Internal wastegate fail +3!

Just put a motorcycle cylinder head, put a micro Windows chip and make it rev to where it says Made in Chinatown.

Ebay chinachargers T3/T4s are still a win win situation on a 1.8 block...

check the wheel when you unbolt it. A lot of cheap ebay turbos cut off material off the side (the flat part that rests against the back in this pic) to balance the wheels which causes them to fail quickly sometimes even at low boost. Good turbocharger manufacturers such as Garrett cut off material from the end like this pic. They can do that because their wheels are not much off balance while cheap manufacturers need to remove a lot of material to balance their wheels. Last month I read an article that explained and showed bunch of pics but i cannot find the damn link :(

On the image above the wheel strength is not compromised as in this one thats the usual ebay special that usually tends to explode under boost..

and holy crap heres an ebay turbo for you.

Well here's the dimensions
Compressor: 2 3/4" (I thought it was 3" when I took the pic, so could be deceiving in image)


Turbine: 2"

Nono - get a set of calipers and take accurate measurements (within .01") of the inducer and exducer of each wheel. We can't tell you much about that turbo using tape measure measurements.

You're kidding, right?

Although that is more accurate than the distributor's information.

Whatever!

Know tons of people with chinachargers running super strong back in Puerto Rico, there is a forum (but cannot find it right now) that has a complete section of only chinacharger Hondas running them, some even go to the race track. Anyway, I do not want to hijack as that is a topic for another thread.

measure the inducer AND exducer dawg.

best I can judge it's a "2871" 48 trim wheel.



FWIW: I'm running a $150 ebay turbo.

Stop hating on internal wastegate, it has feelings too.

And it won't be operational for 2-3 weeks, but once it is, I'll post full data logs.
