People got fussy about me asking this out of this thread... so I suppose I'll just stick to hoping you all can help me out. Pardon my noob-ness... but I've been looking all around and struggling with finding the answers I need. This is my first turbo car, and I've just been rocking the stock t25 thus far. Now I want to upgrade while the winter months set in. Here's my questions.
This may sound dumb... but I know what I want, I just don't know what kind of pieces I need! I searched all the threads I could find, read all 16 pages of this thread, and this may be something so simple people just assume I should know or something.
But help a guy out!
- I want a gtx2867R turbo. I'm not interested in advice for any other turbos. All of my questions pertain to this specific turbo. My power goals (for right now) are around 300hp at the wheels, and I've got all the supporting mods I need. Yes, I understand this is not really "pushing" this turbo. Again, not what I'm concerned about. I do not want to go with an external wastegate at this time, and yes, I know the pluses and minuses of choosing this option.
This will be going on an s13 blacktop SR20DET.
Are there different Compressor housing options? (like the GT28 series with 2 bolt in, 3 bolt out) Or does it come only one way?
I hear it comes with an "anti-surge machined" compressor housing. Does this still apply if you get (if available) one of the different compressor housings?
- I do not have a turbine housing. (I've only got my stock T25)
From what I understand, I can usually order one of these along with the turbo for around $200. I'd want the .64 a/r off the gt2871r. I think this is a popular option (from at least what it appears so in this thread)?
I want my turbine housing to be the t25 style that will bolt directly to my current down pipe (aka, any t25/t28 style). If I'm correct, my selection above of the gt2871r's housing will give me exactly this.
- Do I need any other bits and pieces to attach the turbine housing to the compressor housing? Clamps, clips, screws, fittings, etc? If so... what and where do I get them?
- I believe I need some kind of wastegate bracket. Is this true? Can I re-use my t25's? If I need a new one, where do I get it?
- Keeping in mind I want to stay internally waste-gated... How do I know what wastegate actuator spring I need and should get? My power goals are (as I said) a simple 300-ish HP to the wheels. I have all the supporting mods I need, including a boost controller, fuel, standalone, etc... but I just don't know what spring I need. 7lbs seems to be common... but I also see options for 11 lbs and 14 lbs. I'm now confused. What actuator should I get? HKS? Some other brand?
Cliffnotes:
I want to know what all I need for a completely assembled GTX2867r that's as close to "bolt in" as possible into a black-top s13 sr20det.
Thanks for the help ahead of time.
