Advice on swapping a f20a for a h22a1

Hi all,

As i stated in my welcome post i am seriously considering swapping my 2.0i engine for a 2.2 vtec to drop into my new lude and need some help with getting a few things straight before hand.

1. Engine. Am i right in going for a h22a1 for a 2.2 vtec? any other reccomendations as to which will be best and most straight forward for a swap?

2. Transmission. Will i need to get a transmission from a 2.2 vtec lude in order to match the engine or will my transmission be alright? Also, apart from the gearbox itself, is there anything else along this part that needs to be changed? Finally, If i bought an engine from an automatic prelude, will i be able to bolt on a manual box easily or should i aim for a engine from a manual tranned car in the first place?

3. Ecu. I gather i will need the vtec ecu from the new engine in order for it to work properly, but what else will need to be done in order for it to communicate correctly with it being in a new shell? Also, What about milage? Lets say i pick up a vtec with 70,000 miles on the clock and my car is on 92,000, should the milage on my car be left alone as it is or matched to the new engine? If not, how should i keep track of the milage on the new block?

Apart from these factors, is there anything obvious i should know about before i take the plunge and go for it?

I appolgise as i am asking an awful lot for a new guy, i just really want to get my car running correctly
