With this engine I wanted to get rid of the open ITG filter on the ITBs and enclose the whole setup. The plan was to make an airbox from two sections, an upper which matches the Jenvey backplate, with the biggest inlet pipe I can fit (5"), down to a front box containing a panel filter. I...

Flywheel, clutch and gearbox could then go back on then be lifted back into the car. At this point I decided to change the water outlet from the block to an AN style fitting rather than the OEM hard pipe that is three times the size. AN12 fitting welded onto the end and bracket made. Then a...

84.5mm bore really is the maximum possible with a stock headgasket. The head could then be dropped on and torqued down. Then the lifter trays, cams, upper chain and tensioner. At this point, I spent some time measuring the actual physical valve clearance 10-15 degrees before and after TDC...

With the rotating assembly in the block it was just a matter of bolting everything else back on. First was the oil windage tray, pump, and new oil pump chain tensioner, then the main chain guides and the front timing cover. The sump could then go on, and bottom end transferred back to the...

Yeah. Similar issue with K20s which tend to vibrate every last bolt on the head and block loose past continual use over 8500rpm. Doing 2-3 hour endurance races @ 250hp we finished with the idle control valve missing, the alternator bolt backed out and various other things on a number of...

There is a 20kg difference between alu and iron blocks. Been there done that I'm afraid to say over the years (n) Pulled both OEM threads, and pulled timeserts out, you either get lucky or you don't with them, the issue always seems to be the area around the hole, rather than the thread itself...

Tapered ring compressor makes the installation painless versus the cheap universal ones...! More soon!

Next job was to check the main journal bores for roundness with the main caps torqued down. These were fine as I expected, with the previous bearings coming out in great condition. I could proceed in fitting the new ACL bearings dry and plastigauge the crank journals to confirm the oil...

Before instructing the machine shop to remove material from the top of the block surface, I measured the 'actual' capacity of the combustion chamber in the cylinder head. This was previously original, and has only had a light skim (3 thou). 'The internet' says this should be 36cc, when in fact...

Funnily enough thinking back, the only times ive ever been taken to a weighbridge for a 'check' has been in Wales, says something that 😂 Hindsight, probably not been stopped since before any of those pictures were taken, so <2016. If you've got a shoddy looking/overloaded tow car, a shoddy...

I started towing for track days in ~2010 and thought il play the 'ill never get stopped' game. That lasted around 9 months before I got 3 points and £180 fine for it. These days, id assume its a lot more. The MAMs and limits mean nothing if you get the wrong traffic officer on a bad day...

Best mod you can do on them to be honest, transforms the car more than any power mods ever will!

Hopefully get back there at least once this year 😎

The pistons arrived a short while ago. Block has been machined to a new calculated deck height for maximum compression, bored to suit the new pistons and rings gapped. Now to assemble it 😎
