yup done heaps, oem A31 or R32 works fine.Coolwhip wrote:I've used all mounting methods listed for various RB's. Just go OEM xmember.
how Important are these things to be installed? i am on a strict budget as of right now. (dont have a job) but will have money within a month or two. I have just enough money to get the rb in the car, n running. i have the walboro already. but everything else minus fuel pump, how important is it that these be replaced RIGHT away? would it be safe to drive as motor comes with new spark plugs n oil change wiht oil filter for about 1 month or so, then everything will get replaced.?? thank you, cullen.Joe wrote:I realized something today...I’ve been a moderator here for some time now and I’ve been telling people to search for answers to this question and never realized how scattered and sparse the information in.

Please add information or correct me if I make a mistake! This will be a sticky and possibly an article if it pans out well!!
First things first: any supplemental questions related to the swap (i.e. wiring) can be found here http://forums.nicoclub.com/zerothread/110509
What should I replace before the swap?
This is a very hard question because everyone’s budget is different. Not everyone can afford to spend an extra $2000+ worth of parts before the engine is even in. What I recommend to replace is:
1) Water pump
2) Timing Belt AND tensioner/idler pullies
3) Oil Pump
4) Clutch (possibly flywheel if you have the cash flow)
5) All accessory belts ( http://forums.nicoclub.com/zerothread?id=119087 )
6) Fuel Filter
7) Fuel Pump (replace with higher flow unit)
8) Spark Plugs (more info comming soon)
Those items will ensure you have a strong running engine for a long time. They are basic maintenance items that are overlooked by a lot of people who subsequently have engine failures.
I got flamed for this too!90240sxca18 wrote:well my choise is rb n sr. i have roughly 2500 in hand right now, and the motorset will cost me 1800. so i have the rest of that cash to spend on the MOST important things to replace right then and there, then within a month or two the others will be replaced. and fuel pump is already on my car. so any help, on what i should get first n formost. or something that has to be put on when the motors out? clutch is last. i want other things needed. thanks alot guys.
Hey yotik, edit your post to reflect, TIMING BELT. Don't want to confuse anyone researching these engines.yotik wrote:...cause i was too lazy to replace the timing chain. they recommend u replace the stuff because its easier to do with the engine out. you dont wana be changin the timing chain or oil/water pump while in the car...
rb and 2500 dont go to well together, when doing the swap the most important thing to replace is the timing belt, idler and t belt tentioner! all this will cost you at most 200- 225 depending were u get parts fromCoolwhip wrote:

You'll regret doing a RB25 swap on a $2500 budget... The NRRBA will welcome you with open arms
I am using my USDM OEM S13 DOHC gauge cluster, and here is what I did...usmctankmech wrote:How would you obtain and or make a Tachometer Adapter for the RB25DET?
Well considering you're probably in the US putting a JSPEC engine into the car when this engine was never included in any car sold in America, you can't just go to Autozone and tell them "hey i need so and so for my skyline." Most of the employees won't know what you're talking about because half of them really don't know anything about cars and just use the computer system.RBFAN wrote:This is great, clears up a ton of questions that I was going to ask. After reading about the rb swaps, I'm going to start saving. Why are parts so scarce for the rb?
