Nitrous Oxide on a 1989/90 240DL 200 1990

I am in the final stages of reassembling a 240 with the drivetrain out of an 89 240 and the body of a 240DL 1990. We purchased the 1989 new and have greatly enjoyed it until my Wife's 50 MPH accident in January. Lets just say that if she were in any other car, I would be a Widower. For example, the nose of the car was 3 feet shorter, the B pillar was pulled in and forward by the seatbelt, and there wasn't a single piece of sheetmetal that didn't have a wrinkle in it. She didn't walk away, but is recovering from a fracture in her neck (NO PARALYSIS!)

Now down to the details.... I have bored the block 0.060 over, installed larger 240Z intake valves, ported / polished the head and intake manifold, and radically reduced flow restrictions in the intake system. These changes have gotten the HP up to 150 (from 113 stock), but it still "seems" inadequite in a 4000 pound car.

My questions are as follows:

1: Has anyone strapped a NOS system to a B230F before?

2: Was it necessary to run a wet or dry system (ie. did the ECU compensate automatically?)

3: If a "dry" system was used and the ECU did not compensate, was an additional pressure fitting required for the fuel pressure regulator?

4: If a "dry" system was used, was the cold start injector or additional injector(s)used to "in effect" create a "wet" system?

In closing, I am not looking to create a drag car. I am only interested in getting the HP over 200 for "merging"/"emergency" situations. Please also note that this "project" started as a "let's create reliable transportation", it has now "GROWN" to be a true restoration with performance modifications only. Can you say "SLEEPER"... I knew you could! The exterior is being maintained at a "Rock Stock" level.Honest Officer... I am a Physics Professor driving an extremely safe lead Brick.... Your Radar Gun must have been "confused" by a secondary sub-90 degree Doppler Reflection off of the surrounding vehicles! If you are interested, I can share my Ancestral Doughnut recipes with you!

Thank you,
John Orrell
