I am sorry, GC89, and everyone else kind enough to read my thread. I have been weighed down with a longer work schedule(I'm sometimes gone 10 days at a time), relationship(life) obligations,
and I will admit that buying the 89 turbo has taken away a lot of my time as well. Add to that, a lot of back and forth travel to NY for a family emergency for the past several months,
and I haven't had time OR money for my poor '88.
Having said that, I do promise to provide progress within this month.
Thanks for looking through it all. Unfortunately, I haven't been very active with the project lately.
When last I was working on the '88, It had developed a bad oil burning issue. I pulled the turbo(brand new PTE6266) and it had been pushing oil through the rear seal.
I really don't know why, as the drain is AN10, and very vertical, and I have a restrictor on the feed. I've replaced the seals in the turbo, put in a temporary see-through silicone
-10 feed(so I can see if it backs up), and reduced from a -4 feed line to a -3feed. We'll see if that corrects the issue.
Sadly, I've been putting time, energy and $resources$ into my '89 daily driver. But I've pretty much run out of things to do to it, so I'll be back on the '88.
All that's happened lately, is that I've decided to go with an ECU master DET3 piggyback, rather than the maft pro. They're quite similar, but I
did like the idea of launch control and a few other features that the DET3 offered. So that's sitting in a box, waiting to go in.
I also bought a stainless radiator 'cooling' plate, mainly for aesthetics. I hope I can offer updates in the near future, and
thanks guys, for taking the time to read my 'addiction journal'.
Well, I'm trying to wean myself off buying stuff for the 89 Supra(new oem shift knob, custom fit floor mats and sunshade this week).
Today, a package finally came in for the project car:
Yay! New fan blade for the '88. The car DID have a new fan, but the '89 stole it. So here's the new, NEW one, mounted on a new clutch.
And installed with a new shroud(the '89 stole that, too):
That's all I could do today. It started raining outside, and I have to get under the car to reconnect the exhaust.
That, and I had hernia surgery on Monday, and my belly started hurting, so I punched out.
No pics of it yet, but I have pulled the maft pro out, and begun wiring in the DET3.
I had purchased this piggyback used, so I was a little scared that it might be faulty.
I plugged the det3 into my laptop and gave it 12 volts, and thankfully, it seems to work.
Since it has an internal map sensor, I was able to blow into it, and see changes on the laptop readings.
On my next set of days off, I fully expect to have the car running on the DET. Then it's time to begin bodywork. Finally.
PS- I picked up a new targa tool bag from the dealer. The car never came with one, though it did have the tool. It was only 9 bucks. I found out that all the targa cosmetic caps(plugs) are discontinued, but I'm looking into the mk4 caps, because they look identical. I'll report back.
So, I'm slowly chipping away at the DET3 wiring.
The manual is a bit less than informative, but I'm slowly getting everything connected.
All that's left at this point, is wiring in launch control, map switching control, and running the reference line for the built in map sensor.
This last one required me to rearrange where the sources were for the BOV, and map reading, as I don't want them from the same source.
My Synapse valve uses the push-to-connect type fittings, so I pulled out the oem BPV hard pipe, and will be welding onto it a 1/8npt female fitting.
Then I can go push-to-connect from there, rather than at the back of the intake manifold.
Yup. I have measured the 'thickness' of both the NA and turbo fans. The na is a shallower blade, and does not extend as far forward into the radiator.
I had a turbo fan hit the shroud and break apart, due to the increased thickness of the Fluidyne radiator.
Got the fitting tig'd on today.
Well, that's not exactly true. The factory tube was too fragile, and the guy couldn't tig the fat fitting on without melting it.
So instead, he welded it onto a tube section with thicker walls. Then I chiseled off the bracket and mig'd it on at home. I was even able to
mig the bottom barb section on without burning through.
So, a small update,
I do have the car running now on the DET3, although there are still a few issues to correct;
My rpm reads 175 at 900rpm, telling me that my ignition configuration is incorrect.
And my GM iat is showing -40 degrees celcius. Otherwise, the only additional connections I need to make,
are the fuel map 1/2 switch, and the launch control. Then I'll button up the ecu and put the glove box back in.
Over the next couple weeks, I will be replacing all of the dead links that I can, and adding a few new pics.
Yesterday, I installed the copper crush gasket for the turbo's Vband clamp, and that solved the leak. So, I was finally able to
reinstall the compressor cover, turbo blanket and all of the intercooler and intake pipng. It's the first time that the motor has been completely
assembled in over a year and a half.
Today, I played around with the Det3 a bit more, and got the afr's balanced out in the lower half of the map. I actually took it out on the neighborhood streets for a short drive,
just to watch the afr log at higher manifold pressures, but my street is too small to actually let me get into boost in second gear(speedbumps). But it's running pretty well.
Once I make the last two wire connections on the Det3, I will begin Stage 4- body work. Time to remove all of the trim, moldings and weather stripping, in preparation for paint work.
true, I hadn't considered the posts about pics that are no longer there. I like having the first post as the complete build thread (like mine), but if you didn't start it that way it wouldn't make sense to change it to that setup
Man, It's easy to get delayed, distracted, demoralized, or just plain lazy, when it comes to a project.
I think my problem has always been, that I bite off more than I can chew, in terms of scope.
I have a hundred different ideas for a hundred different parts of the car, and when you get pulled equally in 12 different directions, you end up getting nowhere.
My '89 Supra has been a bit of a distraction; upgrading it, and making it nicer, has taken my time and focus away from my '88.
And since it is a car I can drive everday, it's been getting what little attention I can spare. I still have 3 or 4 small chores to finish with that car.
but in an effort to get back to this one, I decided to get a different set of wheels for it. The FR500's went on the '89 daily, and I wanted something a little
bit more 'boy racer' for this car. So I picked up a set of Varrstoen ES2's, and had them powder coated a custom color:
These are a square setup: 18x9.5, +30. The tires I chose are Federal 595 RS-R's, in 255/35/18.
Wheels should be nearly the last item one gets for a project, but I needed the visual stimulation, in order to continue the project.
This week, I hope to get good(warm) weather, so that I can finish the strip-down for paint. In the mean time, I'll continue to go back and replace the broken picture links.
Today, I just did a quick swap of the rear wheel studs, for slightly longer ones.
This was because I wanted to use a set of 10mm wheel spacers. the rears seemed to look slightly sunken in,
compared to how aggressive the fronts are, even though it's a square setup.
It's been awhile since I've worked on the car. About 4 months ago, I bought a set of leather seat covers, and it's been painfully slow progress on those. So far, I only have the rear lower cushion done, and half of the passenger seat. I just haven't been motivated to do it.
Add to that, a blown head gasket and complete motor swap/ upgrade, to my '89.
Buying a second supra was somewhat of a mistake. I mean, buying a Supra is never actually a mistake, but with respect to staying focused on my '88, it hasn't helped one bit. And on top of THAT, I just bought my first motorcycle, so that's been sucking up my time and effort as well.
I did, however, get started on one little task that I had been planning, and that's a hood vent. I had played with the idea of getting a carbon fiber hood, but I'm still not sure that it's what I want as far as look. So for now, I did a little cutting on my steel hood.
Anyone recognize the duct? It's from Toyota, afterall.
Sorry for no progress, but I am making headway with the upholstery replacement,
Back seats are done, and just about finished with the front passenger seat. It's a lot more time consuming than I expected.
I ran out of hog rings, and I just got some more in the mail, so hopefully, I'll make good headway today.
