Boostwerks.com turbo XJ build...

The cfd is some pretty cool stuff, but I guess all you really need to know is no sharp turns, quickly changing diameters, etc. Seems like you're already doing a good job with the honda manifolds so I can't wait to see these. With meth injection you can surely have some fun. Dunno if Id run much more than 6-7psig without an intercooler unless you want to retard timing.

Yeah using the flow software on a log manifold would be pretty useless. :P

I wouldn't reccomend boosting at ALL without retarding the timing btw. Too much timing with boost is the easiest way to get detonation.
 
Hey Bryson, I was just talking to my buddy about this setup, and he's in the same situation I am - we don't want to ditch our headers ( I know I don't want to remove my hotjet coated banks header if I don't have to).

Anyways, he suggested something pretty interesting (I'll try to explain it the best way I can). The 2000 headers are 3 into 1 opposed to 6-1 like the older headers, so how about a twin turbo set-up off the downpipe? This way we could use 2 smaller turbos and keep our headers.

There is no room to fit 2 turbos under the intake manifold. 1 will be difficult.

Agreed.

It's one thing to fit the turbos, but getting the piping routed is a whole different story.

Sell it. :yelclap:
 
Bryson, I mocked up my up pipe and most of my down pipe today. 2.5" DP coming back down is a bitch. You got my vouche if you get a 3" in there with the way the axle and driveshaft compress. What a pain in the ass..

What side is it exiting on? Tuck it up against the frame rail/floor as far as you can.

So you feel good about the 3" DP fitting a stock height truck?
I honestly don't know about the stock height vehicle. When I built the first manifold setup, I was able to squeeze a 3" by the UCAM on my stock height rig BUT never did drive the rig to make sure it would clear under all circumstances. I may end up having to indent the DP like the factory peice, but I honestly won't know until I get that far. Having the turbo much higher than the previous manifold will definetly help. My rig is now lifted 4" though, so I may not be able to truely judge the feasibility of a 3" DP on a non lifted rig.
 
So are you going to have stipulations on your kit? Like it needs to have a certain lift or axle?
Dude. Read the post right above yours.

Stock height and 2.25 is a lil tricky, needs to hug the oilpan real close to clear the drive shaft under flex. Hell, I'm running 2.5" lift and the exhaust guy didn't quite get it right.
