I have a LX 4door with a 202 and I have a fresh 253 in the shed ready to do a swap.
Im after some info in regards to what are the main things that will need changing to complete this conversion.
I have a new 3 core radiator, new engine mounts and recon M21 gearbox with 253 bellhousing.
What else will i need to make this conversion work?
Also, as i will need to get a set of headers and stock V8 exhaust manifolds are so damn hard to find (mainly the right hand side) where can i find a set of extractors to suit?
I live in WA.
Thanks in advance
Matt

You could go hydraulic...lots of people don't like them..but I think any hydraulic clutch is better by far than a linkage.
the only other thing will be tailshaft and v8 yoke for diff...its either that or stay with 6 cyl sized unis.

what i done was used a VH Commy V8 Bell housing, a commy clutch cable cut down and re-crimped and a UC 6cyl pedal as they have the cable HOOK on the pedal, Much easier to compress and it aslo looks alot neater and easier to adjust
The tail shafts are exactly the same, so no need to worry
Goodluck with it,
Cheers Marc

Well, I have both here, the 6cyl currently under the car.hi guys, am I reading this right re the tailshafts? I always thought the V8 tailshaft was heavier duty than the 6 cyl. I may be wrong so please ignore if thats the case.

Both shafts are the same length, circumference and feel like they weigh identically, only difference is the uni joints are bigger on the 8cyl shaft.
Haven't had a problem with 6 cyl uni's behind T350/Mild 308 for a number of months yet.

When I had my LX, years ago, I ran a 253 to start with, it had the standard 6 cyl tailshaft and uni's never had a problem, when I put the worked 308 in still ran the standards and never had a problem, but if you are going to drive it hard, do burnouts, it might pay to go the bigger uni's.Well, I have both here, the 6cyl currently under the car.hi guys, am I reading this right re the tailshafts?

Are you sure it's the RHS exhaust manifold? as they are the same as HQ onwards, it's the LHS that is hard. Just go extractors heaps better.

I know of a club member who not to long ago chewed a tailshaft in half whilst on a dyno machine....
I thought it was due to the 6cyl tailshaft being weaker than the V8 one but I may be wrong and to be honest have never seen them side by side to compare, I just took a guess that a V8 one would and should be stronger. perhaps it is all in the uni's...

well, i did a rather large skid and ripped the uni right out, the tailshaft fell down onto the road, my first reaction was...What the !!
But yeah if you going to give it a hard time or even have a torquey engine it will destroy the uni eventualy...
Same as rear control arm's, they tend to rip the hangers right off the floor
All good fun but

Hahaha damn, that's a good effortWhen i had my v8 lx i was running at that time a banjo diff and 6 cyl tailshaft....

Also, I posted in another thread awhile ago showing the physics of how having smaller width tyres will help save things like uni-joints.
