Cheap build, need opinions
 

ok to start out i knew nothing about turbos a month ago and nothing about miatas 3 months ago. i bought the the car and got it home and there was brand new turbo header in the trunk. i couldnt throw it away. so i found this websight and started reading and searching ebay. total build is less than $600. every thing from the internet somewhere. or i made it from stuff laying around shop. take a look at pics and if see something wrong please tell me, i havnt drove it yet, it is going to dyno in a couple days to get tuned. stock engine, 7psi,no intercooler, 12 to 1 fmu,

oh man, you are rocking a chinacharger? this is going to be interesting:giggle:

WOW, talk about ghetto....you should've read more here before touching your car. Have you done anything about fuel? Have you started it, driven it? If so how does it run?

he specifically stated that he didnt drive it in original post.. but if he's got nothing on there gesides whats listed id LOVE to see a vid when he does drive it lols

You'll need to brace that manifold to the engine block from the turbo flange. It will fail from all the load of the turbo and downpipe. Why did you build that funky (albeit well constructed) intermediate transition from the manifold turbo flange to the turbo flange? And saying it was to get the turbo to fit the DP is not the right answer. ;) The last thing that mani needs is more weight on it.

ummm... does that dark photo show your oil return going below the bottom of the pan and back up to enter it? that won't work.

You can clearly see a Vortec FPR on the firewall.

Your turbo looks like my garbage disposal... Just putting it out there.

I'm very interested in how this turns out, keep us updated on the chinacharger/ebay combo works out. It looks like you used an e-bay tubular manifold, I hope you can weld.

Nice ninja edit :bigtu:

I actually went back and re-read it and it said he hadn't driven it, but didn't say whether or not it's been run yet.

Also the first two pictures don't show a FPR which is where I looked for one initially. Good try though.

It almost looks like he tapped the bottom of the pan.

He said he has a 12:1 fmu.

I missed that part as well ... I focused on the 7psi bit, to me that indicated he's driven it. I'm guilty of skimming the post :(

And if you'll notice in the first picture there is still a header and no turbo.

Damn, I even missed that the second time I read it, I suck.

The second picture the turbo is in and there is still no FPR, I don't feel bad about missing it though, not like the original post had the best format in the world anyway.

there's one for the mustang club:

That or the supra club

im thinking they should start a chinacharger club, more and more are starting to use those things every day

i plan hiding the hole with scoop or something. i have the ran the car, it seems to run and rev fine, but with no gauges on it i will wait to drive drive it. i assume it will be 7 psi because the guy i bought the turbo from says the waste gate is preset at that. i have no idea what it will actually boost. i did install a 255 lph fuel pump, and the fmu, turned the timing down. other than it is stock. the spacer under the turbo is for the dp, turbo was almost against firewall with that header, didnt know what else to do.
what do i do with the open egr line?

Sorry if I'm hurting anybody's feelings here but damn man, reading that almost gave me a headache. Is english a second language to you...some parts sound like it may be which is ok, I'm just wondering. Try to use a little better grammar and you will probably get better responses here.

I would really advise investing in a wideband O2 sensor (LC1, AEM UEGO, etc..) and a boost gauge, wouldn't take someone's word as to what the wasegate pressure is.

just cap the egr port, if you can build a spacer for your turbo you can build a cap for the egr port.

that turbo is too big for our cars, find yourself a smaller t3 on ebay and sell that one (my advice)

brace the shit out of that manifond, it will crack...over and over and over and over and over and over again!!!! you get the point

boost gauge and a wideband should be a must for you.
look around in the classified sections here, clubroadster.net, and miata.net, there is always something for sale.

get some colder spark plugs and a pcv from a 323 turbo car (oem mazda only, not the napa bullshit)

post a better pic of your oil drain line...can't really tell what it looks like

good luck
