I've driven both the '05 Evo 8 (not RS or MR) and the new '06 Evo 9 MR and i just love that feeling of the boost kicking in.

Long story short, i wanted to turbo, parents shot me down, wanted to get a bike, parents shot me down, argued with parents, parents said they were more comfortable with turbo than a bike. And no my parents arent paying for this, but they have a say in what i do considering im in college and they do pay for a lot of that.

So after researching all the kits i really am set on the Turbonetics ST kit for it's price, ease of installation, ease of use out of the box, and ease of upgrades down the road.

I heard someone mention on the forums that the boost kicks in like a supercharger, so it's more of a mellow, gradual pressure on the car than a violent change in power. I WANT THE VIOLENT CHANGE haha. So is it true and im not going to get that turbo rush like the Evo or is it as i suspect and it's going to actually be an even bigger rush.

 

You've got the right kit if that's what you're after. From what I've experienced, the Turbonetics ST kicks the hardest out of all the out-of-the-box kits for the Z. By feeling like a supercharger, well, maybe if you're referring to a roots blower (stillen). It's not quite the same, but the turbo continues to build power throughout the powerband.

I'd suggest contacting someone for a ride. I know there are a few people in the San Diego area that would probably be willing to give you one.

 

Funny you compare an EVO to what you want to feel in the Z, I drove/ragged an Evo last summer and LOVED the way power came on, 3 days later I ordered the TN kit. The power starts coming on hard at 3500rpm's by 4000rpm's your in that fat midrange TQ and off to redline. I dont know about violent but boost hits and your in the seat. Funny seeing non car people ride in the Z, I hit it and they all love it. You'll be happy with the TN kit.

 

+1....

 

Good stuff, now i just need more money haha

 

the EVO being AWD though is made for traction

the Z is going to need a reasonably serious tire setup to get good traction

 

We all know this and it has nothing to do with the way the powerband feels

 

I've wanted to go F/I since i bought my car two years ago. My mods i have on the car right now are perfect - JWT Clutch/Flywheel & ADR M-Sports 18x8.5F, 18x9.5R with Toyo T1-S's all around. I took off all my other N/A mods i used to have.

I drove an STI yesterday and it was fun - great car for what it is. I noticed though that in the upper rpms like 5000-7000 it's kinda sluggish or flat compared to the 3000-5000 rpm range. I looked up the dyno curves that they do and it started making sense why it was that way.

 

My friends 400whp supra feels even harder. I dont know why but his boost comes on only between 4800-5100 RPM. Over 300 rpm he builds 16psi and gains 260 torque. u can't imagine how it feels. It feels like he gunned it when he actually gave it 100% throttle like 5 seconds ago lol.

edit: before any one goes newbbbb TT's supra can have 400 rwhp stock NEWWBB...
he has a fully restored MK2 supra w/ full stock body and MK3 race motor w/ T60-1 ST on MK3 tranny. 1985 celicasupra...
Itll keep pulling from 4000 to 9000 rpm where it hits redline

When i drove the evo i felt the power was pretty nice. It didnt feel like a brick wall. But then again, im used to my friends car.

I rode in a RX7 FD3S(owned by the same friend's brother)w/ a GT....35r?? I think... it had full boost at 2000RPM which was insane. Hes pushing 425rwhp but his car is fully gutted.

 

with turbo Z's, when in high rpms where you're within the full boost range, how is the throttle lag? Like say you're cruising down the street at 5000 rpms at 30% throttle, then give it 100% throttle - does it instantly go or is there a split second delay before getting oomphed back into your seat?

I think the STI had a little bit of that but not much

 

If my friend's car is already in the right RPM, the turbo spins up in less than 1/4th of a second. 2nd gear at 4800 rpm throws me back like a v8 would. All in all i think laggy turbos are good.. Retains driveability, good gas mileage (matters now haha) and your out of boost unless you want to be.

 

Oooooohhh yeah ++++1

 

Would I be wrong to say the Evo Kicks you back harder because it's a small 2 liter at very high PSI, while a Z is higher displacement and on most turbo set ups very low PSi? You feel less lag in the z because it already has the Torque N/A. This is why it doesn't "feel" as fast.

 

Its been a while since I drove the EVO-they feel about the same, the EVO builds more boost and is less powerful (the one I drove-bolt-ons), the TN builds boost quicker and makes more power. Turbo's can be deceiving though, when I drove that EVO it felt soooo fast then I raced it and put it to shame NA lol...

 

haha true that about the turbos being decieving. 400hp NA vs 400hp turbo..the NA will beat it.

 

yeah for something like an EVO or STI, you're cruising around town at low rpms in a lower than normal compression ratio 4 cylinder engine in a car that weighs 3300+ lbs. So it's pretty slow. Then when you get on it, the car grips, becomes a beast, you get thrown back in your seat, and you're suddenly going WAY faster than before - it's the sudden change in power that you're feeling.

You drive a C6 corvette around and cruising around town you already have a lot of power available to you. When you floor it - you take off immediately right from the start and the torque stays more or less the same with only rising slightly in the mid rpms. As you go faster you're only thrown back in your seat a little more as the torque barely rises.

the turbo puts a sort of delay in the power delivery, then makes up for it later with way more power - and for that brief period of time, you experience a power level of what would normally be a MUCH higher powered car, then it starts dropping back down to a normal fast car as the torque drops

 

Sounds good to me.
