High iv just purchased an RX7 which has been modded, so far the CAT has been removed, HKS induction Kit, Front Mounted intercooler, Non sequential Turbos and an APEXi control unit, though im unaware if the car has been correctly tuned as its running rather rich?
Anyway i was told that if corretly tuned i could be producing 300-350BHP at 10PSI Boost at what point do i need to upgrade the fuel system to handle higher boost or are the other factors that need consideration too

Many thanks if you can help me out

 

iv just seen one of the post's below and it shows a video of a rx7 knocking im slightly worried now as i think mine is makin th same noises

 

I will try and help you with my limited knowledge of FDs (I assume you have an FD as you are running dual turbos). AFAIK the stock FD fuel pump is fine for the boost you are running, and as far as injectors, I haven't the slightest.

I say this because the FD pump is considered an upgrade for us FC guys. As far as your car knocking, what octane fuel are you running? I wouldn't run anything lower than 93 in a turbo car.

 

Thanks for replying

Well I’m running UK Unleaded Fuel, which I had been told buy original owner would be ok

The reason why i have the concern about the knocking is that i have FC commander and allows you to monitor sensors one of which is knock

The value given on the FC display is 0 to 100 and under acceleration reaches 32 (i have no idea what that equates to) but i would guess not good LOL I do hope I aint been sold a dud though it does go like a rocket

Does any one know what the oil pressure should read on the standard dials during idle?

Cheers
