I understand the 99vr-4 is considerably more difficult to modify than earlier cars.

I assume downpipe, exhaust, boost controler, air intake will not create problems.......but that injectors, bigger turbos and associated modifications
are much more difficult to set up properly than on a 91,92,93 vr-4.

Is this true and can these modifications be installed in such a way as to overcome these difficulties ?

All of the 96+ 3S's carry the same differances. Tuning for fuel is different but not harder. If you check out the ECU Tuning forum you should find all of the information you might need.

Alan is right about the 96+ of course. The reason is the dreaded OBDII diagnostic system.

OBDI FTW!
