Ok its been a long time since my crx seen daylight from out the garage, and now I want to start rebuilding the car. I know what I want to do as far as apperance but for performance mods im kinda confused. The car is a 1986 crx hf...I read the frequently asked question section and it said get a si long block for my car weber carbs. I understand the carbs but couldn't I just put a si head on my car aslo and that would help?

I want to go with carb setup so i can have that classic look. but also not trying to be the slowest.

Yes, but you would need to update the fuel system by adding in an electric fuel pump. the Si head is a noticable performance bump.

depends on what motor you have, as I understand none of the usdm crx's never received a 1.3 though I am not sure and I am not sure if the hf's got a 8valve or 12 valve head. if you can swing it, I'd say it is EASIEST to just pick up an SI long block and toss whatever fuel/intake sys in there. also keep in mind that the weber setup is quite costly compared to a lesser performing, yet perfect for street driving, CDM carb/IM

All he needs to do to find out what car he has (motor wise) is look at the tag. If it says d15a2 he has the 1.5. If this is the case, we need to ask the question, "When he says POWER, is he speaking of pickup or general torque?" If its general torque, then yes, a motor swap, or even head swap is in order, if he means pickup, then a transmission swap is what he is wanting.

^it'd saw EW2 or EV? since its an 86
might as well swap the whole engine/trans while he's at it. if it is indeed a 1.5 then the best option while keeping a EW engine would be a rebuild... with the $90 ZC pistons, a slight overbore job with honing from the local machine shop, an SI head, CDM DX intake and there you have a slick sub 15 second, 40+mpg street setup
the question is- why haven't I done this? ohh right, I have a B swap

just wondering what C/P with the ZC (PM7 right? - also interchangeable with the P29 D16a1 pistons right? ? ) would give, seems a budget thing that i may try, but would that make me have to run 91 oct gas? thanks.
