What a complete piece of crap! can it get anymore ghetto looking?

Will it even hold up to a 2 mile test drive without falling apart.

that piece of turd may hold up, but why in the **** is that thing in the trunk?
Isn't the whole point of rear mount to save space, and you got plenty under the trunk...

breathing in your exhaust leaks sure does cause you to make bad decisions.

so true.....and think of the heat that thing will be generating into your trunk not to mention the gas tank is not too far away.....overall a retarded idea

no airflow = great heat = more iefficiency

i dont know about rear mounts, but subaru mounts their turbos at least 30" from the cylinder head, and so does porsche to a lesser extent.

Granted this is because of the packaging disadvantage these cars have, but what if the turbo is mounted just before the stock cat location in the miata? I'm sure a tiny KKK off a VW 1.8T or similar would fit there, and spool pretty well too. This would bring down the cost of the whole system, for example the manifold and downpipe wouldn't be needed. Of course, you'd still have to deal with problems like oil scavenging. The oil inlet and water lines wouldn't be an issue other than being freakishly longer than normal.

but at the same time, there's plenty of room next to the engine, without the need of pumps and bracketry and this and that.

Definitely, but I'm just thinking about the cost aspect of it. That's nearly $500 saved in parts alone for someone who's on a really tight budget. I'd have done it if I hadn't been this deep into my build. Even at the risk of getting ridiculed and laughed at.

I'f I had to rig it that bad, I'd rather not Turbo at all.

wow... that is hideous. Its not the greatest layout for a miata.

haha i like that lsx comment. Ive sat in some of my classes daydreaming about just building an insane LSx miata with twin turboes mounted in the rear. I mean why not? ...




dont answer that

The only good part about that rear mount in the trunk is you can fab a grill screen and to while tailgaiting after a good boosted run.

Would be pretty nice to have some steaks ready after a good mountain run.

Umm, this is a 996-up turbo header. Really doesn't get better than that (the basics of 3 short runners, not the specifics of this design):

I've thought about the K03, because people take them off all the time. It spools off idle, but it runs out of flow and torque drops off rapidly after about 4800 rpm on a 1.8L. Even on a 1.6L, it would be small.

I think a WRX turbo would be a better choice, as it's nice and small and is frequently upgraded.

:lol: man are you serius? I will give you props for asking intelegnetly but as my buds have said and shown a rearmount turbo is one of those if you can and wan to then do type things. There is so much room in our engine bays it isn't even funny man, turbos do not take up alot of room. And ceramic caoting is a great way to keep temps down. GL I hope you survive the initial hazzing cause you actualy seem intelegent. Just not knowledgable.

well that mainly becuase they you an "H" block instead of the traditional inline 4, hell turbo subarus still have "headers" along with the turbo

Mounting a turbo 10" from the head, and mounting it 30" from the head has different demands made on the turbine. In the latter case, significant amount of heat would have been lost from the gas by the time it reaches the turbine, hence a smaller turbine would be required to achieve the same response. That's why I said K03, not the TD04 which is big enough to be mounted in the regular position.

the turbo being mounted where it is on a subaru doesnt have much to do with anything more than space...the place it sits pretty much is THE ONLY place you can mount it, and THE CLOSEST that they could get that sucker to the actual exhaust ports in heads.

take a look at my engine bay during turbo swap:

there is BARELY any room in there as is


now dont quote me on this, but i think the long header piping actually has something to do with subaru's generally having more torque than say evo's, while the evo's turbo sits mere inches away from teh engine, it holds boost all the way up top and usually has a little bit less torque and more peak power. on a subaru, even with a large turbo, the power usually peaks a bit before the redline and usually boost starts to taper, even using a large turbo and a mbc, it still tapers up top. so they usually have a SHITLOAD of torque come on in the midrange, and then start to die off towards the top....im assuming a rear mounted turbo kit would have more lag than normal, then have a ton of torque, and start to taper off up top pretty steep....which is kinda dumb: no lowend, no topend, just a mild push of torque exactly in the middle where its not here nor there....

feel free to correct me if im wrong.....i am merely speculating

J.T.

Truth, where else do you want them to put it? Only way to place it closer to the exhaust ports would limit you to putting it in the crankcase or the oil pan

well they COULD raise the engine a bit and fit some small *** turbo in there, but that would be dumb as hell, not to mention kill the cars cornering/performance

J.T.

Then they'd also have to run a lot more intake piping
