#1: 205 GTI180 Supercharged Author: 205GTi180, Location: DerbyshirePosted: Thu May 10, 2012 2:08 pm ---- Hi guys. I know this isn't a 206 but since i joined this forum i have had a fair bit of interest in the car, also the development of it.
To cut a long story short, me and a mate originally built this in 2005. It was owned by him, i already had my own 106 track car.
My mate managed to find a fully track prepped 205 shell that only needed an engine. He didn't want to go down the old mi/gti-6 route because he wanted something different. In the end he decided on a 206 GTI 180 (EW10J4S) engine and found 1 that had covered only 500 miles when lifted from the 206. Im fairly certain it was the first 205 with this engine fitted, we contacted various peugeot tuning companies for info and all said it couldn't be done. To start with we had it running on the standard ecu and multiplex wiring which wasn't ideal. We then ditched that and ran it on a omex 100 and carbs (yes thats an engine with variable valve timing and carbs ) It produced a healthy 197 bhp and 155lb/ft, we were over the moon. The smiles soon wore off so its back in the garage for cams, TB's and omex 500. This next setup made 202bhp and 167 lb/ft, not much gain for the money spent but it drove so much better and idled like a standard car.
After a couple of years and plenty of trackdays my mate decided it was time for a house. So much of my own time and effort went into the car i couldn't resist buying it. I was half way through supercharging my 106 at the time and kept at it for another year. Having such a good all round track car i always had doubts in my mind wether the 106 could be a match for the 205, deep down i knew it wouldn't so i decided to break the 106.
My old supercharged 106
The 205
In the past years i have owned the car its had a full respray, a few extra sets off wheels and just general tidy up. It may be a track car but its my aim to keep it mint, the shell was dry stored for a number of years be for my mate bought it so not single bit of rust any where.
How it looked after the respray
At the end of summer 2011 i decided to strip the car down and rebuild everything. That included fitting a few goodies that i kept from breaking the 106.

#3: Re: 205 GTI180 Supercharged Author: 205GTi180, Location: DerbyshirePosted: Thu May 10, 2012 2:19 pm ---- Stripping the car down and mounting the S/C
Making the new Inlet plenum
Custom (removable) strut brace
Once happy with how everything fitted i removed the engine and stripped it down, seam welded the bay and filled all the unused holes in the bulkhead
Sweet mate can't wait for the updates you have planned
Cheers. The S/C conversion is done now so its just a matter of uploading and cathcing up with its current state!

Strip the engine done and please do something with the compression before a rod says hi?
#6: Re: 205 GTI180 Supercharged Author: spike_202, Location: West midsPosted: Thu May 10, 2012 2:27 pm ---- Could I ask a massive favour mate and when you mount your rad in take some pics as I'm hoping to fit the 205 rad in mine and just need some pics of the mounting points and pluming lines as I need to custom pipe it
Strip the engine done and please do something with the compression before a rod says hi?
Im going by the quote in your sig Hi comp and boost has been used for years. By lowering the compression you need more boost to make it back up!!. Yeah i am running standard internals but good mapping and water/meth injection will keep temps down. Also 9 psi of nice clean linear s/c boost is far more effiecent than hot turbo boost dumped in a 3k
At the end of the day these are a fairly cheap engine, im just pushing it to see what its made of.

Im not running a 205 rad. Dont have 1 to take a pic of either. From memory the 206 in/outlets are in the middle top and bottom?. 205 is top right and bottom left.

At least you gave me giggle.......
Yes theoritically you need to build that compression up but the general point is to compress more air into that space than before?
You have no mention of the fueling system, and i personally would like to see the effects on the lifetime of the engine with water added to the combusition chamber.
Yes alcohol may stop the chances of pre ignition, but the pro's just completely outweigh the cons. A STANDARD petrol engine was never designed to withstand alcohol, you may know what your doing but in my eyes
Its a disaster waiting to happen.
And to the note of 'hot boost' at 3k, with the slightly smaller turbine A/R i have chosen the power output may not be amazing, but then again what is for a 1.4? But there will be minimal lag and there is just as much chance as you or i suffering from heat soak.
And as shown by someone from TDI, with a minor modification to the intake system to lower it to 14 degrees he say a 12 percent power increase.
So yeh just saying. I'll go back to my tyre stretch now Last edited by Addaz on Thu May 10, 2012 3:02 pm; edited 1 time in total
#11: Re: 205 GTI180 Supercharged Author: 205GTi180, Location: DerbyshirePosted: Thu May 10, 2012 3:02 pm ---- While i was busy with all the fabrication and bodywork i sent everything away to be blasted and poweder coated. All parts have been re-fitted using stainless bolts
The 206 Gti 180 exhaust manifold is a work of art standard. When we first did the conversion it was running a 2.25" exhaust so thats what size flange we used. Im now changing that for a 2.75" so off with the old and on with the new...
Wrapped
Helix 6 paddle fitted
When we first did the engine conversion i fabricated a small box to hold the gear selctor box. The selector boxes are pretty bulky and i needed more room in the tunnel for the new 2.75" exhaust so raised it up as high as possible
The car doesn't run any of the original instruments so i ripped apart the loom and cut it down to the bare minimum. Managed to fill 2 shopping bags of excess wiring so a good bit a weight off

Yes that is the general point. But why lower the compression to start with when you can make the same power with less boost?. Have you ever driven a low compression engine with no boost??.
Hi comp and boost has been favoured by a lot of top tuning companies for years. You need some good internals and high octane fuel to run it safely but there you go!!.
In an ideal situation i would be running near standard compression forged pistons/rods etc but im willing to find the limit of these engines be for splashing out!.
I'd also like to point out that this is no road car and never will be. The side effects (if any) of water/meth injection aren't likely to cause me any problems be for my engine requires a major overhaul anyway!.

Everytime i see a project like this it makes me want my scooby back. I really miss boost lol.
Good look with it mate
#14: Re: 205 GTI180 Supercharged Author: Schumi, Location: Istanbul / TurkeyPosted: Fri May 11, 2012 12:56 am ---- There is nothing wrong with High Compression Ratio and Boot if your fuel octane enought. IF octane isnt enought you can use water/meth injection kit. And I dont like low comp engines. High Comp with low boost is very sharp and responsible engine.

Point one, why would i need to drive a car with LC and no boost?
And yes the gains will be the same, till a point in which your HC engine pre ignites and the LC engine does not but continues to perform.
Your finding the limit by wasting money? Fantastic, and i will retract my statement of a rod coming out the side as its not 'all' about how strong your internals are, its about the fueling more than anything.
No offence here, but you seem to be the person that slaps on nitrous oxide with no real equation or formula on how much you need, and expect it to work miracles.
And yes HC and boost is used, but when did they ever decide to use standard internals?
