Bob said there at 96% if I remember correctly. I said about putting larger injectors in. He said he was happy with it and it was safe as I was worried.

The car also has a Boomba 75mm throttle body fitted which are supposed too give good gains

Injectors at 96 percent lol anything over 80 percent is considered risky

Depending on fuel set up 96% DC is not leaving much head room with the injectors flowing at nearly their full capacity wether bob thinks so or not! If it was me i would be advising that he would need to be seriously thinking/considering about upgrading his injector size in the near future.SJ.

I agree with Raggy some mappers wont go near to that level as it gets proper marginal on reliability.

with internal waste gate

The FP 71HTA™ turbocharger for the Subaru WRX/STI features the 71HTA™ compressor section with a 58MM stock appearing compressor cover coupled to the 8cm2 turbine section. This combo produces the fastest spool and transient response possible of any of our Subaru based turbochargers. The FP 71HTA™ flows 51LB a minute which is capable of producing upwards of 425WHP.
thats still a journal bearing turbo,surely i would be better going for a ball bearing turbo mate

couldn't recommend them enough really , very helpful considering how far away they are lol ,, turbo is still going strong without any signs of wear yet so very impressed with its results as been on the car a few years now and gets used as a daily now lol

id buy from them again without any worries ,, and would buy there intake again as it made life so much easier as it fitted without having to remove the inlet manifold ,, and thats good going for a 83mm inlet lol

yes had various quotes for replacing the rods and re-using my crank/pistons if they are within spec and have various quotes for full rebuilds.

2.35 is sounding nice now though...........
