so i am upgrading my turbo and i need to know where/what size flanges i need to use to adapt hoses to my block where the old water and oil feed/return lines go. i'm sure atp turbo has them but i don't know what will fit.

 

i have a couple of them i would be willing to get rid of...

 

Here is what I did for the oil feed supply on the engine side. I bought this:

and I had to use a die to change the pitch from 1.25 to 1.50 . You may be able to find a fitting that is already 1.50 . On the turbo side for the feed line, you can try something like this http://www.atpturbo.com/Merchant2/me...egory_Code=TBN
but you may need a restrictor. Then you can buy a pre-assembled 4AN oil feed line or make your own. You will also likely need two 90 degree 4AN fittings, one on each end, depending on the setup.

For the oil return line you will want a 10AN fitting like this http://www.atpturbo.com/Merchant2/me...egory_Code=TBN
for the oil return on the bottom of the turbo and a replacement flange for the block (remove that short little straight piece that connects to the stock turbo's oil return line, and connect the new return line directly to the front cover). I'm not sure which flange you need that actually goes to the front cover. Also, the oil return line is an enormous bitch, or at least it was for me. You have to make one that is almost perfect. SS line isn't that flexible so if you don't have it just the right length it will kink and not thread on to the fittings. Do not use anything but SS line for the turn! I do not trust it with the heat of a rotary engine. I can't tell you exactly which fittings you will need for the hose itself because it depends on how the turbo is clocked, but I can tell you that you will probably spend a lot of time on that return line. Remember that if you are not careful, oil will back up and cause problems. I made my own line by trial and error, cutting about a centimeter or two at a time off SS hose (and then installing the fitting to mock it up, then removing the fitting) until it was short enough for the fittings to thread on but not long enough to droop and cause oil to back up.

I can't help you with the coolant lines, my turbo is only oil cooled so I blocked off the coolant feed with a split air blockoff plate and the coolant return with a big vacuum cap and a hose clamp.

EDIT: Other option is to check this website http://www.2751engineering.com/2751parts.html . I've never used the kit though, but I am happy with the blockoff plates they sell.
