Hey guys.

 

The old 3k let go a while back in my trusty ke30, so I finally got around to buying a 4k the other day.

Ripped the old unit out, bolted transmission etc up to the 4k, no problem.

Dropped into engine bay, bolted it all up - then realised:

 

- water pump is different.

- heater hoses are different

[3k had a small hard pipe on back of head and one outlet on water pump from memory. 4k seems to have both on pump??]

 

Water pump is in need of changing anyway as it is, so not a big dram.

I was just wondering if someone could give me a run down as to what else may be/is different between the 2 motors I should be aware of and need to change/source.

Also, if you could clarify these heater lines/hoses dilemma and how best to hook them up.

 

Thanks

Anyone?

Does the 4k head have a blanking plate where the water-pipe went on the 3k?

If so then simplest solution is to bolt the 3k pump and pipe onto the 4k.

 

Also, if your using the 3k intake manifold check that your ports match with the 4k head (if they don't then your 3k head might be worth a dolar or 2)

 

Only other major difference I can think of is that some of the 4k's have a 4-2-1 exhaust manifold, but this is interchangeable.

Hey mate, cheers.

 

Yup, 4k has the blanking plate on the back of the head.

Since you've said I'm able to swap them and that'll work I'll get onto that this weekend.

I take it the 3k water pump is a direct bolt on too which is good news.

 

4k engine came with manifold setup already attached, So i've just bolted up my front pipe to it and that's all sweet.

 

Thanks again.
