Ok so a friend has 2 complete swaps for sale one SR and one RB25

The SR has this going for it:

BC stage 2 cams
Dual valve springs
new headgasket
stock turbo
stock manifold
100%complete motor set
rwd sr20 transmission
s13 converted wire harness
Freddy oil pan
exedy stage 3 clutch new
S13 black top sr20det engine
motor mounts
stock rb25det fuel pump
a/c and powersteering included
cx racing fmic piping with bov FMIC and radiator


The RB swap is as far as I know stock.

Price is 3k including install for both.

Its for my DD so Im just not sure how much more hp that sr is pumping out (or can) becuz of the upgrades

[ZootedS13]

get the rb. it may have slightly less aftermarket support but with a few upgrades you can get 150hp more than a stock sr very easily.

[badbob2121]

if u can get a rb25 installed for 3k...JUMP ON IT!!!

this.

Ok good to know. I just didnt know if the SR upgrades already on it were worth it.

[numbnuts240]

is that rb an s1, s2, or a neo. has it been freshened up at all?

s2

New wiring harness other than that stock.

[numbnuts240]

i re-read the sr list, personally, i'd go with whichever is fresher (new gaskets, timing components, water/oil pump, etc).

[Eikon]

RB25 or I'll lock this thread!

ooh... actually, I just re-read your original post.. You said this is for a Daily Driver... I wouldn't daily drive an RB unless I personally rebuild it fresh from the ground up. They are harder and more expensive to maintain, and some parts can take you a long time to get your hands on... If you have to depend on this car to get you to work or school and back... Go SR.. easier to work on, more reliable (usually) and much easier to get parts for. You'll have a less stressful life with the SR.. You just won't be as fast or sound as good. lol.

[badbob2121]

^^^this is true, i have an sr and it is reliable and can take a beating...parts are everywhere and its easy to work on...plug and play turbo

[240SETulsa]

Lol ok I really like the RB but yeah DD so I guess SR for me. What would you recommend upgrading on that SR for some more power? I would actually upgrade my suspension first after the motor drops in just was thinking out loud for future.

Also do RBs just have a tendency to break more even if daily driven?

[badbob2121]

i would definatly work on ur stance before you do anything else.... but that is beating a dead horse

rb's are just expensive, very expensive...

[240SETulsa]

I was planning on working on the stance BEFORE getting the motor but, my motor is going out and I need to replace it asap so I can continue getting to work.

[badbob2121]

ya im not saying dont do the swap, just saying that stance should be your next investment after the swap....

[TurboSauce]

go with which ever has the least ammount of miles/has newer stuff on it.

[240SETulsa]

the rb25det has 60k miles fmic setup not sure on the sr. I just know the sr has a new clutch and HG. He said the RB has a firm clutch but didnt inspect it.

[PyR0NiAk]

Stock headgasket, or metal? What kind of motor mounts? Solid ones? Nismo? Some other brand? Modified RB ones?

[240SETulsa]

Well I dont think he has done anything to the engine so I would assume stock HG. Motor is from JHOT

Im finding out about the motor mounts.

[240SETulsa]

So I take it that means its probably a good swap

[PyR0NiAk]

sounds that way

[JDM Sil4ty]

sr for dd .. rb for respect and baller issues ..

[Seanzyyy]

get a shell and buy both motors

but on the real,
if the rb is in good shape,
i'd say get the rb.
but the sr is a great choice of course.
it's your call though man.

btw,
rb25's are just as reliables as sr's.

[Eikon]

Here's the other reason I'd recommend SR for the OP.. He lives in Tulsa.. HOT summers. A/C on an RB is possible, but challenging. More than that though... RB's run hot to begin with. You'll spend a pretty penny getting the cooling system to run efficiently and even then you'll have to worry about overheating it at intersections when it's 100* outside.

Go SR.. A/C is a snap, you can keep the clutch fan if you want, and it'll run much cooler.

Just a quick update

I went to the guys house and he actually had 3 motors. The SR and an RB20 and 25. We talked for quite a while about the motors and boy did he know his stuff. He actually said he preferred the rb20 over the 25 due to a crank collar issue the 25 and 26 tend to have as well as all additional wiring the 25 has in comparison.

He had actually JUST purchased the 20 and it had 38k miles on it and came with everything needed. He is even hooking me up with AC and PS! He even replaced the clutch on the motor. He said the motor was going into his second 240 (his project car) and as such it had a complete 3 inch exhaust setup and a full 3 inch screamer. The thing looked beautiful. He had a full FMIC setup and aluminum radiator to go with it and had mounted an RB25 turbo on the 20.

I already have dual electric fans so everything is going to be SWEET

Ill take some pics once everything is in place.

38k miles is just wow!

[Tyler]

i seriously doubt that it had 38k miles. RB20's i believe were first produced in 1986 and ceased production in 1991. thats older than most sr20's, which started production in 1989 i believe.

anyways what im trying to say is, if its clean, great. but seriously, a rb20 is older than a sr, makes about the same power, and is a harder swap. get the sr.

[240SETulsa]

This guy doing the swap is one of the top local 240 dudes. I saw some of his work (swaps and builds) s*** was clean and well put together. He makes his own motor mounts and everything and actually prefers to swap RB20s instead of SRs and RB25s (thinks its easier for him). Every motor he buys he gets a complete video of them doing the compression test.

True it does make the same power but an RB can hold more on stock internals than an SR can.

Looking at potential here.

Also RB20s and SR20s were made within the same time frame (well talking about the redtops not blacktops)

EDIT:
Silver Top RB20 - 1988-1993
Red Top SR20 - 1989–1994

I think going with a 20 is a very poor decision. If you want to go RB, at least go with the 25, it's a much better motor.. the extra displacement and the BEEFY transmission make it a significantly better value than the 20. Most 20's go for like $1500 max.. 25's are usually $2500 or more. I would never chose a 20 over a 25. That's a bad idea.
But.. your car, your money.. Good luck.
