    I have a 1996 prelude with h23 and P14/A13 ECU. When trying to start it, it fires up for about 2-3 seconds then stalls. I replaced cps, main relay and ecu. And still does the same thing. Can anyone help me?

I'm currently running a f22a but it's dying out so I'm looking to swap to something with some more power but will be good for a street road with a lot of turns. I was looking at the jdm h22 but most of...

    I've had this thing for a few weeks now. It's a 2010 C350 Sport. Unfortunately it was time for something more reliable and in better condition. Last October the balance shaft seal blew out on my Prelude at highway speed. It emptied all the oil within seconds and destroyed my cylinder...

    I'm looking to swap an H23 VTEC into my 5th gen lude and want to put in some stage 1 or stage 2 cams in it at the same time. I know the heads on the H22 and the H23 VTEC are the same, I'm just unsure of the clearances. I know the H23 has a larger displacement due to a longer stroke. Does this...

    I just wanna start off by saying hello and apologizing in advance, I'm somewhat new to the car scene so I might be asking some dumb questions.
