I have noticed in the engine pic thread that some of you guys run with ss braided boost side vac lines like off the banjo bolt and off the bov. Is this necessary when running a larger turbo on 18psi. Or are Lindseys vac lines ok? Where did you get those ss lines from? Thanks

It's nice to do, but certainly not necessary in any case. Lindsey's vacuum line kit works just fine.

My Lindsey vac lnes split on three occasions on different sections, maybe it was a bad extrusion who knows. The SFR ones have a thicker wall and if I had to choose, SFR would be the one to go for.

PS, you dont really need the braided line... I have some but thats for fuel and the oil catch can. I may do others later but it would be for bling factor.

heh, alright. But for the money, Im going for the Lindsey kit. Thanks guys.

Yeah I got the LR kit cos it was the cheapest price too. I am sure most people dont have any problem with it. After taking the intake off 4 times to check why my car was running like crap means I will pay a little more

PS You can go down to your local hose and coupling store and pick up some extruded hose for around $2 a metre. At least thats how much it costs here.

That is why my hoses split in the first place because of the PO

lol

I actually had some extruded at work Our chemists are amongst the words best...

world's best, even! hah!

i've got the lindsey vac kit. after thinking it felt and looked a bit weak, i got bored one day and replaced all the factory lines with it anyway. don't seem to have any problems...well no new ones. still get 18inHg at idle, and a hunting idle. i think my ISV is borked...when i disable it the idle is solid as a rock, soon as i reenable it, it's all over the place.

Don't use vacuum lines for boost. Keep them the roughly the same size as stock. So the banjo-bolt to boost-controller to wastegate-line should be about 10-12mm OD. Generic 1/4" ID, 3/8" OD fuel-line works well. Flexible vacuum lines can split like some people mentioned, and the expansion and contractions they go through as the manual-boost controller open & closes to regulate boost causes slower wastegate opening times. You end up with lazier boost -control.

You sold your 88 951 to a Kiwi??? sweet!

facboy

not just any kiwi! *the* kiwi!

he turned it into a Turbo Cup and raced it in the Classic Adelaide. unfortunately he was beset by mechanical problems . but he did rebuild the car, so hopefully it wasn't anything that was my fault.

JR is amazing in the leopard 911 Turbo... He wins the NZ targa a lot in it.
