Talking Picking up HKS top mount w/t25 and lines for $300!

Well, I'm going turbo!

Ill be picking this up today. From what I understand, it's a HKS powerdercoated top mount manifold w/t25 from a older sr20. It has lines included. I'll need to make a custom down pipe and also get intake piping.







Video of the shaft play. Do you think I'll need a rebuild? https://www.flickr.com/photos/xxmachonexx/16066886383/

Long story short, I have a newish oem clutch and I don't want to change it again unless I have to so I want to stay with what I believe is the stock 7psi on the turbo. The stock clutch is good for 160whp yes? I'd like to stay within those limits, for now at least. So thats why unless I pick up a cheap intercooler locally, I want to run no intercooler. Right now I have rb header/catless connecting pipe on stock muffler. Wide band is on the way.

Question, will MS3 make the car significantly more reliable than running some kind of piggy back? Significantly as in $1,200 more?

Advice on any level is much appreciated.

Got it! Barely ANY in out shaft play, which I hear is the bad one. It has some up and down play but the blades do not touch the compressor at all. I did now see and understand I have to clock the turbo but what about the following?

Did coolant run through it or something?


What is that hole on the bottom of the intake thing? Is that to recirculate?


Some scuffing inside the compressor

White dust is most likely from running lean on the previous car? Please tell us you have MS and larger injectors planned.

The hole on the compressor outlet adapter is most likely for a wastegate source, although I think the turbo has one built in on the front of the compressor housing. I suggest plugging both of those and adding one close to the throttle body, post intercooler pressure loss.

It either ran really hot, or with race gas? Looks like soot from my dirtbike when I run vp.

Used ms come up every now and again. Be patient, use this time to read all about it. Allofit.

That turbo is a small chunk of what you a getting into. More like a morsel.


Ahh, beat me to it while I was eating with an open browser.^^^^

I JUST ORDERED THE MS3 PnP w/maf delete from 949 for $1,200!!!

I'm planning to stay stock boost of what I believe is 7psi for now so I'm hoping I can run it with my stock 265's and non inter cooled. The temps here are hardly ever over low 90's and usually high humidity.

I am kinda thinking maybe I should just rebuild the turbo while it's out and I don't need it.. I want to do this right the first time around because I don't want to be stuck riding moped for too long in rainy Hawaii. What do you guys think, should I maybe open it up and check and clean or something?

I just noticed the AR 80. Is it a BB or journal bearing? Ball bearing can't be rebuilt unless you buy the chra, for a lot of moneys.

Wants to do this right. Doesn't want injectors or intercooler.

Took forever to find but I might have found a starter downpipe that I can cut & weld to fit my top mount t25. This can make at least the elbow. It's for a sr20 swap Datsun lol

The rest should be easy for a shop to do no?

A shop will most likely NOT want to mess with hacking up a junk manifold, so that you can try and save a few bucks. Go find the correct downpipe for that manifold/turbo you have. If there is such a thing, it wont be on EBAY.
You need to go read a bunch of people's builds around here, read alllll of the stickies and then proceed.

Without a build sheet, you seem to really have no idea what you are getting into.

Good luck man

Can someone tell me a link or explain to me what which lines do and what lines I need to run this top mount turbo? Sturovo is going to make a turbo outlet elbow for me and I see that he also makes lines but I don't know what I need. The turbo did come with some lines as you can see above..

That welded wiener looks like your oil drain, the bent hard line is probably oil in and the two banjo bolts are the water in and out. Look up your turbo manufacturer for proper water flow direction. Probably doesn't matter too much though.

What injectors did you decide to use?
