i was thinking about trading my fully worked SR for a RB it has work consisting over 5k into it ( Fully rebuilt cometic head gasket and arp studs, redtop fully upgraded valve train can withstand 8100 rpm's all JUN tit. valve train parts and JUN 264 cams , greddy suction kit ,greddy pullys ,apexi power FC, power fc boost controller kit , fully rebuilt transmission short shifter . I'm thinking i'm not going to be producing enogh power to play with the big boys around here so I'm thinking should i trade my built SR for a rb whole swap motor set and driveshaft and mounts what do you guys think.

I would take the RB25/26 any day over sr...

however if it is straight up trade, without consulting with the prices, I am not so sure if that is such a good idea. If you sell the sr off and buy the RB, you might be able to get "more" back

by the way, your poll is a bit strange. Isn't trading the SR is the same as getting the RB?

$5k may seem like alot now. its peanuts when you're dealing with RB's. its going to cost you ALOT of money ON TOP of your trade to "play with the big boys". good luck though.

to be completely honest. i wish i would have stuck with my SR. sold it and bought an RB. i KNEW it was gonna be expensive to work the RB to "play with the big boys" yet i still sold my SR. it didnt fully hit me how expensive it is till i started ordering parts for RB. to play with the big boys with the SR. 4-5 hundred ponies in a 240 is enough to play trust me. dont make the same mistake i did. keep what you have. work off what you have.

i think the last place you wanna post this is in a forum full of RB owners(we're a little biased.....)lol....j/k. being an rb owner, i would definitely say stick to the SR if you don't wanna spend a bundle. im sure the SR can put out enough power to "hang with the big boys." if you're not happy with the power you've got, build it some more. Unless you're just looking for something new.

With all due respect, you'd be stupid as hell to sell your SR20 at this point.... Put that mofo in and haul some *** for us Nissan owners.

You passed the point of no return with your SR, keep it and have fun. You would have difficulty getting what you put into back out and then you would be back to square one, no engine.

Word, keep the SR. $5000 in the RB world gets you a stock motor and a few boltons i.e. FMIC and an intake manifold.

lets just say you have spent $5000-6000. In the rb world. That equals a motor set for an rb25det greddy im, new oil pump, water pump, maybe new internals.

For an rb26dett. Your done cause it's about 4500-5000 then you need the rb25det transmission. then your done.

This is what they mean by big boy money. You'll still the the same hp outta these setups. Now its more fun of driving for us and bragging rights. I would have had the same sr setup you have but i ended up getting a damn rb25det. Man i'd trade you in a heart beat simply because i'm a cheap bastard and i want the most hp for my money. If your cheap like me you wont be happy with the expensive accessories of an rb motor.

good luck bro!

by the way my stock rb25det has killed sr20det's with 300-350hp(so they tell me at the end of the race). It's my top end in 5th gear that gets em every time on the highway.

I've stomped a few SR's to but the time and money that he has put into this project, ... it'd be dumb not to put it in something and just sell it out right, then do a RBswap.

Keep the SR. You already have a full titanium valve train?! That had to be close to $1500 alone (after machine work).

I love how people keep referring to it as "big boy money". Cracks me up because it is so true. Look up some cost threads and see if you can still play because if anything goes wrong, you will pay out your ear. Take it from me, if anybody has had a bad swap experience I would be the person to tell them, it's not that bad...

Instead of swapping for an RB, I would put some kickass suspension components with wheels and tires etc.

thanks you guys are raw ,I'm gonna keep it . What do you guys think about my setup and i didnt spend 5k i get free labor. A friend goes to penco tech but with labor cost thats how much i would have been fully taken apart cleaned and new gaskets What would be ideal for turbo and injectors for they are the only things i have stock besides bottom end. i was thinking tomei exhuast mani. and a t2871R 84 a/r since the mani flows so well it should act like a 64 and maybe 740 or 555 nismo's . Looking for something for a very fast street car 100% of my funding from work goes to my car so money just takes time but dosent consern me once again thanks guys

The GT2871R is supposed to be good for 400hp.For 400hp your gonna need 710cc injectors, (if I did the calc right)Use this website to pick injectors:http://rceng.com/technical.htm

a built sr can reliably put down 500hp, see what you need to the rb20....?

His SR isn't built for 500 reliably though. But to each his own. If you decide not to put me in contact with the RB guy. I have a Redtop SR and the parts for 400whp.
