Just wondering if there are any toyota twin cam heads that will fit on a 4KC block? i was thinking maybe a 4AFE might be close.. any ideas?

hang on.. never mind.. i just noticed how dumb that idea was lol

It's been asked before, people postulating whether you can fit 4A series heads onto K engine blocks.

 

Short answer, no.

 

Long answer, anything is possible. If you know anything about Datsun L series motors, you'd probably be interested to learn that OS Giken built a twincam head for the L series.

I worked a bit with a mate who designed and cast up his own head, for an OHC steam engine. There was lots and lots of design work, he made the pattern for it himself etc. After seeing it done first hand I'd prefer to go through that much effort before I bother trying to crossbreed another head onto a K.

 

Your biggest issue I reckon will be getting a timing drive to it; you'll not only need a new head, but complete new timing covers, water pumps etc and all the problems that go with that.

yeah..

 

and i remebered that the cam is in the block and not the head lol

wow that twin cam for the L series is dope as f@$k. 30 000 smackaroos tho

Has been done ,correct me if I'm wrong 151e built by toyota for racing .

 

Think it was 3k base .

 

Expect to sell your first born to buy one .

Replace the whole engine with a 4age.

na id rather just do up the stock engine.. can't really be bothered swapping motor over.. don't really have the time either..

you'll spend alot more time/money on doing up the stock engine rather than a conversion.

 

you should be able to find someone selling all the parts for a 4k>4age conversion

 

only way to be getting good power figures out of a 4k is to turbo anyway.

How is conversion going to be cheaper, just buying the engine and gearbox

would cost more than a rebuild on a K engine. Plus the fact it'll need engineering

for road use.

So far $1600 has done bearings, (mains & bigends) cam cut, twin SUs w ram tubes, airbox/cold air system, head skim & valve cut, & extractors.

 

The only further cost will be to fit a larger exhaust when its all back in, another $150 say.

yeah..

 

and i remebered that the cam is in the block and not the head lol

The T series motor has the cam in the block. But on the twin cam version the cam is replaced with a lay shaft so that the cam can be moved up to the head with its twin

Bull shit. You can get plenty of poke out of an NA 4k, even a 3k screamer...... which would be enough to beat a stock 4age..... for less money!! :jamie:

 

Unless you're doing a dodgy, half arse conversion.

The ultimate versions of both the 2TG and 18RG were made by TRD- they were known as the 151E and 152E respectively and came with 16 valve heads, both were available in carburetor (50mm Mikunis) and fuel injection (mechanical Denso) models. There was also a 150E 16-valve version of the 3K / 4K engines. These 16 valve heads were the forerunners of today's 4AG, 3SG, 7MG, and 2JZG engines. These were race only non-production heads, with heavily modified blocks. The 152E race engine was used for US Toyota's early back-to-back victories in desert/stadium racing and IMSA GTU events. The 152E was used in Europe for the FIA World Rally Cup ser

 

hear mate had a look i hope this helps

Not much point wacking a turbo onto the 4k. The money in the long run is ridiculous. Your better of throwing a 4age in it. You wont regret going 4age thats for sure.
