hi guys,

i did a search but could not find the answer - my brother has an r32 gtr with blown stock turbo's, been off the road for 4yrs!

i want to help him out & offer to pull the engine out of the car (with his help), he has a large garage & i can get an engine stand...i have pulled enignes out of other cars in the past on my own (i am mechanically minded) i.e. commodore, subaru, gemini, datsun 1600 & fj20turbo etc & that was quite easy.

i have heard different stories about the rb26dett though so i need advice on whether it is difficult or worth the heartache.

options 2 is taking the turbo's off whilst engine is in the car which looks very painful for access & room.

thanks,

My friend done this for the first time on a R33 gtr last week, took him 4 hours off and 5 hours on, only took a bit longer as new manifolds were used and was difficult to get to the nuts that hold turbos to manifolds, and had to remove a compressor cover to get to them easily.

only tools i moded from memory 12mm open end spanner cut down for rear inside turbo flange on rear turbo and

rachet spanners will be good and lots of bandaids or 5 axis small ass hands and most important neighbours who not mind swear words

The ones I had trouble with are the manifold nuts directly behind the turbos under the manifold. Also ratchet ring spanners seem like a good idea in theory, but most times the head is too large to fit where it needs to be.. much like my hands.

Stubby ratchet ringies are your best friends when doing GTR turbos R+I.

Done it over three times now, just need access to top and bottom of the lhs of engine.

Remove front turbo and manifold first then the rear. Just look up the manual for instructions.

Takes about a day depending on lots of things lol.

If the turbos are blown, i would do a compression test before you do anything. Its fairly common when gtr turbos blow to take the motor with them.

do u think the bottom would have let go at the same time?

when u start the car it wont rev past 3000rpm - revs like an old datsun like its choking...no power at all

If the car has been sitting there for 4 years,

i'd pull the motor out for sure, and replace all the heater hoses etc etc around the engine..

tho its not sounding the best, perhaps leakdown, and compression test. and even take the head off to inspect?

I rebuilt my stock turbos with steel internals.

You Don't need to take out the engine to replace the turbos.

Just have to remove all the piping on top till you get to the turbos.

that actually sounds highly likely - that has happened on my previous car & the symptoms are identical

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
