D14A3/A4 versus D14A8

[hondamake]

Finally got my Civic back on track! D16 block with D14 head runs absolutely fine and passed it's DVLA emmissions test without a cat. Story of my life, always short on pussy. Found a good strut brace but got let down on the Rover IM, the hunt goes on. In my LPG thread I've mentioned fitting a sequential direct injection gas system. This would give the option of throttle bodies or forced induction as the project comes along. Anybody with any info on ITB's?

That would be a great project! Let's continue here!

Dirty mind

Good to here everything rolls well.

Still trying to find the time to finish my D14 motor, 99% complete Hot news I've just acquired a low mileage D13B2 complete engine - 75 x 76 should rev freely. Even better if I can find 76mm pistons, should give a perfectly square 1380cc . Anybody know if it's possible?

Honda gives OEM pistons for rebuilding 3 options: standard size, 0.25mm and 0.50 bigger diameter pistons.
So why not if you put 75.5 mm piston will be close to 76mm

am I correct in saying a3/4 is the 16v version with the A8 being the 8v? that would probably explain why the A8 engine was struggling to make it past 105

Also d14a8 is with 16valves. I am quite sure that all 4-cylinder Honda engines from 1992 until today are with 16valves.
Reason for less power from a8 maybe is the ecu and camshaft

[hondamake]

There are some 8V engines for applications such as the Jazz and Logo but as far as I am aware all more recent Civics are 16V. Somebody has offered me a 1992 CRX with a DOHC D engine that is in solid condition. He wants £1500, I'm very tempted.

Yes you are right.
I completely forgot the 8-valves i-DSI engines from the previous Jazz!

not the i dsi ones was looking on ebay earlier and saw a few a8 engines looked identical to the a3/4 ones. Noticed it stating 8v which would make sense on the lack of power, but then again wouldn't put it past the cam & ecu map being different
