Re: LS vtec monster in crx (crxdude4675)
I'm going to tell you from experience because I drive an all motor LS/VTEC CRX.
First, my build is quite mild. PR3 (B16) H/C pisons bring the compression to 11.2:1, fairly high, but if you expect 225 whp, you're going to need a lot higher.
To give you an idea, with crappy intake and crappy exhaust I put down 161 whp untuned. Even with top name ****, J's or AEM Intake, Invidia Exhaust, and some 4-1 2.5 Collector Header, I wouldn't expect more then 185 whp once it's tuned.
So that's still 40 whp short of your goal.
To reach 225 whp, you're going to need not only high *** compression, but a fully reworked valvetrain, (CTR or better) with some very pricey cams. Not to mention a top brand intake manifold or individual throttle bodies, a very nice port and polish job on the head with a nice valve job. I would guess that with all those you're going to be sitting around 200 whp. Of course with that high revving of a valve train, expect revs of upwards of 9 grand, so you're going to definitely need some ARP Rod Bolts.
20 more whp to go.
Expect to now need some sort of fuel delivery system that can perfectly fit your needs. Not too bad, if you're really good with tuning you can use something cheap like a chipped PM6 with TurboEdit (what I use). But if you really want to get ever ounce of HP, you're probably going to want to go with something like AEM EMS or upgrade to OBD-1 and use Uberdata. More money.
In the end, I can't honestly say you're going to hit 225 with a modest NA set up. Pistons and Rods are probably going to be required. In fact I doubt you can do it for under $5,000 into the motor.
Best transmission you're going to get would be an ITR, or at least the final drive from it... but that means you're going to need to go Hydraulic which requires a conversion kit which is more $. I would just get the B16 with LSD, and have it reworked for ITR Final Drive.
Either way... You'll have a ******* awesome motor and a hole in your pocket making you say "Hey, why am I still driving a CRX?"

who said he wanted whp...
he probably thinks 225 is some magical number that will make him happy...
build up a reliable ls vtec...
or a high compression b18a and let him enjoy some modest tq he's been missing with the 1.5 of his.

what are you talking about h22a with that **** you listed MIGHT make 200 maybe and he said he wanted to build a lsvtec. if your looking for a tranny get they ys1 92-93 gsr cable tranny and put in the ITR final drive

unless you got the hook up or know how to custom fab urself there is no way u can put an h22 in an ef for 2g's

Re: (atomikpunx2)
Let's try to stay on topic people! He said LS-VTEC let's share our knowledge instead of bickering about H22 pricing and H22 bolt-on power.

I assumed he meant whp because he said he wanted it to make that much horsepower, and unless he's psychic he's only going to know whp from a dyno.
Either way it's attainable. However, I very strongly don't recomend going with a high-compression B18a.
First off, high compression motors are expensive to build, and you are starting with jack **** if you're using just a regular LS. Do you realize how much would have to be dumped into an LS to get it to be a good NA motor. Your starting with a **** valve train and no compression.
If you're going to spend the money on a B-series swap, and you're staying NA, you're a moron if you go non-Vtec. Torque is great, but horsepower wins races. You are shooting yourself in the foot if you leave that LS head on an NA engine.

true that...if u r gonna stay non vtec go with the b20 head...better flow u will see noticable gains for sure...but i would still go with the vtec head

Once again NO! Do not go non-vtec head if you're going NA. Do not listen to this guy. The B20 head is the same thing! The only good B-series head is a VTEC head!

dont talk **** fool...if u can read i clearly say that vtec head is better...b20 head has larger intake ports and will yield better results...i would never go non-vtec for n/a..unless u throw in those toda vtec killers

"Dont talk **** fool?" What is your deal?
Do a search the b20 head is the same ******* head as on an LS. It's even stamped the same on every single part!
It may have some microscopic difference in intake runners but it is a TERRIBLE head! You are recomending someone who already that head (on his LS motor) to go out and WASTE his money on a B20 head. That is 100% BAD advice.
So don't give me this tough guy attitutude. I'm the one trying to help him out, giving him an experienced stand point (I have an LS/VTEC IN my car with his bottom end and I've been in his shoes.) and you're telling him to throw his money down the drain. Stop giving him bad advice and I wouldn't have to step in and correct you.

How the hell is he supposed to Stay SOHC using a b16a tranny?
For the last time let's just help him get what he wants instead of telling him he's wrong with what he wants or steering him in the wrong direction.
