Hello all. I've been on hiatus from working on cars for a while now, but I'm itching to tinker a bit, and I've decided to try my luck with forced induction.
The goal:

-Rebuild new bottom end for FI.
-Keep it simple, keep it reliable. Driveablity is key.
-Try not to cut corners, while keeping it budget minded.
-Low/High boost setup, 230-240 low boost, 300-310 high boost (Update 01/09/12 - Since I've purchased forged rods, I would like to shoot for 370-380whp @ high boost but keep the low boost around 250whp. I might like to hit 400whp on the dyno if the motor feels good enough)
-Possibly run E85 (Update 01/09/12 - Ruled this out due to lack of availability outside of SC)

The clay:

-2000 Accord Coupe
-OBD1 conversion tuned with eCtune
-A couple F23 long blocks with a plethora of Prelude/GSR/H22 parts

Tentative plan:

-Off the shelf pistons @ 86.5mm (forged internals are a f***in' rip-off for this engine) (Update 01/09/12 - Went with Wiseco K568M865 forged pistons for K20)
-ACL main/rod bearings and thrust washers, all new OEM oil pump, water pump, belts, etc. (Update 01/09/12 - Strongly considering against using the ACL bearings due to better sizing availability from OEM bearings)
-ARP head/main bolts from H23 (Update 01/09/12 - Strongly considering against using ARP main bolts due to necessity of align honing and again, likely won't have correct clearances with the ACL bearings)
-Use the crank and rods of the best condition from the blocks I already have. (Update 01/09/12 - Using previous stock block and crank that I ran in the car for 40k+ miles. Pulled this block due to worn rings burning oil, but no other issues)
-Use stock F23 head, IM/TB to retain reliability and cruise. (Update 01/09/12 - Likely going to send stock TB to Maxbore and have local shop port match plenum)
-T3/T04 60 trim turbo

Parts List: continuously updated

Obviously there are a few people with turbo builds on this site, that can hopefully help you out with this very promising project.

Looking forward to seeing the progression.

Were you upgrading your stock rad as well, or is that already done?

Nope, kept it around to beat on every now and then. I replaced every bushing, endlink and ball joint in the suspension a couple months ago and it was riding soo smoothly and quiet. I think that's what made me want to 'fix' everything else.

Lookin forward to the build. Take lots o' pics ;)

I'm going to try to take plenty of photos once everything gets started. I have a waterproof camera that I think I'll keep in the garage so I can just wash it off if it gets dirty. :)


Sounds good dude, this is what i will want to do with my turbo setup in the future.

Haven't settled on the CP pistons yet. As far as I know, they're only available from Raceeng.com for $597

I'll definitely be shooting some texts your way if I get in a bind. ;)

Thanks. I'll try to keep you guys up to speed on what I've accomplished as this gets put together.

I'm sure I'll have plenty of questions for you!

I pulled the radiator last night. It's had some gunk in it for a while now, so I don't think I'll be reusing it. I'd like to replace it with a half-size aluminum rad, but that mostly depends on how much that costs. I'm not really interested in the bling factor.

I don't expect this build to be anything innovative or particularly special. I just want to do things right, document it thoroughly and clearly, and not have to redo any mistakes later on.

With the old saying, you have cheap, fast, and reliable. Pick two. I'm picking fast and reliable, but with a few limitations. The block I'm assembling will have all new parts with the exception of crank, rods, sleeves, and maybe oil pan. Sensors, pumps, belts, and all small components will be new OEM Honda. I've already spent around $360 at Majestic Honda for new gaskets, bolts and seals, and expect that to grow to around $800.

For the sake of reliability I am using forged pistons, but for my modest power goals and sheer cost, I'm not considering forged F23 rods at this point. I don't mind spending small chunks of money here and there to address the details, but I have a hard time justifying $1400 for just rods and pistons. For a while I had considered buying an F22a non-VTEC long block since the cost of the block plus forged rods and pistons would be less than the F23 rods and pistons. I would even buy a new OBD1 engine harness to make everything plug and play, but I'm pressing on with the F23 because I already have two mostly-complete F23 long blocks and close to $1000 in Bisimoto parts for the head. I haven't yet decided exactly which pistons I'm going to use. I've contemplated Wiseco K20 9:1 pistons, Wiseco K20 flat top pistons, K20a3 forged rods, stock F23 rods, and every combination of those. I'm close to just saying screw it and just get the CP pistons, even though I prefer Wiseco's oiling design, coated skirts and cheaper price. :(
