RB335

I have recently used Wren One Pty LTD, who is a wrecker in Perth that often gets Skyline, Evo, and lot of other JDM parts

That sucks did you end up getting it back. I'm wondering how was it stolen did someone break into a home or steal the keys off you?

LS39 = r34 gtr 3.54

RB25 NEO AWD engines use a different bolt pattern on the sump than other AWD RB engines, the spacing and angle between two bolt holes near the input shaft area differ, measure them if looking at second hand sumps to ensure same as yours The input shaft flange looks as if it might be a different length too ?, unsure about this.

RB26 worked head Removed from good running car to go larger engine. It has : - Intake, exhaust and chambers ported by RAMS - Supertech +1mm Valves - Tomei bronze guides - Tomei cam studs - Kelford Beehive springs - Titanium retainers Great for high HP street car $5000. Location, Perth, can send anywhere

Used Ben at J-Spec, service was mostly good and I did appreciate him being honest about cars condition and he did mention his opinion on cars that are not good enough to import even though I had a chance to get things over and done with so I did appreciate his advice on advising I wait for the right car to come by. I do feel there is a smaller but significant element of - hey if things go good, cool. If not oh well who cares get on with it.

I do have a spare set of coolant/oil lines suit EFR 1.05 rear mounting on 6boost if anyone wants, Also downpipe suit EFR on Skyline w 6boost.

What size dump pipe did you have before the 4" , or hard to compare what dump did as you also upgraded exhaust?

Doesn't the 9180 make it's max flow at 116k RPM wheel speed? I see most people here ended up not running the 9180 turbo this fast? I made similar power on a 9180 with a 1.05 as others on a reasonable reading dyno maybe the rear housing needs to go bigger

I'm also after a 1.45 suit a EFR9180 / 9280 if anyone has

My engine builder builds many high power track RB's, lots of dollars in the head, when I asked about the rear coolant drain he talked me out of it, so just doing oil drain only. My previous experience with PRP is the bloke who runs it likes to sell all sorts of stuff and talk you into all sorts of stuff whether it benefits you, or whether it doesn't benefit you.

Why are they made to work with reverse rotation? Is it a more efficient way to run a turbo?

There is also a N1 version of that hose if a recall, unsure of differences or upgrade

Check your engine mounts are good, too much movement may not be good for hoses.

Had twin Tial MV-S 38mm gates with Y pipe plumbed back into a 3.5" dump EFR9180 held power fine 8474 began dying up top, I had limited time to do more dyno runs so only did one test but quite a bit of street driving on both turbos. OK no problem i will try vent them to atmosphere next time see how it effects it will have much more sensors all over the engine on next motor too for monitoring stuff on manifold. I have no access to an engine or dyno at the moment Mafia you are interested i can send you my 9180 then cover freight back to me you can test it lots of tech talk etc but test ok.
