Guilt-Toy

I do regret building my RB30DET. I should have stuck with a stocker with 300rwkw and just lived with the less power. or gone for a RB26 The reason why i say this is because the RB30DET is a major pain in the ass, sure they make good power.. i will quote the last guy i took for a drive who is into v8's "ass raping power". But in the long run I would not suggest to anyone to build a RB30DET engine unless. Your current RB25DET has blown up, leg out of bed and needs to be replaced and your head survived. You got shitloads of money and you want to build a monster You really need the extra torque and dont mind losing revs You dont mind having a less reliable engine. You dont mind going through oil controll issues, which are a major pain on the RB30DET If the above seems okay to you then go for it. remember the following when doing your RB30DET. Follow sydney kids oil controll guide to a T. do not miss out on anything especially for a drift car thats going to be reving alot, your going to get soo much oil in the head you will be squirting oil out of the breathers and i cant tell you how much of a pain in the ass fighting that problem is. Get the crank collar and MAKE SURE the engine builder who fits it trims the front to match the crank!!!! THIS piece of advice cost me a $1300 engine in out job for a replacement crank and NO ONE wanted to take responsibility for their f**k ups. It wore the back plate behind the timing gear and eventually lost 40 thou on the crank bolt and it came lose and flogged out the keyways on the crank, had to buy a new collar and crank and bearings etc etc. Standard RB30e pistons will be fine, make sure you use ACL race series bearings or king bearings or nismo Use ARP rod bolts on the standard rods, dont bother treating the rods for anything under 300rwkw Install a GOOD oil catch can system... and i hope you got a rb25det gearbox and a good clutch. expect to break things because these engines are tuff. Ive had my rb30det since 2003 2004 ??? and ive been through everything during the whole learning process, it might not be such a big pain in the ass for you as it was for me but when i think about it now, i would never do it again. I would get a RB26 and push that. Hope this helps, if you do convert then welcome to the club, this engines put a smile on anyone's face that i take for a drive, some people scream at me.

yeah i know about the AFM voltage correction... I guess i need to jump on the dyno again before doing anymore testing as its too hard on the street and i need to get my turbo rebuilt before i do any of this. I need to re-test it because i think its going wayyy past 5volts

Can you help me with a table i can try ? I am using the standard rb25det ramp table with my car, and its got the rb30det. i noticed the last ramp table is 21321 can i increase that number to get a little more out of it ? or do i have to just decrease the AFM correction ? I am only reving it to 7000rpm if that helps and i find with the standard ramp table it goes all the way down to line 20 on 25psi on rev point 10 then across 3, then up one line and across 2 then up another line and across 3. So it maxes out all the way down but then comes back into the map. any ideas? ive got datalogit so i can send you my data file?

should nearly do a low 12 with that power

you should just buy a Plazmaman plenum for it.

no prizes this year ? whats the point of winning if you get nothing out of it ahhhh well my turbo shat itself, going for a rebuild so it should be ready to make an appearance if i still have enough $$ left over... rebuild gt3540 = $1000

im going through the Q45 AFM debarcle as well at the moment. Mine goes down to line 16 on 9psi!!! on 24psi its well and truley on the last load point Is there anything i can do to help sort this crap out ? I got 363rwkw but it was well and truley maxed out, does the Q45 go to 5.2 volts or 5 volt? Cheers

I want to swap for my .82 PM me and i will give you my details.

Thanks for your help Blitz. What do you know ? it sold. Good luck finding your $1200 fakies guys, someone got their hands on a perfectly good order working RB25DET ecu and you all missed out crying about the price. SOLD!!!

Item:Z32 AFM's Age:1 month old Condition:As New still in BOX's Price:$320+ post EACH (not neg on this one) To Fit: GTR & GTST or whatever (What car) Location:Newcastle Contact:This thread please, unless your going to buy them. Comments:These units were put on a R32 GTR and run over the holidays, the GTR now has a jetro ECU so these are not needed anymore. They are in new condition and work fine. They are BOSCHE units with TOMEI plugs.

the grand champion should get a special sticker

was that power figure before or after the head job ? Will any manifolds & coil packs be available as well? wouldnt mind swapping my 25 head to a 26 head. Why are you selling ?

quick sale... $1400+ post or PM me close offer. Anyone? this will be going on ebay soon, and will sell on there for sure.

No

those gtr's probly get rebuilt after every race.

I would offer $300, your asking way too much.

No.

id go for the localised products

Everything is for sale for a price, will seperate h/c for $500

thats a good AFR too! nice tune there

anyone have any ideas? I am lost.

I am not interested in PM's asking me whats the best price i will sell for, this item is hard to get now and this one is in good working condition. If you have a offer post it on this thread, stop sending me PM's and DONT WASTE MY TIME. Someone who wants this item will buy it because they know what its worth, i am well known on the forums, so you know its not a scam. Thanks for the interest but please post it in this thread, will update post.

I was thinking the same thing, why the hell would they want to read 3:1 AFR ? the sensor wont even read that low !!! Anyways i like to run the engine rich, 11.6:1 has kept my engine alive on 25psi so thats where its going to stay. Just seems like the guys in sydney like to run em really lean or something, maybe they get paid more money and can afford a couple of rebuilds a year ?? or they want their customers to come back in for engine rebuilds soon after ?? More blown up engines = more engine work needed LOL *shrug*
