#1: Le Bebé GTI180/RC Author: lrc_toto, Location: Sofia/BulgariaPosted: Fri Jan 31, 2014 3:08 pm ---- Hi everyone,
as I'm heading towards finishing my build I thought I'd share it with the community here.
The car is a 1999 206 GTI 138 sans multiplex. I have owned the car since 2010 and until last year the car was 100% stock. At first the idea was only to swap the inlet and exhaust manifolds from the GTI180, however I decided to go a bit further.
Please, take into account this is a daily, street driven car occasionally used at track days, so the extent of the build only goes so far (for now). In time, hopefully the car will develop further.
At the last TA session last season (only modifications at the time: KW V1, CompBrake CNC fixed spherical bearing top mounts and EXTREME stainless steel exhaust system):
Last year I baselined the car 100% stock before any interventions took place and the result was 116WHP and 157WNM. This was recorded on a Mustang MD-AWD-500-SE dyno.
What we've noticed is that out of the factory the car comes leaned out a bit (still very safe though). I'm currently running stock cams and ECU at this stage. Baseline to tune plot comparison should be interesting when the car is done.
Difference between Dell'Orto TB and the OEM unit
RACE_FACE Fuel rail with GTI180 injectors fitted
Oil dipstick powder coated
AEM FPR
Marshall shock proof FP gauge
CompBrake CNC fixed spherical bearing top mounts
GTI180 Exhaust manifold (sandblasted)
Head is assembled with the valves in place
There is still some work left and I'm still waiting on a couple of parts, but hopefully the car will be finished by the end of next week. I will post the results after the modifications as soon as we start the car and map it. I believe this pretty much covers all mods to the best of my memory. If I remember anything I've missed I'll be sure to add it on here. If you have any questions, please don't hesitate to ask.
Stay tuned for more info and pics Last edited by lrc_toto on Fri Jan 31, 2014 3:34 pm; edited 1 time in total

#4: Re: Le Bebé GTI180/RC Author: usher, Location: northallertonPosted: Sat Feb 01, 2014 1:46 pm ---- nice to see another 206 being modded for speed, is that rr printout without a re-map
#5: Re: Le Bebé GTI180/RC Author: lrc_toto, Location: Sofia/BulgariaPosted: Sun Feb 02, 2014 12:56 am ---- Cheers lads,
@usher yes, completely stock. The graph hasn't been touched.
#6: Re: Le Bebé GTI180/RC Author: usher, Location: northallertonPosted: Sun Feb 02, 2014 2:03 am ---- That explains it had a look on mine with cam's and a remap I got 120whp so after the map you should get a good gain. I'm looking at the 180 inlet but can't find accurate results on gains for that alone. Itbs are still a possibility
#7: Re: Le Bebé GTI180/RC Author: lrc_toto, Location: Sofia/BulgariaPosted: Sun Feb 02, 2014 11:33 pm ---- That's strange!?! Only 4WHP difference and you had cams and a remap? Did you baseline it before the cams and remap? What were your mods at the time? What dyno was it?
Keep in mind this car was absolutely stock when measured at the dyno (stock exhaust, cat, stock intake, regular petrol, etc).
The GTI180 inlet manifold alone won't make much of a difference. Needless to say, head work is needed for bigger gains as the stock one presents some noticeable restrictions.
For real gains with ITBs you will need a stand-alone ECU.
EXTREME Custom 2.5inch stainless steel exhaust system

#8: Re: Le Bebé GTI180/RC Author: usher, Location: northallertonPosted: Sun Feb 02, 2014 11:46 pm ---- the cams i have are a re-profile so nothing extreme, i had exhaust manifold, induction kit and port and polished throttle body at the time and gained 12 bhp on the re map engine power
#9: Re: Le Bebé GTI180/RC Author: lrc_toto, Location: Sofia/BulgariaPosted: Tue May 20, 2014 7:50 am ---- Update.
The car has been ready for some time now. However, lack of free time postponed the dyno session a bit. Last week I went to the dyno.
The results were 135WHP or ~162HP ATFW.
After swapping the GTI180 B&P inlet and exhaust manifolds, stage 2+ head, 2.75inch TB and Megasquirt Hybrid ECU the net gain is 20WHP. Stock cams, stock compression.
Some believed that the big TB will make the car laggy and difficult to drive as a daily but that's not true. Better driveability than stock, dare I say it. Engine response has improved greatly.
I still need to lower the intake filter as it is soaking a lot of heat from the engine. The need for a LSD diff is more noticeable now.
Also, I am very happy with the GTI180 gearbox mechanism. No more missing 2nd gear. Absolutely different feel.

#11: Re: Le Bebé GTI180/RC Author: jonsully, Location: irelandPosted: Wed May 21, 2014 7:27 am ---- great job i like those engine mods!!what was the cost of them?
#12: Re: Le Bebé GTI180/RC Author: heyziq, Location: MalaysiaPosted: Sat May 24, 2014 10:29 am ---- nice!
#13: Re: Le Bebé GTI180/RC Author: lrc_toto, Location: Sofia/BulgariaPosted: Sun Jun 15, 2014 1:10 pm ---- @jonsully, I don't want to say what the cost of the engine mods was as I think many people here spending big £ on their cars won't be happy and will get demotivated
just to put things into perspective the following:
If there ever was a contest BHP gained per £ spent I will win quite easily
#14: Re: Le Bebé GTI180/RC Author: existenz, Posted: Sun Jun 15, 2014 1:30 pm ---- Are the Compbrake top mounts easy to fit ?
There seem to be some problems on the 106 and 306 model, but from what I've seen they are just fine on a 206. Thinking about getting them too. Did you modify them to fit the KWs ?
#15: Re: Le Bebé GTI180/RC Author: lrc_toto, Location: Sofia/BulgariaPosted: Sun Jun 15, 2014 5:20 pm ---- The CompBrake top mounts for the 206 are a direct fit and quite easy to install. One of the few things that really are "plug&play" for the 206 in my experience. I'm very happy with them.
