lookforjoe Posted April 27, 2011 Author Report Share Posted April 27, 2011 Do the later heads have the same t-stat housing as the older? Or are the t-stats interchangeable? Reason I ask, where'd you get an 82C t-stat?? That would make me very happy I have a 92C, and by the time I finish third gear the coolant temps are at 98 sometimes if it's very hot out. That is not so good considering many of the failures on these engines point back towards cooling inefficiency at the tops of the cylinders. I used the early t/stat housing, modified to include the head vent The t/stat was purchased from the local autoparts store, I just asked for 82ºC - it came in a Stant package. I can get the part number for you when I get home. Hussein I don't think those bigger breather boxes fit under 93-98 manifolds. Oh Fuck I'll find out this afternoon. I'm using the ME7 NA intake. Won't be an issue when I get my custom manifold built, but if it doesn't clear (looks like the cam vent neck would be the issue), I'll have to switch back for now. EDIT: Just looked up the breather, and the NA version is completely different in shape... Quote Link to comment Share on other sites More sharing options...
sconeman Posted April 27, 2011 Report Share Posted April 27, 2011 yeah sorry, I saw that Jake had to change his out. good progress though otherwise! Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted April 28, 2011 Author Report Share Posted April 28, 2011 My solution to the breather box issue - the cam vent hits the bottom of the intake, so I chopped that down & added a new port just a little back. I have a used one that I cut in half, so I knew where it was safe to drill without interfering with the vent baffling used (new style) one cut All clear now, manifold fits over , no problem All back together & running Fuel & FPR vacuum hard lines are run under the upper timing cover, I notched it in two places to clear the lines. Just drove it gently around, so I don't yet know how it will perform. Vacuum is good at idle, back to 18inHg Quote Link to comment Share on other sites More sharing options...

Trent Yeah - I'm a public school teacher - I start @ 7am & finish @ 2:30. Been doing it long enough that I don't have to take much work home with me anymore. That gives me most afternoons to procrastinate on my master's thesis work, and work on the Volvo & the Fiat :lol: Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted April 28, 2011 Author Report Share Posted April 28, 2011 Part throttle log W/boost control turned off (15psi WGA) perhaps too lean in the second session - 4th gear, around 3/4 throttle Quote Link to comment Share on other sites More sharing options...

heat391 Posted April 29, 2011 Report Share Posted April 29, 2011 Difference between early & late breather box - outlet is in the same spot, cam vent is moved outward & cam vent hose is revised to accommodate the change Added my drain back port & installed Umm..... I know I'm new an all, ....and I don't want to second guess a much more experienced person, but after reading a bunch of threads and such, I thought the hose to the cam cover went on the passenger side/top port closer to the block, and the intake hose goes on the port that's more towards the driver's side/farther away from the block......

That's OK, your assumption is true of the old style box. The new box, they kept the same location for the box vent (because to change that would require reworking the entire composite vent/heater arrangement), and simply changed the cam vent hose to allow for the change in position.

lookforjoe Posted April 29, 2011 Author Report Share Posted April 29, 2011 Got on it a littler harder yesterday afternoon, now that I'm not afraid the valves are going to smack the pistons Timing @ AFR's look pretty good, so I'm going to start raising the boost (running 15psi in these, logger underreports by approx 1.5psi) I like the visuals, so: I fattened up the midrange/part throttle load areas by 30% to adjust for the improved breathing What's really nice is that the engine is far more tractable in the under 3K range now, I no longer have to downshift in normal driving when I need to get on it just a little - for example, I can be in 5th @ 2.4k rpm, and still have it pull without bogging. Throttle tip in, which had suffered since going to the 3" MAF housing, is much better now - not back to stock feel, but much closer. Quote Link to comment Share on other sites More sharing options...
550 Posted April 29, 2011 Report Share Posted April 29, 2011 Since swapping in my RN engine I had to bump up to larger injectors. And modify the map up top a bit as it was starting to try and lean out on me. I'm having some lean tip-in issues as well that I haven't tracked down just yet. Glas to see you got it running!

lookforjoe Posted April 30, 2011 Author Report Share Posted April 30, 2011 TT COP package arrived today!!!! Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 3, 2011 Author Report Share Posted May 3, 2011 Worked on revising the COP wiring & boxes to suit the way I want it installed - everything in the ECU box for optimum waterproof/weather protection. Moved the power supply to a Volvo 700 cruise control module housing - now it will fit next to the TT ECU Made the COP harness one piece from power supply to coil packs, lengthened the power supply cabling, shortened the ballast - power supply cable. Flashed the TT COP ECU with my tune & ran it to confirm basic functionality still using distributor. Had to make a shoulder to allow the COP connector to clear the ECU cover - the connector is too tall Should now be able to get all the wiring in the car during the week.

Any issues with what you did yet? I will probably have to do the same thing or switch to the old set up. How much play is there to drill with the baffling and such? Can you take a pic of the one you seperated? Quote Link to comment Share on other sites More sharing options...
