I'd agree with the other fella's on the upgrades.
1) Gauges - Pyro,Tach,Boost (30psi min. )
2) Exhaust (I think 3" mandrel bent is good, 4" is perfect. )
3) Time Pump/Adjust
4) Injectors (they are 180HP marine application injectors for our year)
5) I suggest the 14cm wastegated housing. (I'd go that route next time instead of 16cm)
6) transmission temp guage if Auto trans.
7) DTT TC and VB kit. (I'm getting mine as soon as I can rob the sweety's purse)
MHO.
