@ajmacdon That's a very interesting power plant. What kind of HP does it produce in stock BMW trim? Do you have a build log on this site? Cheers, Lonnie |

Cheers, Lonnie It makes between 210 and 270 HP in factory trim with about 6 different power ratings in between depending on model and year. The long blocks are all 100% the same including cams. There were two intake manifolds and about 5 different engine calibrations to make all the various HP numbers. Basically any N52B30 engine should be able to make 270 with the good intake and the right calibration. I haven't started a build log on this site, I'll copy what I've got going on a smaller site over here. Thanks, Alex |

It's an "magnesium block" that's about 50% aluminum... |

Still, it's 22lbs lighter than the 100% aluminum block so definitely nothing to sneeze at. If we use this logic I believe a honda with cylinder liners is half cast iron as well, no? (I thought you had liners installed your motor, I might be totally wrong but you get my point.) Alex |

Does anyone know what the weight of the Ford 2.3 Ecoboost is? From my research, on the internet, it looks like the Ford Ecoboost 2.3 is about 300lbs dressed. That's more that I would have guessed. |

There's one easy deciding factor between the 2.3 and the Bimmer engine for most of us, is there an easy harness or way to use the Bimmer short of a megasquirt? There is an ecu and harness for the Ford engine. I haven't looked at dunks or power specs, but from the fact there is even a comparison that must mean they are similar in power outputs. |

For me it was turbo -vs- non turbo. I just don't like a turbo in a small car like this. I have a turbo SR20 Nissan in my other car and it's tons fun but not a power curve that's friendly to a very organic driving experience. Not advocating the Bimmer at all, it's not for most people, it was a really tight squeeze for this car and needs a dry sump. I also agree that if you want a pre-packaged engine management the BMW is NOT the way to go, lots of wires. However, if you want near 300hp without forced induction or 9000 RPM there aren't a ton of lightweight options, this is one of them. Alex |

I know the pics are kinda crappy, but this is the 1.8t VW engine complete with manifolds,turbo, and alternator (no clutch). |

That's lighter than I've been led to believe it would be |

When they design these blocks they do it for the long haul and use them worldwide. There are now also a couple of options for RWD transmissions. |

Doesn't make the chevy seem so big comparing it that way. Of course you would need a heavier diff. That might change my plans. Just happen to have 1. I thought I'd pipe in with some SR20DET information since I have quite a bit. Here is an SR20DET bottom end with an SR20VE head (a tad bit heavier than a DET head due to the VVL stuff, but probably no more than 3-5 lbs). Engine has a Quest 120 A alternator (1.2 lbs heavier than stock), aluminum crank pulley, no upper intake manifold (4 lbs). No flywheel or clutch. Weight as seen is 254 lbs with some of the chain on there, so about 250 lbs in reality: Engine full up ready to go minus wiring harness (which is 5 lbs for the engine - from scratch harness). This has a 7.25" Tilton cerametallic twin disk, AP Racing flywheel (~8 lbs), stock SR20DET 5 speed, Quest alternator (120 A), VVL head, Full-Race twin scroll SR20VE manifold (~14 lbs), Borg Warner EFR 7163 T4 twin scroll IWG turbo, engine mounts, trans crossmember, and shifter. So as full up as it gets minus wiring harness (5 lbs). Weight as seen is 423 lbs: A stock turbo manifold is ~9 lbs, or 5 lbs lighter, stock turbo is about the same weight, as the bigger EFR has an aluminum center housing. A stock flywheel and clutch is probably around 18-20 lbs heavier. A belt driven PS pump with bracket and pulley is 7 lbs. I was using an EHPS from an Astra, but went to the belt driven pump later. I'm not sure where the high 400 lb ranges I've seen, as even going with a heavy flywheel and PS pump, you're at around 450 lbs. Maybe with an AC compressor and bracket you can edge up near 480 lbs? So that's what I've got. I used two bathroom scales that seemed to agreed +/- 1 lb in the 170 lb range, so I'll call the total weight +/- 3 lbs, but has a bit of wood and chain on it, so they're likely a bit high to reality. |
