Hey Guys

Ive been fabricating a custom built high performance turbo setup specifically for the EP3 chassis and its getting close to completion so i thought it should have its own thread.

I'm sure all of us familiar with k series turbo setups know how much a pain run of the mill side mounts can be. First off you have to relocate everything and its mother away from the mass of hot pipes now running right behind the valve cover. Then you have to deal with heat issues from the down pipe that's usually running right by the brake master not to mention having a dump tube snake around everything. And last but not least is problems with the actual turbo location. Some companies even decide to angle the turbo past the recommended 15 degrees maximum for the center section. This can lead to excessive smoking out of the down pipe and possibly even lead to premature bearing failure.

I designed this manifold with complete consideration of all these issues and problems. The first one was built off of a TSX with the help of LoCash, however sadly enough his manifold never reached a fully completed stage. Fast forward to now and after tweaking the manifold a bit more and playing with gate locations its almost ready to breathe some k20a3 fire. One issue withTSXs/ Ep3's and I'm assuming Rsx's is the room or lack thereof to even install such a large piece of metal from the bottom without unbolting a bunch of stuff and dropping the subframe. I had to get a bit creative....

The CTD K series T3 Top mount was born, dubbed affectionately "The Special K"



Here is a pic of turbo placement on a K24 in a TSX. 35R T3 open, 3" downpipe. This engine bay is quite a bit cleaner than mine so I'll put these pix up first, haha.





57 Trim, nice little 400 hp setup



Not yet ported 100%, flange also needs to be machined















Little more progress on intercooling this beast.

So I like options, that's why I will be designing this kit with both a Water to Air Intercooler and a normal Air to Air front mount. I ordered a nice little 500HP core from Bell Intercoolers and started brainstorming.



After discussing with our in house engineer about end tank design we decided to go a bit more in depth so he CAD modeled the core with tanks and did a complete CFD Analysis. This is the start of the design process to fabricate the best end tanks possible to utilize the core to its fullest potential.





I hope to have a downpipe tacked together tonight, clearance looks to be the same as a TSX chassis, full 3" with room to spare. I have kpro and a walbro ready to be installed.


Any comments or suggestions are much appreciated. Thanks for reading guys and this is my personal car so i plan on making the very best kit I can. This is also my first full K build so if you have any helpful tips please feel free to share.:up::up:
