Engine overhaul, maybe more
Good evening,
Just got myself a 85' Coupe Quattro non-turbo, it's at 205k on the clock, so I'd like to give the engine a good going over. Now I've been researching how much power you can get from these motors (still unsure on the answer). But I've been looking into big valves, cams, manifolds and intake, and maybe forging for adding a turbo later! I'm abit unsure what I'm wanting at the moment! So my questions are; If I go and stay Naturally aspirated, what is the highest, but safest HP achievable, and can someone list the modifications and where to go... If I fully forge and turbo to 350-400HP, who is the best person/company to go to for this, and what sort of final cost is it? I'm used to turboing Honda engines so no idea on Audi costs. |

I’d be very interested to hear about this as usually a swap to a x flow 20v 7a is the recommended route. I’ve got a KV and a KK sitting around unused

But at the moment I'm just gauging interest, If it's under 5k to turbo, I'd be happy. If not be nice challenge to see how much I can get from a naturally aspirated engine. |

To get anywhere near that target you'll surely have to go down a turbo route? If you are sticking with contemporary engines from the Audi stable the 2.2 20vt from an S2/ urS4/S6 is the most trodden path, although there are a myriad of 1.8 20vt projects too, usually sourced from A4 etc.
To put into perspective a normally aspirated 5cyl 2.2 KV well fettled with a port/polish, big valves, aggressive cam etc is good for 170/180, hence why the 2.3 20v 7A engine is also a common transplant, as you get that "out of the box"...

This is the plan if possible, take my 2.2 10v and add a turbo, I'm sure it's been done, really don't want to 20V for some reason I don't know, maybe I'm after a challenge lol However if N/A be good fun to aim for 170/180HP |

i hope you can stay as enthusiastic throughout the project, there are others around here better placed to advise on the best starting point / path to take, as you have probably rightly identified already though, turbo-ing your existing lump may be the most difficult way forward. Even if it is possible, a better "bang for buck" may be achieved from a more mainstream choice...!
Having said that, I wish you all the best with it Looking forward to the build thread

Hi massier1993, You have had a number of reply's from very knowledgeable members on this forum and over all they are trying to push you away from the 10v engine upgrade weather N/A or Turbo, I have a B2 Audi coupe Gt front wheel drive, it came with a 10v KV engine and sounded good, I did a year hill climbing with it and wanted more power, my move was to the 2.3 7A 20v, the actual conversion is very easy, £500 and I had an engine and every thing to make it run, gearbox, flywheel and clutch was a problem but in the end was an easy fix, as for living with the engine, starting, running and mpg are much better and more power and with a cone air filter, well you know when I'm coming past you, I also own a 1984 10v WR Ur quattro, my ownership of the car is in its 26th year and with my knowledge of the 10v turbo charged engine I would also be pushing you away from that type of conversion for your 10v engine, I also own an 1991 Audi S2 3b 20v 220bhp out the box with a home fries chip fitted, so 270 / 280 bhp and it is a rocket ship for a car from the early 90's, as for you quest for 350bhp well thats a big leap from you KV at 136bhp, don't think we are all sticks in the mud, we are trying to save you money, time and effort, find your self a well priced 20v turbo engine, gearbox, diff and all the bits you need to make it run in standard format (220-230) and see how you get on, you will need to upgrade wheels, tires, brakes and all suspension, hope this reply hasn't put you off but you know the saying "been there done that" as many others on this forum have done before.
