Haven't been on here in years always preferd this place to RTOC, sad to see so much spam on here i don't mind spending some time clearing it up if an admin can give me the power to do it. There is a lot of good info still saved within these boards its a shame to see it wasted.

So whats the real deal with reliability then. as i say i do about 20k per year, currently have a company  but considering a old 5 am i mad LOL

Seriosuly tho im willing to throw some cash at one of these as they are like my childhood dream car

Put it this way i have been looking at audi s4's and e46 m3's if you want to know what kind of budget i have to work with. however i don't want to spend that kind of money on a 5

BUT i would be happy to spend up to  around 4k, including buying and making it reliable.

What is the best way to make one of these reliable? from what i can recall it was headgaskets that used to blow due to incorrectly set up engines. is there anyway at all to make them truly reliable?  im willing to spend cash to do this. but the last thing i want to to spend cash and it brake down all the time after and end up as a money pit. but everytime i look at one i just want to buy one lol

Well its been a long time since i owned a gt turbo! i only had mine for a few months before i sold it due to money issues. since then i have been driving all sorts of modern cars and found they just don't give me the same kick that the old skool stuff used too.

The GT turbo is one of these childhood dream car's of mine, i would love to get one again but im worried about reliability, I don't mind spending a couple of grand on the engine if i can build something reliabl.

Im completly out of touch with these cars now, would i be stupid to consider one of these as a daily car? 20k miles a year? like i say im willing to spend money to rebuild the engine if i can make it last and be reliable, i would want around 200hp aswell.

any advice guys?

sounds like someone has previously threaded a spark plug and replaced with a bigger threated one.

as for black smoke turbo oil seals could be on the way out or valve stem seals, maby evern piston rings. do a compression test on the head

Who ever is claming dump valves are useless and a gimick needs to stop giving out false information.

I could say the same to the "text book quoters" on here.

What I will say to some people though is go and get some experience yourselves, before quoting what Tom, Dick, or Harry has told you :)

its nothing to do with text boot quotes anyone mechanicly minded with commen sense knows what a dump valve is for .dump valves are beneficial on higher boosting engines.
recirculating dump valves are fitted by manufacturers, and not to air ones as customers would compplain.
a dump valve is the best way to reduce thrusting within a turbo and essential to aid turbo life.
some are just too noisy, i have one on my r5 at 16 psi had one on my rs turbo and evo1 and it helps spool up when giving it the beans between gear changes. the turbo stalls noticeably on my r5 at 16 psi with out a dv
why do you think , they are fitted to all modern turbo cars?? .

this is no text book crap or an opinion this is fact.

lol ktec recon it helps....

Why do you think they say that?  Could it have anything to do with the fact that they sell (and therefore make money) them  :wink:

What happens when you remove all the "unused" boost from the system?  When you put your foot back down you have to wait for the system to fill up again before the engine can get any boost, thus increasing turbo lag.

As has been said, gtt's don't require dump valves.  They were not designed to be used with them, and run better without them.

Here's a little story about how dump valves came about:

Back in the 80's, Audi were producing turbocharged cars that gave off that "fluttering" sound whenever the throttle was closed.  It wasn't loud, but it was noticeable.  Now not every member of Joe Public wants their car to be making funny noises all the time, and not many of them knew what it was.  So a lot of customers were taking their nice new cars back to Audi with this "problem".  

Audi were getting a bit bored of trying to explain that everything was fine every five minutes, so they came up with this valve that prevented the unused boost going back through the turbo when the throttle was closed, and therefore stopped the fluttering noise.  Ta the, happy customers once again  8)

lol what a load of bs audi did not desgin the dump valve lmao if what you just said was correct the customers would be flutter free BUT now they have to hear pshhhhhhhhhh! instead?

Dump valves DO benifit engines, on a standard 5 running low boost it wont have much if any benifit due to such low boost but on higher boost it will have benifits depending on boost

basicaly when the turbo is blowing and throttle is open its pumping  air  into the carb nice and easily, now when you come off the throttle and the throttle closes the air has nowhere to go and will build up pressure between the carb top and the turbo, this back pressure has NOWHERE to go, the turbo cant keep pumping more air into a dead end or the boost pipes will blow out! the only place it can  go is back threw the turbo (making the flutter) whlie this is happening the turbo is still wanting to spin normaly the other way but this back pressure is slowing it down and putting strain on it. with a dump valve when you come off the throttle as soon as the back pressure builds up the dump valves dumps the air out enabling the turbo to KEEP spinning thuss reducing anylagg as when you put you foot back down the turbos still spinning nicely.

If dump valves had no benifit why do new cars have them? vw seat audi volvo all have rdump valves.
