A word of warning to everybody Jim Berry from Competition clutches in Brisbane sometimes referred to as Brisvegas found out the hard way on his clutch dyno there are now issues with some of the better brand name fasteners.

He had fitted "Unbrako" brand in-hex bolts to a clutch and felt something strange happen to a clutch he had just built when testing on his clutch dyno and found the bolts had stretched but not yet failed.

It seems that our old friends the Chinese are supplying sub Standard steels to some subcontractors even decent brands such as Excedy clutches he has found recently when rebuilding pressure plates for customers with race cars that the pressure plate diaphragm springs seem to be loosing way too much pressure compared to previous years when a customer returns his clutch for an overhaul for the next season of racing.

So a word of warning if at all possible try and source genuine Nissan Datsun bolts, Jim had to rifle through his scrap bin and retrieve the original Nissan pressure plate mounting bolts to finish the dyno test on that clutch

On my first 120Y (B210) 4 door I used Ford escort Bilstein group 4 spec shocks worked very well, With the popularity of historic rallying these are readily available these days

Bronze valve guides will not last like stock chilled cast iron nissan ones so look at wear in that area and replace with stock nissan if worn out, If as new then use till worn out and go from there

Chinese knockoffs better to use second hand genuine bike carbs and CV vacuum type will be more forgiving, Just remember with CV carbs the idle and main air jet sizing is critical to good performance and driveability.

Many do not have replaceable idle air jets I use Yamaha Banshee quad idle jets for which I have the appropriate tap and then drill them to suit, The banshee runs fairly small idle jets and having modified and jetted many banshees I have many spare stock jets to modify and they will fit most CV carb air jet holes.
Then there is Emulsion tubes main jets pilot jets main air correctors needles etc to work with so more like jetting webers than Su type carbs springs are hit and miss as not listed as options and have to be sourced from other CV carbs but when dialed in work extremely well as a weber replacement.
Then again bike throttle bodies and a megasquirt will be always preferred for ultimate driveability and performance

Here is a link to a pdf article on the Australian Rex Bunn developed breather system used for classic motorcycles but relevant to any engine especially high RPM engines, You can also search for and read the patent documents to gain a better understanding of engine breather systems and work out how to improve you own system.

Rubber spoiler ? the bit on the boot looks somewhat like a Ford Escort RS 2000 part not the ends though so probably a homemade fibreglass one

Get hold of some engine parts catalogs and work out what other engines pistons will work, You could be surprised at what will work sometimes.
As examples I have used Mahle forged VW pistons in a big bore L20 B at 90.5 mm reliably and also a grunter 2300 L series stroker that used Honda XR500 pistons being very light pistons that 2300 ran an easy 1000 RPM higher than normal strokers did at the time.

Otherwise use these guys the same people all the top race teams in Australia use

Most do not know that a Cosworth BDA crank will fit into an L series if you use 40 thou under main bearings, that will allow an L16 to run reliably with the right pistons and rods to 10,000 RPM that will be very sweet music indeed.

I ran a 1688 at 9600 RPM for about six months until a Rod Bolt stretched and broke destroying a genuine L 14 block that was with a normal L18 crank and 83mm bores, research into the Cosworth crank came out of that failure a guy I knew did it in an Australian formula 1600 class single seater and it was reliable and quick.

So there is another option out of left field, I also know about FIA heads mine was built on a L20B Japanese block bored to 90.5mm with a non thrust face wall thickness minimum of 6mm after boring the FIA heads make awesome torque but lots of luck finding one these days under 10K, I paid $700 for mine at the time off a speedway guy with pipes and manifold wish I had kept it but I know who has it these days in a 1600 it was in the ex Sheka Mehta Works PB210 I once had which is now getting rebuilt down in the Bega valley in southern NSW.
the original LZ14 went into Geoff Portmans Bluebird project who knows where that engine is now, I got the PB210 off Geoff

1200 Ute I built with a mate with a Z18 turbo we used VW Passat Wagon early type rear shocks from Koni fitted and worked well, That was built back in the early 1990's and featured in fast fours maroon ute with Simmons rims.

Mongrels who bought the ute of Paul claimed they built it a retraction came in a later issue on about page 48 you get the idea "Blah Blah we can only take people at face value when they tell us something" it would help if they had made a retraction in the editorial and exposed the low lifes who claim others work

Funny there has been over the years many a heated discussion on the Society of Automotive Engineers about whether or not to hone a used cylinder when re ringing, The Jury is still out as they post up various real world oil consumption and power figures for both methods.

I work on the theory that if there is a wear lip that can break new rings do the rebore and plateau hone method to bring it back to the factory specifications and therefore only use a bottle brush flex hone for the plateau finish after a run through the sunnen machine to hone to size that gives increased lifespan over conventional honing
