If you were given for free...

[exitspeed]

what would you take a Sr20det or a Rb25det? Swap all included, no costs to you at all.

PS. I'm not giving any away I just want to see what you guys say...

I'll take the RB please.:D

[Bill Roberts]

Wow, what a trick question!

Here is why:

Most SR20DET's have lower miles..meaning they should last longer.
The RB25DET runs smoother, is a 6 cyl and IMHO is a better built engine.

Rebuild for the RB is MUCHO Denario.

RB is the better engine. IF the RB had 80K miles and the SR had 10K miles, I would pick the SR every time.

The choice has to do with indivigual selection. A really clean SR will beat a higher mileage RB in value..as in Maintainance expense.

I also would be very careful in hearing both motors run even if they were free before I started the swap. Nothing worse than installing an engine with great compression to find out it has a rod knocking or a foul camshaft or valvetrane.

If equal mileage..RB baby!

[Dousan_PG]

depends on a variety of factors
mileage
compression
year
turbo condition
etc..

[exitspeed]

ok say we were talking same miles, engines both run smooth, etc.

[Dousan_PG]

yeah but what type of SR?
s13 chuuki/kouki
s14 zenki/kouki
s15

rb?
the various years (i dont know enough about them)

[Spec_v5150]

Ill take the RB anyday of the week. I personally would cut my losses. Even if it needed a rebuild, I didnt buy the engine. And why would the SR have lower milegae. The R34 DID come witha GTS-T and what year was that last made.....I dont recall, but it was recently. Last 3 years...not too up on my Skyline history

For my S13, I would go with the SR. Just because Its made for the car, and the balance ir right too. Im not a HUGE power guy. All I would look for is about 250-300 WHP, which is pretty easy with SR. Damn Enthalpy made 539 RWHP on a stock bottom SR, WOAH! I would go with S13 Kouki black top motor. This way I can retain power steering AND A/C because I do care. Im pretty sure you cannot retain it on S14 SR in S3 chassis, otherwise Id go with that motor even though I dont care for the variable timing stuff. Just cause it would be newer.

Yeah i agree. I dont really care for huge power. I would prefer i decently powered, well handling car. If you get the RB, it would put more weight upfront, upsetting the balance abit. If I were into drag racing, then maybe the rb would be a better choice.

The RB isn't much heavier (I know its 50lbs heavier than the CA...not sure about the KA tho)...nothing a CF hood and relocated battery wouldn't cure.

[nissan slut]

last time i checked the RB is more like 180 over the KA including the transmission. if the SR has better gas mileage, then i would pick it. what has the best gas mileage between the CA, KA, SR, and RB25?

[zenkiDori]

S15 SR20DET with S14 transmission.

[Jsquared]

RB... then sell it and get an S13 redtop and however much goodies i could with the leftover money :D

i'm more about handling than big power, RB puts in more weight, all of it over the front of the car. i would be perfectly happy power-wise with 300rwHP (basic T28+support setup)

THANK YOU. I think people just shout that out without knowing. I cant tell the difference from the KA to the RB. And you can do things to make up for it. I removed the A/C. I will eventually move the battery to the rear. Also I will be getting a CF hood as my stock hood looks pretty grotesque underneath due to my fabulous cutting skills;)

Generally speaking the lower displacement enginge should have a higher mpg, but the boost is going to play a factor, and the condition of the engine and fuel system.

I would assume the CA18DET would have the best economy.

true. Boost plays a big part as does driving style. I go through ALOT of gas. I drive like a bat out of hell though. IF you are want good mileage, dont get a swap or drive slow. To me gas mileage and a swap are oxymorons

[240silvia]

Hmmmmmm, I love SR's but you run across more SR's then you do RB's. I think I'd have to go with the RB.

[weirdstyles.net]

Id go for an 1UZFE.....tempt fate with an 8
