unmarkedf6 Member 50 Member For: 11y 6m 26d Gender: Female Location: The locker room, toweling down Posted 10/02/16 10:38 AM Share Posted 10/02/16 10:38 AM Hey guys thought I'd share my bf xr6 turbo manual ute. Was previously making 378kw till the fuzz defected me. Was running 80lb injectors, in tank herrod 265lph fuel pump, aps intercooler, x force full exhaust and high flowed( 64mm gtx wheel )standard turbo. And a heavy duty clutch that barely held up with the hell I put it through! so I lost interest in just repairing it. Now I've pulled the engine out and am currently rebuilding it! I went with spool rods, Ross forged Pistons, crank girdle, main studs atomic timing chain tensioner and chain and aftermarket oil pump so far. I'm still sussing a few things out with the top end besides valve springs obviously driveline will be another issue but I'll deal with that when I get there hahaha goal with the engine is to have a powerful, yet still drive able daily driver, (ideally 480+kW) being a manual limits my choice of turbo and drivability. I'll figure that out later here's some pics let me know what you think! also included parts of my timing guides which fell apart and (I think) caused a rattle on cold start up! 1 Link to comment Share on other sites More sharing options...

Go arp head studs, atomic washers, single layer head gasket and some e85. Or if your super serious go 14mm studs but that's more money. Nice twin plate clutch and you will be ready to go. 1 Link to comment Share on other sites More sharing options...

How much power do people push through these setups? I figured I wouldn't go any harder than about 550-600kw? Link to comment Share on other sites More sharing options...

A lot of my mates with xr6 turbos have done the gtx35 thing so that seems like the norm to me now. Not gonna be going to the drags just want a fun street car what do you guys reckon? Or is there a low mount option with a ~68mm compressor wheel or something? update on the engine, currently getting the block bored and decked and getting a second check on crank and tunnel measurements while its there. Been told it should be all done, mid next week. Can't wait! 1 Link to comment Share on other sites More sharing options...

Should I be going smaller than 1.01 for the rear housing size? update. All machining and clearances checked and double check, now I've just got a bill for all the machining ? I'm still undecided on cams. I've bought an fg engine to use the head and a couple bits and pieces. Link to comment Share on other sites More sharing options...

And we're starting to see positive boost pressure at 2,200 rpm with my GTX4202R. Given that we haven't done anything (Yet) to assist spool, I think that they are capable of being very drivable and diverse turbo. I have opted for an Atomic stage III cam, as we're going spend a lot of time playing with cam timing and retaining the VCT's just has so many benifits. Primarily, I really want the car to have good manners and economy. But, we are expecting to see a lot more torque in both the low and mid range and a faster spool and higher overall hp. 1 Link to comment Share on other sites More sharing options...
