Is it as bad as they say? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I'm looking at a s14 swapped with a rb25 and it's fairly stock for the most part. I was wondering if it is really that hard to get parts for? Also was wondering if it is a reliable motor? I always here two sides to reliability or turns into someone saying get a different motor because they like it better

Alright... its easy answers...

1. It is not difficult to get any of the parts for the engines now days as shops all over sell the stuff. Just not something you can rely on as 1. there are very rarely any trust worthy shops now days and 2. you will almost always have to get the parts shipped to you. Make sure to buy extra of stuff that is known to go wrong or break...

2. Reliable question is a dumb question. Build it correctly and it could be reliable, be cheap and build it crappy, could not be. stock is chancing it. No one will know about your specific engine unless they look at it and even then, can never say for sure. All engines blow up and all can be reliable. Just depends how they are taken care of and built...

3. You hear* (< This is how you spell it) two sides and you ask a forum that will just do the same. Go with it if you want too or go after the engine you want. Yes, they are known to blow up just like SR20det's but yet you see people get them anyways. So do KA, LS, etc etc. Basically what was talked about in #2...

and 4. People who say to go to a different engine because of whatever are dumb when its a post surrounded around a specific engine. If you want an RB25de or det or whatever and have already looked into other engines, then something about the RB makes you want it more than the other ones so just get it.

Best of luck and dont be dumb running 40lbs of boost on a stock block... tip to save the engine .

"Go with it if you want *TO".... Shouldn't correct someone when you can't spell things correctly either.

Good tips about the RB and to your post count Care to post something useful or is that too difficult for you and your perfect world? Having an extra "o" or one too many can be seen more as a type instead of a actually incorrect spelling.

Also another thing to note is if you are going off of videos, try going to events to hear the engines as well as see how others have done their swaps. Often times, if you find the person who built the car, they are usually always happy to talk about their build and boast per say. See what issues they run into often as well so you have a better idea. If of course you are not set on the RB.

Having a reliable RB25 is very simple. Fix it forward.

Get the starter, alternator, and CAS rebuilt. These items are 20 years old. They are guaranteed to wear out at some point. Rebuilding them adds another 10 years of trouble-free service. Now you won't need to worry about part availability or extensive shipping times because you won't have broken parts!

Replace those crappy coolant hoses under the intake manifold. They've seen more then enough heat cycles. Their days are numbered.

Inspect the coilpacks for the common insulation heat cracks. Better yet, replace them with Splitfires or LS coils.

Inspect and replace the plugs, timing belt, and water pump according to the maintenance schedule as you would with any other vehicle.

If you intend to rape the rev limiter from one end of the track to the other, get the extended oil pump drive crank collar installed. Not necessary if it's being used for daily driving. My RB hit the rev limiter at least once a day for three years and my stock oil pump drive showed no damage at all from the short crank collar. The only pump failures I know of, happened because extremely abusive owners beat the everloving dogsnot out of their engines.

I drive my car 80 miles roundtrip every single day and wouldn't hesitate to drive across the country.

Thank you for this. Definitely will take your advice and no plan to rape the limiter. Mine will be a fun daily driver for me that of course over time will get built up a little. Also in the car I am looking at the blinkers & horn do not work.Nothing shows up on the cluster & doesn't make the clicking. Was wondering if anyone had a little insight on what that could be ??? edit he said hazards do not work either
