I'm in the pursuit of more power and torque, just like every other Honda Enthusiast. Heres my questions:

This is just a thought:

B18B (LS) Block & Crank
B16A2 (Si) Head - mildly ported/polised
B18C5 Rods and Pistons
JUN Cams, Ti Retainers and Valve Springs (want to use Si Valves)
OBD1 ECU (dont know which one would work best)
Hondata system for fuel tuning

Question:
1) will the LS crank work with the Type R rods?? If not, then what crank will, besides the Type R?

2) What kind of power can I expect from this kind of setup?

I don't expect accurate numbers but an approx. would be cool.
It's either this setup or a killer ass B20Z Turbo setup.

Thanks Alot

One more thing, how many times do I have to change this stinkin userid!! ?? Arhghhh I was up to 600 posts with the last 2 I've had. <---Formerly BronxSi2k

Everything sounds good except one thing...with the type r pistons and rods...make sure you use USDM type r rods..Because the JDM ones have to high of a dome and your compression will be greater than 11:1 which wont run without detonation on pump gas.....Grab the NEW issue of honda tuning...tells you everything about b series motors and frankenstein swaps

I've heard about the compression issues with the JDM stuff, they can get as high as 11.5, but does it really matter? The Celica GT-S runs an 11.5 and it runs ok on the 91 octane from the factory.

What really concerns me is if those Type R rods will work with an LS crank. From what I hear, the LS crank will give a few more cc's over a GSR crank. I think somewhere in the 1810 range?? Which is closer to a "true" 1.8L desplacement.

the type r rods will work with the ls crank and yes it will give more cc's....I dont think the celica runs an 11.5:1 compression ratio..because above 11:1 you get detonation on 91 octane

B18A = 1834 cc
B18B = 1834 cc
B18C = 1797 cc

i just read that the compression ratio for the gts is 11.5:1...how they keep it from detonating I dont know...they must have played with the ecu a lot to do that...but the hondas arnt tuned to run 11:1 on pump gas...so beware

 

[madtownhonda]

ahh....you have to use LS rods (aftermarket or OEM) there and Si valve springs are not going to work with JUN cams

ITR pistons in the LS block (w/ LS rods) with the B16a head will result in about a 11.47:1 CR

What was our compression again? ('99-'00 SIs) Was it 10:4:1 or something like that?

 

[MR2KSi]

From what I've heard you can run up to about 12.1 compression on pump gas, yes even 91 octane. Not usually recommended however. I'm assuming you'd probably have to retard the timing to avoid detonation and do serious dyno tuning for the apropriate fuel maps and ignition timing.

 

[VTECsqznN2O]

mr2ksi...retarding ignition timing would be a must with the compression on pump gas...but oh well
