VTEC conversion

[preLUDE S eye]

What would i have to do to make my h23 a vtec? also, Where can i find some aftermarket cams?

[TeriyakiBroccoli]

That is a CLEAN prelude.

[ChrisCantSkate]

well... your 2 options are swapping the head, or swapping the eninge. both will cost about the same, and hoestly yhe h22 will hold out better. once you get the h22, crower has great cams for h22's

there is a h23 vtec in japan. osakamotorsports sells it, or what was the link chris gave me last night

[ChrisCantSkate]

hrm... i just saw that, i dont know anything about tht engine, and have neer herd of it before, it might be a type-o. he is talking about a head swap i believe

[ebpda9]

no, no i actually heard of the h23 vtec, and it's the stock engine on accord orthia the awd wagon.

[cantdrive55]

Yes, the H23 VTEC cam in an Accord Wagon in Japan. It was rated at 197hp and something like 167 ft pounds of torque. No one that I know of has actually swapped it in...maybe I'll be the first in a few years. ;)

[ebpda9]

not a big difference from the h22. less hp and more tq

[ChrisCantSkate]

actualy its same hp, more tq. ryan... i know where u can get that engine for about 2g's if your interested.... if my motor blows, i'll probobly go with it too.

yeah but i think it's an obd2 ecu. i wonder if the h22 ecu will work

id say 999999.9% chance it would. any obd1 dohc ecu i belive plugs into my socket, so i'd use my wiring harness on that engine, like a obd2->1 swap. and jsut keep my ecu.

[ebpda9]

that would be an idea. do they have the same redline and maps thou ?

[ChrisCantSkate]

funny this is up now, ive been reading about a s2k crank going into a h22 giving it a borexstroke ratio almost identical to a type-r, if not exactly. that would mean much higher safe redline. h20 sounds nice. i'd IMAGINE the h23 has a lower redline, but i'll check.............checking............nothing oh well, the search will continue

from what i read before the f20c is a destroked h22 with f1 pistons in it (the ones without skirts)

im assuming the f20c is s2k... the heads are very different, and the......timing chain.... drawing board time....wait crank pully, ok. the s2k engine spins the other way, and the rods probobly need to be custom made to align TDC right, but i get a 2091cc displacment from what ive read, and i can basicaly go with any f or h serise piston.
