I don't think it is worth the time to spin balance a stock rotating assembly if it is all the same old parts being reused. If it is all new stock pistons and rods then I would. If you are reusing all the parts that came out of the block originally, then re-place them into the same location.

There is no real apples to apples comparison between shops and type of builds. Each shop has its own idea on what a performance build is and what it should cost. Choose reputation and quality of work instead of price because no price can be put on doing it right.

Moy - I have some room to work on price.

I am not familiar with the alloy Arias uses or the gram weigt of the piston. You will need to check that. The Alloy and weight of CP and JE pistons we like to do .0042 to .0045 for a race motor with nitrous. As always, you will want to be at operating temps before seeing the track or any...

They are based on the proven cam profile in the Malta Dragster, but a tamer "street/strip version" if you will. Heavy - The black is from heat treatment. It does not come off unless you grind it. That is the color of the metal.

Just wanted to post some pics of my new billet cams. Going to install a set in a head for my car later in December with some 28mm solid buckets. They are a staggered set. intake is 11.15mm lift 290 duration 246 duration at 1mm lift. the exhaust is 10.25mm 268 duration, 224 duration at 1mm of...

What pistons do you plan on using? The piston used determine the clearance as much as the end use of the piston.

Gaboon. Cometic is all one division. A good few of their full gasket kits do come with a MLS head gasket. The 7m just happens to be one that does not. Cometic does not make mot of the componants in the gasket sets. Most of the parts are sourced from other manufacturers. At least most of them are...

You should also pull the efi fuse. spraying fuel into your cylinder durning the test will give you a false higher number since fuel takes up space.

It sounds as if you purchased the pistons prior to the machinist telling you what size pistons you need to buy. Lets hope that your bores are in good enough shape that the machinist can fit std size probe pistons into the Std toyota bore. Tell the machinist that you will want a .0035 to .0038...

Get a plate that has one sde flat, and the other side with grooves cut at a 30 to 45 degree angle. the groove side will cut faster, the flat will finish better. Diamond paste is your best choice, but if none can be found, then emery flour mixed into lard works well. You thin that with...

Blitz Nu-r! Lots of people say it is too loud, I say all other exhaust are too quiet. 80mm pipe too not 75mm like most all others.

I worked at Ajax manufacturing which is a giant machine shop/tool and die shop around here, a mold shop, and a aluminum foundry, prior to turning to motor shops. Could not find anyone to properly machine our nitromethane motors, so started doing it myself years ago.

I have used pcd inserts before in the past, was not much better. In all the machine shops I have worked in, it is only the wrong tool if it does not work.

Its not hot and humid everyday....well almost, but you are so close to sea level that besides the heat and humidity, you have excellent air. Florida air is good compared to say Denver.

Cubic Boron Not for 7m head. LOL CBN insert has worked perfect for me.?. This is a single pass without lifting the cutter on the return. Single CBN cutter on a dual cutter head. RA of under 50 everytime..

For a dry sump system, you can adjust the pressure by using and external oil pressure regulator. Making a bolt on dry sump system for a mk3 with a 7m is on my to-do list for future SIP products. Don't use these fiqures for your street car, but Gary runs 85 psi of oil pressure on his dry sump...

Kai - If the head is not warped out of spec, a cut of about .0012 to .0018 is usually enough to do the job provided the fire rings from the previous gasket did not indent too much. The problem is that many machine shops will go over kill on the amount cut just to save themselves the set up time...

Yes, that is just the seam of the two outer shell halfs and that is spot where they come together. You will notice another tab on the other side. They are rototed off center like that because of the position it sits in the shaft tunnel does not allow it to be centered. Some of the really old...

If you build such a set up to spray liquid on your intercooler, and then use it at any dragstrip in the country, they will most likely kick you out and ask you not to come back for dripping liquid onto the track. The guy who runs in the same lane after you do maybe a bit upset if he wreaks his...
