My long term tidy up!

I think he did use the iso free 2k clear.

I know old school painters never say to 2k over acrylic, but they are the same people that put 10 coats of acrylic on.

Been a minute, transmission is continuing to hold up well but has had limited abuse. I'm ready to pull the trigger just can't decide on who to go with.

Some minor house keeping has taken place replacing the high pressure power steering line. I changed the main o ring a few times but it was the internal o ring on the fitting which had given up.

Unfortunately I have noticed a crack in one of the spokes of the xr8 rim. With the way the roads have been in Sydney lately, I haven't been driving the car much in fear of the rim exploding. Disappointing that old mate hid this from me when selling. Ive found a guy who is confident to repair it just waiting for the right time to get the tyres off, repaired and new tyres fitted. I'm also trying to hunt down decent priced 18 inch rims the clear brembos but not having much luck.

Next up was getting the battery to the boot as finally the 50mm2 cable rocked up fairly tidy install with p clamps and cable ties for back up. The car cranks a little stronger now which is also welcome.

Antz performance turbo side intake went in too. Not sure if I'm set of the massive dose but when cruising around its fine.

Thought I'd use up some of the left over power cable to make a tough engine-body earth cable for the hell of it. Cut it a bit longer the original so it sits a bit nice around the piping.

I also managed to locate some wheels to replace my cracked xr8 18s. Not exactly my style however they were $400 and have Yokohama v105s fitted with atleast 80 to 90% tread, hard to pass up. Fronts needed a 6mm spacer to clear the brakes. Grip is quite impressive.

Very very close to booking in the car somewhere to have the transmissions built. Still undecided on shop. I am capable of doing the r&r myself however don't want to take any chances if issues come up down the track. Wouldn't want a 'you fitted it incorrectly' situation. So looking at the whole r&r, build, tune deal. Really want to send it down the track with some confidence.

If the trans is still holding up then why not get a fark off tune from hell chucked into it to keep it alive? Be cheaper than a new trans.

It slips on the 3-4 full throttle gear changes so is showing signs of being tired. By Holding up I mean it hasn't sent zf all over the princess highway kinda thing

[gaz097]

Did someone say highway

I've finally been getting around to looking at my waste gate actuator. The iwg75 was supplied to me as 12psi. As it stands now I was never able to keep it under 16psi. The car was tuned at 16psi and after I did the head gasket the car over boosted which made me bypass the solenoid and just run spring pressure.

So last night I pulled off the actuator from the bottom of the car by taking the engine mount and engine mount plate it. The e clip was still a pain and once it came out, it touched my shoulder and was never seen again.

So I stripped the actuator and verified that it does actually have a combination of springs that make 12psi.

For the fun of it, I fitted a 10psi spring and put it all back together. On the drive home, it held 10psi all the way like a champ.

The only thing I noticed was the flap arm hits the dump flange stopping the flap from 100% opening however it still looks like it opens a lot.

So why is the 12psi combination making 16psi? Is the port job on the flap not big enough?

I will be doing the job again and fitting a new set of 12psi springs and getting the dump off to grind away the part that it's hitting.

Or should I just go external gate and stop wasting time?

[Puffwagon]

I would just get it retuned with the 10psi combination, as you know it holds that boost level just fine. Turning it up a few psi from there will be a breeze. External wastegate for your application is a waste of time and money.

 

While you're checking stuff, make sure the actuator rod isn't touching the engine mount. They can do that and cause issues.

I was just about to write something just like that.

Talking sense captain puff, thanks. Assuming I re connected the solenoid, how much more would that spring hold you rekon? Having it back around 16psi/400rwkw would be nice.
