ok say i did a t4 turbo upgrade an 680cc injectors with an aftermarket fuel regulator. What kind of piggy back systems would i need to get the 1j tuned right?

A good regulator and a MSD vacuum assisted distributor will be more than enough

If you want to peak a 1jz go with a standalone such as the plug and play stinger its afordable as well.

Most people will not run a engine at peek boost hp all the time because you dont want to boost more then 15-17psi on pump gas depending on tune/managment.

Race fuel or meth I have heard up to 30psi on metal hg is possible.

I don't have an exact number or a link but I have seen around 400whp. This is with all supporting mods and more. All said and done you are running the twins well beyond what they were designed for and they will not last long. I think most people run the stock twins right around 14psi. This should net you around 300whp with supporting mods and a tune.

Like i said the stock twins can last from 5 minutes to a couple years running at stock boost or 18psi. It all depends on the condition of the twins and shear luck of the draw. If you want big power a big single is the way to go.

That would problably be me, I made 422hp at the wheels on pump gas, I believe it would not be possible to reach that high of a horsepower on stock twins with a stock ecu with a piggy back ecu.... EMS my friend, get it, get it tuned then comeback.
