Thread: 202/3.3L conversion with varijet carby

I'm not a fan of GMH in Landys Although the 2.6 Six were no good. Since no one has spoken.... what year model is your S111? The commy six aren't a good one to use as you have found out. Start pulling that polution crap off and it will need a retune. The 202 also hate being reved hard on stock gearing. Depends on year model the 186 is the most durable. We have converted a few here and the 202s all burnt holes in pistons or spat small ends They are useless off road.Tony

Put a ford 6 in it if any thing or a hemi 6

Jeez, I hope the 202 in my IIA is OK. I haven't got it going yet. I was thinking of fitting Rangie 3.54 diffs front and back

High ratio HR gear in transfer is best The last 3.54 I put in a 4.7.... Well lets say the housing lost some weight You will find out why. Other drama was Low range was taller and Series boxes don't enjoy a lot of 1st gear work. As is on end of shaft and kills small bearing. Set gearing up so 2nd does hard work and they dont fail as shares load on shaft. Holden have a bad torque curve for this. Mainly 202. Thay are flat then snarly in mid range. 202 don't cope with being run at 4000 RPM under light load.161,173,179,186 are only ones that last out of Reds. Do not spin the tyres. Just my experiences This is why I dont like GMH in Series. Remember.... Go easy on 1st then 2nd give it hell. Tony

My '76 LWB SIII is not going to be used for 'heavy' off road, it has been converted to a camper van, so will do a lot of highway miles, it does have a Fairey Overdrive fitted, also, the gearbox was totally rebuilt some months back now.
It will hit tracks for sure but nothing anything close to crawling speed and/or winching....been there done that

It is my weekender for when I go fly fishing and sleeping under the stars

So the question really still remains, which hose connections are a must have to the Varijet carby, thanks people.

One quick headsup: if your 3.3 was mated to an auto originally, the vacuum advance port in the carb is designed the wrong way round, full advance at idle. I had that problem on the earlier Holden carby on my S3.

They do this because you have taken a low speed high torque passenger car engine and put it into a car with low gearing that requires it to rev for prolonged periods at speeds the manufacturer never intended. Properly modified to its new application you will have no problems. Remember the Torana GTR's with XU1 option pack? They won Bathurst revving between 5000 and 7000 for 500 miles without problems. You just have to suit the engine to the application. I operated the standard engines in much abused fleet cars for in excess of 300,000 k's without dismantling. The Chrysler Hemi 6 is a better conversion but will chew up and spit out any Series transmission in short order if hard used. The Falcon is the heaviest and bulkiest of the three and would be a last resort in my opinion.
