1. No 2. Yes 3. No Easiest to move the rad hose a bit.

Congrats to everyone, it's certainly onwards and upwards at the moment - the club is growing very well.

Well yeah when you're overtaking you can't avoid but just general driving about you/garda won't notice. Plus you can boost without the screamer needing to make a noise, it's only when the wastegate needs to open - so if you push on at half throttle/ 0.5bar it probably won't need to open.

Well if you route the wastegate exhaust back into the main exhaust then you'll hardle notice a difference, if you just leave it as an open ended screamer then obviously it will be louder. Day to day the screamer isn't bad unless you drive like a tit.

An internal wastegate is what a turbo has as standard, (on pretty much all turbos) external is an upgrade which gives better boost control, however you need a modified/new exhaust manifold to fit one.

Thanks, so am I! It is sad to see any good project get broken but I'd say the bonnet has gone to a good home. Thanks Joz, a set of wings like yours next and I'll be happy. The website is speedflowshop.co.uk they have loads of fittings and you can get complete kits with lots of options.

Great to see you straight into another ep, I've a feeling this could turn out awesome!

It's sad to see this but it was asking a lot of the standard internals- you know you're now going to rip it apart and go forged, just admit it!

Time for another update.... I'd been worrying about my oil temp for a while now as it seemed to be higher than it used to be for no reason - I was easily seeing 95+ just cruising on the dual carriageway and then when on the back roads giving it a lil stick it would rise to over 100 pretty quickly, so an oil cooler was required. Handily the girlfriend very kindly got me this for my birthday last month: A speedflow kit complete with mocal thermostat - not the cheapest kit but I wanted one which was good quality, since a leaky connection from a cheap fitting or burst hose could spell disaster for the engine. So a few weekends back I set about fitting it - in the garage due to it being a lovely rainy day!; First I stripped the whole front end off: Then I mocked up the cooler and cut some brackets out of aluminium angle and also a new bonnet stay from a bit of flat bar and fitted them up (with all new stainless bolts- almost every bolt I took off to get the bits stripped was seized or sheared!): Unfortunately thats about as far as I got that day due to this: The sandwich plate wouldn't quite fit due to the power steering bracket, I did anticipate this but thought it may squeeze on as it's not too big a sandwich plate however the main work was done in getting the cooler mocked up. So fast forward a week later and I did this: Attacked the bracket with an angle grinder, not much needed to be taken off, just a slight skim. So with that done I fitted the sandwich plate and hosed up the cooler: The hose lengths I'd specified were just the right length but the intercooler needed to move forward slightly to let the hoses pass behind - I also needed to bend the oil cooler brackets to angle it back away from the cooler, it's certainly a tight fit with the intercooler back on: I've not actually given the car a good enough run yet to check the oil temp but I'm sure it will do the job. At the same time as fitting the cooler I also tidied up the intercooler and fitted some new stainless jubilee clips and wrapped the pipe to the throttle body with some reflective tape as I had noticed that the pipe was touching the radiator hose, you can just see the wrap here: The observant amongst you may have spotted someting else that I've added: Bonnet pins - not for the s bonnet though but a lovely cruise bonnet I got off Shortys now broken (Rip) Cruise kitted glanza! I've always wanted one of these and when I seen Shorty was breaing his V I had to have it, so huge thanks to him. We were both very worried about the postage of this but it got to me in mostly one piece - unfortunately the corners at the windscreen got slightly damaged but they will be repaired eventually. I'd say it still looks awesome fitted though: The only problem with the bonnet is I now definately need to re-paint my rocker cover since you can see it through the vent - but only on sunny days ofcourse! So the exterior of the car is almost perfect in my eyes now - just some wider fenders and wheel spacers to finish it off, but maybe a bit more power is needed before that.....

Very nice diagram - I think it would work on the turbo's too - as you say they act the same under vaccuum. EDIT - The only thing that would concern me (in the first case) is whether the vaccuum from the inlet and hence under the rocker is enough to pull open the check valve and let clean air in - will the whole rocker be under vaccuum due to the inlet, I'm not so sure? The set up is actually the same as the stock setup it pulls the vaccuum thorugh the rocker cover and has a hose onto the efi pipe and obviously works - even though there will also be a slight pull from the throttle body inlet the vaccuum through the rocker must be stronger.

I'm using an hks actuator to hold mine closed, works fine. Bare in mind the turbo will have to come off anyway to fit the new mani though.

Oh kinky! For anyone that hasn't used a clay bar I would highly recommend one - it's amazing the difference they make and the shit they take off the paint that you didn't even notice was there.

I use the bilt hamber clay which you only need to use water with, its easy to use and was only about a tenner.

That's why you ideally would have a second catch can in that line too.

The check valve is needed in the same line as the pcv valve to stop the catch can being pressurised, you don't actually then need the pcv valve (as the new valve will act the same but just 'upstream' of the pcv valve) but it won't do any harm leaving it there. On the pcv line the flow is only into the inlet mani, but the other breather needs to be able to flow both ways so you don't want a check valve here, the only problem will be if you get chatter as this may pressurise the head. Liam the best method is using two catch cans, if everythin was still standard you simply put one can between the outlet from the pcv valve and inlet mani with an additional check valve before the manifold. The second catch can goes between the outlet from the second rocker cover breather into the turbo inlet. Basically if the standard hoses allowed all you would need to do is cut them in half and stick the can in the middle.

I did say on my first post in this topic that two catch cans was the ideal setup. However I now actually know how the stock setup works and why not having the vacuum conected isn't best ie an open line running under the car may pull a vacuum at speed but not sitting on idle stationary plus you won't be pulling through clean air at all. Looks like I'll have to get another catch can unless I can think of a way to maintain the stock setup with a single can. Some coalescer cartridges for inside the cans would be good too.....

This is automotive news how?....

Those parada's have certainly seen some action! Cars looking great now - track slag indeed.

I'm understanding it now that you need the vacuum from the inlet pulling through clean - filtered air from the inlet (with just a breather filter fitted there it may not perform too good as that small filter can get blocked with oil quickly, so this is best routed to the inlet pre turbo) which also pulls through the contaminants into the inlet manifold. This will only happen off throttle, at all other times the breather will be pulling out the contaminants (via the inlet pre turbo if routed this way) not letting the clean air in. So as I say ideally you would have the set up exactly as standard but with a catch can in each line and one additional check/one way valve at the inlet to stop your catch can being pressurised. You've both cleared it up for me anyway.

You can see how Gavin/ enzo_e..., has his setup in the photo above, on the 4efte for the same setup you'll have the catch can in the line from the pcv to the inlet manifold, on the turbo you would need a second one way valve to stop the catch can being pressurised - this won't happen on an na so it's not needed. The second breather can then be linked back into the inlet pre-turbo with just a simple hose. Now what confuses me is nastyrash was saying the catch can was needed before the throttle body not after yet agrees with the set up above where the can is after the throttle body?? I'm thinking a two catch can set up may be the best.... Oh and one way valves can be got off ebay easily, it doesnt need to be an expensive pcv valve, I got a 9mm one way valve for a few quid. -- http://cgi.ebay.co.uk/Fuel-Non-Return-Chec...=item439d503936

You'll want a second one way valve (what the pcv valve is) in between inlet and catch can to not pressurise the catch can, otherwise it's ok.

How very random! I can't think where you would've been but obviously not far from where I live!

It wasn't my car I was talking about-I still have the pcv hooked up as standard and just a filter on the breather. With what your saying I will just put the catch can off the breather then- for now, I may still get a second catch can to collect contaminants after the pcv. I thought the whole point in catch cans was to keep the inlet charge clean, not because of fowling as you say. Interesting!Thanks.

If oil vapour/contaminants come out of the breather would they not also come out the pcv port? EDIT-Since you edited your post. Ok so your saying the best place to have a single catch tank is between the main rocker cover breather and inlet pre turbo? My question above still stands-why does more oil vapour /contaminants come out of the breather port? I've seen catch cans inbetween the inlet and pcv with plenty oil collected?

You will be pressurising the catch tank if its between the stock pcv and inlet, it will probably be ok but ideally you would put another one way valve after the inlet and before the catch tank, but then the stock pcv isn't really doing anything so can be gutted and/or enlarged. The best way imo, is having the catch tank between pcv and inlet with a single one way valve before the catch tank, then another line from the breather on the rocker cover tee'd into the inlet pre turbo with another catch can in this line. The only problem this may have is if you experience turbo chatter as then this pressure through the turbo could actually pressurise the rocker cover but you obviously dont want to fit a one way valve as then it will no longer act as a breather. I'm going to run this setup but with just one catch tank between pcv and inlet (with a second one way valve) and just a straight line from the breather tee'd into the inlet pre turbo.
