@Tuned by Rabbid what a great detailed and very well explained series of videos. Thanks so much for this. Please dont delete these videos il be using or following very closely in the near future. One question though... where can i find the dimensions, tolerances & clearances of OEM internal components? I have trouble finding these for some engines. Is there a 'go to' place to get this info?

You should speak with the manufacturer for this information.

Hi, thank you for the video. you say you need to torque all the bolts (I'm assuming Torque + Angle) when measuring clearances, since the bolts stretch, are u using new bolts each time you need to perform a new measure? What about the final assembly are you using new bolts? Thank you.

You can reuse them during testing and assembly. It's more not to reuse heat cycled bolts or bolts which have been torqued for a considerable amount of time. Some people will use stretch gauges to get more accurate readings on some though

On the Z20 engines, what’s the best way to seal the rear main cap? Do you apply silicone only in the groves? Do you allow it time to go tacky before fitting the cap into the block?

It's easily a weeks labour, any quicker you're not doing it properly. But that doesn't account for machinist delays or parts delays. Or that you should go step by step order the right part and size then move onto the next step. So could easily be a couple months in real time.

How much did the whole engine build Cost?
@tunedbyrabbid
@tunedbyrabbid 3 года назад
Depends on your requirements, could be anywhere from £2,000 to £5,000 Depending on spec, the condition of the old engine, whether we'd remove and install or just do the engine etc

Hi what is the expect journal size for a z20let
@tunedbyrabbid
@tunedbyrabbid 2 года назад
Approx 50mm and 40mm I believe so you'd want clearances of 0.05mm and 0.038mm respectively

@@tunedbyrabbid thank you for the reply what are the limits for the crank as I am getting my crank at 57.8mm and I carnt find any information on what the limits are for the crank

I wouldn't grinde a crank personally so what are your clearances. Its ideally 0.05 I wouldn't go more than 0.063
