20SEH into mk4 astra FAO ROB

[MattBrown]

What mounts and shafts are needed?

Must stay 4 stud, so im sure Bigblock is out of the question!!

[grubz172]

if you wanted to run small block then use the easly astra gm 1.7 flywheel(non turbo) and nova gte clutch pressure plate on an f15 box, the use your original shafts/hubs etc

[MattBrown]

So a flywheel, and complete GTE clutch? Friction and pressure plate?

[mowgli]

surely getting bits from a td or 1800 astra would be the best way, as the bits should fit.

[draper]

Aren't some 2ltr (I'm assuming there bigblock) astras 4stud anyway ?

[MattBrown]

Again, I have no idea, only thing I have done with a mk4 is a gearbox swap.

So, what engine mount do I use?

[mowgli]

big block mk4 astra ones... 1800, 2000, 17td etc

Some of the early big block mk4 astra's were 4 stud!:thumb:

[Adam]

1st question is, SEH why? lol

Mk4 astras have the drivers engine mount on the top of the inner wing/chassis leg, the mount bolts to the side of the block whereas old seh/xe bolt on the front.
Block would need drilling/tapping, but i think some blocks have already got the threads in place.

agreed.. surely an 1800 ecotec will be on a par with it anyway

An 1800 Sri would kill a 25year old shagged seh
Theyre crap in Nova's so in a heavy astra g will be gutless

Ive got an x20xev ecotec on an f13cr box for sale pm me

[MattBrown]

Sorted now hopefully!

Many thanks to Stupot, and his eBay cheapness of ways:):)
