upgrading from FP T28?

[eclipse_turbo97]

Looking to upgrade from my FP t28. Looking for a good streetable turbo that is still fast spooling. Was thinking about a evo 3 16g, but i have heard the boost creeping extremely bad. Have some fuel mods such as 510cc injectors, 225 walboro. Will most likely pick up dsmlink or a safc for now.

The evo3 16g is not an upgrade to an 11 second capable fp t28.

Your 510 cc injectors are not enough even for your current turbo. Get some more injector (flow that matches your goal). A t3 stage3 50-trim spools pretty fast. But, the new fp18g likely is what you're after. Fast spool but flows well beyound an FPt28/evo316g turbo.

What is your horsepower goal?

There's more than one way to skin an issue with boost creep. Let me count the ways: 1, 2, 3...

What Matt is trying to say is that you may wish to look into bigger injectors, not necessarily more injectors.

I think I was pretty clear . Smart a$$es are good for something though .

. . .Oigh! wait 'til you get to my post on the 2g head in the cylinder head and short block forum. . .

 

[eclipse_turbo97]

you was actually very clear and after I posted this i actually looked at the fp 18g turbo. seems to be a nice turbo. I will be going with FIC 850's with whatever turbo I do choose. Have also checked into tdo5 20g's. I didn't think the fp t28 was a 11 second capable turbo though.

Edit: horsepower goals are anywhere from 330 and up. Would like to stay in mid 300 range though.

Supposedly the FP Big28 has run an 11 sec 1/4 mile. It's also capable of your power goals IF properly supported. I'd first recommend HKS 264 cams or equivalent, FP 17 psi wastegate actuator properly tensioned, DSMlink, install the 850cc inj, maybe even a lighweight flywheel. And finally add in a whole lot of WOT tuning and some high octane race gas if you want to really get serious. Those are some of my favorite/effective mods on the T28. This setup produces enough torque to destroy built AWD transmissions from a roll, ask me how I know

THEN, if you needed more, then I'd buy the upgraded turbo. You'd be trading off a little spool up for increased midrange/top end which is a fair trade. If you don't fully support the turbo, all you'll get is the extra lag with minimal increase in power and that isn't any fun.

You have a good street turbo. What you need is tuning and boost. With the FP T28, the difference between 15psi and 25psi is unreal. You'll be surprised how hard it hits. I drove my T28 car for awhile at 15-17 psi and it's "eh." Then I tuned it with DSMlink and had a new car at 19psi or so on 91 OCT. Then I sprayed meth at 24psi.

Robert at FP told me "the turbo runs well at 25psi." And it does. Midrange of course, and well supported I might add. The torque = (see pboglio post. Also, read through some of his old T28 posts.)

First thing to do is get DSMlink.

 

[eclipse_turbo97]

I borrowed a friends dsmlink for a few weeks to see what it was like and ran around 18 pounds. I am running about 14 pounds on stock ecu and a walboro 255. I couldn't get it to hold boost before when I had dsmlink in. hopefully with a fmic and all new pipes and couplers I can fix the boost leak (stock smic had holes drilled in top??). I dynoed to 237hp on 18 pounds and 99 octane with dsmlink.

Why exactly do you want to upgrade the T28, is there something physically wrong with it?

 

[eclipse_turbo97]

nothing wrong with it. Just wanting more power I guess you could say....

 

[pboglio]

A dyno pull of 237 w.h.p. @ 18 psi is actually decent considering your current mods and complete lack of tuning. I'd be willing to bet that if you installed an 18g or even that 20g, you'd make very little extra power if you redynoed at 18 psi.

As an example, a stock EVO with a honking big turbo makes only 235-255 w.h.p. running close to 20 psi peak with the boost tapering off near redline. That includes a decent sized front mount I.C. too. Yet that doesn't mean the turbo is at fault, in fact that very same turbo is good for 400 w.h.p. on a properly tuned and supported setup.

If you are looking for over 400 HP some good streetable set ups are 50-tirm, S256 for a bit more potential than a 50-trim or an S258 beyond that.

 

[eclipse_turbo97]

Has anyone tried the bullseye to4b m-trim

 

[joeracer321]

The M trim flows 38 Lbs/min I think, so you would be pressed to squeeze 300-350 to the wheels out of it and thats maxed. The V-trim would be a better choice if you are looking to go that route.

 

[eclipse_turbo97]

I didn't know about the m-trim and one of my friends has the v-trim and it pulls hard. Its on sale at slowboy too!

 

[MaddMatt17]

I would go with a little bit bigger too, i had the big fpt28 and it was indeed a hard pulling turbo with some good mods. I'm switching to a 50 trim right now, mostly not for whp, but because the t28 is too fast at spooling and making it harder for traction issues... thats probably the main thing for me

 

[aero_sallee]

If you don't have any kind of VE enhancing mods, cams/ porting I would steer away from the V-trim. I've read about too many having severe surge issues leading to short turbo life.

Keep your turbo, and get some Cams!



My evoIII pulled very hard with 272s!


I never cared for the T28 since I have a 1G, so I never looked into them at all so if its anything like the Nissans T28....It will like 264s over the 272s from what ive scene on dyno graphs...

But again im not familair with the dsm T28

 

[JOEY A]

Get it tuned and setup the car right, and you will be shocked at how well it runs


Think about this, if you cant even have the current setup running the way it should why are you going to try somthing bigger? Makes no sense, alot of dsm guys forget how fast they can go with the smaller turbos since bigger is cooler...


Yet there are 50trim guys on here, that cant touch some of the 16G 1/4 mile times but they still put down the small turbo..

Add meth injection! It will save you money in the pocket since race gas is pricey it will pay it self off...

Already mentioned, but I also strongly suggest the FP 17lb actuator. Makes a huge difference, absolutley worth the $99.

 

[eclipse_turbo97]

I saw the fp 17psi actuator, but didn't know if it would be worth it. Does anyone happen to know anything about the sbr gt11 or gt10 turbos.

I am personally VERY impressed with this post. I wish there was a way for everyone to read this.

I second this post, and that's my .02

he made a good point. I have saw some badass 16g's out there.

You have a number of good mods. You're most of the way there. Injectors, DSMlink, and a wideband will net you big gains.

You have a 95, it's likely you already have an EPROM ECU.
