Well some of you may know that months back i picked up superhatch's old heads with the mazworx cams.
I bought a house a few weeks later so they have been collecting dust for the last few months while ive been working on the house, well house is done and ive been kicking around the idea of slapping them on my current motor but i have to pull it out to do the job and if i have to go through all that trouble i might as well slap together a rebuilt bottom end with it.
So i have a spare good block with some high mileage i want to do up.
first thing , i have all the tools to do this job, i just have never rebuilt a japanese engine, lots of sbc and bbc though.
I have a few idea id like to kick around with you guys.
1. id like to knife edge the crank a bit, not crazy but just to lighten up the rotating assembly, i know ill lose tq, but the car has plenty so ill sacrifice a bit of tq for some more revs
2. rod bolts, last i heard sr20 rod bolts where interchangeable, did anyone confirm this?
3. bearings..... i was able to source a distributor that had a set of clevites in stock stnd size and .25mm undercut. Should i just stay oem or run the clevites
4. clearances, i know nissan motors run very tight clearances, they also love to spin bearings, the sr20 guys are running .0025 main clearnces and .0018-.00020 rods, you guys think that will work for the VH
keep in mind im trying to spin this motor to 8000rpms relativly reliably
and none of this vh45 is equal to a ferrari and gonna cost 1 zillion dollars to rebuild, keep in mind my application i dont need it to last 100k miles, only 10k miles lol
anyway any thing you guys could add would be apreciated
heres pics of the heads/cams/valvesprings and titanium retainers for those scoring at home
