1st off get the swap done. Most everyone here will agree with me. Run it for awhile and see how you like it, before you jump into a turbo upgrade you should be setting you eyes on the following:

3" ExhaustFront Mount IntercoolerBetter IntakeWalbro 255lp/h Fuel PumpKoyo Aluminum RadiatorClutchNismo(or your brand) Fuel Pressure RegulatorBlow-off Valve These basic bolt on will give that motor a little more kick and steer you in the right direction for future mods. After these are on and you have the car running good then I' be looking to upgrade Fuel Injectors, Turbo and A Standalone EMS.

One other thing we don't discriminate on ppl cause of sex, we are all here for one thing the Love of Nismo power! You learn taht most ppl here are will to answer any question, troubleshoot with you, to steer you on the right path! Any more question you can reach me on AIM: chaosthexile

unless you have experience building these cars and motors just drop the motor in with a STOCK setup and go from there...its alot less of a pain in the *** to trouble shoot a stock setup than one that has been highly modded.

[SeVa-S13]

GT47R right off the bat or you're a ricer.

Oh, and zerothread/183574

[Yellow4g63]

I'll have to disagree with everyone here. Fark that stock turbo, change the turbo right off the bat becuase it's just a old POS turbo. Pick up a 50trim T3/T4E .63 exhaust A/R and bigger injectors and a 300zx maf. Rechip the ecu for the mods and pick up Nissan Datascan it will help with the rom tune. Ohh welcome to the club.

maybe a RB25 turbo or something newer but I would focus too much on a turbo upgrade so soon where there are other important parts that sould come first.

That's still ceramic, those are slow and cheap, if you go over 14lbs they blow up.

Just remember, first off ball bearing is the only way, then; larger = more lag = more power when it spools up.

Have fun and enjoy the motor that should be in my car.

[bigk]

hoslet hy35 its cheap and good for 400 hp

[s14 2510's]

I got a hks 2510 with t3 flange for rb20. Im taking stock injectors out of my gtr and puting them in my rb20 with the drop resisters. The stock rb20 turbo is a turd. But it is nice to start the engine all stock first to make shure you are running correctly before you make upgrades. That way you know dont spend a week (F)ing aroung trying to find all the small problems when you go to tune for the new turbo ect.... Im looking for 300hp and the car is setup to drift. I just wanted a turbo that was not laggy when tuned.

[Kansei240sx]

Walnut sized turbos are the way to go if you drive a honda, im going to see what i can make with this stock GT28 of mine on the RB25. Then ill just toss it for a few hundred with all parts, and upgrade to a Holset turbine, with injectors, a powerFC, Lightwieght flywheel, clutch/pressure plate/ and Wideband 02.

Holsets are pretty badass for the money. Im probably going with the HC1

[rb240driftchik]

ok thanks for the details..but i already know everything im doin to the car..ive got lots lots lots in store..actually all already written down..and in waht order and all priced out and ****..trust me i did my research..all i need is suggestions on waht size turbo..i dont think im upgradin the turbo first..but def not last..so let me know what size TURBO you think..not all the other stuff...im good in that department..lol but thanks lol jk jk

HAHAHA how bout this turbo??...

DONT WORRY IM JUST KIDDIN lol

[rb240driftchik]

first off ball bearing is the only way

sorry

for most people the 500-800$ price increase and 2-400rpm spoon reduce is not worth the money.

it all depends on what your doing with the car where that extra RPM makes a difference. and remember, once the turbo is spooled, it stays spooled.

[Joe]

oh yea and rb240driftchik, welcome to NICO

but please, drop the "i know what im doing and i know what i want" attitude. you are 17 years old and some very intelligent people who have been around a littttle bit longer than you are giving you very good advice.

just put the engine in, then have fun. dont worry about huge upgrades till after you learn how to drive the car. Dont take anything personally, im just giving advice.

[rb240driftchik]

thanks i appreciate it..sorry that i have that attitude..i dont mean to..its just alot of the time guys talk to me like im retarded just cus im a girl..so i get really defensive..sorry ill stop! lol thanks for the advice :] lol

[Kansei240sx]

I dont drive a honda and never will, but i agree with Kamin in the highest reguards of what he said. Learn some more about the motor and how to properly drive a higher HP rwd car.

Going from a FWD acura/honda is a completely different ballgame with a turbo rwd configuration. When you hit 275 rwhp on a 240sx it starts getting crazy.

[krayton]

get an rb26

rb26 = drifting

[koukicody]

any rb= drifting

[Bronze MFP]

this thread hurts my brain. get the STOCK swap done first. if you get that running right and reliably you will have tons of fun. after that, think about mods. unless you just dont give a **** about reliablity, then jump in with a huge turbo (and supporting mods...)i've had my relativly stock swap for almost a year with no problems, and am still having tons of fun with it.

Welcome to NICO, Brantley! You'll find lots of help here. And don't worry, you're definitely not the only girl here. Ignore the leghumpers - you'll get used to them.

[the_momo]

welcome! dont worry about the guy girl thing, my gf thinks im retarted because shes a girl. at least thats my theory. also, weve seen you, but not the car in question. needing some pics of what you got. and you can feel better about yourself if your car isnt the factory ghey pinkle that my car is. thats what my lady calls it. pinkle....yay

[Carl H]

wow that pictuar is scary...some one had too much free time.

[nchopp]

Yeah, me, Matt, and Dan were bored a few weeks ago. This one's my particular favorite:





This one didn't work out as well as I wanted.



And, Matt.



Sorry for jacking the thread.

[skillzilla]

If you already have everything figured out, with how much it all costs and what order to buy it in and where to buy from, youre almost all the way done. Take that list, burn it, then pee on the ashes, and throw them in the trash. Then, take your current budget, double it, and hope for the best.

Now, if you want to swap in a basically stock motor and do some supporting mods, thats a whole different ball game. It becomes tiresome when everyones first post in the RB forum caters around what turbo to buy or needing directions to a wiring write-up.

Also, check out this page for more mod info, in case you havent seen it. It says +1 for the RB25 snail as a good initial upgrade, so take that with a grain of salt. Turbo talk is on page 3:

[Carl H]

hey if your current budget is 0 like most ppl wanting to swap a rb20 then you def cant double it and expect more :p

....Take that list, burn it, then pee on the ashes, and throw them in the trash. Then, take your current budget, double it, and hope for the best....

[Dano]

Welcome to NICO Brantley! Glad to have ya aboard

Carl is the resident RB20 guru, and Joe (Kamin) and Krayton know RB25s like the back of their hands, not to mention every1 else, your in the right place for info. Sizing a turbo requires many variables. What are your power goals/ budget/ what are you using the car for (auto-x/drag/raodcourse/ just street, etc)... once you know all that you can go from there... Based on that, you may need to change the size of the fuel system and other supporting mods...

[Chaos the Xile]

YEa we are not gonna steer you in the wrong direction when it comes to RB's these are our children, that we have put countless hours into for perfection!

If you put the motor in with just the basics - FMIC, Fuel Pump, BOV, Intake, Exhaust, Cooiling Fans - You have a pretty kick as car from jumpstreet, then mod from there. Its the easiest and safest way to go. Trust me I leanred the hard way when I was doing my RB20 swap, I should have listened to Carl, but I was eager and hot headed. Now I've learned to slow my role and time my time. That why I'm getting really great progress out of my RB25!

[CursedGTR]

Go big or go home HKS GT3040 Twin Kit. It is the bomb diggety.

Or you could take the smart way and make sure you have a functional vehicle before you modify it. A turbo isn't **** to change out, but a new motor is. I could care less either way and I am not in love with my suggestion but I have made quite a few costly mistakes that have ran me into the 10's of thousands over time.

[Dano]

OK... WE'VE ESTABLISHED SUPPORTING MODS AND PROPER SETUP ARE VERY IMPORTANT. She says she has it all planned out, regardless if she does or needs to make some changes depending on the turbo setup, she wants help sizing a turbo.

We need a little more info to better help you pick a turbo, as mentioned above, that way we can size it up to your application and needs
