I've not done anything this weekend. I was laying turf..

So, here are some pics of the single throttle conversion. Eventually I'll fit my own plenum, but 1st I want to see what the nissan one is like and do a comparison. Hopefully the existing hard pipe bit will fit onto it. I've has to cut everything down alot and cut off all the unnecessary bits like the wax stat and stuff.

I've also removed all the old butterflys and blanked the holes off. The end plugs are bonded in but the center plug is screwed too. I'd hate for the engine to try and eat it.

Here is what the Q45 throttle used to look like. It's the 80mm version.

Here is mine.

With some luck, the butterfly will be operated by the ECU. The AEM will(I think) be capably of this. But even so, I've left a bit on here for a cable incase I'm wrong.

Here you can see how much I've cut off.

Here is the bit I cut off the plenum to try and keep the overall length somewhere near.

But I'm still 10mm too long. I think I can still get the pipe on. Time will tell.

There is a flange to be welded on. I think I'll 'O' ring the seal between the throttle body and the plenum. That way, I can make a thin flange and if it distorted a little, it will still seal.

Here is the blanked off old throttle bodies..

I'll be fitting the engine this weekend.

About time....

So more fun and frolics to come.

I still need to sort a few bits out, but a fair bit can be done in the car. Water pipes and such.

And hopefully, the weekend after, I can fire her up(or burn her down depending on what happens)

Anyway, enough waffling. If you're bored of this thread, go and vote on one of Mycroft many and pointless polls. I'm sure he'd love that..
