Skunk2 IM or OEM (jdm) on h23a

[DragonEye]

i cant chose if i stay with my h23a jdm intake or i put on my skunk2 intake/TB

every body down here say i gonna get a 5whp gain over a 2wtq lost.... i understand is more complex but in simple is somewhere like this....

i got the IM/TB almost for free (100$) so.... i need fact,faq, tick and advice on what to do !

Thx !

(oh, and i did my work i search the forum for clue and aint find nothing)

** sorry for my poor english

From my knowledge the JDM (Euro) intake out-flows the Skunk2, hands down. But fitment does take some work.

Depends if your h23a is a p13 or pde stamped head.

I dont talk about de euro r intake manifold but a h22 one (i put a h22 IM for the 3 to 2 wire conversion.

And staped p13 hf-2

Simply put, the skunk2 manifold is supposed to match their camshaft. On a stock engine, you won't see big gains, even tuned. Bolted right on, you may lose power l, the big difference comes with tuning.

If you own it, put it on, and send your oem h22 plenum and lower to be ported by Rosko, then change it back out and sell the skunk2.

this engine have typeS cams, it look like the same as skunk2 stage 1 but i cant be 100% sure,

thx everybody for the advice,

someone have more idea ?

[DragonEye]

here the pictures

The type s cams are similar to the skunk 2 type 1s. As far as the I'm, you would gain more with a gutted stock plenum and runners vs the skunk2. Skunk is designed to go hand and hand as far As gains in power.

But I have seen dyno runs with skunk and a gutted stock manifolds, I will say gains differ on builds but the gutted plenum beats skunk by 2-5hp and.

Gutted manifold?

oh ! well cool, but i aint have flowbench and dyno to work with to tune this up....

I had my car on the dyno yesterday and, without changing my tuning, I picked up 4hp at the wheels. Tuning added another 3hp and I gained 2ft/lbs. Those are peak numbers, but the graph showed gains all across the power band, some mid-range gains being as much as 10hp. Those are all gains over having an IAB delete and a 70mm throttle body on a matched plenum. As long as you use the Skunk2 throttle body and the manifold is ported to match the throttle body, you will see gains throughout.

over the stock H23a IM ? or a sk2 one ?

That was over a H22A manifold with an IAB delete and a port-matched 70mm throttle body.
