Thanks for the kind words mate! how is yours all running? To give an update on the car quiet a lot has happened since these videos were filmed. I converted it to a 6 speed manual and its now running just shy of 350rwkw on 14psi. I found that by the time i was doing those mods to the car youtube had become so saturated with 1000hp barra builds that it seemed there was little desire for content like mine anymore where as when i started there was very little content on conversions. I haven't really got any car projects going at the moment but if i end up doing anything unique again that i feel will help people if i upload it'll appear!

The 2-3 shift really seems to be slow in these transmissions. What ever it is that engages the gear be it a band or clutches just doesnt seem to bite like 1st-2nd does

you can use an external boost controller you just have to get the car tuned to suit. I prefer using the factory boost control though because it gives the tuner far greater control when tuning. For what its worth this cars now running 340rwkw on 14psi and the factory boost control is working perfectly

I've got another video on the channel about doing a basic overhaul on the diff. Biggest issue you'll run into is changing the diff gears. It's easy to set the backlash and preload with the screw adjusters but you'll likely have to change the pinion depth which is set by shims. Unless you have a mate that works at a diff shop that can sling you an assortment of shims to try you really need access to a lathe and machine up shims or some other method. I'm sure there's places you can buy them but any i've found have been quiet expensive

I've heard feedback from a few now that it doesn't work on the Au's which is a shame as i thought it would have

Thanks mate, so far so good with the engine. It's done 20,000ks now and is pushing 340rwkw

You're dead right i definitely made a mistake there. I have no idea what happened to end up with that result. Its a shame about the ute diff, i actually had the solid axle version of this diff apart out of my fg ute earlier this year. It wasn't a full rebuild but i had to remove the center to change the carier bearings and the lsd friction plates so sort a clunk it had on takeoff. Sadly i didn't film it.

Thanks mate! i think mostly just because my videos are long so they don't really suit casual watching.

Keep it up. Them long vids reveal a lot of detail to help get the job done right. Appreciate it much....

@@xbgtfella Thanks mate, I appreciate it!

Pretty easy job, not sure what car you're doing it on but if its a ba onwards check how tightly the shift cable clips on. If its loose buy a replacement bushing kit off ebay. Once you disturb them they have a tendency to fall off and stop the shifter working if they're already worn when you remove them

Thanks mate!

no problems!

I haven't played with the s5 solenoid in the tune to see exactly what you can do. I actually no longer own any btr 4 speeds anymore, i've since converted the car to a 6 speed manual so i stopped experimenting. This just changes the base pressure of the solenoid and the tune still varies it resulting in the pressure being higher across the board. Changing it in the tune would have a similar effect but I'm unsure if you can adjust the solenoid as drastically in the tune as you can mechanically, you could definitely do both in combination as well but there would have to be a limit before things break. What i had planned to do next is fit an electronic shift kit and wire it into a boost pressure switch to allow the auto to function as normal and then engage the shift kit over a set boost pressure such as 6psi which would help retain shift quality off boost. I also have purchased pcmtec since filming this and have had a brief look at the tables available for the btr. They're hard to understand but it looks like it is quiet possible there is a lot more tunability besides just shift pressure that could help these boxes last.

Hey Mate, i haven't used one sorry. I assume you're referring to their trutrac style clones? i did look into them when i rebuilt this and couldn't find much info except for a forum post of a few guys saying they were ok but not as strong as the proper eaton units.

Depends what you like doing i guess. I've built these engines, tracked them and owned and maintained many intechs and barra's over the years with easy over 1millions kms combined across all cars while they've been in my care, i know these cars inside and out. Both great engines that have their own share of unique issues. I have my reasons why i prefer the barra but also just enjoy modifying and tinkering with things. All comes down to what you like and how you intend to drive the car really. But i agree, its not really worth it doing the swap stock intech vs stock barra as the gains are minimal.
