But everyone on facebook groups just want loads of power on cheap tyres, stock LSD so they have a reason to whinge about no traction and how when they roll into 3rd their wheels spin.

This is very true, i forgot about that.

Me on the other hand, i value my life haha

If you can settle for less power, a low 300kw rb25 is a lot cheaper to build/run reliably than a 400kw one.

You can even skip the whole rebuild the engine drama if you want to (head gasket is probably a good idea along with better valve springs if you are running decent boost), lots of cooling (engine and oil) and stick to e85 or add wmi for safety when going harder on it.

This. Achievable without going e85 ? I think i can live with 270 rwkw and a long lasting stock motor!

Hmm wait. .. Im already at that power goal. I meant to ask if it's possible for the stock motor to last without an internal upgrade at that power level without going e85.

I can't see why not. My setup was the same (excluding forged internals), it was so long ago, but I think it was about 270-280rwkw with the GT35r on a chinese manifold at about 16psi.

Lasted for 2 or so years before the engine upgrade. I thrashed the crap out of it too, but maintained it very well.

No dramas with the engine itself when my builder stripped it. The only issue we had was a crack in the manifold which was to be honest, expected.

Not to be a dick, but seriously, have a search on this forum. There is so much information at your fingertips. It was a goldmine when I was in your shoes.

Yes, but e85 makes for a decent amount of extra safety for not a lot of extra effort/cost.

300kw on stock tyres and suspension is mad fun.
