Rob's C70 T5 AWD

I think that the coupe is so much more elegant than the convertible... Horbury did this so well...

Rob

To clarify... It's fixed now..

Big improvement. My first 'R' clutch was not an 'R' clutch. Power in high gears meant clutch slip...

Rob

Update.

It started in an attempt to replace the vacuum hoses throughout the engine bay. I found the silicone type hose on the outlet side of the turbocharger had a hole burned in the side of it, I also had the slightly ugly pipework on the inlet to the throttle from my NA TB conversion that I wanted to clean up a little.

I decided to buy some silicone hoses to replace all of the rubber stuff. I had heard mixed reviews about reverse intercooler plumbing, some saying it was worthwhile, others saying it was a waste of time. I decided to do it anyway, if nothing else it has allowed slightly larger pipes, less bends, less hoses and it looks much better.

I am not sure if it has made any difference or the improvements i have noticed are more related to the fact that it now has split free pipework. Either way I am happy with the way it goes and am loving the way it looks.

BTW, I temporarily wrapped the spark plug cover to see how it looks, a proper CF one is on its way but may take a little while and this one looks good in the mean time. I have a little more engine bay detailing to do but I reckon it is looking good.

Lookin real good!!! What pipe is that? Alloy painted? And yer black coolant lid is that paint too? Keep an eye on the coolant tank , looks like on the way to splitting and dumping coolant , see if any wreckers has car with a near , clear one maybe? Sort of indicates that the radiator end tank seals are going too if not the plastic hose mounts on it can be brittle too. That mob up your way will build an alloy radiator for us for $7-800 odd , maybe we should do group buy on here and get it cheaper? Not sure what the do888 ones cost from VP Tuning. He has the do888 intercooler I know that much. That burnt hose goes back to the wastegate actuator??

Anyway Rob , fantastic looking car! I wish I had your work ethic! (Well , I do , just can't I guess...)

What psi is that cap? Pretty sure you should have a green 150 rather than the black 75.

Ex850R

Ohh , i didnt know there was a black cap!! YES ! Green is the one , there is a grey one too , not sure what that is but i have one somewhere?

egads (she/her)

There is white also, 100kpa.

Rob

It is the correct spec cap, it is not genuine. The bottle is pretty good, it has no swelling or anything like that but it is stained and I will be getting a nicer one.

The top pipe is exhaust pipe. It is still raw, I haven't painted it or anything yet. I'm not sure if I will make one up out of stainless or aluminium or just paint/powdercoat the steel one...

The radiator was brand new about 3 months before i got it, I found the receipt in the car.

The hose with the burn on it was the main outlet hose on the outlet of the compressor, so was most likely the reason for the performance improvement.

Ex850R

Ohh yeah! The pressure hose without a hole would account for some improvement!

The plastic doesnt swell it gets brittle , lucky for the radiator though! Saves a bit of cash!
The RIP kit sells from most performance volvo places , should make it boost quicker , the old T5 850s had it that way , i think it changed to allow for ageing motors/blocked breathers putting oil residue into the system/intercooler and causing volvo grief.....

The Reverse intercooler plumbing debate is a good one.
The facts really are that MY94 and very early MY95 cars had it standard, but in very cold climates there were issues with frozen throttle bodies and some no-start issues, so it was revised to the messy arrangement that we all got from the middle-ish of 1995 onwards.

This would suggest that the original method of plumbing is probably better.
The reality these days is that as all the cars are getting higher up in the number of kms on them, everything in the engine bay has been through lots of thousands of heat cycles by now, that its all rather ordinary.

Swap over to the RIP and things are instantly a lot better. I'd argue that it is as a result of newer connectors that dont collapse or arent split.
Regardless, if you're changing over, its a good idea to replace it with the RIP setup.

AshDVS

@Rob, if you like, make up another top pipe and send it down. I can drop it in with some powdercoating and send it back.

Rob

Thanks Ash, I may just take you up on that.... unless I am getting my wheels done some time soon and I may be able to sneak it in with them.

I spotted this car
http://ozvolvo.org/discussion/742/gumtree-1994-850-t5-manual-wagon#top
and noticed it was configured that way in a factory looking fashion.

Rob

Next job for the day...

Correct. Being a 94, itd be stock.
interesting car though - manual, 850R front bar and roof spoiler.
My old 1995 850T5 had the later style, non RIP, plumbing.

Tigabu

Jup, looks kinda FUBAR'd

@AshDVS fuxed cos it was annoying me :-*

Rob

Heater core replaced :)

Electric aerial replaced :) Thanks @Ex850R

and picked myself up a set of green injectors :D

Tigabu

Purdy...

Ex850R

Ohh , nice , new! I scored a set of s/h ones I need to find and take for cleaning now that you reminded me , were they local? Is that the Blue tune upgrade?
With your experience a quick H/G job before you do the full upgrade would be easy so perfect time for some port matching and chamber work thatll help those greenies work even better!

AshDVS

I have a decent doc on volvo injector flow rates by part number and colour if you're interested.
Im going to use one of the Nuke fuel rails for mine too.

Ex850R

ORLY! Yes , I am interested , and the cost of a fuel rail too , although I would be better off making one cost wise I imagine....A tune for you as well Ash? Big injectors?

Tigabu

Do love the Nuke gear, yes I do...
