The h22 block+gb weighs 16kg more than an equivalent b16 block+gb (source: honda-tech).

A turbo with manifold and associated gear will weigh almost 16kg, especially with a cast iron manifold. What's worse is that all of this weight is placed further in front of the front axles in comparison to a H swap.

Now you go and boost your b18 and be outhandled by a boat anchor.

hey guys, big prob with car well basicly it doesnt idle, it just drops and stalls, pretty sure thats the iac valve has died, however the main problem being is that its lost all power, if u floor it, it just accelerates rele rele slowly and makes a loud air noise, sort of like the fuel was cut off any idea which valve was doing this, i reset the ecu made no diff, ill do an error check on the ecu tomorrow see what comes out, just seeing what you guys think

Thanks

hey fellaz
had a problem for the first time with my da saturday.

Went to start it, just kept cranking over but wouldnt fire up, checked all the ignition leads n dizzy, tried again same thing, this time i went over made sure most wiring connections were clipped in properly, tried again, fired up for a split second then died, moved a few things round cranked it no fire, left it for a minute or two whilst praying it wasnt the fuel pump, cranked it again... fired up n stayed on.

later that day happened again at the servo, but this time after the same routine was followed after like 2 crank attempts, nothing, turn the key, nothing. okay that had me totally stumped, battery and starter are fine, they didnt tick like when you try too much and drain the battery, reds were on strong too, called my mechanic mate down, he checked it out, checked a relay for the alarm, tried to start it, fired up first go, asked him what he did and he swears he didnt touch anything, no problem since knock on wood...
any ideas? anybody had similar problems...

Happened to me once, just misfiring. If it happens again, check for oil or water on/near your spark plugs, also check the dizzy with a multimetre, maybe the ignition coil is on its way out, normally if its going it will struggle to start and die randomly while running

cheers

Is it after you start it cold drive it for a short period and stop and then it won't start again? I'm 99% certain its the main fuel relay, its the most common problem in Da's. They were badly soldered so you can either replace it, or pull it out and just resolder the connections, Google it and you should be able to find a picture showing where it is and what the badly soldered connections look like.

+1 main relay. 99% definate
google a diy fix it yourself with a bit of flux and solder.
or i think you can get a new relay from honda for like $130ish.
the way you can tell is that you won't hear the fuel pump prime and that yellow light on your dash will stay on. fix it before it strands you somewhere. it will get worse with summer coming on too.
