Damo's first ever v70 t5 build thread

Hi and Welcome to the forum. Nice looking V70 T5 buy the way ( i have a silver one), your understanding of jap go fast bits will translate here fine.Ther...

A shitty old walkway, paper mill, getting it hot enough and burning out impurities with oxy first then big ole Miller Synchrowave 250 TIG to lay one over existing welds that all broke , looks like mig welding not penetrated. Only trouble is Miller has some fault and blows 32A circuit on main board. Sparky in the area so he is busy...

The Rig!

This package of goodness is underway care of ash.

For those interested, here's a link to a couple of 0-100 runs with the new exhaust on.

Interestingly, the bad idling seems to have gone since the new exhaust went on.

Given that there was effectively a v with a dead end, its possible I guess that in peak hour stationary traffic, the exhaust gas velocity was so slow that the 'v' was causing some sort of issue with the 2nd o2 sensor.

It could possibly be that it just hasn't happened again since, but I'm starting to suspect that these emu's maybe very sensitive to their o2 sensors.

Will keep everyone updated if this changes. I'll still do the fuel pump relay and the egr job though.

Ex850R

The sensors are old.

You can test them.

Damo

I probably will, but that can wait if it no longer happens.

The last full tank of fuel it didn't have any issues and given it would blow black smoke then white, idle rough die but restart, badly sometimes, it could have been the o2 sensor getting a bad reading.

In any case, I have the fuel pump relay coming and will do the pcv system next.

good lord they let anyone in here..... :D

hope its going well mate, it looks lovely. wish my mate had bought it hahaha

Yeww ,

Where's your thread on here then?? And did I read you had a tune tool somewhere?

Damo

I've reduced the performance somewhat today

Damo

Not much to report except that she's still stalling randomly but not as bad as before. The fuel pump relay is however in one of these boxes

Along with other goodies from @AshDVS

And I also grabbed some toys from golebys!

Damo

Hey all, can you show me where you put the t piece for your boost reference for the boost guage on you t5s ?

I teed the line out from the intake manifold which is what the online guides said but I am only getting vacuum to 2psi. There's no leak on the boost guage line and the car is driving fine. Do I need to t the turbo outlet to tcv box instead?

Thanks

jamesinc

@Damo any vac line that's referenced to the inlet manifold should give you a fairly accurate reading, maybe you have a vac leak? Do you have a photo of where you teed it in?

Damo

Thanks James, that's what I thought. Here's a pic of where I added the tee.

Damo

Hold up

This is probably a leak

Yup

Where does this line go that had the split pipe anyway? Fpr ?

Also what's this Bosch valve and can I use this line instead?

Ex850R

Geez that's a mess......

Get new hose for everything and pull out the bolt, reconnect the Bosch thing, you are pushing shit uphill with all that fuckery someone did there.......

The past photo is the vacuum tree just pull one of thoes 3 caps off and use the port for any vacuum boost well that's where my boost gauge is plumbed into

TL_V70

Last photo I ment

Damo

Thanks guys, just replaced all those lines. They all fell apart. Is it fuel pressure regulator? There's so many fucking lines to solenoids or pressure sensors it's a bit of a rigmarole!

Test drive time

TL_V70

The hard metal line in the first photo that comes out of the manifold that runs up the end of the fuel injector rail with the fuel line into the rail goes down to the FPR next to the steering rack on the driver's side. The bush valve is the idle control stepper motor That split hose with the check valve goes either to the brake booster or I think down to the back of the turbo intake pipe

The line where you put your white plastic T peice goes to the evap purge valve located on the top of the rad shroud looks like this then goes down to the charcoal canister under the bumper

Thanks everyone. Driving so good right now, I don't think I was getting full boost before, the car is transformed with an indicated 10psi, I'm very very happy! Need to do wiring next and will actually install the ipd boost guage which is in the boxes I haven't opened as yet. ?

I've also installed a manual boost controller on the line between the tcv and the wastegate diaphragm and gave it a small crack.

With no bleed I was seeing 7/8psi and with it slightly cracked open I've got 10psi. That's enough until I get the intercooler and hard pipes and a wideband on her.

To also add to it. Mine is also the same since it's just an R of the same year.

The only extra line I'm running (at the moment) is a boost gauge. My boost gauge line is just from the plastic tree where I removed one cap (same as what @TL_V70 said)
