luke, it looks like you might have the tensioner pulley set up wrong? Unless the pulley you got is a ribed one.

nope I think you're right, good eye. This is what happens when I start assembling without referencing my photos. Thanks dude



I got mine from gpopshop.com. You have to call them to order the ct20b kit



I used one of those 3M sanding sponges, the 320 grit iirc, and a can of CRC alternator/starter cleaner. I made sure to keep any sanding dust from building up by using my compressor often. I took it to get tested at advance after and it passed with flying colors

Hello 6gc,

I have a massive update for you. I've rebuilt my turbo, and I'm slowly making my way through extending the wire harness. One of the most tedious things I've ever done, and I've done my fair share of tedious stuff during this rebuild


A while back I ordered a late model 5s engine harness from ebay to serve as a donor for my extension. I figured that since the 5s and 3s are so similar, then most of the wiring should match up color-wise. What you see in this photo is the leftover carnage from unlooming that donor harness.


Here is a shot of the exposed wires waiting to be sorted and cut. I made sure to measure my st205 firewall and figure out the approximate extension length before I scrapped it. I would only need about 36 inches of additional wiring to make the 3s harness plug and play with a lhd frame, but I decided to play it safe and go with 42 inches.


Next I exposed a section of my 3s harness near the firewall boot so I could start sorting and making a log of the wires that would be supplied by my donor.


This is the result of the sorting. I was missing about 20 color combinations so the next day I tore into some leftover chassis harnesses from the clip and salvaged about 8 more. So that leaves me with 12 color combos un accounted for. It's no big deal though, I will just use wires that look similar and properly label them.


Here is a picture of the log that has been helping me keep track of the wiring. Its super easy to get confused so something like this is a must in my opinion.


This picture shows my workbench all setup for the extension. On the right are the soldering supplies I've been buying lately, including some quality 3m electrical tape. Those of you that have used a lot of electrical tape before know that the cheap stuff either melts together or gets really brittle. I want to avoid that with this harness.


I'm just starting the extension in this picture, but just those few wires took about 25 min. Each extension involves a cleaning of the donor wire so it's not sticky, cutting to 42", stripping all ends of insulation, careful soldering, continuity checks, and heat shrinking. Absolutely mind-numbing work. I'm also making sure to stagger groups of spliced wires to avoid a bulge in the final product. It's been mostly smooth sailing except for some unexpected coaxial, and shielded wires that the donor harness could not supply. I'm gonna have to get creative to extend those. Hopefully my soldering skills are up to the task


In other news I got my turbo parts back! That's just amazing turn around time, especially considering hurricane Issac was blasting Florida while this was there. I love how they cleaned up the ceramic impeller, way better than my measly attempts. Guys, I was the guinea pig and I can say without a doubt that theboostlab.com is the place to go with.


The intake side is looking pretty good too. One thing I couldn't figure out is where they removed the material to do the balancing. Maybe all it needed was to be clocked slightly to make up for the chips. Either way I cant wait to hear this guy spin up!


With the parts in hand I sat down and assembled the turbo with the new internals. Assembly is super easy as long as you take pictures of everything ahead of time. I'm surprised people don't rebuild their turbos more often. However doing this only reinforced my pure hatred for c-clips.


Nothing like a freshly rebuilt turbo


I wasn't about to sit around with a freshly rebuilt turbo on my table so I went into the garage and started assembling.


For a stock turbo the ct20b really is big. I have to hand it to toyota, they went nuts with the 3s turbo. Twin entry, ceramic exhaust impeller, water cooled... They just crammed in all the bells and whistles possible back then.


It feels real good to finally have the engine finished. I'm literally just waiting on a bracket and two gaskets at this point. Everything else has been done. Unfortunately now is the point where the real second guessing starts. There are thousands of places where I could have made a mistake on this engine. I hope none of them are going to be show stoppers


Another view of the assembled turbo. I'm thinking of just leaving the factory heat shield off for now. I like the way all of this looks, and I don't want to hide it.


Also got my prosport gauges in the mail. Boost, AFR, and oil pressure. I cant wait to have them bounce around while driving at night. Btw, I was really surprised at the quality of the supporting hardware for these. I don't know how anyone could want more.


Finally, I got a wild hair the other day ordered a QTP exhaust cutout. Making a custom exhaust is gonna be a pita for a while so this thing is gonna let me uncork the motor when the occasion arises

I plan to take advantage of the long weekend and finish my harness. The final parts should arrive by tuesday at the latest so... the swap is upon me.

I expect a startup vid within the next 7 days!

dont tempt me lol. I'm getting so close that it's all I can do to keep myself from halfassing stuff just to get it done

thats a stupid clean engine. I like it

shooting for this upcoming weekend!



Thanks man, hope to see your beams again next summer.


So this sucked. I never want to solder another connection again, but the harness should be very reliable (I hope). I guess time will tell

it has held well for me...

Good job.

your gonna have to cruise down to our neck of the woods!

what he said ^....holy mackerel!

If you want help Luke, let me know. I always travel with all tools necessary to assemble/disassemble celicas.

Sounds like a plan. Let me get this thing running properly first... and let me buy my Quaife







You will be the first to know when things start going horribly wrong.

lol we're engineers.... Firefighting is our job.

Truer words have not been said.



Engine threw a rod on startup . Vid later

swift
I will have a double long island iced tea because of this sad news!! I am sooo looking forward to seeing it at the spring meet!!
Best of luck!!

what!?! but everything looked so perfect..

sorry to hear about that.

Noooooo! That sucks terribly!!

What the...... Did it put a hole in the block? At least you know how to disassemble and reassemble everything now.

Video of the failure:
