Cam, I think it's possible to put a steel wheeled RX7 turbine in a machined RB25 turbo housing, might cost the same as a rebuild but provide a bit more power and reliability.

Im quite sure this is what I have, boosts up to 16psi easily, one day ill get around to the dyno.

I always use ATS in O'Connor

Cheap n Freindly service.

Rebuilt my VLT T3 with T4 internals as well as Hi Flowing......$1200

It has produced about 280rwHP @ 9psi on 9.0:1 comp RB30......I'm hoping it will be good enough to produce 400rwHp on 7.8:1 Bottom end I now have !....?

Anyways - on inspecting the compressor wheel on my old turbo vs my new one, I found that the new one has dual vanes while the old one has single? Any ideas? I'll post up comparative pics tonight.

Righto - Pic of the old vs new compressor wheels attached.. Any ideas?

Hmm - fitting the turbo is turning into more than just a re-bolt on. Have found some problems as a direct result of bad workmanship by *** performance (in wangara - you work it out) who fitted the dump - missing bolts and flange holes not lining up by a mile. You wouldn't think the fabrication of a flange would be so hard...

Pic attached of the poor workmanship of the dump. Absolutely pathetic and I think people should know so they can be aware of the quality of work to expect out of some places. You could argue that it'll work - which it will - but you'd expect this sort of crappy workmanship out of a backyard mob - not from somewhere who suposedly specialises in "performance" work.

i know with the mitsi turbos the TD04 is single blade and the TD05 has the twn blade thingo like yours cam, not saying its mitsi, but maybe some sort of upgrade, which might explain rev's times??

Might explain my times if this turbo was actually off my car. My turbo has twin blades tho' for the record.

I personally think people underestimate the effectiveness of a lightened flywheel..

*thinks back to the nissan micra super turbo on GT2 and the difference it made when he lightened the fly*

granted, that was a puter sim, but a lightened fly would make a hell of a difference.

    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
