Yep text bar has been f*cked for a while now!

Anyway, I am no expert either but any info helps mate so cheers for the pics. Dave told me to flow the top side where the writing (106) is in the turbo pic I attached earlier.

I have ported a few RC nitro engines and they are delicate being of alloy, copper and Brass construction, cranks are steel though so this is just on a large scale I guess!

Thanks again

I lookd at you earlier post before I ported the housing. I decided to port it similar to a head. I felt that smooting all sides will increase flow and minimise turbulence in the housing and wastegate.... I will fit it in the next few weeks.. So I guess that I will soon find out if it works correctly....

Can anyone tell me who sells new studs and posi locks???

Yeah Dave told me to smooth that side I mentioned only as its the side that flows into the flapper and the flat side below would catch the exhaust gas and direct it also.

I cant see it hurting though to port both sides and may reduce the wastegate creep due to less turbulance as you mentioned.

Looks good either way though :beerchug:
