SZ Territory Turbo Conversion

that sucks... warranty work is sometimes a huge pain to chase up

Yep. I supplied the shop a centre only so I'm probably liable for the R & R portion. Will speak to the diff shop early next year and see what they'll agree to pay for. Moreover, I'm hoping the new CW&P isn't rooted as it was a brand new unit. Don't want it whining in 20-40k time, that will f@#$%n piss me off.

Romulus, what offset did you go with on the Simmons FR-c's?

[Romulus]

ET36.

 

Can't find the photos of the brackets unfortunately.

Short update.

 

Had the rattly and clunky Truetrac removed and replaced with a genuine Dana LSD. Car drives heaps nicer. Following up with Motospec to get my money back as the heap of metal is not fit for purpose. We'll see how this progresses over the next short while.

 

Sent the suspension back to Shorkworks for new lower mounts and to revalve the dampers for a softer, more supple ride. Great thing about the Shockwork product is the ability for Brett and the team to revalve the dampers to whatever ride type you want.

 

Machined the rotors all round and fitted new Project Mu pads. IMO the stock Textar Brembo pads didn't like the run in with the Bendix rotors. Been chasing brake shudder since the brake kit upgrade. Fcuked the Brembo pads off and replaced with the PMU's and all shudder is gone. Next time I won't bother with slotted or dimpled rotors, too noisy when braking from moderate to high speed. I prefer a more silent mode of operation when wiping speed off at 200+km/h......

 

Dump pipe and cat have reached the end of their service life, the dump has developed a crack and the cat internals are coming apart. Booked in with Monsta Torque for new X-Force Dump/Cat fitment. Other than that no other issues to note.

interesting that you took out the truetrac and didn't put in a wavetrac...

[Romulus]

The problem with both designs is the inner axle splines are not supported like the stock centre or stock LSD does. You could literally move the inner axle 4-5mm up and down with the truetrac, it felt like a spoon in porridge and this translated to a lot of rumbling and vibration in the driveline between 80-120km/h, most typical cruising speed. The wholesaler is aware of a lot of complaints with the truetrac and driveline backlash and vibration, the problem is Eaton doesn't seem to give a sh*t at the moment.

 

Given the car won't see more than 400-420rwkw on U98 and 500rwkw on E85 (if I ever get around to upgrading the fuel system) the LSD will do the job.

Hi Romulus,

Thanks for going into so much detail about this build.

I'm the owner of PACE Motorsport in Perth (specialising in forced induction motorcycles) but have an employment history of tuning the BA/BF turbo platform some years ago.

Last year I purchased my wife a 2017 SZ Territory with 45k km on the clock with the intention to do almost exactly what you have done to yours, but instead of starting with an NA engine, I purchased a FG mk2 G6ET engine/turbo/fuel/management system (suit conversion).

I'm going to begin this conversion in the near future & was hoping to be able to get in contact with you to discuss some items in more detail.

If this is possible, Please let me know how I can get in contact with you. 

Regards,

Brett

2 months later....bit the bullet and it's now running on E85. I should have done this from the get-go, the engine feels soooo much better. Boost is limited to around 17-18psi as to not max out the Walbro 460 in tank pump.

Such fun rolling along in 3rd and blowing the tyres off at 80+km/h.

 

No cold start issues either

 

Car goes in next week for some maintenance and I'll get Rob to check my road tuning on the dyno.

 

I've also had the Superpro bushes for the control blades and front upper control arms removed and fitted genuine rubber bushes when the revalved suspension came back. It's so much nicer to drive, much more complaint and no annoying suspension squeaks. It was Shockworks recommendation to revert back to the factory bushes as these work best to eliminate NVH. They'll probably need replacing every 30-40k but so be it.

Needs more fuel delivery to take advantage of E85. Boost is capped @ 19psi, made around 455rwkw. Tried running more boost but ran out of fuel at 490rwkw. I need to replace the rear muffler as its choking the engine. A single 3.5" into twin 2.25" was a great idea in theory but it can't cater for the gas flow.
