potential

[tgood]

I'm new to the import world and i'm 15 and this is my first motor swop. I would like an RB20 or an RB25, but i don't know which to get.The Rb20 is cheaper but i hear thats theres not a lot of aftermarket. The Rb25 has a better aftermarket but cost more and is harder to install. So can i make about 400 to 500hp with minor bolt ons for the RB20 or should i get the Rb25. sorry so long

Minor bolt ons consist of intake exhaust and boost controller. None of which will get you close on any of the RB series. But if you swap turbo's and upgrade your fuel/ignition system, the RB20 can put 400 hp without to much trouble. I'd suggest swapping your pistons for a set of forged babies, the ring lands will hold up better under alot of boost then the stock units. The rods will be fine if you keep the revs close to stock. If you increase your rpm range by more then a few 1000 you'll want new rods and better valve springs.

All in all, to get 400 hp your going to need quite a bit of boost. So your going to need quite a bit of fuel to go along with. Before I recommend big boost on an exotic engine, I'd suggest doing some reading to become familiar with forced induction in general. Get a copy of Maximum Boost from Corky Bell. Great info, I'd say its a must read for guys going with boost.

As far as parts go, anything can be made custom and if you look around, most can be found for a good price. Custom cams are about 350-400, have your intake head and exhaust sent to extrude hone, worth 75-150 hp depending on how much they do and what boost you want to run.

If I were to swap out the KA, I'd buy a RB25. Its a simple matter of cubic inches, more cubes makes more power. But i'd take the RB25 over the RB26 also. Simply because the RB26 is such a PITA to work on, especially if your keeping the stock turbo's. Anyway I'm rambling now...its a rough choice, if you worried about money and want to get the RB20 cause its cheaper, then you might want to take another look at your HP goals.

Let me do you a favor, before the Search Demons get here!!!You're 15 yrs old. 1st you need to learn how to drive, and get better at it, There's tons of driving schools. I heard BMW has a good one.

Star with something small and work your way up. Start with a N/A car.. Really build up your experience.. Once you 3-4 yrs of driving experience, then dive right in.

Once you're boosted, Try 300hp, you will see the car will be a different breed/monster. Get used to it. Then up the HP once you're confident enough.

Sorry to sound Like a Dad. But I don't want to see you waste your dollars and your life with a car that you won't be able to handle....

start with a 240sx, basic bolt ons, and suspension upgrades. Get used to the car.

[IvoryJ30t]

on an rb25, 4-500 hp is beyond simple bolt-ons. at that level, your wandering into an area that requires extensive tuning and a fair amount of knowledge.

not to say that that power requires internal work, but you dont get to that power level by slapping things on here and there. you have to do your homework to get it right.

and on another note, find someone who would be willing to let you drive a car with that sort of power. those numbers sound good on paper, but with an inexperienced driver piloting that sort of machinery, its disaster waiting to happen. im not trying to sound like your parents, but jumping head first into that kind of power will land yourself and others in the hospital.

wow, 4:25, 4:26 and 4:27...you guys are so slow...lol.

hehehe, never did take any typing lessons or such. I was just making sure of spelling errors and such..

thanks

A 15 year old shouldn't be driving something with 4-500hp IMO.

But if your wallet can handle it, go for it! Don't kill urself!

WHERE ARE YOU GETTING CAMS $400.... OR IS THAT PER CAM?

ANYWAY WITH HEAD WORK, EXHUAST, FMIC, INJECTORS AND A STANDALONE YOU ARE PROBABLY NEARING THAT RANGE BUT ITS ON THE LIMITS OF THE MOTOR AND WILL TAKE EXPENSIVE TUNING.

[NISMO_RB25]

Something to remember is that you are putting the motor in a car that weighs less than 3000 pounds. You don't really need to hit 400-500 HP to beat a car that weights 500 pounds more. I am very happy with how much power my RB25 makes and other than an exhaust, I don't have any power adder mods. The car is rediculously fast already.

Without a LSD, I am spinning one tire through all of first and second gear, and most of third. I have been driving for over 10 years and have had my share of fast cars. You will not be disapointed with this one. 250HP in a 2800lb car is a wonderful thing. 300-350hp in that same car will pretty much smoke anything you will ever find on the street.

You guys are all jealous. There isn't anyone on this forum who doesn't wish they could have done this at 15 years old.

I have a machine shop who does my cams for the KA, they run about 400 for both depending. So I imagine a set for the RB would be fairly close.

OHH OK COOL.... SO IF I GAVE THEM CAM SPECS THEY COULD BUILD ME CAMS?

I am not jealous, just realistic. I am glad I didn't have a 400 hp car when I was 16 and learning how to drive, or I probably would have died.I had a full size 4 wheel drive Ford Bronco. Only being able to drive 80mph saved my life more times than I can remember. I had 3 different cars crash into me without getting enjured. I ran over a 250lb wild hog at 65mph and didn't even scratch the bronco.

[Wulfgang]

Ok, I stand corrected. I, for one, sure wouldn't have minded being given a Viper at 15. But then, I had to drive my parent's minivan, so maybe I'm warped.

[Project240]

Yeah, for real. I had a couple near-disasters at 16 with my '82 Trans Am (that's 145 raging horses, woo hoo!!!! ), I can only guess that I wouldn't be here today if I had a car that was ~700 pounds lighter and ~3 times more powerful.

[Wulfgang]

No, you're right. You wouldn't be here. You'd be on a Viper forum

Hi!! I couldn't think of anything constructive to say so I just posted a bunch of crap instead. I like Tulips and daisys bestest of all flowers.:pface

This thread has been cleaned, if your post is missing, its cause it was garbage and I deleted it. Email me if your panties are in a bunch.

No Nube bashing...I had a 2 door 77 Caprice Classic with a stroked SB400 for my first car. It only had 390whp, but immedialty went under the knife. I was clicking of 12's in the 1/4 within the first year. Which is great considering the 4200lbs the car weighed. I was 16...nuff said about that.

Dreams are what keep us goin in life.

Tgood, your in Dallas I noticed...My car is at the exhaust shop now but as soon as I get it fired up and broken in I'd be happy to take you for a high boost drive so you can see what >300hp is like Hit me up with an e-mail and I'll let you know when its ready!
