I have a s14 SR with a blown t28 , I got priced on a re-build and it was way to expensive I'm probably gona end up gettin a used turbo but what kind of turbo shuld i look for what would be a good bolt on to the factory manifold and dump pipe? I have stock injectors,stock ecu, walbro 255lph fuel pump, stock MAF, greddy type M front mount,greddy RS BOV, and some other stuff i'm thinkin about a GT2871R one of the two trims , or a GT28RS what do ya'll think??

It depends. What do you want? Are you trying to drift? Do you want mid-range power and driveability? Or more high-end? Do you have a power goal in mind?

Although it's a self-plug , David's^ post isn't a bad idea since a GTiR T28 is a fairly inexpensive solution that can produce a good amount of power (300+). It's journal bearing, so the response won't be as good as a Garrett GT-series, but it can also be rebuilt if need be (where a ball bearing turbo can't). It'll lag more than an S14 T28, but the top-end is much better. You'll need to modify it to fit on your SR; you need to clock the turbine housing, and then do some cutting/welding modifications to the compressor housing. However, a better solution for you would be to swap the comp housing and backing plate from your S14 T28 onto it, and then you wouldn't need to cut or weld. The comp housing swap should give you a little more power and response, as well.

A Garrett GT28-series will cost you more than a GTiR, but will have better spool and mid-range. Peak power capabilities will be a little better than the GTiR turbo, as well.

And with either option, you shouldn't run any more than stock boost unless you want to blow something up. Not until you can afford fuel injectors, Z32 MAF, and a tune.

Can't go wrong with a Garrett GT2871R in either .64 trim or .8 trim. They spool fast. Great turbo.

keep in mind that if you go with an upgrade like gt2871r, you have to get turbo lines, injectors, maf, and tuning: eather safc, stand alone, or rom tune like enthalpy. Thats an extra like 1500 bucks in supporting mods, but in the end its worth every penny.

By the way, no matter what you go with, do yourself a huge favor and get braided stainless lines. You do *NOT* want to deal with the sh!tty stock hard lines, seriously. Saving yourself from the hour or more of cursing and frustration is well worth the $ you'll spend on the lines.

I spent 1 1/2 hours trying to get one line to bolt into the block. One.

Wow, if it weren't for the fact that I just spent tons of money on books and a Xilinx FPGA I would totally take that off your hands.

Well if he can't get a T3/T4 to bolt up then that's his problem.

The factory manifold is a T2 flange, while a T3/T4 turbo, well...is not. Maybe they would "bolt up" if you happen to have welding skills, and a machine shop in your backyard, but I didn't really get that impression.

I just used a hack saw and cut off the T2 flange and JBWelded the turbo straight to the the manifold. It took about an hour at the most. WAAAAY cheaper then buying new manifold and all that business

yes definitely! pushing 15 psi on the stock t28 is almost pushing it.

I want that blown S14 T28. If I pay for shipping, would you send it to me? Technically, I only need the compressor housing and backing plate for that side. It would fit in a flat rate USPS box for $10. I don't know what would be a fair offer, but I guess I'll give you $40 shipped for that blown T28. Email me and we can talk: [email protected]
