The next step was to address a few quality issues. Brand new fog lights were purchased form Toyota to replace stone-chipped original units. Xenon-white bulbs replaced ordinary lightbulbs. Targa roof also received new treatment. New rubber seals were installed all the way around. Door seals were also replaced with brand new units. Same happened to the trunk seal. All new, nice and soft rubber. Next the old carpet went out, replaced with Black, molded 20oz cutpile factory-quality piece, with rubber soundproofing backing applied. Both, the cabin and trunk area sections were replaced. Brand new, factory Toyota leather shifter knob was also purchased and installed, matched with the black leather shifter boot covering a short shifter. It is a factory original unit modified the way that retains the original rubber bushings, helping with precise and quick shifts while retaining most of the original vibration-free feel. Center console armrest was also covered with new black leather.

One of the next mods was an addition of AutoMeter gauges. First a double gauge pillar pod from Lo-Tek replaced the factory a-pillar trim. Then a pair of 2-1/16″ (52mm) gauges was installed: a boost gauge and a coolant temperature gauge, both with dashboard cluster matching green backlight. It seemed like a great addition, however, because the needles were not illuminated, night time readouts were less than perfect.

To improve intake air delivery a K&N Cold Air FIPK kit was added. Installation was very easy, a drop-in application, although clearing the Greddy BOV was somewhat challenging. A polished stainless steel shield next to the intake was also added to reduce warm air intake coming through the radiator. Toyota factory Air Flow Meter (AFM) was polished to improve the appearance.

Only a couple of years ago this car was still a fairly stock version of the Toyota Supra Turbo. 130,000 km original mileage. No winters. Factory original Ruby Black paint, grey leather interior, stock internals in the 7MGTE motor. A few BPU mods were implemented to improve performance. They included: Suspension Techniques anti-sway bars, custom modified polished 3000 pipe with removed bottleneck, large intake pipe with Greddy type S blow-off valve, Fluidyne radiator, Greddy Turbo Timer, and TRD Style 320mm diameter steering wheel among others. Also present were front Greddy replica and rear Cusco tower braces to aid in torsional rigidity. The Supra was on the right track towards a few more upgrades…It shortly received reverse facing hood air scoop aiding in evacuating hot air from the engine bay, polished aluminum upper radiator pipe, TRD oil filler cap to dress up the engine bay as well as aluminum race-style pedals.

CT26 (stock):
Compressor Inducer: 1.75″
Compressor Exducer: 2.559″
Turbine Minor: 1.97″
Turbine Major: 2.36″

Good for approx ~31lb/min (about 450cfm) of airflow, around 13.5psi. I would not exceed 13.5psi, though you will hear of people pushing 20psi. If you want the turbo to last, do not exceed 13.5psi.

CT26 Upgraded:
The CT26 upgrade is great for those on a budget, or if you want a super-fast spool. The upgrade consists of sending your stock turbo off to a turbocharger shop, and having them bore out the compressor inlet to fit a larger compressor wheel into the CT26. Generally, T04e wheels are used, though I have heard of T04b wheels being used. Bang for the buck, it is hard to beat the upgraded CT26.

The downside to that great spool, is you still have the restrictive exhaust.

Upgrade levels one may choose from:
50 trim - Considered the most reliable upgrade.
Compressor Inducer: 2.12″
Compressor Exducer: 3.00″
The T04e 50 trim wheel is rated @ 44lbs/min @ 2.0PR, and 65% efficiency at that point.

57 trim - The most popular upgrade, while still being very reliable.
Compressor Inducer: 2.23″
Compressor Exducer: 2.95″
The T04e 57 trim wheel is rated @ ~40lbs/min @ 2.0PR, and 60% efficiency at that point. Raymond Khublal in Orlando, FL has laid down 422.1 rwhp/460.2 rwtq as shown on 7Mpower.com with this turbo.

60 trim - Not to be confused with the 60-1 upgrade, this is a less reliable variation of the 57 trim. More power is to be expected from the 60trim vs the 57trim.
Compressor Inducer: 2.29″
Compressor Exducer: 2.95″
The T04e 60 trim wheel is rated @ ~46/min @ 2.0PR, and 65% efficiency at that point.

60-1 (T04b) The 60-1 is a T04b wheel, and the biggest seen on a CT26. The least reliable upgrade, but has made the most known power.
Compressor Inducer: 2.324″
Compressor Exducer: 2.95″
The T04b 60-1 wheel is rated @ 56lbs/min @ 2.0PR, and 65% efficiency at that point.

These wheels are rated at a specific flow WITHIN their own respective compressor covers. The CT26 cover is small, so you will not get the 56lbs/min you want with the 60-1. This also holds true with the T04e 50 trim - it seems the best on paper, but we have yet to see one crack 350hp.
