Holden Conversion.

Can a Holden 6 that is currently bolted to a Series 2 (not 2A) gearbox be transfered to a Series 3 gearbox without changing the adaptor plate?

Yes - provided that you have both 2 1/4 litre gearbox bellhousings. Or a 2 litre 4 cyl in the S2 and 2.6 litre 6 cyl in the S3.

There are two bell housing patterns used in Series Landrovers - one is common (with minor variants) to the 1.6, 2 and 2.6 IOE engines (and I think the V8?), the other to the 2.25 petrol and diesel. Doesn't matter what Series it is,, just the engine type. Where you can have a problem is if the Series 2 is a 2.25 and the Series 3 is a six originally. Note that the Series 3 and the Series 1/2/2a have different actual bell housings to suit the different clutch mechanism, although this does not affect the engine adaptor.

And, if it is not one of the hot rod Holden sixes, she will be slow.

The 186S can rev, but the rest of the stock Holden sixes, only rev to about 3,300 or 3,500 RPM.
Compare that to the Landy at 4,250 RPM and you get a slow vehicle.:(
You will lose 20 to 25 percent of top speed. They do have the power and torque that the little 4 doesn't though.
I have only been in one hot rod Holden powered Landy.
Very frightening, for a short wheel base S2, to be able to pull over ninety miles per hour in third gear.

Or impressive.:D

Do it it's cheaper than a Landy engine rebuild.

Just wondering does the 253 red motor fit on the red motor adapter.

G'day All, The 253 being a small block V8 will not fit the 6cyl adaptor plate, end of story cheers Dennis:wasntme:

Hi all - In the dim dark ages I had an adapter made to suit the Holden 253 V8 to the Land Rover gearbox. I also needed to swap the diffs for the Rover car 4.3 ratio type.

The big problem I encountered was that in my original 6 cyl chassis the width of the V8 block was too wide for the recess in the firewall. You need to widen the recess a couple of inches. The next problem is the rear spark plugs need to be accessed from within the cab through holes in the firewall, these need rubber gromets.

If you want more grunt why not consider a 6 cyl 269 Chev. These were fitted to some of the Bedford trucks and Chev pickups. They look like a Holden red engine on steriods with taller side plates.

Either that or a Ford Falcon 250 6cyl.

A friend had a SIII or IIA with a Valiant 265 engine.

G'day All, I think you missed the point Diana,, he asked will the red 253 engine fit the holden adaptor plate the answer in the short term is NO!!. I have made adaptor plates for 6cyl holden, ford 302 V8 and Diahatsu diesel to fit series Land Rovers, so I suppose maybe with some real ingenuity and a bloody good wksp you might be able to make anything fit anything, cheers Dennis:wasntme:

[Michael Elite]

yeh ill just go the 186 red motor easier

[LandyAndy]

302 Cleveland goes in EASY PEASY,but you have to modify the front xmember and put a cut out in the chassis rail for remote oil filter oil line connections.
With the extra weight up front she handles real well,most impresed!!!
Windsor with the tighter V would even be better,no need to change the plugs on the left bank via the mudgaurd!!!!
Got one in the shed Ive done from scratch,AND YOU NEED TO GO AUTO TOO!!!!! If you want to keep a gearbox behind it. Tough 351 was the plan,gone pretty stale at the moment.

Proberly easier just to put the 186 in.

[lro11]

I found that the 186 would run out of fuel on a steep hill and water crossings were a problem because the electrics are low on the engine. Only my two cents worth.

[Michael Elite]

When you do the 186 conversion can you use the stock clutch and flywheel and pressure plate and starter motor or do you have to youse a different one.

No I didn't miss the point - you had already answered the part of the question about using the Red (6 cyl) Holden engine adapter. What I was adding was a few more of the difficulties of using the 253 engine and suggesting other options, 1 that (probably) uses the 6cyl Holden adapter and an alternative of essentially the same cubic capacity as the V8.

Cheers

Hi, last weekend Mick(Wannalandy+) and Mick (Blue Bandit) gave me a hand removing the Gear box from Rusty (a 1979 S3 with a 1989 Holden conversion). When we got it out we found that the Spriggot Bush was badly worn and was half out of the rear of the the Crank shaft with small bronze 'filings' in the bottom of the Bell Housing. What Spriggot Bush should be installedva nd where can I get one?:(

Any help would be appreciated, I read the post from P38 rover which was great:D but the link didn't cover this point.:mad:

[Dinty]

G'day All, The 'Spigot' bush for a holden conversion (a long time ago) was a standard Land Rover part or it was back then, the people who manufactured the conv/kits used std Land Rover parts in some cases. The Spigot bush is readily available from all the usual suspects, cheers Dennis:wasntme:

Sorry I missed this question.
There are several options - the early kits then used the Standard Holden clutch pressure plate on a Land Rover friction plate. This gave a very harsh clutch "feel".
In the later conversions modifications were made to the leverage points in the Land Rover pedal with slightly better "feel".
There are 2 other better options - some people manufacture a replacement Holden flywheel drilled to fit a Land Rover clutch pressure plate. The least machining type is where you get the Borg and Beck pressure plate housing from either a Standard Vanguard or Ferguson Te20 tractor (which bolt onto the original Holden studs) and have the contents of a Land Rover 10" Borg and Beck pressure plate fitted in.

All conersions need to put a standard Land Rover spiggot bush in the flywheel.

Hope this helps.

Bobslandies has a windsor 302 in his S2a driving a NewProcess 3400 gearbox mated to a standard transfer. If doing the conversion today he would use the New Venture 4500 a 5 speed update of his current box. You would want to make sure you had Salisbury rear end (or a Ford 9"/Detroit Locker in Bobs case)

Thanks Dinty, and now I can even spell it:wasntme::D:D

[somewere~at~nowere]

just chuck a dirty old holden 202 red engine in and buy a turbo kit for it but may cost $$$$
