V8 V's V12

[deviant]

Yeah if I was looking to mod a 3 series BMW then I would start with the BMW engines.

You should be able to find their 6cylinder engines cheap enough or go with the 5.0 V8 they had in the old 5 series though I should image you will need to hunt around for that one.

There are plenty of people that have already done 6 cylinder or V8's in to BMW's so there is plenty of knowledge out there to help you. Trying to do something out of the norm could leave you stuck half way through facing a massive bill to finish or takeing a big loss and selling it all.

Alot of things can beat the 1UZ in stock form in stock car. They dont shift very well and bog down easily. However in something lighter with a better shift, they can be quite good.

a good BMW engine, V8's in particular, would be both expensive and hard to find. i reckon that's why he is asking

1UZ's are the best choice for forced induction, the 3UZ's have weakerer factory conrods.

if going N/A, get whichever you can afford.

the 4.4L BMW motors might be a fair bit more available and cheaper but the 4.9L M5 motor is going to be rare and expensive.

The 4.4L motor has been used in anything from a 5 series to a Range Rover when BMW had control of them so there would be a couple million of the bastards floating around the world.

M62B44
The M62B44 is a 4.4 L (4398 cc) version with a 92 mm bore and 82.7 mm stroke. Output is 260 hp (194 kW) at 5750 RPM with 260 ft·lbf (339 Nm) of torque at 3500 RPM.

The M62B44 has an aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses SFI fuel injection, has 4 valves per cylinder with VVT and features fracture-split forged powder metal connecting rods.

210 kW (282 hp) and 420 N·m (310 ft·lbf)
1996-1998 E39 540i
1994-1998 E38 740i/740iL
1994-1999 E31 840Ci

Plenty of them floating around the world, but not many in Australia and those that are here are going to cost an arseload more than a 1UZ. Also it probably won't be as easy to get aftermarket bits for them, eg bellhousings to suit common gearboxes.

I agree just saying they'd be a better option then the 4.9/5L BMW option though, an early 1uzfe can be had for around $1,000 so they are a very appealing engine in that regard.

Wait... so it has 400cc more capacity than a 1UZ, yet manages only the same power output and even less torque?

HI,

Thanks for the great response. A BMW V8 would be way to expensive to both buy and repair. I want an N/A feeling engine that is why i was thinking about the 1UZ. I do however like and think that a 6 cylinder engine is better and did think about the 2jz but want an N/A engine that puts out the goods. Any advice on how much power an N/A 2jz engine can put out would be good.

There is probably more options for performance parts and the Japanese do it well.

Thanks again.

i think 2JZGE is about 170kw at the flywheel, 1UZFE is 190. Gianttomato modded his 2JZ to get 148KW at the wheels.

Heh youre not wrong, it doesnt make any sense

Im pretty sure the correct figures there are 210kw/420nm, given the specs of the engine.

My totally biased opinion is that 1UZ-FE > 2JZ-GE

At the end of the day you have more power and torque, similar weight, similar (maybe even cheaper) cost and better chassis balance.

The only reason you wouldnt go for one that i can think of is if you have an issue with engine bay width

At the last dyno day a 100% stock 1UZ in a Celcior got 137kw at the wheels.

Yahoo have dozens of BMW V12's coming up all the time. They're a little pricey sometimes, but you can also get pretty lucky.

For Example:

And my 1UZ got 194kw at the wheels at DD14 with cams, ITBs, exhaust and standalone ECU. There's a lot of potential in them and I'm still a fair way from finding the limits of mine.
