All Motor Mike's - H23A Blue top PDE “Type R” clone build,...
So some people are gonna see the title and think I’m a uneducated ricer kid, but let me start with clarification on what I mean by H23A “Type R” clone. I will be using a number of H22A7(True Type R H series) parts along with various other rare OEM H parts that are “better” then the common ones in some way or another to build a very aggressive (by street OEM parts standards of course) H23A PDE without removing the head at all, only bolt ons and likely Type R/Euro R cams.
This engine will be for a 1993 Prelude S with beautiful rather hard to come by in good condition Type C Midnight blue interior, dash and all in near mint condition no rips at all. This car is pretty cool and I was sold on the fact that it had a full bolt ons F22A1 that was every bit as fast as h23a1 cars I had in the past.
Now seeing as these days I am not making this my race car, my race car being a Twin engine 1995 Subaru Impreza with a EG33D H6 SVX engine w/3.90 trans in the front and a H23A blue top P13 VTEC JDM Accord engine w/P2T4 lsd trans in the back, I’ll be trying to make a street car that makes me as content as my typical race cars do. My last daily being a SN95 New Edge with a 5.4l PI v8 running on a Predator 5000 Positive control induction fuel system no FI or true carb, as PCIs are different then carburetors and FI despite being commonly called “carburetors”. It made far more hp then then the 5.4l was rated for stock on the dyno and I’ve considered running the H23A on a PCI but for the sake of an “OEM” style build I’ve scrapped the idea of running a Predator 5000 on the Honda. But it got mediocre gas mileage at times, great at others, despite me tuning with a wide band so I sold it recently because 10mpg sometimes and 50mpg with the fast cruise fuel shut off averages out to only 23mpg real world from my tests and I drive 80 miles a day some times so that didn’t cut it for me. I believe I can pull 30+mpg with this new build to be realistic.
With that said here’s the build list of parts, the goal is 217+whp, the number claimed by the Euro R/Type S on paper. 30mpg minimum is what I hope for when daily driving out of vtec shifting at 3200RPMish.
2000 H23A SIR PDE engine, 100+K miles on it
H22A7(Type R) Exhaust manifold
PCBX intake manifold with functional IABs
H22A7(Type R) cams from the UK
H22A7(Type R) U2Q7 LSD Transmission
JDM Type S exhaust slightly modded to fit a 1993 BA8 Prelude S
The only non OEM H/F series Honda parts being a P28 that will be Dyno tuned on 450cc injectors, and a lengthened custom 2.5” outlet down pipe for the H22A7 Header as the stock A7 down pipe is too short.
I’m at 5000ft above sea level so E85 may be implemented as well as bigger injectors if needed aka if the goal is not hit, e85 is super common around me so it’s easily viable.
The engine was ordered as a 40-60k miles engine and was had for a good deal price wise but after disassembly I’ve noticed carbon/sledge build up and wear average of a 150-200k miles engine. So I know I’m working with a sub par setup to begin with, leaving my goal in the pipe dream range at best, but regardless I’ve planned this build for months before knowing the condition of the engine so I must continue despite the bad odds. Here are a few pics for starters, I’ll post more as the build progresses, still need a few things and need to give the engine an intense cleaning inside and out. Cleaned the inside of the cylinder head a bit and forgot to take pics but everything from here on will be documented to see if the 217hp claim of Honda’s best stock H engines are realistic. I know the H23A is rated at less then 217hp factory but it’s also only found in automatic cars with a mild tune and a poorly built exhaust manifold/exhaust system as a whole so I am confident it will pick up some power just from better tune, flow, gearing and more carful assembly.
So let’s begin, the H23A after mild cleaning and a few parts for it:

Seems like it'll be a pretty sweet, simple build. Can't wait for updates. Also, if you were trying to put up pictures...they're not showing.
