im about to start a high hp 30 motor. i know most of the things require but have i missed any out and what weakness are there at 700-800hp.. i dont want to do anythin thats not realy vital but any suggestiong would be great

30e block..30e crank will need big end grinding..

carrillo rods,, wisco pistions (good coice?)

std gtr oil pump ?ok?

knife endged and balanced crank (inc flywheel & power enterprice pully)

and thats pretty much what def will be getting done..

will be for dyno runs only at high power.. and maybe drag at lower power levels,

things im not sure about are (to save on build costs)

o ring block? or any extra block strengthing.

trust oilers on main bearing trust?

head studs? main studs? vs std gtr ones.

any heat treating/coatings?

26 mains and grinding channel in 30e block?

oil squirter fitting?

or any think else i have missed?

i dont want to do anythin thats not realy vital but any suggestiong would be great. ps that 30 post is far to big and its full of crap most and cant sniff out important info..

carrillo rods,, wisco pistions (good coice?)

std gtr oil pump ?ok?No, at least an N! pump with crank collar

knife endged and balanced crank (inc flywheel & power enterprice pully) I also got the crank cryogenically treated

and thats pretty much what def will be getting done..

will be for dyno runs only at high power.. and maybe drag at lower power levels,

things im not sure about are (to save on build costs)

o ring block? or any extra block strengthing.Not needed

trust oilers on main bearing trust????

head studs? main studs? vs std gtr ones. Yep, ARP do these, retap block to take Rb26 head studs

any heat treating/coatings?Recommend getting pistons coated

26 mains and grinding channel in 30e block?????

oil squirter fitting?Good idea, but aparently very difficult to do(about to find out)

or any think else i have missed?

its because the info is so bitsy its spread out on the sticky and most people arent actually answering the questions just talkin shit.. kinda like now.. if you canno help be please dont bother posting... anf you rite.. i dont have 3 weeks either.. i would rip my hair out before then im already since of the smack talk on there..

For a 'reliable' 700-800hp, everything will need to be modified or changed, particularly the valve train and head porting (you are using the SOHC 12V head, yeah?)

what is everthink..?? what have i missed mentioning

im using nothing less than a rb26 head jun intake 85mm throttle medium porting and mild apexi cams & pullies.. im more consorned about the strength mods not the head mods.. i know my head and turbo setup can make the power.. i just want it to hold down below..

can anyone helpme on some of these things..

whats required and whats not or any others i have missed

Edited by GDZ1LA

i just built mine to handle 700rwhp tops

basically need everything done yes.... pm me for more info, i could try send ya a list of my mods, theres just way too many here to list

get 1/2 inch head studs, block studs, if u can get the turbo, mani and dump coated then do that, i use a trust oil pump, was using gtr oil pump before but definatley dont want to risk it.....

ben...

GDZ1LA - Please read the RB30 sticky and also search.

There is more than enough info on what your asking about this forum.

People cant be expected to answer/repeat themselves time and time again.

If you do truly want to build a 700-800hp motor, then taking the time to read a detailed thread should be the least of your issues.

Rushing into a build is what will be the sad end to it.

Thanks

    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
