im stuck on these fittings that have a -AN, im using a walbro inline which has a 10mm thread. what -AN is that and do i just go bigger hose soo i get the volume.

thanks

 

-6 an will be suffcient for your application. You will need a 10mm adapter to -6an fitting to run out of the walbro. Any an fitting manufacter will sell metric adapters.

 

are you sure about my application, B20 stroker with B16a head, getting a GT3788R. is that still suffiecient for my application

 

Well in that case what is your hp goal and what else does the rest of your fuel system consist of?

 

man, the stock lines are good for about 450-500whp, I wouldn't have replaced them and just used an in-tank walbro.....but thats just me.

 

well i dunno wut am gonna be making, thats your job to find out andrew lol, prob in may you will be taking my car for a tune. im hoping for around 500 or more.

 

agreed for sure but based on the turbo size i am thinking he wants to go beyond that.

The gt3788r is rated from garrett for 440-675hp but they rate strictly on exducer size not actual maximum output.

 

What does your fuel system consist of?

 

soo far a walbro inline pump, braided fuel lines, not sure what size they put in. i have 455cc injectore i think but i relly need bigger ones. those i got in the kit when purchasing the turbo which now is a turbonetics t3/t4. i only mentioned the garrett because i want a bigger one

 

for 500whp you'll definately need larger than 450cc injectors, they typically only support 300-325whp.

 

What fuel pump is in tank? Those injectors are definatly too small if your looking for a 500+whp car. Is this a pump gas street car?

For the fuel system i would do an intank walbro and external bosch 044 or external walbro and intank walbro. This will ensure enough fueling capabilities if your looking to push the car beyond 500hp. I would also rewire both fuel pumps so you do not get any voltage drop occuring.
external fuel pumps tend to be very loud so i would definatly recommend mounting at the rear of the car with a the rubber sleeve around the pump to dampen the noise.

The reason i asked if it was a street car is because as zeeman said you can get away with stock lines and a hp walbro. You will also be on the verge of needed high octane fuel in order to supress the potential detonation that will occur. If staying on pump gas you will be under 500whp and the single hp walbro will do and i would ditch the external walbro for noise/comfort level. I do however still recommend the fuel pump rewire.

 

well this whole project started when i did the fuel system, my stock tank had a leak soo i got this crazy idea to make a drag/street car. soo in the fuel cell she went which uses a external pump. but til the motor is in i dunt kno what she needs or what to change. thats what andrew n your hi velocity tuning magic will tell me. oh by the way can you solder in my hondata chip into my ecu, im worried about to much heat on the circuits

 

The fuel cell should be baffled or blattered. The fuel pump should be mounted lower then the fuel cell to reduce cavitation which can lean out the engine and reduce fuel pump life. Basically there are a few options you can do but it is directly related to what power the car is going to make or what you want to make on either pump gas or race gas.

 

ok sounds good, thanks for the advice. but she wunt be ready till prob may, ran out of money. need crank, rods and pistons plus few other small parts. its a slow working progress thats for sure
