Castrol Edge 25W50 http://www.castrol.com/en_au/australia/car-engine-oil/engine-oil-viscosity/25w-50.html

Hi Matt, No, the P90 is not welded or heavily skimmed. As you probably know P90's have a deeper chamber (ports are higher in the head too), so to get the compression up, you have to run a raised crown / 'lumpy top' piston. The raised crown also promotes better cylinder burn - as long as the...

Yes we do :devil: The crux of it was that I wasn't going to warranty it for any serious competition use. If it had a billet crank - no problem...

Hi Alan, No, I am not offended. You do indeed have a valid point - I was unsure of what the UK market thought of my short engine, however I now - after reading this thread - have a clearer picture. Indeed, I was not selling the short engine as something that one could slap a P90 on with a...

It always irks me when people refer to Rebello as the 'standard' for performance L series builds, as people always accept claims as gospel without bothering to understand what they are ACTUALLY looking at. Les has a couple of sayings: 1. "People don't move outside their 'clan/tribe' ", to...

I know you didn't Matt - and I wasn't applying a negative tone. I was just stating general facts & trying to understand the situation in the UK. The general consensus I get is that the exchange rate is the issue (you silly fools shouldn't have voted for Brexit! :p ), so hopefully the economy...

Apart from yourself Matt, I had another UK member interested in buying it. I was willing to help as much I could with the sale receipt & finding the best price for freight, however it's apparently still an expensive process for a UK buyer even with the exchange rate the way it is ATM...

It's staying in Australia, Sean.

Sold.

Indeed. I bought 4 complete L28 engines (@ AUS$500 a pop) to get this one block that would take a 89mm bore...

Due to the mounting offset on the crank, they can't be made any lighter.

For Sale: L28 3.3ltr short engine. 89mm bore x 89mm stoke = 3322cc Engineered by Les Collins Racing. Built by myself under his direct guidance. F54 block. Acid dipped, 1/2 grout fill, sonic tested & offset bored to 89mm, & finial Diamond honed to exact clearance. Deck milled parallel...

You need to put your finger in the hole in the shifter striker rod, so you can move it to make the finger move out of the fork ends. Then you can remove the housing. What's happened is somehow you've selected 2 gears in the gearbox - they why it's locked up. It can happen & I suggest you...

Oil wont have anything to do with the 'crunching' when downshifting to 2nd. What model gearbox is it? If it's a late 240Z or 260Z 71B unit, it'll be a Steel 'Bulk Ring' type syncromesh. 2nd & 3rd in these gearbox's cop the most abuse, and I'd say when the box has been rebuilt, they did not...

And that's the rub: 'Performance isn't Cheap. How fast do you want to go?'

Cost for a complete engine, dyno tuned & ready to install in a Z is around AUS$26,000 The 'VVTI' comment Jeff made in the thread is incorrect. The rods are indeed off-the-shelf I-Beam items with 137mm centres that are commonly available, and fit variety of engines.

I'm unsure if it will be strapped to a chassis dyno (rolling road) - more likely it'll be road tuned to check Lamda if required. I asked Les & he said from experience it'd make 'around' 180rwKW on a Dyno Dynamics chassis dyno.

No, we have 98RON octane fuel easily available here. What makes you say it's a low static CR? Static CR is at 10.5:1 so it could have plenty of timing added if required. Les hasn't found any need to go above 11:1 on L-series engines on 98 pump fuel as they don't make any more power/torque.

My engine builder here in Australia - Les Collins Racing - has just finished this L24 for another customer. The brief from the client was to use the original matching numbers L24 engine (P30 block & E88 head) from his 240Z (that he is restoring), fuel inject it & get some more performance out...

Put an ATI on it: http://www.summitracing.com/int/parts/ati-918040/overview/ & use a RB25 crank bolt.
