is this it for N/A?

Make them look like mine.

Plus 1 valves start to get into the DI quench area and negatively effect the combustion process. I suggest to port heads and leave valves stock

Did you gain anything by doing that?

My build is a total custom F/I build so I have no idea or way to measure hp gains because of lack of reference. From a flow wise point of view yes about 19% tho the real advantage was matching the port flow percentage of all 4 cylinders. All 4 cylinders are not 100% equal but they are a lot closer now than stock configuration.

I suggest calling Delicious Tuning for a STG 2 tune with a PPE header that will solve 99% of your problems.....


No disrespect intended

i don't know exactly what he has under the hood but he told me he had about 220-230whp and on the highway his third and 4th are definitely stronger than mine.
on 94oct i ran a 14.3 quarter mile with stock tires... not to shabby if you ask me.
its cool your advertising delicious tuning and no disrespect but come on i have stage 2 and headers i don't think im making 160whp and with delicious id be making 200whp. give or take maybe 5-8whp between a different setup...
so its definitely not that, my point is that rsx k20 has more n/a potential than us, and i wish we had just a bit more options.
that is all.

[Vroomin86]

do realize that an OFT tune is not the same as an actual tune. But yes, I will agree with you that the k20 platform has much more support.


Then again its in about a handful different cars, a lot more than ours.

yes i know an off the shelf tune will not be as precise and squeeze every pony out.... but it wont add 20whp either... so who cares.
and yeah true, i agree with you, it just seems like the n/a scene just kinda died out... but thats just my opinion thats why i came here to ask , there is alot of knowledgeable people here and im curious why it kinda hit a celing at 200whp.!

[FastWhite]

And how old is K20? How much more development has it had? How old is the FA20? How much development has it had?
It will get what it gets.
I like my BRZ, growing up with my favorite car, an X1/9. I had it rebuilt, balanced, cams, carburetor, header exhaust, intake manifold. It put out an amazing ,100 hp!!!!!! From a 1.4 liter.
Everything is relative, different times, different standards.

lets do some math equation is time vs weight to move a known distance equals hp


Your HP is 192.63 computed from your vehicle weight of 2850 pounds and ET of 14.3 seconds.


Your HP is 185.87 computed from your vehicle weight of 2750 pounds and ET of 14.3 seconds.


Your HP is 179.11 computed from your vehicle weight of 2650 pounds and ET of 14.3 seconds.



I ran 13.47 at 2750 in 90% humidity


Your HP is 222.39 computed from your vehicle weight of 2750 pounds and ET of 13.47 seconds


Now I did have slicks and so that's a advantage but as far as a base hp no corrections the math is what it is


So with stock tires to run a 14.3 is pretty awesome I would say that's a solid 13.9 run with tires so the only thing left is tune and exhaust
exactly how bad did he beat you 1 car 10 cars




I understand other factors apply like trans gear ratios if he has a 5 speed to your 6 speed

that maths makes so many assumptions its really not worth much
same launch
same reaction time
no loss of traction
gear change times equal
drag co-efficient of vehicles is same
it working out average HP applied to the mass over time
ect


You forgot to mention you were on E85,
head work done ??
final drive ratio ?
lightweight components ? wheels flywheel pulleys driveshafts
full interior ?
stock clutch ?

That's what a stage 2 tune is is E85 at delicious tuning I apologize for the confusion I shouldn't assume everyones stg2 is the same
Motor is bone stock no changes except oil and filter and number 1 coil pack on warranty
it has a act clutch and street flywheel not the super light one
stock driveshaft
full interior minus passenger seat and spare with jack and tools also removed to go 13.47both seats in at 13.56
4.56 final drive to get to 13.47 stock gears running 13.80s
no pulleys all stock engine
reaction time has nothing to do with ET'S


but this I do know
you can drive because no one will run 14.3 on stock wheels granny shifting and not knowing how to launch your car so I would assume gear shifting and all the other things you listed are about equal so for me the math stands
so in closing I was just want to say at one time I held the worlds fastest FRS N/A title I was the first to break 100mph in the qtr and I have ran a 106mph trap before N/A which no one else has done. I'm just trying to help not offend anyone I hope you figure out whats wrong and beat the rsx

id probably say 1-2 car lenghts, but it would be even more if we kept going ( i dont like highspeed) lol.
Nice time on your car by the way! mid 13's would be quite fun.
In this argument though, comparing normal gas like 91-94 with E85 is not really comparable. because then the rsx could do the same.(which its not).
I know i need better tires and it would help alot but my whole point was that he has 220-230whp with headers/intake/manifold(im guessing now from researching), and all i ask is will we be able to see such numbers IF companys were to make manifolds/cams ect.. or did we just hit the ceiling already?

also , , final gear, radials/slicks w/e yeah itll make your 1/4 mile faster but im more interested in engine potential.

fullblown and velox have done intake manifolds but judging from lack of info, dyno results ect I suspect they didn't gain much NA. else i am sure they would be advertising the gains. maybe they work well FI ??

im a bit disapointed that an old rsx type s with just headers is faster than our cars and id love to see at least a 220-240 range WHP N/A ....

But can your RSX drift?
