Re: piston ring gap size
All those tools are great, but can be costly, depending upon your budget, rpm/hp you are expecting, time and skills you can cut that list of tools dramaticly to the following: 1, Ring grinder: a very fine file as per the link above, or I used a sharpening stone. 2, Bolt stretch gauge: this depends u...

Re: piston ring gap size
You don't need any special tools to check and adjust ring gap, you place the ring in the bore and measure with feeler gauges, I use a sharpening stone to then adjust the gap. http://www.laskeyracing.com/shop/ringgap.htm Have a read here then do a bit of a search and you will get the idea.

Re: piston ring gap size
Ring gap should be as per the piston spec sheet from Wiseco, not the toyota specs, from the Wiseco FAQ page: Wiseco 4-cycle Powersports piston rings are designed with the proper end gap for most applications.

Re: 3tc crankshaft on 2tc
Having built 3 X 2tc engines with 3t cranks, you will require the crank and the pistons as the rods are the same, block modifications will depend whether you have an early or late block, as the early blocks require clearancing on the bottom of the bore and if you are using standard rods, you will ne...

Re: Cam bearings
[/quote] It is your engine and you have the situation well in control. I have a different look at why I change them, That tool cost enough that I want to get some use out of it, plus like the idea of virgin bearing installed. Good luck with your build.[/quote] Fair enough reason, engine has been goi...

Re: 3tc dyno numbers, anybody?
How does such high comp build run on E85 ethanol with the 12 comp I have stayed well away from ethanol for then following reasons: -fuel consumption is basically doubled, so I need to carry twice the weight in fuel and the economics of running ethanol over race fuel is diminished. -corrosion and da...
