Hey man first let me say I love the look of this car!!! You've done a great job with it!
Now on to your tach problem. This is caused by leaking capacitors on the tach board inside the cluster. If you take it apart you will see corrosion on the soldered leads at the board. Just get new ones for the entire cluster. There is a thread somewhere that has the resistance values and you can get them all at radio shack. My car did the same exact thing!!! GL with it!!!!!

Thanks...I think the car looks pretty good considering her age.
In regards to the tach issue: that's awesome. I hope that's all it is! A simple fix.

You never posted up specs. Did you stay with the same turbo setup and fueling in this rebuild? I know the love hate relationship all to well, I'm glad you made it through to another rebuild. Ive always just looked at the fact of an Alltrac being the exact car I want. No other car will do.

I just realized you're right - I never did post the specs of the build. Life over the last three to four years has been a roller coaster ride for me, 90% of it bad, so the drive to keep up with the car and many other projects in my life sort of fell to the sidelines. I'm mostly done picking up the pieces, and as such my interests and hobbies are once again being met with genuine interest. I'll track down all the build info and put together a complete list of everything that's been done.

For a quick answer to your question, it's still using the same fueling(800cc injectors) and turbo(T3/T4 KO kit). I debated going the route of a stroker, but to me that is changing too much of the 3S-GTE. I sort of wanted to keep it "pure" if that makes sense. lol.

Totally makes sense. My last motor was a stroker with a 35R. It was fun but the issues and headaches of that build took a lot away from it. I went back to the basics with my current setup and couldn't be happier. I stayed away from changing what Toyota did with the 3S like you said.
Sorry to hear you were dealing with life's issues that pop up, I know that feeling all to well. It's a good thing you have that genuine interest in the car again, it can keep a man sane.

Your car must have been a beast with a stroker and that turbo! It's one thing that I wish my build had: a bit more guts down low. Such is the game when increasing peak power on a motor without increasing the displacement - up high and in the boost it's lots of fun, but street manners really start to suffer down low. Low RPM the motor is just not responsive with any degree of authority. Where I'm at now with the car I think it's a good balance of usable power and peak acceleration-madness. lol. Could go with a larger turbo one day, but at the expense of low rpm power/torque (regular street driven road manners) I don't think it's something I care for as I don't really track the car. It's just a fun road toy to enjoy the corners and the straights when there isn't anyone around.

I really can't wait til it's all done and I can just enjoy the car, take part in some car meets and cruises, and tackle the small maintenance issues that pop up along the way, and even smaller cosmetic things that I'd like to change.

In regards to the misbehaving tach - I pulled it apart and sure enough it was those two problem capacitors. I've ordered up two replacements, 10 microfarad, 25volt max, 105*C. Once they're here I'll do the swap with my fingers crossed!

Eventually I'd like to pull my rear diff, get the exterior housing blasted and coated as the thing looks like a sad rusted little bastard.

Quick update. Tach has been repaired and is working beautifully.

Thanks. Sadly a lot of the picture links went dead and I either removed them or haven't updated them yet. Life has been quite busy and it's hard to find the time to dedicate to the forums like I was able to back in the day. And the car is still performing strong and is reliable. Just put it away for the coming winter months, pulled the rear diff, and I'm doing a custom rear poly mount for it as well as replacing the passenger side axle shaft oil seal. It's already been blasted and ready for paint. I'm thinking just normal black, or blue, but can't decide and really I guess it doesn't matter as it's hidden under the car anyways. Regardless anything is better than rust. ;)

Re: My "Nothing Crazy" Project

It's been a while since I've had time to be active on this, and I've noticed pretty well all of my picture links are dead. About a year and a half ago I was enjoying the car, racing 1/4 mile and 1/2 mile tracks and really started to hate that my rev limiter was set to 7K by the tuner who did the car last build. I had a built motor and head(stock valves though, didn't want to go larger) and decided to push it to 8K rpm. Unfortunately the tuner I took it to ended up blowing the living shit out of my motor by doing a brand new tune. Pics below. Luckily for me I have some really great friends, a few of which own NXT LVL Motors in Calgary. They took on this project and saved me a ton of money and time. We addressed many shortcomings of the old build and this new one is going to be so much better for a street driven car. There is a bit of wiring and odds and ends left and it'll be waiting for a tune in the spring. Future plans are to make the car cosmetically amazing inside and out. Brace yourself for a huge picture dump below.

The carnage:
Image

Image

While on the dyno we noticed the car really seemed to struggle with breathing - getting rid of exhaust. You could even hear it...a very strange sound. After everything went kablooie and the car was getting torn apart I noticed my 3" Motoria twin tip exhaust was a sham! Indeed it was 3" piping, but the outlets on the muffler were something like 1.25" ID each. This is something that I never really paid attention to back in the day when I purchased this exhaust. It worked out that I was technically running an exhaust not much larger than 2" because of this restriction. Ordered up a new 3" inlet muffler with much larger 2.5" outlets.

Image

Image

Next I wanted to address the poor flow characteristics of the stock intake manifold that no doubt contributed to my engine's demise. I even recalled reading about this problem in the "power primer" but didn't pay enough attention to this part. So, I sourced some material and design specs from a great guy from Calgary who is on these forums, and who also helped me out massively with selling me parts for so incredibly cheap. Not only did I pick up the intake parts/design but a set of pistons and crank for a stroker build. Below are some pics of the intake fabrication and customization to get this to work on my engine bay.

Image

While the engine was apart it was decided I needed a new block, so one was sourced. Another 2nd gen 3S-GTE block. A great guy who has done millions of port/polish jobs was curious to see my head and was very impressed with the design. Way to go Yamaha. He said he would do a mild port/polish and ended up doing an amazing job and undercharged me horribly for his services. God bless his soul.

Image

With the intake and exhaust dealt with we also decided to go for a pricey turbo upgrade. I wasn't after crazy peak power and wanted something a lot better suited for street driving and the odd track day. This meant twin scroll. After looking at different turbos and whatnot it was decided to go with a Borg Warner EFR series 7163 twin scroll with integrated boost control solenoid, bypass valve, and internal waste gate. This of course meant making a custom tubular exhaust manifold to properly position the turbo so I could still use a 3" downpipe, retain the air conditioning, and still manage to clear the clutch slave. The flange I sourced online turned out to fit horribly. The ports lined up like ass, and the stud holes were so badly matched that the thing wouldn't fit. I had a second head at home and took some measurements and did up a cad drawing and had a stainless steel flange cut. This one fit so much better. A jig was made to position the turbo properly, and NXT LVL Motors went to work. If anyone is interested in this piece more can be made.

Image

With this done the downpipe needed to be made, and had to clear the AC compressor. Many pie cuts later the 3" stainless downpipe was done, and like the manifold and exhaust side of the turbo it got a full treatment of ceramic coating.

Here's a mashup of various pictures through the stages of the build.

Getting some paintless dent repair done on the passenger fender. Also notice the previous shop's intercooler mouting tab on the driver side broke so my intercooler is crooked. This bothered me so much. Is now fixed!

And of course some PROPAGANDA pictures :D and some other pics of the car.

Car is looking great! After tune what power did your car make? This is the turbo I was looking at getting for my sti and have been debating it for the alltrac.

Thanks. I don't have it tuned with this setup yet. My old setup was ~330whp at 17-18psi 94octane if I remember correctly. We are guessing anywhere between 350-400whp, to be conservative, on pump gas. I'm debating just tuning it on 91oct and running 94 for safety sake. I can't keep replacing motors, it's too much money. Haha. E85 isn't available at pumps here.

How much boost are you planning to run? I know 25 psi should get you 400ish whp. With full spool around 3800rpms. Should be a super fun car at that point.

For the pump gas tune it'll be around 18psi. I'll be getting it tuned on race gas as well, so I'll have to see what it likes on that fuel. I think with the increase in displacement and the much better turbo it should have a much more usable power curve for street driving. Once I get it on the dyno I'll post numbers for anyone who is interested in using a similar turbo.

Nice job!
I would have gone for the same turbo but it wasn't available yet when I bought my EFR7064 twin-scroll.
