Yea, I'm going to do a remote set up. Thanks
, I had never heard of that until you mentioned it. Seems way more viable, cost effective (no turbo manifold needed) and safe (lower temp and low boost anyway) for this engine.
C&p from my pos ton mz247 I made today.
A remote turbo set up is one in which the turbocharger is mounted somewhere down the exhaust stream, rather than on the exhaust manifold. Some benefits that are attractive to me:
No turbo manifold is needed - I found that even though there is space behind the engine for a turbo (specially with a shorter manifold), no one has a head flange for the 2.5 sky and you'd be paying to have a one off manifold built (unless you build your own). Even still, it's a cramped space and most turbos will be too large to get behind the engine without partial disassembly; a hassle. Also frees up the engine bay of pipes bent everywhere. A big $$$ saver either way.
Cooler air charge - Because the turbo is further down the exhaust stream, turbo temperatures are lower (up to 500f on some applications) meaning less wear on the turbo/oil, greater effectiveness of the intercooler, all around lower temperatures and better tuning potential.
Some people complain about turbo lag on remotes, some don't (but then again people get turbo lag with a front mount turbo too). I dont give a shit about a half a second of turbo lag I give a shit that I'm getting boost lol. The oil line will need to be run further with the addition of a scavenger pump for return; not a big deal for the cx-5 as the transmission tunnel/space above the underbody panels provides plenty of routing space or space for a self contained oil system for the turbo (that will clear the yoke for the rear diff). The space on the rear axle is ample thanks to it being designed to accommodate a hitch.
Ovtune offers boost tuning and the only part that will need to be upgraded on the block is the OEM map sensor. It caps and 1.8 PSI so a better one is needed. An oem Mazdaspeed or bosch type will work just fine. Actually corksport just released and 3 bar sensor.
Basically since the majority of the work on this just exhaust style piping, with the exception of the oil return or self contained oil, once I find a shop that will give me a good price on sizing and welding up the tubing I should be good to go. It will have to move quickly from there then I will pay for boost tuning (my tune right now is only for NA) from OVtuned (or drive with the WG fully open/charger disconnected or no exhaust until I get a tune lol. I don't believe I will need a large IC, the front of the cx-5 is already sized for an intercooler (diesel)I and If I wanted I may be able to fir a small one under the rear bumper.
You might be better off squeezing a td04h in there from a subaru. They are plentiful and easy to come by.
Yea, if physical size becomes an issue that would be a good alternative. I paid $175 for this one, I'm sure I can resell it for 125 or trade it for something like an IC.
I found some 04's for less than $ 200, one is designed more standard type, cx-7 direct replacement http://www.ebay.com/itm/K04-1-8T-1-8...624451&vxp=mtr
and another one is for an audi replacement, but it has a slim design where it doesn't bulge much.. that would actually be ideal for this type of installation. http://www.ebay.com/itm/96-03-A4-PAS...c82a74&vxp=mtr
