supercharger for a b18c5

Does anybody know where I could purchase a supercharger or turbocharger for the B18c5 (ITR motor)??? Or if there is any way I could purchase a HKS Twin Charger??? To use both the supercharger and a turbocharger??? Hit me back, later.........

F/I on a c5? thats the worst idea you could ever do.

Thats like paying thousands of dollars extra for special parts, then paying to have them removed, then paying for new special parts then paying to have them installed.

Dude, you're insane if you wanna try to turbo and supercharge your ITR motor. HKS did it but it's mainly for show purposes. and remember, they had to do about 3+months of testing and adjusting everything so that the motor wouldn't blow. it's not a direct bolt on part and you wouldn't benefit from it. another thing is, with the high compression of your ITR motor, you'd probably be only able to spill out a good 5-6 psi. any higher and you might risk destroying your motor.

again with the compression..:(

yes the motor was built for N/A, but when you compare a B18C5 with 8psi and a B18C1 with also 8psi, the ITR will be faster no doubt. 10.6:1 compression ratio isn't considered high. it seems high because most of other honda engines run on lower compression. you can pick up a B18C1 for about $3200 and a B18C5 for $5000. whats the difference? the B18C5 has a tad bit higher compression which will help yield more power from the same boost (and other benefits), better cams (more airflow), factory port and polish, less restricted manifolds, etc...

when you work out all the parts you would get at the auto shop, it turns out to be the same. lets see..$3200 for the block+$1000 for port and polish+cam=$500+etc...it'll add up to the B18C5 price range. in the end..you're gonna want to do all those stuff to the engine anyways, so why not just start out with it?

also..whatever parts you need on the B18c1 you'll gonna have to get it for the B18C5 anyways. only if i can remember the guy who ran 11psi on his stock block B18C5, he would sure like to explain everything. you benefit a lot from going with higher compression engine.

1. quicker spool-up
2. more power when off boost
3. turbo has to spin less in order to gain the desired power(longer life)
4. more potential power

compression is what makes power. if you lower it..you're taking the power away. and if someone say you can raise the boost more..you're just adding back the power that you lost during the lowering of compression. now lower compression does have its benefit. you get a larger margin in making errors that could potentially kill the engine. thats why its so important to tune your car. if think lowering the compression even more will result in a very big margin so that you don't have to tune it..then don't even touch a turbocharged engine. turbo requires tuning. plain and simple. if you still believe in lowering the compression..by all means go ahead. have fun running 7.0:1 compression pistons at 6psi. that is about the same amount of power as a stock block will get, but it will still be faster since it has the power at low end, which the lower compression doesn't have until the long wait turbo spool up begans. but then again..its not my car:D

no compression is not power. timing is power! you can have as high as compression you want. but how much timing can you run with it. w/o detonating. High compression & boost sucks unless you can find 118 oct gas at your local 76 station. yes to low of compression does suck. but using lower compression pistons w/ booost make the car alot more streetable. b/c if you run high compression and 8-10-12psi you have to run like 6 degrees timing wich feels like pure dog SHIT. so to make it feel better you bump up the timing,start detonating and what do you wind up with low to no compression because you have no rings left. trust me done been through that. but to the guy trying to boost the itr motor i wouldnt ive seen alot of people try and most of the time it is a joke. i have seen a b18c5 in a hatch supercharged W/ a ? shot of NOS it was not a quick as you would think. i would definatly go all motor those are good motors build em:smoker:

true dat!:dogpile:

u increase compression, you get more power..you lower the compression..you get less power..see the pattern? and yes, timing does get involve, but saying compression isn't power is like saying airflow isn't power also. also..i never said you should run high compression. high would be considered 11.0:1+. would 10.2:1 be considered high? even when so many people have ran 15+psi on stock internals and such and never had a problem? just don't expect to run 12.5:1psi with 13psi on pump gas. 10.5:1 is usually the best ratio for tuning and power making.

most of the people who builds up B18C5 and try to go force induction usually don't know what their doing. only some of them actually do a good job. i don't know how the guy in the hatch was driving, but a friend of mine has a 93 civic hatch CX with a B18C5 on 10psi and runs 11's with traction. no major build ups. just stock internals and the minor stuff.

many B16's and B18C1's i see have stock timing and tun 16psi+ without any problems. its all up to the tuning.

I would really like to see a b series motor ..no wait any honda motor run 16psi and stock timing. No better yet let me see YOU run16psi with stock timing. *that has stock internals.:bloated:
