My mate has just had a similar problem with his GT28rs on his S13 - Turbo dynamics reckon it was foreign body damage, but somebody else said that the EGT's had got too high at some point and caused the fins to start wearing away - which is quite possible, as he constantly had boost leaks so the turbo was working over time

I will work out the total cost at the end when i know the full costs involved :)

 

As long as the OEM parts/head turn up it should only be a few weeks, i am in no rush but it also depends on Tonys work schedule.

Still deciding on a turbo aswell, as i may go a little bigger :D

Steve dropped his engine off to me last week, but I didn't get a chance to start on it till Saturday morning, however we'll soon get it up and running again!

 

It started like this...

and a short while later looked like this....

It'll all be stripped and ready to have the bores machined for the 86.5mm pistons on Monday. :)

Some more parts arrived last week.

 

Oil Pump

image

 

Water Pump

image

 

New crank pulley

image

 

Gasket/seal set

image

 

Cambelt/aux belt

image

 

Flywheel bolts

image

 

Cambelt tensioner

image

 

Crank/rod/thrust bearings

image

 

Rebuilt head

image

 

I found my gear selector bushes had fallen apart

image

 

So i replaced them with these from Whifbitz

image

image

 

Another thing I wasn't expecting to replace was the RPS clutch, but unfortunately it was beyond use. So rather than going with the same again, I went for a Southbend clutch. Tony has this so it can be balanced with the crank this week.

I need to apologise to Steve for not posting sooner to show some progress.

A lot of what has been happening is a little difficult to show but a brief run down is:-

 

Block has been hot-tank cleaned.

Block has been bored out to 86.512mm (to suit CP pistons)

Block has been re-cleaned after machining.

The crankshaft, crank pulley, flywheel, clutch cover, pistons and rods have all been balanced.

The lower sump, upper sump, baffle plate and oil strainer have all been industrially cleaned.

The block has been painted black.

 

With that little list of jobs done we can get back to the more interesting assembly. Starting off with the piston / con-rod assemblies.

 

image

 

Here you can see where material has been removed by the balancing company:-

 

image

 

And here on the piston:-

 

image

 

The weight of all of the pistons and gudgeon assemblies were reduced to be the same as the lightest which was 0.418Kg's.

 

image

 

Next job was to re-fit the oil squirters:-

 

image

 

Then fit all the upper main bearings:-

 

image

 

As Steve has asked to fit ARP main studs I fitted the studs at this point:-

Next re-fit the crankshaft:-

 

image

 

Again you can see where the balancer has improved upon the stock Toyota balancing act:-

 

image

 

With that done it was time to install the lower bearings into the main caps and fit them. The ARP main stud kit needs to be torqued to 60ft/lbs when using the supplied moly lube.:-

 

image

 

Then with the crankshaft fitted it was time just before the end of the day to install the first piston:-

 

image

 

At that point I got the "tea's ready" call :)

Did a couple of small jobs on Saturday

 

Tided up the wiring where I removed the resistor pack.

 

image

 

Removed the old rubber clutch hose.

 

image

 

And then fitted a new braided hose from Whifbitz

 

image

 

Also drilled and tapped the exhaust manifold for a new EGT probe in runner 6, have got no pictures of that as it is being welded into place as well. Will get a picture when I get it back later in the week.

A little bit more of an update.

 

All of the pistons and con-rod assemblies are fitted and the con-rod cap bolts torqued according to their bolt stretch as given by Carrillo.

 

Next it's time to fit the oil pump and front crank seal, and check the clearance oil pump return clearance.

 

image

 

And the rear crank seal fitted into the old seal retainer:-

 

image

 

Next it's time to fit the newly shot blasted and post-cleaned upper sump pan, the sump baffle and the oil strainer:-

 

image

 

Time to say goodbye to the bottom end of the engine by fitting the lower sump pan, and fit the water pump:-

 

image

 

Not far now Steve! :)
