i have a fully built 99 si with all toda products but i have absolutely no torque. I'm going to buy a new block but I'm not sure which one, what do you guys think? Is there a b20 block that's made for vtec, I'm not trying to run LS/vtec or b20/vtec. I was also considering a c5 block if I can get my hands on one. A couple other possibilities is a c1 block or a stroker kit! What have others done? Would dropping in a set of ctr high compression pistons help that much? Thanks guys

 

To increase torque you need to increase displacement.
If you don't want to do the lsvtec or crvtec I would recomend the gs-r block and stroke it and bore it.

 

a supercharger would do it

 

i cant supercharge it, i have a fully built head with toda products. They are made for all motor.

Why stroke a b18 block when i can just stroke the b16 block to the same displacement? You can stroke a b16 out to a 2.1

 

i heard stroking and boring a gsr block makes the wall thin. heard it doesn't last long. give it a try if you have lots of dough laying around

 

Boring out a block makes the walls of all engines thinner. Yes you increase displacement but you do that by lossing integrity of the wall.

In all seriousness, its not the engine... its your car. Your car weighs about 2700lbs plus you and miscallenous things in it. You're talking about at least 2800-2900lbs. I dont see how you would feel anything if your curb weight is that much.

I dont know if your talking about dyno tuning torque or if you are talking about "butt dyno" if you are talking about butt dyno, I think your weight has alot to do with it, but if dyno tuning... then its a different story.

When you say built... be more specific in terms of built. I could put cams in my car and say its built... no pun intended.

If you are craving for torque or neck jerk, drop your engine in a 93 hatch and it will rip. My cousin has a B18 all motor dyno tuned at ~210whp in his hatch with full interior 12.9sec 1/4 mile.

wouldnt stroking keep the cylinder walls the same since your not boreing it out your just increaseing the rod length. I know when you stroke a chevy 350-383 it only increases rod stroke length and you notch the bottom of the cylinder a hair to clear rods and would think this idea would apply over to a honda. Also a honda with torque? Whats that..lol. Turbo would add torque as would a super charger. Bigger displacement usualy is what makes torque. Ever notice how diesels make liek gobs of torque and they usualy have huge displacement. Its really hard for our lil engines to make lots of torque and still be streetable.

Your completely right, you just lengthen the stroke and in result creating a larger displacement. You don't weaken your walls because there is no boring involved unless you go with a larger piston. Many, if not all, 'stroker kits' don't require you to bore out your walls. When you stroke your block, you might as well sleeve it too while its out. I mean honda blocks are aluminum, the iron sleeves allow you to push alot more.

My car weighs 2360 lbs with me in it. No A/C, no P.S., no CC, no tar **** underneath the carpet and nothing in the trunk.

As for my motor...
Toda spec B cams
Toda valve springs
Portflow retainers
Toda cam gears
Toda timing belt
Mugen ecu with a 10k rpm
j's racing intake
ITR header
jun lightweight flywheel
clutchmaster stage 3 clutch
msd sci
vafc
gsr tranny
and last but not least the tanabe g medallion exhaust

 

interesting.... Uhm... can we just say it is a HONDA motor? What are you comparing your torque to? a VIPER or another similar setup?

 

sell that motor and build another one for boost ?

 

like everyone else is saying....if you don't want to go FI then I would just get a B18c block and build that.
