New member, new 60 project

not sure how well this pic will turn out, but this is how they were run on that axt turbo 3b I had.

I kinda circled in red where they were attached, I don't know if this is how they're supposed to be, but it seemed to work.

it was a 1985 3b from a 60.

when you say "rigidly to the frame" with the exhaust, you mean with rubber exhaust hangers right? ( it'll rattle and clang without..)

The flange on the turbo becomes the stress point on the front part of the exhaust, the flex needs to be after the rigid mount. Its your project, just giving some input to think about. Looks good though.

I havent hooked up the water lines. I plan to but I need to figure out the best way. Where in the system would be the best place to hook in for cooling?

The AC wiring doesnt look very hard, but the turbo has been the #1 priority. I have an AC amplifier off an FJ62 which I heard will work on a 3b. I have heard a pulley off a toyota LE van will fit for an AC pulley; can anyone confirm this?

I think my wastegate is actuating at 4 psi (stock on the wrx is 7 psi, but I had to mount it differently which may have effected it). I turned up the fuel (feels like it accelerates about twice as fast as NA), but I still max out at 4psi at 1400 rpm and then it holds steady at 4. I am going to just wire shut the wastegate and see what it does.

As for the flex pipe, I think this mounting will be fine. Everything is solid. I will mount the exhaust rigidly to the frame right below the flex pipe. The BJ60 didnt have any kind of flexpipe and never had any problems.

Yes wire the WG shut and see what happens then tune backwards from there.
Exhausts are done all kinds of different ways, so long as its holds up and doesn't rattle all over... run it.
I plumbed water lines into rear heater circut for the return and for the supply I "T-eed" in before the heater core near/on the firewall. Works great. My turbo setup was one of those rare projects the worked great the first time and didn't require a million re-do's and endless trouble shooting. (other than tuning of course)

I have some pics but none seem to show the H2O line routing.

Today I disconnected and wired shut the wastegate. It was set at 4psi, and with it disconnected I saw 16 psi at about 900 F preturbo. I imagine I could make it hit 20 psi if I really gunned it. I am thinking I want to modify my wastegate or get another on there. Is there a general consensus on a safe maximum boost, or is EGT the concern more than maximum boost pressure?

 

[slowandsteady BJ]

Figure out what you want for max. boost and set the WG accordingly, then add or reduce fuel untill you get the EGT's to your Max level. The levels are debatable, all depends on what you feel is safe.

I feel 10-12 PSI will make for a safe happy little "B"
1200 deg. pre turbo is fairly agreed upon as EGT upper limit.

I run 12psi and with the intercooler I never see more then 1100 on the pyro no matter what. I could add more fuel safely but dont see the need. My big, tall, heavy truck can boogie up the Malahat at 90kph no worries and thats good enough for me.

Each to their own.

Good to see ya today at the MSM, truck is ubber nice almost rust free cept some surface...

Post up your mtn bike rack, I am interested what it looks like and the weight

After cutting all your pieces I think you could hank maybe 8 downhill bikes on that rack
