looking for

[240sxbobbis]

ok well im going to have to replace my turbo and im looking for one to purchase what would you guys run for a good set up not after any outrageous power but a substantial amount . and how much would i have to cough out on it ,

lastly how much would u sell it for ?? honestly

[CadetLD]

Im guesing your replacing a burnt stock t-25 turbo. When mine blew I opted for the S15 T-28 because it was Dual Ballbering (sp?) and a quicker spooling design than the S14 t-28s (so Ive heard). Ive heard the Evo 16gwhatever is a good turbo for 1.8-2.0L engines and can support 350+hp but will need some fabrication to the exhaust manifold unless there is one made for those turbos but I doubt it. Im no CA guru but im quite happy with my turbo. it feels like my stock one running 10psi and spools quicker at only 6psi. not to mention it spools much louder if that matters to you. Common sense should tell you not to get one of those cheepo ebay turbos that will start leaking in a few months. Usualy you get what you pay for.Im sure there are many more options than those two but both turbos ive ridden in cars with them. The evo turbo was in a talon mind you. Check the stickys there might be somehting more informative than my jibberish and more details will lead to more answers. good luck! -Shane

Edit- Those two turbos I mentioned are in the $400-700 range give or take tepending on where u get them, dont quote me on the evo turbo though.

Just rebuild the old turbo with a rebuild kit from ebay or something and call it a day. Thats what i did and ill be posting pics soon... so keep a look out for my thread. Its like $75.00 bucks for a rebuild kit and a couple hours of your own time and bam! Good as new!

[missionsix43]

If you want more power, now would be the time to upgrade. Stock turbo is nearly maxed out stock. That, plus it being a pain in the *** to remove the stock manifold/turbo, I would DEFENITLY upgrade to an s14 t28, if not an s15 t28.

ok whats about the rb26dett t28 my friend is giving it to me for $0.00 bucks but what would need to be done i know lines down pipe oil lines but what do u guys think ? also what are you all running. hey ricardo good write ups by the way keep it up also i cant wait for the other one about to turbo .

+ balancing. After a turbo is taken apart, it must be rebalanced. Otherwise it wont last very long.

i have a 18g turbo that came off my CA18det ill let it go for a good price zerothread/172702

aren't all the skyline turbos t3 flanged? i know the rb20 and 25's are...i don't want to crush anyone's hopes and dreams or anything

if you only want a mild increase and don't want to spend a lot of money, i'd go for the s13 redtop t25 ($75-$150), buy it blown (cheaper), get a rebuild kit ($75), have it professionally rebuilt (i think i paid $75, do it because it needs balancing!) and buy an hks actuator($100)...around $300 for all this brand new and at 12 psi, mad brutal, especially if you're used to the stocker, plus maybe 200 higher rpm difference in spool but much stronger in the top and as easy as turbos get to install, uses all the same stuff, you just gots to clock the housing...just my twonies

and if you want, i have an SR t-25 from a blacktop i'll sell you for 175 shipped, i got it off my motorset i bought off of oversteer here on the boards.

This may not exactly be true. I've read that many of the T2 series turbo's by Garrett aren't balanced as an assembly, but as separate components (compressor impeller and turbine impeller/shaft assembly). When I rebuilt my SR T25, I just marked the compressor blades orientation in relation to the turbine shaft and just re-installed it that way.

I personally can't testify yet that this is OK, but I've read in multiple places on the internet people doing it exactly like this with out any problems.

Of course it's safest to balance it, but do some research before you just tear the turbo apart.

so what about the t28 off of the rb26 there was a thread i read on boost cruising a guy had fit one on his ca and it ran nicely

[fitch9014]

when you're speaking of speeds and tolerances at which turbos operate, even cheap ones, i would think that balancing would be crucial to safe operation. i mean even if they were balanced seperately, they would still have to meet the tolerance of the other pieces, right? that said, if you did it and it worked, who's to say balancing makes any difference. what kind of boost are you pushing through it?

and aren't all skyline turbos t3 flanged?

[c-rad]

and aren't all skyline turbos t3 flanged?

Only the RB20/25. 26 uses T2 flanges. The T28's from the rb26 flow less than than a T28 would from an S14/15. The compressor housings use a much smaller A/R. Remember, only 3cyls and 1.3L of air is running each T28.

[r34 gtr]

i think that s15 turbo is right down your alley.

[bentvalves]

In the stickies it says something along the lines of "dont go whacking on an s15 t28 and then complain about turbo lag" wich kinda caught me off gaurd as that turbo is dual ball bearing and an OEM unit.

Larger hot side I suppose, but I couldnt imagine lag being an issue with that turbo.

Im shooting for 300 hundo to the wheels with that turbo, stainless manifold, head work, and 256 cams.

My objective when choosing that setup was quick spool with good numbers up top, hope I get what I was looking for!

why don't I ever hear people talking about gt25 turbos? if your looking for 250-270ish whp wouldnt a gt25 get you there with a better spool vs. a gt28 (or any t28) or no?

[240sxbobbis]

i think the t28 from the s15 is where im gonna steer

yeah, the gt25 is pretty decent, i drove one with a hks gt2510 and it'swhere it's at, but man, they're expensive. best part, almost no lag, but there weren't any butterflies hooked up either (no low end). if it were me and i was going to spend the money, i'd try to find one of these, as opposed to the (g)t28...

[jt15833]

sorry to sidetrack but when ppl talk about these 400-700 dollar turbos (give or take a hundred) are they usually talking about used s14 and s15 t28's? I was looking at garrett's and the gt25's look to be 1000ish. what other kind of options are there? is a nice t25 a practical solution for someone who wants 260ish whp?
