Ke30 manifold swap.

[Jeff in Thailand]

I'm looking to get rid of the stock intake and exhaust manifold on my k3 engine, what would be a good replacement for these? Thanks for any help  and advice.

Have a run through this-

Decide which carbs you want to use and start hunting for a manifold. You'll see I used SUs, popular one is a single downdraught Weber off a small Ford, better would a single side-draught DCOE Weber, but if I was to do it again I'd use bike carbs!

Extractors are pretty much just the 4-1 from Redback or similar. Make sure the heights of the manifold's  ears by the bolts of both inlet and exhaust are the same, use a half-washer if needed, and buy a single-piece gasket.

Why do you need one? Car modding going on? I assume your in Thailand, how's the old Corolla scene up there? Still got parts around?

Just a little modding,replacing the 4 speed with a 5 and want to get a little more out of the k3. Lots of Corollas here in Thailand, and seems to be plenty of parts to.

Ah, so cam grind, head port & skim, extractors and exhaust system, and bike carbs!

I don't know if a PM would reach Tommy-

"Hey guys got the manifold plate cut out and also a few spares"

If he still had a spare manifold plate it would make your life easy!

You can see that a bike carb manifold has stub pipes welded onto it, and the carbs go on with a rubber hose and a clamp.

So, bike carbs or DCOE Weber...

Got the exhaust, can get a weber 32/36 for a good price, having a hard time finding an intake manifold here in Thailand for some reason, I  would like to find a single carb intake. Looking for a reputable engine shop here for a rebuild.

What motorcycle carbs would you suggest?

[altezzaclub]

Whatever you can get hold of in the 750-1000cc range bikes. Suzuki GSXR are most popular, Mikuni carbs. They will be 4 carbs of 36 or 38mm throat, used to running a 1000cc at 15000rpm, so you can think about the outrageous flow. Even a smaller bike will run a 3K easily, a 600-700cc 4cyl.

It was on my list, but I never got around to it, the 4AGE was a much nicer way to go.

I was looking at some 4age motors,not sure of what all the changes I would have to make for it to fit in .
