Hey i have a question. I want to swap my h23a for a f23 i think it comes out of an accord and is vtec anyone out there can help me with what all i need to do to complete this swap?

AHHVTEC · 08-01-2008, 03:57 PM

its a easy swap but why do you want to down grade

DESPAIN · 08-01-2008, 05:21 PM

Well i thiught i could get more power out of a f23 vtec. What would be a good way to make mine a vtec? I already have intake;exhaust;and headers. Next week i am going to put in a spoon chip and new shocks with a tokico hp shocks & springs kit. Maybe i should just put cams and a turbo?

AHHVTEC · 08-01-2008, 05:22 PM

is the h23 blown up ?

DESPAIN · 08-01-2008, 05:28 PM

No i need to get a valve seet fixed but thats all thats wrong with the motor. I just want more horse power....... At least 350-400hp would be great

AHHVTEC · 08-01-2008, 05:30 PM

well i was gonna say put a h22a head on it but to get that much power your gonna need a complete rebuild and a turbo

DESPAIN · 08-01-2008, 05:32 PM

That was my first plan i guess i should just stick with it. Is the 2.3 better for mo0re power because it is bigger? And if i put a h22 vtec head on there why wouldnt that give me more power isnt vtec better than non vtec?

AHHVTEC · 08-01-2008, 05:33 PM

yea but it really doesnt matter in my opinion once you go turbo. and your gona need it to get those numbers

DESPAIN · 08-01-2008, 05:38 PM

Well all i need to do is put cam gears and a cam and a nice turbo on there and i should be close to that but eventually i want to put new pistons biger throttle body and crome intake manifold.
I think it would be fast enough then!!!!!! But one more question:
Ok, i have stock shocks now and 17" konig rims with i think 205 or 215's tires the new shocks i am going to put on will drop my car 1 1/2 inches do you think my tires will rub?

AHHVTEC · 08-01-2008, 05:43 PM

naa it shouldnt rub, but you will blow that motor up before you got to those numbers on a stock bottom end, you might get 300 if your lucky

DESPAIN · 08-01-2008, 05:45 PM

Bottom end? You8 mean my crank? How much is that going to cost?

AHHVTEC · 08-01-2008, 05:47 PM

i mean everything new pistons re sleved block and all, the crank will be ok prolly

DESPAIN · 08-01-2008, 05:57 PM

Oh ok...... That will be all done at the same, i only want to have to pull the moter once. I do all the work my self. Or at least so far i have, i will do the cams and cam gears myself with a little help from a buddy but pistons and sleeves and head work ie: Valve seats and mabe getting the head milled down will all have to be done at a shop.
