Don't forget the $5k + that you will need to drop on brakes, tyres and suspension'.

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.

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!

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.

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.


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

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
