16g or stay with t28

[DSM Zo]

Right now i have a t28 turbo on my 6bolt swap 2g gst. I have 550cc injectors n 190 fuel pump tuned crappy with a SAFC II and of course exhaust n inatke. My friend has a sr20 240sx and wanting to buy my turbo cause he has the t25 so it made me think of going 16g. I heard the 16g would b better cause of slower spools so more traction but How much hassle will i have with installing the 16g and how soon will it max out the injectors and/or my fuel pump? Im aiming for 260-300 whp range. If the t28 can get me there with current injectors n fuel pump then Im less interested in switching.

A T28 can get you to 260-300whp depending on your supporting mods. You will need more mods to get there. A T28 is about the same as a Big 16G. An EVO III 16G flows a few more pounds per minute. But if you're looking for a turbo to give you more lag for traction reasons, go with a 20g.

The fp t28 almost flows as much as the 16g with faster spool time..Also more traction depending on boost levels..Untill it spools that is..You can find a used small 16g for less than 300, but you could also find an evo 3 for around the same price used..
...
If your really looking at going above the 250 range I would suggest a 255, afpr, and dsmlink, and get rid of the safc..That's if you plan on keep modding..Otherwise just stick with the setup you have, and rewire the 190..

I know im going to want to go further later on but i dont know how soon that will be. Right now i have injen intake, 3" thermal catback with gutted cat (downpipe and elbow coming), and hard intercooler piping(about to go front mount in a lil). Think thats enough for 260-300whp range w/ the t28?

 

[Bud92gsx]

You could also go with an upgraded sidemount IC..They support 350whp and appear stock..Going with a front mount sometimes hurts spool time depending on turbo..

 

[saechao04]

550 injectors won't get you to 300. I have 880's, walbro 255 with afpr, ecmlink v3, fp2 cams, MR exhaust, fb bt28 and I'm putting down 300 whp.

 

[DSM Zo]

Yea i know the front will hurt the spool times but i figured that would help with my traction issues if i keep the t28. Also, going with the 255, afpr, and dsmlink; i should stick with the 550cc? will/can the t28 max those?

saechao04 just answered that question. i didnt see that post before i replied so how far you think the 550cc will get me?

 

[Bud92gsx]

550's aren't going to get you very far..If you have another car and can deal with downtime..I would suggest selling the safc and 550's, and getting what you need to get to your power goals..

Or getting dsmlink, and going as far as you can on 550's, then upgrading to a front mount, or upgraded sidemount and large injectors..Along with the 255, and afpr.

 

[FLASH1970]

If you want to stick with the SAFC for a while, get some 660's-680's and sell the 550's. Get the downpipe and intercooler upgrade, mbc, boost gauge, datalogger and wideband for tuning if you don't have them already. That should get you to around the 260-280whp mark depending on the tune. The 190 pump is good for about 400whp give or take 20 but that's beyond your goals so I'd just stick with the 190.

 

[DSM Zo]

Thanks for you guys help. Keeping the t28 and upgrading to the 255, afpr, and dsmlink, and bigger injectors but i dnt know when im going to do it all because this its my daily driver.

 

[Bud92gsx]

Well theres no reason you can't peice together your upgrades and put them somewhere you can see them..So everytime you look at them you can say I need x more things and I'll be ready to rock and roll..

 

[deek00]

get a dsmlink and 16g, it will get you where you want to be in the end. you already have decent injectors and fuel pump might as well go the extra distance

People really seem to under estimate the power you can get with a 16g. Go for the 16g (Some guys running low 11's with some mods).

Almost nobody here underestimates the power of a 16g, but when the guy already has a T28, which VERY comparable to a 16g, it makes it hard to recommend the swap. Especially considering a T28 to 16g swap would mean he'd need to add a 2g 16g kit to the cost of the turbo upgrade. More money for not a hell of a lot of gain.

Re-Read Thats true..Just read it wrong.

Op if by any chance you switch turbos, i would like to know how much you want for your T28.
Pm me.

Evo 3 16g>T28

Im at 343whp with Evo 3 16g gt, fuel, vrsf IC, Jackal SD, exhaust. 25psi all day with this beastly turbo.

E85 obviously...

 

[FLASH1970]

You're wasting your money on a 255 and AFPR if 260-300whp is your goal... a 190 will flow enough for what your goals are.

A T28 can get you to 260-300whp depending on your supporting mods. You will need more mods to get there. A T28 is about the same as a Big 16G. An EVO III 16G flows a few more pounds per minute. But if you're looking for a turbo to give you more lag for traction reasons, go with a 20g.

True but a seemingly small difference separates the 16g from the 20g also, but there is defiantly a noticeable difference.

Thats a great turbo, hang on to it and get your car tuned... A good investment would be to grab a good FMIC to get that turbo above 15 psi.... your 550cc's will be fine for the kind of power you want...

I'm guessing you've gone through the clutch, and you have a good exhaust, ported O2, etc...

 

[DSM Zo]

Ok, this is my final thought. Get it tuned with what i got now, which is (spec stage 2 clutch, t28 turbo, 550cc, 190 fuel pump, hks bov, safc II, injen intake, 3" thermal catback, downpipe n elbow on the way, fmic is next) all on a 6bolt swap into my 95 2g gst. and also a boost controller would be smart right?

and see what my numbers are. Then start piecing the rest together with the list i posted earlier "255, afpr, and dsmlink, and bigger injectors" because we all know the tune will get old and im going to want more soon or later.

 

[Absit]

You're not going to get much of a tune without a boost controller, but you're not going to pull a whole lot of boost out of those 550s either.

Buy a logger, is your AFR gauge wideband or narowband? If it's narrow, buy a wideband gauge. You can not tune properly without these items.

 

[400hp93talon]

I think Flash and Bud told you exactly what you need to know to make the power using some of the parts you already have. I wouldn't have told you any different.

The nice thing is that you know how to listen!

 

[DSM Zo]

Im still young (18) and learning so i have to listen to people that experienced things i do and dont want to go through.
I have a boost gauge, oil pressure, and afr gauge that came with the car but they all are POS's so imma go with all new one's. I know already about the widebands. And last question. Is the electronic boost controller really worth it over the manual?
