Hi all! I just got a 99 prelude base model (dirt cheap) and it had a dropped thrust washer. I was wondering what you guys think I should do based on cost and down time.... One option I was considering was to have the rear thrust surface on the block and crank machined and polished (all burred up from crankshaft self machining), and then ordering a thicker custom made thrust washer to put it within end-play specs. I figure since it will have been machined, the lip where the thrust washer sits that has worn down will now be a little deeper and actually be able to hold the washer in there. But yeah, 2 main caps are a little worn as well from self-machining crank, but it looks like it could still hold new bearings pretty well, but is there a way to weld in more material, and then machine it down back to spec? oh yeah.. my dumbass already went out and bought new standard size bearings(ACL) for this too...

The other option I have is this: I just picked up a 96 F22b2 block for 150. The guy claimed it only had 80k, and it does look pretty good... even has the honing marks in the cylinders still, I just gotta e-z out a broken crankshaft pulley bolt because the previous owner thought it would be fun to change his own timing belt using a large prybar on it, and turning it clockwise to remove it haha! But anyway, I think this block even has a knock sensor on it (96 and up =OBDII). I've read lots of forums of people sucesfully mating the f22 block to the h22 head (prelittlelude), and I think it would be a cool idea to be able to throw some fat boost on this later on... I might just need some slightly higher compression pistons and the other little odds and ends people use for this frankenstein hybrid....

so please peoples!!! gimme a shoutout with some good suggestions to get my *** back on the road! my fat-*** already bent the rear axle on my MTN bike!!

I'll try to put up pics of the h22 block/mains/crank later today for your evaluation.

**bump**

anyone? maybe I should sign up at a DSM forum... They'll know what I'm talkin' about!

 

 

If your going to do the H22 head on the F22 block would you want new pistons if your looking to boost it? 8.8:1 CR is a pretty round number for boost isn't it. But with the H22 head on there you'll probably end up around 8.3:1 with the 53cc combustion chamber. Oh well deck the block and mill the head..lol Oh and FYI the F22B2 does not have a knock sensor in case you need one you will have to drill and tap a bung for it. Remember your loosing 2mm of bore with the F22. But you pick up approx. 4.3mm of stroke if that's what your looking for.

 

yeah, would definitely like to get higher comp pistons. What other series motor pistons would be compatible with that block and rods?

 

Tell ya honestly I don't know of any right off hand. There could be some oversized B20 pistons that might work????? I'm going to 87.25mm for my b2 build so that I have a better selection of pistons.

 

Hi all... well, I have some good news, in case this happens to any of you... the machinist said, that yes, he could resurface and polish all the thrust surfaces, I think hes using a line boring machine, crank grinder and polisher, and a crank thrust surface polisher... so we should be kosher with that.


And here is the link for the company that I'm gonna use to make me custom thrust washers:

now I can save that f22 block for my 88 4WS! mwahahaha!!




Now I gotta do some serious block and head debris removal before I can even think of getting started on putting this thing back together!! DO NOT want this to happen again!!!
