC. Plus more power.

 

And of course JesseEnglish was on crack like Calvin when he said this.

 

I know right ! How can headers and a less restricitve exhaust not benefit a supercharged Z ? Your car still needs to breathe....

 

Headers, intake, and exhaust are very important on FI. The more freely things flow, the more power that thing will produce.

While the Z's intake and exhaust aren't the most restrictive stock units, I think it's crazy to have an SC and not have the exhaust mods done before hand. Your motor is a pump, the SC is helping it pump more, but you forgot to increase the size of the pipes.

 

My bad, I meant to say it won't give much gains. Not really worth it IMO, because the stock system is so well designed. The money would be much better spent on transferring the power to the ground.

 

The hp increase by adding both an intake and exhaust will be more noticable on a boosted engine.

I would first wait for stillen to release the air to water intercooler for there SC. That will be the best gain power per dollar. Then find out what the A/F ratio is on the car. If its safe i would run headers, exhaust, and intake. you will benifit from it. just my .02

 

I hate to jump on the bandwagon here, but with a supercharged/turbo engine, exhaust work is a MUST. Simply put, you're cramming all of that extra air in there and you have to get it out as efficiently as possible.

One time (geez, ~10 years ago now) I put a vortech supercharger into a Saleen Mustang (stock 302) and ran it that way for a while. It was much quicker, but not how I felt it should be. After adding headers and a high-flow exhaust system it really came alive.

I ended up adding different injectors, big fuel pump, fuel pressure regulator, and ECU mods to deal with it all. Then it was sweeeet.

Superchargers are great, but they're "part of this complete breakfast" if you catch my drift.

 

A 2.5" system made for FI.

 

I appreciate the help from some of you.

Where is the best place to get the exhasut pictured?
I was thinking of getting the nismo full exhaust sytem but I am having a bit of trouble finding the right vendor.

 

This would of been better put: mod it away, but make sure you get tuned

Yep. A small shot (maybe 50-75) would cool the cc's. However, I would rather run an intercooler than use this primitive method

 

Look into some colder set of spark plugs, maybe an exhaust system, or even a clutch. Or you can get some nice gauges or even a wide band 02 setup so you can see what your car is doing. This is a good start.

You may want to hold out on other modifications due to the fact that, there is no good stand alone systems or chips available yet. Pretty much any modification you make to the engine will increase the airflow and there is a possibility that your engine might run lean. Headers, high flow cats, cams, and intake manifolds might just off set your tuning. Once a company comes out with a good chip or stand alone, you will be more open to other accessories you can add to your engine. Once they come out with this, your possibilities are endless.
