Building another SOHC
Now that I have a spare SOHC block. Im thinking about buying a 90-91 hatch and transplanting the motor.
I would like to sleeve it to 1.8L if this is even possible. Possibly stroke the motor down the line.
This will kind of be my toy for a while, so I guess I can play with it and see. What kind of abuse can D16A6 rods take? I wanna go cheap and efficent. With decent power gains. Im gonna go with turbo on it, since I have such great luck with turbo. Where can I get sleeves, and what size do I need to achieve this? Also, what pistons would I need then? I'm planning to run a good amount of boost on the motor 15-20psi. I would like to run stock internals, other then the A6 rods. Maybe even drop a 75 shot wet kit on it just to push the limits. Does the D16Y8 block mount right into the early 90's hatch? What else should I be looking to obtain? I just want to test the limits of the SOHC motor before going with a DOHC. I would like to stay away from aftermarket pistons and such. Because Im not trying to spend alot of money on things that won't be interchangable w/ B series.

you can sleeve the block upto 78mm but for high boost application's you might just want to go 76mm(stock is 75mm) so the wall's are thicker and can handle more boost.
and you don't want to stroke it the d series already has a bad r/s ratio stoking will only make it worse.
LS rods have the same length and big end diameter as d16 rods (but much beefier). B.E. width and pin diameter is different so the rod will have to be machined and bushed to fit.
a good set-up for you is the y8 bottom end with ls rods, y8piston's, a z6 vtec head because it will lower the compression, and a homemade turbo that won't cost you very much and will run pretty good in a ef.
if you want a better set-up get a y8 bottom end, ls rods, forged pistons, y8 head, t3 turbo, dsm injector's, big fmic, a vafc , fuel pump, afpr and alot of tunning.
best set-up golden eagle sleeve's, forged pistons(je, srp), forged rods(crower, eagle), stainless steel valves, arp head studs, dsm injector's, big fmic, fuel pump, afpr, convert to obd-1 and run hondata and alot of tuning from ss.

Im not going with anything aftermarket for internals. Like I siad this will be my 'play' motor. Before going hybrid. It will have a z6 head, dsm injectors, pump, obd1-hondata, t3, intercooled, custom manifold+downpipe+external wastegate, 255lph fuel pump, y8 stock bottom end, MSD, head studs(Can't get these w/ y8 ), rod bolts, open 3" downpipe. *thinks* Anything else Im missing?
I think I can get this setup to 12-15psi stable everyday on pump gas. Although It's just a guess. Cuz max boost Ive run w/o blowing my motor was 10psi. I did run, for a short period of time, 17psi racing a cobra a couple times. extended period was against the GST (SilverGST) 10psi+creep (roughly 14-17psi) and melted the two middle pistons, warped the crank, and managed to drive the car home.

@ 5psi I walked swaped crx's and hatches.
@ 7psi I walked slightly modded Mustang GT's, RSX Type-S' and GST's
@10psi I had roughly 190whp
Since a swap costs more then what I plan to do, and I _already_ have the motor... why waste the money?
Why not just spend a grand on a turbo setup like I did with my car, and build it smart. IE Hondata and injectors.
You'd be surprised what SOHC's can put down to the ground.

Prolly. But I want to cut the crank, and rods to see how long they hold up under boost. =)
Call it an expierement.
My machine shop says they use aftermarket rod bearings, and shaved cranks for Honda's ALL the time.
Everyone on here, and Collin, and alot of others say you can't use them.
I wanna see for myself.
After I blow that SOHC I'll get a DOHC and do shit slowly.

If you want to spin rod bearings, use aftermarket bearings and shave the crank. If your machine shop told you to do that stop using them as they don't know what they are talking about.

They say they haven't spun any rod bearings.
I guess as long as you have the correct sizes IE colours. It doesn't matter?
Like I said... guess.
I want to know why they sell them if they don't work. There HAS to be a reason, and I will figure it out.
I'm skipping the turbo setup, and doing straight motor. Im really interested in seeing why everyone spins rod bearings w/ AM bearings.

Cronic are you saying you need only 5 psi to walk a swapped CRX or Civic hatch but need 7 psi to beat a GT and RSX? Please clarify.
