Project LS Non-VTEC begins.
After installing a stock B20B in a friend's car and tuning it with some Crower 403's and Hondata, I got the bug to build an all motor non-VTEC engine. I needed a stock LS to begin with, so yesterday I picked up a fairly clean 1994 Integra LS.
Today I baselined the vehicle and it made a respectable 120/133. Then we plugged in a Hondata S300 and made a few passes to clean up the A/F and timing maps. The tired bone stock motor made 127/135.
The project motor is off getting sleeved to 85mm, the pistons are on order, the head and the intake manifold are being ported by Import Builders, a stock B20 crank is getting reworked by Castillo, a JDM 4-1 ITR header is sitting in the garage, next to some Crower 405A Non-VTEC cams, so when it all comes together, the car goes back on the dyno for some more tuning. The compression will be in the neighborhood of 11.5:1. More on the project as it developes...

Re: Project LS Non-VTEC begins. (dc-lefty)
ya saying im following this build is an understatement.
howd you get that hump at 3200 on a stock motor, looks like its got a CAI on it...
dont you love that 8 ft/lb dip at 4k you get with a stock IM and cams

Eerie, it's like looking in a mirror isn't it? 
I've got a green 4-door Integra with B20Z and GSR transmission. Although, I've got 403's in my closet just waiting to be installed...so mine is a milder version of your build
..can't wait to see your results

Re: Project LS Non-VTEC begins. (AViciousTHRUST)
sounds like a good built...i had an all motor ls in my civic with 404s crower dual valve springs and crower retainers sitting on jdm itr pistons. but i went the itb route instead of a intake manifold. it was a really nice set up. good luck

Re: (ne3ek)
i just sold a customer a straight LS i rebuilt years ago and never ran. only performance improvement was radiused/recontoured piston tops. it went into a 2000 Si with matching tranny to replace a blown b16 while i repaired some broken guides... and i couldnt believe how great the thing went from idle to about 6,000 rpm with stock intake and ex system, completely untuned.
when the b16 head went back on with a .015" mill, valvejob and some chamber/throat cleanup it obviously picked the power up to 8k or so, but really took a dive on the off-idle torque from the ports getting so much larger.
anyways, nothing wrong with nonvtec.

Removed the stock exhaust manifold, cat, and b-pipe today. Installed a JDM ITR 4-1, straight pipe, and ITR B-pipe today. Thanks to Brian at After Hours for a little exhaust fab work Car feels better, but only the dyno will tell for sure. I am going to try and get back on the dyno tomorrow and see what gains/losses the exhaust change made. Hopefully will be able to start assembling the 2 liter motor next week.

Re: (ne3ek)
Quick update-put the car on the dyno-made a couple of passes to clean up the A/F. Picked up a fair amount of power by replacing the stock exhaust with the JDM ITR 4-1 header, no cat and an ITR B-pipe:

Re: (ne3ek)
Had some free time and did some more tuning. Installed an AEM CAI from my ITR in an attempt to get rid of the nasty LS dip at 4,000 RPM-it worked! This tired little LS motor is starting to break the tires loose in first gear !!!

Re: (b19coupe)
Im curious how you are going to make the new motor work with 405's with 11.5/ 1 compression. You could make it 13:1 to one and still run pump with those cams
