After more torque, is this the right mod?
I love the feeling of the sudden surge of power the car makes and I'm after more of that. While having more HP is great I'm after more torque... I was considering a CT20b turbo swap but reading mixed reviews so I think I'll pass on that... I found a part from racerx. They have this Center Feed Intake Manifold which apparently increase HP and torque (around 40HP and 30torque)...
Anyone have this or know anything about it? Is it worth it for gen 2 with just bolt on mods? The only draw back that I can see is that it moves the throttle body forward so new throttle cable is required

On a basic engine, you'd be better off getting the ST162 side-inlet manifold and using that. Will save you quite some coin. :)

What other mods are you running? I'm not sure you'd see that kind of increase on a stock build, notice they claim that kind of gain on average, most people installing one of these intakes have done a fair amount of other mods to the engine.

Your not going to see any massive increases like that on a relatively std motor/turbo/ecu combo.
Ct20b, gen3 injs and an ecu upgrade would be the next step forward short of rebuild with 5s bottom end base etc

With the added boost you'll definitely see a gain but I would guess not the full 40/30. If I were you I'd send Jeff at RacerX an email and ask him for an estimate of what he thinks you'd gain with your mods. I've found him to be pretty helpful in my dealings with him. Depending what he says you might find its not worth the money at this point. You could be better off putting the money into a turbo kit or ECU etc. petmr2

Are you refering to the Side Feed or the Centre Feed? If your worried about moving the TB forward not making it work I'm sure RacerX could make a TB inlet to make it fit. The stock one is restrictive anyway so your better off without it!

ok thanks guys for the reply... Looks like I'll give that mod a miss than... turbo upgrade sounds good but then I have to worry about all the supporting mod...
Do you think the ct20b is worth it then? From what I've read it's about 30hp increase but I'm not sure of torque figures... And when you say ecu upgrade do you mean like an aftermarket computer or using gen 3 ecu with ct20b?

Aftermarket ECU like a Power FC, Haltech or whatever the tuner you use likes. You'd be looking at around $1200-$1300 for the centre feed once you factor in the exchange rate and shipping. For $1200 you could pick up the GT2860 turbo kit thats in the For Sale section right now, $1500 and you get the fuel system too.
Admittedly you'd still need to save up a bit for the ECU but thats pretty good bang for your buck and will definitely give you what your after!

Yeah I noticed that turbo... Keen but yeah all the other supporting mods they start adding up quick... it's really amazing how much I've spent so far...

Its worth it though ;) Or thats what I keep telling myself!
Another thing to consider is the ct27 package from ATS. You get an upgraded turbo as well as a Rom tune so you have the benefits of a tune but get to keep your stock ECU. The ct27 performs as well as ct20b and you get a freshly built turbo instead of a used ct20b with a ceramic turbine of questionable reliability.

I personally wouldnt go a rebuilt hiflowed ct26 version. Its too limiting. Theres a high chance youll want more.
I'd go with an ecu upgrade first. Your old std ecu is hardly optimal and its only guessing if your running more than 12psi. If it knew you were running more, it'd engage safe mode.
The good thing with that turbo kit, is the tial ss housings have the same fitting pattern, so you could easily fit a gt30 series turbo with tial housing and it'll all bolt/vband straight up.
