brake and ecu question
i have a 93.5 supra N/A and i know the tt brakes are far superior to mine. mostly because the computer for them is much more advanced. if i got the tt brake computer could i just replace it with the one that is in my car.
also i am doing a tt swap. hints thats why i want to upgrade the brakes. i want to know what ecu i would need to get if i wanted to us the 2jzgte emgine with the r154 tranny. are all of the manual ecu (like the one that comes with the manual 6 speed tt supras) the same? would it just be better to by the complete set up instead of buying everything separate? there is a shop not to far from me that said they can get me a gte motor with the r154 set up for 3200. what would you suggest. any help is appriciated. thxs |

 Getting your calipers and master cylinder upgraded are the first steps, to me. Your next step would be to install the actuator - which is a control valve which allows the ecu to control the amount of braking force applied to each wheel, independently. The mkiv abs ecu can't do its job unless it has this actuator. You'll need to run several new brake (fluid) lines to make this work. After that you can worry about the ecu and sensors you'd need (including the lateral acceleration sensor)... Here's more on the braking system. I promise you it's worth the time to read the pages you find at these links: http://www.mkiv.com/specifications/ncf/ncf93/ncf163.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf164.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf165.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf166.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf167.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf168.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf169.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf171.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf172.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf173.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf174.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf175.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf176.jpg http://www.mkiv.com/specifications/ncf/ncf93/ncf177.jpg Sorry I have to say this: The simple way to fix this all is to get rid of your n/a and save up for an Mkiv TT. If you want to end up with a full Mkiv TT, that's the cheapest and easiest plan...really!

okay i finally have enought money to start working on my supra. my ultimate goals are to do a 2jzgte with an r154 tranny. unfortunally i still am just shy of having enought money for complete swap altogether ie motor, tranny, wiring harness, ecu all together. i know those set ups are pulled out of the jdm toyota aristo an you have to do some modifications to the wiring harness to make it work in a usdm supra.
i do however have enough money right now to buy a 2jzgte with w58 tranny. this set up would include everything i need to get my car on the road. i know the r154 is much stronger than the w58 so my question is if i bought this w58 set up could i use the same ecu and wiring harness and just swap the trannys when i can get the r154. im just growing extremely impatient and what to get started right away. so i was going to buy the one with the w58. drive it till the tranny blows and the simply but the r145 and replace it can this be done??? |

- A manual tranny's connection to the ecu is pretty simple. I believe there's not much more than a couple of speed sensors. Contrast this with an auto where the computer actually has to shift the tranny. - The R154 is an MKIII tranny. Maybe if you posted in the MKIII section...something like "can an R154 use W58 speed sensors?" might work. - Most likely the R154 and W58 have different lengths...which means at the very least your driveshaft may need to change when you do the swap. - To me, you shouldn't swap with an r154...you should swap with a v160. That way (among other things) you wouldn't need to figure out how to adapt an MKIII driveshaft to an mkiv ... or get a fully custom driveshaft done.
