Anyone know about the compatability of using dual cam heads from a WRX?. Also is there any design difference between the RS block and the STI block besides the componants?
I was thinking of using a fully built 2.5 shortblock (probably 9:1) with wrx heads, custom cams, and start off with a stock wrx exhaust, turbo, intercooler etc..
Any feedback?

new question....
1) what kinda compatability issues will i run into if i use a turbo kit on my 1.8 that was specifically designed for the 2.5 ( i.e. AVO )
2) what boost level should i run with the stock compression ratio? ( since its 10:1, i believe, idont think anything higher than 7 psi will break anything..
3) i have 90,000 miles... anything i should do before installation of a turbo kit?

1) Nothing major provided you get the one for your EM style, i.e MAF vs. MAP. I would recommend getting an RS hood and springing for a kit with a topmount.
2) The lowest boost you can run on the wastegate of the turbo you are getting.
3) Make sure every component of your fuel and ignition systems is in tip-top shape, and start saving for the inevitable meltdown. Might take 60-80,000 miles, but it's definitely going to break sometime with a turbo kit.
