If I have an S4 T2, what's the safest and easiest, plus most cost efficient way to get about 250 rwhp. Keep in mind I'm a college student so I don't have a lot of money.


Thanks

 

Port waste gate
boost controller
FCD
full Racing Beat turbo back or Corksport turboback exhaust system
TID
BOV
FMIC
koyo radiator
720cc secondary injectors
fuel computer of your choice
and a wheel of cheese

 

good info, but you can do it for a little cheaper

any turbo back exhaust that is 2.5-3.5 inch piping will work.
delete the BOV, just use the stock one.
for this power level, the radiator is a good idea, but not absolutely necessary.

You don't need a BOV (100), FMIC (700), or radiator (300). That about cuts the price in half.

What you will need is a fuel pump.

 

V8

 

V8 is not the most cost efficient way to get 250rwhp.

 

it might be if you want 250 rwhp AND 250 retq, peak tq around 3500-4000 rpm with a steep fall off of course

 

So the thing that is giving me more HP is more boost or what?

 

That and better flow..

and V8? eww... pistons~

 

Essentially it boils down to more fuel and more air. Fuel pump and 720cc secondaries give you more fuel. Exhaust lets your turbo boost more, so you're getting more air. Then fuel & boost controller to give you the correct ratio of fuel and air for optimal power.

 

Thanks for explaining it Gingenhagen, I'm sort of a noob to turbo.

 

If I was going for 250, RELIABLE, My mods would go in this order.

Cone filter, with cold air box
Removed emissions(for ease of mod application)
Full turbo-back exhaust (Personally, I'd go with Corksport. <3)
720cc secondaries+Fuel controller
FD / Walboro 255 fuel pump
Boost controller - teamed with a boost gauge, and A/F gauge

That right there should be plenty. But as far as the RELIABILITY goes, slap on a Koyo, Fluidyne, or Mazdacomp radiator. Use the stock fan, or something big like the Vintage Air 3700 CFM e-fan. FD ALTERNATOR, if you go with an E-Fan. For a little extra air, you could tap a hole thru you're front bumper, or in the brake air-duct area, lead up into you're custom fabbed cold-air box. That is reliability.

If you want to be cheap, a.k.a. college student, do not try to reach reliability, AND horsepower. Power+Reliability = 2x Money spent.

 

You can't do it.
Speed cost money.
Cheap bites you in the ***.

Well said Ted.

Your best bet is to buy the parts one-by-one, starting with the exhaust, then intake. Buy the best of each that you can afford. The improvements will be incremental, but you won't be disappointed when you reach your goal.

 

- get straight pipe from the turbo-back (get an exhaust shop to do it), and get a CHEAP and BIG e-bay muffler
- build a Megasquirt standalone EMS
- get a used FMIC off a Volvo, and do the intercooler plumbing
- get a Walboro fuel pump, 255 is fine
- upgrade injectors (secondary)
- turn up boost

there ya go, should work decent and you won't spend more than $1500 or so. it WILL take lots of time though, especially with the megasquirt.

 

oh bullshit. its not how much money you spend, its how well you spend it and how good a mechanic you are.

i've spent less than 6k on performance parts for my car, and i'm expecting to run low to mid 11s with it. thats more like 450 hp. this is my daily driver. it is one of the more reliable cars ive owned.

for 250 hp, you can do it for under 1k, if you do it right and find good deals on parts.

Okay, let me qualify what I said...

I am *assuming* you have zero resources and skills.
Thus, all parts need to be bought, or you need to pay someone else to fabricate it for you.
This the fabrication labor needs to be factored in.

The original poster did not mention anything about friends helping him out, or if he has access to such resources.

All he mentioned is that he's a poor college student.
Most college students don't know jack about the automotive industry.

Yet, Ted, you never know when a college student is another FelixWankel88 Like meeee hahaha

 

i'm a university student, and i for one can say that MONEY and TIME are limiting factors for me, NOT knowledge about how the car works.
but still all my extra time and money goes into it...

 

thank god some do. the car scene around me is dying. no one wants to modify cars around here anymore it seems.


but that is beside the point.

 

i guess i was right in my post, except for listing expensive stuffs.

For your information on how to get 250HP safely and quickly. Go TED.

 

I dont think you can reach 250hp at the wheel with the stock turbo.

 

oh why didnt the previous owner of my turbo follow that.

 

its very possible
