  1. That is fair enough all though I doubt if the oil that screws the gearboxs up but the cheaper materials they use.

    But I do agree with the sdi being old school therefore rules don't apply. I don't know which gearbox the sdi runs but the 02j box is much much better than the one fitted to the 1.4 sports.

    I'd probably do the same with the sdi but use the vw stuff with the 02j.

  2. Sorry I meant stick with the vw stuff. I'm not a fan of changing viscosity in gearboxes. Viscosity is only one part of it. I can remember on another car I had people where using just whatever but GL5 was damaging the syncros some how and it should have only ever been used with GL4.

    An extreme example but I personally just think stick with the vw stuff it's cheap for what it is anyways.

  3. Depends what you consider easy. If you want the least permanent option, I would remove the back box then use a piece of extension pipe with some universal exhaust clamps. I forget the diameter of the Lupo but I dunno it'll be something like 40mm to 45mm somewhere around there. Buy a couple, they're pennies from Euro Car Parts, then fit the straight pipe, clamp it and then put a line of gun gum or silicone sealant around the join.

    LOL, well yes, but picking something like an S2000 as your tuning car isn't the same as picking your 2.0 litre VW Cabriolet is it?

    It's all the same really. I know what your saying but if you can get air in and out faster and make a bigger bang with more fuel it's all the same. Even simple stuff like egrs on tdi's will cripple them. Envision, noise, cost and legislation and laws stop cars being what they should be like really.

  4. Some yes.

    Your points mostly apply to turbo cars imo. I doubt you'd see a noticeable gain on a 2.0 N/A vehicle.

    You never seen a k20 or an F20C :tongueout:

    Your right but there is always exceptions to the rule. Most OEM's as said are trying to keep everyone happy but most cars can be improved upon quite easily.

    Either way these tdi's aren't tuned like petrol turbos are.

  5. I have been under the car today for the first time.

    I spotted the gearbox fill hole. Any idea what size Allen key is needed to undo it?

    I couldn't however spot an obvious drain hole. Any clues as to where it is?

    Don't use a allen key lol you will never get it done. Use a hex with a breaker bar. Try to spray it with some proper penetration fluid first though. Also don't undo the bottom one until you have undone the top one. If you open the bottom one and can't get the top one undone you got a useless car on your hands.

  6. Ahh, yes, but you're talking about a guy who's pipe was actually damaged. My point is, fit an aftermarket big bore exhaust to something like an Evo 8 and I just don't see you getting huge benefits. These cars are highly tuned from the manufacturer, why would they skimp out on something like an exhaust?

    Well because most of these cars come from Japan and they have strict laws about noise and emmisons. The FQ's are jdm cars but modded by Mitsu UK with bigger hks exhaust etc etc. that's the only way to get to 360+. Cars are built to a cost. All of them from a lupo to a maybach. Profit is their game and they would cut corners where possible. Why aren't exhausts made of stainless steel?

  7. I've heard "pulsing" is quite important on N/A's. On turbos reduce any restriction IMO better and faster spool up.

    The point I'm trying to make is petrol turbo tuning is not diesel turbo tuning. Petrol N/A tuning isn't turbo diesel tuning.

    Skezza I'll maybe agree for N/A cars but not for turbos. OEM's want a nice sound nothing too loud. Wack a huge pipe in and do some other mods and the car will spool faster, make more power and be more responsive. A guy I know had an evo. Running 400ish bhp. One day it just started running pants. Turns out the pipe had gotten squashed and was restricting flow!

  8. Filters can make a difference especially when tuning higher performance cars no doubt, but only on petrols.

    Diesels are designed to run lean. I can bet you any money my filter on my 1.4 tdi is bigger than the one on your 1.8t (not a contest just trying to explain). I get that when your running a petrol car and you start pushing the bhp a *properly* designed intake can net you power. I get that but not on the tdi IMO. The filter on this car is the roughly the same size as a 6 cylinder 330d engine. Remember diesels run lean and fill with air each stroke so it's using a hell of a lot more air than a petrol will. No throttle body on diesels.

    Secondly putting on an intercooler will help temps but remember how little the turbo on the tdi is. On the 1.9tdi it's a great idea. Even a slightly larger on the 1.4 causes big lag. That tiny turbo can't cope with it.

    Lastly flip flip thinks it's exactly like his r32 which it isn't. " it worked on that so it will work on this". Nope sorry. If you don't want my advice I want give it actually I probably won't bother anymore since you don't get it. You think diesels have lambda sensors that shows how much you don't understand these engines but it's your time and money crack on. I'll be watching for the lulz.

  9. I never got a chance to if the intercooler kit yet but I have experimented with spraying it with water and if does 100% work.

    Lol that's great. I didn't notice much of a difference in mind but I've been running 2 stroke with mine for a while.

    It's always the way though you get more results from a badly treated engine.

  10. I don't know if it is for the turbo per say but I'm sure that is one the aspects of it heat and sheer force. I'm sure it was to do with the cams as they control the injectors but need really good oil to stop them ground down. But don't quote me on that.

    Also you can use the newer oil if you can get it 506 or 507 in the pd but it's usually more expensive.

    Also remember the cp4l codes that gets you £5,£10 or £15 off.

  11. They'll be tight but they'd probably fit I reckon. That said, if they don't fit, taking it to a shop and having it done properly would be important imo. You'll end up with them not sitting right otherwise.

    That is a little contentious. Some people say the central bore is only there to line it up and others say it's a load bearing part and it needs to be spot on. I personally don't agree as most spigot rings are plastic but it depends on what you believe.

    I personally think the nuts or lugs take the weight therefore bore it with something and stick a spigot in as silver says.

  12. you risk hydraulicing your engine if you enter anything deeper than a puddle

    Not true, try doing a water decarbonisation. You spray a crap ton of water in with no ill effects, plus it's got a hell of a way to go. But getting your filter soaked with water wont help performance.

    Like this :)

    Super lol where do you think the filter on the tdi is? You know best though.

    If you're going to play with the intake your best bang for the buck is to improve the intercooler either a bigger one or perhaps a water spray / cooling fan. Taking any restriction out of the intake isn't going to buy you much. Diesels are fuel limited engines anyway they always run excess air.

    Water spray is 100% the way to go. Intercooler will make the car laggier due to the larger size. The turbo is only small. But your 100% right in the way diesels work. The filter is massive on these tiny engines.
