Cosmic73 Posted December 18, 2023 Author Share Posted December 18, 2023 One advantage of working for an engineering firm is that I can use the gauge lab facilities to measure my block and pistons with real hitec equipment. Considering all bores are stamped as grade 2 on the block, they've all stayed at grade 2 except cyl 6 which opened up to grade 3, however very little taper on them all. Pistons were also all grade 2 and remain grade 2 so happy days. 3 Quote Link to comment Share on other sites More sharing options...
davey_83 Posted December 20, 2023 Share Posted December 20, 2023 That's great news then at least. Fabulous work, keep it going Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted January 20 Author Share Posted January 20 Managed to sourced a refurbished revup crankshaft and bearings from Conceptua tuning. The runouts and diameters are spot on which was a relief. So, the rebuild has officially begun. Below is the fitted crank and mains ladder. I should have a set of Wiseco pistons arriving next week, 95.5mm with 11:1CR so fitting them is the next job. 3 Quote Link to comment Share on other sites More sharing options...

davey_83 Posted January 26 Share Posted January 26 Very nice, while your there I'd recommend a freshener for the steering rubber bushes https://www.torqen.uk/nissan/350z/suspension-steering/bushes/772-350z-energy-suspension-power-steering-rack-pinion-bushings.html Quote Link to comment Share on other sites More sharing options...

Cosmic73 Posted January 28 Author Share Posted January 28 Just had a very near miss while fitting my new Wisceco pistons. All going well but when fitting the end cap on piston 5, it didn't feel right and took ages to bite. Crank totally locked so after removing the cap, I realised the bearing had turned a little and got crushed. Total schoolboy error as I thought I checked it first but obviously I didn't. Luckily, the crank isn't marked but I need a new oversized .25mm rod bearing to replace, if anyone has a spare lying around? Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted February 3 Author Share Posted February 3 Fitted all my shiney new Wiseco pistons and everything's turning nice and sweet. After being badly let down by a certain supplier, ive found a superb one who really does deliver the goods. Back on track at last. 2 Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted February 8 Author Share Posted February 8 Refitting the engine back into the transmission was a pain as it just wouldn't slot and kept jamming. I used slider studs and everything, had it all lined up but no luck. Pulled it back, lubed up the gearbox shaft and it slotted straight in! Happy days 🙂 4 Quote Link to comment Share on other sites More sharing options...

Nice skills BTW, I wish I could tackle such work. It's actually not that difficult. Yes, it's complex, but the Nissan workshop manual is excellent and very clearly laid out. So really, it's just a case of having the right tools and going through each paragraph 1 step at a time. The only difficulty was being let down by a cr#p supplier.

Cosmic73 Posted February 14 Author Share Posted February 14 (edited) This evening the secondary chains and sprockets have been fitted. Also, comparing my old primary chain against the new, there's very little wear, maybe a mm or 2, so not bad for 140k miles Edited February 14 by Cosmic73 1 Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted February 15 Author Share Posted February 15 This evening I fitted the primary chain and tensioners. Does this red clip need pulling out? Quote Link to comment Share on other sites More sharing options...

What confused me was it also came with a pin fitted into the small hole which I already pulled out, believing that was the release method. Obviously must have 2 release methods in this tensioner for some reason. 1 Quote Link to comment Share on other sites More sharing options...
Cosmic73 Posted February 17 Author Share Posted February 17 Tried to fit the timing cover yesterday and it just wasn't happening. Trying to line up the dowels squeezes the rubber crescent seal out the housing. I'm going to press out the dowel pins and see if goes in any easier.
