Here's my 2 cents. Don't even think about buying a chinacharger. I had one and it lasted about 200 miles, seriously. The housings were good, but the CHRA had bearing failure. 200 miles on a ball bearing turbo means it's a piece of ****. I would never buy anything unless it says garrett on it. I am running a T25 from an SR20DET that I bought on e-bay for 200 bucks. I love it. It's rebuildable, it's quality. I am running 7psi, but I was told it would hold 13-14psi to redline? On my car with a standalone, 14psi could be close to 300hp tuned properly of course. I saw a guy with a 2001 make 244hp to the wheels at 11psi. So used garrett...YES, new garrett BB (GT2554, GT2560)...EVEN BETTER, Chinacharger....**** THAT.

i was running a SSAC t3/t4 on my old probe and it was nothing but great from 6psi-14psi. that turbo outlasted a motor, a trans, and a couple of clutches.

ok so one last noobish question: you guys say ebay, but when I log into there and type "t25 turbo" or "gt28 turbo" or "t3 turbo" etc etc etc i get NOTHING BUT stupid bs chinachargers....I mean, do you really have to scroll through like 10 pages of that bullshit just in case there is a real turbo off a real sr20 or 300zx in there, or is there an easier way?

search for "garrett" "garett" "garret" and any other way. idiots misspell them which lets you get a great deal

BTW for everyone that thinks chinachargers are crap..

I still haven't finished mine... But, since we are on the subject of inexpensive turbo choices, the TD04L-13T I'm using (got mine for $130 with 45k miles on it), is an excellent turbo to use on the miata engine. My analysis (post #32 and #51 of this thread: https://www.miataturbo.net/forum/sho...ht=SCCA+proper
and also a couple of other peoples' setups convinced me to go this route.

The only known dyno charts for a similar turbo are from member 4sfed5, who is making 200 whp @ only 7 psi from his IHI vf10, and this guy who is claiming 270 whp @ 1 bar boost: https://www.miataturbo.net/forum/sho...ighlight=TD04L

So, I say, go for it! If I were to redo mine from the beginning I would use the ebay cast log manifold and use an adapter plate.

wow, that is awesome. so looking at those charts, it appears that the td04 is actually efficient in pretty much the whole rpm range. i guess miata having a much smaller engine and being inline/higher compression takes alot less flow from the turbo to put out pretty decent numbers. well then I am 98% convinced, THANX MAN!!!
I always wanted to try that, ive seen a few threads myself with miata's making around 200-250whp on a td04, and ive seen MANY MANY wrx's put down 240whp/290wtq and the wrx has much lower compression than a miata. that is great. the other positive is that i have access to SHITLOADS of wrx tdo4's, my friend literally has a full crate of them from previous swaps (owns a shop), and they are not pos chinachargers that i would have to check every week to make sure its not falling apart. lol

Yeah, you could easily make an adapter plate from a stock up-pipe to go on a manifold of your choice.

As for threads on TD04's I havent seen any at all? Maybe you're talking about the Greddy TD04? If so, that's a completely different animal.

in that case I believe I am mistaken: ive seen threads that say td04 but forget just how large of a family the "td04" is lol, ranges everything from greddy to srt4 stockers to wrx stockers.....my mistake

I just called up my buddy and he has a spare wrx engine for my taking, so hopefully ill folow in your footsteps and go that route when im ready. you say you would have went with a log type cast mani if you could? why is that? the tubular looks much superior in design, or am i missing something?

Oh and threadstarter, if you chose to take the wrx turbo route, hit me up
better price than the chinacharger, GUARRANTEED

Oh I meant if you want a reliable budget build with a 1.6, you could buy the log manifold off ebay. No doubt that the tubular manifold I am using is much superior. Its a shame that ETD doesn't make any more of those, so what I have is pretty much a one-off.

With a 1.8 though there's several other manifold choices that could work, including some that mount the turbo lower down.
