thanks for that baly:thumb: i'll buy 1 me thinks. what am i checking tho?

Lol - checking the clearances on big ends and rods i would have thought as requested Wayne. Basically don't leave nothing to chance.

You will need Plastigauge Gap Clearance kit according to your clearance for spec of car.

Out of curiosity what have you had done to the crank and is it a centre thrust type or rear thrust, i''m assuming it's a centre from your profile?

Have you gone for uprated rods? if so what type?

rapid.STI 18 January 2009 06:41 PM

i know but how do i check em?
i am also on a budget build so using the same rods, the crank is centre thrust, its gone for a polish and rebalance

the car has the following
vf28 turbo i think
1.1bar
440 injectors
aps cold air feed
aps 3" uppipe
aps3" downpipe
aps3" full system
tsl tubular manifold headers
rcm pulley kit
rcm 5.4kg flywheel
exedy organic clutch
remapped by s.simpson at Gforce

Brake of a piece of Plastigauge and lay this on the journal you want to measure, make sure this is clean and free from debris.

Now attach you rod and end cap bolt making sure not to rotate or move the plasigauge or rod on the journal.

Tighten to the correct settings.

Once done release and Remove the rod and end cap to reveal the now flattened plasigaufe on the journal.

Now use the car supplied with the Plastigauge kit to obtain the correct measurement, this is done by matching the now squashed plasigauge with the marker line on the card supplied.

|If the measurement is between the line you will need to interpolate.

This is one way.
