Custom ported and CNC throttle bodies, upper and lower manifolds by Synergy Composite

G37Some

i'm not here to argue with you syno, some single turbo builds are putting out 200+whp gains for 9k installed, brand new. ~45$/whp - even less if you buy a used kit.... stillen intakes, fast intentions hfc/cbe, uprev tune = up to 50whp gains and cost ~$2900 (+install if needed). ~58$/whp. The fact that you are doing more than these mods for less $$$ is great, dont get me wrong. my car is full na too, i don't have the 9k to shell out - but just saying.

knowledge is power. keep testing, providing knowledge and paving the way for others to reference! I legit wanted to do the porting of upper intake manifold and TB's if this had good results. Side by side dyno run with your friend is an awesome idea and will be an awesome reference if you list his exact mods in comparison to yours.

I'm not arguing either. I just know its the dyno. Megan got 68hp NA. That puts me at $32 . So I win haha. I don't have it either and never would! That's just insane. I'd build my own like I have before. Way I see turbo kits is a few grand for turbos and parts then you end up paying several thousand for the pipe. Just a rip.

I'll keep on it. It can't not show results. Increase air, increase power. Simple as that.

well that 68whp as cost me a lot !
if you take in consideration the amount of time involved in what work and what didn't and redo the test later on to confirm .. it was an expensive one.

I had an edge in the beginning until I blew the engine now that 60+whp is common using normal pump gas and using the right bolt-on available parts.

with all the side cost involve in each mod, the price can get high
so far my estimate is like this
custom CAI 1500$
Oversized TB 625 $
HR intake manifold ( 150$ ) (not good for peak HP )
crank pulley 250$
custom PPE lth 1500$
x-pipe and muffler 1500$
Uprev software 700$

total 6225 for 68whp in the end which mean 1 hp / 92.54$
I could have used cheaper part to make the setup drop 1000$ from the total can bring the Hp/$ ratio down to 76.84$/hp

it could have been cheaper if I was in the US but the shipping cost is a lot thru the border.

that 68whp isn't the minimum that platform can gain and as I said , I believe seeing another 20whp is quite possible still using pump gas 91/93.
I didn't had the VHR intake manifold ported like Z1 started to do after I did showed how badly the intake runner were matching up.

Not completely true.. If you add up everything other than the piping, manifolds, oil lines, vbands, hoses, etc. for the Boosted Performance kit, you are still over $5k. Sasha sells the full kit, ready to run without so much as going to the auto parts store for thread sealant for $7,150 and its capable of a safe 550 HP. Throw in $750 for a tune and you are still less than $30/HP
