modifying stock turbos
 

on my evo, i upgraded the exhaust side with a larger wheel and housing. it responded great and held boost longer with lower intake temps. not to mention i droped from an 11.97 with the bone stock turbo to a 11.77 and gained 5 mph with this simple upgrade. Ive been searching this board and havent seen anything remotely like this except for BNR stage 2 which i dont think they make anymore. and these were just rebuilds using larger wheels. Ive rebuilt my own turbos before in my audi s4, using k16 compressor wheels, and k04 turbine wheels in ported 0 clearanced stock housings. it was great and didnt even set me back a grand. I want to know if there are any wheels for turbos from other cars that are capable to use in the stock turbos? i have people that can port and clearance the housings to proper fitment if need be. has anyone reuilt their stock turbos using larger wheels? a link to these threads would be nice.... if they exhist.

The BNR Stage 3s are aftermarket CHRAs in modified stock housings. You can't upgrade the Hitachis as easily as you did with your BW-KKK/Mits turbos on your other cars.

Does clipped turbine blades give much on a modded FD??

No, and it increases lag.

yes, ive seen these. honestly, if im ganna fork up money that these would cost im going single. so why doesnt clipping these turbos give as much as other cars? i ported and clipped my 15g turbos on my stealth tt and notice a tad of lag, but much more up top. why wouldnt it help these turbos expell gasses better?? it should work just as well as other cars shouldnt it?

also, i thought the brn stage 3's were larger housings? iu saw a pic of them next to stockers and they looked much larger.

Port w/g?
