240sx Swaps SR20DET vs. RB25DET

[UndftdSole]

im assuming you have an s13? doing a swap you must do all the wirings and such. that will be time consuming. also most of the problems after the rb25 swaps in s13 chassis are either tach or speedo doesnt work or even both. you must do a lot. if you dedicated into swapping rb25 in your s13, be sure you have lots of funds and patience. thats my .02 cents

The key is I want a pretty much stock engine with power thats why I am thinking of choosing the 25. Yes I know I will be needing brakes and a suspension set up but I dont plan to be driving crazily at the beginning because I want to learn how to react to the heavy nose.

For the money you'll be spending on a stock RB25 swap, you can have a SR or KA-T with more power output than the stock RB25. As long as you get a good ecu tune for your motor, it'll be just as reliable as stock and probably have better gas mileage than the RB25. I spent $4400 on my SR swap and was able to put out 270 whp. If having a RB is really important to you, then yes, I'd say it's worth the money. But I if you're just looking at the 220 to 250 whp, the SR and KA-T's are better bangs for the buck.

Alright I have to save up a little longer but I want to make sure that I can have all the parts and even the maintenence parts that need to be replaced to prevent future problems and costs but I was thinking Front Clip 2600Mounts depends on producer 350 - 550Harness depends on who will do it 450Radiator 100-400Electric Fans 50-350Timing Belt 140Clutch 160Flywheel Water Pump 70(stock) - 265 N1Plumbing Lines Driveshaft 305 shaftsmastersAnd if anyone could else name parts that I would need so I can get a close estimate than save a grand over that

[Romeo_rus]

I would add front pump seal and rear main seal

yeah,,,but OP thinks that KA-T is unreliable! You just have to know what you're doing.

Thanks yeah I think the RB25 might be too far out of reach right now I think I might go SR sorry for changing my mind so many times I was just thinking about how I heard that the SR20 gives the car good balance seeing that it is lighter also I don't plan on messing with the engine and knowing that the aftermarket is huge on those motors I think that is what finally got me to make my mind.Thanks appreciate it.

I'm doing rb25det swap into my s14 right now... I've spent so farmounts 250mount bushings 80fmic 105swap 2000harness 358driveshaft 305

and it looks cheaper than SR20det (on ebay) 3200+ swap

what mounts did you use and how good are they. I was going to go with McKinney but 250 sounds better than 450

da** this thread is old
