Hi can you help me to know different between audi tt mk1 engine the 185 hp and 225 hp

Mister Bally

40 less horsepower, different cylinder head, exhaust manifold, turbo size is smaller. Exhaust system is different. Only one exhaust pipe & cutout at the rear of the car.

Quattro not standard, only front wheel drive with the 185 hp engine. Only a 5 speed manual available, not a six-speed. Automatic transmission is available though.

If you mean how do you tell by looking at a TT? The 180 has a single tail pipe. The tranny is 5 speed manual or automatic. The 6 cylinder 3.2 TT also had an automatic tranny but has 2 tail pipes.

If you mean internals, the 225 has a different turbo and beefier piston-related hardware. If you do a search on this forum, there was an excellent write-up on the internals differences.

Also, for more information about the Mk 1 model differences, read this FAQ.Fourtitude.com - Audi TT FAQ

My engine 225 hp broke so i got the 185 hp i need ti know which part from my old engine to be fix on the 185 hp to came 225 hp

Mister Bally

Let's us know how you do that without the correct cylinde.... everything I mentioned in the above post. You kinda got your tit in a wringer. Buy a used 225 hp engine and sell the 185 you bought.

In the US you could get the 180 engine and Quattro in the 2000 and 2001 coupe. All Mk 1 180 roadsters were only FWD. Read the FAQ I referenced earlier for details.

I agree with you that buying a 180 engine to convert to a 225 is a poor decision. Better off just tuning the 180 with a chip, DD, etc.

the 225 also has a second intercooler correct?

And agree, don't convert the 180 engine, just chip it.

Mister Bally

Yes, two intercoolers, but they can both be used with a 185 HP engine. Not sure how the smaller turbo and if the manifolds will mate to the intercooler piping though.

Buy the correct engine is my suggestion. Then again, what do I know?

Between you and your son, way more than all the rest on the forum...

I'm with Mister Bally. Bad idea to down grade. There are other issues with the drive train. Besides you will de-value your car. When you get the car on the rack you will see many differences.
