the torque is designed to bring the bolt to the elastic limit - basically you will only receive a specific amount of clamping force before the bolt starts to stretch. Toyotas engineers designed it so that the bolt does that at 25 ft/lbs +180 degrees....
How do you know that the torque is...
well I plan on using two lines - not just one. Since the stocker line (singular) has been proven to support 500 hp then I dont see why two lines (plural) couldnt easily support an 800hp (peak) setup. I havent seen people getting a new fuel line for their 400 hp setup or even 500 hp setup. On a...
I think you were looking at the 2jzGTE not the 2jzge. Im talking about using the 2jzGE and going NAT with it. MUCH CHEAPER and its nearly identical to the GTE block. Look at my build thread and the links posted in the first post. Anything and everything you want to know about it is right there.
Well the pumps arent going to "fight" each other. Pressure is pressure. As long as the excess fuel is able to feed back into the tank it doesnt matter if I have 2 3 or 4 pumps.
I have seen the other threads with other people's setups - not that they dont work or are ineffective but it isnt...
So hear me out on this one:
Being that the stock lines have been proven to support 500 hp, I am planning on going with some slight modifications to the stock lines to run a dual-feed fuel rail on my NA-T 2jz. If one line can support 500+, then it only makes sense that 2 could support 1000...
Maybe in some of the V8s and stuff the clearances are set bigger and the motor is built loose, but if you do it in this car you are asking for disaster.
There isnt any reason to make larger clearances -

I would bet on a head gasket before a cracked head. You could spend a day or two on it and throw in a Cometic.... It will probably fix the problem. Its not like you can drive it now anyway.
Sounds like its toast. Any other loose pieces? Perhaps you could fit a one-piece in there now. Steel? Any driveline shop should be able to do that for you. Carrier bearings are expensive.
I dont think this is true - people just talk about the exhaust cams because they have the gears in them to drive the CPS/Distributor. They are harder to find
So to answer the original question, I dont think any exhaust is "too big" for your goals. You will see gains that diminish as you get larger and larger. It comes down to the factors you are willing to live with:
1. Cost of materials.
2. Proximity of exhaust system to ground.
3. Difficulty...
