FI or Tune and Header?

[bfrank1972]

Is your car new? If so break it in first, it picks up some pep in the first few thousand miles. In those few thousand miles learn the car and get comfortable with how it behaves. Then go ahead and get your car tuned - OpenFlash, EcuTek, BRZEdit, or the new ECUFlash software coming out soon. Won't provide massive gains but will make your car feel more responsive overall, and will be necessary down the road if you go further with the mods.

Regarding the 'torque dip', just learn to drive around it - I drive in two 'modes'. One is just driving around mode where I upshift around 3500, which drops revs revs right back into the nice lower torque 'bump'. Mode 2 is 'fun' mode, I don't upshift before 5500, which would drop your revs to right at the upper edge of the torque dip.

BTW I used to own a 1973 911 S, still hate myself for selling it! Once you get comfortable with tossing it around, the FR-S is likely quicker than your 1969 (unless it's hot rodded) and definitely faster around the bends (especially with good performance tires instead of the factory rubber). Enjoy!

I guess you need to ask yourself is if ~185WHP is enough with full bolt on going N/A.

There is no denying going forced induction is going to be some good power.

At any rate a tune is necessary for whichever route you go and so is a header if you go with a supercharger.

If you go turbo you won't need the header by no accident.

Enjoy it! It's a really fun car!

Thanks, I agree completely, that's why I bought it. Those were my first four cars, none bought new and unfortunately each sold to buy the next one. If I hadn't been a teenager and could have salted them away I'd be retired now.

As much as I enjoyed them I have gotten somewhat spoiled in later years by the power of my M3's, my current 911, my 3rd gen RX7 twin turbo etc. Although I did retro when the Miata's first came out. I keep trying to remind myself that the 69' 911T had 125 HP and a 0-60 time of 9.6. Dang, it sure seemed faster than that. That's what a small light car will do for you.

Thanks for the advice, all good.

See above for my 911T, I looked up the specs. Maybe it seemed so fast because I was coming from the 96 HP 356.

why not go the headers and a header back with a flex fuel kit to run e85. There's been some really good looking torque output with these setups. Almost as good as some supercharges running 10 psi.

The best part about driving a car like this is that you actually have to 'work hard at it' to get the best out of the car. Heel-toeing corners just to keep to the power band, keeping best lines on the road to keep your momentum, lol.

Anyway, in N/A mode, the car is no slouch. Can get low 6's or even a flat 6 for 0-60mph/0-100km/hr with some work and a good launch.

Contemplate a full exhaust(EL headers,o-pipe/frontpipe,CBE) with a good cold air feed(HKS :P ) and K&N panel filter and a GOOD TUNE and you should be good to go.

I'm personally going to keep N/A as long as I can(hopefully there will more *more* N/A parts developed SOON). Nothing better than being able to beat on your car for a whole day at the track and not really worrying if the engine is going to CEL or grenade

You may be right but the list only went through 1970 to 77. Had a bit more muscle since then.

But as you can see from the above post on my 69 911, it is all weight and size and that is precisely why I bought the BRZ. During my lifetime almost every great sports car introduced grew in weight, size and horsepower until it became almost unrecognizable. That is true of my current 911 and also of my E36 M3 compared to my E46 M3. In my view they were not improvements.

We get 93 and I've always had premium fuel cars. I can't honestly say there is E85 around but there very well may be. I'll start looking.

i'd go fi. no need to piss around, just get it done. leaves more power on the table for when you inevitably get bored with it as is.

Drive it & enjoy it for at least 5-10k miles and then maybe make a choice? That'll give you plenty of time to get used to the car and figure out what you want out of it.

An innovate supercharger should fix all your torque needs, and at ~$3500 is a pretty good bargain. Only downside is I've heard lots of probs with people in high heat and/or 91 octane, because it doesn't have an intercooler.

Or you could do header + tune + drop in filter for ~$1500 and have a moderate boost in torque & power. This will also go well with the S/C.

Either way, this car is lots of fun and I'm sure you'll have a blast.

honestly, if i'm driving spiritedly i'm usually well above the dip in rpm's so the car has plenty to pull itself out of a corner.

you can always go header, and then ad FI down the line. there are a few good v-band headers on the market that make that possible. since you've driven cars with similar platforms i really don't suggest FI be your route to go, its plenty fun with suspension and a tune.

if you're local i'd be more then happy to meet up and show you what i'm on about.

I'm in NW South Carolina. Best i can tell i'm 10 hours from any of the vendors posting on this site.

[Jive Turkey]

well if you're ever in NJ shoot me a pm. i might be down that way come spring, but i'm not sure.

regardless if you're into driving this car with suspension and tires is a pure joy. can it use more power, sure...so can any other car. i love mine as is, idc that i can lose to everything in a straight line, it has plenty of power to over take people when needed and on track/auto-x/exit-entrance ramps/anything but a straight road not much will keep up.

the speed this car carries through turns will blow your mind. its a joy.

but honestly, everyone is different, buy it and drive it as is and see what you want to change.

MY MODIFIED 86 DETAILS
FUEL USED: United P100

Intake
- HKS Cold Air Feed(with 3x ducting holes cut out in front bumper)
- TRD USA Intake

I believe S/C will net you an easy 70 hp at least. Happy atm with my setup, will have to see how I go against the S/C guys on track day in the middle of summer in two months time

Don't forget your fuel is a much higher grade than we have access to. But great numbers
