is it 160-170 BHP (crank), or WHP?
For 160-170 WHP you probably need 310cc
If you mean at the crank, you'll only need in the upper 200's. I'd just get 310cc though to leave room for future upgrading such as a built block and a 75 shot or something.


Wait a second though. If you get the ZEX wet kit i'm recommending, you don't need new injectors OR a tune. It comes with a computer box that automatically adds the right amount of fuel. You only need to upgrade injectors with a dry kit.

A wet kit adds the fuel in with the NO2 before it comes out the jet and into the intake. A dry kit adds just nitrous and you must supply extra fuel yourself.

 

Correction a dry kit sprays just nitrious and adds more fuel by increaseing fuel pressure with pressure fron the nitrious kit. But wet is the way to go for spray. I will be going turbo though insted of spray. I want the power there all the time not just when the bottle is on. I was thing 160-170bhp unless you feel I could make 160-170whp. Would the stock injectors due for a short time on low boost with a tune of coarse??

 

With a turbo you could make 200WHP on that engine as long as it's in good condition.
With 160-170WHP, i'd imagine stock injectors will be fine, however I would get 330cc injectors.

 

Wow 200hp no kidding. Yeah the motor is in great shape stronge and healthy.

 

For 200WHP you should get 440-450cc injectors.

 

What injectors would you suggest brand wise. I know RC injectors are good but I dont want to spend $300 on them. Any other injectors that will swap onto my stock fuel rail? I know some people use DSM injectors from turbo and non turbo eclispes. How is this swap done?

 

Precision injectors from Phearable.net are a great value and are quality injectors.

About the RC's though... get on hondamarketplace.com and look for some. I bought 440cc RC injectors for $150, and the guy I bought them from only used them for 2 dyno runs and then realized the fuel flow rate wasn't high enough for his setup.

DSM injectors can be used. Though, you'll need a resistor box to be able to run the low impedance injectors on your car because your car uses high impedance (a.k.a. saturated) injectors.

 

rx7 injectors theyre saturated

 

What year and spec rx7 turbo nonturbo twin turbo? and do they fit on the stock intake mani and fuel fail?? I think that 440-450ccs will be overkill for my needs. For 200whp 300cc should be more than enough and I only want like 170whp.

 

i'd search for you on homemadeturbo but i got banned lol =[
f you are considering the turbo route hit up homemadeturbo.com its a shadow of what it used to be but most of the tech is still there until it gets pulled sooner or later. just search you can ask but i can almost guarantee your question wont be answered the og's are gone.
