What tuning tips would you offer to a Peugeot 205 owner. It is the 1.6 GTi model and so has decent brakes and suspension.

I have a few ideas myself but really want to see what suggestions you guys come up with.
 
Yup, definatly go with the MI 16 engine with a 206. My firend (who still actually has the car) has the 2.0 16v engine but has been tuned to 179bhp. It has fast road cams, uprated conrods, pistons and all nessecery bolts etc. Csutom made inle manifold (as the original fouled the radiator) interior completely stripped, roll cage, adjustable gas shocks with eibach pro sport springs plus a few other goodies. The brakes are exactly the same as they originally were as he found that due to the light weight, the car kept locking up with bigger brakes, so the originals were used with uprated Wilwood pads and bobs ya uncle.

It's absolute beast and the entire conversion was done on a budget of £2000. The most expensive part was the inlet manifold beleive or not as that had to be made completly custome.

Definatly the way to go with these small hot hatches ;)
 
That was defineately along the lines I was thinking. I've seen conversion kits around that provide the mounts and manifold.

Of the 1.6 and 1.9 would you say there was much difference between them? Have you ever driven both? I've only had a short go in a 1.6 and that seemed quick enough to me.

How tunable are the MI16 engines then? Is 200 around the upper limit?
 
Anywhere between 200 and 250bhp is about the highest I've seen most 2.0 16v normally asperated engines, but then I have seen a couple over that mark that have used a progressive NOS system with twin 45 webbers or throttle boddies and of corse a LSD to help keep the power down a bit lol.

As far as differences, I can't tell you exactly as i've only had a little go and not owned either, I do know that the 1.9 has slightly bigger brakes where as the 1.6 had disks on the front and drums on the back, and the 1.9 had 1" bigger wheels. So for how cheap the 2 are it would definatly be worth gettin the 1.6. Then there were other differences such as a half leather as an option on the 1.9 etc.

Performance wise with original engines were 105bhp from the 1.6 and then in 1987 were fitted with acylinder head and valves from the 1.9 and then produced 115bhp. The 1.9 produced 130bhp but was then knocked down on later models to 122bhp due to a catalytic converter being fitted.

So it really depends on what path you want to take. To be fair I would go for the 1.6 as you will be uprating the brakes and suspension anyway, so may aswell save money and get the cheaper of the 2 ;)

I've drove both and the 1.9 is by far the best in my honest opinion. And tuning an Mi16 depends on the size of your wallet cause they can go to stupid power......:D
 
1.6 they had to ditch because of emissions regs,

still a good engine though. more revvy than the 1.9

you can stick to it if you want but if you do go for an engine swap then I know some people who would love to have your old engine off you

my last car was a 1.6 gti and i wish i never sold her now! although the barkes where very good i found that the standard pads were useless once they had warmed up, so if u plan on drivin the c ar hard i sugest a good pad upgrade to help u stop, i once had mine so hot that i had to use the handbrake when i pulled over on a slight downwards hill, the pads just had nothing left and io had to wait for them to cool down (about a hour) before driving home.... although the smoke pouring off hem was impressive:)
a good set of springs and dampers on the front with a damper upgrade on the rear and you will feel a huge difference:) i never lowered the rear on mind as every time i started to attept so something came up, but i was more than happy with the wa the car handled, so if u lower the rar then let me know what u think.

as for differneces between the 1.6 and the 1.9 the only difference to the engine is the bottom end, and then nth rear brakes are disks not drums on the 1.9, although the hill climbers tend to prefer the drums as the find the hanbrakes are stronger...
the 1.9 is known for being more torqy where as the 1.6 is more revvy:)

i always wanted to go balls out and try and make another 205 t16:)
 
.I have a pdf that explains everything if you want it....[/quote]

could you please send me this pdf cause iam a new 205 user and iam in need to it.

my msn messenger is abdo7@msn.com
 
i had a 205 1.9gti and lowered the rear beam on her, it was great, (i changed the bearings etc at the same time) - difference was unbelievable on the handling (had Koni's all round as well)
 
Hi all,

i need some assistance on how to rectify a rev counter on peugeot 206.

On idle it tends to move backwards reading between 72 - 50.once the engine is switched off the idle needl points on 50 and not 0 as it should be.

The engine running is smooth but has a kind of a miss occasionally. And has no power when in first gear. Any one can advise me on this please
 
by the way the MI16 engine is brilliant, but a gti-6 engine would better to go for as it has more power out of the box and is more reliable and more fuel efficient it does weigh more then the MI16 but it is a much better engine, and also it isn't prone to oil surge like the older 16v 2.0 pug engines

i've read once or twice that it occurs to the mi16, not sure if its just the 205 conversions, any one else heard or know anything about this?
 
not heard about any oil surge problems, my friend did this conversion, the only problem he had was the damn wiring. this is surely the worst part as Peugeot seem to have duplicate wires for everything.
 
any one know the widest tyre i can get onto a 1.9 gti wheel, i think they were originally 185's, but when i bought the car they 195's.. i'm just wondering about 205's, or am i being abit ambisious
 
think that's it 195's. the part to watch out for is at the back with the inside of the tyres rubbing the rear wheel arches. Depends on how bad the bearings in the torsion bar are warn. I had 195's on the back of my 1.9 and they were rubbing the insides as the bearings were warn. replaced the barings and then lowered the torsion bar. even with new bearings you couldnt even get a hand between the wheel and the arch - but well worth it! Handling had been superb before now it was just unbelievable,
 
the gti6 engine has a baffled sup on it, and has a better head design,

if you already have an mi16 205 then just a head swap and a gti6 sump would do it.
Head is a direct replacement
 
the MI16 only suffers from surges if u go round a bend really fast for to long, the MI16 engine is muh cheaper than the GTI6 lump, im about to take delivery of a 306 S16 with the 6 speed box from a GTI6, also coming with it is a 306 convertable, im stripping the S16 and putting everything into the convertable so it will be a 306 S16 convertable (ready for the summer), i dnt think theres much between the 1.6 and 1.9, in a straight line they stay side by side until about 60mph then the 1.9 slowly pulls away as it has slightly abit more torque.
if ure friend is thinkin of a MI16 or GTI6 conversion then i would definatly fit 1.9gti brakes all round, the best thing bout these conversions is that you can leave the original gear box in as the GTI6 andMI16 engines fit .
 
Really?
I would have thought the the s16 or the mi16 engine would be more expensive because they are few and far between compared to a gti6 Personally I would still go for a gti6 cause it's more modern, easily available and more reliable

205 gti 1.9 rear beam is a must

but front brakes there are more options
306 gti6
306 s16
206 gti180
307 2.0i / 2.0hdi 137

These are all direct fit onto the front of the 205 brand new the 307 brakes are the cheapest they are the same as the gti180 brakes as well however if you can find some the gti6 brakes in a scrapper then they are awesome value for money
 
i always thought the GTI6 was more money as its more modern, i have never looked into it,
as jarrus464 said, 1.9gti rear beam is a must if u are going to put a bigger and more powerful engine in
 
Something I would mention while I remember is that mi16's and gti6's can have the capacities increased quite a lot by using some parts out of other pug engines,

Can't remember who did it but a guy made a 2.4l mi16 engine, it was bored out to 88 mm and had an xud11 crank with a stroke of 94.5mm!?!!
(off the 406 2.1 dt xud11 engine)

Which makes it an oversqaure engine so it isn't going to be as revvy as it was in standard from

theres a video on you tube of it, it's in a 205 as well :)

hey guys, i have a 1.6 205 that i installed a 1.9 engine,but still not enough power for me so im installing a turbo in a couple of days, any advice before i go on with the project ? parts,methods,... ?
 
Hi and welcome to the forum, we might have to start you on a new thread,

anyways, turbonetics did a turbo conversion for this engine and the result was about 170 ish hp so the engine is up for the job but you will need other parts,
an aftermarket ecu will be required for best results, also how much power were you planning on running and what other mods are you thinking of doing to "contain" the extra power?
 
dear jarrus, thx for the reply, the parts i got: a turbo from a nissan 200SX, BOV, fuel regulator, and a big intercooler, and im searching for some forged pistons, im hoping to run the turbo at 0.8-1 bar and hoping to get around 200hp. what other parts would be needed for this process, i really appriciate ur help
 
no problem, if your engine is in good condition then you may not need forged pistons just a decompression plate,
look up a company called DP engineering, they are based in holland but can ship any where and they specialise in turbo conversions for Pug's and Citroen's, you'd be supprised at how much a decompressed engine can take, and like i said before you will need an aftermarket ecu but most importantly you will require an uprated MAP sensor, because the one on your car is designed to measure negative pressure but you are going to be putting positive pressure (more than atmospheric pressure) though it and it just won't be able to read and thus your engine will run very lean, (big problem) also bigger injectors, that's my advise but it is also worth while sending them an e-mail ask there thoughts as well as they are the experts at this,
and by the way, what turbo have you got? I know you said it was from a 200sx but I mean who is it made by and what model is it? I might be able to help a bit further if you can provide me with that
 
its a Garrett ar.48 , and i was planing on making an extra injector cuz it costs way less and i was told that it would perform the same what do u say ? about my engine its not in pefrect condition it needs some refebishing, i had in mind to change all gaskets, bearing, and maybe the pistons i dont know if this engine can take that much pressure even with a decompression plate i fear that something will brake and i will have to dissassemble the engine again, and i was reading in the site of the company u gave me that the decompression plate costs arround 300$ and i can get the pistons for about the same price maybe a little more here, which one would you advice ?
 
the turbo technics system uses an extra injector so you may want to look how they did it all those years ago, if you can get the pistons for about the same price as the decompression plate then go for the pistons, but something to bare in mind that if your engine has done a lot of miles then the bores in the block are going to be worn, the new pistons will fit but the bores will be slightly elliptical rather than round so there will be excessive gap between the bore and the piston and you will get something called piston slap which makes your engine sound like a bag of spanners (not good), you should get the block rebored before fitting the new pistons (you will need to order pistons that are 0.5mm bigger than the standard bore and have the block bored 0.5mm bigger), it sounds like a lot to do but this will produce the best results and it will be like having a new engine so you will have to run it in, always do this when having new pistons (brand new) in any engine so they fit properly.
 
yes, thank u the pistons i found are 0.5mm bigger and im considering of boring the block, but i want to ask u more about the decompression plate like how much boost can i get with it for the 1.9 8v engine without braking something ? and the pistons i told u about are not new but in very good condition and i would surely get new rings ,would that make a problem ? Turbo is a big world and im afraid i cant go all the way in cz its too expensive so im trying to install a turbo with a small budget but hope to get all the power for my money that's why im asking a lot of questions and i really do appriciate ur help, the project begins in 1 week, and it should take not more than 2 or 3 weeks and then we'll see the result and in the mean time any tips or more info u can give i would really take them into consideration thank you
 
there are plenty of companies that do map sensors, i'd try and find out what the turbo technics conversion uses, thats the best for what you are doing, with the decompression plate 200 hp should be safe, i have seen tu 1.6 8v running more than that on a decompression and that engine isn't as strong as the xu range,
as for the pistons they should be fine, and i'd still use them if you can get them for a good price and bore the block,

i looked up your turbo and 1 bar should give you the required power and torque you want

i also found this, that should help you with what you are doing

hope this helps

ok can u tell me where i can fine the specifications for the turbo i got? and another thing, people told me that 2 head gaskets can be joined together to make a decomperssion plate would that work or the decompression plate is better ?
 
you've got a garrett t25, so look that up in google, they are fairly common turbos, (but not to be confused with the newer gt25)

and yes you can but you will have no idea what compression you will end up with, and using 1 thicker head gasket is better than using 2 normal head gaskets, the decompression plate that they sell is specified to reduce the compression down to a certain point which they give you and from that you can then work out if it's safe (by the way it is) i would personally bite the bullet and buy there decompression plate, but if you do plan on using the lower compression forged pistons then you can use a head gasket that is standard thickness and made of a better material, copper is supposed to be good because it easily flexes and is more resilient to excess pressure
 
ok thanks jarrus, im sorry i keep bothering u with all these silly questions its just that im new at turboing a car and i need all the help i can get, so ill let the mecanic see which would be the best idea and what compression will i end up with, thanks again if i have any more questions u'll be sure to hear from me :p if not ill let u know how the car turned out :)
 
one more thing: the MAP sensor i cant find any company to ship it to my country and here we dont have many tuning companies that would work on an old car what should i do?
 
i know they are simple but as a told u there arent many tuning companies here and especially for and old car like the 205 i guess ill have to search more, what would happen if i ddnt change the MAP sensor ?
