interesting gains for a small money


http://www.migweb.co.uk/forums/engines-transmission/434265-bigger-bore-3-0-v6-x30xe-money-well-spent.html


however,  still I would prefer turbo.. members with tig welding abilities and have the courage to cut slots on the block
can safely test 0.6, 0.7 bar pressures as its done.. but be careful about the wastegate

I am not one to cast opinion on mods. but what this guys done seems a lot of effort and dosh for not that much gain. 

[Webby the Bear]

Hang on, let me re-phrase......

Would the extra 30bhp what he's done be noticeable?

Yes you would know if you had found 30bhp

fair enough henry. £1200 though.........

its originally a 2.5 engine (reply #7) .. but later bored out and stroke changed so really considerable gain imo (more than 30 hp).. but still I would prefer the turbo route..

£1200 for 30bhp is actually pretty good value for a modern engine, although Mark's suggestions on the other thread are probably just as effective and cheaper to do without the restrictions mentioned by the OP.

You could probably achieve about 300bhp from a decent V6, using aftermarket cams, ECU(which would rule out use in an Omega), throttle bodies , properly developed ported heads and exhaust headers/system. The snag is that you're going to spend about £10k doing it, and a 300bhp small block(of any brand)  is about a fifth of that including the engine.

Fair enough chaps (and as mentioned i dont know much about modding).

just seemed expensive and time consuming. stocks the way to go

[Marks DTM Calib]

That thread is a bit unusual as the op had the restriction of having to keep the original block (for engine number and engine ID) due to his location, could be done much cheaper here.

Actually, I see no reason why you cant use a custom ECU in the pre 2.6/3.2 Omegas as the earlier superior injection setup has very little in the way of communication with other systems.

a custom ecu can be used.. there are cheaper models.. however still you have to re-wire all new sensors from scratch and I think you -may- still have to keep original ecu.. seen a lot of cases like that


full real standalones are expensive

Not too different to lpg then in installation terms

a bit similiar but requires more tuning mostly on dyno

You don't really need a dyno these days, to be honest. Fit a wideband lambda sensor and you can tune it on the road quite easily. My Westfield was converted from twin DCOEs to injection. DCOEs had had a couple of expensive rolling road sessions and much tinkering and still were never great. Fitted a Megasquirt and in an afternoon and about 30 miles on the road I went from no fuel map and a guessed ignition map to an engine that was running far better than it ever did on carbs. Much more flexible, a but more top-end power and a 50% increase in range for a tankfull of fuel.

OK, if you want to squeeze the last couple of horsepower out of it, then you need a dyno but, unless your corrections for baro pressure and temperature are absolutely spot on, you'll lose that edge as soon as the weather changes, so, IMHO, it's not worth chasing in the first place.

Something like a Megasquirt or Emerald will run a non-DBW V6 straight out of the box, probably with all the existing ancillaries.

Not on the 2.5/3.0 setup Cem

The only vehicle signals are:

Deadlock 2 code from the immobiliser - Aftermarket ECU does not need this so no problems there
RPM signal to the rev counter - After market ECU's support this.
Power
Ground

All assuming its manual of course!

Its the ease of interfacing this that makes the 3.0/2.5 work so well as a transplant unit.

hmmm.. that sounds like a plan    however,  I hear some negative comments on megasquirt    and was looking at the AEM EMS series


by the way, I dont trust those tuners here that they can tune the car better than the factory
