and whats those particles in the paste on top of the pistons?

and again just motor oil when fitting the pistons nothing else, kept it very clean while assembling

cool, good work - cleanliness is key to a bottom end that doesn't smoke

[tinkerbell]

just looks dat way in the pic

yeah, thought so...

BTW - whens it going to be kicked in the guts?

[EKVTIR-T]

atomic batteries to power

turbine to speed

ready to start up

[SLOBRO]

see how this looks? lower sleeve looks looks wider than upper sleeve edge?

Attachment 22113

hard to tell whether it is equal on both sides without using a caliper to measure

that looks very nice was it sleeved??



here a lil better pic

i have already started the car a couple of times once a week atleast till i get it tuned and driven it up and down my street OMG soo much better than my b18c2

[tinkerbell]

no, not sleeved, no need as only pushing 160kW

yours looks fine, if it was bored by a proper machinist, it should be fine...

what is the P2W clearance? bearings clearance?

FWIW - i started mine, got it up to temp, checked for leaks and shut it down, then i drove it 50m up the driveway to a tow truck and had it run in on the dyno... seating the rings under load is crucial to longevity...

as long as you don't beat on it with unknown fueling, it is OK, but you don't want to risk it IMO... run it in on a dyno and she'll be apples

I would like to know who offered you this service too.

[SLOBRO]

ive called a couple of place some places from 1100 dats just the first tune breake in extra 300 and some places 500 lol

[tinkerbell]

dyno break in is 400ish plus full tune around 750 (plus 40l of petrol), so 1.2k minimum is a good ball park (i am a regular customer of his...)

takes a whole day (at least) of effort by the tuner... anything less and you know it is not going to be done right...

Toda Racing Australia did mine, very very happy...

but when fully building an engine, you have to realise you have to pay for a tune to match your ECU to the engine combination that you have "created"

people who think they can run a 'base-map' and pray for the best are way behind the eight ball...
