Tomei 2.8Non cooling channel. Had 2 thou clearances the last engine and never had issues.
Top ring is Ti coated. (last engine had a standard Tomei top ring).
I have the "flex fuel setup". So when I'm belting it, it will have E85 in it. On the street it will have anything between E85 and PULP.
Same rear housing, turbine wheel and comp cover. There is 1.1 mm difference in the comp wheel, the 2530 being the larger of the two.
See if Elrodeo666 gets in here and tells you what HKS said themselves about these two.
I was having a few issues with this flicking off PS belt thingo. We made sure everything was "square", IE the PS pump/bracket was spot on and I also fitted the idler pulley thing for the belt. Problem went away. Car will be back on the road soon so I'll be able to report back.
Oh there will be graphs, when I don't know. After being off the road for so long I want to enjoy it for a while. I'll cant help to think I've gone a bee's dick big. There will be a 6262 thrown on and tried too at some point.
A little update.
Got the engine back on Friday arvo. Can't get some of the pics to work. Stupid things.
Manifold to gasket size.
Exhaust port to gasket.
Another picture.
Turbo's are almost done. Just need to do the drains and the top lines. I stopped because the sun was burning me! haha
The RP "modified actuators" work, it'll be interesting to see them as they are and with a controller turned on. Is there any difference? Watch this space
