Haha, carbs We live in 21st century, guys
Carbs - it's a simple and complicete solution in the same time. Simple - because there isn't so many bolts In the same time - what else u can do with car like this, apart from sound and a little power increase, because it doesn't consumes fuel anymore, it guzzles. Example with corrado & carbs = 170 bhp isn't cool - i know ppl with mk2 golf, 2.0 DOHC engine, vems and some minor modifications, and 175 bhp. I'm afraid, that car with vems can be used dayly, unlike car with some primitive carbs. Well, i also know one another example - B2 A90q, ppl installed in this car 7A engine, installing on it pure k-jetronic from KV, only nozzles were different. Fuel consumption was 10l/100 km on road, 20l in city Price for torque As owner said - he was able to drive in 4th gear on 1k rpm without downshifting

going from a 136bhp 16V motor to 170bhp with the addition of carbs and a head job (Head prob gives 10-15bhp increase) I think is pretty decent add some cams in the mix and you'll be knocking on the door of 180bhp!!!

Anything that increases engine performance is going to knock fuel economy, Bike carbs are a lot more fuel efficent then a set of twin 40's webbers etc!

And what u will do, if u want 200, and not 180? In that case u will trow out your "very cool" carbs to install EFI & turbo

If I wanted 200 bhp I'd throw away the old motor and fit a 1.8T

Default TB's

As stated already the inlet manifold length is there for a reason. Take the 20V 7A, the inlet was 'tuned' to help midrange torque. Fitting bike carbs or TB's right next to the head might be great for top end power but on a road car thats not going to be as useful as a good spread of torque that can be achieved with tuned inlet and EFi. Unless it is going to be used as a track car don't bother, there are better tried and tested solutions . See July's Audi Driver on fitting a larger MAF to the 7A for instance. 190bhp and 180lb/ft torque from aspirated 2.3 engine.

Think most of you are missing the point, it's all well and good saying well I'd just put a bigger better engine in than carbs or i would have gone for 2k worth of throttle bodies and a mapped ECU if you're gonna argue that why not just buy a faster car.

Is this what modifing old cars is about?

Surely the point is to make an improvement over the stock equipment?
Carbs are not going to achieve it in my opinion, as the stock injection system say on a KV engine isnt restrictive at the power levels the head is capable of supporting in stock trim.

Im all for modding engines, cars etc but id not sacrifice power economy and reliability for uniqueness, however appealing the idea.

Having said that though, each to his own, and if Gaz or indeed anyone did do a conversion to carbs id not knock such an effort id always applaud it.

Well... Why 2k? 1k would be much real

Originally I was wanting to fit a 5 cylinder 20valve turbo engine to my car.. but when i saw the 2.5 Nasp lump for sale i went for that instead.

I do scratch my head and wonder 'WHY?' sometimes, esp when looking at 20vcqdriver's turbo install, i think i'll have fun trying to reach 200bhp from my 2.5L.

How exactly i'm going to achieve that i don't know, but i'm hoping with a fast road cam i should see about 190bhp, Any ideas tho how i might take it from there to 200brake??
