16g 2.3 stroker street car setup

[Subie killer]

Hey I'm doing a 2.3 stroker with bc 272s, I have a fp exhaust manifold and a fp 16g with a ported exhaust housing. I'm wondering if anyone has done something like this setup before and if they could tell me what I might be able to expect for my power band. Also what might be some pros and cons of running this setup? It is in a street car so it would be ideal if feed back was baised off users who had it on the street not the track. How would this setup on the street compare to the same thing but with a 20g?

The short answer is the 2.3 moves the power band to the left (power comes on sooner, but also dies off sooner). It'll feel like your 2 litre now, except it'll come into boost earlier but also die off up top earlier in the RPM range.

Do you do anything with your car other then daily drive it? AutoX, drag race?

a 20g would be a little more power and or a little laggier depending on the turbine wheel / housings used.

Although I've never personally driven a 2.3l, many people claim that a 16g will choke the larger displacement engine. There are a lot of threads on this throughout the years.

The 16g on a 2.3 will feel pretty much like a t25 as far as spool and dropping off up top but you will have more power. It all depends on what your end goal is but I wouldn't do anything less than a 20g. 20g will probably still fall off at top but it won't as bad as a 16g.

I won't be using it as a daily. Will mostly be a weekend warrior. I will sometimes bring it to the dragstrip but not near as often as it being on the streets. Also I will be using it in mountains alot for canyon carving

If you have a 2.3 I'd suggest a v2 68hta/FP green With the added displacement you'd see full boost in the mid to high 3k range depending on where your cams are degree'd and what boost it is you're aiming for of course. My cousin has a 68hta on his WRX with a 2.5 swap and the thing starts spooling instantly any time you give it gas, it's like a 14b on a 2.0.

This statement helps alot. Your honestly going to want to look into a small cam setup. GSC s1's or the like. An EVO 3 intake manifold will also help. If your on pump gas 750 to 950cc injectors will be plenty, if alcohol (e85) then something in the 1200cc range will be needed. Don't skimp on the clutch or suspension setups as those will show there short comings really quickly in a car that goes around corners!

My last setup consisted of a 2.3 stroker, FP2 cams & an EvoIII16g with the turbine clipped 15* at 22psi.

Always had 0 psi whenever I tapped the pedal and full boost by 3k and power would peak at 5500 and level from there.

An intake manifold would have more the powerband further, at least 7k. I wouldnt spin it higher than that, though since its a stroker..

I've presently ended this project. Changed to a
2.0 as not enough locals could help me with it. The person who was passed away. A good deal on a built 2.0 came up so I took on that as my base motor. Will be cheaper in the long run for better power.
