cup mod

[mgree10]

please help me decide,is it a modification i want to carry out,does it improve turbo response?does it affect hot/cold weather starting?cheers....mark

I just do it to tidy up the engine bay.

Performance wise i can't tell, i know i had to adjust the actuator again when i did it though.

yeh i agree with ash it does make it tidier and also by blocking of the the breather to the inlet on the turbo it stops any dirty, oily stuff going in there. but this can be doin with out doin the cup mod

i done this,

drove about for a mile

then proptly took it off

im running 14psi with the acuater arm screwed in,

it made less boost and didnt come on so quickly plus it didnt hold boost, made the car splutter down low

tbh i dont see what the rve is all about,

the only thing i can think of is if this mod requires a acuater with one port



tho try it your self see what u think it may be better maybe not.
you can use your exsiting pipe run to do this, just use a few bolts and jubile cips as a temp while you test it out

If you remove all the little bits carefully without cutting through any ill buy them off you! I want to go OE!

tremendous feedback...can i say that since using the website forums ive recieved the help and guidance ive always needed...a huge thanks to you all...and watch out for my little five and me on the website more and more,im probably going to use the origional twin port t2 actuator...cheers again mark.

no probs mate, thats what these forums are set up to do. good luck tho mate


also just a note, dont bother with boost controlers unless there well made (expencive ones) or a electronic ones,

or to agjust boost turn the actuater arm clockwise tp increase boost

[rs250nut]

Dont just go winding up the boost with with no extra fuel

14psi is fine on standard fueling after that yes bigger jets are needed

basicly its suppose to improve the respone of the acuater meaning it will hold boost better, but i found the psi was down and infact didnt hold boost as well and infact the boost was all over the place

wot u have to take into account wen saying things like this  is, 14psi  top of carb the oe jets are fine but 14psi below the carb is a different story

[r5gttraider]

well yes but then it depends were were all talking about, at the i/c top of carb or below. im just talking in genreal on the stock turbo gaudge, which is taken from were?
