350HP - cheapest wait to get there?
 
Basically, what is the cheapest way to get 350hp out of a Turbo II FC safely? I was thinking custom 3" exhaust from the turbo back, HKS T04 turbo manifold, T04 turbo, TurboXS manual boost controller, FC controller, walbro 255 fuel pump, guages, and a custom front mount intercooler.

What do you guys think, also how much would this cost around with the custom work?

I know this has probably been asked before in other variations so I apologize if it has - I guess I'm just looking for a 350hp recipe that's totally affordable (even if done one thing at a time)

Also, about what kind of time could I expect with 350hp in the FC?

Am I missing something here? (newbie to rotarys)

the cheapest way to get 350HP?

well someone had to say it so i will....

LOTS of stickers and a super XXXOS wing on the back.

LOL...don't forget the NAAWWWWWSSSS!!!
j/k.

I'd actually like to know this too. well more exact would be to get 300-350hp and keep it street legal (in california) if possible.

If your thinking Power FC for a EMS, think again. They only work on FDs here in the states. A different option would be wolf/haltech/etc.

You also forgot the wastegate, bigger injectors, and oil and coolant lines to the turbo. There's more, but I have to goto work now...

75 shot of nitrous and a little more boost and fuel will get you up there safely. I dont know about 350rwhp, but the nitrous will cool your intake temps, which should prove handy on a turbo, also, it'll boost your low end power which the rotary engines dont have.

You are on the right track but I think you should think of what's the combonation will be the safe. If you cut corners it will end up costing you more in the long run.;)

Really, if you wanna play, you gotta pay.

You're looking at a minimum of -

- Full exhaust
- Intake
- Intercooler
- Larger turbo (*maybe* a hybrid, but likely a full T04 on an HKS manifold)
- LOTS of fuel
- Fuel management
- Boost control
- Blow-off valve
- Upgraded clutch
- Complement of gauges

That's just to begin with. On the cheap side, buying things used and fabbing stuff, maybe $3000.

That also doesn't factor in the rest of the car - making 350hp in a car with blown-out stock suspension and poor brakes is a REALLY bad idea. Add to that some good quality tires so you can actually get traction, too.

Also, do you think you can make 350hp on a tired, 120,000 mile motor? Nope. It's gonna give at some point.

You're also going to have numerous things go wrong - leaky radiator, worn water pump, new alternator/starter, clutch hydraulics, etc.

300-350hp to the ground is my goal with my current build-up, and I can tell you right now it's FAR from easy or cheap. You're going to spend many times the value of the car on the path - part of the problem is we're not dealing with new, low-mileage cars any more, and there's lots of things that need to be fixed.

Not to mention if I'm making that kind of horsepower, I don't want to pop my hood and have a dirty, cobbled-together Home Depot setup - that's just embarassing. A lot of the time in my buildup has gone towards cleaning and refinishing everything to make the car as close to new and as top quality as possible.

Vosko was running a Power FC on his FC...and he's in New Jersey :D

Exactly, which came from what country? ;)

Dale's is the proper way.

The cheapest way is a shitload of nitrous and extra fuel.

I could have sworn he was running a Panspeed ECU?

He is, or was, because I'm the one that sold it to him. :kicking myself in the ass:
That was when I was building up a FD... but I'm back to T2's again.

I've never been a big fan of nitrous - yes, it does work, but I want power ALL the time, not for as long as a bottle of nitrous lasts (which isn't that long!). Not to mention nitrous isn't the best for blasting up curvy on-ramps where you're steering with the throttle.

Yeah, probably the cheapest way would be a big wet nitrous setup. But, I would defininitely raise some reliability concerns. 350hp is fun, but you don't want to spend the money to experience it ONCE then hand-grenade the motor.

"Horsepower" and "Cheap" are inversely proportional to each other. I also stress the point I made about the other components in your car - having driven a 300+ horsepower FC for a while, you'd be surprised how much you need good suspension and brakes! With a car that can get into ludicrous speeds VERY quickly, you really need to be able to haul it down VERY quickly. I don't think the majority of the people on this forum have driven high-horsepower cars and fully understand and appreciate the whole picture.

i'm doing everything but the motor first. reliability then suspension brakes and tires

do the motor in a year or two. it can wait. it's better to be fast around a road corse and stop on a dime than haul ass down the strap strip and blow something up. at least this is my opinion.

RylAssassin 10-01-02 12:20 PM

you need 10 grand to get that kind of hp
good luck bro;)

with all that being said, what would you think it would take to get to 250 hp to the wheels? thats my current goal and i'm hoping i can get there safely with my 700 bucks with my current mods already done. what do you think?

would a boost controller, afc and catback do it?
$20 needle valve, $300 s-afc and $300 corksport catback

Add a front-mount intercooler, a Super-AFC, and 720's and you'll be there all day long. Opec did 242 to the ground pig rich on a super hot day, and is now making WAY more power with it tuned in right.
