4G63 rep strong lol
Tis a really good engine but idk if it's worth the hassle hey..
I thought of it too when my CA18 was giving me heartache.
RB20?
You can get them for free almost and they have direct acting cams unlike the SR20 and 4G63.
The advantage of SR20 is the alloy block and how far it sits back in the S13 chassis. Would definitely be an advantage to have the engine weight closer to the COG for motorkhana. Besides, it's bolt in!
I have an SR20 bellhousing if you want it.
Wish you weren't so far away.
Been looking for an RB25 box..
You wouldn't sell it would you? LOL
Freight would be a killer though hey..
I might be coming to Townsville for a bit of work soon, but I'd be flying up/down.
Anyway, back on topic... haha
