is it realistic????

[skemp45]

is it realistic to make 350-400hp running a 16g? i know i can but is it realestic to run a 20g as a street car?

 

[skemp45]

whos going to buy a blowen up 420a though and i liek the 420a because noone else does them and i cant seem to find a desent gsx for under 5000

 

[frankozz]

Gsx shell + 6 bolt and other needed stuff is less than 5000.

Build whatever car you want with whatever motor dude. You have had all Turbo guys respond to your question. There are plenty of N/T guys with turbo's doing nasty things. And loss of traction is part of the game. Talk to the people who have done it, not the people who skipped it and bet on the winning horse (4g63).

thanks reclipsergst and thanks everyone else i am doing a 420a build ive been around dsms long enough to know that its more expensive and harder to do a 420a but i like that challange and being the odd guy out

is the 20g over kill and im getting the turbo ported and clipped if i get the 16g is that a good idea?

There are more turbos out there what what Hahn makes for the 420A.

A couple things to remember:

- Hahn 16G & 20G turbos have T3 turbine housings. No need to port something that is already too large for most street-driven 4-cylinders.

- Most of the manifolds available for your car have a T3 flange, meaning your turbo choices are endless. You can run something as small as the stock turbo from a Mercedes to a HTA3586R.

- Don't come here asking what a particular turbo can make when it's maxed out. Give us a total horsepower number you'd like to make, and we can recommend a turbo that will get you there if you do not understand how to read compressor maps or translate airflow numbers into horsepower.

- Keep in mind that more horsepower requires a bigger turbo, and a bigger turbo adds lag....there's no way around that. You're not going to have a 500whp car that spools like a 16G-powered car.

You're not going to have a 500whp car that spools like a 16G-powered car.

And you're not going to want one in a fwd car.

thank you for that and my numbers i want are anyware close to 400 and my engine is going to be completley built wiith 8:8:1 compression so noone needs to say i need to make sure my motor is built it is and it is strong

Rock a holset.

I had one on a ford focus and much to my own surprise for how big it was it spooled up much quicker then you would think. Not to mention the damn thing can make god awful amounts of boost, they are cheap and easy to rebuild, and they are usually had pretty cheap for what they are.

Not to mention the flange is a t3/t4 can't remember which one so it will fit most any aftermarket manifold.

Like the other guy said if you want to make big power especially on FWD lag can be a great help to you on the streets as it will let you get going before all hell breaks loose on your tires.

I ran 15lbs of boost before my for focus bit the dust hard, and when i took it to the track i ran a 12.5.

I made 301hp and 297tq. Which compared to stock was AMAZING. And the turbo itself had ALOT let in it.

Add to the fact your spending 3k in fuel and 4k in the motor for a forged setup. It IMHO would be the best bang for the buck and give you your goal and then some if you decide to get greedy.

Wow, you weren't even CLOSE to the compressor efficiency of that turbo and still put down some impressive numbers at the track.

You would've been better off with a turbo that was a little closer to it's peak at 15psi....something like a Small 16G. It would've shaved some of the spool time off as well, making the car more fun to drive on the street.

Was this done on stock internals?

I run my 20G daily on the street.

I also pushed near 370 AWHP on my evo III 16G
