Cam will provide MUCH more power then rockers, and you can shift hte powerband up for a better high RPM torque. You have more then enough low RPM torque with that car, so for racing, higher RPM is what you want. Hell, it'* what you're in the entire race after 20-30

Do you want straight line performance, more turning performance? Endlinks are $20 or less, and REALLY make her turn.

I agree that a cam is probably next for you, and will give you more mid-high range. That'* where the series 1 lacks.

And handling performance (endlinks are a good start) including struts are great, but with that extra power and removed top speed limiter, you need to SERIOUSLY look at upgrading your brakes. Trust me on that one.

Perhaps some more cooling is in the works? A ram air feed to your airbox and some external cooling for the SC would help squeak a wee bit more out of the top end.

adds cam to wishlist...

already have performance endlinks, car came with em...

not really looking for handling performance, more get up and go kinda thing...

brakes as in just new rotors (which they are), and pads?

im also looking at getting another tranny cooler, how do the ones on ebay compare to elsewhere?

Have a transmission buiilt up to handle the power. If you are having tranny problems with the amount of power you have now, you need to do something to handle the power. Otherwise you'll just have to keep putting in more trannys.

Another good mod would be to put a block of wood behind the gas pedal.

It'* a bad sign when the cop pulls you over and says, "Hey Andrew, it'* only been 24 hours!"

Yeah a cam will make for a great start, albeit more work involved. Porting your heads also make for a great gain, and you can do them yourself if you're comfortable with a rotary tool.

*shameless plug below*

If you're interested in a pulley I'm actually having a bit of an unannounced sale, $55 for whatever size you want. If you only want to go down to a 2.55 I'll sell you my old stocker at a great deal if you want.

As for the transmission, just a cam probably won't make it necessary to upgrade but if you plan on a large cam with porting, exhaust, and a pulley you may want to consider it. As for that, you can try your local shops or:
http://seriesoneperformance.com/transaxle.html

That'* the lowest price you can get on it. Might be one of those "wait till it explodes" pieces, but I was too scared it would leave me stranded or puke parts into the side of my block to not upgrade.

Andrew, if you do go with a cam you will be able to drop another size or two smaller.
Also, hae you put a high flow cat on? If I remember correctly you haven't. I'd suggest checking out www.justmagnaflow.com for a nice flowing unit at a very reasonable price.
Also if you are going to do the cam, I highly recommend you get a pair of heads from a yard and port/have them ported while waiting for the cam to come. The cam will flow even more and you will not wish you hadn't done it.
If you aren't comfortable doing it yourself there is a GP guy in Alexandria who has done 3-4 SII L67 heads/mani'* and everyone who had work done by him is all praises. He quoted me like $200 for the heads, intake and exhaust mani'*, but since the SI'* exhaust mani'* don't necessarily benefit from porting you might be able to get it done for slightly less.

Intercooler!

A cam at 119k? maybe because the engine is already out but it is prob. better to got with the rockers.
