Skyactiv Remote Turbo Build

[Srad600]

Looks like you're getting there. I've been reading up on some recent Turbo tech and came across this Volvo "innovation" to reduce/eliminate turbo lag. It's pretty cool, they are using an air compressor + air tank to spool up the turbo and reduce/eliminate the lag. I'd imagine you won't want to go this deep but still a couple of links for giggles:

Pretty cool tech coming down the pipeline.

I read about the other day. It was posted on the m3r facebook page. looks cool

Well need 2 more 2.5" 90 degree bends as seen in the picture and will be ordering from china gain.. $10 shipped ea for the SS 304 compared to $20 ea

Awesome to see someone doing some serious DIY modding to a CX-5 AND DOCUMENTING IT!

Excellent read and thread, definitely subbing to this and looking forward to the next update. (2thumbs)

Damn. Yea ovt is projecting about 250 i think it was for their sky 2.0 turbo kit

 

[Chris_Top_Her]

installed oem drain pan modified with an an-10 fitting for turbo return, installed an oil sandwich plate, and installed glowshift oil P and vacuum/boost gauge

 

[Chris_Top_Her]

Alright oil sandwhich and pan wasn't leaking so installed my jbr catch can.. if you have awd you will have to improvise including using a different mounting location. Also the 3/8 hose is too small for the pcv valve and the manifold port so i ended up using some pf the 5/8 cut with the 3/ stuck inside of it for the bottom, and stuck the 3/8 into the oem pcv hose for the pcv valve #awdproblems

Hi if anyone is tapping a variable vacuum source for whatever reason , use this one, behind the tb. No oil vapor (the one above it gets oil vap). Before I tapped right off the pump and it was contantly 20in hg.

463gt was asking about balance shaft. wasn't about to take the cover off and make a fat mess sorry

crank

^^ Thanks for taking the time to take pictures and post them ! (drinks) What is the second picture? I can see a pice of the what looks like the crank at the top left...

The balance shaft looks different than the mazda 2.3 motor’s BS from the pics posted at JBR BSD kit. Its much more massive. I wonder if deleting them is still as simple as unbolting and they just drop out . Also if the same 2.3 BSD kit can be used to plug the BS oil feed hole?

Any one have the 2.5 FSM ? I have the 2.0 FSM but that doesnt show the balance shafts.

Holy crap, that thing is massive!

It's hard to tell from the photo but it looks like the 2.5L engine might be mounted higher in the engine bay (vs. 2.0L) to accommodate the balance shaft assembly?

Now do you understand why I want to get rid of it?

The 2003 Nissan Sentra SE-R Spec V Balance Shaft was a little smaller than this. More like the 2.3 BS but there was a lot of resistance than expected when spinning it by hand. So this might be same or more I would imagine. The Sentra Gained 5-6 MPG’s just city driving. The motor is spending more energy with the BS than without. Imagine driving on a flat road (BS removed) vs a road with 10* incline or maybe more (BS installed). I’m pretty confident it will be the same if not better results with the Skyactiv-G 2.5 . The vibration was ever so slight starting from 3.5k rpms and up.

Chris , any more updates ? Did you finally finish the install and started the tuning?

I am still building the exhaust. I just welded this. It will be coming off the hotside/exhaust of the turboh. It's upside down in the picture but the 180 degree bend will be the pipe leading to the left exhaust exit (looking from the rear)and the unfinished side will be sized according ly and a 90 degree leading to the exhaust cutout with a tip on it. The problem now is difficulty in getting precision cuts on the tube with what I have for welding, and since any gap will make a the arc welder a plasma cutter it's easier if I can put the pipe inside when welding. that assembly will have the exhaust hangers on it. I should be able to get one on the Y pipe, and 2 on the long pipe that will be there. I'll probably figure out a way to use the driver side hanger , probably for the charge intake. I also removed the ultra racing rear lower bar for more ground clearance for the turbo.

Depending on how everything works I may change later to a smaller profile turbo such as this one, but it would require minor changed since the turbo is situated differently.

Hmmm... should work. What could possibly go wrong? (shrug)

 

[Chris_Top_Her]

Did some more work on the exhaust, still need to clean off the swAg, and check for holes. Vertical pipe will be the exit for the passenger side exhaust, it's angled in towards the other pipe a bit, so I will need to angle grind it a tad and or use a inside sleeve when I add the few inches of pipe that I will put the tip on. I will most likely be attaching an exhaust hanger to the vertical pipe, or the pipe that will run just off of it.

What kind of welder are you using? Some of those welds look rough haha.

 

[Chris_Top_Her]

It's a smaw and it has a sharp learning curve. Also i only can weld on max or min, no in between settings
