*disclaimer* that is my opinion. i dont care if you like it or not. the rb20 and sr20 make the same power, have the same potential but the RB is harder to get parts for, more expensive parts, harder to get info for. if your gonna have to deal with owning a RB at least get an engine that will outperform the SR20.

SR > RB20

Ehh... it just means you have to go to autozone and pretend you have another car...

You can get most serviceable items without to much of a hassle if you know what car you can get the part from...

I don't regret not going SR...

I want a 26... but I don't want to get rid of my 20... guess I'll have to build another car...

When I have trouble with my RB20... Then i wish I'd gone SR.

When it's running well (most of the time) I am glad I went RB.

That and pretty much any time I can hear the exhaust note it reminds me that the RB20 > SR20.

SR > RB20
About the only Rb that will really kill the SR20 would be the 26. The 25 is good but I'd rather have a SR20 over it. *disclaimer* that is my opinion.

I too must disagree. if i cannot have an rb i'd go CA. I would never touch an SR mainly because i hate distributors and the limitations they imply.

um only a VERY few VERY rare SR's have distributors.

95% of all s13/s14/s15 SR's are DIS just like the rb.

aye.. i like my angle sensors to only have one way to go in as opposed to 50 ways to screw it up lol : ) if it wasn't for that i would have nothing against the sr bandwagon (save that it is a true bandwagon and all that implies)

then again... i'd take a 4g63 any day over an sr20. say... to bad i don't have more knowledge/tools... that'd be a fun swap with a rwd starion/conquest trans

A freind of mine who runs a shop in Tampa used to have a 1977 dodge shadow(made for dodge by mitsubishi) with a 4g63 mounted to a mitsubishi mighty max transmission running it rear wheel drive.....good god that thing was quick,high 11's with a small 16G turbo,a frontmount and just a few other bolton's....it was pretty crazy to see something like that back in 1999.

the only thing I hate about owning an rb20 is that people say 'you mean sr20?' and then you have to explain what an rb20 is. I got my front clip for 1,400.00!!! it was a 91 gts-t type M with 83,000 KM and it runs extremely well. everyone says it throws off your handling, but i cant feel a difference. of course I went from auto to manual and the weight lost from the auto tranny probably compensated for the weight gained from the rb:) Parts availability is the only looming issue i am not looking forward to. i would love to pick up a cheap blown rb20 to have a few spare parts like starter, coil packs, etc..

plus a rb looks waaayyyy more impressive than a little ole SR20

Yeah... cost is a big part as well. I had mine professionally installed for close to what an SR costs before shipping!

The RB no only looks way more inpressive, but the sounds are to-die-for!!!

I find myself looking for close buildings/overpasses, etc... just so that I can hear the sound bounce back to me. Its so sweet!!!

you don't know sweet until you hear the RB through a buddy club spec II exhaust. right now Carl H's is on my car i'll get a vid soon if someone can host it.

rb looks impressive... doesn't screw with handling much if any and sounds awesome. plus if you make sure to replace all the maintenece parts (water pump, timing belt/pullys etc...) and you get a good motor to begin with, it should be as reliable as anything out there... at least in stock form.

I'm actually debating whether to go RB20 or SR20, so threads like these help alot. But there seems to be equal pros and cons for the both of them, so i'm still so confused.........

well i personally like the look and sound better but it seems like its an older engine so i keep having problems with mine but when its running good i love it just it sucks when its fu***** up but im still working the bugs out of mine i think if id gone sr20 i would have had less problems and been able to make the same power so just look at the pros and cons

I like rb's and sr's. To the SR side, everything's easy, timing chain instead of timing belt, easy to run front mount, weight's not an issue, and all the guages work correctly. I LOVED the sound of my Rb with just a 3" in/out magnaflow ( anything but an n1 style ) cause it was quiet and all you hear is the turbo spool. My rb was $900 from Jhot and it came with the side mount, piping, and a 3" downpipe. But as far as running a front mount intercooler, your best bet is to spend $$ on an intake manifold. So that kinda sucks. Also factor in motor mounts if you go rb20. RB20's wiring is easier than sr (not like either are rocket science though). When you want more power though you're buying 6 injectors instead of 4. All in all though. You'll be happy with either one you do. My best advice to you is, establish how much power you want, make some trees with prices of parts, options on motors, turbo's etc, and see what works best for you. Personally I'd save my money on what I really want, than settle. You'll be happier you did. :D

My RB20 doesn't seem to have any problem dealing with comparably equipped SRs. I love the RB20 haters, they are fun to listen to. Heck i still have the stock front pipe and cat on the car for crying out loud

If you want a turbo 4cyl....go KA-T. I would go KA-T before i went sr. you can pick up a cheap ka, build it to what you want and it will make power just as good, if not better than a SR, or rb20 for that matter.

I would go both RB20 and CA18 rather than SR, can´t stand crappy rockers and cam chain. Besides that they got iron block.

I would never throw it away if the car had SR as stock but when you talk swap you can always pick the engine type you like.
