True bolt on turbo?

[slyhall]

I purchased this turbo..Garrett bolt on GT2871R-15 .64 AR Turbocharger w/Actuator in 2022 but just now trying to put it on. The compressor outlet and wastegate is a little different. I'm assuming its made for a rwd sr20det which is fine because I have and s15 I will try it on. I keep reading that this and maybe a 3071 will bolt on. Is there something I can do to bolt it on like change some parts from the old turbo? I read here that I would need this turbo but with a gtir housing? I've asked a few places and they don't have anything specific to our cars. You guys know of a bolt on turbo and the link for it? I'm only looking to push low to mid 300's whp

My turbo is pretty much the same although was built by turbo dynamics.

It's a straight bolt on turbo for a 200sx I believe.

Mine has the original gtir comp cover machined to fit so it's a straight bolt on.


Also I got my wastegate ported as the smaller. 64 exhaust housings have been known for boost creep.

Mine is gt3071r T25 .86 rear and is sitting on a stock manifold.

any updates and pic would be good ...im looking into getting a gt3071R myself ...what hp can these sustain effeciiently?
im looking for atleast 400hp to the wheels could be less or more

The shop put the stock turbo back on for now. When I get it back I'll look more into it.

I don't think you get there with gt3071r, i got 360 to the hubs 1.5bar, stock manifold 3" from turbo. Maybe G25-660 or something similar newer turbo, don't forget drivetrain loss from the equation

THANKS will remeber the drivetrain loss ....whats about gt3076 will i be able to pull 400 whp

Is there any reason you go for old technology turbo? In 20 years turbo tech has evolved drastically G25-... G30-... faster spool, better response take your pick.

didnt want to replace my manifold and tomie downpipe

Garrett g25-660 does have a T25 for manifold and v-band exit so no go with tomei ...

yea i know ...but for my power goals 400hp i think ill get away with the GTX3071R ball baearing ...im currently running a china knock off gt28 ...and the car makes 330whp@20psi ...so a better turn should get me closer to that goal

 

[astarozna]

If the internet doesn't lie then gtx gen I-II will come T3, T4, V-band so no T25/28, but yes that turbo would get you closer.

well if i cant get it in the garret i did see it in the pulsar brand ...so one will work

3076 be nothing then on boost high in the revs not ideal
