probably 600's

That would be my guess, looking for exact #'s

mr_eh

but I have a 35r and drive it on the street with 30psi it's totally streetable!

I wouldn't call it a fun streetable turbo...

Perfectly streetable low rpms save gas high rpms rape victims with a smile of course

Everybody I knew who had a GTS-T R32 or C33 or A31 all had one thing to say about their RB20...I cant wait for this POS to blow so I can go RB25. Why do I say RB20s are throwaway engines? Because people would rather swap in lighter SR20s than keep them in their cars, plus you get the added advantage of less weight. RB20s start hitting their limit around the same point as the SR20 for the most part. Both engines seems to hit their limit around 450hp, after that, you're on your own.

To be honest, I don't really see what all the fuss is about. My rb20 is nothing like people say. It isn't a gutless fish. It Drives just fine out of boost, It's not like some Geo Metro that is straining to get to highway speeds.
I can cruise around no problem.

and To say the Rb20 is torqueless.. wrong. ( maybe on stock setup yes ) but throw a decent sized turbo on it and it smacks me back in my seat every time.
Spool up is slow.. it doesn't have an instant boost button. never will. When you floor it, you're not going to really get that hard acceleration until full boost. but what turbo car does anyway.

I'll say this. If you are planning to get an Rb20, do yourself a favor and buy a real turbo for it or you wont have fun.
Not a Rb20 turbo
Not a Rb25 turbo
Not a t25/28 turbo
a REAL turbo Gt30R at the SMALLEST.
it's not a slow gutless engine, it just needs ALOOT of boost!


it's really not a bad engine for the price imo. plus it's a fun swap, easy swap, and it sounds nice because it isn't loud even with 3'' straight pipe. just sounds smooth. no BWAAAAA no ricer sounds. just a really smooth sound.

but if you aren't going to invest in a turbo and supporting mods to make it fun, just get a RB25 or Sr20.

I'd call it a lot of fun... it's a twin scroll setup, spools early.

you kind of sound like a majoooooooooor fan boy of the rb20. A little bit over the top...

In the defense of the RB20, that motor came in bigger cars so of course people with bigger cars may dislike the rb20 more so than if it came in a smaller car. The engine is heavy but it's still a fairly good engine. It's just hard to justify 6 cylinder 2 liter with little aftermarket support when the SR20 and rb25 is so readily available.

OrangeVirus1

My turbo is twin scroll and flows like a 35R.. and does not spool that fast...

I was never originally a rb20 fan boy.. Zilvia turned me into one with all the hate. I'm going to love it and defend it solely to piss you people off.


Not even going to bother. how about reading page 1 dude.

NVM Dude.. Saw your build thread.. GLWT RB2DET..

lol i love these threads. my vote is 2jz because it will handle 450+ with oem internals and its cheaper than the RB to install and tune and modify. No contest.
displacement always wins. Sorry 2.0 is nothing. 2.5 is also nothing. 3.0 is just barely cutting it.

have any dyno sheets? i cant imagine something smaller than a 35r that doesnt spool fast and is twin scroll? maybe poor intake manifold?

it's probably because my hotside AR is 1.00 twin scroll, and my engine is 2.0. Stock RB20 intake manifold. Everywhere I have read online says the stock RB20 intake manifold flows really well.

mr_eh

i'm using a 1.06 housing... flows just dandy, maybe it's just the engine characteristics that are making the turbos spool differently ... which is why SR20 > RB20 ALL DAY (i'm kidding)

what RPM do you get full boost? I get 28psi at around 5200 rpm, but don't even see 5psi until 4k rpm.

mr_eh

looks like at 4k im at 12-13 psi. 30 at 6250

Looks like you are quicker to get boost, but I'm quicker to get full spool, even though I'm topping at 28, not 30.
at 6k rpm I'm well into boost by then. the kick is awesome too. Do you get that in your car? like floor it, spoolin...spooling.. boost hits.. full boost and kicks you back like hell.

I'm going to be dyno-ing probably next weekend. Waiting on my new tires, suspension and other misc stuff in the mail.

mr_eh

it's honestly so god damn linear it never feels like it hits hard... it's just a gradual pull, not violent at all, you notice the mph ramp up more than anything...

which is pretty good for a car that is rwd, that sudden burst of power doesnt make life easier

ahh.. my car is the total opposite lol!

my car is like this : low Rpm.. floor it... Car pretends it's cruising.. turbo spools.. still cruising.. turbo spooled.. BAM power unleashed.

I love it though.. the kick is awesome.

like this video of mine , nothing happens until full spool :
http://www.youtube.com/watch?v=L1q_ug0ppJs
not the best example.. but it's all I got.

Just because you have a split ex housing doesn't mean you have a twin scroll setup. Your manifold dictates that and I've seen the manifold you're running, it is not a TS.

no my manifold isn't. and I wasn't awared of that actually, Thought Twin scroll had to do with the turbo hotside housing.

I could be wrong on some of this so...[/QUOTE]

I'm not all about dropping a loafing V8 in an import, but I have to disagree on a few things on this one

With the right gearing (really tall T-56 or T6060), you can easily get 25-26mpg, maybe more. A lot of the SR guys average that or worse. I get about 29mpg sometimes 30, and I've been told I'm doing really good for an SR20.

I think if you shop around, you can do the swap for not much more than an upgraded SR20det swap. Figure

LS1/LS2 can be had for cheap. I got my L92/6.2 with ECU, wire harness, pedal assembly and all accessories for $2,800 for my SL-C project. You can get a T56 for around a grand used. The rest is fabrication, fabrication.

I've got a little less than $4.5k in my SR Swap (and that's being very frugal), with upgraded ECU, 550cc, FMIC, Z32 MAF, GT2860rs (about to upgrade to gtx2867), drive-shaft (mine was an auto), full exhaust. Stage 4 clutch, yadda yadda, yes there are a few other things I didn't need (ACT Chromoly flywheel), but figure for about $6K you could probably do an LS swap (haven't looked up, just guessing here).

jr_ss

Although having a split housing is half of it, the manifold has to have certain cylinders paired together with a split/divided collector and a pair of wastegates to purge the excess exhaust gases from each side.

So essentially, youre half way there. You have two options, do away with that waste of an exhaust housing and get something smaller and less laggier, or throw the RB20 in the trash and upgrade to an RB25...

I'm just kidding, however, good luck finding a TS manifold for your engine.

And seriously, chill out with your RB20 hard on. No one really cares, and you aren't going to change anyone's mind here or in Japan that the RB20 is garbage by jerking off to it on the web.

One of the very first replies to this thread said it all- You're 32 yrs old- Do your research and make a choice. Save making threads like this for the kiddos.

Second of all, unless something changed in the last couple days; you don't even have a car yet... "I'm gonna" says nothing. "I have" carries a little more weight. Coming from the Hon-duh scene; you should already know this.

Go to some events, ask some questions, do some Google searches etc. I bet there are thousands resources that cover 'which engine to get' for a 240 without having to rob the rest of us of IQ points.

Whatever you decide to do... all that matters is that you enjoy doing it and learn as much as you can.

No, no, no. Let's just hold lil timmy's 32 yo old Honda hand and let's guide him to the ZOMG best motor out there. And while we are at it, let's pick the parts that he will buy. Tell him which part to install first, second, third, etc.....

Why stop there. Let's also tell him when to take a shower, which shoes to buy, choose what to eat for him....


I mean really?

mr_eh

ayup



having a split housing on the turbo doesn't do anything without the manifold...
