xr6twin

Hey Guys, Its finally finished! All the pipe work has been completed and now its soon to be heading to the tuning shop to see what numbers we can get out of her! Iv been for a small drive with it running low boost and adjusting the air fuel ratio wit an air fuel meter and it seems to crack like a whip!! Cant Wait to see what it does with some computer adjustments and 10psi up its arse!! Ill post up the dyno sheet as soon as the tune has been done!

There is a curved plate in the center of the smaller pipe that will direct both flow paths into the larger outlet pipe, that is the only way I could direct the pipe work in the direction I wanted it.

Hey Guys, Here are some pics of my ba xr6 twin turbo set up, I really like the look of revenge's header pipes, (I 110% respect how hard they are to make, and you've done an awsome job on em they look sick!) but a high mount twin turbo setup looks awsome! this is the only way I could think of getting the pipework to fit under my bonnet. and this car is street legal!

Hey guys, Dont wanna take any credit away from this thread, but here is the link to my video. Iv got a thread of my own, with pics and info on my twin turbo setup. http://www.youtube.com/watch?v=siyhYY1qW3k Enjoy!!! cheers farnz, we know we're not talkin bullsh*t! lol

Hey guys, Here are some more pics of the build to keep you all interested!!!! From some of the pictures you can see the new alloy radiator overflow tank iv made to sit in next to the brake booster, this gives a lot more room to run the 3" intake pipe to the second turbo. Iv also relocated the battery to the passenger side of the engine bay where the old air box sat, and piped the shaker back into the new air box to give some of that cool air we all love!! Any one with questions, please ask, I love tellin people about my project. Enjoy.

cheers thanks for all the support

not sure of what its going to put out, just have to wait and see when its on the dyno, im gunna keep the n/a motor running stock compression but put 10psi up its ass n see what numbers it gets. I would love to see 450bhp but I dont think ill have the coin to achieve that lol

currently in the process of relocating the battery and making a new alloy radiator overflow bottle and relocating it closer to the firewall

Hey Guys, Got some new pics and a short video of the first crank over with the twins bolted on (hopefully I can post a video on here) The pics and video were taken during the exhaust manufacturing stage so there is no induction pipe work on it yet. Stay posted and ill have more pics of the induction work as it happens.

Hey guys, Still in the process of the build. Keen as ever! Had a few minor setbacks in the wallet department but Im happy to announce that iv started buying more parts and will have the ute back in the shed again this weekend!! Just been working on the twin 2.5" exhaust then the turbos can go back on to start work on the induction piping. Stay posted as I will be adding more pics as the build starts to take shape again. Cheers. P.S Thanks for all the positive feedback and comments you have all been sending, makes the project more exciting to get finished!

Hey Guys, Just wondering if any one knows what size the injectors in the standard BF MK1 XR6T are? I got a set off a mate for free when he put larger ones in his xrt, but im not sure what size they are. Cheers.

Hey guys, I had idle problems with my ba xr6, worked out it was a blown intake manifold gasket on number 1 cylinder letting in a whisper of air when throttle was shut, causing the ecu to adjust fuel air ratios on every cylinder then deciding to lean them all out. Result was rough idle then would speed up then drop off to nealy stall then speed up again. The issue is not noticeable when under accelleration unless your running a turbo, then you will notice a loss of boost pressure and more lag in spool. To check for leaks get some soapy water in a little bottle and tip it around where the intake manifold bolts to the engine while the car is running. If there are any leaks you will see bubbles start to form. Hope this helps

Cheers for the support. Yes t04e turbos Yeh turbo's do sit pretty close to the overflow bottle, but im gunna put a catch can instead, and run the hoses into a different spot so they dont interfere with the waste gate actuators. Got a heap of fibreglass wrap to go round the manifold and dump pipes try and keep the heat down a bit, thinking about putting aluminium barriers up to protect the heater hoses and hydraulic clutch line. Gunna control boost with a dual stage electronic boost controller. Waste gate springs are both set to 8psi but with lowereded compression and possibly forged pistons and rods will hope to run upward of 14psi. My understanding of the boost controlling is once manifold pressure reaches the boost I want both gates should waste equally to regulate to desired boost, even if one turbo is making 8psi and the other is making 6psi, once maifold pressure reaches 14psi they should both regulate equally. Currently got an old sigma on lpg as my daily driver while im working on the ute, hoping to get a good bit of work done in the next few weeks, ill update progress as it comes. Any info people want to know just ask, im more than happy to share my success and failures. (more failure than success so far)

Hey Guys, Only new to the Turbo forum but already like what I see. Iv seen a topic on here started by a guy talking about twin turbo on an XR6, and every ones comments and opinions on the subject. Well im currently in the process of doing that exact mod the thread was discussing. Here are some (not all, I have hundreds) pictures of my project so far.

Cheers mate, its good to finally talk with someone who supports my idea. I got two t04e turbos, internally gated at 8psi, but im going to the trouble of pulling the engine out and doin forged pistons and h-beam rods. My engine is a N/A ba MK1 so im leaving the compression higher than the standard turbo, say around 9.1:1, possibly less. It started with 9.8:1 but with concave pistons should drop the comp down to a good ratio to run about 12psi+. I got heaps of pics on camera ill upload some when I next get the chance.

The reason why you cant use your pacemakers is because they are mild steel. the heat and pressure generated beteen the engine and the turbo would melt the headers faster than you can say holy sh*t. Iv just finished makin up a set of header pipes for a twin turbo conversion on my xr6 and its all been made out of 5mm thick steam pipe. The reason they say your stock headers will work better is because they are cast iron, and can handle the heat and pressure. The only other way to go is to get a set of headers made out of stainless and are ceramic coated. But if your making a kit that will last the best option is the steam pipe.

Hey Guys only just stumbled across this post. Im actually in the process of putting twin turbo on my BA xr6 ute. Been working on the conversion for the last 2 months. There is plenty of argument on whether a single or twin turbo setup is better, but at the end of the day it all comes down to trial and error. If no one has done twin turbo on a 4L inline 6 then how can we argue that a single turbo is better or worse. Im making the conversion simply for the fact that its not often you see an xr with an engine bay with twin turbo.
