which turbo did the S1 use?

[HORCH]

can somebody tell me which turbo the Audi S1 used and which modern turbo has the same spec? preferably still a kkk though,

thanks for any help, rob

k27

[HORCH]

so just a plain and simple k27? are there any numbers that I need to know or anything?

[terrybullwon]

Search imsa on this forum, you can see the part numbers for the turbo it used iirc it's something daft like £4000 worth of kit

K27 is a series designation. They actually used different units in different rallies.

You most probably like to read through James Bufkin's website at http://www.bufkinengineering.com/rally%20car.htm

[HORCH]

wow, thats a good read, he's got some special bits there

so what will I look for? because they were specially made for audi sport and I dont think I'll find any of those on ebay I've searched but I cant find anything that says "you need to get this" and I dont have 4k spare for one haha

will I have to use a combination of two turbo's? or is there just one certain k27 turbo available?

[terrybullwon]

Is there any reason why you want a "s1" turbo ?

Things have moved along way from these dinosaur KKK's

[HORCH]

well I love the audi s1, so to be able to say to myself my turbo's practically the same as an s1's would be spiffing

wether its old technology I dont mind, I know theres loads of new turbos that are probably way better but ? I dont know, what would you recommend?

I haven't read thru that website (too busy at work for that atm -> maybe this afternoon ) but I'd have assumed they continually tweaked these things to eek out more power? If you are after a replica I guess it's a case of what version do you want to replicate - or as James said, there's alot newer technology out there now.

My hybrid K26/7 for example, comes in earlier and more progressive with 450hp capabilities compared to the 380-400 of the K26/7 I replaced.

[HORCH]

hmmm? I'd like it to get me 500hp easy if possible?

but yours sounds good ross, where would I get one? and what part numbers do I look for?

as you can tell I'm not clued up on turbos but I'm learning

[caterpillar]

billet BW(kkk) are the newer and better turbos... the old kkk27 did have the 8 hotside, but the development are gone some futher i think...

[caterpillar]

and they did rev the 2,1 liter too 9200+rpm= THATS music in my ears!!!

You want easy (I read cheap) 500hp and you thought the way is to use an ultra rare rally car turbo from the 80's? Brilliant!

I could have said,
