building a 700hp+ RB25DET

Post by **gismonismo** » Wed Oct 08, 2008 6:04 am

Man such nice words there brother,He is right there almost balanced from fab.there only problem I have seen sow far is stiffness,There chasis need alot of work.I think some confuses the chasis stiffness with weight distribution.They have poor handling because of that ,So I think is the chasis that should be address and then weight dis.By the way I went today to see how my block is doing and he told me his having some problems with the torque specs.....??????Had to call ricky and ask him wtf if that?lol.I know torque specs come in the arp box since iI'm using aftermarket parts so I dont care about stock torque or whatevr they call it here.Thanks Ricky RB.now I know what you guys mean by language.lol.All I told him is please have it done by frday bro.lol.He also has my head since MMF didnt do sht to it,but he told me he will try to have it done by that time.

Who's "cheap @s 2jz build" are you talking about?

I just want to know more about the parts involved in your build...

yea those are also ebay units im seeing...to be honest with you with those intake manifold you have to be lucki enough to get one from a good batch i had one and it wasnt level on the block cuasing all sorts of leaks...i exchanged i for another one and i have no complaints so far from that.....that fuel rail tho i didnt like it felt way to cheap and leaked when i realy pushed the car....i stock with OEM fuel rail degreesed it and spray painted it and it works perfect and looks good at the same time

Post by **gismonismo** » Mon Oct 13, 2008 1:40 pm

well dont take offense to it man.lol.I just love fcking around.and no theres no point telling you sorry.You are on the dyno queen waiting line.I think you will be the first to get served.lol.gismo is my dog not gismon.lol

ebay costs more then it cost you to buy from a speed shop.I go there when I cant find a part,Its a cross your fingers thing if you don't buy proven parts,lots of hongkong sht.You guys should be care full there on ebay.lol.

Arent you building a RB25?? Why Didnt you go Greddy for the intake....

Post by **Ls1pwr** » Mon Oct 13, 2008 4:41 pm

dude your such a tool its not even funny. rcabrita tried to help u earlier by telling people to leave u alone and give you a chance to "prove us wrong". i cant believe u would treat someone like that after they helped u, and for your information the 2jz is farr superior to ur piece of $hit RB25 (with EBAY parts lol!). Do you wanna know why there are barely any parts for that engine??? CAUSE ITS A PIECE OF $HIT. Man the more u talk the more i doubt you will even break 500rwhp..... and even if you do it will be a "dyno queen"

Post by **gismonismo** » Mon Oct 13, 2008 5:41 pm

dude have you seen his ride?If I was into easy builds I would have gone with a 2jz.He doesn't need someone to defend him.lol.his car will kick your ls1 anytime man.lol.So whats your fcking point here?You already in so far theres no turning back man.You better come or select a place to race me or you will be the laughing stock in here man.

Post by **sjbsuperman1425** » Mon Oct 13, 2008 6:25 pm

yea you could have spent the money on a Gredy Intake mani and MADE of fuel rail if anything IMO. if you are shooting for high horsepower, you usually wouldn't want to funk around with ebay. im going to have to side wit ls1pwr on this one. Build it right or not at all man.

on the contrary(sp?) to ls1pwr though, there are plenty enough parts for the RB25DET so dont listen to that lol

Post by **S13_love** » Mon Oct 13, 2008 6:42 pm

Cool build. I hope that i'll get an rb25 one day.

Um..........I dont doubt you on your goal of reaching 750 hp (or whatever it was) but for torque...maybe at best expect around 500-550 for an rb25. 700+ is a little far fetched, even if you somehow were able to reach that, i would bet that you would crash pretty quick once you are driving it.

Post by **Ls1pwr** » Mon Oct 13, 2008 6:51 pm

theres no turning back?? listen little kid this is not the fast and the furious, im a grown man and i dont have time to go race u and ur little rb25. Toretto needs your car for Race Wars man u better hurry up and finish it!!!

so far i dont see anyone laughing at me, because im not the one coming on here and shouting out fairytale numbers like you......... 700rwtq my a$$

I don't have a 2JZ anything.And 2JZ swaps aren't easy.

I know a RB and SR swaps are easy. They have been around much longer and the kinks have been worked out.2JZ swaps are becoming more common but they definitly aren't easy.A 240SX (2JZ) vs 240SX (LS1) would come down to driver and what type of driving.

Also I appologize about before.I noticed you Fuel rail is SARD. SARD is a great company I just hope its real.When I said:

I wasn't being an as*hole. I was just asking because I was curious, not because I was being mean.

apparently you haven't either ! a 2jz and an ls1 are both 2x harder then an rb swap. you have to custom fab all the intercooler, exhaust, intake tubing for the 2jz. They have kits for the rb swaps for all of that because its much more common.

Post by **gismonismo** » Tue Oct 14, 2008 7:15 am

you mean that the red 240sx with huge rims ain't yours cabrita?Oh boy I did fck up didn't I?my bad dog................dude I don't know what to say...........sorry?.lol.God can't read and can't wright.I'm fcked up ain't I?.lol.sht......So what kind of car you have cabra?man my bad.Its ls1 fault...why you!

Got my crank collar today so its off to the machine shop yehaaaaa finally,god bless america and your take one month to get here japan sht.lol.friday my man john is giving me back my engine.Oh yeah ls1 its on man.As soon as I get my break in I'm hunting you man.lol................and tune it.. sht!and recabrita my bad dog.keep it up man,it was just a bad joke.lol.bad moyo,bad.pics to come.

heres a pic of the collar and cylinder oil drainer fitting I was telling you guys about.My girl picked up the jun collar So later I'll take a pic of both see If theres any diference.This is a kit he sells.I need to drain the oil from the head since the conversion don't need that much oil,The problem is not to much oil getting to the cylinder head.It's no being able to to match the flow when draining it to the sump.Thats when this comes to work.

Man you judging to far a head.For what I understand you guys think of it as a payless for shoes and rather go to Italian brands.It's cool.But ebay is not for those who goes for everything they see,My friend Chiba for example.He finds the hottest japan parts That you won't find here.yes there used but he hasn't sold me a crapy part,Take my turbo for example,its capable of 1000hp brand new.They sell it here for 2k to 3k.he got it for me at1,200usd.how don't know and don't care to find out.My mines tuned ecu was from him,plug it in and of I went.The thing is this .you can't buy from every one that shows you a good price.like when you go to the speed shop and the sell you a FPR turns out its defective.You probably won't buy from them anymore as long as you get your money back, right?I haven't went all ebay on this proyect put I think theres some parts you don't need to get them brand new.Like TB,short shiffter ect.I already know where to get my parts and from who.I'll post when this proyect is done how to get it and where I get it from.Cause if I tell you know when I have nothing to back up my build you will probably say what a marron or some sht.And yeah I think gt turbos are for auto transmission.t04s had given me way lots of fun.

Yea I know exactly which one you are talking about. I posted pictures on DSMRyan's (owner of the 2JZ-S14) thread but he emailed me those pictures so I just posted them for him.

A very slow, stock, and Champagne 1995 240SX.Just check out my signiture for picks and mods

Sick stuff Gismon!I am liking the setup so far!

I agree that Ebay is a great place to get certain parts. I don't think getting a TB from ebay is dumb. Its fine, but a ebay intake manifold is a little more dangerous then a short shifter...

Keep up the build Gismon!It is looking good

Thanks man.Heres some of the pics or the oil restrainers the silver one is the Tomei the other one (gold)colored is from my friendand these pics are from the crank collar the one in the left is the Jun I haven't messure them yet but they look the same diameterthe jun collar cost me 185.00usdmy freinds one cost me 90.00usdI'm sure your wondering about how well will it perform?well will see about that.Tomorrow I'm taking the crank to be micro polish,balanced and install the collar.I'll use my freinds one to see whats up.Plus install the drainer in the cylinder head.later

got a question if I have a spare rb25det with transmission and I want to put it in a s13 can I use one of my custom differential from my s14? will it fit?

Na no need to swap diffs. Just make sure you measure from transmission to diff and send those measurements to a DS company so you can get a custom lenth DS

All you need to do is Just use the S13 diffrential.S13 and S14 diffs are the same (R200 diffs).Some R200s are diffrent in lenth. Some of the R200s were put in cars with ABS and some with out. Since the sensor is located in the diff housing, it was nessisary to increase the lenth.

But every R200 is the same in terms of what type of diff can go in.

S15 Silvia = HLSD (3.6 FD)S14 240sx = OLSD (4.08 FD)S14 240sx = VLSD (4.08 FD)Infiniti J30 = VLSD All those options fit in the R200 so you can fit them into your S13 differential. Some of them use diffrent final drives, but the differential is the same. My car is a S14 w/o ABS and I am useing a S15 HLSD with my stock final drive of 4.08

Hope that helps!

ups my bad I mean drive shaft I have 2 custom drive shaft for s14.Can i use it on the s13 with the rb25det swap?There selling me a s13 coupe I think its a 89 for cheap and since I got a spare rb25 laying around.

Accually I am not sure.

I would mark how far your engine mount locations on your Cross member are from your differential on your S14Then do the same thing for the S13.

If the lenths are the same, then yea you could use the custom S14 driveshafts.

Post by **gismonismo** » Tue Oct 14, 2008 5:41 pm

I have right now 1 drive shaft shop and one from driveline service of atlanta.there both good ones.but I don't think I'm going all out on the s13 if i do buy it.let me know man and thanks man.

Heres another one.I went to solid lifters.I was planing on using a rb26 PFC D-jetro to change maf to map put: I was thinking If rb26 PFC is for non vct same as the rb20.Is there options on rb20s for e management?I know you can lose vct just by using a rb20 ECU on a rb25det.So if there is a EMS system out there for the rb20.Would it be better to go for an rb20?I don't know nothing about rb20s.Do rb20s use map or maf.I'm thinking the use maf since some say switching rb25 and rb20 ecu its like plug and play and its only for losing the vct on a rb25det, right?
