Now everything fits nicely and has enough clearance to where it won’t rub even if the engine rocks around a bit.
All of the charge piping is in place and everything looks great. If we were going to run the tuning solution that comes with the kit, we would be nearly done but we did not want to run a boost dependent fuel pressure regulator and big pump for enrichment with a piggyback spark retard box. We wanted to do something that would be more OEM like and have a lot of headspace for additional power if we decided to mod the engine further at a later date. Now note that if you start to modify the kits engine management you will lose CARB approval even if a solution like this probably has the potential for less emissions.
The stock fuel pump is way too small for the potential power we have so we installed a Deatschwerks DW300 pump. The DW300 flows a huge 340 liters per hour and drops right into the G35’s tank. The DW300 has a 3 year warranty and is E85 compatible.
We accessed the fuel pump by removing the rear seat and the pump access hatch in the floor.
The pump lives in this plastic assembly that you can just lift out of the top of the tank.
The plastic pump housing snaps apart.
The stock pump is removed from the housing.
The DW300 pump is almost identical in size to the stock pump.
