sr20 Reliability

Post by **Ice2CU** » Sat Mar 22, 2008 6:55 am

I am planning a swap for my 98 (240sx). I have been using my car as a daily driver and it has had no mechanical problems. Now, I know that if I go with a turbo motor, reliability changes. But I am most likely going to be running it at stock boost and not going to be driving it hard.

With that, how reliable is the sr20 for daily driving? - and - What is the fuel economy for the sr20?

It's been asked before. Anyways, SR20's are just as reliable as the KA. I use to commute about 30 miles one way daily with my first SR. Six years later and in the hands of my nephew now it's still running strong. He dd's it at 14 psi. My current 240, I dd it at 14 psi and I put on about 300 miles a week in it. The important thing is to get a good motor from a reputable place.

I mostly drive it normally, but even with pushing on it every now and then, I still get 25 mpg. Remember this is still at 14 psi also. My car dynoed 270 whp at 17 psi so I'm guessing at 14 psi I'm still driving around a 240 to 250 whp car that's getting gas mileage like a 125 whp KA24DE 240sx.

What are some shops you would recommend?

Thanks for your input. I am basically trying to weigh the pros and cons of going SR20DET or RB25DE with an automatic. What places do you recommend I get an SR from?

I don't have any experience with any of these shops, but you can do the research. I hear lots of good reviews for Heavythrottle, Enjukuracing, and the best pricing I've seen is from Japan Racing Engines. All of these shops are sponsors of NICO. Make sure you ask for pictures and for compression test results. If they're a good shop, they won't have a problem with getting you either ones. Be sure to ask the shop any questions or concerns you might have.

RB or SR is an ongoing debate on here and every other 240SX forum. From people I know and from what I hear on here. Most people end up spending on a average of $3k to $4k for a stock S13 SR swap. The RB on the other hand, I hear costs of over $10k for a stock RB25 swap. A guy locally, spent $19k for a stock RB25 swap!! Now imagine what you can do to a SR with $19k.

10k for rb whatttt????? theres a shop here that sells front clips for 3500 for rb25, i heard from there you use the cross member and mounts from the clip, then 400 bucks for costom drive shaft, like 250 for the wiring, and your done. thats a lil over 4K for bone stock rb25. This is just what iv heard but im pretty sure thats all you need.

Ask the RB25 guys if $4k was enough for their swap. Check out this thread. There's a reason why most people go SR or KA-T.

yea if were to list how much my sr costed me in the end total id be over 15k but just stricktley the swap was only a lil over 3. These guys are adding in the cost of there car and every modifiaction they did to it. But if you look at the essentials it was only motor tranny mounts and driveshaft. So if you get the clip and want to do it as cheap as possible i say it can still be done under 5k.

$5k, it's possible for just the bare minimum required for a RB25 swap, but all the little unsuspected stuff always adds up.

Post by **srdub-t** » Sat Mar 22, 2008 2:22 pm

oh of course i completly agree with you im just sayin that it can be done but who cares we got sr20s whitch is way betta n e ways

Post by **S14toRPS13** » Sat Mar 22, 2008 2:30 pm

LOL, and with $15K into your SR I'm sure you have no problem leaving a stock RB25 behind. I have no problems with RB25's. I just want people to realize sometimes it's not worth it to spend extra just to be different. Unless someone just totally has their heart set on a RB.

yea rb is kool and sounds sick but i dunno its just fun to be a fast 4 cyl cuz were always under estimated.

I know the RB is still relatively "newer" than the SR in America for a swap option. I have noticed that there are more places with more options for SR parts...plus overall, I know the SR20 is less expensive to go with. I do however have an interest in the RB25 because I am also thinking of going NA and just staying with an automatic transmission...for my own reasons. I am trying to find a good medium of performance, reliability, and fuel economy, without sacrificing my 240...and getting a Geo.

LMFAO!!!! "Ice To See You" Mcbain!!! kickas* name!!!.

Anways, RB's should be as reliable as SR's, and enigne is and engine, depends how you treat it, that'll tell you how reliable it really is.

I agree they are both factory produced engines. Both are built by Nissan so we know they are built as a superior engines both should be reliable to be DD.

DUFFMAN!!! One of my favorite characters. Gotta love the Simpsons.

But yeah, I agree that they are both capable. I guess it is just a matter of what I am into. Also I have been trying to find a 5 speed automatic that would fit an SR. That is my attempt to continue being lazy and not want to worry about shifting. Anyone know about that?

Post by **Ice2CU** » Mon Mar 24, 2008 5:59 am

Heh. Every time I mention the 5 speed auto, things go silent. It feels like a topic of taboo. I guess it is a pretty tough question to ask anyways.
