Yep you should be able to send it over the end of the clock. The 2ltr lump goes much better in a 340!

The advantage of a blower is you do not get the kick you do with a turbo. The blower is always forcing air in and icreases presure with rpm.
The turbo option would be the easy way as all the 1.7 bits will bolt on. The 2ltr lump is not as bad as ppl make out.

Just keep the boost low.

Still don't think you should just 'bolt on' a Turbo without checking what spec internals should be.

If you run at a low boost to compensate for this, there's not much point having the hassle of fitting it.

You don't want to spend all the effort and money fitting a Turbo, for the engine to basically pack in 500miles down the road. I'd look at Mark480 thread, and search for the Turbo 2ltr and check his specs.

Wont give anymore
 

My 2.0 stops at 115mph and has little more to give! this is going uphill slightly and with only me and full tank of fuel. This is using high octane petrol too. Perhaps a little tuning is in need!!! The engine runs very clean though and I do like the mid range torque but I'd prefer it to give a little more all round as I'm sure the engine could hack it. Dont know where I'll draw the line though as the host of internal changes for turbos or superchargers sounds like a fun if expensive experiment. Had some fun though the other day coming off a roundabout onto my local stretch of dual carriageway (duel carriageway if you ask me) People in BMW's really do over rate their cars sometimes.

Aha! My girlfriends little brother wouldn't shut up about his new 316 so I took him out in my (now sold) rusty old bucket 2.0 litre ES. After hitting 120mph in half the time it takes him to get to 90 he squeeked "You can stop accelerating now..."

As for topping at 115 don't know what could cause that, just check everything. You could also try playing with the cat. I hollowed out my first one and it just lost masses of torque. On my latest 480 (Celebration 023/480) I just bored a hole through the ceramic centre, about 30 mm or so. Kept all the torque and a bit more top end power!

Not the exhaust
 

I hate exhausts there bloody expensive

By hollowing the cat out, you just reduce back pressure way too much, as there is too much of an expansive space. Only a straight through pipe will make the difference (just put the cat back on for MOT time).

115mph is too slow. As a 'cheap' mod, i'd try NOS first and see what you think. Then a Turbo after. For ultimate fun, slip in a T4.

Steve

i think youll find the 2 litre has been turboed , and can be done for little money , and , as long as the boost is kept low , and your engine parameters in check itll be fine .

NOS is overated , and will certainly almost cost as much as the turbo conversion .

the T4 engine didnt fit for some obscure reason i cant remember

@Steve B: Hollowing out the pipe did make some improvement but there were also downfalls, as stated. By just boring out the centre of the ceramics inside the cat you get the best of both worlds. It also kept my car well within the limitations for emissions come MOT time.

@davebslater: Do you still do the fibre glass arches for the 480?

Exhaust
 

So I need to work on the exhaust as a start then! Am I right in thinking the turbo manifold will bolt straight on? People keep saying it's better but I'm unclear as too whether it's a straight swap.

As for the turbo thing!?! Such conflicting views. I'm gonna go with the yes version from dave blaster but then I'm stuck as to find out where to go from there! I know theres the fella in Germany with a 2.0 turbo'd 480 so perhaps I'll find some literature on the subject! I'm interested in how daveblaster would go about it though!
