Hey everyone! Its been a while since I've been on here but wouldn't go anywhere else with my Honda questions. If any of you remember I was doing a mini-me swap in my 98 4 door about a year ago and had numerous questions being my first swap and all. Anyway, the D15b V-tec is running great and havn't had any problems with it at all.

I'm looking to do some upgrades with out tearing into the block and head for now. I have headers and exhaust, short ram intake. You know the basic bolt ons. Sooo, what I'm lookin to do is keep it N/A for now and wondering where can I get more power. I'm thinking new intake manifold but from what im seeing everyones saying the Y8 intake mani is good and no reason to change it. How big of a throttle body should i go with being stock internals? 68mm? 70mm?? Can i change to bigger injectors and if so what can i get them out of or what size? Whats everyones opinions on TB spacers? Do they really do anything for somethin like this? I know i prob need to port match a bigger TB if i get one but just wondering how big and what kinda stock upgrades i can do. Since i got the exhaust i figure some intake and fuel upgrades would be where to go. How about a obd2 Vtec controller for the P2P?

I plan on building a head later down the road but for now im just looking for minor stuff to play around with. Any help would be greatly appreciated! im sure i have more questions but will ask when i figure them out lol

for now just save up your money. If you want go buy hondatas300 and a p28 ecu or work on your suspension and body.

The body just got straight actually and just ordered headlights and yellow fogs to finish it. now im tryin to pull out a lil more power in the d series. eventually gonna b16 it but i wanna be different with this d series as far as the injector upgrade and stuff like that. i know i can save up my money but thats not what im asking im askin what will work and your opinions on the diff parts

LOL...thats just wrong -.-

You realize a bigger TB, a bigger fuel injector, etc....all told your adding like 2-3 hp right?

I dont want to burst any bubbles but if you want to see any noticeable power gains, it is easy...swap or turbo. The D series can make power (if you have alot of money to spend) or want to get into turbos.

Take it from the guys that have gone through the headers/exhaust/bolt ons/ waste of money. Save your money for the swap. I've read people saying their "throttle response" was greatly increased by Y8 mani swaps, and then I look at dyno charts and stuff and they went from 108 at the wheels to 110.

Get suspension....spend your money there. Driving a slow car fast beats the hell out of driving a fast car slowly

You cannot and will not get more power out of the d-series without ripping apart the block or adding a turbocharger.

Leave the car alone. I did for 5 years and now I'm having the build of my life. A lot of members of this website are excited about it along with me.

Baisc turbo charger kits (quality ones) can be had for $2,000:

A turbo is literally the most cost effective way to go fast.

Modifying a d-series is a total waste of time unless you're bolting on a turbo charger. It's been proven over and over that bolt ons on a d-series mostly just make it louder and shift power from the bottom end to the top end.

Get your suspension done, and start saving money and researching what you want to do with your car. It's what I did, and it's what most veterans will tell you to do. You'll thank me a year from now.

The best thing is to keep it freshly tuned up with OEM ignition parts. Keep clean fluids and filters in it. Otherwise it's all just a waste of money. Although I do think an Intake system is good for ANY car because it increases MPG, throttle response due to the less restrictive path. They are cheap and easy to do. Nothing will gain you a lot of power on these motors other than Boost as stated here 1,343,453 times. Ohh and adjust your throttle cable
