From what I have seen with the cefiro, they have a tad more engine space than the GTR in width so you should have no issues. If you have 2-3cm clearance between the turbo and the strut tower...they will come out.

Easily done.

Undo the engine mount on the turbo side and just jack it up.

You'll gain loads more room provided you have enough room on the plenum side... i havent seen a cefiro engine bay but it could easily be done in my HR31 engine bay should i decide to change turbos later on.

Its not the "most" room. But begin with the rear turbo ;)

Should be able to do it with the engine in.

Two weekends ago some mates and i changed out the turbos on my 32 GTR to GT-SS models with the engine in. It is very tedious and cramped but very possible. It took us 24hrs all up with a hoist, but that also included changing out:

Turbos

dumps

Front Pipes

Welding up Flanges to new catco metal cat

cat

cam gears

timing belt

water pump

Bosch 044 fuel pump

high flowed and port matched manifolds

adjusting oil cooler lines and remote filter kit

I don't know about the Cefi, but i have done several with engine in ( 32, 33 and 34 GTR'S) . It should take an experienced person about 4 hours . It's much easier and much quicker when the engine is on the floor though.

haha i have about 10cm's between the turbo's and the strut tower in the silvia :P was quite a shock when we sat the engine in there hehe

yes its possible to change turbos with the engine in the car.. its a bitch but it can be done.. and it saves pulling the engine out (in my case.. engine comes out gearbox comes out with it.. stupid s13 gearbox tunnel)

Its easy to do with the manifolds on. Just undo all the lines, pull off the inlet snouts and feed them both out the back under the car. Front turbo needs to be loosend to get the rear one out but save the chance of braking a stud and having to buy an exhaust gasket. Was the same in the my rb36 r32gtst as was the 32gtr. People talk it up but its easy. Can be done in 5 hours off and on.

just took my turbos off ;)....it is tight down there with the oil and water lines underneath. took the front pipe off and should have taken the dumps off too but thats pretty hard when the car is only on stands. ended up taking the manifolds out (had HKS steel gaskets)...out of topic...should i get aftermarket manifolds as the stock ones are out now...or should i get them extruded n honed??

just help last time i tryed to take the turbos out, i could'nt get to the bottom manifold bolts, can someone please tell me how to do this..

u have to take the oil and water lines that go into the turbo off first..(you will lose coolant and lil oil) and then take the top nuts off that bolts to manifold/turbo..should have enuff room to move the turbo/s so that you can reach the manifold nuts, then should be 100 percent easier to take out turbos then, once manifolds out. thats how i did it...dont know if anyone did it the same

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
