Hello, I am new to this forum and figured I have to start asking questions somewhere. Also I want to apologize that I could not post any pics at this time as I had trouble inserting images from my computer. Any advice on how to post saved pics would help too, LoL. Okay here is what I got

-'99 Civic EX 5 speed 4dr with the stock D16 motor and tranny (144K odo)

Mods
-JRSC professionally installed w/stock pulley dyno tuned @146.29WHP and boosting 6.94psi at the peak of the curve (96mph)
-lower end (cheap) header into exhaust system off an Acura RSX (quiet)
-Cold air intake
-Eibach struts

What I need help/consulting with is I want to get this car reliably up to around the 180-200HP area and would prefer using the supercharged setup I already have. I'm not wanting to spend thousands to get there either if thats what it would take. I know they make a different pulley I could swap out with but I was told it wouldn't do a whole lot. Is this true? What suggestions does anyone have to increase my HP using/improving my existing setup? Head work? Cam? An expensive header? I'm not looking to break any speed records, I just would like it a little bit faster than it is now.

Anyways the car is sharp looking and has been really well taken care of its whole life and looks like its a lot newer than it is. I do not drive it daily and it spends a lot a of time chilling in the garage. I want this sucker to be a runner but yet reliable in case I would have use it for work or something.

All suggestions will be read, except NOS suggestions, thanks ahead of time. BTW I have pics of car and motor.

 

Need to UP the boost, AKA a different pulley. I would say 9-10psi will get you in the area of where you want to be with a cam... and some headwork wouldnt hurt either.
I suggest the zex 59500 on singles. Seems to perform well with FI setups as well.
Going cheap on a header can also be a power killer, adding air at higher speeds/pressure requires it to exit at higher speeds with better flow and better efficiency. Might be an area to consider.

40whp is alot. I know for the typical turbo setup, typical as in what everyone is dailying from a "kit" with a 54 or 57 trim, with a good tuner and setup you can expect to gain 10-12whp per psi of boost. With that said I have no clue with a SC setup.

What kinda budget are you on?

 

higher compression, cam, better header, more boost by switching pulleys. Also look into modifying the intake manifold so that you can use a m62 blower.

There is a guy in the JRSC thread that has a custom manifold for his sohc and i believe he still has a jig for it. He made it like the LHT manifolds with cores in it for cooling after the blower.

 

I have a similar setup to yours, right down to the car. I would recommend finding a better camshaft, then upping the boost.

 

Post up ur dyno sheet. Your exhaust system seems very restrictive. Fix that 1st before upping the boost.
What was the car tuned on?
