Sloane's Engine Build Up

[bored33]

What size pistons? You going to use valve springs?

[GTRsean]

86.5mm so 20thou overbore.

He's getting tomei type B springs with retainers.

[bored33]

What other head work are you getting done? As you know, I'm thinking of doing something similar.

[GTRsean]

Just the head alone:

drill out oil returns

open up rear oil returns

hot tank

hardness test

deck, skim

replace valve guides

recut valve seats

CC combustion chambers

quick clean up of steps in the ports

polish combustion chambers

[r32-25t]

About the same as mine got, you don't need to do much to a Gtr head to make them perform and the amount of people who go backwards is ridiculous

[bored33]

I just wanted a basic service then slap it back in. Oh, and machining out certain flow flaws as well.

[Sloane]

Hello everyone i'm finally back from my long holiday

So here is a bit of an update on my build thread.

Over the last couple of months I have bought.

Tomei Type B valve springs and retainers

Garrett 2860-5's turbine housing both ceramic coated

Nitto H-Beam Rods

Turbo Braided Oil and Water Lines

Radiator Hoses.

1.1mm oil restrictor

Tomei Extreme Dumps

HKS Front Pipes

All my engine covers and exhaust manifolds back from Craved Coatings (Thanks Chris Awesome work!!!!! )

Twin turbo pipe also has splitter in it too.

As for the block and head it is still currently getting machined and serviced

I still have a few more things that need to be purchased still and I'm hoping my car is back on the road around march??

The covers are not purple just appear in the photos like that lol.

Here are some photos of the gear.

[GTRsean]

Block is currently getting grout filled to help with rigidity, and journal oil feeds drilled out.

Aim is Late Feb early March to finish car!

[r32-25t]

The covers look great, should be the good when it's done

[SHOWOFFR32]

Wow, looks good... Love the colour of the cam covers.

Good to see a quality home job

[Sloane]

Sean and I picked up the Head today.

Just fitted the Valve Springs in this afternoon.

Some other stuff I've got too.

HOR Cam Baffles

Tomei Extreme Dumps (Ceramic Coated by Craved Coatings)

[GTRsean]

Valves, tomei type b srings and retainers, shims and buckets are in.

Head just needs valve clearances checked once the cams are fitted.

[levinboy]

What cams are you going to use??

[GTRsean]

Hey Nick

Reusing his HKS cams, 264deg 8.8mm lift. Told him a higher lift would help torque but that would be more $$$ again...

They do sound like the tomei 260deg poncams I had in my 32GTR at idle though

Would even help a stock turboed GTR up GTR-S (-10) turbo equipped 32-34GTRS

It help's but nothing can save those things

[GTRsean]

Haha, maybe a 4.0L might.....

[GTRsean]

Just picked up the block and crank from the machinist.

Building will start soon!!

First pic is the block on the honing machine, the torque plate is still attatched to the top of the block.

[levinboy]

And people say you cant put things in the boot of a GTR

[ezy_09s]

Nice work guys but I would have done some port work on the head while its all apart ..especially on the exhaust side as its pretty average really.

Edited March 5, 2012 by ezy_09s

[GTRsean]

The ports got a bit of a clean up, removing steps in the radius etc, and that was about it. I didn't remove the 'humps' in the exhaust ports, just my choice .

Just to prove I ain't ripping off web pics, my ugly mug lol. Putting grubscrews into crank, loctited in to be sure.

Crank getting fitted and measured up for bearing clearances 0.0015"-0.002" from memory, thrust 0.011". Girdle torqued up, and you can just see the 3 long studs that have been shortened to clear sump and driveshaft tube. 55FT-LB.

Pistons and rods getting some attention. Piston rings clocked as per service manual.

Fitting the piston and rod into the bore. Rod bolts, I tightened them using a bolt stretch gauge on the 3rd cycle. 0.0055" stretch.

Today piston to deck height will be measured and if all good it'll all be put together permanently.
