I have just purchased a 2000 Pontiac Bonneville SSEI. I am about to make the following performance mods to start with more to follow. Any suggestions or experiences with these mods would be helpful.

First is a MAP Engineering Intercooler system to help get the best and safest gains from a 3.0 pulley.

Then a set of "Other guys" headers, to a map engineering high flow catalytic converter that eliminates the u-bend, then to dual Aero-turbine mufflers.

Reprogram the computer eliminating the speed limiter and optimizing the mods performance

A ZEX 75hp wetshot nitrous system

Could someone suggest a trans oil cooler to help it handle the power?

There are more mods planned for the future, this is just first wave of the performance mods, also big plans for A/V, interior, and styling. Thanks for your help.

You may want to go with SLP headers since I don't think TOG is in business anymore..
And unlike the w-body cars our h-body cars don't have a u-bend.

Their are alot of Bonne'* out their with even more extreme mods them that. All I have to say is do your research before you buy something then later find out that it'* junk. Your best bet is to talk with ZZPerformance or INTENSE Racing about what your goals are and they will set you up.

I would look into mods for your transmission too.
That kind of power is sure to take out that stock 4T65-E..
shift kit?

You might want to research running N20 with an intercooler. I have heard conflicting stories on the pros and cons. But you would have a helluva low IAT

Click my mod list. An intercooler is probably one of the last things I would do to be honest.

Or you could skip the intercooler and use the nitrous for intercooling during races. I don't know much about anything though.
