Hi,
You can get a 2TG up to 2litres. You get about 200cc increase from a larger bore and another 200cc with a bigger stroke.
Similarly you can get an 18RG up to 2.4litres with similar bore and stroke mods.

A 3T crank will get you up to 1770cc, not quite a 200cc increase but close enough. You can bore it out as well to acheive up to 2 litres, but the cylinder walls will be pretty damn thin at that point. Definitely not recommended in conjunction with forced induction.

on the 3T crank is there any special machining for the conecting rods and do you recomend stock con - rod or ??
also what size over bore do you recomend
.40 or .80 over.
also on the 3T crank did they come turbo and non turbo and is the crank the same for both ?

Hi,
As well as the learned people on this forum that can assist, you can also check out http://www.toysport.com/. Go to the "Tech Info" section for more details of how mad these engines can get.

89mm bore + 3T crank = 1950cc (or close enough)- Wiseco have pistons/rings to fit these straight off the shelf - this is a 4mm over bore for the 2T or 160 thou in the old money (a fair increase in anyones language).
Head gaskets are readily available from HK$ for the increased bore.
Depending on which block you have you may need to clearance the block for the longer stroke.
toymods search function is another place to look.

look at toysport as has been said, 18rg is not recommended to go over a certain capacity for its revving capability and
there are heaps of tech articles on toysport
