Gents, and Ladies (of course),

I'm looking for opinions on my ZX3 build-up. I intend to run the SVT intake system, FR2 cams with adjustable cam gears, SVT header with 2.25 back, 8.5lb flywheel, decked and ported head (amount of decking/compression still questionable), and the Xcal2 dyno-tuned. I'm hoping to be between 150 and 170 WHP, do I have a chance? I'm very new to tuner cars so be blunt if you must. Feel free to offer suggestions on other build-up tips and guesses on what my actual WHP will be. I'm not ready to sink the money into FI, maybe next summer.

Thanks,

Update, I am now going to go with SVT pistons and rods to increase the compression. I will still deck and port the head, but the porting may be done by my own hands so I won't include that as a positive with regards to performance. Am I correct in believing that the SVT rods/pistons will bring me up to just under 9:1 compression? Thoughts quickly will be appreciated so I can pay the man for his SVT loot.

When are you having your cams done? I'm probably going up there sometime over the next month again.

I'll check out that site tonight when I'm not at work.

And thanks for the tip on the drag strip. I'll keep that in mind while getting whooped. Will this car, stock, beat a pretty stock Civic?

Let me know how the 3s work. I use this thing as my daily driver and I plan on taking it to Washington DC (12-13 hours) in August so I want it fairly smooth (although I could put the stock motor back in for that trip).

Thanks for the other tips. I'dd address them as money allows. I do plan to port the head as much as the flow bench tells me can be done. Is it true on these heads that intake valves don't make much, if any difference? The guy told me that almost all of the 4cylinder, 4 valve per cylinder heads only need exhaust porting. Another thing with decking the head, at 10.5:1 will I need the stronger rods? What is the barrier for running regular gas versus high octane? I'm guessing around 9.5:1.

Keep the suggestions coming, I need all of this info and plan to keep coming back to this thread for the next year or so if it keeps growing.

Nikiter, what's the deal with Foci up in Canada? I have a machine in Windsor that we installed a couple of weeks ago and every other car on the road was a focus. A ton of ZX5s too. I felt right at home up there (except for the border crossing).

I forgot, I have the UDP too (crank only). It's out being hard-coated right now and will hopefully be back before the weekend.

The dif is too rich for my blood. I am running on fumes already and the real work won't start until hopefully tomorrow night.

Any thoughts on decking the head? How much, how much compression will the stock rods handle?
