3k/4k Cross Flow Heads?

[WinKE55]

I asked a member on here last night, and he said that there are these heads out here. But he also said they are rare. I just want to double check and actually get some proof they existed?

 

Are there any 4k or 3k cross flow heads? Does anyone on Rollaclub have any at all?

 

 

Been searching around and seen 3KR's, I am pretty sure they have cross flow heads, but how hard and expensive is the actual 3KR itself? Is there any engine place to buy one etc?

[love ke70]

pretty sure its a 3k-r

 

give up all hopes and dreams of owning one. you never will.

sorry

[WinKE55]

:hmm: Would the head even share the same gasket as a normal 3K or 4K head would?

 

I want one. Or even just the head.

Hi,

Id give up your hopes and dreams. Only cross flow head was 3K-R and if you were keen had a block of billet metal make your own cylinder head.

 

But 3K-R I saw a guy the other week pay $2000 JSUT for the crank out of one unused new as NOS part. TRD actually made a lot of 3k-r shit for KP61 racing cars in japan parts arent to rare BUT cost a lot..lol Also 3K-R crank runs larger bearings and some a flat toothed belt to drive cam/ fuel control etc so it will only fit with a shit load of mods to a stock 3K also.

THEYRE NOT CALLED AND NEVER HAVE BEEN CALLED 3K-Rs </brain explosion>

 

They are called 150Es and no you will never ever find one so stop looking and asking.

[Budowski]

so where does all this 3kr mumbo jumbo come from 1st ive heard of it and i found a link to a pic in seconds once i was told, unless the pic is wrong coz its isnt a 150e ? no offense I'm just all of a sudden curious

[WinKE55]

Do you have somewhere that will tell me about the 150Es then?

 

Yeah.. Same with you Budowski. I have the same thoughts..

What everyone calls a 3K-R is actually a 150E. Its a racing engine and only a handful were ever made beginning around 1973 and ending sometime in the early 1980s when the starlet was replaced.

 

Translation from a japanese magazine:

Based on the Toyota 3K engine of 1166cc, engine was increased to 1293cc. The result? 180ps (hp) @ 9500 rpm. Torque 14.0 kg at 7000rpm. Starlet is fitted with front and rear spoilers, tubular a-arm suspension and a differential oil cooler. Although having a heavy weight of 717kg (about 100kg heavier than Sunny), with its power-to-weight ratio of 3.9kg/PS vs. the Sunny's 4.0kg/PS, the Starlet's perfomance was better.

 

Even if you ever did manage to find one and pay the arm and leg it costs you'd have one hell of a time trying to fit it to a standard block, the camshafts would be seriously nasty (they were designed for oval racing with continuous running up around 10,000rpm) and you'd probably end up killing it because it was never intended for any other application, certainly not road use!

 

 

I'm still curious to know who said I had one Winky....

[Budowski]

ahhhhh i needed that I'm spent, lol i love hearing about these projects toyota comes up with being past and present. pity i have plenty of 3k stuff laying around

[WinKE55]

Irokin, Darren informed me that you had one for sale around 6 months ago. Maybe he was confused with something else? He is a user on here. Pretty common one.

 

Also, another question about heads. The 3k bigport head, the only real difference was that the inlet and exhaust ports were bigger from factory right? Nothing else?

Gotta add again....

 

Ben not actually 150E Toyota names this engine the 137E...

 

Now ALL part in that motor apart from head and fuel setup are normal 3K TRD parts...got pics and part numbers of the lot. BUT the cam has HUGE bearings crank has bigger bearings oil pump removed dry sump installed etc. If you had the cash you can get all those TRD parts and make it and some of those heads still exist BUT the cash you would need your year 12 high school job wont get it for you.

 

Below is a picture of the TRD 3K/3K-R/137E crank...Guy paid $2000 for it and got it shipped here. That is for 1 part don't start on price of the rest. I have seen dizzys, dry sump stuff etc turn up for thee motors but rare...

 

So I wouldn't bother looking for a motor most were made and lots of parts were made but the heads not many were made and most were killed in racing so you know rare. Also TRD pistons have racing rings on them would chew oil on the road and bored so big motor wouldn't get long before it would break.

Yeah big port early ones have smaller valves but...And if your picky a lot of difference in port shape from JDM dished piston motors like 4K/5K compaired ot normal K motor heads.

Yea, best of luck getting one of the trd 3k twincam motors.

 

Some in action.

Ben not actually 150E Toyota names this engine the 137E...

 

Orly? I'd be interested to see some research to back it up. 150E fits with their other 4cyl NA racing engine naming. Perhaps there were two iterations? I'd be interested to find out...

 

 

WinKE55 what I suggest you do is go for a 2T-G (if you want the nostalgia look) and forget about throwing money at a K engine.
