i am Garry is building me a RB30 bottom end.....then i am putting it together here in canada, we have no experience in tuning RB30, so i would liek u guys help !!

what sorta thing should i look out for ?

what's the difference in tuning compare to RB26 ?

what computer is the best for tuning RB30 ?

what sorta things should we look out for when putting it together with rb26 head, i think we got the basic RB30-26 swap down..but there might be little details that we missed

the engine is going to sit taller, will it clear the hood, i know with rb26 and my t78 turbo it almost hits the hood, will i have even a bigger problem with this issue ?

anything other rb26/30 to BNR32 info would be a great help to us !!

thanks again !

if it was me (which it's not)

apexi powerfc

then if that wasn't available

autronic or motec

but that all depends on what tuners are in your area, whats the point of a moetc if no one locally can tune it ?

  • 2 weeks later...

any decent ecu will work as good as any it all depends on the tuner.

you can have the best of the best motec ecu, but it will be no better then the power fc or what ever if you dont have anyone that knows how to use it to its full potential.

if i was you find a really good local tuner and use what ever they recommend.

hi

thanks for everyone's replay

i understand that a good tuner beats a good computer !

and i also understand that not every computer works good with every engine set up

so my question is what computer works the best with RB30/26 with single turbo and no MAF

thanks ...

but thanks everyone for replying it really helped alot !

It sounds like your building a bit of an animal and cost comes second.

If you want the best, get a Motec ecu that is suitable for your engine.

Sure you pay a little more for them, but you are getting the best, used in all kinds of world motorsport engines.

what ecu's can your tuner tune?

basicly my tuner said, they do not reccomend Power FC......and told me to go for Raytec..but i called tomei and they said, since the Raytec is still very new, tuning RB30 with Raytec is not recomened, i have HKS f-con V-pro right now. but no one can tune it !! :dry:

motec is just too expensive and same as Haltec..

help

your tuner does not recommend powerfc....is he an auto mechanic, or a mower mechanic by any chance?? (personal joke, mate of mine is a mower mech and doesnt like powerfcs, works as a mechanic now. haha thought there might be someone else like him around canadia.) didnt mean to be an insult, my apologies.

Powerfc has got to be one of the cheapest, and easiest a/m computers to use. Its excellent value, and im sure almost everyone on here would agree with that.

Power Fc is good for your average modified street car, good for cold starts and cruise etc, not the choice for a race car which it sounds like you are building, thats why most people on this forum use Power FC. Only a handful have race cars, mainly street cars. I have used Power FC, Microtech, Haltech, EMS in customers cars, different applications for each one but all have there pros & cons. Apexi D-Jetro may be the go as it uses MAP sensors over airflow meters but is a shit too tune. I am building a similar engine, RB30/26, HKS T51R etc and am definately going to run an Autronic ECU. Much more flexibility for tuner and gives you the ability to trim individual injectors to get afr's perfect in each cylinder with the aid of EGT's. Its a set and forget deal. This is the heart of the operation, rather spend a few extra dollars here than risk the engine. Youl find that alot of the time on this forum people will advise on the cheapest rather than what works better, alot are only speaking from there own experience as they have ony owned a car with the one ECU or boost controller, ie $22 bleed valves etc. You get what you pay for. In the end your tuner is the person you should listen too. best of luck.

Well ill know soon enough, we will be using powerfc pro in the 25/30 in a few weeks when it gets tuned. So i guess that will tell the story.

He also mentioned that motec and haltec are too exxy for him, how is an autronic compared to say a motec in price? I thought autronic were not too far off a motec?

Edited by r33_racer

ive used EMS and microtec i would recommend both for the 26/30, if you where in oz i would say go for the microtec because with my experiance there is more people who know how to tune them well compared to EMS. they are both well priced (around $1500au)

i dont know alot about powerfc but the tuners i know dont recommend them so i didnt use it.

but all these ecu's are useless if your tuner cant use them, so i say use what he recommends or find a tuner who can tune microtec(or whatever)

They are not cheap but are getting more computer for your dollar. Have to compare apples with apples.

But if he is worried about price of Haltech, it might be too expensive.

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
