I just got a 1984 gsl-se with the 13b-resi I know how to make the engine flow better with exhaust but I'm worried about the stock fuel system I'm only trying to make 165hp can I get bigger fuel injectors for the 13b resi

 

with just exhaust and stock ports, it should be ok. you will want to replace the fuel filters, there are two and a screen that needs cleaning. you might send out the injectors to be cleaned too.

if you still need more fuel, the AFM is adjustable, and you can probably squeeze a tad more out of it.

if you STILL needed more, i think bumping the fuel pressure a little would be the way to go,

 

I talked to the po and he said the fuel psi is up 5-6psi so I'm goin for exhaust but can I make 165hp with out larger injectors how do I adjust afm?

 

The fuel system is clean and only has 15k on pump

 

you need to put a voltmeter on it, and see what the voltage is @wot. its a 12V system, so higher voltage = more open.

so then once you know where you are, then you can look at the meter, and there is a bolt on the side that adjusts how far the door can open, and you want to adjust this so you get slightly more voltage @wot. you wont be able to make a big change, but with a little more fuel pressure, a little more injector duty, and a good pump, you should be ok

 

Thank you very much I love this car has anyone wrapped their exhaust I'm thinking about wrapping from manifold to mid pipe to help get that heat out the back and not in the car I'm worried about overheating the exhaust
