ive searched and read through afew different threads but couldnt find the info im after.

on my old r32 i put an rb25 turbo on my rb20 and just drilled and put a tap on the front housing.

now im going to put my spare rb25 turbo i got laying around on my rb20 in my current r32.

just wondering how else others have ran there boost lines with out having to use the r33 boost solenoid or boost controller on their rb20's.

thanks

haha left that part out , how else have they been installed with out drilling the front housing and adding a tap like i did the first time i did it.

is there a way to install them with out having to do it like i previously did , and can it be done with out using the r33 boost solenoid or a boost controller.

You either need to to drill and tap the housing or weld on a tapping point on the hot side intercooler pipe (preferably at the turbo outlet end of the pipe). Not really any other option than to source a boost reference from there. Don't listen to anyone who tells you to get it off the plenum.

Yes it can be done without any boost controller at all - just run a hose direct from boost reference location to actuator**. You will get whatever the R33 actuator is set to give (5 or 7 psi). If you want more, then you either need some sort of boost controller or you need an R32 actuator (which will give you ~10 psi). The R33 solenoid will do you no good on an R32 as the ECU doesn't know what to do with it.

**this is exactly how my Neo25 is set up at the moment in R32 until I get it inspected and can put the boost controller back on.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
