So I'm currently installing a set of 99 specs. I was thinking about switching to non-seq. while I'm under the hood; however, after reading some threads I am taking a second thought about that.

It seems to me that though you gain rwhp, you loose low end power. Is there a way to maintain the low end power while going non-seq.? I'm wanting 350rwhp out of my car for the time being; however, like any addiction I will need more later in order to settle the addiction twitch.

 

nope. keep em sequential. you'll thank me down the line. i put down 350 rwhp running 99s sequentially with supporting mods.

i get full boost by 2500 RPM. non-seq you are sitting around waiting till ~4000 RPM for boost.

lots of fun driving on the street with very quick throttle response.

 

What kind of mods do you have? Were did you get it tuned at?

Currently my set up is:
3" down pipe
3" mid pipe w/ resonators
apexi n1 exhaust
FC controller
apexi intake
boost cotroller

Is this good for 350? if not were should I go from here?

 

is the motor ported?

short list of flow mods: full exhaust, open intake, larger IC, 1300cc injectors, PFC, street ported motor, 99 twins, boost controller

why the fixation with 350?

 

The motor is stock. 117 in one housing and 115 in the other, so its still very strong.

As for the 350 goal. With 350 to the wheels with a 3k lb. car (including me) I will be able to break off the stupid guys in their Carreras that live by me. There’s one guy in particular that toys with me on El Camino Real. He has a Carrera S. I know its all in good fun, but it will be great to take down a car that has a price tag 4 times as much as mine. Yes I'm competitive.

 

Funny I run into this thread. I just randomly decided to search Non-Seq just to see about simplifying my engine bay a bit.

What type of power do you think I will be putting down at relatively stock boost levels 10 - 12psi max.

13B-rew rebuilt 2mm
Street port
99 spec twins
Full 3 inch turbo-back (Non resonated)
Air-Pump eliminated
Ported Waste gate
HKS Intakes
Apex'i Pfc (Hopefully)
NGK Plugs & Wires
Supra fuel pump

My goal is also 350rwhp as well...
