If you like the RB20, than fine, whatever, but if you are saying that this forum is a waste of minutes of your life, then leave. Just like you think none of us have provided substantial information and are just typing opinions, all you are doing is the same thing.

SR20: 2 litre, came in the car stock in Japan and is what the weight balance and suspension is set up for. 50/50 weight distribution.

RB20: 2 litre, 2 more cylinders, more weight biased toward the front of the car.

You wanna build something nose heavy to make power? THEN SPEND THE FUCKING MONEY AND PUT A BIGGER IRON BLOCK ENGINE IN IT, NOT ONE THAT IS THE SAME SIZE. Everybody wants a steak dinner for Taco Bell prices.
Actually you are incorrect sir. The Mustang dyno reads lower than most others (ie. Dynojet). After I had it dynoed on the Mustang, I had it dynoed a week later on the same setup on a Dynojet and put down 280whp. As far as the "low" numbers, that was because I found two boost leaks later that day, and I had to take out 30% fuel correction on the SAFC to accomodate for the larger injectors, and the car still ran rich. I've already had my ECU chipped to make up for the correction, so now when I swap it to my S14 I can just use the SAFC to tweak here and there. The turbo is a T3/T4 with a .57trim and .63 A/R. I don't intend to throw a ridiculous amount of boost and go for stupid high hp numbers, I prefer my car to be well-rounded.

As far as your "50/50" weight distribution, that's the first I have EVER heard of that. Yeah the RB20 adds two extra cylinders, but the trans is also longer than the KA, thus making up for the front weight bias. I believe on NICO a guy had his RB20 S13 weighed and it was more like 48/52...gosh must really handle like ass.

And no I am not typing my opinion, I have actually brought numbers to the discussion. A "nose heavy" car? Honestly man, I have yet to see any hard info backing that up. Perhaps you could bring some to the table....

"Don't forget also over 300ftlbs. Many people from this forum were at the shop when it put down those numbers as well...This was on a dynojet too none of that mustang dyno bullshit.

That right there should be the end of this thread.

SHOW ME AN RB20 DYNO SHEET WHERE THE RB20 WITH NO SPRAY ON STOCK TURBO, STOCK HEAD, STOCK BLOCK MAKES OVER 300WHP AND I'LL STFU.

I mean you have 2 extra cyl. I'm sure ya'll can do it."

Mustang BS? I fail to see your short-sighted point. The Mustang dyno is more accurate than many out there because it actually takes into account the weight of the car and other factors. I probably cannot show you a dyno sheet where a stock RB20 makes over 300whp, mainly because that is PUSHING the stock turbo's efficiency, not to mention the stock injectors are only 270cc. I don't know about you, but I prefer my injectors not to be at 115% duty cycle. As far as your 2 extra cylinder nonsense, they are the same FREAKING displacement....so your point is null and void.

"Man id be very irritated to have bought a RB swap, spent $1g in upgrades and only push 250whp on a mustang dyno."

Gosh you're right...except that I've fixed the problems that plagued me of the lower numbers, and once it is swapped over, I should easily be over the 300hp mark. Please unless you have something substantial to contribute to this discussion, stay out of it.

Guys once again, no one has yet to bring anything to this thread that has actually proven any point regarding the RB20 as an "archaic" motor with "old" technology. I'm not trying to stir up the hornets nest, but other than everyone's experiences with OTHER ppl's motors and dyno sheets, this thread has turned into nothing more than a bunch of guys yelling at each other with idle threats and ridiculous insults. I figured most of you would try to jump my case, but that is just fine. Unless someone brings some actual automotive knowledge to this discussion, then this thread is nothing more than playground banter.
