Ok, which do y'all think will help flow air through the turbo better? POrting and polishing, or the jet coating of it? Could you also if possible include the reasons why?

Thanks loads!

BOTH...

Jet coating won't help flow into the turbo, however it will help by keeping heat (and therefore more expanding gases) in the exhaust manifold, Turbine housing, and O2 housing.

Porting/polishing will remove sharp edges and increase slightly the size of the passages the gases travel through.

On a side note, the real restriction in this is the turbo impeller itself, the nozzle, and the wastegate port itself, those things you don't typically need to alter on a stock turbo (if you could, and you did, you'd alter the spool of the turbo and not the peak power it can make, in most cases the side effects would be undesirable) however this is why the 10.5 hot side replacement has also been a popular mod and should be on your list if your already planning on removing parts to port/polish/coat them..

The combination of the two will provide a marked improvement in performance. Overall its worth a few horsepower, but the peak numbers don't really tell the story, the story is the slightly better throttle response, spool, and a slightly broader torque curve which makes the car feel more responsive.

yeah buschur offers the Polishing and Jet coating on the stock exhaust manifold and also the 02 housing, though exchange policy.

I was considering this since the stock exhaust manifold looks like crap currently anyway.

wouldnt it be better to ceramic coat the o2 housing? cuz i know the helix will crack if u dont =)

I'm gettin a full turboback from RNR with a 02 housing, should I get that coated before getting it installed?

if so, ceramic? or jet hot?

Just coat the downpipe on the exhaust. Also coat the 02 housing and turbine housing and exhaust manifold.

i just got my ported and jet hotted manifold ,turbo housing (not the 10.5hotside) and o2 housing from buschure,..
seems like good job,,,buti cant really tell since this is mah first time doing this,.,,,newbie....
i also ordered chrome manifold cover from buschure,,,it looks shiny,.,bling bling..
i m ready to install now! cant wait,,,i paid the whole thing for like $810
i hope it worths the money!

IF you end up doing you intake manny you should extrude hone it... and if you are down for it .. extrude the turbo .. cost bout 3-4 times as much as port .. but better air flow...
