THink thats all i'll need, any checks i should carry out?? and anything I should watch out for?? Is there a guide on here, as some of the guides on here are great!!{thumbup}

i just rebuilt my motor swaping in all forged internals.

u will need/i would do

1. coolant
2. head gasket
3. gasket maker for oil pan (great stuff i would recomend)
4. valve cover gasket
5. new spark plug o rings
6. 1.5 gallons of distilled water
7. depending on miles, do all belts
8. lots of break cleaner
9. regular oil (about 2.5 gallons of it because i would sugest changing it after about 20 miles)
10. 2 or more oil filters
11. ball hone

check injector seals
bring head to machine shop and make sure its flat
check all valves
valve springs



im sure there is more so people can add to this list as the thread progresses on.

thanks alot mate, i have all the gaskets, belts are just a few hundered miles, i just changed them using the guide on here along with my cams.

:cool:

check the basics, measure the pistons per the makers specs, figure out your ptw clearance.

verify your small & big end clearances..big-end side clearance, verify your piston ring end gaps, be certain to knock off any edges on the tips after grinding to clearance....put plenty of oil in the ring grooves......use a decent lube on the rod bearings prior to assembly.....be certain that the tips of the piston pin c-clips dont have any sharp edges, as they may want to pop out if not seated correctly....i forget if the evo rod is centered or if htere is a offset......be sure that is oriented in the correct fashion or you'll side-load the assembly if not...

here is the thread with the details to my build. sorry for the way the pics were posted, i didnt feel like re-hosting them all so i didnt. and dont mind all the haters either. haha

think im goin with a ETS GT3076HTA Kit

thanks guys!

anyone else

I'm interested in this as well.

What about the balance shaft? does changing the weight of the rods and pistons demand removal of it?

Also, when doing a "drop-in" like this, are you going to change the rod bearings so that you put a brand new bearing against a worn-in crank (Bad, as far as I know) or match up the bearings on the exact spot they were on the stock rods to keep the mating surface on the bearing face the same (between the rod and crank)

+1

im fitting new rod bearings, thats what all cars in the uk that gave went this route have done!

what kind of hone would you use on the bores?? Also am I ok to use new rod bearings on a used crank??

Is there no worries / problems when i change the OEM Pistons with Wiseco 85.00mm Pistons? Or i have absolutly go 0.20mm over OEM

The car has under 25'000 mls
