Tuboing a car means lots of hidden costs, to name a few.

These are what i'm getting.

MSD 6BTM Ignition
RC 310cc injectors
Apex-i AVC-R boost controller
ACT clutch Stage 1
Air/fuel & Exhaust temp gauges, already have my boost guage.
etc..............

So as you can see, to make the car reliable you need a few extra things.

BTW: I have a B18B, 95' RS
