I originaly planned on getting 880cc PTE injectors, but I might be able to get a good deal on some 780cc.

My question is, for 93 pump and about 24-26 psi will 780cc be enough? this will be for a full bolt-on EVO IX. I doubt this car will ever see more then 420whp in the future.

 

It will be enough.

 

I know this isn't a real answer, but I'd ask whomever will be tuning the car. Because they will have to make whatever injectors work and I'm willing to bet some tuners would have different ideas for fuel needs for those power levels.

 

You may as well go bigger to give more scope for the future. I wished i would have just got 1000's instead of the 750's i currently run. They're usually the same price...

 

780s will max around 450-460 on gas. Honestly its the same price for 1000s and its just as easy to retune. They will support up to about 600whp on one pump on gas.

 

Thanks guys for the help and advice. I agree about the 1000cc being same price as the smaller ones. The 780cc are from someone on the forum that had them for a very good price (alot cheaper then 880cc, 1000cc), so I just decided to go with those. I know my car won't go past 400whp for the next 2 years so 780 will do.

Thanks again.

 

Sounds like you made the right choice, worst case you'll buy bigger ones down the road!
