Injector selection for tbss intake
 

Hey guys I'm pretty new to building ls motors but I'm piecing one together now. I need clarification on what style injector goes with the intake I picked up. It's the tbss intake do I need ev1 or ev6? I was looking at the 8.1 marine injectors it seems those will work but not sure. The motor is an ls1 longblock now. Wanting around 450 to 475 whp. So I think I need around 42# hr injectors right? Thanks for any help

EV1 vs EV6 depends on what type of engine harness you are using. That being said you can always use EV1 to EV6 harness adapters to use the newer EV6 injectors with older EV1 style harness connections. For your hp goals, 42# injectors seem like overkill. If you have bigger plans for more HP down the road then it won't hurt to use the 42's now.

Oh ok thanks I got 42 from a a injector size calculator online. Which injectors should I go with in your opinion?

Fast LS2 length 32# injectors for the TBSS should get you there and will not be overkill for your plan as it is for the moment. Lots of available data for tuning as well. Should be good for 500hp.

I will also credit Alvin at PCMofNC for his suggestions on these thoughts and also a sponsor here....Great group of guys to deal with!!

Awesome!!! Thanks man
