It's not a Celi, but i thought it might be of interest to some of you folks because we share the same engine
Here is a pic of the almost finished build:



I don't know if I'm welcome here without a Celi, so if you guys wanna see more just let me know, I have tons of pictures including some log files from my road-tune for the tech-gurus of you

Car is still going strong
But I had to replace the engine because the pistons or rather the piston rings I bought new of ebay somehow destroyed the whole engine
Just 100 km after I dropped them in, it began to make ticking noises. I was still in the running-in stage, so I didn't even stress it. I checked the oil and there was a lot of metal abrasion in it. So I took the whole engine apart again: Everything was f**king wasted, the camshafts where already scored on the bearings as well as the cylinders. Hell even the damn CT26 Turbo had scored bearings and shaft









I checked everything for a fault done by me during the build-up, but I could not find a single mistake, so it had to be the freaking piston/ring kit that was BS. I definitely never buy such a cheap set again.
Anyway, I bought a used 3S-GE gen3 in good condition and thought I could at least upgrade from gen2 to gen3 through this. But I had to realize that the 3S-GTE gen2 manifold does not fit the 3S-GE gen3 head like it does with the 3S-GE gen2... damnit. So I bought another 3S-GE gen2 head and put this one on top of the 3S-GE gen3 block, where I put used OEM Toyota 3S-GTE pistons in with a compression ratio of 8.8:1. It fits with only small modifications. Now the oil filter is in a better location and I don't need the relocation kit anymore. The gen3 block does also have better options for the turbo oil return, with that I could build a much more sophisticated and OEM looking return. I also bought a CT26 from a MK3 supra and rebuilt it. The supra CT26 has a larger compressor than the ones the standard 3S-GTE came with. The twin scroll CT26 turbine housing fits the supra CHRA, so no problems with that.













I put in 460cc injectors from a RX-7 and a flywheel and pressure plate of a Celica GT4 combined with a hybrid clutch disc from ACT because the S54 gearbox has a shaft with 20 splines unlike the 3G-GTE's with 21 splines.







I powder coated the intercooler pipes



The engine mounts had seen better days, so new ones came in.







To be safe, a walbro fuel pump replaced the over 20 year old pump







After that, the car already run very nice, but I could not raise the boost over 1 bar. I thought that it must be the exhaust system that generates a big back pressure, because it was never intended to support this amount of power.
I baked together a nice dual muffler system.









The result is a happy turbo which a lot of breathing capability
Now it runs with 1.2 bar of boost... and it is fast
