Whats the difference b/w the two other than 10hp, 2lbs trq and cable tranny? Do they both basically perform the same?

 

they are pretty much the same other then what you have mentioned, for wiring though the 1st gen in obd0 and the 2nd is obd1

 

the gen 1 has the shittiest vtec cams EVER and the gen 2 has GSR cams.

The design of the gen 2 intake manifold is also designed bettter and flows more.

And throttle body...

 

can't forget that 1st gen's are cable while 2nd gen's are hydro. Also the 2nd gen's have 10 more HP then the 1st gen's

 

yes.......

 

arent the internals in the 1st gen head casted wile in the second gen there billet..?

Just the Japanese ones, the US 93+ and the Europeon ones have 160PS, as opposed to the JDM 170PS.

 

also the mounts and mount brackets are different as well as flywheel is for a cable tranny on a 1st gen b16.

 

1st & 2nd gen JDM B16's are slighlty different.

Powerwise though, the differences come from the camshafts, pistons, & ecu tuning/electronics.

1st gen (89-91) = PR3 pistons (10.2cr) 160hp OBD type, cam profiles are rather weak especially on the Auto version.

2nd gen (92-00) = P30 pistons (10.4cr) 170hp OBD1 & OBD2 type, cam profiles are upgraded and are definitely better than 1st gen cams. The upgraded OBD1+OBD2 ecu tuning also helps in the 10hp increase in power.

As for the US, we only get the 2nd gen B16A, we never got the 1st gen. But, just about everything between a US & JDM 2nd gen B16 are identical except for these things:
- US uses PR3 pistons instead of P30's (yeah, we get lower 10.2cr ..woo)
- US OBD1 P30 ecu programming slightly differs than JDM P30 programming, due to compensate for lower octane ratings we have in the US.
- US OBD2 B16 engines added more sensors for emmissions related bs the ecu's programming reflected this change; still uses the PR3 piston though. JDM OBD2 B16A engines don't use these additional sensors; and still use a P30 piston. We never got the P30/10.4cr pistons
