sohc bottom with a dohc head and sohc ecu...

I guess i got bored, and figured I’d try and build my first motor, haha.
I thought about trying the supercharger route but decided to cheap out go the high compression route.
I used the 8.5:1 pistons with the dohc head, which my understanding is supposed to result in 11.1:1 cr.
I had to modify lower timing chain tensioner from the sohc to fit, the dohc tensioner won’t work with the lower timing cover.
I also had to modify the lower tensioner guide from the sohc to fit.
Brendan and I started the motor up few hours ago, and aside from my base timing being a bit off, it ran great. It even idled beautifully.
Thanks to those to helped out, especially Brendan who helped greatly with with actual swap, and Graham who helped with getting a bunch of the parts.

I’m going to fix time timing tomorrow though, I don’t feel like pulling the oil pump off tonight :S.

The block I started with.

The cylinder head I used after coming back from the machine shop for cleaning and decking.

looks good mark, did you get the timing set yet?

I’m lazy and in no rush. Maybe tomorrow I’ll fix the timing haha.

thats awsome!! good job!

soo no power steering?

No power steering is right, haha.
I don’t mind it that much actually.
I finally got around to sorting out the timing.
She’s fun to drive now, fair bit torquier.
I packed the motor mounts with PL construction urethane adhesive I think it was called. Pretty much like solid mounts now, and I got used to those after bout 20 mins, but yea much more vibrations lol.

wow this is sick, put it on a dyno asap!

can you take a picture of the urathane you used? also where can you find it? thanks

what did it cost you to have the head machined?

$60 for cleaning (washing and bead blasting, it was a dirty mofo, with a some really caked on carbon)

$60 for the machining (kinda needed it after the bead blasting lol)

A nice little project, thanks for sharing!

It really makes me want to build a bulletproof block on the side to drop in my car for some psycho boost #'s… :smiley:

eh elroy after u did work to the engine and had everything done, how did the engine perform? Did it last for a long time? Any mechanical problems? Difference in fuel economy?
