Yeah, unless you want to put a spacer plate in to lower the compression but i don't know what you're planning

If you can bear it,have a scan through my build thread.
You would need rods,pistons,uprated bearing shells and check the crank for a bottom end build and then for the top,the best is the Ferrea valve train plus springs and guides.
You now have a good choice of parts from people like IE and PEC who supplied most of my parts.
Most recommend using standard CR pistons although saying that I went for a 9.2:1 set from Wossner with the eventual power and boost in mind.
A WMI kit makes that less necessary.
Gonna have to book a day off work to go through your build thread lol
Have u done anything to upgrade your gearbox Alex ?

Gearbox was rebuilt a couple of years ago.
It had always been a bit noisy from new,but coming from a straight cut box on my Escort I didn't think much of it until it really got bad.
When it was stripped down there were a lot of brass filings,and the selector forks and synchros on 1st through 3rd were worn.
As a bonus,the transfer box was basically toast.
So....it was rebuilt with uprated bearings and forks,and the transfer case was replaced,and since then(fingers crossed),it's been absolutely fine.

If you look at the spec list,it's not far different from what's been done to mine.
Uprated bearings,synchros and selectors.
Admittedly they also uprate the input shaft and few other bits,but I can safely say that mine is dealing with 540lbs.
The dog box kit they offer looks very similar(if you know what I mean) to the SQS parts.
No idea mate well over my head just seemed like a decent price for the hole box when mine gives up

Firstly,it's not a kennel.
Second,this probably explains it way better than I ever could.....

Quite honestly,if I needed a significant upgrade,I'd get a DSG uprated and fitted,as Decked has done to his car.

About the same as a dog box conversion but with the advantage of being a lot more user friendly.
Think that's a long way off for me , think the uprated box would do me if it eventually goes
