Ultimate 1.8 GTi engine.

Hi all,

 Just pondering really. I've got one project on the go at the mo but whilst changing the antifreeze on my GTi i wondered how far one can go with this engine and what its limitations are. I want to retain the 8v head and injection system though… 

 I'm prepared to bore out to 2.0 (is further possible?) but will not go down the cheaper route of buying a second hand block as i want the numbers to match up. 

Porting.. Does this engine respond well to huge ports? Will bigger valves fit without upsetting flow into the cylinders?

 What sort of power / revs can the crank / stock pistons / rods take?

 Are the pistons / rods the limiting factor on revs or does the valve gear bust up first?

Does anyone on here have a super duper GTi with a similar spec and can offer their thoughts on it? 
 
 Basically, money no object, what would be the ultimate 8v GTI? Not that i have any money, blimming redundancy took care of that but i'm working on it
 
 Cheers

   Rob.
 
 

I think TSR has done most things possible with a DX engine…..
