Engine Swap

[Reese69]

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!

awsome thats what i was hoping i really didnt wanna take the manis off in engine bay - over doing that -

well thats good i just really wanna make sure there was not little tricks or hidden fiddle things to stuff me up - (that normally happens to me)

seems fairly straight forward which is good

[Reese69]

anyone on here done a basic engine out engine in wright up - ?

i never done it before and might need to be doing most on me own so need all the help i can get.

[Reese69]

anyone here done a engine swap at home?

what crane was used? what should i be looking for in a crane? few people say the ones from super cheap and repco are the same just different brands and are both fine-

point in the right direction would be nice

cheers

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

[Ben C34]

Seriously, if you are stuck at what crane to buy be prepared for a hard time with the swap.

By all means give it a go, and good luck.

What's your plan for your exhaust? Most I've seen won't fit with the extra 38mm deck height of the rb30.

[Reese69]

i actually am getting help thanks for the concern -

i actually made my self sound stupider then i am, which has been cleared up - but i didnt edit the post -

what do you mean buy exhaust? i know it is higher, but i thought this was only an issue with the stock intake manifold(which i aint using)

what have i missed sorry?

thanks to the ppl who have helped

[Ben C34]

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.

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.

[Reese69]

hahah i agree thats what i will be doing labelling stuff that im not sure about -

if i get stuck or my mate is unavalible i may take you up in that offer
