Lux or Rocky petrol engine? Which way to go?

Post by **elgordomuygrande** » Thu Nov 04, 2004 6:31 am

He guys. Found a complete 3y lump out of a rocky in the ads for a reasonable price . I first wanted to transplant a 18r in my 1.6l f20 but since these are hard to find over here this might be an alternative. I think just swapping bellhousings would be sufficient. Only not sure whether I keep lookin for a 18r or get the 3y. Do they both share the infamous toyo reliability or is one preferred above the other?. From memory it seems that they have almost the same power output. So which one to choose?

Cheers,
Ron

18RGE(U)

I would go an 18RG over an 18R, I used to have a '76 Celica, and with 18RG stock killed the fully worked 18R... Plus the 18RGE has EFI.

Would love to do this this to my Feroza and piss the stock little 1.6L off...
Good luck in your quest.

I have a '94 Feroza... Doubt it would be an easy job.. Would be easier than a V6 out of a commo though but not as nice a result.. hehehe

Upgrade your current engine to Detomaso specs and you'll get 92kW.

what's that involve Murcod?

Upgrade to an engine that will give you the most (easy bolt on) options when it comes to gearbox and transfer cases

Camshaft, extractors, EFI controlled ignition (ie. better EFI system), and larger throttle (IIRC). Would like to do that sort of thing myself if I had the spare $$$. No problems with engineering.

All depends how much you want to spend. Yes, a different engine, gearbox, tranfer case and front/ rear diffs would be ideal- but you might as well buy a different 4WD if you're going to that extreme IMHO.

I just need a decent increase in power and torque, just to compensate for 33's and highway trips to get to the trails, nothing wild, so availability of aftermarket stuff isn't important. Also had the idea of putting a feroza donk in it with the gearbox and tranny, and bolt the output to the f20 driveline. Then I 'only' have to mate both transfers, which would give me a crawl ratio of 1:85. and hey, Then I've also got a PTO!!!. Just my imagination running wild... Guess the easiest way is an 3y swap with the rocky bellhousing and keep the driveline stock. Second in line is the 18R (or twincam) with bellhouse modifications, but availability of these donks isn't very good. So if there's nothing really bad about the 3y's mayby got to go for that option. This weekend I'm checkin' up on the 3y.

Cheers,

How much of a power increase will a 3Y give you? I didn't think they were all that good- power wise I mean?

Post by **elgordomuygrande** » Thu Nov 04, 2004 6:58 pm

The mighty 12r which is under the bonnet right now, isn't really a powerhouse with its 67 bhp and 112 Nm, so there's not much needed for an improvement. Think the 3y takes it to 80 some bhp and about 175 Nm ??

Murcod,

how about bolting on a supercharger... run it at about 3psi.. 6psi max..

That would have to be the cheapest bolt on power I would have thought..
Low pressure, should mean that the engine shoudl handle it without much touching up..

How about fitting a 22RE 2.4 litre petrol?
I'm considering fitting that as a cheaper alternative in the near future as compared to droping a 3.5 rover v8..

Post by **elgordomuygrande** » Thu Nov 04, 2004 10:39 pm

18r(g) or 22R will both match I think, but they have the same problem that I have to fiddle with the bellhousings, which I've never done before so not sure what problems to encounter. tx4000 pointed out that dellows makes a bell kit for the 18r. Thing is, I have to ship it over here which will add to the total bill. Installation of y series will be the easiest way, I reckon. Only don't know how they compare to 18r/22r.

Zilla, you're sporting an 3y isn't it? what are your experiences/opinions having in mind that my f20 has low gearing (4.777 diff and 1.3 transfer high range)and weighs about 1200 kg's??

I know from the landcruiser 70's ( I believe they're bundera's over there) that the 22r lumps are bulletproof.

You'd really have to upgrade your EFI system to do it properly. The torque increase could cause gearbox problems going by other people's experience.

So I take it there are no alternative engines that can easily be adapted to replace the stock knocker... As for wear on gearbox and diff.. That should really only be if you push it too hard.. I'm not planning on doing wheelies or anything..

Just want that little bit extra oomph.. Say for towing the trailer with my bikes on the back, for those hills, overtaking, and just picking up speed with a bit more ease... I really have no idea if my engine is lacking abit of power compared to what it would run like new either... I could go the exhaust avenue, but I doubt it is really going to give me much of a gain...

Murcod.. You thoughts? I've got the stock heads still.. And she guzzles.. I am lucky to get 400k's from a tank I recon.. I did 550K's last weekend, on a tank + $20 worth... And she's sitting on the E now. (Full tank only gets met 3/4 on the guage).

I think this would be the end to it all solution to gain more power.
http://forums.vwvortex.com/zerothread?id=450937&page=1

My opinion of the 3Y.....
Personally i think it lacks the power period. But then again i cant blame the engine as it's hauling a heavy 1.8tonne body and 31inch mud tyres.
Well on the road it seems reasonable as i manged to top out my Rocky at 145kph at 4000rpm and timed with a chronograph. Dynoed at 90hp on the wheels.
But it is offroading i find that it lacks the low end torque.
But mine has abit of work done on it with full extractors, fully blueprinted and balanced, reprofiled cams and a Weber DCNF40.

But I think on a little F20 it would be pretty sufficient.
Oh btw since u're an F20 owner i was hopping if u know the final drive ratios from the F10 to F60? I'm dying to figure out how to source a set of 4.8 final drives for my Rocky. I find it so undergeared when offroading.

From where i am, Malaysia the Bunderas are know as Land Cruiser II SWB. I'm hoping to pick one up as alot of this silly buggers throw their engines for a Supra 1JZ 2.5litre turbo.

Well, just my thought about the 3y, powerwise it'll be ok in the f20. Otherwise it seems that a lil' hairdryer will do the trick.......

As for the diff gear ratio's, the following comes from the workshop manual

F10 1:5.571
f20/f25 1:4.777
f50/f55 1:3.545
f60/f65 1:3.363

F10 transfer case has a ratio of 1:1.383 instead of 1:1.300 in high range
