4.2 swap into 2001 A4

[Sales@RAI]

What n/a 4.2 will make more power than a ecu tuned 2.7t

Why does the 4.2 need to be N/A?

it doesn't, I was just quoting you from post #221. Let me refresh your memory

To have BT horsepower N/A stock?

BT 1.8T not 2.7.

BT 1.8T not 2.7.

correct. Champion, while a 2.7T is cool, a 4.2 in a B5 is just awesome. You can't beat V8 torque

a chipped 2.7t has more tq than the 4.2 n/a

Have you driven both cars?

There's a completely different sensation between 2.7T torque and a N/A V8 torque. Even if the V8 has less torque, it still has a more neck snapping feel the second the pedal is floored.

no, but I know how to read a dyno chart

[JumboBlack1.8]

Man, I would LOVE to do this if my motor were to blow (*knock on wood*)

[Sales@RAI]

no, but I know how to read a dyno chart

Thats fine, one day when you drive both you'll get what I'm saying. My car makes ~450awhp and ~400awtq but I'd easily take a V8 with less cause it'll beat me every time

[JumboBlack1.8]

^^Agreed

[Rb26dett s13]

^X2.. less headaches too.

I think I need one with ITB's... Imagine that sound! screw a 5857 on a tubular mani!

Possible true with peak torque, however it's the area (power) under the curve that really makes a difference.

Hey russian so was a lot of re-wiring needed in order to get the OEM Ecu to work with the car?
A total of how much would something like this run me if i were to do this swap? using oem A8/A6 ecu?
I would also use Drive by cable engine

Sorry I've been MIA for a while, been busy as hell with work school and additions to the V8 (will be posting up soon)... but I've had quite a few questions about the cost of the build... so here is a quick estimate that i've put together in my head for you:

So lets see in reality...
Engine: $3400 (2001 4.2L drive by wire 52,000 miles, with all accessories wiring harness and ECU)
Timing belt kit: (~$400 just to have it done)
RS4 clutch: $1400
Milltek Downpipes: $1400
034 stiff OE race mounts: $140
S4 Transmission stabilizer bar: ~$200 i think
Electric Race fans: $200

Total: $7140 so actually almost 8K if you include all the small little things

and to tag onto the 2.7 convo... they can make a shit ton of power... but i don't want to be the one that has to pull the motor to service those turbos... thats my opinion in a nutshell...

Thanks I appreciate it, Seriously considering it and finding an Engine off a 97..but was a whole lot of custom work needed to have the ECU work with the car? hope that makes sense?
Also what adavantage was the RS4 clutch over any other after market clutch?
Just need to set up my budget.

Holy shit dude,what a effin cost.and on another note, td chicago bears...lol

a good big turbo build would not be too much cheaper in my opinion... and you Americans with your silly passtimes you call sports...


as far as custom work... I think i've described most of it in the thread... its not like swapping a BMW engine into an Audi, some things line up and just work, others need tinkering... I needed to wire power to the ECU and Fuel pump for example in the wiring...nothing extreme, just takes lots of research/studying to figure out how to do it and keep it integrated in teh wiring harness because not everythign works the way its supposed to...

People easily spend twice that on 4 cylinders. Ask me how I know

People easily spend twice that on 4 cylinders. Ask me how I know

Truth!
30 series turbo 1300+
Clutch 1000+
Intercooler 1000+
Manifold 500-1300 (depending what mani)
coolant/oil/etc lines 500
built motor 3000+

SHit that list goes on and on and on... not to mention $$$ just for random parts and up keeping.
