I’ve added this to my list of engines we need to talk about :) stay tuned! We look forward to bringing you more content!

Thank you so so much, that means a lot and I look forward to continuing to bring you videos like this. If your engine is in running condition we will build it for £7k and supply a 3 year 40k mile warranty with it. 7 day drive in drive out turnaround package.

​@InfinitPerformance refreshing to see a price given for the work and not the normal "contact us for a price" so they can try and push the hard sell. You can keep this price in mind when actually looking to buy an RS3, great content and like many other people keep saying your knowledge seems 2nd to non. Also to offer a 40k millage warranty is unheard of, fair play and keep up the great content

@@nickarmstrong4458 I 100% agree, was surprised I was given a price to be honest haha. These guys are clearly very open an with their knowledge, these guys would be the top pick for getting a built engine! As and when the opportunity arises, of course.

​@@InfinitPerformanceWOW. I wish I could ship my car across the sea for you guys to work on. So many sketchy shops in the US

@@FU-Utubetrue!!

Glad you enjoy it! I look forward to bringing you some more great content.

Well from my experience 850 American whp is the equivalent of 850 crank European hp. I limit the stock pistons to 850 European crank hp.

The stock head studs are monsters on this engine. After rods, we would be looking at upgrading the pistons for high torque applications. The stock piston is a cracking design but the metal is not that strong and can shatter with bad tuning on heavily boosted applications.

@@InfinitPerformance Thanks really appreciate the reply do you use JE because you feel they are the best option or availability sorry for all the questions just have always loved the 5 cylinder

@@marshgatelaneposse we have the best Experience with JE’s or Mahle pistons by IE. Some others don’t suit the aluminium block too well!

@@InfinitPerformance cool now you just answered the other thing I did not know I take it it’s a coating not a a liner is that the main restriction in your view or valve train design really take my hat of to your ability with this motor

We run our engines in hard, on the Dyno :)

@@InfinitPerformance The correct way to do it. I've been telling people for years the 1,000 mile break-in the dealership tells them is BS. The only thing you really need to worry about is seating the new rings to the cylinder wall hone. And that happens pretty quickly.

We are using the factory timing tools supplied by Audi :)

Thanks 👍

We have our own brand rods, drop us an email if you'd like a set!

Good question! I do not deem it necessary to balance the crankshaft itself based on this engines use case. So for example this is our Stage 1 engine build w/ 3 year 40k mile warranty. No turbo setup on 99 octane fuel with or without power adders is making power past 7500rpm up till the 850hp marker. The crankshaft comes with 4 different clearance sizes for the tolerance in the crank bearings from the factory, the rod bearings come with 1 which means these cranks leave on extremely tight tolerances from the factory. We do balance the rods & pistons within 0.3g of the lightest. If we were doing a build for an application that was going to be making power past 7500rpm and consistently be in the 8krpm range, along with a balanced rotating assembly there would be other changes I would be making to the engine. We actually have a build underway which I will showcase next month (G35-1050). This client is looking to do the occasional drag day so would like to have E85 capability, I will note though that even the G35-1050 is not making power past 7500rpm on a ported head on 99 + power adders... Once you go past the G35-1050 size of turbo you are introducing huge amounts of lag and a car that is simply a drag car at that point and will not be enjoyable at all to use on the road, we are very limited in the UK as we do not have easy access to E85. We like to build cars that are daily drivable and enjoyable hence rarely ever going above the G35-1050 or Xona 8264S size of turbocharger. If I had any doubt in my mind about the above, our engine build programme for this platform would be hugely unsuccessful. We have built over 50 engines in the last 3 years with more than 20 running for over 2 years now. Only Audi have the balls to warrant the engine for 3 years and 40k miles. From the knowledge gained over the last 5 years of working on this platform, when hardware and software are working in perfect harmony I am more than confident to offer the same level of warranty.

Thank you. If we can help with anything, drop me a message at anytime 😊

Glad you liked it!

Thank you!

367hp models are CZGB engine code!

Thank you! 🙏🏽

@@InfinitPerformance gracias

😎

Yikes! That wouldn't be good :)

Well, we forgot to put the crank sensor in!
