well today i got to drive a s5 turbo 2 and i was very unimpressed very. it had mild mods intake exhaust rtek ground control coil overs and newwly rebuild street ported motor ect

but coming form my s4 na it really sucked in my opinion one part i did like was the little bit of pull when the turbo finally spooled up but really it was not what i expected.

in the na world boost is like the holy grail that seems to be out of reach for me any way but i see now i am not missing much at all

and this is not to knok the turbo guys it is just saying that you guys have deep pockets becuase the car i drove had twice as much money in it than mine

side note the first thing i noticed about the car was how soft it was compared to mine which has solid motor and tranny mounts racing beatdiff mount and pinon snubber on tanabes with kyb gr2's which tells me suspension parts are well worth the money any day

the first time I drove a T2 it was a bit disappointing, or at least not what I expected. Coming from a 172rwhp nonturbo GTU, where you can take it to 5-6k and get instant (although less) power, the boost seems a little weird. Since the stock FC turbo runs out of breath at 5k, a T2 on stock turbo with the boost cranked up almost feels like a more modern DOHC V6. At stockish boost a T2 feels a lot like an n/a 3000GT in terms of the straight line power.

When you put a bigger turbo on there it's a whole new ballgame. Once you get something that can hold 15+psi to redline with more efficiency and higher flow it feels like a different car. On my old motor I went from 12psi on a stock turbo to 21psi with race fuel on a T04S turbo. Now that's a world of difference.

thats why you dont see a bunch of stock turbo cars. mine stayed stock for about a week, then i got a stand alone and an exhaust, then i tore all that **** off, got a 67mm turbo, big injectors, 4 inch exhaust and put 397 down on 1 bar. you should try driving a 400whp rx7 on street tires, its awesome, just be ready for that second to third on the highway.

i had at most 4k in my set-up, so it doesnt cost a lot of money, just desire to have a fast car and not listen to people who say it cant be done but have never even tried. there are so many people that tell you have to upgrade or this will never work after this amount of power. i put down 397 on the stock compression tube or throttle body inlet or whatever the hell its called. it was probably a restriction but it worked. all my intercooler piping was 2.25" swing set pipe that i hacked up and welded together. i have no idea why i just wrote all of this, totally off topic.

the car probably wasn't running properly or didn't have the boost turned up.

i think you were expecting more than whats really there. a ported however big motor with whatever standalone/piggy back is usless when u have a baby *** twenty year old turbo

alot of people get their cars running decent and think it should make its max power, you'd be surprised at the differance when everything is workin perfect with a proper tune, ive taken my car from a 14.0 to consistant low 12's in a car i daily drive 7 months outta the year

i have just under 6k cdn into my car includin the cost of the chassis and paint made 313whp and 289ft-lbs last year should be around 350whp now best 1/4 was 12.11@116.5 should run high 11's it ran 12.1' the last 3 weeks in a row blowin the tires off 1st and second [bald DR's 225/45r17's]
im goin back to the dyno in a few weeks......all on a s5 hybrid turbo with a KS chipped ecu and afc neo lol

The stock turbo doesn't run out of breath at 5K. I pull harder after 4.5K all the way to redline.

I drove an NA S4 for nearly 2 years. Then finally I found my dream car on craigslist... an 89 TII.

The car had decent mods, rebuilt engine etc... yet, for some reason I was disappointed in it. After driving it for a few months and thinking long and hard about it, I came to realize that I have more fun in my slow beat up $500 S4 than I did in my nice fast expensive S5 TII.

maybe its just me.

I drove my NA for 60,000 miles and then boosted it. It is a world of a difference...if that car was running with a maxed out stock turbo (10-12psi) there was either something seriously wrong with it or you are on crack if you didn't feel a major difference. We're talking over 100whp here.

Even besides the acceleration, the pull at part throttle is much better and makes the car easier to drive around town. Note though that a lot of rotary cars generally don't feel fast, maybe you were expecting the throw you back into the seat thing as soon as you hit the gas like piston engines.

Yup, boost is great but our stock turbo is really a pile of ****. How much boost was the car pushing? And when did it hit full boost? btw you won't have to wait for the turbo to "finally spool" if you boost your NA

I think you guys are just trying to make yourselves feel better that you wasted money starting with an n/a. It was like dreams come true when I did my T2 swap. Granted when I converted the car back to n/a it was still fun to drive but nothing compared to the T2.

Many of these cars, even the ported and modded ones, simply aren't running correctly. Who is to say how the car was tuned? Many people tune turbo RX-7s to ridiculously rich ratios which puts low end power and turbo response in the toilet.

The stock turbo isn't that great, but a street ported engine running the stock turbo at around 12 PSI (maxed out) is good for 250 RWHP, which is fairly significant. True, boost will taper down a bit as engine speed increases, especially with a street port. But the midrange and high end gains even with the "crappy" stock turbo blow the NA out of the water.

I think there was something wrong with the car you were driving.

Well I think what he means is the initial lack of power until you hit boost, and this is where do you alot of your driving at is under 3k rpm. You drive it and your like, **** this thing sucks. Then WHOOOOOOOSH.

I drove a beat up s4 t2 for about a week with the rear brakes locked up and it was still fun as **** and fast as hell. AT FIRST, yeah it sucked because I am used to more initial power, that is just the low compression rotors.

Most people don't have the cohones to give respect to things they can't have or get. Usually people find reasons to hate them or put them down to make themselves feel better about what they do have.

Its more of a function of humanity then a function of your friend's shittily tuned TII.

In many cases it is the rich ratios that hurt boost response. The stock ECU hammers fuel into the car under boost. Bring the fuel down to a sane level and the "below 3000RPM" issue becomes a linear power increase to redline. Then again, it's not like NA rotarys have a huge amount of grunt at low RPMs either.

Get into a big turbo and things are different. My car makes more torque at 2000 RPM then an NA 13B makes period.

The stock turbo should be making boost at 2000rpm anyways, which is more to say than an NA can do, so I fail to see the point.

Somebody needs to tune that T2!!!!!!

My turbo GTUs ran crappy during the week I had it, my 88 N/a was faster then it lol. After a quick street tune there is a HUGE difference in speed.

wow lots of replys

ok i just want to say i am not hating at all
i know the a turbo 7 would be scary and fun to drive i was just expecting too much i think

and now that arron cake said it the car was running very rich lol

i guess i am just use to the instant power of my slow NA but like i said my car has a soild drivetrain and new bushings that plays a big part in feel of the car to

but i am glad to see that i am not alone that a couple of people think that coming from a na to a turbo

I felt the same way about my s5 t2. the problem was the stock EBC wasn't working. after that was fixed the car was a whole new animal.

in my street ported s4 t2 i was getting into boost at 2K rpm, would throw you back in the seat good by 3K. was a bit choked at high rpm. but still making alot more power then an na

na doesnt exactly have much low end power, u gotta wrap them out to really get into the sweet spot.

my guess is sometghin is wrong with that car...

i will say going from a na with full exhuast and intake, to a bone stock high milage t2, was a bit disapointing lol. it was deff faster, but not amazing at all... but u do exhaust, intake, rtek and fuel pump and the car becomes alot faster!

When I first got my '87 TII I was disappointed and thought it felt slow compared to my '86 base. There was no wheelspin, chirps or anything and the low end felt a little limp.

After checking my speedo on a few onramps though it was MUCH faster than the NA.

Limited slip differential, 200 treadwear tires provided actual traction and so cut out all drama accelerating.

The fact that it made 2X the power at 3,000rpm (as turbo cars do) made the only 50% more than NA power below 3,000rpm feel kinda slow.

This coupled with the fact that with the soft tip in power of the low comp rotors and the smooth power increase of the stock turbo as it spools power comes on smooth and sneaky with a stock turbo.

Aso very quiet car like stock TII cuts the feeling of mad powa.

I am not saying this is the case with all TII, just my own personal experience.
