if you got an integra block. the only way you would have a crx head is if it was a jdm b16 head? is it dual or single overhead cam?

If it's LS/Vtec then you need a LS/Vtec tune to pull the power out, that would be possibly why you only ran a 14.9 or whatever at the track.

You might possibly be running like Allex and if so then your cars potential is hidden from not having the right pistons in the block...That's if you are running a b18 block with a b16 head cause your power drops off at like 7200rpm's instead of 7900rpm's.

Post your heads part number, your blocks part number, your tranny number as well and we will see what problem is happening.

Post up the casting number of your head and your engine code on the block and This will help us see what you have. The PR3 is the SiR ecu(in OBD0) form. That would be the b16a. Also keep in mind the PR3 is chippable, so it could have a tune on it.

I have LS/Vtec tunes and plenty of good b16a tunes here if chipped.

it's a b16a.

block #-1405440 ( i read that all the b16's that start with 1****** were from integras could be wrong though )

head #-PR3-1 Hm

tranny#-YS1

So it's a obd-0 block with a obd-1 head? I do beleive the obd-0 came with just PR3 stamped on it and the obd-1 Came with PR3-1 or PR3-2 depending on if the head came off a B16a1 or B16a2.
