MG Maestro Turbo 400 bhp My Blog

[charliecosworth]

well good news and bad clutch has started to slip, so turbo been backed off, still done 313 bhp, another job next week stage 2 clutch, guy was very happy how everything was and put together engine seems very strong and put out lot more power with better clutch fitted.

to say its fast is understatement !!

[Mike Brock]

I knew it would go beyond 300 with work and parts you put into it. What's it like to drive then - description please.

Higher rev limit may also help the power. Standard ECU's are either 6500 limit or 6700 limit (The internals are the same) so I'd consider upping the limit to 6700.

That plot looks good fun! The opel kadett looks really tidy next to your car too! that's even more rare than a maestro around here.

also going to change the 5th gear back to what it was, whilst it's good cruiser now on the motorway, problem is nearly doing 80mph before turbo starts to play (not on uk roads of course ) which makes lot of turbo lag.


even at the moment car is very very fast, not for faint hearted, pulls all over the road 1st 2nd 3rd torque is unreal.

will update has it comes along

was very lucky today, decided go out MG today noticed small amount of oil on floor in garage, checked the oil was just below the min.

looked under car seen small drip coming below bottom cambelt cover decided to take apart to find this..



oil seal just about to pop out, if i never noticed oil on floor, god knows how long before popped out all together dumped all oil and sized!
Wouldn't of been happy 5k engine sized on motorway

did change the seal only 2 months ago, can't understand how its happened

[Mike Brock]

Very lucky indeed. Wouldn't the fuel pump shut down with low oil pressure?

[charliecosworth]

yeah might of done, just the thought of new forged engine with £1,000 turbo even running with low oil pressure scares me.

[E_T_V]

This is fairly common when replacing the seal I'm led to believe. I think you are supposed to loctite the seal in place when fitting it.

[Mike Brock]

Hi Peter - regarding the arp studs you have fitted - do you just bolt them up to the block first - then slide head into them?

Is tightening sequence 30/60/90 ft/lb?



cheers

[countrydude]

o series values will be different Mike, I'd contact arp direct and ask, they must have an email address.

[Mike Brock]

Hi Phil - the arp studs I'm using for my O-series are T16. Right enough I should email them.

cheers

Just hand tight in to block, then nip with Allan key then slide head on, not had any problems myself, they do come with instructions and apr thread lube

[E_T_V]

Lightly oil threads into the block and nip in either with double nut or allen key recess if they have them (newer T16 ones do - the old ones don't).
Critical to apply moly grease (or supplied lube) to the nut threads and under the nut heads as otherwise they gall on the head surface when tightening.

[ian drew]

Regarding using better head bolts, do T16 ones fit the O-series? I only ask as I will want some soon (hopefully) and T16 ones are more readily available.

Cheers,

Ian

ps I hope my engine will be as clean as the missus allowing me to have it in the kitchen :-)
