Hey all

I know this questions probably been asked a million times but...

I'm doing a swap between my rb25de for the rb25det

yes I know I can put a turbo on the rb25de with changing compression and all that but I don't want to be restricted in hp or anything else...

No I don't want to just sell my car and buy the turbo version I like the kit I got and it was a birthday present from the wife so yeah can't change the car...

I want/need to know exactly:

what is different?

what I will need?

what I can keep from the rb25de and put in/on the det

everything!

I plan to buy a complete engine but if I can get away with just buying the engine and other needed parts separately (only if it turns out cheaper obviously lol) then I'd do that

any help on this would be great!

Thanks

rip old donk out and drop the new one in. plumb all the piping up and swap the ECU's.

Should get you outta trouble, you will have to cut holes for the intercooler piping etc and run a better fuel pump than the NA version.

Just buy a turbo ecu, turbo injecotrs, exhaust manifold, turbo, oil and water lines, crossover pipe, turbo inlet pipe (inc plumb back and breatherpipes), bov and FMIC kit, and bolt it all to your current car, set your ignition timing to 15 degree's and away you go, on stock management you will make heaps of power- more than a turbo model would, just run like 9-10psi, which is all you should be running on stock turbop and management anyway.

Else, if you must buy the full new engine, sell me you N/A engine, so i can put it in the R33 with a blown TURBO engine, thats sitting in my driveway.... :( (and i'll just bolt all the turbo gear onto it, and make more power than it did before it died)

ok how much $$$ would you reckon:

turbo ecu

turbo injectors

exhaust manifold

turbo

oil and water lines

crossover pipe

turbo inlet pipe (inc plumb back and breatherpipes)

bov

FMIC kit

and how hard is it to change ignition timing

cause i can get a rb25det for about $2000

btw thanks for all the advice so far

will be cheaper and easier to buy the whole motor, I have a stock gtst ECu lying around so pm me if you need one (just remind me who you are and which thread or ill ignore it)

thanks a heap

btw id still like to know how much those parts will cost if i was to choose to go the +t way

how long is a piece of string?

go on ebay or whatever australian second hand trading site you have, and price it up from there.

buying a crate engine will most likely be cheaper.

that being said, im spending approximately the same amount of money on a +t build, except i'll have all aftermarket gear, a decent tune, fueling to support 300rwkw, and i'm aiming for mid 200's.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
