    Ignition timing help

    Thanks for the reply. All I can see on the ATR flywheel with the timing light is this big plus. (pic of a Prledue flywheel) I take it this means I need to still advance it more to see the 15 BTDC mark? We advance the timing loads and the big plus came in to view. My mates timing must have...

    Ignition timing help

    HI all I am after a bit of advice. I have attempted to do the ignition timing on a friends Prelude which has a H22a7 flywheel. Could someone tell me what the timing is for the H22a7? I am ***uming it is 15 BTDC +/- 2 same as other H22's. Also what markers are on the H22a7 flywheel? Does the big...

    H22a7 power after a tune?

    Oh for sure im going to use the H23 manual tensioner, one of the many little jobs that will be done while its being prepared (thermal gaskets, baffeled sump etc.....) I think its that particualr dyno that is making me only show 155whp, it did the same for my H22a8 Prelude.

    H22a7 power after a tune?

    The reason I got it so cheap was that it has suspected auto tensioner failure. I know that it could spell death or an expensive to fix, but Im hoping that all it requires is a new timing belt and auto tensioner. The previous owner said that the engine would not turn over. Im hopefull as the...

    H22a7 power after a tune?

    Hi all, my H22a7 turned up the other day. It only cost me £360. The a2 only has 183bhp from the factory, there is no way I could get 30 more bhp from the a2 from only spending £360. Upgrading to the a7 (or at least using parts of it) will give me a better platform to get more power in the...

    H22a7 power after a tune?

    The rationale im going on is that if I can make 17bhp off those mods and a "one size fits all" ECU*, I should make at least the same gains (hopefully more) off the a7 with those mods and a proper tune. *The ECU is actually meant for JDM engines, but im using it on a UK lower compression engine...

    H22a7 power after a tune?

    luvmyaccord - How much power are you getting from your mods at the moment before your tune? TBH I would be quite dissapointed with an additional 10bhp only, are you sure thats the right ball park figure?. The H22a7 is to go in my 4th gen Prelude track car which at the moment has an H22a2 in it...

    H22a7 power after a tune?

    Hi all. Any one have a rough estimate of how much power will the H22a7 can make off a tune (crome P28 ECU) with a Fujitsubo manifold, 2.5" decat, and 2.5" exhaust? Are there any examples on the forum of anyone who has previously gone down this route? Cheers.

    Just changed the transmission fluid

    Yeah a gearbox fluid change is a great thing to do as its one of the most neglected things. I use Amsoil Syntetic MTF.
