4ac In Ke70

[ROSSOTOON]

hi,

i am looking at re-powering a ke70 but don't have the funds to put the 4age motor in, was thinking about putting in a warm 4ac what are your opinions on this, and were can i find a good 4ac motor.

cheers ROSSOTOON

i also considered this when i couldnt afford a 4age.

 

ive been in ae86s with 4acs that appear to be quite fast,

 

ive also been in a few that are pretty damn slow......

 

in my oppinion, by now all the 4acs would require some sort of rebuild to get them up to scratch. so either valve guides or new rings etc.

 

i mean if you already have an ae71 pedal box/tailshaft/gearbox/crossmember and the only thing holding you back from 4age is the engine itself (and associated fuel/ecu items etc) then if you can pick up a known good condition 4ac then i say go for it.

 

however if you reckon you can save some cash and 4age it within say the next few months, i would just wait till then.

 

4ac is a good upgrade over the 4kc, but if you can wait a bit longer, then 4age is better than both of them.

Thanks for the reply, 4age would be nice but how do they go for registration in nsw.

just needs to be engineered. you'd have to go through the same deal as if you wanted to put a 4ac in it and get it registered. 1.3lt to 1.6lt.

Or you could power up the 4k. The 4k with (extractors, exhaust, cam, unknown carby) I've got now is faster than the stock 4AC I used to have, sounds better and has more street cred. Kind of.

Anyway I like it enough I'm going 5k and powering that up.

 

EDIT: but if you're planning to go 4AG in the future, doing the 4AC conversion will put all the bits in place as someone said then you can just drop the 4AG in when you get the funds. Plus a 4AC should pretty much come free with all those bits sort of thing.
