vq40de first gen fronti swap
well im goin to start off by saying this isnt goin to be a quick build... my fronty is my only vehicle and i still have to tear down the vq40 and do a minor rebuild before i pull the ka24de out to start the swap... i will document the vq40 build here... once the build is complete and i find a cheap beater i will begin the swap... let me just say that the vq40 is a very difficult to find performance parts for... ive been researching and researching interchangeability of parts from the vq35de, vq35hr and vq40... so much misinformation on the web its ridiculous.. there is no aftermarket performance piston or rod company that make pistons or rods yet, exception of a custom set made by cp that's way outta my price range so i will be keeping the stock rods and pistons and just re ringing the 135k vq40.. i will be using vq35hr stock head studs, since they hold more pressure then arp studs for vq35de.. i will also be using vq35hr head gaskets..once the heads are off i will be able to figure out if i need to have the block coolant ports grinded down for the hr head gaskets, i will be using king rod and main bearings once they are released sometime this month..
here are a couple pics i took of the vq40 when i picked it up and the start of the tear down..
