Amazing project. This DIY effort is comparable to the best that have been demonstrated on this forum. Thanks for sharing. Only thing of value I think I may add is to realy consider ditching the dual Walbro fuel pump setup which is potentially unreliable and risky, and instead reconsider a...

+2 for Innovative. Grassroots Motorsports Mag. performed a technical study and write up about all the relatively affordable aftermarket W/B's and determined that the Innovative was top notch in both price / value and performance. They also reported that the Zietronics was the most cost...

Both are M12X1.25. For improved oiling and cooling recommend ditching the OEM cooling & bleeding off concept. Instead, go with a remote filter / cooler and oil thermostat setup.

Please take you car to a dyno to get it tuned properly so that you can learn how it's performing, and what you're limitations are with current fuel / turbo setup. Otherwise.....

Don't get too upset. -- Several automotive insurance companies in the USA still list the MkIV's as Celica Supras also.

Excellent job and performance results Brent. There is much more left in that turbo, so enjoy it and tune properly / carefully to yield all the fun and enjoyment. GREAT JOB..

^^^ Yea, like how to order? Sorry if I missed that ...

My comment / suggestion was solely based on your mod' list; 1000cc inj + Emanage. You must realize that 1000cc inj is 250% larger than the originals, so your tuning maps will be so incomprehensibly skewed you'll be lucky to get it to start and idle properly. Idling and drivability will be...

Hmmm, Sratch Emanage piggyback and substitute some type of standalone EMS. Turbo will be a bit laggy, but eh, one must make compromises with a turbo capable of 750+whp.

Sounds like a dip in performance during the transition to higher boost levels. Could be plugs, fueling, wiring, your EMS, or your present MAP program. Post up the dyno curve. In regards to your question, no, this is not compressor surge on decel.

The risk of buying a cylinder head from ebay is that you are quite not certain on overall quality and useability of it. Without visually inspection, you can't really tell what you are getting, and that becomes a huge risk / gamble. Benefit of the local machinist is that you can develop a...

It'll also be a great idea to install zerk greasable fittings before you go any further ;)

Yellow will be one of the color choices?

That size would be ideal for normal street use, but if you intend on doing any type of road course racing, then minimum 16 row is recommended.

The circuitry in the "TFB" is designed to sense a certain inpedance for the primary rear brake light lens and the secondary (3rd brake) light lens. N/A's are probably all the same (I didn't check the online EPC), however, all others are different depending on the rear spoiler that's been used...

Yea, I would agree. Need additional information, such as material, and description of how the loading / constraint were applied. Additonal question. Can Ansys run a design case by continous repeating a particular user input, such as load, and with successful iteration until a user defined...

Technically, JDM SC300's (or Soarers in that part of the world) all had 1JZ's in them ;). So, since seller is obviously oblivious, then I'll stay away.

^^^^ Hmmm, the "archaic" 7M's ECU does that too, ;) , along with just about any other EFI automobile with knock sensor feedback. Basis of all EFI with O2 sensor and knock sensor feedback is to continuously update the base maps based on the sensor feedback and engine's operation and condition...

Anyone will say anything to make a sale. The adapter needs to angle upward for the turbo's compressor housing to clear the shock tower, else it will hit. Only a small (puny) size comp' housing will fit with that straight adapter

Ha, not unusual for Supe's and other IRS and manual tranny cars. It used to be a joke and laughing matter at the drag strip few yr's ago; "Show me a 800hp Supra, and I'll show you a 13sec car". :)
