finally ported my turbo

rushdylan · 12-13-2012, 05:43 PM

I've been port and polishing heads for motocross bikes for years, my wrx spun a rod bearing so everything is apart. I figured what better time than to port the stock turbo which I'll use for another 4 or so months till I pick up a 20G? after a lot of man hours, I have the exhaust housing 90% finished. the exhaust inlet is all finished but the exhaust port still has some work to be done. I couldn't finish it because I ran out of supplies so I'll need to buy more in the next few days to really make this thing pretty! also found a crack on the waste gate hole which will need some attention before this thing goes back into commission. the intake housing will definitely get some attention once I get more bits for the die grinder. hopefully i see at least a minimal amount of performance gain from this itty bitty thing. here's some pics!

Not bad looking. I wish i had pics of my old VF30 that was ported & polished from deadbolt many moons ago.

That looks awesome. I have seen dyno charts that show port and polished td04's adding ~15 HP.

that's great! I wish I had specs telling me how large to make the intake. I think since it's such a small turbo that the bigger the better. but we will see what I end up going with

nice. it looks good. i ported and polished my td04 also. i think i went larger on the turbine inlet though. i made mine 2" roughly and i didnt touch the outlet, i didnt see the outlet netting much results. also have my compressor side ported and polished. i noticed good results. but i also did an up pipe at the same time.

out of curiosity, what bits are you using to port and polish with?

I'm debatin if I will go larger on turbo inlet. maybe I will leave the outlet alone because it wouldn't make sense if the air came from the smaller intake housing into a big ass port. it would let it expand and basically lose pressure in turn. although it might not register on a gauge. I have this whole kit I bought from summit racing. it uses a little rod that goes into my 1/4" die grinder and the sanding tips thread onto the rod which tapers at the top. I polish first with a blue sponge type deal and finish with a softer red one. I've had the ports on my 250 looking exactly like a mirror and by that, I mean I could see my eye lashes in the reflection! carbon simply wipes right off of it

Does it perform any differently?

motor is still apart from the spun bearing. can't tell you yet! but I expect something like 400-600 rpm sooner spool at least
