I placed this in Forced Induction but got no response so perhaps some one here can help. My friend has a 93 Del Sol with 95 GSR swap. He is building the bottom end of the engine with Eagle rods, JG Pistons, ect..... for a Drag Gen 3 turbo. He has a question about what size TB(aftermarket) to use, injectors size. What other recommendations do you guys have as in parts, fuel pressure, ect.....any help is appreciated.

I would go with 68mm tb, walbro fuel pump... the injectors and what not should be left up to the tuner IMHO. I've seen too many cases where someone got massive inj. just to have the tuner lean them out... why go through all that hassel? Talk with your tuner and see what he is planning for the car. What management system are you using Hondata?

 

as far as what we used, gsr block, sleeved, arias pistons, eagle rods, stock intake manifold and tb. 440cc injectors, vortech fmu 12:1 disk, 255lph intank pump, safc. Car pushed 326 to the wheels on 10psi.
