appropriately set-up 202's can rev with the best of them. Remember Toranas with XU1 option ran at Bathurst using 5000-7000 rpm for 500 miles.

You are not building a race engine, but one for a Land Rover. An engine that will comfortably cruise at 4000-4500 rpm and still retain good low speed performance. Improve the breathing a little, and a few durability/relaibility mods and away you go.

Hi Diana,

Yes the 'NEW' Holdon engine....ha ha. A wee small spelling mistake. Early in the morning......now that reminds me of a Rugby song.....as I was returning from a night shift. Did spot it after posting but hey ho too late.

Some interesting responses.

I have not tried the engine out 'up the road' but was just interesting to see what the forum would suggest. Looking on good old Ebay:)...hmmm sorry Fleabay. I see several different complete engines with looms, computers etc.

unfortunetaly not knowing the engine history here I am viewing blind.

How would one of those great 6.0 litres V8's look in one. I know it is not a great engine for the rest of the drive train but you dont have to drive them at full throttle from the off or even when moving.

Just musing:D

A holden six that rev's with good low speed performance. I'd like to see that.;) I personaly don't like them in the Rovers at all but have converted many over the past and the 173 and 186 have proven the most durable out of the box with out mods.

Unfortunately, like our mate Ron, the typos jump off the page at me.

Over a long period of observation and ownership of Holden converted Series Land Rovers, I have not been convinced that the 202 is a better engine than the 186-S. The only noticable difference is that the 202 uses more fuel and requires a manual or purpose ground camshaft to perform as well as the 186 in the Land Rover. A big problem is the reduced coolant capacity and subsequently higher temperatures experienced in the 202. Overheating is by far the biggest problem of Holden engined Land Rovers, followed by oil stavation on steep decents and climbs.

I'm sure that I will be corrected on this, however, weren't the GTR XU-1 Toranas a 186 engine rather than the 202? Holden Torana GTR XU-1 File

LC's were 186 (3100X prefix). LJ's were 202 (JP? prefix, I could be wrong with that). As I said, there are modifications required to convert a low speed high torque family car and light commercial engine to a different application. Larger sump and baffles cure the oil supply problem on slopes, high volume oil pump, engine oil cooler, cross drilled and relieved crank to improve lubrication of big ends and piston pins and provide extra oil cooling of pistons, better pistons, Starfire rods ( used in XU1's, Starfire 4cyl. and the blue 12 port engine). If you are getting serious about your engine building get a fully counter-balanced crank from the blue 12 port engine and have a competent crankshaft shop modify it to fit the red engine. Cooling was never a problem in Holdens or Toranas. Probably the LR needs a bigger radiator to cool the additional horses.

Thanks Brian

I do remember the first of the racing XU-1's because I was at high school at the time and was sure I remembered that they were 186's.

I hadn't heard about all the other mods, so that is good info. Regarding the oil starvation, I do remember for Land Rovers we always tried to find the sumps off the Holden HT because the bulge was in the middle instead of at either end. Then we usually fitted an oil cooler to supplement the oil volume as much as cool it down.

My!

This post has opened a can of information.

An amazing font of knowledge on the Holden...or is that Holdon!!!

What about the larger engines and the good auld Ford?

Any other engines....of the modern kind?

Chilly

If you fit a modern engine you also have to fit the associated pollution control gear that came along with it.

People have fitted the V6 alloy engines but these days you also have to make your own adapter kit and the cost of that is often worth more than the vehicle you are modifying.
