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...

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.

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. Because 4-cycle engines contain two and three rings, the end gaps do require different valu...

A couple of pictures showing the areas that require clearancing. You can tell if it is a late block, as there will be bulges on the outside on the exhaust side where my second pic shows the clearancing for the rod bolts.

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...

45's are not too big, with my cam (higher rpm) I need 48's. We need your complete set up, at the very minimum please provide the following: Choke size: Emulsion tube: Main jets: Main air correctors: Primary (idle) jets: Primary correctors: Once you get me these details I will check it against my tun...

Can you post a picture where it is touching, trying to picture how it might do that.

[/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...

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...
