Hi all, My mates second car is as states in the title, a E30 318i. We put a RB30 in it for a bit of a project, it was more of an impulse kind of decision. . Now im thinking, when engineering time comes, is that even legal?? --------------------  |

But that didn't answer my query. . just wanting to know if it is legal or not, not if the RB30 is a waste of time. for a turbo car for it to be legal its the weight of the car x3 which will give u the max ltr size engine u can use |

meh stiff the RB all together and put a M20B25 stroked to a 2.8 with a M52 crank, and either turbo that or put some ITB's on it! |

ROCK ON R~R |

I do however know of a bloody quick M30 with n2o but we all know you cant run the bottle legally up here in QLD |

yeah ive seen some bloody awesome M30's in e30's, but i suppose if you want a street car and not track, the RB would provide more HP. |

Only reason to not do up a BMW with BMW parts is if you're a poorby arse. Flame suit on |

Australian Design Rules state that an engine may not be fitted to a vehicle where the engine is older than the car. RB30 blocks into R32/R33/R34 etc is legal as the motor was originally fitted. |

RB30 blocks into R32/R33/R34 etc is legal as the motor was originally fitted. Think you will find an RB30 from a VL or R32 Skyline was before this BMW was made  Therefore, the legality is questionable...The true indication is getting it mod plated due to the change in engine capacity(more than 15%) so the person you need to talk to about it being legal is an 'Authorised person' from the Qld Department of Transport who is the person who will be fitting the Mod Plate They are the ones who can tell you which hoops to jump through to make it 100% legal or even if they will pass it This. Best bet is to actually ring the QLD Department of transport and get the correct answer as opposed to the conflicting stories from SOME people on here who have no idea... Dale, I already asked you nicely the other day NOT to post your shit in here unless you have something constructive to add. Do it again and i'm going to suspend your account for 6 months. Capiche? |
