what compression ratio did they end up getting?

today i made water injection for my car (i know i am veering off subject a bit), and i want to make the compression ratio around 10:1 to 10.5:1 (ish) so if anyone has shaved a bit off there 4k head, how much did you take off and what compression ratio did it end up being? cheers

you would be surprised, one of the guys i know there owns a honda CRX, 11.5:1(ish) compression ratio, 156hp @ the wheels, very fast i reackon i'll just stick with my good old 1300...

what year and model are 4e-fe's out of?

i've put electronic ignition out of a 5k in it and i noticed a little difference, then i got addicted... i see that in every ones opinion putting a dohc head on my 4k would be hard and annoying, but i'd like to do it (and potentialy make a 4kg-c)

the problem with putting a 4age in is that i'd have to modify the engine mounts, have a new gearbox etc. the other main reson that i want to stick mith my old 4k block is that i want to start hillclimbing when i get better at driving and i don't really want to go up into the 1600's class, staying in the 1300's (that i think there is) so if anyone out there has a 4k block/motor and a 4age head/motor, and they could check the bolt pattern i would greatly appreciate it :(

what i was going to do was take the 4k head off, make a new timing chain/find a belt, take the lifters out so the original cam is only driving the dizzy and put on a 4age head (for example). my dad ( a mechanic) and i had worked out this plan only this morning, so we're not too sure of what dohc, in-line 4 heads toyota make and what would have the same bolt pattern. it should work, if there is a head like that out there :( and by modified, i mean no engine enlargments, turbos, or anything that you would have to get an engineers certificate for

With me only being 15 and the new laws in nsw saying that i couldn't drive around in a modified car, my dad suggested that i put a dohc head on my 4k, seeing as most other brands of engines can swap heads eg. subaru 2.5l with 2l and ford 1.8l and 2l heads i was wondering if there were a toyota head with dohc that would bolt straight up, without too many modifications. i was hoping that a 4age head would bolt up seing as they're relitivly cheap in comparison and would be easier to find max
