Oh, and FYI Rona makes 113rwkw with microtech and a built engine (minus cams) whilst stitts 7MGE (prior to GTE) in his wagon made 108 on stock management. My friend Crystal's 7MGTE (dead stock) made 125rwkw at last dyno day. 150rwkw out of a NA 7M is a big ask, but if you do it you'll almost certainly win the class at dyno day if you come up for it!

Well if specs are saying ~150kw at engine stock, then there must be a lot more loss along the driveline than I thought. What's a normal guesstimate between kw at the engine and rwkw?

PS Thanks Matt, nice finds

Ive always used 30% loss for RWD, just to be conservative. There is much debate about this and I guess it varies vehicle to vehicle. Some say as low as 20%!

Ahhh I see, I always thought it was somewhere around the 35kw mark

I've always used 15% Manual and 30% Auto as a guide. How accurate not sure but it generaly worked for my JZA70
