So I just picked up a slightly used Pfab Twinscroll GT35R kit and I have an 08 s2000 CR. I was talking to my tuner and they suggested I purchase the inlinepro kit to make my car convert from returnless to return type fuel system.. Is there any way around this? I have never boosted a s2000 before, but I am fairly fimiliar with turbocharged vehicles. I am not to fimiliar with the returnless fuel system and from the searches I did on here, it seems to have limitations when it comes to boost. I budgeted for the injectors and fuel pump, but not the price of the kit. So if someone has the time to explain the safe HP limits of the returnless system that would be great.

 

you can get near 500 whp without converting

 

As long as you have walbro and ID1000 injectors

But its kind of a waste to not go big with a twin scroll setup
Something to get in the future

 

does anybody know the limit of the dbw fuel set up.. if i remembered correctly the 06+ didnt need a fuel pump for anything under 500wheel with injectors

 

It depends on what type of fuel you are running. You will need atleast a walbro. I have the kit on my 07 and its a fun install lol.

My car is not up and running yet so no numbers yet.

 

near 500 w id1000s and walbro, maybe 350 w stock fuel pump? idk that anyone has pushed stock fuel pump

 

Most I made was 482 with stock fuel system maxed out. (No return)

(1,000cc + 255lph is required)

 

any complications?

 

380hp here using ID725 + stock fuel. No issues and not maxed out but I haven't checked the duty cycle.

 

we've tested both oem pump and walbro on dbw systems w id1000s and our turbo kit. stock pump is good for over 425 whp given a good turbo setup. walbro will be good for close to 500ish.
