what bits would i need to make my own?

With the pound being crap at the moment that won't be far off the price in pounds!!, then you've got shipping and of course import tax. You'll probably be looking at about £500.

i think you will need 3 x 90 bends, a T peice for your bov, a rew straight joints and another Tpeice for the pipe to the idel controll valve

ok nice1 mate im gona give it ago.

anybody made there own and no exactly what i need?

Yeah, thanks thats a great help

Well strictly speaking the reverse piping was the original, but volvo changed it supposedly because in colder/icy weather (in sweden and other cold countries) the cooler air coming from the bottom of the intercooler caused the throttle body/flap to freeze up/ice up. So they swapped the pipes around so that the slightly warmer air from the top of the intercooler went to the TB thus solving the problem.

But since it doesn't get anywhere near as cold in this country (or not often anyway) the reverse IC setup is fine.

to make your own, you need.

? = whatever size pipe you want to use

top turbo to IC top pipe
1 x straight reducer (turbo top - ?)
1 x 90degree (? - ?)
1 x 45degree (? - ?)
1 x 45degree reducer (? - IC top)

bottom IC to throttle body pipe
1 x 90degree reducer (bottom IC - ?)
1 x 45degree (? - ?)
1 x 90degree reducer (? - throttle body)
will need a 19mm T-piece to connect the idle control valve

turbo inlet pipe
1 x 90degree reducer (turbo inlet - ?)
1 x 45degree (? - ?)
will need a 9mm T-piece to connect the PCV (inless running a catch tank) & you'll also need a 40mm collar welding in to fit the MAF sensor

you'll also need about 3metres of pipe & 18 jubilee clips

nice1 mate. i will be using a catch tank. at the mo mine is venting to atmos as it has broken under the manifold so its leaking crap onto the bottom intercooler pipe. but its still fine to drive and i have blocked the hole in the air pipe to the turbo so i will sort that when i get a chance in a few weeeks. should be ok till then

I'm going to order the RIP kit from IPD, Just have to wait for them to get the new style in stock.

**redbaron** · Saturday 3rd January 2009, 18:06

is it really that simple?what about the silicone hoses,are they simply bends or do i need to get special bends made up?

ish, you will need several pieces welding (T-piece for the idle valve, PCV & MAF collar)

nope all brought off the shelf, even all the angled reducers were brought straight off ebay (seller called nicenewcar)

Is there really any noticeable benefit for doing this?.. seems like a lot of hassle (and expense) if there's not.. I've read a few posts on it and am still unclear as some people say it makes a difference and others don't... hmmm..

**zoomungus** · Saturday 3rd January 2009, 20:58

i am so going to this when i get time!

i had the factory reverse flow as standard so can't say if there is a difference between normal, when i upgraded to my own spec pipes i also fitted a modified 960 throttle body which made a huge difference

LOL! - fair enough.. be interesting to see exactly what the difference between the two are though and if there is any benefit to doing it..

**t5 pete** · Saturday 3rd January 2009, 21:30

When i fitted myne the pick up was a bit quicker but nothing much i think the main reason ppl fit this is due to how nice the pipes look
