VVT swap from a 1.6 with PS and AC
 
Phoebe is still going strong (so this isn't now) but at some point her heart will fail so she needs a strong surviving heart.

I'm looking at a BP4W block and a BP6D VVT head following Emilio's suggestions in his thread for engine builds.
I intend to build up while she last spending what i can when i can so I can swap out as quickly as possible.
As this is a daily driver power steering and air conditioning are still present. Given my location you would think at least ac could go but when you're in traffic in the sun and you aren't used to the heat its glorious. Power steering may be optional at this point of swap but that is no where near now.

What I haven't seen much mention of, is how PS and AC are handled in engine swap.
I know most builds are track cars but what about us normal folk?
Is it not mentioned because it literally swaps over?

Use all NA8 parts. The AC compressor might foul the FSB if it's a big tubular unit.

Is there a particular reason for the NA8 parts?
I only ask because I will then be sourcing from three separate engines.

Because the NA8 is a NA with a 1.8L engine.

Why not VVT block?

The NB2 engines (01-05) use a wider thrust bearing. ACL only makes a thrust bearing for the 94-00 BP's so find an alternate for that one.

Being in the UK sourcing the fun stuff is harder than the US so by not going VVT block I make the job easier.

all 1.8L blocks are externally the same as far as mounting all the accessories.

i run a 94 block with a vvt head on my NB2 and all the accessories and sensors bolted on just fine.

It should be noted that the quoted part i used earlier has been removed from the Engine Ideas thread by Emilio but the clarification of only a thrust bearing being different in the VVT block is a worthwhile one. It means I can get everything as is and grab an OEM thrust bearing for fun times.

Are you starting with a 99 1.6? or the early NA 1.6?

NA 1.6 have V belt drives on the accessories, BUT i would imagine the 99+ 1.6 would have the same components as the 1.8s. Simple swap either way, it should be obvious once you have everything in your hands.

There's a UK breaker in the FS section with cheap VVT motors.. I'd guess they'd be $500 each for you. Just go buy one of those.

Being in UK makes sourcing a VVT engine easier than anywhere. In fact, I bought a 30k mile one last week, for literally half of what I would have here.

But was it £600 or like i find on eBay every few weeks £250?
I think we need a talk :)

Thats not the bracket I've found online even including ridiculous delivery charges so would not be that happy paying that.

At the moment I'm kind of look for a transplant motor for emergency only. Once the MOT is done i will know if its emergency or not so can begin playing.
