building a 700hp+ RB25DET

[gismonismo]

ok guys need some help on building the bottom end of my rb25det engineright now the head its getting some godies and aport &polish work,im working on the fuel system,and getting the greddy oil pump installedgoal is 675pounds of torquetalking about pistons (forged cooling channels)ruds(forged high bm)crank(balanced & knife edge)I'm thinking this will hold up to 800hp with out 2.8 stoker kit

itll be runing a gt37r 850cc injectors,aem wide band,power FC comander ecu.the rest no need to tell.lol.

You want to make 675wtorque with a gt37r? You better rethink your power goals and your setup. It isn't even physically possible for that turbo to flow that much air.

[Ls1pwr]

you sound like you wouldnt even know what to do with 675+ftlbs torque. honestly your goal will never be reached because its not realistic at all, not with the rb25 at least. now 675rwhp and around 450-500 tops torque (at peak) is possible with the right setup on that motor. if your looking for torque then i'd stay far away from any japanese engines and go with something american. A 6.0 iron lq9 from a 99-current chevy truck would easily get more then 700 ftlbs torque and more then 1000rwhp with the correct turbo setup.

what is this car going to be used for? honestly 600+ rwhp in an s-chassis will be a handfull and anything more then that would really be pointless since this chassis is too light and not designed to take that much power.

[MastaYu]

sounds like fun what are you planning on doing with all that tq. ? Drag race?

Race wars are comming up.

WTF?the funny thing to say when you havent build one bro.hey little supraaa lol want to play?.they go for 500hp on stock same as 2jz s.lol.but ill give you the turbo isnt what I want I will be getting a gt42 or a VG turbo with some 1600cc injectors.Ive run the gt37s and have nothing but good things,of course I ran it in my evo 2 with a 4g63 talon engine,the unly problem was the lag,but since this is a six it shouldnt have that much lag right?ah....fck it ill go for the gt42 and the car its going drag and drift sow yes its getting some goodies done as you read this threat.and its got a aeromotive fuel setup sow its got the juice.to make it better and keep all that juice cold its a alcohol injection ya now.lol.american yeah my @Slol

american ur *** eh? show me 1 rb25 or 26, a 2jz, or any 6 cylinder import engine that makes 750rwtq. there is no replacement for displacement. Fact is you wont make 750rwtq or anywhere near that with ur rb25

[low91240sx]

I think you better make it a TT if your thinking that much hp/trq and honestly even then you may not even get in the ballpark that you want will def be a sick/quick ride but that's a lot out of a Jap engine like stated above if you want that much hp/trq you might want to think about putting in an american muscle engine bud

[gismonismo]

god ls1jupiter no faith ah?its no a dream,its a fact.I dont have to show you @#$ man.you find it your self,mucle cars are cool if your into that congrats!!!!!im building this S14 never thought itll be to showing the world whats a RB25det capable of.wow do your self a favor and dont post here jupiter.seriously dont.no one has a stoker kid on there rb25?and its 675trq. witch will be done with 22psi ill have the data posted here when its done ok later

[allmotoref]

2jz 3.4 stroker kit ftw

[gismonismo]

ok ....lol.no offence but why are ya here talking about 2jzs man, yeah there good so as rbs,but never mind that(you).If I wanted to build a 2jz I would have done it already and its such a shame that asking for a little opinion turns to this. My opinion is that if you want to go big on a rb stroker is the only way to go.and please dont post ya crap about crank problem on high revs.its forged every thing on the bottom collar yeah...now if you stroker a rb25det correct your fuel and maf(ems) timing ect plus a huge turbo set up,500hp is easy as 14psi,and it comes as soon as it hits that number 3 on the rpm gauge.lol.yeah fact no dream.all I'm saying is that support the cause.dont hate.give me facts no wet dreams about 2jzs or rb26.all I got to work right now is my rb25det.please stick to the topic.

Now back to the subject:I understand that aiming for 700hp I can port and polish the head with some mild work on the intake side and a good one on the exhaust side.what do you guys think?and still havent come up with a good lsd for the stock 240 rear end,Im thinking of getting the stage 2 drive shaft shop axles.(no j30s please opinion)please!!!!..lol.will a carbonetic lsd and custom axles cover this much hp?I already have a aluminium drive shaft in it now

[Ls1pwr]

lol you are an illiterate moron. 1st off its ls1pwr not ls1jupiter..... 2nd all these so called "facts'' are no where to be found. Please show me these bs "facts" that your talking about. You are a joke

[low91240sx]

well I will be the first to tell you that I don't know much about the RB25 or it's capabilities but I do know that when built/tuned right they are flat out mean engines there is no reason to sit here and go back and forth and call each other names just do what your planning and see what you come up with bud. It will definatley be intresting to see what numbers it produces go for it man as for your other questions I'm not sure bud like I said I don't know much about the ol RB25 just here supporting your build

[ANVIL]

u would probablly get more help and some better opinions from people with more knowledge on this if you posted in the rb section.

it doesnt sound too hard of a goal to accomplish as long as you have the time and money. but you would need a better choice of turbo, and bigger injectors.

[visser003]

Im no expert, but I would get nervous trying to hold 700rwtq with an aluminum driveshaft. i would go with steel running that much power.

[Carl H]

Worst rb related thread evar.From the hideous grammatical errors to the down right atrocious spelling I doubt you have the capabilities to produce 675ft/lbs out of an rb25.Considering that torque is a byproduct of stroke as well as displacement of an engine you chose the wrong engine.

[l0nestar]

Spell Check.. USE IT!

Worst rb related thread evar.

For Truth!I dunno though.. I have see a few 'jems'.. *sigh*

I guess this is what happens when you have no clue who your talking to ,http://skylinevideo.vidiac.com/video/20 ... 8b.htmhere you go .guess no help only bad jokes ah?sorry .lol. the car runs 9.93 at 140.67mph and right now its over 800rwhpIm not falling for your sht manbesides who gives a fck what you say or think man.

I dont got time to btch about things..man.. Im a builder not a talkerIts all good in fl low91240sx thanks man and all you who have common senceI'll give you guys an up date soonalso ..my set ups.hey..anyone knows about the brian crower stroker kit?its says it goes to 2.9 anyone?

the worst part is waiting for the parts. shipping sucks here!

im sure you can do it, thats a **** load of power but if you can come back with a dyno sheet an prove these people wrong all the better for you my friend.

[gismonismo]

question anyone knows some good cams for rb25det.?I'm thinking of getting a set of 270 degree duration 10.25lift?I need to order them soon. my head should arrive soon man.

thanks bro.I will need to tune it Ill see if I can video rec the dyno run.

Seriously.. What is the point of this thread?

Your a builder not a talker? LISTEN TO YOURSELF, READ YOUR OWN POSTS.

try living in Alaska

[gismonismo]

first im not a know it all sec.Im no pro builderthird I ve build my projects in my garage just like everyone else(of course some of you have made it big time)not me and I can give a shtfourth Im not better then any of you.

Yeah I have made some money on projects that I have custom made and design for aerodynamics for some guys but just to get some cash to finish my projects

yeah I have worked on fast foodsand I have been down lost almost every thing to a divorce and fck alaska.

does some one actually know about rbs here or its just sad mfs trying to make a statement.

you dont like the thread dont post or go to church

[gismonismo]

bye bye old set up.

soon new set up.proyect has changed thanks to haters .lol.now its 800hp+plus some nos set up.

soon...

[sviellvoicae]

looks like a raw *** build man. the motor in it now looks pretty crazy. more crazy than alot of people on here or at least the people talking now. your better off staying away from places like this when you have goals cause everyone is a hater. mostly hating because they dont have it. i have seen some crazy **** in my day. suzuki aerio with 450+hp on the aerio 4cyl block and still runs strong. now you tell me that it is impossible to reach what he wants wit a rb25 good luck wit the build man hope it shuts some douche bags up.

[gismonismo]

thanks man.when they sayed that was impossible to make 700 of torque on a RB25det you know they're full of it,all they do is repeat whats been sayed .thats no way to go.doesnt mean I think that the guys doing low numbers are and working on low $ proyect dont know nothing.I actually respect that.Thats were I come from and will always be there with me.as for the proyect.I'm having one problem,oversize valves or not?money is running low right now.I sayed this proyect will cost us 33k but Im almost at 24k and still havent started the rear end.im stock with parts that take forever to come and the never ending ported head.lol. then i have to take it to monster motor fab.to get the mani and down pipe custom made to fit that gt42 and the two 50mm waistgates set up.itll probably go for more then the 33k limit.the engine alone its taking half of it.suspension took a big chonk out of it,with the megan everything,plus the rear OZ rims used but never to regreat.welding the front frame and fire wall to aid the stiffness wow......its been a long 2 months since we started this proyect......hey look att it when we got it.lol.beforeafter...lol.I toke the car and drift the @#$% out of it before we started building it.lol.goo old days ah?lol.

[RB24D]

Your project looks good! I am also shooting for around 700+ hp not sure what torque I will get .My engine ( a motor is electric) is at the machine shop currently getting some goodies put in .I am using a gt35r turbo due to wanting to street drive mine . Keep up the good work.and keep us posted. And for god sake man pleeze uze spell chechque !! lol.

lol how am i full of it??? looks like you have alot of money and not much common sense. You still havent shown me a single rb25 with anywhere near 700 ftlbs torque, and u know what??? You will never find 1. That video u posted up of the fastest gts-t was all fine and dandy but that doesnt have 700 ftlbs. that car is fast YES, 700 torque NO!!! show me an rb25 that has that much torque PLEASE PROVE ME WRONG.

[gismonismo]

hey man do you know I build my own carbon fiber parts?you see that hood made by meyeah...but you know?If you need some stuff pm me man.like a hood fender let me knowIll hook you up man,oh and bring money

[Ls1pwr]

oh man what was i thinking?!?!?!?! if you build ur own carbon fiber parts then of course ur car will make 700+ ftlbs torque. geez i feel so stupid, and if i ever come across a hoodfender then i'll definitely have it made out of carbon fiber from you.

lol still waiting to be proven wrong on ur magical 700ftlbs
