205 GTI cylinder porting .

[bobblegut]

I'm thinking of getting a 205 GTI and maybe tuning it up a little , not crazy stuff just improving whats there already . I would need the cylinder head done mildly but don't have a clue as to who could do a good job . I can remember a company back in the day advertising a head with a whole jar of aluminium they had taken out , which i thought was a bit mickey mouse , its not about making everything huge . Has anyone had any experinence first hand ? Do CNC heads do them ?

Relatively hard to get much extra out of the 205 engines as they were pretty well developed from Peugeot.

Dave Baker from Puma Racing Engines used to do these and put some useful stuff on his website. The website has now gone (not sure whether Dave retired?)

Found some of his writings here......
205gti.3xforum.ro/post/106/1/Totul_despre_motorul_lui_205_GTI/

......which may help.

Thanks . Good real world information .

Yeah Dave knew his stuff pity it looks like most of his knowledge has being lost if his website is no more

I'd speak to del at skip browns in Tarporly Cheshire to see what they say

I would take what dave wrote with a truckload of salt...

depends on budget, but the best pound for pound power upgrade is more valves.

I've rebuilt an 8v recently that cost comparatively little to build, 1.6 pistons in a 1.9 (11.9-1 compression) newman ph4 cam, kent double valve springs, standard parts otherwise.

throttle bodies and an ecu, 175 bhp ish.

Thanks for the replys , welshpug i would like to keep it original so I'm afraid more valves is out of the question , as would be throttle bodys . Slightly bigger valves and a compression increase sounds the way to go .I'm not after mad power ,just improving . Am i right in thinking Skip Brown did the whatever class A/N rally cars for peugeot ? I remember hearing the name banded around in motorsport circles .

What about peugeot sport , are there any bits which were avalible from them ?

[swampy76]

Skip brown developed the 205gti in the early days.

Very knowledgable bunch if folk what they don't know about Psa cars ain't worth knowing!

They have being in the game for many years

Yes, more is no doubt available from the 1.9GTI engine, but it's hard to get as they did such a good job as standard.

Thanks ^^^^^^^^

Peugeot Talbot Sport did a kit for the 1.6 back in the day.

What Welshpug and VitesseEFI said. It seems to be known that the 1.6 GTi was already tweaked well by Peugeot. One way many do get more power from it IIRC is to use the 2.0 XU10J2 head.

If originality is important I guess you could keep the original head to one side .
