Blew my B16g, what are my options?

[4gfun]

Kind of happy that I finally blew this thing due to the problems I have had since I got the car with boost fade and blowing blue smoke at WOT. (Seized compressor wheel)

If I want to stick with my FIC 650s on pump gas and continue to run 20-25 lbs I'd like to know what my options are.

I'd also like to know what my options are if I was to go with bigger injectors and take out the presently used Walbro 190lph and put in the Walbro255 I have just laying around.

I have never really taken a look at turbos since I started my DSM/GVR4 days many years ago because I have never had one blow.

I want to keep the price down in my case but want to know what my options are from a few different angles.


Thank you

Junior at turbos, but read a thread in here where running the Evo X inducer would be a waste for some reason. That's all that I gathered.

Not a waste, it's just an odd combination. You'd need a 14B or Small 16G cover to make it work because the Big 16G cover's inducer spec is already cut too big- however, the Small 16G and 14B center housing would need to be machined to fit the Evo X compressor's exducer.

If you have a Big 16G center housing, you wouldn't need to get that machined....but you would need to find another cover.

I see, well thank you. I sent you a pm as you are probably aware. Please take a look when you have some time.

Thanks

Will do. I've replied to 72 PM's since Thursday (no lie), so I'll get to it as soon as I can.

Lol, that is ALOT of pm(s). Get to it when possible, no worries.

Thanks for EVO X wheel explanation justin

Thanks all, well since I have 4 other cars I took my time getting around to this. Looks like the center is scored up...not horrible but it looks like it did make contact in the past due to some shaft play or??

The question is, how do I know whether or not the center rises to the threshold of "junk"?

Also, how do I get the turbo far enough apart to measure the compressor inducer and exducer size? I pulled the clamp to separate the hot and cold side. I see a 10mm nut on the compressor side and a 13mm 12 point nut on the turbine side.

Finally, I see that the housing is a 7cm2 housing (hope I got that right). It has some cracks (I hear that is common) that do not go through the housing. How do I know if I have too many cracks etc. Don't want to get rid of the housing if I don't want to because the turbo is externally gated so someone welded the wastegate part of the turbo shut. (Not sure if that was the right way to do it).

Thanks for all your help.
