280-300 rwhp.

 

Wait upgrade Everything meaning what?
Full rebulid

Intake/ Exhaust?

Plz be more specific

and if your looking for max turbo power look at the Turbo Spec's thread at the top

 

280-300 rwhp.

i think that bit too high :eek4:

 

a mate of mine got to just shy of 265 using greddy front mount and wolf 3d. He hit AFM cut first then ran out of fuel at around 1.0bar

 

I mean upgrading everything imaginable except the turbo. Meaning...

intake/intake manifold/ throttle body
exhaust turbo manifold/ downpipe/ test pipe or high flow cat/ catback
Cams/ adjustable cam gears/ valve springs/ head work
Lightweight pistons/ con rods/ crank/ lightweight pulleys
Port & polish
fuel injectors/ fuel pump
Stock turbo running 14 psi
Anything that will increase horsepower.

At what horsepower range will you need a bigger turbo/ FMIC?

 

you would see 280

 

Why up the engine that far then leave the stock turbo?

worried about spool or something?

 

No, I just think it's common sense to do everything N/A wise first before F/I. If you do everything that is N/A first, and then a bigger turbo, you'll get more out of it. A better flowing exhaust will spool the stock turbo up faster right?

280?? All that and you only get a 60 horsepower gain? That sucks. I would imagine it to be more.

How much power would you get if you just increase to 14 psi on a completely stock engine?

 

280 might be high too. Thats why its stuiped to put all that money into a car and not upgrade the turbo.

 

:werd

 

a new scented air freshener and you might see another 15hp... if you've already upgraded the muffler bearings?

dont forget the stickers

50 each lol
j/k

Not saying I won't upgrade the turbo. Just want to know how much I can get out of it before I have to.

 

umm s14 internals are strong....Pick up Modified Mag's new one with the S15 Time Attack car on the cover....that car has like 400hp with stock internals (FMIC, full exhaust, turbo, tuning components) Stock internals....it was like .5sec off some super fast EVO or something on some race track haha (I know it is vague, but you get the point). Well there is no point in doing all that work to support that power unless you NEED 500+hp. And your 280hp number is so low because the turbo cant produce enough air to supply the motor. Change the turbo with that setup and you have a very fast car....

 

we all know the sr internals are strong but he asked how much power before a new turbo, with the mods you listed you will see 280. Then throw on a bigger turbo, and there you go!!

 

you are still gonna hit afm cut at around 280

 

I see. Say you upgrade with an Apexi AX53 turbo kit that uses the stock SMIC, along with those mods I listed, can you get a reliable 300+ rwhp and 300+ rwtq?

 

stock smic with that turbo...can you say explosion haha. but seriously these questions are lame....upgrade your car so the components are limited equaly. Dont spend 4k on a built long block and then use the stock turbo manifold and turbo and intercooler and injectors and see hoe much power you can crank out. It is like saying "whats my best skidpad test if I do full suspension but have stock wheels and tires"

 

Would be the same idea as building a NA V8 so I don't know why it would be stupid. Get as much out of an engine first and then upgrade /add force induction.

HKS's GT Sport turbo upgrade kit merely replaces the stock turbo, how much power would that make??

 

its not a v8 its a 4 banger. You make power from a turbo not a built engine. Do basic mods first then worry about it. Basic being full 3in exhaust, fmic, bigger injector, something to tune, boost controler, fpr, and a bigger fuel pump like a walmart 255.

 

Not trying to be a dick or anything but have any of you guys actually done all those mods I listed?

 

No...thats the point. Your building a 800hp motor. But you insist on using (or asking) for the amount of power the s14 t28 can produce. Its nothing like building a N/A V8. The way to get more power is simple...MORE AIR and MORE FUEL.....thats it. If you cant get the volume of air smashed into the cylinders, your just limiting your motor by turbo. (n/a v8's use high high high compression pistons and there strokes are HUGE so they get massive amounts of air and then compress it ALOT. thats totally different from the sr20, its a 4 banger with equal stroke to bore so it has roughly the same amount of trq. and hp. instead of high compression pistons we use TURBO and the bigger the turbo the more air.)

Before you ask the questions so you can go to your car buddies and say "ohh yea my car can make 280hp on the stock turbo!" ask yourself what your going to use the car for. Ask if you can be responsible, and what your budget is. Most think they have 4k to drop on the motor alone but that will get you basic bolt ons. What you want is a SERIOUS project. Dont est. pricing and parts alone, tuning is alot and other little things cost money.

 

Lets build an engine and then murder the turbo causing it to throw nice shavings of metal into the rest of the engine and the oil, good idea.

It's not that simple. To make the most of the turbo's potential you'll need a front mount intercooler, full 3" exhaust, upgraded fuel pump, bigger injectors, z32 mafs, a boost controller, some sort of fuel management and dyno tuning for starters. I'm tired so I probably missed an item or two.

Not really trying to build an 800hp motor. Just trying to get maximum FLOW. It's not just all about how much you can cram in but how fast it enters and exits. The basic concept of increasing power is increasing fuel AND FLOW. Say I just get a bigger turbo, FMIC, intake pipe/ filter and cat back. That probably wouldn't get you past 300 because you don't have maximum flow to begin with. I was looking at the "Getting my car tuned..." thread and noticed that he didn't really gain that much out of it. If he did intake mani, throttle body, cams/ cam gears, valves, head work, pulley, etc he would have gotten a better result.

Tell me, is it not common sense to maximize flow first before you add more air/fuel? If you add more air/fuel first, you're not going to gain much because there is still a restriction. The restriction is going to be even worse because you're trying to push more out of the same given space.
