Evo 8 Turbo to 20G 10.5 Completed w/pictures!

I'm putting a 20G wheel and cover from turbolab on the stock evo 8 CHRA with a 10.5 hotside, this combination should make a turbo that flows more than an evo 9 turbo. Its only about a 170$ upgrade + 10.5 housing.

Update: 1/5/2015
Got the wheel and hotside on last night, went perfect. It seems the car picked up some niceable power, the spool sound is also completely different and way more aggressive.


Megan o2, 10.5 hotside, 20G

Found that the wastegate flapper designs are different on 9.8 vs 10.5 (9.8right,10.5left)

All done!

I've been wondering about doing this upgrade as well, also looking for some feedback before I pull the trigger on an FP red instead.

I ended up buying a Billet 7 Blade 20G and Compressor cover to fit it from Turbolab, they also sold me a 10.5 Hotside, Car should definitely pick up noticeable power.

Fp red is dbb and has a much bigger turbine wheen, with much better efficiency characteristics than an oem evo 9 turbine wheel. If you need an fp red performance turbo, you also need to upgrade the turbine wheel, otherwise there is not a comparison between the two.


As a side note, Kinugawa offers quality items and they are a good company to deal with in all aspects.

Did you do the install yet and are you doing the conversion on your own or having a shop do it? Thanks.

Can you post a link for the wheel and cover you bought from them? I'm still thinking about doing this as well. Thanks.

i did this on my 9 turbo.. I just broke 400 on pump gas. Looking to do some more internals to see if I can push it a bit further. Its nice little upgrade. You will notice it takes a little bit longer to spool but car pulls hard...
