What's up Honda tech. I'm new to this. I'm currently about to start my b20 vtec turbo build. I have a low compression b20 block with a b16 head. I have a full eBay turbo kit. I also have skunk2 stage 2 cams. I'm planning on using a hondata s300 ecu for it. What else do I need? I'm looking to shoot for at least 300hp. What else do I need to achieve this with out blowing the motor? Any guidance would help! Thank you!!

 

Talkin' about electronics, you should need to buy a 3 bar map sensor and bigger injectors (550cc/min would be fine for 300HP). Oh, and for sure, an ECU to plug the S300 module on it

 

What ecu would be ideal for an s300?

 

P28 would be fine (any Honda OBD1 VTEC ecu should work, also non-vtec converted ones)
