Gts4RB30

have of today after pressure test and measurements decided to go forged rods and pistons. pistons starting to micro fracture and rods are slighty bent.

i don't need to search for information i have what i believe to be most of it, what i'm talking about is the more refined things that i have yet to find and read. I'm not trying to "reinvent the wheel" i'm just putting smoother rubber on it. it's more so a guide that will help people who don't know, do more at home and be able to go to the machinist and engine builders and KNOW what they want done with out all the dilemma of not know about the smaller refined issue like decking, cr, acid bathing and tolerances etc etc. what kind of knowledge and information did some of us know 5, 10 ,15 yrs ago that we would of like to of known today.

CLEARLY.

spending money in the right places can never be over kill. as long as you have the right supporting hardware you can be sure to maintain comfort and trust in pushing your equipment to the edge and for it to be able to give to you what you ask. with the rb a well knowen engine for destroying oil pump it's only fair that i use one that will be able to do the job right the first time!

yet to find what i will be talking about.

Good evening everyone My name Is Rob so instead of typing Gts4RB30 Just use Rob. Tomorrow i start an in depth guide to building an "rb30det" as from what i have seen and read, there are just a few little things that are missing that are very important. Albeit that one of the members on here as done a very good job and a very well thought out guide it is still missing vital information that is needed before you walk into a workshop and say i want this whats it going to cost and can i short cut this and that. Yes some people on here have done things there own way and have been successful, what i am going to be writing has nothing to do with their builds nor put them down. it will be, for all intensive purposes,a "guide" or "form" of information. Some of it will be shortened as it has been covered MANY times and some will go into depth as to how and why things need to be done. I do ask however that people with professional experience and people with in depth knowledge also please interject with your information as i feel the more the better. IDIOTS please refrain from being yourselves and shooting your mouths off this is not a political discussion or bitch fest so leave it as they say "at the door". Moderators if there is any issues with this topic i ask that you communicate with me via pm as any issues with me being "OP" vs moderators i wish to keep personal and professional. The information contained in this guide will also come from other workshops as well, however in saying that if you are a company director, manager, head mechanic and do not wish to be mentioned once again please contact me via pm. So before i get started, thank you for your information, help and support. The engine being built has the following going into it. 1992 R32 GTS25 Rb25e head upgraded valve springs tomei poncams full head service. 1987 VL Commodore Auto RB30e Engine - (9.0:1 Compression Ratio) bore (maybe) hone balance standard rods standard pistons acl racing bearings both big and main hastings rings Nitto oil pump with crank collar Drill and tap new tensioner pully new welsh plugs New water pump AWD Adapter plate and pickup. Tonight i will finish it here as i am tired will edit this tomorrow with more information.
