IMHO, I'de save up some extra money until you're able to get the cylinder heads ported and polished, get an oversized valve job w/ stainless steel vavles, competition vavle springs, and then add the cams to that. You might as well do it all since you're going to have to strip the motor down to the heads just to get the cams out. It would be a good idea just to finish off by pulling the heads and doing it all. VTengines is a good place to get cams from as they make the best from what I've read.
Uh....what? If I hadn't changed my valve-springs, I could have had the cams changed in about 2 hours.
With the AFM cam chain tool:
- remove the valve covers
- move the p/s resevoir
- break the bolts loose on the cams
- remove the rockers, insert the tool
- change one cam
- move the tool to the other side
- change the other cam
- torque cam girdles
- bleed lifters
- re-install lifters and rockers
- install valve covers
- bolt p/s resevoir back into place
I'm sure I may have forgot a step, but changing the cams is not rocket science. You don't have to tear your engine down to get to them or to change them. Changing the valve springs is a PITA. Its not hard, but just takes time and lots of patience. And, YES you can do them in the car with the OTC valve spring tool, an air compressor, and a hose to go in the sparkplug holes. Again, its not rocket science and you don't have to strip the motor down.
As for results, I have Comp Cams XE270AHs. They are what people refer to as Comps "Stage 2" cams. I'm not sure how they compare to VT Engines Stage 1 and Stage 2, but to give you an idea my car has:
- C&L Plenum
- Accufab 75mm TB
- Mac LTs
- Trubendz o/r X-pipe (bent by Ray Charles, will probably get replaced)
- Comp Cams XE270AH cams
- Comp valve springs
- Magnaflow catback w/Spintech mufflers welded in
- Steeda CAI
- Steeda UD pullies
- Dynotune with Pro-M software/chip
- 290hp/~300tq
My car did fine with 19# injectors. I have heard though that somewhere around 300-320RWHP they will "max out" and you will need to go to 24# injectors. It is supposed to be better to have a larger injector acting like a smaller injector than vice versa through the tuning. Also, IMHO (and they're like a-holes everybody has them), I would take a dyno-tune with a good chip or reflash any day over one of those handheld tuners. Take it to someone that has done hundreds of cars and knows what they are doing. It would be fun to learn all the parameters, but I'd rather have the peace of mind that someone that knows what they are doing tuned my car. Not saying you aren't capable of learing it by any means, but how many times is it going to take to get it right? I'd rather be out driving it and having fun instead of playing with my "little plastic box with buttons and a cord".
