Stumps

I remember seeing in Street Machine a few years back a red XF that had a blow thru setup on the crossflow with a monster sized Pulsar turbo that made over 400rwkw's.

*crickets* not a good sign...

Not going to brand bash here just want honest opinions on Pulsar turbo's. Im looking at getting one for my XB and they are very cheap but seem to have good reviews, especially from xr6t guys. Are the worth looking at for something that will rarely see a track and do limited daily driving?

I have a complete VCT engine to use including the correct ECU. I'm just wondering wether its worth playing with or should I use the 94da top end I all so have sitting in the XG in my back yard. Looking for the best bang for my buck type of thing. Both engines are currently running so they pretty much just need the bottom ends freshened up.

that would be awesome if you can. I think something close to thom's 180rwkw's beast would be more than enough for the XB. I'm pretty sure the XG engine I have has a 91DA cam in it, but I havent had it apart to check, but I was rebuilt by HM Gem a few years ago so who knows what it could be lol, I can only assume.

from my understanding the difference between the 94ab and the 94dt (ef xr6 head) was the valve size, pretty sure they had the same port size, but I could be wrong. I'd assume that fitting the larger 94dt sized valves to the 94ab head would bring it up to the xr6 heads flow rate. Does any one know what the exact specs of the EA Falcon's cam is?

Is the AU tickford head any good flow wise. I checked out my XG motor, it has a 94AB head which seems to be one of the better non tickford e series heads.

Apologies for raising an old thread, but it's not covered here. Is the AU XR6 VCT topend worth playing with as far as the head goes? Would the VCT itself work with the EA cam, I'd assume if it did, the VCT when it kicks in would make the profile a bit more aggressive again compared to using the cam in non VCT cars. Sorry for the dumb questions there seems to be limited info on hotting up an NA VCT engine outside of locking the cam and using the non VCT cams.

Is the XR6 VCT topend worth playing with as far as the head goes? or should I be looking for a different head like the EF XR6? I have the correct EEC to suit the VCT with a 5 speed. I was thinking of running a Barra ECU for extra tunability would it be worth going to an FG coil pack arrangement? I have what I assume is the stock XG engine as well with everything needed to run that so swapping parts is doable for sure.

http://www.ozfalcon.com.au/index.php?/topic/1233-thoms-40l-thread/& Been reading this thread, very interesting read indeed. Seems all I need is an EF XR6 head to build thoms combo, got all the rest of the parts, pretty sure the XG cam is the 91DA cam spoken about in the thread. Would come pretty close to getting the XB into that magical 13 seconds bracket I'm chasing.

*crickets*

Pretty much what the title says, can the AU 4litre bore out to 60 thou, which would pretty much give it dead on 250 cubic inches. Is it worth the effort going for 60 thou, I know crossflows and a lot of other sixes have no issues with a 60 thou overbore and it gives about 6 extra cubes on a 6, but is overboring the block really worth the effort? Also does anybody have any recommendations for piston brands these days. Normally I would of just picked up some ACL's but seeing as they dont do that stuff anymore, what's the next best thing?

Total valid points, the more I drive the car about, the idea of just putting sniper injection on the log motor as is and just cruise around seems like a good idea. I probably should just start by getting a reco'd strommy and electric dizzy and fit it and see how it goes as is. It's spent the last couple of weeks as a daily and it's been very pleasant to drive around, gotta get rid of a few rattles and squeeks but other than that and being a little cranky when cold it's just such a nice car to drive about. Gotta get aircon for it now summers around the corner...a retro under dash unit would be right a home I think.
