Yes, a GS-R against an B18A/B car with 404's would be a fair race.

There is no "second" stage of VTEC on a B18C. Either it's "on" or "off."

Yes, the B18A/B will idle worse and have poor emissions results, but it will keep up with the B18C for less money. The cam'ed B18A/B is basically like a B18C with VTEC always activated.

u still need to machine ur new vtec head the mounts are different on the "ls"than on the vtec so u have to machine out new ones that kits is just the oil lines so u dont have to custom fabricate any and the head gasket along with the head u need to machine different holes in the head gasket this kit takes all that work out for u but u would still need to have some machine work done to the vtec head

i looked it over and its says u dont have to machine the head due to special dowels they have i dont really kno how thats possible but give it a try see if it works u still need to drill and tap your new oil line and plug the old one in the head tho but thats not hard work good luck

Pulling existing plugs in the engine will work for the oil line.

The mounts are the same.

i dont know its all really confusing if i end up doing a ls vtec swap i will find a bad ass shop for it weither i have to drive to s.a., houston, or even dfw area i will and i will get a hotel room till the work is done, but im starting to like the crower 403's with a turbo, the only thing is that i dont want a super rough idle or any hesitation off the line , and for the price of cams id want alittle more then 15- 18 hp like they say, with the crower 403's and the 404's where does the most power get put in the lower, mid, or upper rpm's? my ls tranny seriously needs some power in the uppers esp 5th.....

403's wouldnt go nicely with a turbo. its an NA cam with lots of lift and duration. your tranny has nothing to do with how much power you make.

i know that the tranny doesnt have anything to do with the amount of horse power that i have, but 5th gear sucks so if i build more upper rpm power then in any gear id have more power as the rpms grow esp in fifth wich is what i was trying to get at, look i dont know to much about cams and all that but i am learning belive i dont just go buy shit for my car i research it and research it that way i know what to expect , i want to go boosted but it is going to take a pretty long time for that so till then, till im ready to i can get a set na cams its all up in the air i keep jumping around on what i wanna do, cuz there is so much that i want to do, i think either 4-1 header is next or maybe a set of eibach springs either prokit or sportline i dont know...so ya i think you just miss understood what i said

if you plan on goin turbo down the road, then dont waste your money on cams right now...build up the suspension like you mentioned until you can afford to booooost it. just my .02 cents...I wish I would have gone that route

Figure out which route you want to go. A header and cams would be a waste of money if you want to go FI. I was going to upgrade my cams but then realized that CA has shitty smog regulations, so I couldn't do that, so I changed my plans and went FI.

If you want more power in upper gears, you should look into a final drive ratio change.

would that mess up gas milage at all ? ya i really want to drop the car like an inch and half in the front and the same in the rear get new control arms, front and rear sway bars.. pretty get a good set up for both road racing 9 cuz its mad fun tearing up roads like spice wood springs and to be safe at the same time0 and something good for drag racing... i will prolly go with eibach sportlines ive heard some good things like that with tegs it doesnt do a extreme drop and if it turns out it does then the pro kit is more for me due to the speed bumps where i live i will get stuck on them
