I recently bought svo 30lb injectors(36lb) for my set up I got full bolt ons will be running stock heads and I'm about to switch out my cam for the t-Rex and have a 150 shot through direct port on my fast 90/90 should I stick with these or buy the gtp 36lb which I believe flow at 41lb if I'm not mistaken or even go for 42lb injectors I got the walbro fuel pump ready and my fast fuel rails also just wanted to do it once and do it right

Thanks

 

If you are planning a wet shot then injectors do not matter. Just go with whatever size injector you need for your motor.

 

as stated up top, injector size only matters on the dry kits.

 

Ok thanks for the tip guys appreciate it

 

As mentioned before, if you are going a wet system you can only choose what's enough for your N/A power ..

Anyway, select the injectors that your tuner have all the data for them, for example .. SVO 30lb or 42lb are good upgrade since tuners can find the required data that help drivability alot while in other hand FAST 36lb injectors data cannot be find .. which in bigger cams you may have drivability issues due to lack of injectors tune

 

If you go with the TREX cam when you start retuning the car just keep and eye on the injector duty cycle. We just tuned a vette stock ls1 with 5.3 heads from texas speed and ms3 cam the guy just had stock injectors and it maxed them ou at half throttle. 36lb injectors should be fine. Or just get the 42lb green tops.
I would change what you want to change on your car (fuel pump,rails,cam) before you get your tune done. You need anything hollar.

 

Yea I was planning on all that done and went crazy on buying nitrous parts from nitrous outlet Christmas came early for me Haha dnkynrbk your car looks savage in that pic 9 seconds you make mine seem like a Honda Haha one day I'll hit that time

 

Man a TRex with stock heads is going to have a close PTV. Thunder Racing told me .020-.040 clearance. I sent it back and got the RapTR for a little more safety margin...
