good info cain was helping a guy with his project car.He was wanting a rear whhel drive setup,and i suggested the engine from e30,s he asked me about m10,s and m40,s...intersting to note the m30 and m60 are only a few kilo,s different.

Edited September 29, 2004 by kiwi535

Nice info.

Note here that the M44 is roughly the same HP, if not even, with the 2.0 six cylinder.

Take into consideration the Power to weight ratios, they are not to shabby. I got one, and am fairly happy with it. Got a few motor mods I'm doing soon thou.

So explains why they are faster to 100 that the six.

Not bad for a "round town" car ( as advertised )

:thumb:

[Guest Spargo]

The S70/2 was never intended for the M8, When Paul Roche was appoached by Gordon Murrary about a motor, that's what they built. It's completely designed to Mclaren specs (with regards to size)

Oh, and it will fit under an E30 bonnet :mosh: :mosh:

cept the torque is a fair amount less

the m30 gearbox is also bloody heavy which is the concern for e30 m30 swaps.

cool thread, gotta love the M102

[cainchapman 0]

Don't remind me about the S14 thanks.

I was going to have a look at a 320iS (Italian) 1990 in Diamond Schwarz in Oxford UK in 3 weeks. Just been told this morning that it was sold. :banghead:

Oh, well. I guess I'll find something fun to drive next.

[petone 0]

C'mon guys, you think I'd drive a car with less than 100 hp?

M10B18 is 105hp :mosh:

I'd also like to point out my car is faster to 100 than the auto 320i

[m325i 705]

My bro has an e30 318i. With one person, to 100k they are ok. Definately good for a 1.8. Fully loaded up a hill, "fuhgettaboutit"

[petone 0]

Haha i was going over the rimutakas with 5 people in the car once, actually felt sorry for the car. It made it though

[Gus 5]

drove a facelift 318 the other day...i much prefer to pre facelift

no its not - they make like 40 - 45 kW at the wheels.. Yipee. Even a 320i ain't 100 hp at the wheels.

[petone 0]

I'm going by the owners manual here, same for the 0 to 100

[Guest Andrew]

owners manuals lie.

[*sic 1]

owners manuals lie.

so do most of the ownes when they find the real hp figures they are placing on the ground!

[Grant 4]

so do most of the ownes when they find the real hp figures they are placing on the ground!

aint that the truth.

[Guest Andrew]

so do most of the ownes when they find the real hp figures they are placing on the ground!

yeah.. know this.. 325i don't make more than 95 - 100 kW on the dyno at Gavin Bellars place. Has anyone else noticed his dyno gives low scores?

Cain your car got a higher score at Torque Performance didn't it?

[cainchapman 0]

Yes, correct. David's car was 93kW off memory and mine was about 7kW lower than the 164kW I got from Torque Performance.

However Dynos are not that accurate anyway unless you use one of International Dynomometers ones.

Therefore, you need to find someone who will look after you and keep getting your car dyno'd at the same place so the records have some correlation.

I agree - dynos are not for comparing power - so many variables. Really for tuning.

Hey talking about the rimutaka's from a thrash point of view - is anyone else disapointed that a lot of the good corners were taken out....... maybe it's just me

Thanks for the info everyone........sooooo, next time a S70/2 turns up on Tardme, can some one give me a yell - haha
