Look man, It is simple I have done every possible thing I could to this motor to reach my goal. I really do not understand your static but if you want to know why i did it READ. Period.

I do not have to justify the modifications I made to my engine to you. I really do not care how much you know or think you know yes there are some downsides to any modification but for what I intend to do with my car I do not see any downside as top end is EXTREMEMLY important for what i am trying to do.

Take the info I have given for what it is just some info you can use it or not. The one thing I DO NOT want to do is sit here and debate the merits of my project with some guy I do not know and has not established any credibility in person with me.

You want numbers Go Pay for them and get some and do your own comparison. I have rode the line on RB26's and Rb25's and did not want to do it again so i did what i did. I will be glad to post up some dyno numbers AS SOON AS THE ENGINE IS IN A CAR. Expect about 9-12 months before that will happen though.

Now can someone lock this thread it is ruined

thank you for making it clear you have no clue why removing the quench pads helps in making HP.

its clear that you ride bandwagons as hard as anyone, seeing as you throw money without regard to simple physics. well FYI it isint hard to make 900hp on a inline six turbo.http://www.suprastore.com has a nice900hp kit for sale. oh ya supra's have quench pads o wait, v-8's have quench pads! ****. everything has quench pads. they must BE THE WORST THING EVER DESIGNED.

this will be my last post on nico seeing as your the prime example why forums make people duller, not sharper (those are some shiney parts, i bet that makes them fast!) and why nico is generally regarded as a ****hole.i gues i shold have listened to the people that said that before attempting to get any DECENT information from this site, other than "look at my shiney parts!" and "what size turbo do i need?!!?"

adios

I know who is building his motor and he knows what he is talking about. He build things like this for ****s and giggles. http://www.sdsefi.com/features/jan064ag ... 2tommy.htm

If he advised cursed to do it there is a damned good reason. Were he to uncharacteristically give two ****s about your opinion and actually have enough disdain for you to spit at you I would reccomend you rub it in and hope that you got smarter by osmosis.

If you want to leave you are welcome too. Kind of like the kid who picks up his ball and goes home when the other kids won't play by his rules though. Your choice, I will be happy either way.

GOOD. YOU ARE A RETARD. 2JZGTE's and most V8's DO NOT NEED TO REV ABOVE 10,000 RPM to make 900 -1,000 hp. Most RB26DETT's do, since there is about a minimum of 400cc in displacement in difference you are talking apples and oranges. Talk to me about the RB26 not the 2J or some V8 that I could care less about.

The shiny **** on my motor is a just pride. I do not put over 20K into a motor and not make it look good too. Since all of that was done by my hand and a friends air brush you again don't know what you are talking about. Hope you can take your arrogance somehwere else and succeed with it.

If you decide to leave NICO that is great, you really served no purpose and added nothing to tis thread.

Time will tell I quess whos makes better hp and how. But for now I say cursedgtr is in the lead on doing it right. You gota try things to see if they work. If your going all out and putting a rb26 in a s15 most imes you would have the engine painted and done up. What kind of oil pump do I spy cursedGTR? Just back off and sit back and read. You will gain more by waiting and seeing there outcome. I was palanning on reshaping the combushtion chambers also. It looks like good work and in high boost engines you most times dont see the quench pads.Do what you want to do Plz DONT BASH OTHERS FOR THERE HARD WORK! If it fails you can get the satisfaction in the long run and snicker to your self.

Could not have said it better at all.

You spy a Nismo Oil Pump S14.

I promise to put up some numbers once this thing is done and dialed in.

From a performance Standpoint... I honestly never got the whole RB26 into the S chassis. Dont get me wrong you're performing amazing things with the holy grail of motors. But in my experience (with the S13/S14) much more HP over 350 produces massive wheel hop. Granted with the RB26 its a lot easier to get to that 350 mark but you upset the balance of the S chassis in the process . Congrats on an amazing engine, swap, and chassis

I did the whole skyline thing for a while and decided I didn't much care for skylines as a whole car. Do not get me wrong, I like GTR's and all but they are a huge pain in the *** to keep on the road once they start aging. Also, I did not like how complicated everything was. Originally I was going to do this build for my old R32 GTR. But I kept on looking an looking at the S15 and knew that I would want one (they are jsut sexy cars). I am not too keen on the whole SR thing, just because I am comfortable with RB's, so I decided to go with a RB26DETT in an S15 Chassis. Of course the motor is going to throw off the over all balance of the car a bit and some things are going to be out of wack and will need to be adjusted. There are going to be somethings that cannot be compensated for, but in the end, I feel I will reach my goal of a 200 MPH S Chassis. Time will tell and we will see if I am able to make my goal come to fruition, should I accomplish this it woul be way cool and a personal feat.

[cdorhout]

It's all about trying something different and you surely don't see many RB26s (especially one of this caliber) in an actual S15. Props!!

Most Definitely!!!! Wow if you hit the 200 mark you gotta take me 4 a spin!!!!!!!!!!!!!!!!!!!!!!!!!

[themadscientist]

OMFG, the mythical "balance" issue again. Good lord let that **** go already. It has been a lame argument from the first time it was used. I have ridden in a 600hp RB26-powered 180SX that a buddy blew his whole re-enlistment bonus on and the balance was fine. He couldn't get the thing to hook up for **** but considering it had nothing but a set of coilovers 7 inch rear wheels and his driving sucked he would have had the same problem with a 600hp anything. That engine in a RWD Skyline with worn out suspension and a ham-fisted driver would have done the same. Now B, you killed a palm tree with the Skyline, what are you aiming at with the Silvia?

[redtop91]

^^ debateable but this isnt the time or place

Sweet ride anyways

I really don't see any points to debate. Of course putting the RB in the 240 in place of the KA will change the center of balance, that's basic and irrefutable. The change is negligable though so while it may be true it is merely of anecdotal value. The way CA, SR and KA guys cling to it as if it were Mr. Miyagi's crane kick "no can defense", is silly. The S-chassis has the balance of a lawn dart to begin with, that's why it swings so easily around that foward point of balance. Moving it foward a few inches means nothing. I have always preferred the Skyline's more neutral balance to the S-chassis because I like high speed and the 180 gets spooky at triple digits. For drifting I would go the other way because of the light ***, it breaks easy and in a linear fashion.So in summation, no debate. It does change it a bit, so what.

[redtop91]

the 180 gets spooky at triple digits.

couple the S chassis, lightened, with low performance tires and you've got one seriously scary whip. As regards the whole balance thing whatever... anything from a full tank of gas to eating a quarter pounder with cheese can upset balance. My main point still exists in that you can't build the RB to its full potential and expect even half of its power to make it to the ground in the first two gears in the S. But from the standpoint of doing it because it can be done is freakin awesome. I'm not biting him for choosing the RB because I'm building an RB26 S14 but it is for show.

[themadscientist]

I have seen what you speak of first hand, it is quite a whiteknuckler. There is a Silvia locally that cranks out low 10s in the quarter with a serious 26 in it but he fights the traction issue. Even with big gumballs and well-set suspension he has to pedal it to keep it from going up in a cloud of tiresmoke. Any serious attempt at the the 26 in a S-chassis for drag work should really start with back-halving the car. HKS used to run a tubbed 180SX with a 26 many years ago that could bring the pain.

hahaha....case in point

[redtop91]

OMG I'd love to ride in an RB S13 like that . How is the S15's cabin? spacious but racy?

[CursedGTR]

O.k. so we have rendered the balance issue moot. Which rocks, because I was really not up for that argument.

Mike - I aiming to be a skid mark on the road this time around, because if I wreck it I will suck start a shotgun with no hesitation.

it would be really cool to back half the car and make it a dedicated drag deal but I would like to try to accomplish this without doing that. Mainly because I do not intend to only drag race it. I have the silverstate classic in mind. I figure with the right offset and the widebody kit I am putting on it, I should be able to get some pretty decent meat on the back. We shall see though, it is only a matter of time befre I get back to Okinawa, get back to work and finish this thing.

The S15 Interior is pretty nice. I woud not call it spacey but it is definitely nice.

[themadscientist]

You might make the beast more manageable with higher gearing in the rear. With the SSC it's about the top end so with some highway gears in it the Silvia would not be so beastly on acceleration. A close ratio box would keep you in the sweet spot for the sections where you would have to bring it down from ludicrous speed for a minute or two.

[CursedGTR]

THat was the plan. I as intending to run a PPG close ratio box with a decent final drive gear, I have not decided which way to go on it yet but we will see when the time comes and the conversation with PPG on what they can do happens.

[CursedGTR]

I am back from the sand box and have started on the chasis. I will post pictures here in the next few days.

[USsil80]

welcome back from the box... i almost went there for tcn duty but they said no becouse i am still in my cdc training....motor looks awsome.. what other post about the motor- would like to see that

[CursedGTR]

So I have the S15 now and I am doing a paint job inside and out and trying my hand at some sheet metal work too. This is the chasis in the past ew days and its progrewssion. When it is all said and done, it will be wearing a BN sports widebody kit and some other cool goodies (an 8 point safety 21 roll cage is one of them). This whole project is long, involved and definitely a learning experience but it is fun and well worth the time invested. Due to the humidity here, you kind of have to prime as you go which is a whole new challenge but hey, rust is rust and I hate rust so I will do what I gotta do.

[Darius]

WOW now that is what you call a "grass roots" project. That baby is steeeeripped.

Looks good so far. Is that fender flare on the rear quarter panel part of the BN kit?

[CursedGTR]

No, it is not part of the BN kit but the fender flare was put in to accomodate wheel travel when the kit is on. Normally you would cut the quarter panels, but since I intend on taking this thing through inspection to get the title changed to reflect all of the modifications, it is best to leave them flared (The japanese inspectors do not like the quarters being cut for some reason). The BN Sports widebody hangs over that flare by about 3 inches so it is never seen and is pretty close to the apex of the wheel well.

[Sil240]

Nice work.

Body work is wayy to PITA for me.More power to you!!!

The chassis was it a Junkyard car or did you buy it and Molest it.??

[CursedGTR]

It was a shop car a while back and I bought it mid swing during an upgrade they were doing. So in short I molested it like chester on a 12 year old boy.

[l0nestar]

(reply to pic of your assembled engine on the first page)That thing is pure sex man! Too bad you couldn't use a clear timing cover and had to hide those beautiful HKS gears and belt But it would have thrown off the whole paint job so I understand But still, beautiful man! I actually saved a copy of it for a background. Good job man!

PS, your S-15 looks pretty slick too! Keep up the good work! Oh yeah, more pics too!
