T28 decisions decisions....

[re-rx7]

Having some trouble selecting a t28. I see the garrett and the FP t28. My question is are there any differences? Do they both bolt on like stock? Im looking for 260-280 whp so I wanna go this way for the sleeper look. Lol. The price for the Fp28 is almost a grand. Where as i can get the garrett for around 800. Any input is appreciated.

I have a completely stock appearing FP big t28 setup on my car with even the stock airbox, intercooler piping and a 3" stock appearing exhaust that uses a chambered muffler and cat. It feels much better than before but using dsmlink to estimate hp and torque I believe my best numbers are 255 hp and 280 torque. It feels like a strong naturally aspirated car launching and does good going through turns in the mountains. It still doesn't give me the strong turbo pull I am used to and like so much from my Buick Grand National. I bought mine brand new on Ebay though for 400 dollars with all gaskets and hardware from someone who bought one but then sold there car so its no regrets. I do not think a full weight 2g with 300 whp is much of a sleeper though. My car is "quick" but not fast. I think to get the full advantage of this turbo e85 fmic and cams are necessary.

I was curious about the e85 and suggestions?

Been thinking about buying a fp manifold. Really wanna keep my heatshield though, im looking at the 2.5''dp. 3" necessary?

You're right, I don't even think you can mate a 3" dp to a stock O2. I'm not sure if the fp mani would help much over a ported 2g mani on a fpb28. I'm sure it wouldn't hurt. I'd recommend a heat shield, though, even if it's aftermarket or home-made, or you might bake things under your hood and your hood.

+1 on the heat shield I managed to melt a portion of the stock fan blades.

Lol sounds like a super stock looking setup. T28 with heatshield and 2.5" dp. I will be running a walbro 190 and Evo injectors. The idea is stock looking 280whp. Thanks for everyones input. I like the porting idea i need to find a die grinder

I have the Megan 3" downpipe and it mates to the stock o2 housing fine and is great quality for the price.

Make sure to get dsmlink also as you need a way to tune. The safc is going to work but not as well as dsmlink.

The way I look at it the t-28 is the 2g's 16g.
Everyone says a 16g will get you further that a t-28 but its hard to say because everyone jumps on the 16g bandwagon and never true pushing the t-28 to its limits. Look at how far the 14b has been pushed. With enough effort im sure you could take a t-28 past the 300whp everyone says its limited to.

I had a t28, and evo3 on the same car, same setup, on e85. Not even close. I would say a t28 compares more to a small 16g.

I personally didn't find a need to port anything on the big t28 after talking with shops. Most told me that the difference is so slight you likely will not notice or feel anything with that size turbo. After you buy a die grinder and a good high carbon carbide you will likely be out almost 60 bucks and unless you have a good 220 volt compressor your going to be sitting there half the day waiting for it to keep catching up because the die grinder uses so much cfm. You likely would want to ask a local shop to use there air for a few hours for a fee to make it easier. After you spend that much you could have just bought the larger evo 3 o2 housing. I personally do not think with your power goals you need to port the turbine or manifold. You wouldn't have to take the manifold off either during install making it easier and less gaskets / studs to buy.

All suporting mods. Hahn Smic. DNP exhaust manifold. Variant racing atmospheric O2 sensor housing. Punishment Racing 3" ss downpipe.

I have a 99 with the flashable ecu.

 

[LandSpeed-DSM]

I would sell the Flashable ECU and put the money towards V3.

His question is towards a turbo, don't see why it's come to a DSMlink vs Flash set-up. PS, for link he'd still need to buy a new eprom ecu...that's money down the drain for nothing.

Back on subject, the BigT28 is a great turbo. For a daily driver you'll definitely have fun with it, spools very fast . It's price is quite high but you can get them cheaper rebuilt if you don't want to spend too much. I was going to buy one but my funds went on the negative side, pm me and I can send you a link to someone selling one.

 

[re-rx7]

Will do. As far as link ive studied both and im gna stick with the ecu i have. Does everything i need it to. I cannot state enough that this is not a all out build.

 

[4g63tc]

^ Same here, I did enough to make me happy

 

[bmoha7321]

For a street car I think the T28 with nicely balanced supporting mods is a great setup. Great turbo for a big SMIC. Fun turbo for low speed autocross & still fun for high speed autocross events but then of course you're going to quickly see other modifications become neccessary. Big T28 is enough turbo to kill stock clutch. After its tuned Big T28 is enough turbo to kill ACT 2100. I didn't feel bad about killing my 2100. I just felt like I graduated to the next level.
Next turbo for me will be FP 68 HTA.

FP crams all sorts of crazy stuff into the MHI housings, why is it T25 and T28 and that is it? I believe the T28 will be a great turbo for you. If you choose to go bigger in the future it would be nice if there were another option. Nissan's seem to have accesss to every flavor of (G)T2_ imagineable, but only 2 for the DSM.

Let us know how you like the flashable ECU. Seems like fun to me.

FP can weld a coupler onto the green or red to make it appear like a factory t25 to the untrained eye. I wouldn't use one with the side mount though unless you were on e85.

My favorite car with a FP big t-28 on it: Far North Racing - The Car

 

[re-rx7]

Luckily i have upgraded the clutch with a 6 puck southbend. I really want this build to look stock and retain the stock driveability. Since i live in Texas i have access to 93 octane, I feel 260-280whp is def possible. I chse the T28 after alot of research on what I wanted from a turbo.

Damn i love the numbers.

T28 needs to be ordered where is a gd place to buy? , got a great deal on a brand new Hahn smic. Gna be on stock dp for a lil bit. When im doing this what will i need to replace as far as bolts and gaskets? Which ones ahould be replaced? Gna do evo 550cc injectors and stock pump till i get some more money. So ###### run wg pressure for the time being.

I have the flashable ecu and BC, UICP, Hahn Smic, Aem WB, and supporting mods. All i need are the 550cc and the 190lph. Well im not really looking at the Fp T28. Im lloking at the regular T28. I really cant see the difference.

No one wants to mention a T25 to 28 conversion? Even with balancing, that wouldn't cost anywhere close to what you're talking about paying... I haven't seen it done much, but I considered it prior to getting my 14b (which you can install without the $200 install kit fairly easily). It would be more work and not nearly as convienent as just swapping in a normal T28... Just a thought.

As for the clutch, it's good you already installed the puck disk. I am having to replace my clutch and flywheel this weekend because the 14b destroyed the OEM clutch the PO installed in about 3 months, which only saw a year or less of use on a stock T25 setup. I don't think the pedal was adjusted right though, so I'm sure that contributed to an early demise. The T28 would do about the same with a few hard launches and some aggressive driving.

Yea when I bought the car the lady had already put a new stock disc in. Since i do mostly hwy pulls that clutch didnt last long at all. i installed a Southbend stg 3 6 puck clutch off ebay. Cost me $140 and i have no complaints, pretty strong clutch. I thought about sending mine in but, BNR (people building turbo) said it wouldactualy be cheaper to buy out right then pay for shipping to and from.

I haven't looked at Garrett prices lately, but why just a regular T28 and not a GT28? I thought the ball bearing 28's ran somewhere around $1k also, but with lower friction and faster spool... I may be way off the mark though. I haven't checked in a while.
