Hi guys,

Just invested in a Pug 205 GTi with a couple of mates. It's gonna be a track car so we've stripped it out, but we need some ideas on engine tuning and generally increasing track performance.

I figure someone on here must have owned one at some point or raced one in a ministox class. So what parts can you recommend for little cost / maximum performance gain?

And before anyone says it, we're not buying a 99c resistor....

Cheers guys,

Peugeot

(...I mean McLaren)

Hmm. Get a roll cage - the best 150 quid you will spend on it - from memory (a mate did it to his car) the fuel tank needs to be taken out if you weld it in. And a decent set of sticky rubber, vented grooved discs and decent (EBC greenstuff) brake pads & braided lines. Don't rely on 15-20 year old rubber lines.

A cheap upgrade is to get hold of a BX 1.9 GTI 16valve. It will drop straight in. Keep the 1.6 gearbox as the ratios are shorter. Alot of weight can be saved by changing the side & rear glass for plastic.

After that lower it a bit and a cam, throttle boddies & mappable ign should provide enough to scare you...

Then there is the manifold, exhaust etc etc.

And run it on proper petrol (Optimax)

The best improvement you can make are the roll cage, tyres & brakes. This is a must BEFORE increases in power. Hopefully the brakes & tyres will stop you using the roll cage in the event of yours, or somebody elses mistake. Shouting Marshall aint gonna help!

Oh and b4 you go out put some black tape on the roof. Being put back in the green lane or brown (sand) won't be helpful


Otherwise have fun! Remember anybody can be quick in a straight line the corners are the fun bit.

Dont forget.... less weight... more speed. Rip everything out that aint tied down.... parcel shelf - speakers - carpets etc etc.. Just be carefull when it come to lighting etc and wiring... some grass classes dont require lighting others do.

Engine improvements..... If you planning to run in a 1.6 class and cant upgrade to a 1.9 - then the process is virtually the same.

Exhaust - 205's have a flexible exhaust joint, due to the way the engine is mounted and its a right pain. Basically, chop away the exhaust from that point, and make up some steel wired Mesh tubing to replace the joint with. Relplace the exhaust again, no need for a performance package.

Engine prep is where its all at... I never did it on a 206, but did do a Golf mark2 1.8 GTI. Removing the fuel injection system and replacing it wih carbs, a pair of twin webb 40's sorted it to be damn quick. They were expensice tho - £750... setting up was a pain. Combined that with a fast road cam, you can go alot further, but on an already tired engine? Im thinking cost effective as well as performance...

A cold air induction system is relativly cheap - K+N or similar... Uprate your HT leads and sparkies, to ensure you get a good, consistant spark.

If the engine is a high miler, get the head milled, (this can be done while the cam is being put in, (cost all depends on how many passes the miller needs.) Have a re-enforced head gasket put in... (again relatively cheap). This will sort out any chamber pressure issues. By the time youve done the above, you should be somewhere up around the 160 BHP mark. Not a vast increase in power terms, but the 1.6 engine can handle it.

If you dont want all that hassle, then source a smaller engine. Renault 5 GT turbo engines are a little rare on the scene now, (its exactly the same engine a 205 1.4 XS or a citroen AX 1.4), with a turbo and a bit more wiring. Its lighter than a GTI lump and a bit more fiddly to get set up, but power increase are % higher then the 1.6 lump.

Protect that angine, which ever you choose, with a decent sump guard. You will need a decent set of adjustable shox for the front and. The rear trailing arms will suffice if you want to keep costs down. Just change all the bushes to a decent set of Eurothane bushes. A 1/4 turn on the trailing arms bolts will see the rear end rise and fall up to 1inch either way.

The 205 is a good car to start with. Having been around many in my youth, Ive seen a number set up for rallying and grass tracking, and there a relatively cheap car to make good and competative. Itss all down to how much you want to spend and what class your gonna be racing in.

I totally agree with getting the brakes sorted... no point going quicker if you cant stop it.

Keep us updated on how you get on.

Cheers

Also as its a 1.6 you've got drums on the back. You can fit the rear suspension of a 309 to a 205 which will improve rear track and give you rear discs too.

A mate is ex-peugeot and runs his own garage. His speciality is 205s. 16V conversion is best bang for buck mod plus carbs.

I've owned 3 so far and wouldn't be averse to buying another. Almost bought a Sorrento Green Turbo Technics 1.9 but alas someone beat me to it and I believe is no more

Sorry, couldn't let that one by.

Totally wrong!

The 5 Turbo is an overhead valve Renault only (unless you count Dacia
) unit. Absolutely nothing like the TU Peugeot/Citroen lump!

Didn't want anybody spending money un-necessarily!

It is different as it uses pushrods from the cam

but it was found orginally was a Volvo lump from the 340-360 range.

Get the handling & stopping sorted before the power.

The 1.6 engine was considered by some a better engine than the 1.9. Less trouble and lighter.

Andy - your era now has to the the Senna/Brundle Macca era 93 or 94? with those engines which went bang on the start line...

Thank you Mr.C, I knew there was something else that the Renault unit was fitted to, but it didn't come to me at the time
At the risk of sounding pedantic (
too late) the 360 had the 2-litre OHC Volvo unit!

Being an EX max power reader you will find that the 1.6 is alot more tunable than the 1.9 for some reason. Most of the pugs I used to read about were the 1.6, mainly lightened bottom end, carb conversions, ram air systems and the like.

Best way to do anything for the track is lighten to the max, sort the handling, then think about more power.

Volvo 340 petrol engines were of two sizes, 1.4 and 1.7 only the the 1.4 was Renault and was generally regarded as being better bolted together than the larger lump. Still hated my 1.4 340 though! I'm not sure why it had a non-Volvo unit but suspect it may be a hangover from the days when it started life in Holland as a DAF prototype.

Oh Dear!


It's me again!


Sorry Coop, the 1.7 was a Renault motor too, as fitted to 5, 9, 11, 21 and even Trafic vans, just a larger capacity, slightly more modern unit i.e. OHC with rubber toothed timing belt drive.

I cant remember the engine numbers of the top of my head, and all 3 cars are either dead or in other owners hands.

I owned a 205 1.4, my brother a R5T and a friend at work an Ax GT... I was having valve trouble and reduced compression in 1 chamber caused by running on unleaded. When trying to source replacement valves and regrinding the vlve seats I set about on a mission to get some. I went to peugot and they referrred me to the Citroen garage as my engine number related to a set of Citroen engines purchased when the engine factory was on strike during the mid 88's... The engine from my car was produced by citroen, and it was exactly the same block as the AX of my mate from work. (I know this bit aint in question... however the full explanation helps.) Where I think Ive misslead, is that the engine from a R5T will go directly into the 205 as its no bigger, having read through what I wrote back then, I clearly didnt mean to misslead... hmmm.... sometimes my fingers and brain dont work at the same speed.

decent induction will help no end, left the rear of the bonnet up to help the hot air escape so that the filter doesnt suck in hot air

get a decent manifold, cams, chip, or an Mi16 engine and throw that in

Cheers for the helpful advice guys!

Project is on the back burner for the moment, as I'm concentrating my efforts on a flying Metro for Top Gear. Watch out for it in a few weeks.

When we've finished with the Metro, the Pug is back on and I'll utilise all the useful tips.

Cheers,

McLaren

Yes, actually...

Cheers for the heads up Diff, but I've found that one out already...

Great fun
