horsepower goal

[Norcalmav23]

stock is 200 so im shooting for 250... Im thinking intake, header, exhaust, and chip.... fingers are crossed

[Asterisked Accolade]

I'm just looking to have a P2WR of 10.0 or less. So mine would be 250-300hp and I would lighten the car up to 2,550-2600lbs. Even less if possible (preferably 2,500lbs even).

Wait, aren't all cars distributorless ignition these days?

pretty ambitious to target 10 or less...

My experience..its pretty easy to throw around numbers, but when you start to get to the nitty gritty and start modding...things start to get hazy. Then you start fighting with yourself about feeling and compromise rather than doing whats necessary for a p:w ratio of 10. By then you've turned your beloved car into a monster, and as much as we love a beast of a machine..you cant really fall inlove with it anymore.

im pretty sure they are... at least in areas that are not 3rd world countries

250hp @ 2,600lbs is 10.4. That doesn't seem crazy ambitious to me. My preferred goal would be 275hp @ 2,550lbs for 9.3.

My Celica is being modded to be close to that-- hopefully 240hp @ 2,350lbs for 9.8. I don't feel like i wont love it anymore-- it's my first car and i'm making it into a car i can take to HPDS, not some kind of Frankenstein Nurburgring Beast.

I'm hoping somewhere around 200-230 whp with a super charger + i/h/e + tuen to keep things linear.

The car will take a header without a tune no problem.

the catless header has done 60 miles so far without a CEL as well. I'm planning on road testing that for a while and seeing if any CELs pop up over time.

oh and. my goals are 200~ whp. I think that would be perfect for this car without disturbing the balance too much. Plus... I'm pretty close to those goals already.
(I already did the high horsepower thing with my WRX. it's really not that much fun after a few years, once you realize it makes the car really boring on the streets)

My goal is +0 HP. I just want to keep the car as clean and stock as possible for as long as I have it. For aesthetics, I might add some of the dealer approved intake/exhaust parts if they provide a more rich engine sound (nothing too loud or obnoxious). I can't help feeling that I'd just ruin this car if I equip it with a turbocharger, mess with the tune, or build the motor etc

Maybe I'll wait to see what higher performance versions they produce over the years. I honestly wish I had two of these cars. This one to keep stock, and the other to make a project out of. I guess that's what my MR2 is for, heh.

well lets take your goal... to me...we can search for that extra 50hp..and think thats pretty easy 250hp is doable..

but in reality, im looking at finding 90whp to get to the 250hp goal. getting almost 100hp (90whp) additional out of a 2.0 4cylinder in the past has been pretty ambitious..and even required some engine builders to compromise streetability for performance.

then we have the chassis. Now this car is not exactly heavy. Sure we think 2800lbs is nothing new and its considered light for most modern production cars, my rx7 was 2700lbs and I felt it wasn't as nimble as the FRS around corners. If you take 200-300lbs off the Zx6 chassis, we really start to sacrifice that level of comfort we associate with a well balanced factory sports car. Taking off rear seats + factory seats, sound deadening, removing metal from the chassis, lighter wheels, etc,, by the time we reach 200-300lbs..you might as well strip the car down bare because its no longer that comfortable for street application...

At this point you look at all the stuff you have done...you have a monster...all that work and effort. only to catch up to a modded 350z in performance (in terms of numbers)...while the 350z might even still be more comfortable to drive.

Ok let me rephrase that . If you change the header you run the risk of running lean and blowing your motor unless a tune is put on the car to match the system

200whp

[uspspro]

Looking to get around 200whp with I/H/E/tune.

Then I will see if adding a Rotrex SC is in the cards at a later point in time.

If it will result in >250whp I will probably go for it.

[Kwaziekeller]

Well I'm coming from a 500whp Charger SRT8 (497 sae and 4200+lbs, around 8.4lbs:hp) so simple numbers wise, I'm after about 300whp in my FR-S to be in the same ballpark.. I'm aware that's not as easy as it sounds... but the gearing in the FR-S is much better for acceleration than the top end of the SRT8.

In the meantime, I'm thinking intake, axle-back and a tune. Should give me enough grunt to evoke more SPG and reduce restrictions to raise MPG as well. Will wait on header and over/downpipe until I decide if I want to go turbo/sc or both. Seeing as I had about 7k into my SRT4, and 9k into my SRT8, this car should get about 10-11k invested before I'm ready to part with it, but then again... I went from a 21k car to a 40k car and back to a 26k car so who knows.
