KA-T build questions....? Looking for good ideas on KA-T ....

[uvamosk]

Hey, Im building a KA-T I have bought a T3/T4 turbo with a .70 trim. I have Jim Wolf ecu made for 50lbs injecters. IM wanting to hit at lest 400hp at the wheel. Here is the list as follows for the engine build wanting to input on what else i should buy...

T3/T4 turbo .70 trimJim wolf ecu,Walbro Fuel pump,38mm Waste gate,Crower rods,Wiseco Pistons, 9:1 comp bored .20 overFerrea Valves, Stock Nissian Springs, Stock Nissian Retainers,3angle valve job,1mm over valves,Custom Made Intake Plenulem <-- isnt spelled right... ( The part the TB is hooked to, Made it to have short runners... and got rid of that horrific spiral)Cast iron Manifold for the turbo with center waste gate postion.3in Exhaust from turbine out let back no cat. Safc IIMetal HeadgasketAlum RadaitorTop fead injecters and fuel rail setup with ADJ fuel regulator.

I wanting to know if I should bother Knifeing the crank or not ? I was going to get SS valve springs and titanium retainers but figured they wouldnt be worth the money seeing as the engine isnt going to see High revs above stock... I dont see how spending 800$ on springs and retainers is going to add any hp.. SS valves I could see the benifet becuase they are going to see high COMP pressure and Heat.

I was told by someone that i would probably need to run 75lbs injecters? Im going to Dyno it and let them help me tune the SAFC and Fuel pressure.

If anyone can shoot me some ideas on what i should do to better help build the engine please do so... Im wanting to hit the 400hp mark and lower the car weight down to below 2600lbs ...

Thanks

Definately gonna need injectors. Stock are tiny 270cc's.

O defently going to run 50lbs or higher but my problem is the ecu is made for 50lbs injecters and people said 75lbs is what ill need to make 400whp?

Im still trying to figure out if knifeing the crank is worth the hassle

The 50lb injectors are good to 364hp. Yes you could bump the fuel pressure, or make them open sooner etc. But why risk it. Get a part that won't be stressed on.Also JWT ecu runs rich. So your goign to need to fine tune it anywayz
