Holset turbo(inturnal or exturnal BOV which is better? which holset would be good for 400hp?)
boost controller?
larger injectors(how large)/fuel pump
port and polish(head, intake and manafold)
Intercooler
e6 manafold
3in exaust
what size TB would be good to go with this?
Best i could think of just dont know what sizes would be good.
1:the Holset is a good (cheap) pick and will flow over 400 rwhp.
2:larger injectors ive usualy around 72pph , though i think u could squeeze 400 with those dodge 52's.
3: porting the head is as easy as you make it, follow the tips and guides found here and on turboford, it'll be fine.
4:3in exhuast, good.
5:t/b , seen it done on both the stock and a 65mm (supercoupe?) ones from the junkyard...its an "ok" step, will make things easier later on.
6:ranger cam
you need something higher lift, esslinger sells some roller cams that will work with the roller rockers you may have already from the ranger setup.
7: e6, yes it can be done on an e6, but a header of any sort will easily boost your ability to reach that 400hp. Results on stinger's and Rod, Bob's are 20-30rwhp...so you can see how its a major "cheap" step closer.
8: your gonna need engine management of some sort, either a tuner with a tunable ECU, or a standalone. The later is recomended as its only a few hundred bux more than a tuner setup and blows the tuner outa the water.
Or you can be like 351w , build a 300hp motor and spray it 400 which its cheaper, and nitrous on a turbo aplication is double bonus. Seen people spray 50/75hp shots and gain over 140rwhp.
