Ok so here is the steup. I am a guy on a budget ,git a awesome 7 year old and a good wife who who regulate my money often. But blew the stock turbo on my rb2o ( not ballin staus to some of the bigger more impressive setups on here but works for me) and i daily drive my 20 so......... :) Upgrades now i figured t3t4 to4e turbo with .50 housing mani upgrade and 550 injectors to start,but from there i am blank????????? So some suggestions would help me out.. Dont forget i am on a budget ,but all the help will go along way :yesnod hit me back.

Yeah Z32 maf, Nistune real time board or if u don't want to tune CarlH rom or who ever. FMIC, Use the stock exhaust manifold and cut a hole for the external gate save some money.

colder plugs like a 8 maybe colder depends on the boost ur ganna run for a dd and a tune is not really needed for a dd if the ecu will program itself butbor the higher u go ull notice ur be running lean or not enought boost ect. but most to4 r pretty much plug and play and for mani get a ebay special and have somone weld a 38mm external wastegate to that "easyer than the stock mani to weld to"

WTF language is that?


OP--I'm not sure what this dude is saying, but I think he is trying to convey you won't need a tune with a TO4e. Unless you want to drive around at like 5psi all day, you absolutely WILL need a tune.

if u knew anything about tuning u would know what i was talking about i am ASE certified tech at TurboMaster in San Marcos CA and i have three hks to4z and u can do a bolt on To4 an run 15psi and not touch a thing. the if ur looking for power then yes ull have to tune it. the ecu can learn just like a standalone can but tuning is to try to get the potential power out as opposed to actual power the thing hes ganna do r not drastic enough for a tune like ur think hes not bypassing a the maf or anything like that. hes doing BPU all the parts r bpu and wont need a tune to run as a DD

LOL, so I guess you don't need to graduate the 3rd grade to get that old ASE Certification then, eh? Wow man (*edit--I mean boy--I just say your age), your english is TERRIBLE :rotfl There are so many completely retarded things you just said in the last post (aside from your lack of understanding of the english language) I'm just going to pass. Have fun slapping those T04z's on your RB20 with a stock ECU and letting the ECU "learn" how to control things (I'm not even going to get in to using different injectors and MAFs) at wide open throttle just like stand alone ECU's (Power FC?) do :bowrofl:

How much of a "budget" are you on?

Because if you are that tight for money, just throw an RB25 turbo on it and call it a day. There will be no need for tuning with that turbo and you will get a noticeable boost from it as well.

If you are not on the kind of budget that I would be on in your situation then do something like this...

550cc injectors, walbro 255, adjustable FPR, t3/t4 that you want to use, Nistune board 2 depending on the model of your RB20, Z32 MAF (N62), 38mm wastegate if the .50 trim is not internally gated, FMIC, boost controller. Retain the stock manifold as others have said, it can save you quite a bit and you can have a wastegate flange welded to it if your turbo is not internally gated. You will also have to get a new turbo elbow, turbo to downpipe along with the fabrication of FMIC piping from the new turbo.

550cc injectors - 250/300ish$

Walbro 255 - 100$

Adjustable FPR - 100$

Nistune - 430$

N62 Maf - 60$

Boost controller - 100$

FMIC piping - 250/300ish$

FMIC - 150$

Turbo Elbow - 150ish$

Cost to get it tuned, just factor in 400$, that should be enough.

I'm just doing a rough estimate there obviously...this is just to give you a general idea of what you are getting yourself into. If you have all the funds in order and a fabricator lined up, I would project the car to be down just a month at most from the day you order the parts. Personally, if it was my DD, I would buy another car and build on the RB car once I had another daily.

I love when guys come into an automotive forum announcing that they are ASE certified mechanics like that demands instant credibility. v kush, you should be embarassed of what you just posted because, if you're not now, you'll look back on this post in 5 years and think "Man, I was an idiot!" :facepalm:

whoa nelly, idk if i wanan touch this one.... but since its a rb20 talk to carlh his chip tunes are god like, its cheap and effective, and if you on a budget i think rb20 exh mani os a t3 flange, i would talk to ricky at raw brokerage he now carries the hypergear turbo that are BOLT on and use existing piping, and wil probally last longer than another used oem turbo

everyone is acting like hes going for power but hes not looking to rev this piss out of it hes going for a good DD with a to4 btw u shouldnt run more than 12psi

if anyone wants to talk s*** pm dont do it on this guy forum everyone should know that

krazykouki - its a good build but its not a DD build its a good 500hp build if tuned right

LOL, the more you type that gibberish, the more you embarrass yourself. Aside from the content of what you are *attempting* to communicate, your posts are nonsensical jumbles of words with no rhyme or reason. My 5 year old cousin writes better than you do. I'm going to go ahead and TRY to translate your blather into english so we can all see what a f*** retard you are by both your lack of literacy AND the content of your ideas.

Wow, that was more difficult than I thought. Do you really speak like that in person? Your mom should be punched in the face for letting you grow up with out learning at least basic english communications skills. I'm sure you can probably tell her that for me tonight since you are probably still living at home with her :dblthumb:

^Fixed...or fixed the best way I could without misinterpreting anything.

How is it not a DD build? The list I made are things that he will HAVE to have in order to make his car perform correctly. If you do any less than that, you are asking for issues.

Also, if you want people to take you seriously, at least proof read what you are typing and people won't f*** with you. Also, I do not doubt your certifications but some of the things you are saying are not true. All because you got certified through ASE doesn't mean s***, you could pass the test's and still be a dumbass when it comes to performance oriented cars. There are plenty of people who daily drive their RB cars with larger turbo's running 18+ daily with supporting mods of course. Now, please refrain from talking about things that you appear to not know what you are talking about. I've been doing RB swaps since the days of Unstable Hybrids, Top Hat Performance and Axe, I can do this s*** in my sleep. My friend is the first one ever to have an RB swapped into an S chassis in the states, my other friend is the first ever to have a VH45DETT swapped into his 300zx..etc..etc..the list goes on. hell, I had my first RB swap back in 03.

VKush, I think what everyone is trying to say is that a stock ecu isn't going to recognize 550cc injectors and a larger MAFS the same way as stock injectors/mafs, hence the recommended tune. Of course you can put a bigger turbo on the motor, but other parts will be close to, or out of, efficiency.

Actually what I was saying is this dude has NO clue what he is talking about. He is lying about tuning and "managing" (what ever that means) most of the cars in what ever county in CA, and an ASE certification means about nothing, especially when it comes to RB's. Most people that have been wrenching on RB's and RB swaps for 5 years+ know more than your average 19yr old ASE certified mechanic that changes your oil and rotates your tires at the local dealership. He obviously has no understanding of how ECU's work and doesn't understand that a "to4 turbo" could be anything from a 300hp TO4b to a 700hp TO4z. Also, the difference of these two turbo's at 12psi is immense. He's a fresh out of High School kid who has read one too many TurboTuner magazines and needs to quit filling this board with s*** that will cause people to blow up their engines.

O yeah, and Ryan, turn on your PM's bro!! :wavey:

O yeah, and his sig under his avatar says something about 403hp, then he claims
i can get 370hp 278tq out of a STOCK motor
Well, if he's talking about rwhp (and with precise numbers like that he better be) and a RB25 that hasn't been opened up, big whoop. I made over 500rwhp like that. Now if he's talking about the stock turbo RB25 (and don't even get me started if he means RB20) he's lying through his teeth. Also, the pic in his sig has a greddy intake for an RB25 and has the bump for NVCS on the timing cover, so obviously this isn't a pic of what's going on underneath v_douche's hood.

LOL, sorry. If he would have taken his grammar beating and argued when everybody tried correcting his back tech info, I would have left it alone.

OP--just to add a little back in to this discussion, KrazyKouki's list is pretty spot on. I might add a clutch to that list, but everything else seems perfect--oh yeah, and I used to be a big fan of using FPR's (fuel pressure regulator) with after market fuel pumps, but after seeing a stock FPR hold back my twin walbro's with no problems, as long as your is in good shape, I think you can probably get away with out a FPR.

Getting all the supporting mods in place is the expensive part. Putting on a bigger turbo and tuning is cheap. If you are tight for money, an RB25 turbo might be the way to go. Keep in mind the RB20 injectors are pretty close to max anyways from the factory (relatively speaking) so something to tune with and keep an eye on injector duty cycle might be a good idea (does a SAFCII do that?)
