3K Small Port

[Bamboo]

I've bought yet another 3k. It makes 3 in the collection. I've also got 2 sets of pistons and a set of bearings. My plan is to make a really revvy 3k.

 

My question is..this engine appears to have air pump type injector holes, blanked off with bolts. Numbers suggest a small port head. Does any one know if 3k's came out with air injection to the exhaust manifolds?

Not that I'm saying it's a bad thing, but why do you want to work a 3K/collect 3K's rather than the 5K or 7K route?

Cheap and easy.

 

Also, I like the fact the plate in my car says 3k. I only do standard! 5k and 7k sound good, but I want a square motor, 'cause they love to rev!

Boo,

 

In regards to the "air injection" dads old Toyota Liteace KM20 had the air injection engine - only it was a 4k. With that too, it still had the injectors and air rail attached, but the previous owner disconnected the air pump. I was under the impression air inected motors only came in the commercial vehicles as they were imported from Japan where the emission laws were more stringent.

Those holes are for pollution gear that runs from the exaust ports.... my 5k had the pollution gear when I bought it.

A 3k with all that crap. I was rather taken back when i found my 5k had it. I was thinking that the "K" motors never had the air injection crap. Whats happen with the two speed ?

The two speed is going to be removed, and then I'll attempt to sell it. I can't see a lot of demand for the old toyoglide. Shame really. They guy I bought it off claimed it had only done 76,000ks.

K motors could have air injection on them stock.

 

All flat top piston K heads if you run your finger along the top of the exhaust port they have a hole in them for it cast in. That is why there a crap port design and the first thing you do is port them.

 

BUt some one has taken your injection off and blanked it. No surprise.
