Re: B18 type R. how to achieve 300hp??
i MIGHT change the cams, im not sure yet.
i only wanted to change small things to strengthen it a little.
ignition items, throttle body, cam gears, small things like that

Re: B18 type R. how to achieve 300hp??
go look up the stats, this isnt a B18C5, this is the JDM B18c which is already ratted at 197hp. it already has a skunk 2 pro series coated intake mani. w/ a race header on it and im putting a Thermal R&D exhaust on it, so im pretty sure ive hit the 200 line mark.
and anyways, i dont plan on building it anymore, the engines fine the way it is, now im just looking to reinforce it a little bit.
maybe a new fuel pump, new spark plugs, little things like that.
the rest of the money is going towards suspension

FYI, The 197 HP that the engine is rated at is HP at the crank, aka BHP (Brake Horsepower).
This will yield about 170ish WHP (Wheel Horsepower). Most people here refer to horsepower in WHP since this is what is measured, and this is what matters more...200whp (~230BHP) in a crx will be very fun and very fast!
If it were me, I would convert the crx to obd1 and get it tuned. Normal "tune-up" items should be done before you swap it in (plugs, cap, rotor, timing belt). A "better" fuel pump will only be beneficial if your current one cant keep up.
Leaving an ITR fairly stock is a great idea. A few bolt-ons and a tune are all they really need. Good luck!

Re: B18 type R. how to achieve 300hp??
Even with your "race header"and Junk2 intake manifold I doubt you'll be making over 180whp, which is how horsepower is measured among this community, so drop BHP. Sure, technically my d16y7 makes 110hp. But it's got 180,000 miles on it and that's BHP, after the miles and the drive-train loss I probably make ~70whp.
Edit: woot, 14,000.

yeah i plan on keeping it stock and just upgrading a few components for a better tune.
what would the obd1 conversion do?? and what would i have to do to it?
would it even be worth the trouble??

"C16™
Used in turbocharged engines, blown engines and nitrous applications with CRs up to 17:1. Recommended by the top nitrous oxide companies. Spec Fuel for NHRA Comp Eliminator."
"Q16™
Q16 will work well in any drag racing application -- naturally aspirated, nitrous or blowers.
Q16 is highly oxygenated, requiring a 4-6% increase in fuel flow, which will make 3-5% more power than competitive 116 octane fuels. Q16's oxygenation will significantly expand the range of air/fuel ratio acceptability, so performance will be more consistent and won't vary as dramatically with altitude or density changes. For bracket racers, variations in ET from run to run will be substantially reduced. This added fuel flow also effectively increases its octane by 6-8 numbers above its standard ASTM octane rating."

I'm not a sales man, but i'ma put it to you like this.
Good bolt ons, and a valvetrain/cam upgrade should easily yield 200+whp in a stock ITR..which will overall be a fun car and pretty quick, specially in that chassis.
You will need cams to break 200whp on that motor..

My point exactly and the OP seems to have been over-zealous from the get go. I've gained the impression he's young and new. I remember having unrealistic thoughts not so many years ago and doing similar things on these forums.

Re: B18 type R. how to achieve 300hp??
If you have a built LS engine... why not take the LS crank and Eagle rods from that application and add CTR pistons?
It's obvious you're on a low budget build so use the resources that you already have. The JDM type R 4-1 headers are pretty good (if that's what it has on it). Add aftermarket valvetrain just for safety specs, muffler, port the mani to 65-70mm with a matching TB and you should make 190-200whp and have the tq to back it on your higher octane gas. If you could get your hands on some CTR cams that wud be even better. Tune the hell outve a obd1 ecu and you'll have a pretty fast engine in a hella light body.
I have a friend with basically those same mods plus pro2s and he made 216hp on our crappy 90 octane gas here.
