New Cerb on the bay - M3 or LS3 engine?

[Milstad]

Cerb with no engine on ebay - would you go M3 again, or LS3?

This one?

Hum, not sure, probably stick with the same if a reliable engine can be found, as LS conversion costs a lot. However possible iffy wiring and what looks like mice have been in it?

It would need a very good look at

Well that was done in the Mule, so would be a very interesting conversion. They had to modify the chassis at the front but otherwise fitted.

Edit: I knew I had photos




You'd never know it was in there


Wonder what happened to that?

They rev like a bike engine with v8 punch not massive bhp but there great people
Are missing the point

People commenting to keep the 4.7…..It hasn’t got an engine though and I doubt 4.7’s grow on trees in decent condition so if you get a car with no engine you need to find an alternative surely?

define massive BHP?

My 4.7 puts out over 100BHP/Litre

Martin, I take it you would recommend a 4.7 upgrade?
Are you running the 4.5 induction or 4.2?
Emerald ECU with twin wide-bands?
I’m seriously considering an upgrade, but Jason thinks it’s unnecessary…

4.7 with 4.5 short induction inlets. ACT balanced headers, ACT decat and quiet back box, all large bore. The ECU is the latest from MBE with knock sensors, mapped at Powers. Dom grudgingly said it was the most powerful AJP they had seen bar non which seemed to piss him off a little as it was built by Jason at STR8SIX:-),

On the rolling road it delivered 405 ftlb of torque and 435 RWBHP. on the set up before for comparison it delivered 395 RWBHP which when tested at Surrey Rolling Road equated to 435BHP at the flywheel so the new ECU and a few Changes added 40RWBHP so assuming the same losses around 475 BHP at the flywheel if tested at Surrey Rolling Road.

The torques spread is epic, it just pulls like crazy above 2k RPM and keep going till the rev limiter and potters in traffic at idle quite smoothly.

It is a great engine.

[Imran999]

Wow, that sounds absolutely epic.
Thanks for taking the time to share the details.
Of course, now I need to figure out how to get there with mine ;-)
Thanks
