hey all, im extremely interested in purchasing a cefiro with an rb20DET manual and shoehorning an rb25 (engine and gearbox)with mods in its place. I have seen a few with this conversion done, but i cannot find a thread discussing the costs involved (minus engine) and what is needed to be modified in order for this conversion to be successfull? Is it even worth the expense? does anyone know what the weight diference is between the two engines? any info would be great, thanks guys!

it should pretty much bolt straight up... :S

if u get 25det gearbox also then only slight mods are needed to get this to fit in the car (check substitute parts section as there is a write up on this)

just need to change the loom and computer to suit - possibly auto electrician to wire up other complications

... but realisitically it shouldnt be that hard to do...

Gibbau - Give me 2 weeks and I will give you all the answers you require :D Currently doing the conversion as we speak! SEE SIG :(

But there are so many variables that can effect the costing of this conversion -

1. Are u doing the conversion urself or paying a mechanic

2. R33 gearbox, new one or 2nd hand

3. RB25 ECU or piggy back

4. Various sundires - New timing belt, filters, machining flywheel, flushing radiator......

Really depends on whether u want a quick "Wham Bham thank you mame" or a setup that will last!

For example, including cost of engine & gearbox + a lot of other add-ons, I am budgetting for around $8000

Check my thread, "Should I 1JZ in Cefiro' for a bit of an idea what i am doing!

Hi

If you want an RB25 Ceffy, buy the rb20 NA auto Ceffy currently on ebay for less than $5,000 and modify.

Extra cost will be brakes (but you need to go to R33 anyway) and diff. Oh plus hand brake, console and pedals.

Agree it is expensive, although, I did the front mount, 3"exhaust and front bumper at the same time!

Basically have to do water pump, seals and timing belt no matter what and suggest you do exhaust manifold gasket at the same time. All builds up. Also gearbox yoke (need from R33 tail shaft) and fit to tail shaft and speedo drive (as they are different, people use R32 GTR or Navara)

Good luck

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
