Nggggggggggg.....comeon at least give this guy a chance...he IS trying btw....more that can be said for most of the car owners on this board who are too soft to try doing engine changes (yes most of you!)......
In not a very good order, but still.....This is from when I put a RB25DET into a VL Commodore
Bits required (VL Commodore)
1) RB25DET engine, loom, and 5 speed gearbox --> R33 unit....do not use the RB20DET gearboxes as they are a much smaller unit. Also the R33 units use a diffrent flywheel and starter motor (bigger/heaver) compared to the smaller RB20DET boxes (MF5) All the GTR gearbox is a MX7/R33 2.5 litre gearbox with a 4WD transfer case.. The Nissan Navara 4WD has the same gearbox as the GTR skyline, but diffrent external cases etc....a good source of spares when you MX7/R33 unit shits itself
2) Intercooler...VL's dont have 'em
Well thats it for a VL.....everything fits on the factory mounts.....for a S13 you need a R32 Skyline sub frame, with attached engine mounts. You may also have to modify your tailshaft (depending on what gearbox you had in your car to start with)
Order to do stuff.......
---------Both VL and S13---------------------
1) Stop car, get out
duh....
2) Decompress engines fuel system. This is done by removeing the fuse from the fuel pump and starting the engine....wait to the engine stalls (DONT FLOOR THE ACCELERATOR WHEN DOING THIS) turn the ignition off.
3) Disconnect and remove battery
4) Disconnect fuel hoses from the existing engine. Clamp both the sender and return line off with hose clamps....
5) Disconnect and label (and label and label) old engine loom. Punch the old grommit out from the fire wall and feed the old loom through. Unbolt the old computer and pull the loom out of the car.
6) Disconnect any other engine acc...eg Powerstearing (remember to put a bucket under the car to catch the fluid!) and empty the radiator. I recomend you remove the water pump off the old engine and put it in a bucket of coolant so the seals in the pump dont decay.....
7) Now jack the car up on the hoist ( or go down a pit....if your still keen axel stands......) and disconnect and remove the transmission crossmember. Also remove the exhaust system from the headers back. I recomend you remove the CAT at the same time if its in the way. Also remove any wires to the gearbox (in the case of a manual, the Neutral switch and reverse switch) (in the case of a manual it should be one big plug that comes out) and speedo sender. (If its a cable) also disonnect your hydraulic clutchslave cylinder....
8) Working inside of the car remove the gear selector coverplate, and disconnect the gear stick boot. You should be able to see rite thru the floor to the gearbox by now. For a automatic you need to unscrew the selector and unclip the rachet that goes to the trans selector (metal rod). Then you haveto remove the plate under that which is screwed/rivited into the chassis.....remove this (if rivited drill 'em out)
9) Nows a good time to check if you removed everything connected to the engine....dont forget things like heater hoses (hard to see) and vacume lines....
10) check again.....sorry very important
been there done that....(good story to go with that.....)
11) Now you can unbolt the engine mounts from the BOTTOM........
12) wrap a old seatbelt around the old engine lift mounts and hook it up to a engine crane....
13) Slowly lift the engine out of the car, with a person under the car making sure that the tailshaft yoke came cleanly out of the gearbox.......(Nissans are not bolted to the trans)
14) Remove engine and put it on the ground. Now hook up the old engine loom (which you labeled of course
) to the old engine so you can sell it as 1 complete unit
15)--------------S13 ONLY--------------
Disconnect the stearing rack, swaybars and anything elese you see from the front subframe. Unbolt the ubframe and gently lower it to the ground. It helps if you hook the engine crane to the subframe........
Install your old stearing rack on the R32 subframe.
Now install the R32 subframe and bolt up you swaybars etc. Also hook up the tie rod ends (stearing rack) to you front struts
15)-------------VL Commodore ONLY----------
Nothing needs to be done...the RB25DET sits on the old mounts with no mods
16) Install new engine. Basically a reverse of what we did before, lower it in slowly, make sure the tailshaft joins up ** (see bottom of post) bolt your geabox crossmember in, and hook up your wires. Also make sure the gearstick comes up through the hold in the floor...
17) bolt up engine mounts....I recomend you pruchase new ones evertime you do a engine swap, buts thats just me...
18) Double check your wires......I normally make a new lom for scratch so I know everything works....
19) tripple check your wires......hook up aircon, power stear etc. Bleed your power stering unit.....
20) hook up your fuel lines.
21) Bleed your clucth and make sure its working.......
22) Reinstall battery......
23) Change oil in new motor, fill motor with coolant...remeber to take the top bleed bolt of your new RB engine otherwise it will blow a head (YES THEY ALL DO THAT!)
24) disconnect ignition system.....(eg plugs)
25) Turn ignition on (dont start it!!!!!!!) listen for you fuel pump turning on and then turning off (when pressure has built up)
26) crank engine over. this makes sure you have oil in the engine when you fire it up for the first time
27) re connect plugs
28) O.K now you can fire it up!
29) If engine goes great...if not, check spark, injectors (tap them with a hammer if the engine been sitting for a long time unused....gently!)
30) Sit back and have a beer, knowing you are a REAL car person, not some rice boy wanna be.....
**I'll explain how to do transmissions tomorrow, tailshafts, auto to manual conversions tomorrow....
