ok, first off, ive searched on this forum and other 240 forums and found nothing on this subject. Hopefully someone can help me.

I just bought a mbc from turbonetics. its the one where you can control from the dash. I called turbonetics and they say that these mbcs are designed for dual port wastegate actuators. Well as you know, the sr20det has single port. Is there any way around this? There is 1 inlet and 1 outlet in this mbc. 1st one is for boost line, 2nd is for vaccum to the 2nd port on the wastegate actuator. instead of hooking the 2nd port to the vaccum (since its only single port) i hooked it up to my intake (another website said to do this). I dont know if this is safe or what. It seems like it works great. Any suggestions? Thanks for the help in advance guys. Oh yeah. does the s14 sr20det have a stock boost controler? reason is, there is a valve looking object that the wastegate boost line goes to. then out of the valve, the line goes to intake. I hooked up the boost control after this valve thingy. What is that thing? i couldnt find it anywhere on the forums. Thanks.

 

It was probably designed for the FD to help regulate boost on the seq. twins, I belive there may be a way around it try caping one of each of the vac lines one from the chargepipe, and one to the actuator. That should leave you a total of two vaccum lines that are not capped

 

can you go into more detail? sorry im a noob
