2.3 l engine is little too big because of gas consumtion

(I'm a student afterall)
I heard that some alfa diff could fit to 300 models. is that true?
is that 2.3 l engine agile or lazy (I need agile engine with good response) what to do about gearbox? can some other fit?
Ok. I just put the 2.3 as an example for power freaks.

2 litre turbo engines are also available. Volvo 700-series had B200ET, B200FT and kinda rare B204FT/GT which were equipped with 16V head. Though not all countries did get the 2 litre engines. I guess most countries had only 2.3l? We had 2 litre too because of taxing reasons at 80's.
200-series had 2 litre B19ET turbo engine. B19ET is better than B200-series engines because it has much stronger con rods. (As strong as the 90+ B230-series, though the ones in B200 series are not so weak either, they will hold approx. ~250hp in normal street use in turbo engine)
It is also possible to turbo the existing 2 litre B200 engine in 300-series as the internals are same what comes to power handling as in B200-series stock turbo engines. Only thing is that some B200-models have too high compression ratio like ~10:1 so that should be lowered. Of course it is possible to turbocharge with high comp.ratios also but then you need very good programmable engine managment system.
My GLT has B200E (2 litre injection engine in 360 GLT) with an exhaust manifold and a turbo charger from 200/700-series. Oil return for turbo has been drilled in to block etc... About pistons I am not sure. They could be the ones from turbo engine or then they could be stock because comp.ratio in stock is 9:1 so it would be possible to turbocharge with stock pistons too as I don't have so much boost. ECU is stock Le-Jetronic with extra-ecu which comes on under boost and it controls the fifth injector. I didn't built it my self and I guess that it has been built in somewhere late 80's/early 90's so complete turbo engines from bigger Volvos weren't available so cheap as they do nowadays. Today I would go for complete turbo engine from a bigger Volvo if I would start building 360 turbo because it would be a lot less work I guess. Of course if all parts are available you can also turbo the B200 engines in 300-series.
There's a list of all engines with specs used in Volvos throughout and explanations for different engine codes. There might be some inaccuraties considering the 300-series etc.. but pretty much it is reliable list.

Nature of these Volvo engines differs much because there were so many different comp.ratios used in different year models and different camshafts again depending on yearmodel etc... so there's no general answer I'm afraid. If you wan't info about Volvo turbo engines this is your site:
www.turbobricks.com there's a LOT of info considering the turboing existing engines etc... few articles about that and a very big forum with loads of info. Not much about 300-series though because it is an American site and they didn't get the 300-series but as the engines are same family in 360 as in bigger Volvos the info there is good in that area.
Edit: Oh yeah and all OHC-redblock engines look the same outside. (Except of course the ones with 16V head

but the block is the same looking) Differencies are internal so outer dimensions are same in 2 lite, 2.1 litre and 2.3 litre models.
Then there are also older OHV-redblocks but those were used in Volvo Amazons,140-series,P1800s,PVs,Duetts and such classic models. Just though to mention that you dont mix up these in OHC engines what I was talking about above.
This is pretty much what 8V OHC redblock used in 200/300/700 and 900 series looks like:

Of course there are some minor differencies in details such as different looking rocker covers, oil caps, manifolds etc.. but that's the basic structure.
And then of course it is also possible to tune these engines as naturally aspirated too. But I think there's more work then though because there are no naturally aspirated 8V redblocks available which would have over 140hp stock. B23E in 240 had 140hp. Foggy who writes here though has gotten out ~140hp from his B200 engine and it is naturally aspirated so that is a possible way too.
Well.. Long message so there might be some mistakes or then I could have written something kinda unclear but feel free to ask more if something didn't cleared up and I'll try to answer If I can.
