Hello HT, Its been awhile since I've been on here due to me having an Audi B5 for the past year and a half. Before then I owned a 94 Del Sol Si,94 Civic Coupe,and a 97 Prelude Type Sh. I am proud to say I am the owner of my Second 97 Prelude Type Sh. I bought the car not running with a blown piston. I pretty much bought the car at a horrible time because I just got laid off at my job smh. Anywho, I have a few questions on which is the cheapest route to get this baby running for some time. It seems that the piston in the 3rd cylinder went and doing so it damaged the sleeve in cylinder 3. I recently called Napa and they said for 225 they would; hot tank the block, resleeve cylinder 3, and hone out the other cylinders. If I did that and got some new pistons do you think that'll get me running for a short period of time so I can get around in the meantime? Lmk what your thoughts are on it. Thanks!![/IMG]http://

 

Just be sure your NAPA guys know how to hone your h22's FRM sleeves.

 

Yeah I wouldn't trust any shop that said they could hot tank and hone an H22 for that little, let alone "replace" a sleeve. If they want to replace any sleeves, they are probably thinking iron liner, which would mean all new pistons for iron instead of FRM.

By the time you do all 4 sleeves, 4 new pistons, new bearings, seals, oil and water pumps, timing assembly etc, it would probably be cheaper to buy a JDM engine, replace the pumps and timing components, and drop it in.

 

Agreed, 225 is significantly less than I would expect for a re-sleeve and hone. "Get what you pay for" is the operative phrase in this situation. That said, I'd pick another route.

JDM motors are an option, but require a bit of modification to make them compatible with USDM-spec cars.

You might be better of buying one of these blocks:

They're posted in the For Sale thread at the top of the forum. You have options, it's up to you how far you want to go.

Good luck.

 

If can do most of the work yourself, getting another block may be your best bet to get up and going on the cheap. Keep in mind two things: you have to get a block from an SH or Type-S; you can not use one from a 97+ base model, an H22a1, or H22a (except Type-S), etc. Also note that your 1997 engine uses 50mm mains unlike the 55mm sized mains on all '98+ motors. Given that you're going to need at least one new piston anyway, if you find a 98+ bottom end that includes the crank, rods, and pistons, it will swap in fine.

Another option worth considering if the cylinder walls are in ok shape is to overbore them to 87.25mm and get Mahle Gold's (I noticed some relatively prominent knicks in the photo, but aren't sure how deep they are). You'll want to find a reputable machine shop to do the work (I wouldn't take it to Napa to be honest; call a couple local Honda dealers, ask for their service department, and then ask them where they get their work done); working on the FRM liners is different than iron liners and requires different honing stones and a machine that can run the slower speeds that are spec'd. The big benefits here are a bump in compression and larger valve pockets that will get you set for bigger cams down the road. You should also end up with a bit better P2W all around with better (less) leakdown as FRM cylinders are known to go out of round over time, so the overbore should true them up. This is obviously a more expensive route (~$1k), but definitely better long term.

Obviously, if you're pulling the block, it's a good time to get a couple other things done as well if you can afford it. The first one is to replace all the bearings. If you want to do the balance shaft delete now is the time. Depending on current mileage there's also new oil pump, water pump, manual tensioner & timing belt, and clutch. Also, if you stick with your block or get another '97, an H23 crank with the extra stroke is worth a strong look since they can be had relatively cheap.

I do still have my block available if you're interested (it's the second one Jefe posted) along with the pistons from that motor; PM me if you want to chat.
