GDZ1LA Posted April 28, 2007 Share Posted April 28, 2007 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..

sh@un Posted April 28, 2007 Share Posted April 28, 2007 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?)

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? 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..

R31Nismoid Posted April 29, 2007 Share Posted April 29, 2007 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.
