hey.

i have had my plenum on my RB20DET modified to relocate the throttle body from the side to the front.

at the front of the plenem there used to be the coolant lines goin to it and a few others.

now where should i hook up these coolant lines? should i block em off or put a T-piece and join the three together?

them vacum for the pressure reg i presume just get from anywhere on plenum.

the oil breather one is taken care of via catch can.

ive included a few pics of my setup and a standard so you know what im on about.

any help would be great.

cheers

That 10mm bolt that isnt there anymore is used to bleed the air out of the cooling system, maybe making up a....... um how do i explain it..... water tank that the lines will run into with a cap or bleeder on top so you can still bleed the system might be the best bet.

im gussing the RB20 has the water feed through the throttle body like the R33 .. what did they do with that?

i have the plazmaman planum and there is no bleed for the radiator... just have to be patient on bleeding the radiator manualy via the turbo water feed, or the rad cap.

i got plazmaman plenum too. awesome gear!

don't forget if you block that water line off where it goes too after the throttlebody!!! it feeds your turbo!

id personally block the throttlebody off and run a fresh line to the turbo. Im getting a header tank and doing away with the bleed on mine.

You sure about this one ?? I have the line blocked off for my throttle body and the turbo still gets water. Doesnt the turbo line feed from the back of the plenum ?? and then back into the side of the block ?

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
