Bugger...block was no good.

Dropped into C-Red this afternoon to say Merry Xmas et al. Marc started out with the bad news when I arrived...the block has been machined too much from past rebuilds and can't be used. Then he delivered the good news in that they'd already sent another block off to them. Apparently the workshop floor looked no dissimilar to how a South African lions meal looks like after tearing it apart with oil, coolant and SR20 gizzards all over the place to not stop the rebuild train.

Many thanks to Boney for getting this done quicksmart.

See you on the other side of New Years.

Cheers
Brendan

Short Block sent to engineers for Rebuild

Just got word that the short block and related parts have been sent off to Heinz for it's rebuild where it will be fully balanced and blueprinted (a lot of the parts are already done, but assume it will be done again).

It doesn't mean it'll be started immediately as I believe there's a few engines already in the queue before me. But I'm excited anyway.

Cheers

Tomei N2 Oil Block and Nismo Reinforced Release Pivot arrive

A few pieces that I got from eBay have arrived. After an initial problem with the first order being made and the seller not actually having stock, it was cancelled and re-ordered with another ebayer after confirming they did actually have the stock ready to deliver.

The first and more blingy item is the Tomei N2 Oil Block to replace the standard Nissan Oil block made for an oil filter, not oil cooler lines.

Here's what the Tomei website say about it:

The SR20 engine's oil block tends to fail due to the weak oil filter sensor screw which oftens breaks. We at TOMEI had found the problem while we were competing in professional N2 race series over 10 years ago. So we designed this upgraded product which solved the problem. THis was later discountined but due to it's extremely popular demand we decided to re-release this product with a new design. Now lighter than ever before and has the ports for the original OEM sensors for direct fitting as well. The failure of your oil block can lead to disasterous results with terminal engine failure. With all the time and money spent on your race engine this is an absolute must have upgrade to protect your investment. Especially with engines running a sandwhich plate or similar oil cooler this is an essential safety precaution.

- Tomei N2 Oil Block box
- Oil pressure sensor (oil temp sensor is on top)
- Back of Oil Block - direct flow to lines
- Extra parts supplied - #10 dash fittings and mounting bolts

The other item is to replace the little thing that broke and started all these shenanigans. Back in June, the standard Nissan clutch fork release pivot failed after being hammered most of the day at Barbagallo Raceway. It was more than likely the same was originally fitted to the S14 5-speed box from factory and wasn't really something made for punishing use with a twin plate clutch. Again, in hindsight I should probably have replaced this item when the clutch plates were replaced in March this year. Again...meh.



So this is the Nismo Reinforced Release Pivot that will now be taking a pounding under the clutch release fork.

- Box for the Reinforced Release Pivot - Part Number 30537-RS540
- Instructions showing torque settings and other cars it fits

That's pretty much all the crucial bits I need at this stage, one final item I will need to get will be the replacement silicon hose that I went and replaced while at the track - it was bright blue, and I'll be replacing with a nice black Samco item to match the rest of them.

Have a Merry Xmas and drive safe.

Cheers

CP SR20 Pistons and S13 SR20 Oil Pump arrive

A couple of other items have arrived in the last few days being the pistons and oil pump. Firstly the beautiful CP Forged Pistons setup for 9.0:1 compression ratio and 3.425inch (86.995mm) bore diameter. These will replace the standard Nissan Z32 pistons from a VG30DETT which were in the engine when it was removed from the shelf in its original rebuild. In hindsight, a set of these should have gone in originally thus why we're doing it now.

- CP Pistons box
- Label on side of the box (Shelf Part SC7326 / Serial 114465)
- Four set of rings
- Close up of rings label - CPN-3425
- Gudgeon pin circlips I think
- Piston specification sheet



- Underside of CP Piston
- Another side closeup of piston



Of course the other main item that's been shipped over from Japan thanks to Nissan is a brand new Oil Pump for S13 SR20. This will replace the problematic GTi-R Oil Pump that was fitted the first time. It was a constant problem leaking oil mist down the front of the engine and making a right mess. The new pump will be mated with the Ross Tuffbond Metal Jack Harmonic Balancer that I've already received.

- Oil Pump box
- Closeup of front cover serial I think
- Embossed Nissan logo on cover
- Oil pumps main seal
- Oil pump gears/rear of cover

The oil pump gears have been sent off along with the rockers to be cryogenically treated by Lou from Cryogenics West given both items of better chance of survival under the beating up they will get with "increased wear resistance, enhanced durability".

I have the Nismo Reinforced Release Pivot and Tomei N2 Oil Block on order and just waiting for them to get delivered.
