Default Odd question - Outside dimensions of VR6 engine at largest/longest points? Thinking about stuffing

it into a very small engine bay, so room for it and auxilaries is important. You can see the space available by looking at the battery.

Default that a longitudinal setup... so you may have some additional difficulties with a vr6

why not a 1.8T long block with turbo?

Default 1.8T will just be as challenging as it would be a custom mount to some tranny

VR6 would be simpler to get up and running imo

But I'd probably look at other manufacturers too - maybe a Mazda 2.0 V6

Default Yeah, Mazda had the 1.8 V6 with 130hp, but It doesn't look that much smaller than the VR6.

Given the packaging issues with intercooler and heat, the 1.8t ain't cutting it. At that point we'd just get some warmed over Alfa engine that we know fits, and max out the tuning. Want the torque of the VR6 and the sound - which if you know Alfas, is half the reason to get the car;-)

Not too worried about fitting it a longitudinal setting, since we've done this with other cars and have a killer machinist. Just need to make sure it can physically fit - for the most part anyway - that's what welders are for. The lower portion between the front suspension is pretty narrow and we can't fudge there.

Default my 1.8T makes more tq at the wheels than a VR6 at the crank

come on April, do the right thing. I wouldn't know about the sound of a VR6 because I never fall behind them :&gt;P

Default Agree on the Alfa sound! The GTV6 is music to my ears!

I found a web with a lot of info on many engines - autozine.com

But no VR6. They do have a Veyron engine dimensions, so maybe you can cut the dimensions in half and divide the long side by 3/4

I wonder if you can rough it's size based on the A3 engine compartment. It's gotta be a tight fit in there.

Default Yeah, but it lacks a nice linear delivery (remember, it's going through 195 series tires,

which are already a massive size upgrade over the original 155 tires) which is going to make that old solid axle design very unhappy - and probably break it to boot. The stock engine is incredibly tiny (1300 to 1600cc), and there is no room for intercoolers, radiators, a/c condenser, power steering coolers, oil coolers, etc.

It weighs well under 1000kg. The whole car is insanely tiny by modern standards.

Italian cars aren't all about going fast. It's about *how* you go - maybe quickly, maybe not;-) I love the sound of the VR6, the creamy power delivery, and the progressive power feed is very Italian, so it's not out of character with the car.

Here is the donor car at our friend's place:

Eventually we hope to make it look a bit like this:

Default Ballparking it, it's very close. Accessories will be the challenge. As it gets closer,

we'll buy a hopelessly rusty hulk and use that as a test jig (making sure we have our tetanus shots of course).

Do you think the 12V VR6 will fit better? It looks like a much smaller top. Good power from it.

Default Hence the request for some dimensions before I go hacking up some other poor car

and buying a VR6 engine;-)
