What engine conversion should i go for next??

[FinalD]

Is that you finalD? looks like an episode of bait car, drive it like you stole it

It is me indeed.

Mines a 2dr not a drop top, I might just use my 2dr as a daily (M42) and hopefully i can buy back my cab, i'll 2.5 or m30 that bitch

I thought I read in the OP you said it was a cab, great reading skills.

[age]

if you want a cruiser go all out with a v12

Ha ha ha ha ha ha, indian innit

[Rav335uk]

Has yours got a good exhaust note rav

Forgot about this video of my car.

Forgot about this video of my car.

I might get a mini cooper conversion instead

[blackE30indy]

Haha,them little mini's were tuned

[Rav335uk]

Haha,them little mini's were tuned

Most that run that day were

Most of the E30 M3's were doing the same times as my cab

[kangman]

Car looks lovely rav and sounds boss

[blackE30indy]

Your right rav,they were putting some good times down
I wana do a pass this year,I'll just spin up everywhere

[Rav335uk]

Mine won't be ready i think in time, but i'm going to try, but not rush it.

[blackE30indy]

Take your time rav,best do it properly,you can still use the cab
Any updates on yours ?

[Rav335uk]

Should be able to do some wrok on the engine now, as the concrete at home was done yesterday, and it takes upto a week to set properly
So off to the garage this week.
I'm in 2 minds weather to buy a mild cam for the M30 to go witht he ITB's though

[blackE30indy]

Ooosh let's get cracking then,
I would of thought a mild cam would help the top end
More,plus you plan on boosting later down the road,so would benefit there also

[kangman]

rav whats the sump clearance compared to an m20?

It's a good £450 for the cam

rav whats the sump clearance compared to an m20?

Same, never had issues with it bottoming out, but then the cab isn't lowered.

[blackE30indy]

Oooh that's dear,leave it for now then,then if you think it's needed,then you can think about it

[Rav335uk]

Yea, i'm not leaning to that idea yet.

I think the M30B34 cams are aggressive, and cheaper.

[hongkongfuey]

you might think of buying a 325 or something like that it would save the swap, and the insurance side of it would be better for a 325 rather than a modified 318is/325 it might be worth looking into that side before swapping engines

[HairyScreech]

If you want OEM look then go for a nice M20 in either 2.5 or 2.7/2.8.
The power expected from a 2.7 really depends on the head used, a 731 head really stunts the engine so bear in mind what head they have used when looking at power figures.
For a 731 2.7 around 180hp is normal and 190lb/ft, power will drop fast after about 5.5k as the inlet ports choke.
A 2.7/2.8 with the 885 head is around 190hp and the same torque, as the head flows a bit better the power hangs on to around 6k.
Fitting a cam to either (or porting the head which is a better fix) will see power over 200hp and torque around the same.
Fuel economy will be around the same as a 325 as the volumetric efficiency of the engine is better.

If you want more power and torque then go for an M5x in the same flavors as above, pretty much the same info but add 20hp to all the numbers.

If you want as much torque as an m30 without the fuel consumption then build a 3l M20 or a M5x 3l hybrid, both will be better engines than a stock M30.

The M30 is a really crude lump by modern standards, yes it makes north of 200hp standard but it does so by being 3.5l, they are heavy and thirsty and at best an early 70s design.
As nice as an E30 with an M30 in it is it really is a conversion that should be consigned to history, we have the larger M5x engines, the M6x engines and the v12 to fill the void of non stock engines and with options like that the M30 shouldn't even get a look in.
A stock M60B30 makes the same power and gives about twice the mpg of the M30, just look at the E34 535 vs 530 for example. (M60B30 215hp 214lb/ft, M30B35 218hp 225lb/ft, If we look at the M60B40 then its game over for the M30. The M5 also proves the M6x engines can build plenty of na power). The M60B30 returns ~25mpg and the equivilent M30B35 would be around high teens, both in a heavier E34.
Those that have done M6x swaps report high 20s to low 30s in an E30, the boat anchor would be luck to see mid 20s.

ETA - best not mention the M54B30 engine as it wipes the floor with the M30.

Got a girlfriend, cherry popped years ago and i'd rather 'waste' my money on my car then spend it on anything else.

I could pee pee my wages up the wall on weekend benders, or gambling, drugs, expensive clothes etc

But i'd rather drive up to the pub in my car for a weekend pint then come home pissed and calling my mates the next day to update me on what happended
I'd rather bet someone I can beat then off the lights then stick my money into a ladbrokes roulette machine
I'd rather stay on the ground and drive my car then be high and out of this world on drugs
I'd rather wear a primark t-shirt and buy some car bits then have a gucci shirt that i will end up spilling food on


you call it wasting money, i see it as it could have went to something worse..

This is exactly the way I see it!!!! Good man!!! At the end of the day, I have a fun toy in the garage which I own. Money spent on a physical object and not pissed, puked or otherwise shat away with nothing to show.
