By the way you cant use any aftermarket dp. the bell mouth ones dont work. Here is the one I custom fabbed in 20 mins just to drive the car around. LOL
started as a helix catless dp and then cut the bell mouth off the factory ine and the usdm one. came out like this and fits like a glove. As you can see at the top there was about 3" of pipe added. And that sexy adaptor plate was made by the one and only Kplutien. It worked perfect. Mounted Thanks again Ken. Now get your hodge podge pile of cam bs together. Clearly seeing it doesnt work again.

It seems a large amount of people are spinning bearings , how many of you daily drive these setups ?
I am ideally looking for something that if maintained well can last me 50-80k miles at least. |

I've driven 10k on mine since the swap, and it is a DD. MY UOA came out flawless. Spinning bearings will most likely be the result wrong/low oil, cracked oil pickup tube, tracking, revving it high w/o proper warm up etc.
There is no reason why these motors shouldn't last 80-100k w/ proper maintenance. |

I am one of the spun bearing guys but I've read this complete thread at least 2 times complete and I couldn't count a handful and spun bearing issues. So I'd say this is 1% kinda issue like the government stuff, right? haha

Maybe I am just paranoid.
The motor swap really is something I want to do but I am debating just saving for an E36 M3 instead and daily driving the wagon forever. |

I also owe you d_Rodman for helping me figure out I had a ej207 when I found that gem on craigslist a few months back. I wasn't looking for one, but after doing the research on it and reading through this thread, I knew I wanted one.

I spun a bearing in my v6 207. It had 180,000KM on it and I was running 10-30 Royal Purple.
I blame myself I was driving at too many RPM for too long. EDIT: Thought I should add that I beat the crap out of it on a regular basis at the track and was running a tomei m7760 (20g) for it's last month Last edited by dundunskeert; 04-03-2013 at 10:07 AM. |

According to Sponaugle they are the same part number for the (later) JDM and USDM intake AVCS cam gears.
http://forums.nasioc.com/forums/show...5&postcount=47 That whole thread is an excellent read for understanding differences between the EJ205 and EJ207 cams and how AVCS works, etc... Last edited by Concillian; 04-03-2013 at 11:00 AM. |

Is Rotella 0W40 a good oil to use in a Version 8 motor?

+1 on Rotella T6
If you want a lighter weight, I had good luck with Rotella 5w40 in my EJ207 & built EJ257. Thanks! Quote:

The usdm cam gear will not give you more than 30 deg of advance, it is physically limited by its design. Based on this I would assume they are not the same part, however it appears they are the same part number. The jdm cars do 40+ deg from the factory, and from the ej207 swaps we have put into 32bit cars they have no issue hitting 40 deg of advance so the 30deg limit on the usdm cars is a physical limit on the 255/257 motor cam gears themselves.
Can someone find the same picture of a jdm cam gear that I can measure digitally. Edit: further digging I find this, question is why are we able to get more advance from the jdm motor if the gears appear the same? The mystery continues....... Last edited by lukeskywrx; 04-03-2013 at 02:58 PM. |

based on indirect reference through the opposedforces catalog they are the same part number as used in the USDM Sti, however as a disclaimer,it is the Euro 2000CC DOHC H-POWER TURBO STi, listed for comparison.
Just playing devils advocate based on lukeskywrx's physical findings on the usdm cam gear,.. are the euro 2L Sti, equipped with 'doo-doo' cam gears just as they have small port heads? |

i know that in the RomRaider avcs tables, the stock tables go up to 45*, but in my logging, i've only seen up to 40*. no hard measurements here, just logging numbers, fwiw.

40 degrees is in terms of the crank. since there is a 2:1 ratio, it only takes 20 at the cams to result in 40 degrees relative to crank position. Just like how each cam gear tooth is 7.5 degrees of cam, but 15 in terms of the actual cycle. It's all explained in that thread.
The reason the JDM cars can have more advance is in the cams and heads. They run lower lift and the big ports bring the flow. The small ports require higher lift to get flow, so there's less cam advance available for a given valve to piston clearance, therefore lower AVCS advance in the USDM programming. 08+ Dual AVCS brings back 40ish degrees of overlap at low RPMs by adjusting the intake forward and the exhaust backwards. I've programmed and logged 45 degrees, and I've definitely seen a difference from 40 degrees at <3000 RPM as a result. Last edited by Concillian; 04-03-2013 at 03:40 PM. |
