Turbine Housing Swap
 

Hi guys I'm from Sydney Australia and I'm new to this website. I'm going to get a Evo 7 in near future (probably in 5 weeks) and I'm planning to change the whole exhaust system, air filter and also lower intercooler pipe kit as my first mod from an evo specialist workshop. they also suggested me swapping turbine housing as the 7 and 8 Jap spec has the 9.8 turbine housing as oppose to 10.5 on the evo 9. They have a product GTPumps 10.8 turbine housing. They said it would definetly improve top end power.
1. Is there any how tos on this website on swaping turbine housing?
2. Is there anything I should watch out for when performing this?
They offered to do it but labour is expensive and I like installing things myself, I take more pride in the car knowing everything is done by myself. Any help would be great guys!!

bump. i need a link as well. doing a turbine swap asap

Very easy to do. If the turbo is off
1. disconnect the wastegate actuator
2. Take the band clamp off" 10mm"
3. Here you need to be careful take a rubber hammer and tap arount to losen the turbine houseing and I used a flat tip screwdriver to pry it free as 50k+ miles its a pita and then be careful separating it not to damage the turbine blades took me maybe 20 minutes to get off and 3 to put back together. When reinstalling be careful of the blades as well. There is a pin/round guide on the turbo that aligns back to a hole in the turbo houseing/hotside. Then tap with a rubber hammer to set it and put the band clamp on and then reinstall the wastegate.

This should help you guys! G/l

thanks!

Thanks for the quick info Beissen! Will definitely keep in mind on the how to install :D

Thanks for the info i have been needing to do that myself

Very simple, if you can take the turbo off you will figure it out. :D

I can't find the page right now, but I was reading and there was a company or person who did this swap and had dyno graphs to show the differences. He made it seem like it wasn't that big of an increase. Any thoughts??
