My first Rb'd 240!!!!!! Advice?

[kamikazeee]

Alright so I finally got my 240!!! My third one now, 1991 Coupe with a rb20det 95k on the body, 65 on the engine (got papers :P) not a specccccc of rust (can't say that about my last two). Not big into coupes but I gotta pretty good deal on it, gotta do a few things to it (tachometer, speedo and some other things). Only one picture for today sadly, but I'll get more.

Its pretty much a stocker.

I don't wanna do much to it right now but engine wise what do you start with on an rb? Its got an oil cooler, a radiator and fans aftermarket everything else is stock. I read up on these and most people would say bigger turbo (prolly right ) but I don't know we'll see I haven't pushed it yet, gotta get it onto a lift first. I really gotta get a new bov, i was thinking ssqv but everyones got one, the stock one is actually loud which is surprising? Maybe Rfl turbo xs, well I don't know. Lemme know what ya think should be my first step and I will go begin de-ricing the ride. Thanks!

hmmm... clutch be slippin.... damnnnnn....

Asking what blow off valve you should buy to de-rice the car is hilarious.

You should probably replace that clutch.

[kamikazeee]

haha, the stocker is like ridiculously weird sounding

and yea that is the first thing now sadly.... than tach from ls-auto

[Metal Angel]

I hear these rev to 8 or 9 k easy. start by making a 9k head is my vote. that way you can keep up with all the honda k swaps tooling around these days.

Transmissions

[kamikazeee]

This one redlines at about 6500-7500 from what I can tell, but it would be pretty awesome if I could go higher, car has zero pull below 4k or so. haha but i really don't care bout the hondas, not too many around, just damn camaros t-birds and mustangs.... sadly I don't think I'll be beating those anytime soon

I had a built up trans before but i really had no need for it, so ima stick with this trans unless I wanna go higher power, all i really want is bout 250 to the wheels and I am done. I have no clue what it is now, I'm dynoying it at my school thursday so we'll see i guess.

All in all I'm pretty happy with the rb, seems pretty good to me, gas milage is not too bad, its got some pull to it and it slides, all that matters.

Got some crazy bug lights up front (dual pod) and a vented hood with hoodpins (that really scare me on the highway) and the vented aerodynamic fenders haha.

Anyone happen to be looking for any of those? sell em real cheap. Oh and a pilot steering wheel with the 2 nos horn buttons and square bottom

[Armstec_S13]

Advice, don't crash it and don't drive it in the snow, what part of tinley?

[kamikazeee]

My only ride i'm gunna have to drive it in snow, I'm pretty used to the snow tho, i don't try to be dumb. Just gotta rubberize the s*** out of the bottom, rails and s***. like by the train station in tinley?

[93sivliaUsdm]

Well you would greatly benefit from a proper dyno tune, test pipe(if it doesnt have one already), injectors, fuel pump, and new turbo manifold and turbo if your really looking for more power

[CA18Magic]

haha, the stocker is like ridiculously weird sounding

and yea that is the first thing now sadly.... than tach from ls-auto

If you are hearing the "fluttery hooting" sound... and you think it sounds ridiculous... i will hunt you down, pull you're motor... and drop in a honda zc in there. I love the stock bov sound!

[kamikazeee]

haha please don't hunt me down

and I'm putting it on a dyno thursday, maybe I can take it somewhere to tune it soon too. Ya I think Gtr injectors and turbo sounds good, I seen some people do that.

[safin]

for now post more pics

[kamikazeee]

haha aight ima go out take pictures now...

[spolitte]

alluminum radiator is a good call. Also, if you are gonna upgrade turbos, definately get better fuel system (i.e. injectors, pump, and fpr) as others have mentioned, also will probably want a FMIC as opposed to the side mount since the compressed air is gonna get a lot hotter with more psi. Finally, since it is the 2.0 liter it'll rev to 8k all day no problem. With just cams and not even springs or anything it'll push 8.5k rpms. But definately should be revving more than just 6.5-7.5 stocker. I thought 7-7.5 is what a rb25 and rb26 should hit stock?

And yes, get off your couch and get some more pics posted asap.

[kamikazeee]

Just bought a koyo today, just gotta put it in, it came with a fmic, not too big but seems adequate, and yea i was thinkin walboro fuel pump out of my other 240, throw some gtr injectors, fuel rail (no clue what kind can't find any) gtr turbo, and dyno n tune it, thats my plan for now we'll see. Also I was looking at bigger intake manifolds but I think the one thats on isn't too bad.

And I was assuming it revvs at 6.5 7.5 I don't know I can't calibrate my tach for the life of me like everyone said, you gotta be perfectly on, so I ordered the ls-auto one.

One other thing that worries me is that when I turn the key to the on position it lights up all the lights except oil pressure, changed the bulb still nothing. Is that normal?

Is there any thing like a oil cooler thermostat? My car seems to take a really long time to warm up, I mean it stays warm and all but just from start it takes so long... Maybe its normal I don't really know rb's too well.

And i took some pics ya can't see s*** tho, so tomorro morning

[spolitte]

Maybe the oil pressure sending unit isn't wired up with the swap? Not sure however, as my oil pressure lite on the dash doesn't work either (i need to look into auto meter one or something), but no help from me unfortunately other than yes they have after market oil and water temp gauges, as well as oil pressure gauges. As for taking a long time to warm up, the only experience I have with RB's is my own so don't just go by what I say, but it warms up in about average time for such a small engine, and mine has tended to overheat a bit depending on ambient temps and my how I am pushing the engine, but gotta love iron blocks as they are a bit more giving on temperature over alluminum ones. Also, my dual FaL fans dont have a great setup, just a jury rigged trigger that senses the outside temp of the radiator (needs fixing asap, and will probably run it through the AEM when I get a chance for some dyno time and tuning).

Other than that, gl with the 240rb as they are awesomely fun cars, and have such sweet exhaust notes, especially when its screamin like a formula car at high rpms.

[kamikazeee]

Yea thats what im hoping for, prolly just gunna get an oil pressure gauge with a light.... And i meant like a thermostat for the oil cooler to stop flow trough the oil cooler so it warms up a little faster.

But yea I got some crazy fans on mine, its winter so it doesn't overheat yet and hopefully won't ever haha.

And the redlining sound of the rb is like the sickest sound ever, some tokyo drift s*** yo haha like seriously i love it

Thanks tho, I'm hoping everything will go as planned

[spolitte]

eesh, i dont know about a thermo's for your oil cooler. You always want oil running through your system, and definately dont want oil being blocked in any way.

Maybe you mean a bypass valve sort of deal so if the oil is x degrees it doesnt go through your oil cooler? but even then i'd say bad idea. Just put some lighter weight oil in the car during the winter months. I think i have 5w-30 in right now or something of that sort, and will go back to 10w-40 during the summer for rough and hot driving.

Anyways, oil temp doesnt have nearly as much to do with the engine blocks temp as does coolent, so if that is your problem then run a 50/50 mixture of coolant with reg thermostat during the winter, and if you need to, run a low temp thermostat with more water and less coolent (but leave some coolent in for lube and anti-rust) during the summer.

However, the fact that your engine takes a while to warm up is not out of the ordinary. While gasoline engines perform optimally at a temp of about 195 F, running them cold isn't too much of a concern, so long as you don't beat the crap out of the engine if it is about -20 outside and you just turned on the car. I'd be more concerned about the turbo at that point than the block itself to be honest (which is why I am thinking about putting a remote starter in my car).

I would regulary start my car and let it run for 5-10 mins before going to school back in high school and the temp sensor still wouldnt even register at 100 F, but then again it was a 4.3L chevy, which will take more time to warm up just because of the size

hey man nice car,look forward to seeing more pics.in new zealand we have alot of rb,s,some good first mods would be to do a front facing plenum to shorten your piping down and gaining response and that shud help hit boost alil sooner to.even add a boost tap,you can run 1.bar safely all day everyday,and while your doing your clutch get a lightened or chromoly flywheel.as for running your car up to 8 or 9k rpm,i personlly dont see the point coz it peaks at like 6.5 and red lines at 7.not unless you have a real serious motor and computer to push it to those limits(my opinion)

I think you would notice a huge difference with just those mods,but if you wanted more i would then get a bigger throttle body and gtr injectors(444cc) or even rb25(370cc) injecters,it all about the flow.then a chip or computer,extrctors.the bolt ons are endless.

thts just my opinion anyway,goodluck with your new toy

[bllabong89]

did u get that thing off craigslist in the stl area. i saw a s13 with an rb20 that looked just like that on there for a few weeks now. i was gonna try and trade my bike for it. i hope you enjoy

[vda240]

Yep I test drove this thing about 2 months ago... The bosnian guy was asking 3500 for it. Clutch was slipping, suspension is shot, front end looks gay (no offense) other than that its a nice car with alittle bit of work it will be very nice. He also showed me pictures when he took the valve cover off and it looked super clean under there! Anyway enjoy the car man!

[kamikazeee]

eesh, i dont know about a thermo's for your oil cooler. You always want oil runnin....

Yea, i found that bypass thing online, haha after what you said I realize that its a bad idea, i got 5w-30 in it right now, and I need to change out the coolant thats it, I think I'm just not used to warming up cars, cause my ka wormed up in like seconds really haha? I don't know I always warm up my car untill it just goes past cold, still don't beat it until its in the middle. haha so its all good. I'll get used to it and check everything out to make sure its running good.

Haha ya v8 would def warm up a lil longer than my lil 2.0 i6 haha

hey man nice car,look forward to seeing more pics.in new zealand we have alot of rb,s,some goo....

I wanted to get a front facing plenum, but they lil expensive, not bout to spend a grand haha, maybe i can fab something up, that;d be sweet haha. Right now the cqr is on 8psi (.55 bar i think?), so doubling that would be cool, and yea i'm def not changing the clutch till after winter haha, but yea i want a light one (do all of them vibrate at high rpms? I had a fidanza and if i hit over 5k it would vibrate my whole center counsel ).

But yes def gettin a bigger tb and headers for sure! Those rb25 injectors sound really good to me! I think I've decided on them now, what size are rb20 injectors?

But yes I will have alotta fun hopefully! Thanks!

Haha thats the one! and yea i think it was a good buy!

Yea haha i lowered him a lil and yes clutch is slippin like crazy, he gave me an extra one tho, (still prolly gunna get something else, recommendations?), and shocks but i got some tien shocks and kyb adj, funny thing is the front left and the rear right shock is blown so the car bounces in a really funny way hah. And i got a pignose instead of the invader! haha Yea i lost those pics but i'm planning to take a peak too, it looked super clean. But yea thanks alot man! It needs some work but should be getting there soon. Suspension lights and fenders tomorro morning!

Well they're phone pics, i need a camera charger....

But enjoy!!!! ahhaha



Damn how do you make them smaller!?

make what smaller?

[vda240]

make what smaller?

Haha probably pics...

I'm not an expert on RB's but a guy I know with RB20 hatch has a Spec stage 1 and it held up great so far (so he says ) Anyway, all I can reccomend you man is this website, great selection of RB parts.

http://shop.rawbrokerage.com/main.sc

Keep us updates on the progress, I'm curious to see it transform.

[kamikazeee]

WOWW!!!! Thanks man, that is an awesome website!!!! Bout to order the spec clutch or the act clutch.

And yea I got it lil lowered today, put the shocks and springs on, than brakes, just some ebay brembos from my other car, but it'll do for now. Changing those hideous lights tomorrow, and the fenders. Painting it on saturday.

Found a lil oil leak from the dump line today, and an antifreeze leak god knows where, can't find it for the life of me.

Thanks

you dont need to spend 1k on a front facing plenum.we get them here for 300 but...its not ideal but it does work,what you can do is just take your original plenum to a fabricater and get them to weld up the existing hole then get them to cut a hole in the front of your plenum and weld the old bracket on to bolt your throttle body on to.then just get your throttle cable extended to suit.i dont think it shoud cost more than $300 all up.im pretty sure the rb20 injectors are 270cc.the only issue with the rb25det injectors (which slipt my mind completely)is that they are side feed so no gud for the 20det.so you might wana go the 444cc gtr ones.altho i run mitsubishi evo 3 injectors which are 510cc which is a awesome upgrade,i run 300kw at the wheels in mine but with those i could go up to roughly 550-600hp,so i guess you have to decide what sort of power you want before you upgrade lol.i really do recommend doing your flywheel when you do your clutch.because the response and acceleration you will gain will be totally worth it

[kamikazeee]

Oh wow, that doesn't sound too bad, i actually no a pretty good fab guy that can do it cheap, didn't think abut that. And yea i saw them online i was like damn...... All i really want is somewhere within the range of 250-300hp, Thats why i was thinkin lil bigger turbo the plenum, gtr injectors, wlboro, and a tune and i should be good. I noticed i gotta get a different exhause this one is so restrictive its 2.0 piping in some places, think it was like welded together.

[kamikazeee]

very bad in snow as i assumed.....
