Really? With english and grammer like that, you are calling him retarded?

You opened yourself up for this flaming. Don't come on a public forum spouting about building and engine with unheard of power and expect people to take you serious.If you really want to look like the stud you think you are, stop posting and create a thread with your dyno sheet to your super motor you built in your head.."I can build a 350 HP Chevy Sprint 3 cyl motor. If you guys don't think so, you're just retarded"Talk is cheap, intellegence is priceless. Build it, dyno it, and make us all eat our words!

[gismonismo]

Every thing I didnt know I learn it from the tec forum.I build my cars by my self.theres some nice stuff here and some of you know about rbs.I thank you all for your support and help. if this threat is still open when I finish Ill post the finish product.Im out.hope you all can build your dreams and make it big.thanks nicoclub

[Fractur3]

man dont listen to everyone out there. Your build sounds like its gonna be sick regardless, but seriously, 700tq? 700 hp will be hella fast, but in order to make 700tq your talking 1000+ hp to the wheels man, in fact i dont even thing its possible.. not trying to shoot you down or anything, but im just saying thats gonna be a ****load of money as well, your gonna need a whole new transmission to support the power as well as axels and driveshaft and ujoints and all that stuff.. just some food for thought...

im not sure if you've thought of what turbo you want, but check out the forced performance t4z 88 HTA (aka HTA47r) its basically a gt37r with a billet compressor wheel or something like that to quicken spool. I know a guy thats big in the evo/suby world that has a custom pieced 37r that spools faster than a 35r and clearly hits harder if you want more info

HTA's are way popular in the evo/suby community, idk why they havent made it here yet

[MS180SX]

not that i want to jump in on this great thread or anything, but im pretty sure there are 1000hp+ rb's out there. i know theres some vids on youtube of crazy fast rb's, try looking at skyline from hell.

and in my opinion, anything is possible with enough time and money. if you canhave a 7 second street car, you can get a 1000hp outta an rb.

hell, AMS has 1000hp outta a 2.whatever liter evo motor, a 2.5+ will def do it.

try full built bottom endfull built heado-ringed for higher boostmassive turbo/fuel setupc16 race gasmaybe some methanol injectionperhaps some nitrous

with some imagination, time and money, you can def get 1000+ hp and prob 700+ ft-lbs.

im there with ya, only im a few couple 10K's shy of my goal..haha

[Fractur3]

race gas + meth = useless

the whole reason people run meth is to raise the octane of pump... not that its not been done before, but its redundant and most tuners wont reccomend it on race gas. pump is a different story.

nitrous (depending on the shot) is just asking for something bad to happen lol.

but hell if you got the money and want 1000hp, im all for it man go for it.

[emo_tactical9]

Good luck drifting with that setup.Seriously, you would have been much better off with a 2JZ or a LS1, since all you want it a dyno queen/drag car.

[gismonismo]

ok ill start this one more time and sorry for the bllsht thats been talked here and if I diss some one sorry and hope were cool man.heres what I got sow far.The head was taken to my freind Ian att Monster Motor Fabyeah valve vale springs retainers cams dont know what his doing but hey.I trust this guy with my live.he told me to be reaady for some power.ill buy the pistons and ruds with acl lateralready have the cometic head gaskethead studsmain studsjun crank collargreddy timing beltdry sump pump with custom bracketsredrilled oil drainers and a oil restrictorsstill waiting for the dry sump catch tankand the oil cooler kit from greddygreddy oil pumpthe fuelsimple2ltr surge tank tsunami external pump witrh doal filters 8 lines 6 return linesplus suge gets it from the walbro in tank pumpwent with 800cc injectors and a going to run the at 12%duty with methso if I want to go for bigger ones all I need is to swap them

for transmission Im going for r33 rear end custom axles since I already sold my aluminium drive shaft and replaced it with a metal one DSS

I was thinking of running what some guys call a drain line? they say that its a drainer line that goes to the head to the bottom?have no idea.anyone knows whats thats all about.pics will do to

also my goal is 600 of torque signalauto told me not to go over 1060hpmy axles only handle 700hp and my fuel should be ok for that num.turbo its t78 maybe still havent got there.I already sold my gt35 turbo kitnow I got a custm mani with a 46mm waist gate.still thinking about the turbo.

some goodiesstill havent got back the engine head waiting....?

[ilovesideways]

Hey looks like a nice project and to me your goals sound realistic. Don't worry about the haters some people just can't get there minds off of american engines (which I mean if american cars are your thing thats great but not when they are put in a japanese car ) Sounds like a pretty sick build though hopefully you can get some videos up for us to watch of the first run.

[gismonismo]

thanks not thinking about numbers now,Whats a shame is that the ones who have this engines are more in the stock form.thre for others belive theres no way the rb24det can perform high hp num.I can go up to 900-1000hp but im not building a dyno queen here this is more like a shut the fck up and come race.lol.build perfect,brakes,T responce,balance and wieght.set perfectly.beside over that and its just a supra no traccion

[gismonismo]

well the block is at the machine shop + crank and now Im focusing on the head rebuild since my friend just toke it to the machine shop and they only cleaned it up(thanks pal)I got a great price on tomei 270s 10.25 for the solid convesion also some tomei springs and retainers.Thanks Nigel att AU.

since the end of may when this proyect started I had build it by my self.my only hope is to have it finish in the end of october.Solid lifter has its pros and cons but its the only way to far more hp then hydraulics.also planing to buy a welding machine.So i only have to take it to the machine shop and do it all my self.From Aerodynamics to custom welded parts.Saves a heck of money

[RCA]

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

http://www.youtube.com/watch?v=im1oKedOV4s750WTQ isnt unheard of from an a 4cyl or 6cyl but in all honesty too much TQ makes driving less fun.

I mean yeah sure an LS1 can make 700hp and 750tq but good luck putting that to the ground buddy. Unless the car rocks 375/20/xx mickey thompsons you wont be able to do any thing but spin.I would take 600hp 450tq any day.

Best of luck gismonismo.I agree if you created a TQ goal...Then this engine isnt the best choice. To each his own and best of luck!

Prove those nay-sayers wrong!

[Ls1pwr]

lol i never said it was impossible to get that much torque from a 4-6 cylinder. don't put words in my mouth. that was a 1800+ hp 2jz with a 1,500 rpm power band....... drag race engine designed to be run a couple times then rebuilt. what i said is that your not going to make that much torque out of a rb25. And i still haven't been proven wrong.

...honestly your goal will never be reached...

[black240sx96]

lol...sounds like someone is going to be eatting their words for lunch...i want to see it too....if he does get that much power i want to see the video of MR. LS1 all american in a jap car print what he wrote and put it on a plate and eat the page/pages....all of it....

"there is no greater feeling (besides getting laid) than showing up everyone that said you couldnt do something"

[gismonismo]

I went to the solid lifter conversion,270 tomei cams and springs.to high rev the rb so....I can go for the bigger turbo.the block its not getting any work until my crank collar arrives.but yeah all the aftermarket parts are in my garage.all I,m missing is the turbo and the valves.I just haven't decided which ones.open for sugestions you know on valvesas far as the 1500hp dyno queen is just that..you should worry about lubricating you mouth to make it easy swallowing your bllsht about rbs.

also dont worry about traccion Have a friend with some M/Ts and light american racing rims later.I have some kills to do before I sell it

Is this for real???? Almost sounds like this is one of those jokes, like I got the gtr badge to add 25 hp or whatever. It jumps around way too much. I cant follow, maybe I am just a dumb redneck. I would love to see it happen, if it is for real tho!!!good luck for ya if this is a real build.

[gismonismo]

waiting for mazworx to send me how much itll cost to do the convertion since I have no experience in such installs such as solid lifters.Yes my friend it is very real and thanks,You know?theres not much options for those who want to make big power on the RB25det engine and prices are up the roof man.No wonder theres not much of us going all out on this engine.But we will soon know if it worth.I have to make over 800hp to reach the toque spec num.I know I can hit 600torquebut how much more.I dont think I can hit 700 of torque since even 600 is insane theres no use.....but then itll be a matter if I can put that to the ground with out crashing.lol.after break in ill do the 600 sht and retune it to street mode.

[gismonismo]

over sizes .25 vs stock rb25det pistons

[leonelrr]

Good luck, bro..

I think that's quite a TQ from a 2.5 inline 6 but then again if you are able to get that much torque.. Then everyone will want to know what your set up is..

Anyways i am getting an R1 so you can't touch me! LOL

[Ls1pwr]

lol ill sell my car if u break 650 rwtq.

[gismonismo]

lol cant belive you will do that.By the way what are you rolling?Dear Ls1power.

But dont sell your car man,you just happen to fck with the wrong person thats it man.Thanks to you I wont win nothing out of the sell.I should hate ya @S man.lol is not like theres some one that will pay the 31,865.36k I have spend to make this proyect so far.You guys will gain out of this proyect not me............fck!

[tavarish]

anything's possible, but at that power level, don't expect anything remotely reliable. You're testing the limits of many components of the engine, and from your posts, it seems like you don't have a clue as to how to get your magic power number.

I myself have a 1jz, and I can't fathom 650rwtq, especially on a stock crank and block. Forged internals are all well and good, but you have to realize where the powerband is in the car, and with a gt42 and 2.5L of displacement, it'll be narrow as hell. if you want a car with good throttle response, I'd suggest a t67-t70, and you can push great numbers all day, and have generally good spool time.

I don't think the numbers will be reached without nitrous.

You'd also have to push the turbo to 35+ psi to flow the amount of air you'd need for your numbers, if all things hold.

[Nurokil]

Gismo, I get my 180 today. After getting it back to good running conditions i want to meet up with you when your RB is running. I live in Volusia. My buddy just got his 180 going after a complete rebuild of the redtop. we hoping for arounf 350-400 at the wheels.

[Ls1pwr]

its a dream.... it will never happen, thats why i said i would sell my car if he made it. i know its a safe bet lol.

[gismonismo]

to reach that amount of torque the engine must go 800 plus hp which means over 36psi.thats when the solid conversion comes to play. Those are nice turbos especially the t70, but I have not decided which one. The t70 is out of the question. More like T04 or a t51r. Ball bearing it's a good way 1.0 A/R or little less, not a .70 A/R. gt42 its gone alone with the modified gt35 and the stock crank is good for all I know they have been pushed to 900hp with no harm, but thanks man..........tuning its the key

about the meet up sure thing man. pm me hope it will be done by the end of oct.remember this engine will need a break in.After thats done comes the tuning.Signal auto has given my thumbs up for 1040hp.but itll need bigger injecctors like 1200cc or 1600cc.not good for me I don't think anyone can handle this car on that power level.I drove it att like 400hp and its a handfull.after The the 600+ torque has been reached its back to 600hp all day.Sorry this car will be up for sale to make room for the next proyect.but i love the car it handles well true sleeper

[WizardBlack]

Sorry, dude, but if you can't figure out your own turbo, can't figure out your own cams, asking ppl on a forum what to do, etc. it probably won't happen. Yeah, you can have other people tell you what to buy, have people do the actual build for you, etc. All you did was whip out the plastic. However, don't come on here like you are mister badass without even a high school equivalency degree (based on your spelling, punctuation and grammar) and then act like you are surprised you got this kind of skeptical response.Likewise, first you are talking about making 750 wtq at 12% duty cycle on 1600 cc injectors (like to see that) and then you say 750 whp is proven. Not the same thing. To make 750 wtq you will end up with about 900 whp unless you stroke it or use some sort of monster nitrous kit.Can you buy the parts? Yes. Can it be done? Yes. The margin for error is very small with a 900 whp 2.5L motor with dry sump, etc. The parts are irrelevant. It's the maestro pulling it all together that makes it or breaks it (literally). I think you need to find a tuner that can put this together for you. If you have one, you should be asking them and listening to what they say.

To another poster: the powerband doesn't have to be that small. It's all about using a GT turbo with a bit better spool and then running 30~40 psi or more with the highest octane you can find. Nothing against the 2JZ, I love it (and built one of those before, as well), but they have uncharacteristically poor spool for the engine size/rpms, etc.

[Ls1pwr]

please enlighten me, what the hell does this mean in english???

"The t70 is out of the question. More like T04 or a t51r. Ball bearing it's a good way 1.0 A/R or little less, not a .70 A/R. gt42 its gone alone with the modified gt35 and the stock crank is good for all I know they have been pushed to 900hp with no harm, but thanks man..........tuning its the key"

THIS LINE IS REALLY FUNNY TOO:

"itll need bigger injecctors like 1200cc or 1600cc.not good for me I don't think anyone can handle this car on that power level.I drove it att like 400hp and its a handfull.after The the 600+ torque has been reached its back to 600hp all day.Sorry this car will be up for sale to make room for the next proyect.but i love the car it handles well true sleeper"

hahahahah u finally realize that u will never accomplish your ridiculous goals and now u give up rather then admit u were wrong. I HATE to say it but, I TOLD U SOO!!

[gismonismo]

lol.t70 is the A/r .70 of his turbo they call them t70.garrett t04z sorry and the other stands for HKST51R ball bearing,........do you understand? Dont worry Itll be done before you can say cat in the hat
