for my swap into my 72 Datsun i bought a vibrant 3" inlet muffler with a 4" tip, and the motor is a stock TII with a 3" down pipe, on the down pipe is a cherry bomb for a resonator not sure if I'm going to use the cherry bomb or not. the rest of the exhaust will be 3". will this cause any problems? i was told something about it starving for fuel or over boost at hight rpm's?

 

it will cause ears to hurt, lots of vibration within the car, and set off a lot of car alarms

good choice

 

It will open up a lot of flow to the turbo, more than the wastegate will be able to control. It will want to keep building boost, until the fuel cut kicks in.

You will need a fuel cut defender, and ideally some bigger secondary injectors to handle the raised boost.

 

ya i think I'm going to get a vibrant ultra quiet 3" resonator.

 

ok well my fuel pump in the rx7 tank will not work in the 510 so i think i need a new pump that i can put in line, on my frame so i can use my stock tank. what pump is good for this? will this solve the problem?
