Anyone have a 2.7 with just i valvespring, i camshaft, i intake and TB dyno results to compare to m20curtis's? Mr. Anderson maybe?

dead thread come back to life.

ive been thinking of doing the 327i thing. stick on an i head, i intake and the computerto my block. but is it really that easy? and what would happen if you swapped out the computer from my super eta and put in an i computer?

I head on ETA bottom end = 8.42:1
I head with I piston ETA rod and ETA crank = 7.97:1

those are nominal numbers

do you have a SETA? If so the cam and inner valve springs are the only thing in the head needing to be swapped to make it a I head and at the same time a good refresh will help things alot

how do i know if i have the SETA? my car's title says its a 325/e and the rear badge says "325" and its got the "is" accessories on it. never owned an eta so im not sure

they were only sold in the 88 model year - if your car is an 87 it's just a regular eta.

The power loss is bogus, it was posted on here last month I think. Some dude in toronto did the swap but he used mega squirt, it made 130hp or something like that I think.

Edit: ^^ thats it.
