i just bought this car two months ago.

a month ago after goin on a 3 hour journey topping it out at 110mph on flat i ended up very unhappy when i headed up a long but non steep incline. as i begame to go up the car slowed down alot all the way down to 80mph. i know i shouldn't be speeding but it was 2in the morning on route 17 if you know where that is. the reason why i want to get around this much hp (or even better whp) is because people in my town rag on me because i have a honda. so i want them to know that honda's can run too. i'm goin for naturally aspirated sleeper type. ok but my questions are.....

how should i start the owrk on the engine?

and i know i'm goin to have to do a few things to the transmission. what will that be?

I think so, dude it is easy to make 130 with a d16z6 engine but after than you get into internals and all that stuff. Weight reduction is the best thing you can do to a honda to make it go faster. WHP doesnt directly equal speed.

aim for an ET not HP, your better off with a ET goal...it all depends, shoot for low 14's mand u be respectable all motor...Big Tuna runs 13.6's in the quarter in a CRX on slicks...but dont aim that low cause that took some doing to get there, first thing is to raise ur compression, more agressive cam, and a good 2.25 or 2.5 exhaust...ITB's if u want to take this seriously, and the typical bolt ons, throttle body, headers, intake Hondata spacer for the IM...

Honda pact i dont think he realizes the cost of that. Look around the site first. ITB's are great but will cost a fortune if you cant tune/have no idea wtf your doing. Good luck.

that would be the most logical thing for that kind of power but this is in the N/A section

No offense, but if it won't go past 110 there are a few dead horses under that hood. It should quite easily break 125. Does it pull hard past 5500rpm or does it fall on its face at high rpm ? If so, Vtec might not be actuating.

Anyway, you can make 140-150whp from that engine N/A without spending your life savings. That equals approx. 160-180hp at the crank. It'll still run well into the four digits $$$ wise.

My Concerto does 130+ on the speedometer with ease and it's 150-200lbs heavier. And that's with a sohc non-vtec zc. It does have a gearbox that's a tad shorter, I'm at the redline at that kinda speed.

Hondata gasket isn't dyno proven. It could be easier cool intake in a shorter lap of time , but remember that, studs, coolant to TB, coolant to the heater passing trough the intake keep the intake warm. The only thing I see to buy this gasket is about it's reusable.

ok one cost doesn't matter. i made more then enough money to go out and buy a corvette if i wanted to. but i can't afford insurance on it since i'm only 19. i don't want to swap motors or anything like that.

I'm gonna go w/ everyone else and say you need to set a REASONABLE ET goal... or if you really want some power; get boosted!

i'm guessing you have a differnet 5th gear as well; z6 tranny isn't gonna make it to 130....

corvette insurance is cheap... and if you cant afford insurance in monthly payments on somethin like that... then you definately cant afford to build a quick NA honda

i know it's not cheap. i have more then enough to buy one but i can't afford the insurance if i get one thats why i'm not goin to. but i changed my mind on the NA engine it's just much easier to turbo it.
