Ported or otherwise modified turbos

[peepsalot]

Who has modified their stock turbo and cares to talk about it?
Can it easily be ported without screwing anything up? I noticed the other day how thick the metal is around the compressor outlet, it seems this could be widened significantly.
Also, what are the options for different turbine or exhaust wheels on the stock turbo, and how easily can that be done? What advantages can be had(quicker spool, more flow on top end, etc.)?

i would ask MPNick, i think he offers a porting job on the T25R.

Just ported the wastegate last week. The turbo is still out, so I might mess with it some more.

Cool. You didn't see room for imporvement on the compressor side? I was just amazed at how thick the metal is there, where the turbo -> IC pipe goes. I don't know if messing with that would screw up it's ability to compress properly though.

I don't have the proper tools to get that deep into it. I wish I did though.

 

[peepsalot]

So what tools did you use for the WG? Just dremel style? Why not use the same on the compressor?

 

[CustomMSP]

Dremel. It took me a while with the small bit I have. I couldn't find a bigger bit in Home Depot by me.

my friend had creep problems and did this porting job.

So basically the compressor housing and wheel have been replaced?
What's the difference between going that route and just getting a GT28rs? What is the stock trim on our turbos?

It's amazing how tiny the stock wastegate is. I never knew...

 

[Mr. Win]

thats a turbo off a turboII rx7... but similar anyways.

The compressor housing has been milled out. A new compressor wheel is installed. Looks completely stock from the outside...hehe.
Its cheaper, spools up exactly like stock, and has been proven at 330whp at 15psi (with other mods.) However the GT28rs will still make more power.
I have no idea.

 

[FSDET]

how much did that cost ?

 

[Fast lane]

i think its around 900$...but im not 100% sure

 

[FSDET]

wow thats pretty expensive considering a new rs is around a 1k

 

[Mr. Win]
