Regardless of what you do get you're car tuned for nitrous w/ an engine management system like hondata or a vafc etc...

zex 75 shot + cams = you might run into some ugly issues w/ a stock valve train. Why ? Because you are not running a motor w/ 9.3:1 compression like an "LS". Hence you're valvetrain is going to be strained w/ high duration & lift cams when you are spraying.

Warning to you, agressive cams might call for ruff daily driving :-/

Nitrous is the cheap way out. I would personally save my cash & go w/ a custom turbo kit using primarely inlinepro's stuff & some hondata...

Think about it, sell you're nitrous & that will buy you.. hmmm a tial wastegate & a used bov... lol :-/

Anyways, good luck.

Btw,

7-9 psi on a t03/4 will produce close to 250 whp w/ hondata on an oem h22a.

If you threw some cams in with a nice valetrain & maybe a p&p head by portflow you could prolly see high 200's...

importbuilders has some numbers posted & they all look the same...

most aftermarket vtec cams use the same low rpm lob as stock or a lob that is very close in lift and duration so rough idle won't be a problem, so the only time the "ruff daily driving" will come into play is in VTEC, which i don't think will be a bad thing.

the only role c/r plays in cam sizing is
how long you can hold and lift a valve b/c of the hieght of the pistons and the time it takes to reach the top of the deck.

and for your information, an "LS" has a 9.2:1 not a 9.3

FYI (concerning the "LS")
You are correct, the usdm model runs 9.2:1
The jdm b18b runs 9.3.?:1 (rounded to 9.4:1)


Agressive vtec cams do idle like aftermarket cams to an extent.
For one they bring the idle up from 800 rpms to 1200-1300 according to most posts I have seen on HT.

I have heard of jun 3's (bseries cams) causing higher then normal idle & stall issues if they are not tuned properly.

The point I was trying to make was, do not stick agressive cams in a motor that is being sprayed when it has a stock valvetrain or you might run into issues when spraying at high rpm's :-/
