yeah, a mate of mine did his with motor in car, but he swears he'll never do it again.... take that comment how you like.

CHEERS

Thanks. I know it can be done just a right p--ck of a job.

Was quoted $1000-1500 for labour so was going to do it myself. Does any one know how hard it is to take engine out from top as i dont have access to a car hoist only engine crane. Have done this sort of work before but not on a gtr.

dont try it with out a hoist ... you will do your self 2000 dollars worth of mental stress if your not tooled right for the job.... I did it all myself and ended up dragging it to a hoist to finish ....> motor in

I did mine with the engine in - do a search as I posted how to guide some time ago. it is not that difficult, it just takles a little while (I mostly did mine at night after work)

Do you have a copy of the workshop manual? as this makes it easier as well (details the process )

yeah. if there roughly the same size externaly. it should take you about 5 hrs. stubby 13mm spaner is your friend hehe

ive done about 6 in total. kunty job.

What is the best way of diong this? Bolt the turbos to the dumps, then bolt the manifolds in then the turbos to the manifolds?

Its an 8 hour job. Its difficult but not impossible with engine in the car. The hardest part from memory was the rear turbo flange nuts. This is where the 13 mm spanner comes into play. I didnt have any spectacular tools at the time but i dare say a stubby spanner as previously mentioned or perhaps a rachet spanner would work wonders. I did it in my garage with no hoist just on stands. Then again i've removed and replaced the plenum and throttles on my engine about 5 times with the engine in the car now too so maybe i've just built up some extra patience..

Yeah do as you just mentioned in that order, best to take a look at the service manual.

BTW: Dont remove the engine its a big headache. Not worth it just to do the turbos IMO

id reccoment to pull the engine out. Have you even seen the spece you need to work in, i get nightmares just seeing where the turbs are located. But then again, if you dont have the right equipment it can be a big PITA. Even so id still say, pull out the engine and do the job poperly.

So did you do all the turbo stuff, put turbos in the car, then bolt the manibolds to the head then the turbos to the manifolds? did you take the power steering out first.

I attached the dump pipes to the turbos then sat them in the engine bay (as the manual suggests) then bolted on the mannifolds to the head then attach the turbo to the mannifold flange. From memory the power steering can stay there, i may have unbolted the p/s pump and pulled it aside. can't remember just see how you go. If it will make it easier then do it. Honestly though ive done both, removed the engine and removed and replaced the turbos. Engine removal is a big job and will need a hoist + engine crane. On the other hand turbo removal while engine is still in the car is tricky but alot less work. Trust me

did mine not long ago with engine in.....was a s--t of a job....but then putting back on was easier i didnt have to to use the water lines :D (trust turbos)....from memory took out the rear turbo n manifold out first then the fronts...getting it out was difficult. putting back was in reverse order. Just becareful not to bend your water lines underneath n oil lines for that matter. good luck make sure u have alot of space as well! did mine in single garage on stands. Taking the passenger wheel off made for some space as well when getting underneath. hope it helps.

Has any one installed new turbos in the factory location with the engine in the car? Mine is a 32 gtr.

I swapped the dump pipes not long ago which was a nightmare. Any comments would be great as i got myself some gt 2860r-7s last week.

If you can do dump pipes without removing turbos you should be able to do turbos with engine in the car .

When you strip all the pipes and you have only manifolds and turbos left, the hard work starts . A set of 3/8 sockets extensions and unis are good .

Unbolt the oil and water lines from the turbos ( the 2 banjo bolts from each turbo ), unbolt the front turbo ( bend the locking plates back to undo the 4x13mm nuts ), lower the turbo a little so you can get to the bottom manifold nuts with a 3/8 drive extension, you feed it through the gap between the turbo and the manifold . Carefully move the oil and water lines, bend them low not near the benjo , remove the front manifold then the front turbo with the dump should come out. You don't need to remove the power steer pump but you may remove the oil tank out of the way . Do the same with the rear turbo .

I assume you would have undone the front pipes, the turbo brackets and oil returns from under the car first.

If you don't have a workshop manual download one its good to have in case you get stuck .

The hardest part is when you install the turbos ( in the reverse order of course) to start the oil and water line banjos( rear one is the hardest) thats why its important not to bend the lines very much and not near the banjo bolts .

The job can be done in about 5 hours everything going well and if you are experienced, allow double that for you and after a few skinned fingers and a lot of swearing you will be fine.

A hoist helps so you dont lie on the floor but you can do it without, a magnet is good and make sure you cover all the holes so you don't drop anything in there .

i'd reccomend making your own so they will be perfect. buy the teflon inner stainless covered line from earls, get the banjos and any angles you need too. take your old lines in with you so you can get a good idea of the type of fittings you need and the length of line too. it's a good idea to cover them with the flame guard/heat guard stuff too. having flexible lines also makes installing/removing the turbos easier.

      Yep, yeah would need to do the flywheel although the 6 bolt NA clutch can handle a 20de if just wants to replace the stocker.

      No it's fine. Heat sleeve is a thing. With oil running through it it is unlikely. Engine off heat soak can be a thing though. There is no way that you have a leak through the hose. That has pressure behind it and any small hole will turn into a large one in very short order. It is so much more likely to be leaking from the connection.

      Really? That's piss weak. I didn't know they hobbled the shitboxen that badly. OK. So probs need to buy a flywheel too. But that's not too bad.

      Unpeeling the Orange

      By sunsetR33 · Posted

      Hi all. I already posted some newbie-ish questions here and there but this will be my first "big" post. Last summer I went and fulfilled a kind of childhood wish, because I just thought I needed this experience in my life no matter what. The car I bought is a mildly modded 1995 BCNR33 Vspec. It was repainted to a metallic orange color all around and it had all windows reseated. Not so well done black respray in the trunk and a metallic black in the engine bay. From outside it looks very nice except for a minor paint error on the roof and the rear spats needing new adhesive tape. The inside is pretty clean and no broken plastics, missing or faded buttons. Even the adjustable mirrors and trunk antenna work like a charm. Despite a moderately long list of issues I don't (yet) regret buying this car. Most mechanical problems are just due to age, like worn rubbers here and there. The underside sadly has lots of corrosion, especially to the back. It looks like it either has been driven in the winter for a while or it lived near the saltwater in Japan, the rust is nothing terrible but it'll require to be looked after. Mostly panel gaps and all the mounted components underneath are a bit crusty, but I don't think anywhere has progressed so badly that there's going to be holes. Front right jacking rail is crushed and needs some care so it doesn't develop into a rust crater at some point. Worst part is definitely the strut towers. I thought they looked fine but after taking off the strut bar I noticed that it actually started bulging up on the passenger side. Probably would have passed on the car or negotiated down by some thousand Euros more if I had noticed this before buying, but here we are. Trunk area also has signs that there was a water leak to the interior once but nothing too crazy, I guess lots of Skylines had this at some point. As for the list of (known) issues, I'll try to make this compact. I hope the coloring is self explanatory. Mechanical: -Various busted or soon-to-be busted rubber bushings and ball joints. Will replace ball joints with OEM or better and bushings with polyurethane where possible. -Shaking steering wheel at above 80kph -downshift from 5th to 4th is a bit crunchy unless I rev-match, might just try to renew the shifter assembly, but it's not a priority issue -tailshaft centre bearing could use a replacement, is it worth going 1-piece tailshaft as it doesn't look too fresh all around? Chassis: -underbody corrosion on many spots and in hollow spaces, needs to be treated -corrosion on many bolts, hoses, lines, suspension components, subframes, will be treated when replacing of the bushings is needed as time goes on -strut tower top panels and some of the surrounding panels are rusty, so needs fixing. Will look into doing this with a buddy in the winter, otherwise bite the bullet and pay a professional -driver side door is misaligned to the body and needs to go a slight bit more inwards -both door windows are misaligned and have an airgap where the window meets the door at the B pillar -The Aerocatch latches for the bonnet have locks but no keys, need new keys. -driver side door window is kind of gritty and could use a polish -damaged jacking rails and front frame rails, from people lifting the car the wrong way, might have this fixed by a bodyshop Electrical: -Nismo tachometer is just bouncing and displaying nonsense, supposedly worked fine when the stock ECU was still in the car -An old Greddy boost controller sits on the dash which will be removed as it servers no purpose anymore. -a led segment rpm gauge is on the steering column, will probably also be (re-)moved once the Nismo tacho is working correctly -there was an attempt to make the sound system better by the previous owner but it was just inducing noise all the time, ripped out the amp and filters in the back, no music for now -trunk antenna goes up as long as the radio is on regardless of the mode, I want it to only rise if I choose Radio specifically or per switch -3rd brake light is a bit dimmer than the taillights but everything was converted to LEDs so mabye now it just seems dimmer? -reverse light flickers, have to test if that behavior changes when I fiddle with the gear stick. Hope I can get around changing the switch. -Left side taillight, blinker section has minor water intake and is humid after washing. Other side has a hole in it, probably for that exact reason. I'll probably reseal them entirely and plug the holes. Engine: -minor coolant drips on one or the other hose -rear turbo leaks oil onto the exhaust making the car essentially undriveable due to fire hazard -Oil filter relocation kit has an oil drip at the Dash lines, will probably make a new connection there and tighten real good and pray -throttle body assembly is slightly stuck for the first throttle pedal input after sitting for a while I'm always open to suggestions and advice from more experienced people, I'm sure half of this list is easily dealt with and just requires some time and effort to sort out properly. Once I have some proper pictures of the car I will post some in this thread, I just have to remember to take some more once I get the chance to. Will post updates when I have news on anything, I want to try to keep this thread as kind of a logbook as well. Ultimately my goal for this car is to just enjoy it. An engine rebuild is probably going to happen sometime as well, because it is old after all. It will never be fully new again, I am just not that rich. But I want it to look good, work well and not rot away while I drive it. I'm probably gonna spend a lot of money on this journey, hopefully not an unreasonable amount.

      braided lines for the turbos

      By sunsetR33 · Posted

      Hi all. So one of my major issues at the moment is my rear turbo leaking oil on the exhaust (and the general area). I presumed it was the rock hard super old drain hose, which it was not. So now I am in the midst of removing the rear turbo to get access to the banjo bolt that goes into the turbo oil feed. As one of the previous owners accidentally? tore off the OEM oil feed hardline that reaches behind the turbo, they ran braided lines directly to the turbo, presumably PTFE. Now, regardless if the line has rubber or teflon inside, is it just generally a bad idea to do this? I imagine these lines get quite hot being between the engine, turbo core and exhaust manifold. I suppose it's not too far fetched to think the line may even have melted. I'd love to hear your opinions on this as as the replacement OEM hardline piece is 130 per unit. And cutting open the currently mounted line to see inside will mean I just have to get a replacement either way. So far I am hoping maybe the bolt just loosened or (god forbid) they forgot one of the crush washers.
