Hi ,

Can anybody tell me if the wastegate port and penny are bigger on the P20 exhaust housing compared to a P18 housing ???
If so can a P20 housing be fitted to a VF28 ??

Thanks .

Both the same, and the P18/P20 should be swappable. It's always worth checking the exhaust wheel for clearance, incase there are any manufacturing tolerance issues.

if i remember correctly
p20 on a vf28 should make a vf23

I'm sure that's what i have running on mine

So what is the difference between the housings ?
I have already had the P18 housing ported but still suffer from boost creep on my 2.5 , Would ther be any benefit from fitting a ported P20 housing ??

cheers

When you say ported, where on the housing has it been ported ? A P20 will help a bit, but I would expect that to need correctly porting too.

If you disconnect the actuator hose, do you still get boost creep ?

Hi Mark ,
How have you been , long time no speak !!
The waste gate exit port and housing inlet has been matched to the up-pipe and was done by TweenieRob , forgot to say it is a VF 28 in case you hadn't guessed .
Have to try it without the actuator connected yet , using a Dawes device for boost control at the mo !!

Mike, BMW mike ?

try without the hose, and let me know if it works. May need some more porting.

Also, been meaning to get hold of you ! Will speak soon.
