2.0 Turbo With 1.9 8v Management?

[pugdamo 111 2 Cars]

Just read a post from a guy on PGAC that he has a 2.0 turbo fitted and he is using the 1.9 inlet and loom,i have considered putting a turbo engine in mine as a mate has bought one and done nothing with it for 12months,and i may be able to get it cheap.

Is running the 8valve inlet and loom possible without killing performance?if so i may consider it some more .

Also would i need the injectors from the 2.0?And what would need to be done with the AFM as the readings would be well out with the turbo engine?

Or would it be worth running it on the 406 management?

Or am i just completely wasting my time with the whole turbo idea?

 

So many questions,im sure ill get pointed in the right direction (probably away from the whole idea )

 

Thanks in advance Damo

I guarantee that won't be the way it's actually running, more likely to be a 1.9 TT setup on a 2.0t, that might work, but a 1.9 GTi NA management will not run a 2.0 turbo engine!

By the sounds of it, the engine is from a 2.0 406, If you buy the engine then run with the correct 406 management. you will have to wire it up properly, but it is worth doing.

Cheers for replies,didnt think it could be that easy,he says its the 2.0 turbo from an XM running 1.9 management.

A friend of mine has a 2.0 406 turbo in his GTI and i think it goes really well,but that is as you say thats running the 406 management.

It is possible run the XU10 engine on XU9 management (DazeMad on here did on a normally aspirated one) but the turbo ecu needs a map sensor to adjust the fuelling, in conjunction with a knock sensor and a lambda etc. It will probably run but not really an optimum setting and runs the risk of over fuelling

I've seen it done, using the stock AFM and a unichip with a 5th injector. It was utter balls and ran like a sack. Proper aftermarket management is the only way to go IMO. (wont even pretend to be impartial as I work for Omex )

If i was you Damo i'd go for a gti6 conversion, after our meet we 'tested' the auto 6 (lol) agianst your mates turbo and it didn't really stand a chance. Unlesss you have the cash to stick an aftermarket ecu on it with better manifold/turbo then i wouldn't bother personally.

Try using the 1.9 8v motronic 1.3 with knock sensor added 161 ecu and 5th injector. will run nice but with some black smoke at low RPM.

I'm sorry but in my eyes any "5th injector" is not a good solution. You may as well have a trained chimp with a bucket of petrol sloshing a bit in when he thinks he should.

Am I using a different engine to all you guys or something, or I either have an especially strong engine or an especially light car!!

 

You talk about the turbo conversions as if they are slow, I just think people don't bother to do the conversion properly and never get them running right.

 

There was a vid a while ago on here of Henry Yorkes turbo cab (i think) on a track behind a gti-6 powered 205 and it was easily as quick in a straight line and much better out of the corners and thats running standard boost as far as I know.

 

I honestly think people just dont bother doing a proper job (which is the reason for this thread!!) and which is why people find them dissapointing.

 

I'm not going to say mine has 2XX bhp as I haven't had it rr'd or that it does 0-60 in whatever but it will get to the rev limiter in 5th in a silly amount of time and the only thing I have ever had a bit of a play with that has been significantly faster is a E60 M5 but since that has 500bhp I think you can let it off. And without a LSD and sticky tyres you just couldnt use much more power, in the wet its useless anyway as it is!

 

Underrated conversion in my opinion.

[dcc 855]

I dont think they are trying to say the turbo conversion is slow. A stock 167bhp engine vrs a stock 150bhp engine, without knowning the torque figures, I would have said both weighing very similar amounts and using a similar gearbox with the same size wheels and tyres, I would expect the higher power engine to pull better.

 

I think both conversion are worth while! after driving both engines in 205's, I prefer the MPG, speed and power of the gti6 engine, and I am sure I am not the only one. However, many prefer the feeling that turbo engines give when on boost, for me, the noise a gti6 makes is far better

I think 150bhp is very conservative for the turbo engine with a 2.5" exhaust, decent intercooler and piping and decent inlet system.

 

Plus with the boost turned up and the fueling tweaked to match I would say there is no comparison between the two. To get the same power from a gti-6 is quite a bit more involved and expensive - though to get big power form the turbo engine is just as expensive.

 

Its the torque that makes the difference when in normal driving and the 2.0 turbo has a lot compared to the gti-6.

 

Anyways I'm not trying to turn this into a one is better than the other cos they aren't, just different, just that how you phrased that you prefer the power of a gti-6 to a turbo tells me that you havent been in one that is running properly as I have been in both and in terms of 'feeling' fast the turbo wins everytime.

 

The gti-6 is smooth and relatively linear so doesn't 'feel' as fast as perhaps it is whereas the turbo is the complete opposite, it feels quicker than it is - relatively speaking.

 

I've got a cam to go in mine and then it will be set up on the rolling road, I am then going to have a go on the 1/4 mile so we can have a proper comparison then as a I know quite a few gti-6's have been down the qtr, I would hope low 14's to be honest if I can get decent traction...

The only thing i can think of that would have affected this particular turbo engine was it was running a td gearbox. I'm not saying it was slow (i've considered the conversion many times myself), in 2nd gear it was just about there but as soon as the gti6 (on 1.6 box) went into 3rd it started to pull away comfortably well into 5th gear. Also this particular 6 engine feels pretty rapid, maybe its a good 'un.

Bales is talking a lot of sense in that a 2.0 Turbo is underrated as there are a lot of shoddy conversions out there. I only know of a handful of people running turbo 205's in the UK as most people get put off by "the manifold is poor" or the "turbo is a bad design" comments littered around the forum if you search. Mine works, mine is standard 0.5 bar boost and it is quick enough without the noise, wear and hassle of a high revving, shell spinning and surging Mi16!!

 

This was the video Bales was referring to

. I found the test pretty interesting on track as I though I would get nailled! I pulled in to let Carl past as he had been on my tail for a few laps so assumed I was holding him up and he was being polite. It was just that we were evenly matched. However I know there is quite a lot more in mine if I put it on a proper ECU as it is running on 2.0 mgmt on a 1.9 block etc

[danpug 1]

Are you not sorely tempted to stick it on an aftermarket ecu?! Should unleash a good few bhp.

[NickMi 0]

Hi Guys,

 

I ran a 2.0 turbo engine with 1.9 LE Management. I just opened up the inlet ports in the head to accept the maniflod and fiitted a bleed valve. Problem being that it ran very rich at idle and low revs, On full boost the fueling could not cope (Lean out) and the ignition timing is totally wrong for the engine. The end result was complete meltdown of the pistons.

It might appear to be a cheap and easy option but i can say first hand it wont work correctly.

 

Stand alone EM is the only way in my eyes

[pugdamo 111 2 Cars]

Thanks for all your replies,i didnt think it would be that simple.

 

Nickmi thats exactly what he said he did,matched the inlet ports to the manifold,and ran the 1.9 management,at least i know it can be done but isnt worth the hassle.

 

Cheers all

Very, but I have had the entire engine bay reloomed anyway and rerouted through the bulkhead so it is in perfect condition. Also more power would mean a diff too in order to deliver it and it is quick enough anyway. I only really have any issues at 100+ speeds. It passes cat emission tests fine on its MOT so the MAP, knock and lambda sensor must be sorting the majority out.
