Another m30e30 & a new project

oh wow. ya. it's actually a reaaally good price.

is there any downside to this vs stock? is it proven? like any m30 racers reving to 8k and stuff? i'd buy it but my shit doesn't really make power above 6.5k even with the cat cam.

1v1 me old pac if my garbage ever runs

Your on for that challenge, I’ll be on historic rego from next year. This year it’s car trailer & being towed to the track

what's mrt?

Magnus racing team, they manufacture this is the trigger wheel & crank hub I’m using coupled with an ATI super damper

[LowR3V'in]

They can pickup what rpm range the crank starts to show higher levels of vibrations

let us know what they say.:up:

My big concern was weight on the factory damper/crank hub they have a habit of letting go at higher rpm. Hence the shift to MRT’s option

what's mrt?

Her one is going to make more power with a m30b35 & Garrett 3540r hung off it.

Great to see the engine coming back together Anthony. Will look forward to the other M30 project in the future, and good to see the trusty XR6 turbo proposed - I'd pondered one as a cheap turbo option for the M30 at one stage, should work well :)

I'm back dailying mine for the next few weeks while the e92 gets fixed at the crash repairers - has been fun driving it already.

They can pickup what rpm range the crank starts to show higher levels of vibrations, knife edging the crank the machine shop will be basically going back to scratch when they do the balance.

My big concern was weight on the factory damper/crank hub they have a habit of letting go at higher rpm. Hence the shift to MRT’s option, the current pulleys on mine though are down to just the alternator/damper just to remove some unnecessary weight

[LowR3V'in]

weird question. can the machine shop tell you what rpm does the stock crank become unstable when they do it?

[Anthony B]

I approve of all this.

This is why I’m here, keeping the m30 going haha

Past weekend could have been a success but I stuffed up one lead, going to say making ignition leads is one of my least favourite things to do. Need to order some more lead & connectors due to my rookie error

But 5/6 done, my fcpeuro order has cleared customs so a few clutch parts will be home soon



Ordering my booster flip kit soon, that’s now the priority job once it’s moved to it’s new passenger footwell home I can put the engine back in.

8k is pretty unbelievable but keeping stock 225tq to 8k it'll make 342hp

Is going to take some work to see it get that high, but the other bottom end has 144mm rods with 12:1 Pistons(being made to suit) , MRT trigger wheel and ATI damper, the crank is the the biggest hurdle but will be getting lightened/Knife edged/balanced.

The harmonics on the M30 seem to be the grenade point for them so the machine shop is balancing the rotating assemble to 10K.

peak torque should in theory be the 3500-4000rpm mark, I'm going to set redline at 7200rpm on this setup(rockers will be my weakest link I think). Version 2.0 I'm shooting to see 8k which on the big 6 will be wild

wowZA. Thats very good

[Anthony B]

When I was doing a bunch of M30 research it was clear that the engine responded very well to ITBs......all of the ITB cars made a significant amount more hp/tq than some of the stroker cars, etc.

It seems they like a decent cam, some good valve work/head work and ITBs.

I'm so excited to see this come together!

I'll be excited when it starts if doesn't sound like a box of marbles :nice:

after its dialed in I'm going to tinker with the head, looking at a PPF cam with a higher lift & the MM rockers the longer pad could mean really good things

Awesome M30, fantastic the soon to be wife is totally into it with you. Congrats on the wedding.

She knew what she was getting into haha, she has an e30 of her own we are diving into post me buttoning up my engine. Her one is going to make more power with a m30b35 & Garrett 3540r hung off it

what kinda rpms are we talking about here?
