250 wheek hp
 
what is it going to take to get 250 hp power to the wheels of my 87 turbo II. i have a 2.5 inch rb dp and i think it has a fuel cut defenser( how can i tell?) my budget is about 2.5k - 3k.
thanks guys

fmic, fuel controller, upgrade rad, hybrid turbo, e-fan, more fuel.

superstock2 04-19-04 01:04 AM

cool anyone else

rebuild with streetport : 1200-2000
Hybrid turbo: 500-800ish
720 CC injectors: 400-500
AFC: 300
Full exhaust from the DP back: 500
Walbro 255: 100
Intake, manual boost controller, boost gauge: 200? you can peice this stuff together.

remove emissions etc...

Get the rebuild for reliability at 250hp, a tired engine won't respond well to upgrades. The fresher the parts are the more reliability you are going to see from the car. The fuel needs to be brought up when you raise the boost in the car.

F1blueRx7 04-19-04 01:08 AM

agreed with the FMIC as well

superstock2 04-19-04 01:08 AM

engine only has about 30k on it jspec rebuilt

superstock2 04-19-04 01:11 AM

thanks guys i'm setting up the car for drifting so reliabilty is a must and power isn't but i also want a semi fast car! this is very helpful

First thing is you don't need an E-fan. There are countless debates on this.~$0

Secondly, You will need to upgrade fuel system, i.e 720cc injectors and a Walbro or FD fuel pump. ~$250

Thirdly, The racing beat turbo exhaust is your best bet. Racingbeat.com under exhaust. ~$780

Fourthly, FMIC. Greddy makes a great one for the FC. I don't have a link to a vendor for this, but it is a great buy. ~$700

Fifthly, a streetported, rebuilt motor. Rotary Ressurection (spelling) has great prices. ~$1400

That should easily put you into your power needs.

You may want a Haltech system also.

Lastly, all JSpec motors have about 30k on them. It was most likely not rebuilt, but came with those original miles.

EDIT: FMIC on rx7store.net for $975

where can u find an fmic for 700?

Rookie84 04-19-04 07:54 AM

You don't really need FMIC for 250rwhp. I'm running around 290rwhp on stock TMIC.

hondahater 04-19-04 08:03 AM

Yeah I agree that alot of what is said is not needed to make that much power. you could probably get close to if not the hole 250rwhp buy

1. intake
2. full turbo back exhaust
3. safc
4. 720cc secondaries
5. fcd (fuel cut defence)
6. manual or electric boost controller.

You don't need to port your engine to get that kind of hp but it would be nice if you want like 300+.

If you build your own, you can do it for well under $700. I'm designing an FMIC kit right now, but it will not be ready for production for a couple of months (money is tight).

However, the intercooler design IS done, and in about two weeks, you should be able to contact my supplier directly, ask for the intercooler i had designed for the 2nd gen, and get it shipped to you for about 320 bucks total.

You'll have to fabricate you own pipe work, and buy the silicone couplers, but you should be able to do that for less than $380!


HOWEVER, for 250 HP, i tend to agree that the stock TMIC should be ok as long as you tune the fuel in well and don't do a lot of stop and go driving where the intercooler will heatsoak.

Bukwild 04-19-04 08:16 AM

TMIC on a hot day will be useless. here in the colder months you are getting away with it but in 3 weeks you won't

superstock2 04-19-04 06:01 PM

anyone have any opinions on the apex'i GT exhaust remember people emissions aren't a factor

CRXtoRX7 04-19-04 08:47 PM

this is one way to get 250 hp.

Falcoms 04-19-04 09:07 PM

What if I wanted to get 250 RWH in an N/A? any idea how to do this?

look at your pressure sensor by the intake, if theres a box coming off of it, you probably have a FCD.

I've got a couple extra ones if you're interested. (Send a PM)

sell your car and buy a turbo

You misunderstand, I want to keep it N/A. I am opposed to the use of turbo and supercharging in this case. All I want is sheer hp out of the engine.

Ocelot 04-19-04 10:31 PM

In that case, buy yourself a v8 to put in.

no, YOU obviously misunderstand. ;) if its even possible to get that much power out of an N/A(2 rotor), you're going to need to get some higher compression racing rotors, do some MONSTER porting, and mod everything else so it can go to like 13k rpm :D

in this case, the motor won't even be remotly reliable, and will have NO low end torque.
