Hey guys, thanks for the comments
No progress over the weekend, I drove the S70 for five hours down to Philly, an hour and a half to Newark, then drove a very floaty and numb A4 to a neighborhood 45min west of DC.. got about 18 hours of driving time in from friday night to sunday night, while the engine just sat in the garage at home
ETM is garbage.
+1 to that, I like my throttle cable. ETM has it's uses, but this project is not one of them
Should be a fun project. 
So you are just going to port the -98 intake mani to mate up with the larger ports? Too bad you didn't get the new intake mani with the motor, you could have cut the runners off and built a custom plenum.
No VVT on the intake? but you plan on keeping the exh VVT.. building a controller? What are you using to tune the motor? standalone? TT?
What is the difference in valve sizes with the new motors compared to the -98 T5s?
Thanks Mark
Your build is one of the ones that inspired me to embark on this process. How is your engine doing anyhow? Did you ever get it switched over to a single mass flywheel and turn up the boost a bit, or is the little one still taking up too much of your time?
You nailed it on the -98 intake, that's exactly what I plan to do. I'd love to fab up a custom intake manifold, but I'd be kidding myself if I thought I was skilled enough to pull it off properly. Maybe it's worth a shot anyway..
Noo VVT on the intake, afaik, only R engine and the 05+ T5 engines have dual VVT, the others got single, exhaust on the turbos, intake on the NA engines. It is my plan to build a VVT controller similar to what Lucky describes here:
http://volvospeed.co...48#entry1709248I haven't decided what input to use for modifying the exhaust cam timing, but I think I'll just stick with a MAP sensor feeding the circuit board...
For tuning, I'm planning on going with TT once the COP support is rolled out. If that implementation doesn't work out the way I would like, I'll go with a standalone setup, although I would really like to avoid that because I would like to be able to basically swap engines over a weekend and having it driving in a short time. Having the car sitting in the garage for a week while I figure out the wires isn't really something I want to do
Please correct me if mistaking but you talk about 143mm RSI rods while your engine comes with 147 mm rods.
The 143 mm rods are used with a 93.2 mm stroked crank. Unless the piston compression height is matched to the combination of a 90 mm stroke crank and 143 mm rods it is not going to fit.
Just a FYI. Good luck with the project.
Ah, thanks for the insight Johann! I'm always trying to find out more about these engines, and what the differences are between the different engines and what changes from year to year. I put together what I thought was a relatively accurate compilation of some info on these engines, but it's quite likely that I'm mistaken. If you don't mind adding your input and pointing out things that I could be wrong on..

For the rod/piston combination, I am under the impression that despite changes to the rod length through the years, the crank centerline to deck distance remains the same for all of the 2.3L engines. Since this is true, the 139.5mm rods and corresponding pistons that went into the earlier engines should work without a problem in the later blocks. When you look at RSI's catalog, they offer two rod+piston combinations for the 2.3L engines, 139.5mm + pistons with a 35.9mm compression height, and 143mm rods and pistons that have a 3.5mm shorter compression height, so that the whole package is the same height. The idea that this engine could have the 147mm rods was something I didn't even think about, since I thought those only went into the NA engines.
Either way, I'll know for sure once I pull the engine apart, which was the secondary goal of this project: to document as many things as I can about the engine for future reference. It make me sad to see how little real information there is available to enthusiast builders in the states, and I think that is a lot of what is hampering our development of these engines.. If I can do anything to help someone else do something better down the road, I'll be happy
Umm who s40 is that
What S40
wish you could make a S70 stroker moter... cause id stroke my S70, erotically
I could, but 90mm is already long enough.
This should be a good thread to watch 
.
It's always fun to watch a noob learn from his mistakes, isn't it?
