is anyone running one of these on a uk 2000 classic with standard internals or is it best to go with a 20g

 

Gearbox?!?

 

I expect the gearbox would cry, just before a big end decides it wants to escape.

Someone on here (can't remember who) claims to have circa 450BHP on standard UK turbo internals, howqever the common consensus seems to be low to mid 300's is the limit of the engine and of the box.

 

took me 14months to blow up my MY00 bottom end up with an AFP 18g...a 20g or 321 will tear it a new one; stick to a 16g for a little longevity

A 16g may very well lunch your gearbox though

 

am running a ppg kit so no worries there

 

Just the engine to worry about then.

 

dude for another few hundred quid you could have one of these https://www.scoobynet.com/trader-ann...r-engines.html then run any turbo you want after that

 

I'd go for the 18g and watch your boost levels i that case...but be aware that you WILL break it at some point
