I thought they were a much better engine than a 4k?

Has been done, I think it was A J P S that did it.

There was a guy a while back that asked the same thing. Ive turbo'd a fwd 4a-c, and ran a nissan n13 injection setup. It was run on carby for a while, but even with the injection setup it turned out to be a bit of a waste of time. More of a novelty really. I ran 5 or 6 psi, and didnt get a big power gain. Not worth wasting your time or money IMO. Good luck.

being overhead cam and larger displacement, yes..... the only other pro is that when you pull them out, a 4age fits straight back in there.

The K series motor is far easier to work with. Though the power gains aren't as plentiful they offer much education for a beginner.

I had a 4a-c in my third corolla, ae71 spririt, rebuilt it when I first got it and it never ran right. Called around and nobody wanted anything to do with it... which is why I call it, a BASTARD!

cheers guys well the turbo idea is out the window DAMN haha... want a little more boogie though... maybe just full 2" exhaust, extractors, cam(if i can find one) and maybe a bigger carby to suit? My car is bog stock bar some aftermarket shocks and springs just want a little more go.

if your interesting in learning a little.... spend a couple of hundred on a VRS kit. Pull the head off, reseat your valves and port the head yourself. Sounds hard doesn't it. You can also port the intake manifold to suit. I spent $40 on a pnuematic die grinder and $55 on an alloy cutting piece from Trade Tools. Use a manifold gasket as a guide and go for broke.... I did.

 

Buy an adapter plate to suit a 32/36 webber, they're easy to find. The webber will be a bit more expensive unless your lucky....off ebay. Get your extractors and exaust and it'll have poke. You could probably do all of this for less than $1000. It won't beat V8's but when you notice the improvement you'll feel all warm and fuzzy inside.

Hey mate thanks for your input... i would definitely do everything you said on the later part of you reply(exhaust etc), but porting the head and reseating the valves and porting the intake... would probably not feel confident without a bit of on hand advice from someone on the know.
