what is major differences from r32 rb26 to the r34's?

i would only like to know info in regreds to engine ie block, pistons, camshafts etc...

i will keep looking for info but many thanks for any info provided

[ATpossible]

okay i found this...

The R33 engine also introduced a mechanical advance on the intake camshaft improving torque slightly

not sure how accurate this is nor do i have any more info on this particular spec improve

got this from freshalloy...

all had 240 int / 236 exh duration and 8.58mm int / 8.28mm exh lift

sounds kind of like a contradication to the previous post. can both be true?and are they?

i'm continuing to look but im running out of time cuz class starts soon...anyone have anything they would like to add please

[ATpossible]

bringing back my own post from the died...

i think i remember seeing a post once on visual differences of rb26 engines between r32 and r33.

Can someone please let me know of a easy way i can tell if i have a r32 rb26 or a r33 rb26?

thanks for your time people

Crank Collar issues on the earlier versions, the later versions got the fix

[ATpossible]

no not that. something visual or something that is only on one or the other because my crank collar was good but i was told it was a 95, but that is was a r32, which would make it a r33 engine tho if it was 95 year?
