Cas' 800+ or Bust Build

Thats what I used to mount my Walbro to the stock tophat:



-6AN 90* Bulkhead fitting Male to Male
-6AN Straight Adapter Female to Female
-6AN Radium Walbro Outlet

Still yet to install and test but hopefully shiuld work fine with the stock feedline for the return

The brake fluid reservoir does also feed the clutch master and slave cylinder. However, even if your clutch fluid all leaks out on the ground there is a step in the reservoir so that the brake fluid will not also fully drain to the point where you get air in the brakes. When I had my engine out I let the clutch line leak fully out but brakes stayed just fine and I did not have to bleed them.

 

Sorry I just now saw this reply, I don't remember getting an email for the reply. That setup looks solid! I don't have any doubts that it wouldn't work.

Anyways I know why I'm popping lines off. In changing baskets and everything I didn't put the OEM FPR back in so basically nothing controlling the fuel pressure. I have a plan to just run an aftermarket regulator pre-HPFP and that should solve it. Pretty dumb mistake, not sure what I was thinking when I was going through everything.

On the clutch issues, I bought a power bleeder so I can bleed the system myself just haven't gotten around to it yet. I ordered a new TOB today because I'm leaning towards that being the under lying issue, it was only 40 bucks and good to have on hand even if I don't need it.

 

For 450 pump mod I make sure they are running an external FPR. The way i run and the way j recommend is splitting the feed to the HPFP and PI this will use the FPR on the PI for the LP system.

 

Yeah that's exactly what I'm going to do now. Just figuring out what PTFE line I can still use since I ran everything and extra fittings I need. Should be ordering everything in the next day or two. No real rush since it's cold here now. It would be nice to go WOT again with out worrying haha

 

Is it too late to say Happy New Year since I haven't posted since last year? lolz

Car is doing okay, I fixed my fuel issues with a corrugated hose from Radium. I also bought the hard lines like @TRBLSM posted above, they will work just haven't gotten around to changing it because you know still having issues in other areas. My clutch is pretty much dead. I guess the TOB or something is f'd up so now that I can go WOT without worrying about fuel issues my clutch slips anything over 5 PSI. I'm pretty sure I had a TOB issue that would cause it to not engage all the way and must have pre-maturely worn the clutch. I emailed OS Giken and it's 150 bucks to send off my twin disk for them to inspect to see if anything is wrong with it since Oddball couldn't get it to work originally. My OSG clutch has been sitting in my garage collecting dust so I figured I'd try and use it this time around. I'm going to do that when i get my bonus in a couple of weeks. My driver's side outer axle boot is torn again so I need to order a new one of those and do that while I'm replacing the clutch. Not really sure what happened to it since I replaced all the other boots and they are fine. Anyways that's it for now, I really wish I could be posting that I finished my PI system but with all this shit happening I don't feel like messing with it. I just want to enjoy the car.

 

Glad to hear you're pushing through I really want to see it make some jam. My clutch has been holding fine so far I hope I'm not going to have similar issues as my engagement is clear at the top too.

 

Figured I'd make an update, it's been awhile. I'm a dad now, my daughter will be 7 months old tomorrow! So that's partly why I haven't posted anything or worked on my car. Also laziness. I'll try and make the update short. Car still has issues to work out but I'm driving it. Long story short I installed the OS Giken twin disk again and it didn't work again so I just ordered a new ACT 6 puck. While my car was down I made all my fuel lines to a have a full return fuel system. If I get some time I'll post some pictures later on. I have two Aeromotive 325LPH pumps in the tank, a -8 AN line coming from the tank out to a Y adapter, one side going to the HPFP and one side going to the supply side of the PI rail. Post rail I have a FPR going back to the original supply line which now the return line. It's pretty simple but cutting all those AN lines was a PITA and time consuming. I had a couple leaks when I first started it up, one was just loose a little from moving around during the transmission install. The other was by the fuel tank and was barely seeping out from the fitting. The fitting had a burr on the threads so I ordered a new fitting and haven't seen any issues with that.

I haven't had any issues with the fuel pumps in tank disconnecting like they were before so that's good. No more getting stranded from a fuel pump issue, fingers crossed.

The latest issue I'm dealing with is the dip stick tube is popping out barely going into boost so I'm just getting too much crankcase pressure. I just ordered this:

Also thinking about adding a spring to the dip stick so it doesn't pop out. Something like this:

I have two sealed catch cans on the car now and I have one vented Damond catch can sitting in a box in my garage. I'm thinking of swapping one of the sealed ones for the vented can. I hope adding the valve cover breather and the vented can would fix that issue.

For the other issues:
1. Exhaust leak somewhere. I think it's where the downpipe meets the mid pipe but I haven't actually looked yet. Not a big deal just smells when I drive the car
2. I'm throwing a code P0717 Fuel System Lean (Bank 1), I'm assuming it's related to a vacuum leak somewhere. I can go into boost just fine and nothing is lean. Haven't really done any troubleshooting besides making sure everything is tight as far as couplers and any vacuum lines. I've taken the car apart several times and it comes back every time.
3. LTFT is off and shoots to the max +20 or whatever the number is, I'm assuming it's related to the code.
4. O2 sensor is on it's way out again, also probably related to the above issue with running rich or lean at idle. I have another one ready to install.
5. Get AC recharged
6. Not really an issue I just need to take the speed 6 slave cylinder off and install the modified supra slave so just adding it to the list.

 

Do the supra slave sooner than later , don't want to over extend the pressure plate. Have you done a boost leak test and check your pressure relief valve?

 

I have been babying the clutch so far until I can get that installed. I've only driven it a handful of times. I did do a boost leak test but my tester started leaking at 10 psi so I need to make a new one or repair the one I made. I have not checked the pressure relief valve but I think it's okay. I can do that test when I get home to see if it builds pressure after the car is shut off.

 

You need to make sure the car is all the way warmed up for that test.

 

I should have been more clear, I was going to run the test after driving home from work so it'll be warm
