fpbigt28 fuel system

[ruzzi360]

hi, i decided to install my new turbo during the winter along with fmic, and i was wonderin since the turbo has a 17psi actuator, what should i get to give this set up more fuel.. i was thinkin an safc2, 550's, and 190-255lph pump..i just want ur opinions what to do in order to run 22lbs on hi setting on my boost controller...should i buy the whole system together or can i make due with one part at a time? thanks for the help

A 190lph fuel pump will be suffice, along with 550's and the afc of course. I currently use the 255lph fuel pump which is probably over running my fpr, but my car still pulls very strong at 20 to 21psi.

 

[ruzzi360]

thanks for the help, i see alot of ppl pickin up the 255lph. so i guess its alil too much for my set up, but i do have future plans to get a bigger turbo..but 190 is good for now.. how well does the fp bigt28 perform at 21psi, cuz i was thinking around 21-22 for my hi setting...does it pull u back at all, and what rpm do u usaully reach 20psi?

No problem man! At 21psi the car pulls very strong, even more so now since my HKS 264/272 cams have been installed. Before I had installed my cams, act 2100, act flywheel and the FP 17psi wastegate acuator, I raced a friend of mine from a 40 roll, he has a 96 talon awd with a ported and clipped TRE 18g, fmic, along with all the other supporting mods, including dsmlink. I could easily pull on him by two car lengths. We did about three pulls, and it was the same out come everytime. We were both running 20psi at the time on pump gas. He goes by whatturbo on the boards. I hit full boost in about 3500rpm's give or take. It's a little more now since the cam install, but makes up for it on the topend.

Hi,

I had a FP big T28. I have the 255 lph fuel pump, S-AFC, 550cc injectors. I also upgraded the fuel lines to -6an lines, AEM fuel rail and fuel pressure regulator. It's an overkill but I wanted to have it when I am ready to upgrade to a bigger turbo. I ran 18 psi on 91 octane and 22 on race gas. I talked to a guy that had a simular setup and he ran first a S-AFC but changed over to DSM Link. He told me that he noticed big differences. IMO, I would go with the 255lph fuel pump, don't go in between. Because then you have to buy 2 different fuel pumps. 190 for now, and a higher flowing one if you want to have a bigger turbo. It's better to overkill then to do it twice.
If any more questions, please feel free to leave a PM.
Thanks,

Sven

A 255 pump for a t28 is like using 1000cc injectors on a 13g car.

Get a 190.

 

[herostar]

I used a 190, 680's, and an safc on my old BIG28 for a while and it pulled awesome at 20psi. I deffinately recommend the 190 pump. It's quieter and doesn't over run your FPR. Have fun!

 

[ruzzi360]

thanks alot for all the help guys. djsven, im the one who actually bought your fp bigt28..i cant wait to put it on... im still in between tho cuz one of you guys said go for the 255lph, and all the others say go for the 190lph. i plan on upgrading to fp green next year but for i think the t28 can supply some fun for the track in march..any of u guys that have or had a t28 got any eta's for me, to see what they can accomplish...thanks alot once again..

Here's my thought process regarding fuel pumps...


The 190 is a good cheap upgrade with which you need to do no extra supporting mods. It has made over 400whp many times. This number 80% of all dsm tuners will not ever reach, or for that matter come very close.

The 255 requires a FPR for your car to run at its maximum potential. It is also loud.

IMO go with the 190, and if you ever end up needing a bigger pump, you might as well go to the supra pump because it's quiet and flows enough for over 700whp.


The way I see it the 255 is sort of an in-between pump. I know I sound like a hypocrit because I run the 255 pump, but that is because I was in a pinch, and ended up trading my 190 for a friends 255 so I wouldn't run too lean at a race last weekend. A supra pump and fpr are next on my list of mods.

Instead of starting a new thread, im askin here since my questions is almost the same. i want to upgrade to an evo III 16g. if keep the boost down and install a 190 will i be alright without an AFC? evenually i will upgrade the injectors. and, how much boost can u run with an evo, 550's, 190 with out upgrading the intercooler, or will the intercooler max out b4 the injectors?

 

[Stapl3]

Those injectors will take you to the limit of that 16g.

Look for a Supra SMIC.

 

[turbo4g63]

alright. so how many lbs of boost with a evo 16g can the stock ic handle?

 

[herostar]

You'll be fine as long as you don't run much over 16psi. Once you get the injectors you can run probably 17-18, but I wouldn't go past that until you get a better intercooler. Once you get a better intercooler you can run as much as your car will allow... just make sure you have a logger to keep track of what's going on.

 

[turbo4g63]

thanks for the info. one thing i still need to know is, if i do upgrade the injectors, will i have to get a afc along with the logger or will i be good with no afc or logger under 19 psi. sorry for all the questions but i gotta figure this before buying.

 

[herostar]

Once you get bigger injectors you NEED SOMETHING to compensate for them. Whether it's a MAFT, DSMChips.com chip, safc, dsmlink, or standalone, you need something. The easiest/cheapest way to tune it right is with a logger/safc. I picked my setup up for under 300 using ebay.

 

[GstPat]

I ran 14.2 @ 102.8 with my fpbig28 turbo 15psi with stock injecters, 190fp, street tires and stock smic. My 60foot was ugly soo yeah bad times.

About buying a part at a time.
Most people say you can run higher boost with a bigger fuel pump but w/ the stock reg and injectors I don't see how that could help a lean condition because it won't give more fuel.
190+550s+safc should be all you need. That 17psi wgate really limits the steps. My normal t28 could hold 12psi most of the time until it would creep to 20 psi after 5k.

I am running a 190 hp with 450s at 53 psi base(500cc)and I was running 18-19 in the summer til fuel cut came with the cooler temps. I am still "tuning" but I only have -4% correction at redline stepped from -10 at idle, I could probably get away with -6% because I barely touch 1500^s at the end of 3rd. I'm running 16-17 psi at the moment unless it is colder than 35^s out. I will probably buy 550s when I feel like it although the car is plenty fast for me at 18-19 psi.
Get the high pressure 190 because it flows slightly more than the 190.

 

[DSMJim]

The over run on the fuel pressure regulator from the 255 is a small amount and can be tuned around on the SAFC. It builds 1psi of fuel pre 1psi of boost just the same only that your base pressure is now 5-6psi higher. This is just added into your tuning that your already doing for your 550cc injectors.

With that being said it is over kill, the 190 has gone 400whp and is much louder than the 190lph is plus you need not worry about what the over run is.

It's okay but don't expect it to turn your engine into a beast. It still has alot of the same characteristics of the T25 including quick spool-up, excellent mid-range, & despite what some people may say it does fall off in the upper RPM's, just not as bad as the T25. I had one and was disappointed as it isn't worth the money. It would be a good $500 turbo but at $750 - $800 new there are far better turbos to be had.

if im gonna spend bucks

i want to feel my investment everyday when some a hole tries stuff on an empty street

that tells me that i get what i paid for

You would be better off to get the Evo 3 16g then.

Hi,

I also would say that the Big T28 was a disappointment. I don't know about the evo III big 16G, but if you want to be put back into your seat, I would say go with a 50 trim at least.
