my current mods are the gm stage 2 kit, 3" hi flow cat, 2 1/2" pipe w/ hks muffler, jbp control arm bushings, injen intake, ngk irdium plugs, & 2.8" is on order....

my question is, what mod should i do next??? i would like to have several different opinions...i would greatly appreciate it...

i am thinking about buying the forged pistons from intense racing, if i do what ratio should i go with??? thanks

Rusty

i'd say do springs/shocks next. perhaps bigger injectors to go with the 2.8" pulley

moose

what springs and what shocks, if i do ever decide to lower it, i want it to ride as smooth as it does now....i lowered my zx2 and it rides rough.....

what about a clutch/flywheel combo? more hp and a better transfer of power to the wheels!

AGREED!^^^^^^

Rusty

anyone know what cams are available for our cars and any info about them? i havn't seen much out there...let alone someone who's installed aftermarket cams. however i think they would be a great piece to a performance upgrade.

Matty

JBP has a set.
Stage 2 cams have a dyno increase of 7 HP and 6 TQ.

That small of an increase on a 4-banger tells you that our cars have pretty good cams from the factory. If you're paying someone to install them, it'll be quite an expensive mod as well. And looking at the dyno scan of the install, it definately doesn't look like it would give you any sort of significant edge in quickness, since you lose a significant amount of power at the lower end of the power band. You'd pull *slightly* harder top end but bog a bit more out of the hole.

I agree with CrazyRican, do something to help transfer the power. You must have one helluva good stock clutch for it to be holding up to what you've thrown at it (mine's slipping already at 560 miles unless I totally granny shift).

Matty

Ya it isn't much for an increase but keep in mind that is without an HPTune, that would likely bump the numbers up a touch more.
The cams aren't really an aggressive grind. The numbers for stage 1 indicate a good street set of cams.

I say raise the compression, change the ignition timing.

But think about this, we don't really want any more power out of the hole...too much white smoke as it is...mid-rpm gains is what we are looking for...too much low-end equals no traction...

SSSlow

There's too much white smoke with a stock setup, yes. It makes a lot more sense to mod the car to put more power to the ground than it does to mod it so that it makes less low-end power.

i would keep your mods to clutch and suspension at this point. your engine is pretty sound.....

Stage 2's injectors are big enough for a 2.8", but no smaller.

moose

i've am already close to 9,000 miles on the car and my clutch has not slipped once yet... i was thinking the same thing about the clutch myself, and trust me my car gets run hard.. i don't know how it has held up.....but i am planning on buying the spec stg 3 clutch and the flywheel as soon as i sale me zx2......

moose

if i decide to buy the pistons from intense racing, what ratio should i buy them in???

moose

for u guys that have already bought the springs, does it still ride smooth, and not alot of bouncing on bumps.......what about the shocks do i need to change them?? if so, who makes a good set for our cars.......

i have bought a set 20" wheels for my wife's hhr so i am gonna take 2 of her 16" steel wheels and put drag radias on them for when i take it to the track....i think i am gonna buy a set of sumitomo tires for my rims in a 225/40 18

NJHK

Your struts/shocks determine your ride quality ultimately. If you are lowering your vehicle with lowering springs, yes, you need to change your dampering system. By lowering your vehicle, you would be giving less room for the shock to absorb inside the cylinder...resulting in bottoming out or easily wearing out. Your stock dampering system was made for your stock spring height, nothing lower.

NJHK

Most would say get a lower compression but your stock compression is fine...can't fully remember but it's like 9.x:1

How many lbs of boost do you plan on running?

juststickit124

Got a pic of that HKS muffler, how does it sound? Is it a Carbon TI or high power?

moose

no i haven't a pic of it yet, butt it has that like buzzing sound to it at lower rpms.... i really don't like it.... i think i am gonna order a different one

Blown 4-banger

9.5:1 is stock compression

OK! I got the upgrades in which I would do if I had your car and some reasons why!

1. Invest in an INGALLS Engine dampening kit 169.99$: that will help with your wheel hop significantly(turbotechracing.com)

depending on if you want handling or the nice grab and quick rev of a clutch/fly.

2. I would go with handling TurboTechracing.com sales a pair of RKsport coilovers for 1229.95$ and jbodyperformance.com sales JBP coilovers for 2294.10$ both are good but the JBP would be a lot better due to the adjustablity of them!

3. As for the clutch: Spec stage 1(494.10$) and ClutchMasters (548.25$) both companies make nice clutch's the spec is just cheaper.(turbotechracing.com)

4. FLYWHEELS: Fidanza 8.0lbs.(329.99), ClutchMasters 8.2lbs.(399.99), Spec Flywheel ?lbs.(395.10$) Fidanza would be the best choice due to price and weight!(turbotechracing.com)

There you have it. those would be the best parts for buck, any questions just write me!
