Conversion from 1.8T to 2.0T
Has anyone done the conversion from 1.8T to 2.0T. I understand with the 2.0T with a upgrade EMC Chip the horsepower is rated at 310HP. Is this correct?

theres a 2.0T?
No, those numbers sound totally wrong. You could stroke your 1.8T a little probably and jump up the figures though.
You speak of a 2.0T as if it were some standard engine. I don't think that is the case.

Lol, No (long and technical)
The 1.8 uses an underbored standard audi block (taller VW block). The 2.0 was the 4cyl audi block for decades. Since the block dimensions and attachments are virtually identical, some folks (back in 98) reassembled 2.0 blocks with 1.8 parts. Whoopee.
A total non-event. The limiting factor with the 1.8 is not the size of the motor, that is *at best* an incremental additive effect. Turbo motors can have multiplicative power increases with boost and efficiency changes.
Get a proper sized ball-bearing turbo and a FM intercooler and you will blow the doors off any 2.0 with some cobbled together design.

isn't the 2.0 conversion just a different crank...
quoted from dahlback:
"Max. power 550 hp (405 kW)
Changes New E-proms in ECU, optimization of flow to intercooler, new turbo, custom built exhaust manifold, intake manifold, wastegate, intercooler, injectors, fuel pump, fuel pressure regulator, camshafts, crankshaft with increased stroke (2.0 L), piston rods, pistons, oil cooler, clutch, flywheel, air filter, modification of air filter housing and charge air hoses and pipes, extra engine mounts, modification of crank case breather, porting of cylinder head, 2 x race cats, stainless steel exhaust (turbo-back).
Note The software maintains full functionality in terms of diagnostics, engine protection and fault code memory.
Only for cars with quattro, 6-speed transmission from Audi RS2 is recommended."
I guess this car got the treatment...

Yes, his name is Cameron on his previous A4. I think he had upwards of 320 back then...
Along with this, he had:
> > new driveshaft
> > new axle extension
> > new pedalbox
> > new dual master brake setup
> > new six-plate racing clutch assembly
> > new transmission
> > new engine displacement
> > new rods, pistons, cams, and crank
> > new turbo
> > new hood, front bumper, rear bumper, side skirts
> > new seats and six point harnesses
> > new roll cage system with chassis stiffening
> > new custom valved KoniSport shocks with new springs
> > new instrumentation, STACK8130
> > new wheels, two 18" 8.5x18 wheelsets
> > new headlamps (Xenon)
> > new carbon fiber surfaces to replace rear seat
> > new Alcon B-Type brake calipers on 13" Coleman rotors
> > and a couple other things.

Stroke 1.8T, right? more (long)
In the Honda world, some people stroke the 1.8 Liter VTEC motors with a different crank to get 2 liters. This requires custom rods and corresponding pistons as Xr4tic noted...
This goes along with the old adage about displacement. There are some All motor VTEC hondas I've "heard" about with B20 blocks from the CRV and VTEC heads making 230+ HP at the wheels, with considerable (for an all motor Honda) TQ. Like 160+ FT-lbs which is a lot when you rev high and don't have a lot of weight (2200 lbs Civic shell).
In the Honda drag racing scene, Lisa Kubo stroked her B18 to 2 liters and with lots of boost in a Civic ran a 9.X 1/4 mile...
The problem with stroking the HOndas is the Rod/Stroke ratio which is alreadh bad in a B18 VTEC Honda since it's already a stroked B16 VTEC motor... Going to 2 liters makes it worse.
What is the rod/stroke ratio for the Audi? It's like the opposite (undersquare?) of Honda motor and designed for TQ, right? Soooo, stroking it may yield a better rod/stroke ratio? The "ideal" ratio is supposed to be ~1.75. The Honda B16 has this ratio and can rev very high reliaby. One mod is to take the B20 CRV motor (2 liters) and put the crank from the B17 in there to DESTROKE the motor, but get an almost ideal rod/stroke ratio...
Anyway, how does this relate to Audi engine specs? How would it affect the engines reliability, revability, rod/stroke ratio?
Doesn't APR's Stage IV kit include a 2 liter stroker kit?
Thanks,
FB

Sorry but lisa bored and stroked her motor to a 2.1 and has plans to do it up to 2.2 or 2.3
and no the apr kit only replaces the rods and pistons. I know someone that was planning on doing a 2.0 conversion but have not heard back from him in a while.

Where are you getting that info from? That car was lucky if it had 225hp. Sounds like you have been talking to Todd at Vortrag to long. The only motor work that was ever done was buy the dealer after the turbo(stock turbo) wastgate broke.
