Hello everyone,


I had asked this question in the "ask the Camaro team" forum but got no replies. I want to put it on here too so that i can see what you all think. I know that in here compared to the Camaro team forum we probably wont get the actual reasons why. But i'm ok with people taking their best, educated guess.

So in the past i've messed with hondas both n/a and aftermarket turbos. My experience was with B and H series but i did a bit of researching on the D series engines too. Also at one point i was thinking about getting a 240SX and swapping in a SR20DET but i didnt do it so most of what i know is just research. On those engines things like the water pipe, oil filter and i think alternator and starter were on the intake side. I think the Mustang Ecoboost is the same way too?


I was wondering though why is the LTG designed with the oil filter and water pipe under or near the turbo manifold? was this for ease of production? or a deliberate design decision? did the engine used to be n/a and later converted to turbo? What i'm also wondering is will this design end up getting in the way of people who want to run aftermarket cast manifolds with larger turbos or aftermarket log style turbo manifolds with larger turbos? should the proximity of those accessories (water pipe, oil filter, other stuff) to the turbine and downpipe be a cause for concern for people wanting to modify their cars? (ie clearance issues or heat related issues) or was aftermarket modding not really a consideration at all?


Also what other turbo cars/engines out there, preferably I-4 or I-6 have the same kind of engine layout as the LTG with accessories on the exhaust side? can be longitudinal or transverse, fwd/awd/rwd doesnt matter.

Far as I know from GM vehicles I've worked on (some suzuki vehicle engines are the same) they have been putting the spin on filters by the exhaust manifold for years now. I dont have an answer why they do it, but some of them are a pain in the butt to remove (try a suzuki XL7 aka chevy equinox v6 or gmc acadia).
I personally think engineers design it to help with getting the oil temp up faster since exhaust manifolds get up to 600 degrees. It's either for that or their trying to make it to where the average person cannot perform any service and have to bring it in to a dealership (marketing tactic). Wish I really knew as well cause it's not too funny to burn your hands just from trying to get to it.
Other LTG engines used are the cadillac ats, malibu 2.0T
