Nice can’t wait to see it underway

Love the father/son friendly competition.

I'm all about the Audi engine swaps! I've test fit a 1.8t into a 987 Cayman chassis and it fits very well. I am currently running a 4.2 V8 in my Boxster. My dream build is a RS6 powered 911 C4 or turbo chassis. I'm very much looking forward to this 914 project!

[@budgetoutlaws9978]

Ive contemplated buying a blown motor 986 and just throwing in a 1.8t as it's essentially the same trans as I have now. If I could find a way to reprogram the PCM to work with the 1.8t file I would be golden ;)

[@budgetoutlaws9978]

What did you do ECU wise for the 4.2? That is such a great swap!

[@finchers_garage]

@@budgetoutlaws9978 I'm using a stock ME7.1.1 computer. I deleted the immobilizer and fixed it so that it doesn't need a vehicle speed signal input (otherwise it limits my RPM from 7200 to 5405). I've done the Megasquirt swaps before but never got them to run and idle like they did on stock computers. These 1.8t's are ME7.5 computers. The whole ME7.X computer is pretty well documented on nefariousmotorsports.com. I can help out too if you decide to go that route.

[@budgetoutlaws9978]

Great offer! I may take you up on that! I have a tuner for the ME7.5 and am on Maestro for this engine swap.

[@finchers_garage]

Having a tuner for your specific computer is great, especially with a turbocharged engine! There isn't too much support like that for the 4.2L's (unlike the 2.7t's) but I hope to demystify the complexity of these swaps. VW/Audi made some great engines in the late 90's/early 2000's.

There are more reasons why this swap makes sense too. An Audi engine bolts to a Porsche Boxster transaxle and several Audi transaxles. You don't need $3k worth of custom clutch, flywheel, bellhousing adaptor. A more powerful, better shifting 914. Less money, less weight. In the 1970's a Chevy 350 was right. Transaxle choices are better now, and 4 cyl engines have huge hp and tork now. The Audi 1.8t 5 valve per cyl head was designed in part by Yamaha. If you are watching a video like this you already know more about great cars than most people. I could go on ...

[@NachoBides]

Lol there is no yamaha involved with 1.8t. It is an audi design

[@jerrybrian4743]

You are right as far as Yamaha working with Audi. Yamaha was making a 5 valve head in the 80's and so was a pioneer. My bad. Nacho is right !

[@NachoBides]

@@jerrybrian4743 Yamaha was one of the first to mass produce engines with 5v heads. But it should be mentioned that audi was also experimenting in the 80s. They had a 2.2 5cylinder 25valve turbo engine which produced 650hp. Of course it was only used in racing, but this was actually the testing base for the mass produced 5v engines (1.8 20v turbo and n/a, 2.8 / 3.2 30V V6 and 4.2-liter 40V V8).

[@NachoBides]

@@jerrybrian4743 Yamaha is actually associated with toyota 5v engines. Their heads are said to be designed in coordination with yamaha (4age 20v etc..)

Looking forward to see how you might have solved some of the same issues that i ran into with my 1.8t swap. It's nice to hear your thoughts on this as opposed to just reading it on the forums. I went down the same route as you but had a couple more swaps a 2.2 Porsche (too expensive to rebuild), Chevy 350 (too heavy and doesn't fit with the character of the car),G-60 with the Lysholm charger 8 valve then 16 valve G-60(great setup but hard to make a longitude 16V), before getting my friends 1.8t to put in my Teener. The only dissapointing aspect of the 1.8t swap compared to by g-60 versions is the lag from my gt28rs, it doesn't really come alive until 3700rpm, where the g-60 was instant but died out in the top end. I will put a light flywheel into mine eventually and see how that changes the drivability of the turbo lag.

[@budgetoutlaws9978]

When I had a GT28RS in the a4 I had instant throttle response over 3k, instant boost. It felt like a v8 over 3k. What are you doing for boost control? How aggressive is your timing map? I would venture to say you could bring that response down considerably. I had a 16lb flywheel in the Audi and the 914. I think I would have preferred a lighter one but I suspect that would negatively effect boost response (Load and heat build boost).

[@pstreetgarage7304]

The V8 would have been good enough for me but nice choice. Need to watch the next vid 👍

[@PedalBox]

Sounds great, have one question we're still avoiding looking at as long as possible on our midengine 1.8 build. How are you routing the gear selectors?

[@budgetoutlaws9978]

Next video on the Audi swap will go into transmission, clutch, and shifting in detail. But to answer your question it's a cable shift with Boxster cables and a boxster shifter and custom linkage on the trans side.

[@djradicalray]

I’m thinking about doing the Audi swap. Not sure yet on 1.8t, 2.7, or even doing 4.2. I know for sure that I want it to be automatic with tiptronic! Not sure if I get a fwd 2.8 transmission or an older boxster transmission? Any thoughts we would be appreciated and do you have any blueprints or details on the engine cradle? Thank you, Ray

[@budgetoutlaws9978]

Both the boxster and 2.8/1.8 auto trans are roughly the same. I do know that they are NOT that strong. I for sure wouldnt do 2.7t, they can make too much torque. The 4.2 would be OK but you'll have to be concerned with torque. A 1.8t with a medium/large turbo would be a really good idea with an auto. If you put a high stall on it and firmed up the shift points then you could have great power with no lag between shifts (Since your not letting out). The auto/tip trans however is not a fast shifting one though so just be aware of that. The other benefit is you can readily get an engine/trans combo that was designed to work together and they can be had for CHEAP. No blueprint on the cradle, I will be making a whole video on the mounts in a couple weeks. I designed mine pretty simple, once you have an idea of what you need it doesnt take much to mock it up and weld some mounts in.
