boost is a bitch. I love having black smoke billow out of my exhaust and breather filter

seeing how much money u have in ur sig the best option would be to swap in a k20a2 from the rsx-s cuz an ep3 would run u the same and boosting a the dmotor would still not get u as much power as a k20a2 would if u swap that in...just my 2 cents...do the k20a2 swap...if that too expensive than boost ur coupe

Uhm. . . . YNOK20 . . . . what do you plan to DO with your car?

Drag race?
Autocross?
Track racing?
Street racing? (Please don't)
Look "mad tyte yo!"?

Give us some information we can use, then we can actually help you in your quest to determine what you should do with your money.

I have problems from time to time. But I also run 12-14psi whne my mind goes numb. I dyno'd at 10psi and made 231whp. So figure 10whp for each psi and I was making at least 250whp at 12psi. Add back the 15-20% drive loss and I made a shiet load of power at the crank.

Yeah I blow headgaskets like others blow out candles. But I didnt put on a turbo to be average. I can smoke most allmotor cars. I have beat a B18 hatch, a GSR, Mustang GT, Eclipse GS-T, etc....
I got beat by a modded Camero SS. But damn he has a 5.7l engine. That is 4.0 bigger than mine.

You can boost at 7psi all day with no problems. Just buy a used SF kit bolt it on and call it a day. Just dont crank it up to 12psi and expect to be safe about it.

250 @ 12psi?

Jesus. . . I'm only laying down 256 @ my stock 15-16psi. And I've got .8 liters of displacement on you. Just doesn't sound right.

Here is my dyno when I tuned at 10psi. I did not push it on the dyno. But at the track I cranked it up a couple more psi. So Do the math and I know I came close to the 250whp mark.

I dynod stock at around 98whp. 10psi of boost made about 130whp over stock. add two more psi and you got a total above 250.

Here is my dyno:

Damn. . . I see it, I believe it. . . just wish I could understand HOW.

Sweet dyno pulls, Guns.

^ these cars actually pull hard when you boost them. Torque steer like a biaaaatch

Torque steer and wheel hop at the same time. Here is a pic of me on the dyno. Enjoy.

turbo

I'll answer this for me personally. I just want a car that hauls *** for a daily driver. So i think a turbo with 5-7psi would do me fine. Does anyone know how turbos are in the winter? Obviously i live in a colder climate being from edmonton.

Here is the K20A3 with a Jackson Supercharger:

hmmm... isnt a EX and SI the same thing???? ... the only diffs i know between them is there Emblem lol...so whats the diffs between them? well they both got vtecs right?... heh sorry i am a newb...

ex US version = CDN Si
Si Us version = CDN SI-R

The EX is a D17 vtec

The Si is a K20A3 i-vtec

For looks, EM2, for performance EP3.

For what I'm into, I'd much rather have the new Civic Si than my 02 Civic EX. Im boosted, have very little problems, but the support for the K series is overwhelming.

If you're budgeted though, then keep you car and boost it, it's tons of fun lol

^ yeah it must be a great enigine to work with

The title of the thread is Turbo Coupe or Civic Si.

Based on that, I would say why would you settle for 125whp from the Si?
Yeah the Si has a K20 DOHC. But stock non-turbo is weak. You could spend like $4,000 for a Greddy Turbo Kit or a Supercharger and make 200-300whp.

If you already have a D17 find a used turbo kit for arround $2,500, bolt it on and you can double the base hp of your car with no problems. 200whp can be made it about 7-8psi with the right tuning. 250whp is possible on stock internals and I will prove it soon. As soon as I get my built block I will see what the stock engine can hold.

i wouldnt settle for 125whp i will boost the si

ok how about this EM2 w/turbo or EP3 w/turbo cuz thats what im looking at

boost the d17, or juice it?

awwwww **** a got the civic si but i got white instead of black its so tight i wish i got this in the first place i will post pics later

Jackson racing Street supercharge cost less than $3000.
6psi with bolt ons. 205whp.
Race kit is coming out soon for civic si's.

Revhard turbo kit, which include hondata upgrade cost less than $3500.

K20a3 with bolt ons.
160-165whp.

The jacksonracing website says diff. I dont think you are making 165whp, when the supercharged version is only makeing 175whp w/ intake, exhaust, etc..

Dyno numbers can varie.

Mods
AEM CAI, DCRH, Fujitsubo RM-01A exhaust, Hondata IMG, and Nology hotwires. JRSC Street version at 6psi untuned



Mods
AEM CAI, DCRH, Fujitsubo RM-01A exhaust, Hondata IMG, and Nology hotwires, reflash

With a white body i'd get bronze wheels

yeah thats what im thinkin im looking at Volks Racing LE28N 18" but they cost a grip i found them for $2300 with out tires so i dont know. i found the greddy turbo kit for that much with out intercooler.

here are some pics of my new car and the rims i want

superchargers suck those are some crapy gains for that amount of money for that it should cost less then 2Gs

those are the wheels I had in mind. they look sweet
