Killerolla Posted December 10, 2008 Report Posted December 10, 2008 Ok at the moment i have a civic with a b16a in it. Nice little rocket but ofcourse front wheel drive. What i would like to do is to put the b16a into the ke30 but the problem is that the b16a in east west. If I had the money i would just buy a f20c but I'm not a rich man. Has anyone attempted this or is it just a dumb idea??? Ps: Please to don't say dumb idea. Cause i have the car and the engine. Quote
Trev Posted December 10, 2008 Report Posted December 10, 2008 You will have 4 or 5 reverse gears :D Engine rotates the opposite way. Quote
Killerolla Posted December 10, 2008 Author Report Posted December 10, 2008 But at least reverse will go forwards lol. Is there a way of getting around this like running the diff upside down. I have know idea I'm just hoping it can be done. Quote
Redwarf Posted December 10, 2008 Report Posted December 10, 2008 Finding a gearbox will be your first issue. Quote
Killerolla Posted December 10, 2008 Author Report Posted December 10, 2008 Finding a gearbox will be your first issue. Ive been looking for a f20c gear box but the engine is rwd so i don't think that would make a difference. Could i use the gearbox i have then then just get a better drive shaft and take the other shaft out??? Quote
Redwarf Posted December 10, 2008 Report Posted December 10, 2008 (edited) No. An RWD is a comletely different animal from an FWD box. There's no guarantee the a f20c box would fit either. In fact I'd say that it proabaly can't. Edited December 10, 2008 by Redwarf Quote
machg Posted December 10, 2008 Report Posted December 10, 2008 (edited) Any conversion is possible given enough time and money, oh yeah, you said money was an issue, LOL. Seriously though, get a measuring tape, I reckon you could make/have made up an adapter plate to bolt the engine up to a T50 gearbox, or a custom bellhousing. I don't know if the T50 would like being spun backwards. If the input to the diff is fairly central in its location, I can't see why you couldn't turn the diff upside down (obviously involves removing, relocating and re-welding all the diff mounts) to sort out the engine rotation problem. Then there could be engine packaging restrictions (ala 20V to rwd) and oil surge problems. If you had access to the right tools and shit loads of time, I wouldn't say it was "impossible" but certainly wouldn't be "easy". Oh, yeah didn't Honda change its engines to rotate "normally" a few years ago, (i.e. after B16As, but before 2006) with the hope of selling some of its technology to other engine manufacturers?

The F20C (S2000) engine runs clockwise like a normal engine does so it is an easier option. I think if you turn the whole differential upside down (not just the centre) it should be O.K., don't all brand new Honda engines run clockwise, not just F20Cs?

No cause you are spinning the input to the diff in the opposite direction. Dunno but the s2000 already has a gearbox mated to it thats why it's easier. Quote
towe001 Posted December 10, 2008 Report Posted December 10, 2008 If i'm wrong correct me From a quick search i did the F20C spins the "correct" way where as if its a fwd/awd honda the motor spins "backwards". Quote
curly Posted December 11, 2008 Report Posted December 11, 2008 if you flip the diff the pinion bearings will not be running in oil, you could run pump and squirters but the the pinion and housing will be to close to the floor, why not reverse the rotation of the motor only need new billet reverse direction cams, rev direc oil pump, rev rotate starter, seens alot of trouble and very expensive Quote

white_sandshoe Posted December 11, 2008 Report Posted December 11, 2008 Thats not the main issue, The diff back lash will be running on a more square side. I second that... have a look at the crown wheel... the teeth are cut differently on one side... the side they mesh... the side that is being pushed by the pinion. If it's flipped, the pinion will be pushing against the square cut side... it'll whine like a bitch and most likely fill your diff housing with metal shavings reasonably quickly at a guess. I got a good idea though (if you're wanting to throw money around, or feeling quite nuts, or both) jam your cute little FWD engine front to rear, run one custom shaft to the tail, and slap another one into a diff up front to push the front wheels... 4WD FTW!!!
