So i have recently aquired a possible source for some cheap 4 age's and extra rolla related goodies.
The question is would i be silly to pass up the oppurtunity to wack it into my Sierra atm as it stands (in a million bits getting painted) or will it require more cutting/ welding of the floor pan, moving tcase again and getting another gearbox as well.
As far as i can see if everthing went real great would be bar minimum up for
engine 500 (maybe)
Jackshaft lengthed/shortened 100-150
so 600 bucks for best case, but its never that easy.
I assume i cant use a 4k box with a 4age? 700 for a t50?
Will need to fab new engine mounts (not that hard)
Then theres the wireing cost 2 slabs +
Plus new radiator 200+
Wouldnt mind chunking it in, but only really toying with the idea. So if someone chould just tell me its an outright waste of time would help me get ontrack.
Have done a bit of a search but cant find much. also doesnt help that 4k isnt an accepted word in search, must be 3 letters long..

Dont forget efi fuel system, converting 4age cooling set up to RWD (FWD waterpump and plumbing all faces wrong way), converting the intake to RWD (FWD faces wrong way), exhaust manifold or extrators (FWD faces wrong way), converting to hydrolic clutch (T50 is not cable)

But well worth it if you want the power.

Yer i thought there would be something like that i forgot, according to the kiwis worked 4k's can make a few more herbs than a stock 4age, and probly for the price of all the parts i would have to buy to put the 4age in, but i guess if i wantend put you back in your seat power i wouldnt of brought a sierra.
Thanks Stroker.

I've driven an sr20 powered sierra, I was frightened
Too much power is a bad thing, even with its auto.
Though efi etc would be nice.

Yes this is true BUT a K engine making power like that is a very CRANKY engine. High compression, big cam, wild head, twin carbs, rough idle, heaps of revs to get them off the line, over heating unless up in rev range, even getting one to make 100kw you cant drive them smoothly, flat out is ok for a curcuit car or rally car but smooth even power iswhat you want in a 4x4.

You can get the 4K performing really well with mild mods you can match a 1600vit pretty easily, if you go down the track of doing some work on the 4k give me a PM, I have a couple of early big port heads here.

You could always keep an eye out for a 7K, I know they are rare but it will boly in to yours and you get EFI.

Hopefull 12 months time i will be in the postion to start working on the motor abit more than i can afford at the moment, i have a complete second motor under my bench atm, and would consider some port polishing (dont change the shape just remove some casting marks) and a set of extractors and have a very agressive cam but would need a big carbie to run it well. possibly look at a quad carbie set up? 600cc bike carbs sell for a bout 3-400 bucks for a used set off a wreck with a bit of mucking around with manifolds i could have somewhat of an improvement, the car will be mostly for mud and maybe sand (not a big fan of hills nor is there anyaround) so low down power doesnt worry me to much, and considering a flywheel shave, people are saying they can take 2-3 kg out of a stock one, brings it to around the 6kg mark or a titanium unit for 300 bucks is just over 2kg. would make a big difference in 1st and 2nd in the mud i would think. As far as efi goes would like to stay clear of it, if i were to run the 4age i was going to go with a set of dellortos (spelling) he had with the engine, wireing and eletrics is a pet hate of mine an i like to keep things simpleish.

I'd keep an eye out on rollaclub.com and get a 5k, they pop up on there pretty regularly. much cheaper than a 7k, it will bolt straight in if you're already set up for a 4k, and they have HEAPS of torque, they were a 1.6 and came in Toyota vans and forklifts.

[douglasgiersch]

i see a few parts for the 5k's labeled forklift motors, would consider it because easy to get LPG bits for it, cheap car to run then

Hey 2stroker,

Have you ever been in a zook with a 7k in it?

I currently have a 5k (engineered) in my LWB and really want to have an EFI engine. When I compared both engines just by stats off the internet the 4age looks a bit more attractive.

7k on the other hand has more torque and would be a straight bolt in.

Both engines are priced about the same but i reckon 7k would be soo much easier if it had much better gains than the 5k

Thanks

No I have only seen then in photos.
