10psi will net ya 220whp. The reason I mention 10psi is because ya can do that on the stock engine.

But with new rods and pistons you can easily hit the 400hp+ mark.

But anything over 300hp, wont be very streetable.

perhaps a engine swap would be best for you. since you do not know much about a turbo setup even if it can make tons of power.

 

With 10g's, drop in the motor out of a stock Mitsu VR4 Turbo and upgrade that... yum....

 

I'm going to poke my head in here real quick:

Building a block with 300-600WHP capacity would require the following (this is block ONLY)
2.0L block - $300-$1000 depending where you get it
Forged pistons - $550 with rings, pins, locks
Rods - $700 from Crower
Engine Rebuild kit - $250 Hyundai OEM gasket package
Machine work - $300-$500 depending on quality and labor rate
ARP studs - $250 as 2 of the 10 have to be custom made @ $50 each
Misc BS - $500 in other goofy parts you missed or stuff that didn't come with the block

Total expenditure on my block was $4100 (I used a few more exotic parts), Joel and I did all the labor. If you can't assemble a full longblock on your own, expect that cost to rise considerably... The block can now deal with 600+ wheel horsepower and not explode.

Then you need electronics:
Engine Management - $1100 USD for Haltech E6K and sensors
Laptop - $100-$300 if you don't have one, just need a cheapie 486/Pentium 1
Crank Trigger - $100 from SDS; stock Motronic sucks worse than I realized sad.gif
Plug wires - $90 for a set of Magnacore KV85's; you REQUIRE EMI/RFI suppression for the Haltech
Fuel pump - $110 for a 255lph hi-pressure pump
DC/AC Inverter - $60 for a good one so you can run the laptop all day

There's about $1500 in electronics, and I hope you like soldering irons and ripping the car down to the bare metal to replace the entire engine bay wiring harness. If that scares you, chalk up another $500 at LEAST for someone else to wire it for you. Then you'll need to program the E6K; time to buy a few books and start reading.

You now have a $5500 motor and computer system that makes stock horsepower and takes 8 minutes to warm up in the morning before you can drive it.

Time to force feed it:
Exhaust Manifold - $400 for cast iron, $1000+ for custom bent tubular
Wastegate - $200+ for a good Tial 35mm
Turbine - $675+ for a hybrid T3/T04e good for 400WHP. Add money for more WHP...
Intercooler - $500+ for a good Spearco core and endtanks
Piping - $350+ for all the mandrel bends, silicon grommets
Blowoff valve - $150+ for a decent one
Welding - $200+ if you can't do your own welding to tack IC on, charge pipes together, et al
FPR - $200+ for a good adjustable rising rate unit
Full exhaust - $600+ for a good 3" custom job with cat.
Misc - $200+ for oil lines, tapping the pan, seals, gaskets, grommets, stuff you missed

You now have a ~$7500 setup that transforms the stock differential into sand.

Clutch - $800+ for an HKS twin plate so it doesn't shell the flywheel
Differential - $1000+ from Quaife for the front diff of an AWD 2nd gen turbo Eclipse. Then you get to immediately void the warranty by cracking it open and flipping the pinion gears backwards to make it work on our cars.

Ok, we're at the $9500 mark... It makes 400+ wheel horsepower, it doesn't eat the stock tranny (well, just don't use 5th gear) and it doesn't get traction until 4th gear.

The rest of your money needs to go to MUCH larger brakes, wheels that fit over them, a full suspension upgrade to keep it on the pavement and a VERY good radar detector and jammer.

KEEP IN MIND
You guys have absolutely zero clue what 400 wheel horsepower means. If you dropped yourself into a 200WHP Tiburon, you would absolutely shyt yourselves. One of these cars making 300WHP is enough to run away from a Vette Z06 on the highway. One of these cars making 400+WHP is enough to run away from most 1100cc motorcycles on the highway. You will never have any traction from a launch, even at 300WHP the car will lose all traction just from punching it in 2nd gear.

The thrust-to-weight involved in a 2600 pound car with 4.xx final gearing and 400 horsepower on-tap is insane.

Don't automatically assume that a 250WHP car is somehow less than adequate.

Heh, Red, if that's what you call quick your girlfriend must be happy.

Red does have a point that most people overlook when dreaming of super-tuning. When you get to that point simply controlling the sucker is not for the faint of heart, good driving skills are a must.

If, as you said originally Shwa, you're looking for a sleeper, 250whp is enough to take anyone at your local strip driving any car that costs less than $40k. Getting above that point and you're reaching the territory of the sports cars--cars that have thousands of hours of design and tuning into the body, suspension, and braking to make them drivable with the power they have.

 

Yep, I did not wanna get specific but Red did, and he kicked all our asses while he was at it.

like I was saying before, obtain 240hp/300hp
and then we can work on more.

But as you can see, anything higher and you are looking at 8min warm ups.

 

thanks alot guys, that really does help alot. and gives me some really good ideas to work from.

 

So RB26DETT's 900+ Bhp out of my boss's car is somehow considered overkill?

 

I couldn't get traction on my Eclipse GSX until start of 3rd gear if I gun it.

<div class='quotetop'>QUOTE </div><div class='quotemain'>BoOm:

If so,

Then,

OMG HOW IN THE WORLD DOES YOUR BOSS DRIVE THAT THING???
