I am in the early stages of installing a GT35R kit on my car and have no install instructions at all and have a few questions for those that might know.

1. Can I use the stock twin oil and water sources and returns for the new turbo? If so which return do I need to use and block the other off right?

2. I have a synapse wastegate and it has more vacuum lines then im use to seeing how do I hook these up? Ive read the instruction manual and it really doesnt make much sense to me.

3. I also have a synapse fuel pressure regulator and it has 2 vacuum nipples on it, where do I hook these up, im familiar with the single hose kind. Once again the manual wasent much help when it comes to rx7.

Thanks

1) yes, coolant are really easy. no block offs. Oil, block off the rear oil return. You will have a 2-3 inch pipe on the return line. if you remove that, the oil return flange on the block is the same as the flange on the turbo. Im currently sourcing parts from Aspec, they built my kit. but you can go to ATP and get 4AN feed line and 10AN return line The banjo bolt that feeds the oil is a 14mm 1.5 pitch thread bolt. its the same size on the end of the hard line feeding the turbos.

2) typically the side vacuum line is the line you run to the pressure side of the turbo; if you are just running of the wastegate spring. If its like a tial wg, the top line vents to atmosphere(i would recommend keeping it clean somehow) . if you have a boost controller, the top line is the one behind the solenoid.

3) I hooked my FRP as close to the block as possible on a nipple on the Lower intake mani. My sard only has one. Pics? if someone else doesnt contribute more relevant info.

 

Good info, I think you just about answered all my questions. Now i just need to figure out what im missing to hook them all up. Guess this is what happens when you buy a used kit.

 

lol thats why i gathered that information. :-) i didnt get oil lines with my kit. :-(

and the coolant lines were toasted.
