hi guys

i am in the process of purchaseing a 25/30 - ill basically but using my current bolt ons on the new motor -

my question is when swapping the engine over - should i remove the manifolds then pull the motor out?

same with installing will it be easier to fit everything including manifolds then put the motor in?

i am planning on removing the box the same time and swap it over and install the box on the new motor and fit it in?

any opinions and advice on this? people who have done it - have any tips? -

i havnt done this before by i am getting help from a mate who has done this many times - not with a rb tho..

Leave the manifolds (both sides) on the engine when pulling it out and put the manifold on the engine before you put it back in. It's a prick of a job to do in the car. Not impossible, just fiddly. So much easier to do when you can rotate the engine and see under the manifold for hoses, etc.

You can pull the box out still attached to the engine. It's a bit tricky with a GT-R but a non GT-R a lot easier due to less weight and bulk. Just make sure you remove the shifter from inside the car first and the wiring from underneath which can be a bit tricky.

With your air con and power steering you can just remove them off the side of the engine and leave them to the side. Don't disconnect any of the hoses.

Make sure you remove your radiator too.

If you leave the tranny in and just remove the engine put a jack under the trans to take the weight.

Good luck!

No offense intended but you need more than "point in the right direction"

swapping engines is a big job and I STRONGLY suggest you get someone experienced to watch over/help you out as its real easy to make expensive mistakes

The head sits nearly 40mm higher with the rb30 block under it. You can slot your engine mounts a bit, but the exhaust wull still be a fair bit closer to the floor pan. Usually there isnt much clearance so it will foul if you don't do anything about it. Have a look at how close your exgaust is at the front and see if it could go straight up 30 to 40mm. I made a 45mm thick flange to space it down, which also moved exhaust back a bit due to angle of the flange but that didn't matter.

Get a load leveler for the crane.

You need a new bit of hose for turbo oil drain due to taller block.

load leveler is why i was asking aboutt he crane - but now i understand.

i am planning on uprgrading and going better lines but thank you that is on my list - (list is getting bigger)

Read the thread mate, they changed his mind.

If i were doing it, i would be getting all the info i could. Not just scanning thread titles and ignoring the content.

sorry mate i looked straight over the point you were making - as i had pinned that mini guide -

very helpful as i want my box to come out with the engine as well -

thanks peeps starting to organise a long list - i have plenty of ti,e as the engin arrives mid january and will slowly finish bits off. i wont be doing the swap till proble may i think due to power cruise end of march (leaving my current engine in for this) then my first child arrives mid arpil - so i am in no rush for this job plenty of time for planning and learning -

I've done it before with a rb25 engine swap not a 25/30 but process would be pretty much the same. I did it at home in my garage. If u need a hand I should be able to give hand if I'm free.

It's not as hard as ppl say and there always gonna be people who tell u other wise on forums. Just make sure u have lots of little containers that u can put all your bolts in and label them that's the main thing I think.

    • Yeah, sort of blurring two different things together, aren't we? I just meant O2 feedback closed loop. I used to have a 0-1V LCD meter on my dash, wired directly to the O2 sensor signal. So you could easily see what it was doing. Normal running it would flick back and forth nicely. Slow down to an idle and it would keep flicking, as the ECU tried to servo to maintain stoich, but it would slow down as each swing happened until it would stay at one end of the scale. As I said above, the sensor heater is not enough to keep it hot enough when there is also little heat in the exhaust flow. Give it a blip and it would start swinging again, then peter out again. Meanwhile, idle speed control would run just fine, because unrelated.
    • It's not even O2 feedback, it's just simply when the ECU sees the closed TPS signal for whatever reason the idle will start steadily dropping until the engine dies. With the TPS adjusted to not trigger closed TPS it will idle at some ridiculously high RPM and something like 6 degrees of timing. In the absence of getting eyes on it personally and a lot of quality time doing diagnostics I couldn't tell you what the real problem was but it was interesting nonetheless
    • Oof. One of my mates has an R34 GT-R that he initially was a "I want to go twins for response and convenience" on his stock 2.6 with Kelford 272 cams, but his friends are pests and were always in his ear about their place being in the bin.   Eventually one of the 2860-5s decided to add it's own input and force his hand, so he conceded and went for a Pulsar 6262G ("G35 900") with T4 0.85 hotside.    Here's an overlay of the results, same cams, same stock bottom end, same boost, same fuel, just from a pretty tidy 2860-5 install to a Pulsar turbo on a 6boost maniifold on BP98.   Worth mentioning here, it may seem like a dead horse thing but the dyno plot doesn't tell the story of how much better it is to drive - transient response has completely changed the car, he used to have flat foot shifting to stop it having to wind up again on gear changes even at >7000rpm... now it builds boost faster than that even short shifting.   It's 100% transformed the car before you even consider how much better it holds on: Pulsar and Garrett aren't the same, but from our experience if you're just looking for a better drive and the ability to make the same or more power I think the divided G30 770 would probably be the smallest I'd go to.
    • Great work Duncan, any events local you will give it a test once all done?
