As you guy now my rx7 is high compression and its turbo

https://www.nopistons.com/forums/pub...1047683473.gif

well this past saturday i was driving home from work after i installed my rb downpipe ..when a greenish silver turbo nissan 240sx came up next to me.i could hear his blow valve.and i was so tempted . i revd at him and we raced ......well i simple can say that i killed him..and bad ...like 5cars...Actually he kept up next to me until the middle of 2rd gear ..i give him credit..it was cool ...then i notice that my car was right in the midle of lean ..... https://www.nopistons.com/forums/pub...1047683664.gif

what are your mods? can a stock high compression rotary motor handle 12psi?

Like B said what are your mods?Good kill try to get it on tape next time. https://www.nopistons.com/forums/pub...DIR#>/wink.png

Do you know what the 240 had done to it?

There are many swaps that can be done into a 240 (KA-t, SR, RB20, RB25, RB26), you will have to be a little more specific when laying down a story.



It was most likely a SR, since that is a common swap.

dude he said the guy came up next to him with a bov not much more description available most the time. id be willing to bet irs sr or jsut a kit on the KA not much more that would lose so horribly to a 7 even with highcompression and 12lbs...



aurosting u have hp numbers for ur car?

Well I keep myself updated with the cars around here. If I race someone I am willing to either talk to them after the race or find out from someone else what is done to the car.

For all we know it was a KA-t with a Sabb T3 junk yard turbo setup running 5psi.



That's why I ask.

He might not know, but then again he might....so it's not going to hurt to ask.

nice kill

I highly doubt that RB 240's are running around too frequently. Doesn't that swap require money out the ass like a 20B into the FD would?

there is a RB s13 for sale in my area, its not that expensive...

Not really......I have an S13 with an RB25DET ( cost me $3800 for everything). My friend has an RB26 in his S13 (has to many mods to list) and I have another friend that bought his RB25DET clip with mine and is doing the swap before spring. Then also another friend that plans on doing a RB26 in his S13 also.



So are they uncommon?, well not around here!

An SR20 is plenty and the cheapest to do. Out of the Rb's the 26 is the only one worth it. Plus the Rb weight more.

Your wrong.... I have researched and have worked on allot of these motors and know the potential of them all. The RB25 is a very good motor and has been taken up to 587HP on the stock motor (meaning nothing done to the head or block.) The guy that made that 587HP stoped right there becuase he knew that he would blow out the stock head gasket. This month he will be putting in a new 1.5mm+ metal head gasket and new ARP head studs and then is going to the dyno again. He is shooting for 650HP on the stock head and stock block. So when you say that the RB26 is the only one worth it, well that's just a unknowledgable statement. You need to research the motors before you speak out loud. Once you research the RB's you will find out that the RB25 and RB26 have allot of inerchangable parts. I could take the RB26 internals (pistons, rods, and crank) and swap them into my RB25. Almost everything can be swaped over. Soon I plan on throwing on the RB26 surge tank setup onto my RB25 and maybe keeping the individual throttle bodies or might make a flang with on the inlet and putting on a Q45 90mm throttle body since the intake and exhuast manifolds from the RB26 will bolt up.



The SR is a good motor, but you will not have anywhere near the potential you would with an inline 6. The SR has been taken up to 545HP on stock internals (bottom end) with a semi built block. Well the RB25 has already beat that with an untouched head or block. If you are looking for 450+HP with the least amount of money, well I would say go with the RB25 or RB26.



Zach

sorry....meant semi built head not block.

i dont really know what the guy had , but i know he had turbo...in addition i really dint thinkon pulling over and asking him what he had

here is a new complete run-down of my setup







1----non-ported 6 port 1987 n/a high comp engine "9.4 compression"(seals and gasket of a t2 for safty and yes it can be done)

2----t2 intake manifold

3----msd fuel pressure regulator with boost index

4----4 t2 550cc injectors

5---- t2 fuel pump

6----t04b turbo a/r 96 p-trim

7 ----took the stock back end of a t2 turbo housing and got it bored out so the t04 fits in perfecty and got the whole turbo ceramic coeted and i also get to use the stock waste gate

8----racing beat 3" down pipe

9----single 2.5 exhust with a 4" muffer

8----stock n/a trans

9----no power steering, a/c , and pollution pump

10----20w50 oil

11----ngk b9es spark plugs

12---- 4 puck bronz racing clutch

13----hks blow off valve

14----t2 hood

15----10 psi of boost

16----atkin one peice "wha u ma cal it"(dont remember its name)

17---- thats all i can remember off the top of my mind

That's a nice setup....congrats!



Do you know what you are making for power?

Have you taken it to the track?, if so what are your times?

i agree....rb has more potential, but it also does weight more

They actually wieghed an S13 with an RB25 in it and it wieghed 2780lbs. compared to the S13 SR that normally wieghs 2650lbs. So an extra 130lbs. isn't that much of a difference. A stock RB25 would easily win against a stock SR any day.

Do you have a pic of the port match t2 lim?

how do u get a stock high compression n/a 13b.

Nice kills...

did they have the same turbo, exhaust manifold, radiator, ic and ic piping?

did they also have all the same options? like pw,ps and ac? you can't put two different motors into two different cars and get a reliable weigth difference

Maybe I shouldn't regret getting an FC instead of getting another 240 after i crashed it

They where both S13 hatches with a full interior. They both had stock rims and a FMIC. Other than that they are both completely stock. So it is stock for stock pretty much. I have researched both swaps in detail and know the difference between them. This is a fact: "the wieght difference between a S13 RB25 and an S13 SR is around 130lbs.".

Hell yah.. Nice kill man... hey DETurbine.. you have AIM? I'd love to discuss the RB25 swap with you some more. I know a friend of mine in Houston is doing this to his S14 for his wife

TheAntiChrice- you have a PM!

what are you using for engine management?

yeah what are you running for engine man.?

i have the stock ecu for an n/a

det where did u and ur guys get ur clips from? id like to see ur swap, u got pics?

My friend with his RB26 got his from Japan. He went actually to Japan and bought it. I and my other friend got our RB25's from RacingHard.com and our other friends that are getting theirs next month, well they are getting theirs from our good friend in Japan.



I will try and get pictures up of mine and my friends car ASAP.

GD Nimrod in his FD with only 6 lbs of Boost smoked a 240 with an RB25 like nothin.... now that's a kill!

What is done to GD Nimrod car?



S13 with an RB25 runs mid 13's on stock suspension and about 11psi.

An RB25 S13 with coilovers, LSD, drag radials, and about 14psi will run a high 12.

Are you sure he had an RB25 rather than an RB20?





I have raced high 13 sec cars and have taken them by about 5 car lengths. My S13 RB25 is stock except the exhuast and test pipe....other than that I have nothing. I have extremely blown struts, bald all season cheap tires, one wheel wonder (no LSD), and 10psi and have taken high 13 sec cars. I have spent $4200 on my whole project.....that's including the car itself. I plan on running high 12's this summer once I get some Nitto's, R200 LSD, and JIC FLT-A1's. I don't think I will have a problem making it either, since it has been done before many times.

i emailed racing hard.com a few days ago and they said 2000 usd shipped for a clip with diff, and driveshaft. i feel a little leary ordering from them since they are in malaysia. but thats half the price of everyone else.

nice kill

FC's kick ass!!! nice kill https://www.nopistons.com/forums/pub...1047683894.gif

My brother drove an S14 with an SR, standard BPU's, and @ 14psi it ran 13 flat. Now he's driving with the same motor and same mods in an RPS13 and there's a HUGE difference in speed and stability overall. 10PSI on the fastback feels like 14psi did on the S14...it's awesome.



In my brother's car we waste C5's, WS6's, Lightning's, SS's, and all that junk. '03 Cobra's are nothing too.



So far the only car he's lost to is a modded Z06 that barely pulled in 3rd, and the Super-Charged V8 SL500 Mercedes, or whatever it's called...



btw, this is all on the stock turbo too! T-25. lol....

He's goin T-28 now. bigger injectors, and he'll be pushing 22psi...woot woot!
