Re: twin TD04 project
You can see he has mounts coming off the intake manifold bolts holding it up from a bracket.

Re: twin TD04 project
Forgive me but would it be practical to remove the airbox and replace it with a cone filter and a turbo?
Also, the windscreen wash fluid reservoir could be scrapped in favour of something smaller crammed in somwhere else. Without any insight in the matter, I would opt for a setup which did not direct air around and about. I would think that a shorter and straighter flow would be better? I've just entered a research programme into intercooling. Wher would you place a MAP?

Re: twin TD04 project
The more apt solution would be to mount the turbo where a stock ej22T turbo goes, but up it to a GT3071R with the 81mm housing and run a FMIC.
I'm just not a fan of all that heat right near sensitive electronics, so I'm making a twin low-mount setup work for me. |

A MAP sensor is typically built into a standalone ECU, such as a Hydra or megasquirt. You just run a vac line from a port on the intake manifold to it.

Re: twin TD04 project
No, it's not easy, but compact it is .
The steering rack is no problem. Also, the wiring loomes at the top are well protected - both by the heat shield on the turbo and further insulating wrapping. It's all been there for thirteen years now. See photos. /T |

Re: twin TD04 project
That really is such a good setup for leaving the creature comforts undisturbed. Remind us all what kind of turbo that is, tapani? And how do you feel about it not being intercooled? Also, where do you have the MAF?

Re: twin TD04 project
It is a small T4/T3 hybrid. Boost only 5 PSI. I guess it produces around 280 hp, but the low/mid range feels like it should have from the factory.
You can't really tell is blown by driving it. The turbo spools at 1500 rpm - not very easy with the automatic :-). But for what it is it performes very well, I think. It would be nice to measure the compressor discharge temperature and see if an IC would be of benefit. The MAF is in the original position. The bypass valve is practically the only give a way at a quick glance. See photo. /T |

In my case the waste gate is an integral part of the turbine casting, but it works the same way as so called external ones. A pneumatic actuator opens a valve and let's part of the exhaust flow pass the turbine inlet. The turbine and compressor side details must be separately selected for the application at hand to get the target results. /T |

Re: twin TD04 project
I recall in another thread you were hitting fuel cut on 5psi. What's your ecm solution, LAN?

Re: twin TD04 project
With the stock fuel system I hit fuel cut at 5000 rpm and 5 PSI.
I now run Deatchwerks 370cc injectors, stage 2 chip from Mike and the Nissan MAF. Works pretty well. At WOT (and 5PSI) AFR is 13ish until app 4500-5000 rpm and then app 12.2-12.4 up to shift point @ 6800 rpm. /T |

Re: twin TD04 project
Wow nice, you're running it out to 6800? Do you have cams to let it breath that high?
I don't recall ever seeing a build thread of your car. |

Re: twin TD04 project
No, but that's where the full throttle shift points are, yes? Maybe my memory is off, I don't do that very often :-).
The turbo was installed in 2000 by the previous owner. You can follow the JDM drive train + TBDs if you look for the "traction project" in the tranny section. http://www.subaru-svx.net/forum/show...project&page=2 And some basic info under "Toy" here in turbo..... http://www.subaru-svx.net/forum/show...&highlight=toy Some of the head gasket stuff was here: http://www.subaru-svx.net/forum/showthread.php?t=61822 The engine runs much better now (after the overhaul) than before - and feels stronger by butt dyno :-) /T |

Re: twin TD04 project
Ah, I see. Thanks, I recall you chiming in in the past, and reading a bit about your car, just not a whole dedicated thread.
Thanks for the reading material |
