Upgrades for reliable 300hp daily driver?

[iwalton]

Hey. I have a basically stock fwd 1990 tsi 6 bolt in a 1994 n/t body and I want to get more, reliable, horsepower for my daily driver. I have a 3 inch turbo back w/ cat delete and am currently running 17 psi on the 14b. Horsepower goals are around 300 whp. What would be some suggested upgrades and in what order would you do them?

If you want to stay pump, you can go 2g maf, evo 550s and max that 14b out at 21lbs. You can even stay on that side mount intercooler.

Can I stay on the stock fuel pump with 550's? What is the benefit of the 2g maf over the 1g?

You must upgrade to a walbro 190, that way you don't have to upgrade your fuel pressure regulator. The 1g maf maxes out much sooner than a 2g maf, but the reason you run a 2g maf, in a 1g, is the ecu over compensates and by running the 550s it evens out. That way you don't need any external tuning software. Even though dsmlink v3 is the best think you can spend $500 on.

Is there any benefit to going straight to the 255 pump, or is it just overkill? I've done a little reading and i've heard that unless you have an eprom kit (I don't), you can't use the 2g maf. Is that true? Why not go for a gm maf (and is the gm maf basically a bolt on and plug in?) ?

 

[TSi Kid]

I'm doing the cheapest for you. You can do a GM maf and a translator but it will run you about $150. A 2g maf is like $30. Then, all you need is a connector harness which is another $15-20.

The 255 is overkill, and by going with the 190 you don't need to upgrade any more of your fuel system.

A 190 is just fine, 255 and youll need a afpr another expense.

Which is exactly what I said several times. Thank you for copying and pasting.

The GM MAF has a different connector using 3 wires. What those wires are, not a clue since i was not the person that installed it.

 

[92AWDHX40]

Yep, i bought a 255 didnt need it, oh well, i didnt know any better at the time, learned a lesson on that one, look into a evo pump.

The benefit of using a 255 vs a 190 is that in the future if you want more fuel than the 190 and produce its avaible to you. I say go 255 and dont look back. the only downside to a 255 is that you will need an aftermarket fuel pressure regulator to compensate for the new high fuel pressure and flow.

I've done a little reading and i've heard that unless you have an eprom kit (I don't), you can't use the 2g maf. Is that true?
Did you hear this or read it? If you have heard it then that person is steering you in the wrong direction, if you heard you, I think you misread. 2g MAF is an upgrade from the 1g stock MAS. You will need to compensate for the new 2gMAS system, either Ecmlink or SAFC, just two examples of tuning solutions.

Eprom has nothing to do with what MAS system you use. Read up on what eprom is: epromid [ECMTuning - wiki]

Why not go for a gm maf (and is the gm maf basically a bolt on and plug in?)
You can go with a GM MAF, but I think you need to do more research on what the GM MAF is. It meters the air after the turbo. This will have a different tuning effect than the stock MAS systems or Speed Density.

GM MAF is not a bolt on and go. You will need a tuning solution, ECMlink or MAF-translator, touse the GM MAF.

Over all I would start doing more research into what everything is that you are talking about. Most of the answer are self explanatory.

255, with 550s is the correct way to go, as what the others said, go with the GM MAF with the maft

Sounds perfect, except that evo injectors are actually 560s, and they usually flow-test around 580-600cc. In other words try to pick up some RC 550s. Also you don't need to buy a 1g to 2g mas connector, you can just rewire it yourself, really easy - 2G MAF in a 1G TEL/GVR4

There is plenty of information, when you want to achieve that goal, lots on google, and this site. When you read more youll learn a lot about your objective.

Sorry you got mad that I corrected the misinformation you told the OP. I won't let it happen again, I'll just let him fvck his car up instead of calling you out.

Evo 3 injectors, the yellow tops, are 510s which is what I was referring to and what i've used when doing the 2g maf and evo injectors. So please tell me how this is misinformation and how his car is going to blow up again... oh wait. It's not.

I think he's referring to usdm evo (evo VIII-IX) injectors, which are not yellow top and are rated at 560...
not having a verbal debate on a post meant to help the OP would be awesome.

I know what he's referring to derp. My statement was still completely true, and non of which would "blow his car up".

Thank you for your unneeded post. OP you have all the info on here that you need for your build, any other questions feel free to PM me.

I even ran those evos before i sold them , they did a great job, again there are a lot of threads on, your goal. Sholuldnt be that hard to learn about what you need.

Looks like you said 550s to me, then you were corrected so you changed it and said you were talking about the 510s .... am I missing something here?

Eather way you will want something to tune with that will take all pain and leave you with ease to start out with.The theory of the 255 fuel pump being to big is different from every person as I have been running it like that for years without a afpr.It's up to you what you wanna do for your power goals just remember the smaller you get the more limited you will be.There is a walbro 190 or a walbro 255 or a evo 8/9 fuel pump.As for bigger injectors to reach your 300whp mark you can get a safc and run 650 but that would be it, trust me I had it for a week and got sick if it.Don't get me wrong it will work for what you want it to do but agian limiting your goals and well more money you will have to spend later if you wanna upgrade.Smartest of course as everyone knows is getting ecm(dsm)link for tuning as you can fine tune the car really well as also running just about any injector size you want for pump gas and money saving I would just jump to 1000cc's becuase all injectors are about the same price but for your goal I would get eather 750cc or 1000cc for link or 550cc or 650cc if running safc.As for your 14b sure run it 21psi see how long it last but also are running at 17psi with no mods I doubt its running right or even at that boost level.I would recommend a 16g of your choice, and that will get you close to your 300whp range, I think I picked up my last 16g for $125 bucks so hopefully this gives you an idea.First things first do all your maintanace if that's done get supporting mods that is your key for your car because I am sure you don't wanna have all this mad horsepower and well your truck is getting towed on a flat bed becuase of negleted stuff.Start with a wideband and boost gauge if have some of the following feel free to update your profile.Also you can throw in the fuel pump at anytime and from there decide how much money you wanna spend on injectors tuning software and possible 16g turbo upgrade.
