Usually done on the stroke shim, as per the terminonlogy, the stroke becomes bigger which in turn uses more of the cylinder. Thus increasing cylinder capacity.

Different crank, pistons and rods used.

Rebore is different, using same size rods, but bigger pistons, same size crank etc, thus creating more cylinder space, some engines, such as the M3 will not accomodate a rebore due to size.

I did consider a full build and stroker before selling the CSL, but if I do it it would be on normal M3.

What do they drive like? Good on track but shit on road?

I must admit N/A 450 bhp in an M3 sounds good.

I guess good thing is that you only have mainly engine mods to do, not other bits and bobs like you get on a charger engine or transplan of V10 or V8

Just need a donor engine that has some like left in it?

Like we almost had ???

Would increasing the stroke not limit the top end revs?

If you use the VAC stroker kit that is based off of the ALMS M3 PTG race car mod you will want to go with the BMW AG Motorsport cams 316 and I wanna say 304? When you do the big cams you need to delete the vanos system. It gets in the way of the larger cams. Also the factory race cars didnt have a mass air sensor, they did use a carbon intake similar to the CSL just no giant flap to worry about before hitting that side ways filter. Also BMW AG Motorsport offers a less resteictive filter for shorter events. Incoming Air was monitored by the stand alone EMS by Motec. I have some spares of the larger cams from BMW AG Motorsport division if anyones interested?

The very first E46 M3 GT race car in the ALMS made its appearance in 2000. It was a wide body GTR powered by the S50b32 that Thomas Milner owner of PTG had stroked out to a 3.4 liter. Then came the prototype P60b40 in 2001 and the inline six dressed the same as the V8s racing right along side oneanother but the obvious difference showed in the performance. Later in 2004 came the P54b32 race engines producing 420HP FROM 3.2 LITERS. BMW. AG Motorsport offered an evolution kit to the P54b32 bumping horse power to 437 while still remaining at 3.2 liters.
