Well, after the fun we had with the RS-WRX conversion, I felt it was time to tackle another conversion.
My OBS has been a little lacking in the low end ever since I put on the big tyres (215/75-15 Grabber AT2's) So I waited and waited and waited until I was able to get my hands on a 2.5 litre engine. Finally got a block a few weeks ago so I sent out the heads and cams for a little work. I had a local shop do some light headwork on the heads with an emphasis on low end power. Sent the cams off to Delta, again emphasis on low end (unfortunately they only have one profile for the 2.2 cam :icon_frown: ) Anyway, finally got the bits back yesterday so I started the build this morning.
Pulled the old engine out, surprisingly good shape for 275k on it, very clean inside (o.k, not really a surprise being it has been maintained to the mile with factory parts since day 1). Being that my chain fall is broken I had to strip the engine in the car and remove the block by myself (I am all that is man!!!!!).
Had to stop there for the night, I'm tired and the wife wants to watch some movies (and I have venison jerky to make!)
I'll add some pics tommorow, hopefully it will be on the road come Monday.
Based off the prior ones we have done it should be around 11.5:1 compression. Never had one with cams and headwork though, so I am very curious about the results, no more 87 octane for me! :biggrin:
