RB20? ummm not me. if you clicked the link thats the CA18DET i was supposed to get from flashoptions. i wasnt tryin to knock anybody for getting the 20. i think its a really good motor, id get it over the sr20. all i was saying, is that the only reason someone would buy an RB20(except those few who want to build a motor to rev to 9 grand) ove rhte RB25, would be the cheap entry price. i dont blame anybody for going for it. look at me, i went with hte CA. its even cheaper than the rb20, has less TQ, and is a more rev happy motor.
I wasn't flaming you man. For some reason I was thinking that you were the guy w/ that R31 RB20. :pface

sorry man i wasn't flaming you . just i don't like it when people assume things;)and rev's yes. he got that answer from me. lol. and noob...hahahai did my first rb over a year ago...i'm no noob. but i guess you wouldn't have know that. the 20 is my choice for a few reasons. higher revs. i don't need alot of torque. and i don't need more tthan 350hp. i don't street race. i'm into YAW control. also know as drifting. plus it's seems like everyone has a 25 these days.and money doesn't matter. plus i didn't have to buy this clip that i have.i traded for it. but most of my rb info i have is for the 20's. granted the 25 has a whopping 30 more hp. and torque. i don't need torque i can do alot with out it. i've had a few hachi's. so drifting with out torque isn't a issue.and to boot my 20 was a AWD auto...lol...out of a gts-4 with 50,000 km's on it. i picked up the needed parts for once again favores and trades.i'm a drifter i'm not a trailer queen. not calling anyone a trailer queen or anything. just i don't want the babam check me out shiat. so is that good enuff?

and wait hold up.....so you call me a noob and your a honda kid?your just now doing your first swap a ca18det? i'm not picking a fight or anything. but it says a honda for now in your profile.if i am correct and this is the case then you have no rite what so ever to call me noob. i am on my 4th s13 2 sr's and 2 rb20's. and have been doing swaps for a living for over a year now. i take offense at being called a noob all because i just now actually made a screen name for the nico forum.i've not really had a need to goto a new forum but i got bored and figured one day i would get a SN.

well, i call you a noob because your post count is low. im a kinda well established member, and flaming me(and you were) is not cool. as for the honda thing, its been my daily driver for 4 years. also, im about to be on my third 240 in just over a year if thats any consolation. remember, you my not be a noob to nissans, but yoiu are a noob to this forum, so show a lil respect.

so six months on a forum and your a well respected member. also 3 240's in a year. sounds like alot of incomplete projects.also answer me this. why a ca18? had to be cause of the money. the sr has more hp and torque. so it has to be cause of the money. i meen i just don't see why?does that sound familiar? and no i'm not a ca hater. actually i'm a sr hater but the point is people do things for a reason alot of times.i will show respect were respect is do.ok. and i was flaming a flamer.(and you were flaming) i like to take up for people on the net. and i am no noob to nico. i've been reading nico for a while. just never felt the need to make a name. so just think before you jump on someone ok. here i was thinking you had a rb25 in your car and was giving someone advice but it turns out you don't.also i would like to say sorry for anyone who thinks i'm being offensive to someone. i am willing to drop it now.if you feel the need to yell at me some more please do it in PM's.i dont want a public war please. like i said i was just taking up for someone.

i was not flaming him. i was simply saying that if your not going to be able to do/complete a project the right way then dont do it.(as in dont do it half assed). im sorry if I offended anyone, i meant no harm. about the sr20, well i dont too much care for it. i dont like timing chains or the design of the valvetrain, other than that i love the sr. before i bought the ca, my chioces were between the rb25 and the ca18. and yes your right, the 25 was a bit out of reach for me at the time, but at least i can get parts for the ca anywhere. anyway, i would appreciate it if you could be a little more polite. thanks!

I was reading through this and a couple things got my attention. Low post count and registraton date does not =noob. I also thought it seemed like everyone had a 25 these days. But havent seen much proof. Yes drifting can be done on low TQ but its also nice to have it. Yes everyone should build their car for what they want and can afford. what I dont agree with is "just i don't want the babam check me out shiat" I dont think everyone with the 25 is like that.

Can you see that check me out shiat here

And thats my daily driver. I am in no way trying starting a fued but not everyone has that look what I got mentality. Although I did for a week or two. But nobody is perfect.

Killa don't even consider building any of those motors NA. That would be the stupidest thing I've ver heard of if you imported one of them ... strpped the turbo and rebuilt it for NA... just use your KA they are good engines too you know....

ya I know there are.... but wtf would be the point. An NA KA and an NA SR aren't all that different from eachother as far as power ( Sr revs, KA torques I know) so why spend the money to put in the SR when the KA is a GOOD ENGINE. Plus. Are there any NA SR's that even came in rear wheel drive? most people that mess with the NA SR's do it in a Pulsar.

hmm jus thot of it...u hav 2 consider the fact that ive been working on na motors most of my life and well this turbo thing isnt really gettin to me much. but still though, my lifelong dream would be to have a 12 second na powered car. mustangs do come close enuff but too much gas needed. so well newayz, anyone here know how much horsepower the rb20, rb25, or rb26 have in NA form? i would ask nightxcz77 but i havnt seen him online for a long long time

they did make a rb26de...i think it was like 200hp maybe not sure i would need some time on google to find out. a freind of mine was thinking of doing that swap till he found out there was only i think about 1000 or so motors made...something to that effect..don't quote me tho...they did make a rb25de motor for the r32's i've looked at it in my r32 FSM...well it's a freind of mines manual.

ok lets see here specs for rb20de from the book.disp=1998bore x stroke 78. x 69.7comp ratio=10.2comp pressure=13.0kg/cm @300rpmmax output(net)ps/rpm=155/6400max torque(net)(kg-m/rpm)18.8/5200

and the rb25dedisp=2498bore x stroke 86.0x71.7comp ratio=10.0comp pressure=12.8@300rpmmax output(net)ps/rpm=180/6000max torque(net)(kg-m/rpm)23.0/5200

and this is all r32...NA not turbo...

and please don't ask me to post wiring info....i'm not in a position to do it please understand.

why don't you look at the sr16/sr20ve's? those things are n/a, sound a whole lot like a vtec motor, but pisses all over the B18C from honda.

As far as i know, those things had a limited run production and are hard to find. I think the newer premiera's from japan had them. they're all FWD as far as i know.

I'm not saying the motors weren't made... or that they aren't fast... but come on people... what a BLATANT waste of money??? fine so some silvias and 180sx came NA... poor guy still has to buy an engine from Japan which is never that cheap, then build it to a sickening level to get that 12 second car.... even if he hated turbos or knew nothing about them... he could probably just have a shop put a turbo on his KA or import one of the turbo motors, do things such a larger turbo, injectors, fuel management, exhaust, hell buying an RB25 and having McKinney install it would probably cost less in the long run and get him that 12 second car... and he still wouldn't have to know a thing about turbos

yeah but still. i mean the satisfaction of knowing u do sumthing urself is much greater than simply having sumthing done for u. id be a lot happier building a na motor by myself even a ka24de that rns a 13 second quarter mile rather than just spending money and having someone building a 10 second car for me. i mean i hang around my cousins a lot and three of them built their own motors. they give carlengths to camaro ss and stock mustang cobras but they do get handed by corvette zo6's once a while. well u get the point.

Speed cost money.

All motor speed cost more

Turbo speed cost less

How fast can you afford to go ?

Well Killa whatever you choose to do I wish you luck, in my own opinion you really need to either go with a larger motor if your going to go N/A, or just go turbo! But thats just me, Let us know how your N/A project turns out
