hehehe. Just trying to gather some ideas and get suggestions on my y8 head. Tried and true suggestions. I ask, merely because I dont have much knowledge in honda heads. Im not asking anyone to give me prices and a parts list, just suggestions, and a kick into the proper direction towards my present goals. NO BS JUST INSIGHT.

Im looking into building the y8 head i picked up for my 96 hatch. Now, no bs just onto what my intentions are:

Id like to rev to 8200 SAFELY, would like 8500, but im not to pushy, especially when intentions are daily driven.....80 miles a day to and fro work.

The head will see boost for sure, hence the higher rev limit. Ive been looking at different companies for the valvetrain, looking moreso into crower as they are a pretty solid company. I want it to be safe, reliable, and powerful.

Ive also been looking at intake mani's and would like to stick with the y8 mani. I read briefly, and couldnt find the info in my searching about cutting and welding the mani, as well as having some work done to it as well.....If someone could really shine some light on this subject, that would be great.

The bottom end is going to be reworked as well, with forged units from a company i have not decided on yet, but that will be worked over later.

Basically, My overall goals with the built y7/y8 are pretty obtainable, being 275 for daily cruising, and up to, but not necessarily 400hp for the drag strip. So....If some of you knowledgeable guys could shed some light on this topic, and give me some pointers and insight, to get me in the correct direction, please do

 

 

you better build the rest of that motor to be asking for that much power. D16 with stock internals won't last a day witht hat much power.

Reread my first post...... Is it so damn hard to comprehend what is being read? I thought that went hand in hand.........

 

I dont think you want a 400 hp car for a daily driver, you save your 400 hp car for the weekends and buy a inexpensive daily driver for work. its very difficult to put 400 hp into a d16 anyways. you will have to build your whole motor up to handle the amount of psi's needed to run 400hp. To make a long story short its gonna cost you a lot of money to get a SOHC runnng with 400hp, also to get 400 hp you are gonna have to run a lot of boost. There is nothing wrong with running a lot of boost but the down side is turbo cars arent meant to be daily drivers. Turbos run with a lot of problems. with your intentions you will find yourself putting more money into parts and putting it in and out of the shop. i know a few people with turbo daily drivers, and there car is in the garage more than it is on the road. all the cars have had parts replaced plenty of times. my best advice for you is that if you want a 400 hp daily driver you will have to get a way bigger motor than a 1.6L SOHC. Boost usually runs better with bigger motors, and a bigger motor can help you achieve 400whp way faster than a smaller motor anyways.

 

Why does it matter what you'd like to rev to? Dynojet the car, and when it stops making power at 7900, that's when you shift. If you want a totally top end motor, you should've bought a Type R motor.

 

correct the d series y8 engine wont make power very well over 7800 rpms..
but they do make power.. ive been watching a thread of some one making 300 whp stock block single cam and previously ran it at 250 whp for several months..
they do make power and will last if built and tunes properly ..

yessir im following that thread pretty closely myself. To add to that, I have a buddy in my home state who has a 98 civic ex. He added turbo to it at around 95K miles, 9 lbs of boost. Roughly a year later and some 25K + miles he upgraded from the t25 to a t3 and upped the boost, and went with better fuel control. he runs 12 psi on the street and has went up to as much as 17 lbs on the track. Id say somewhere in the neighborhood of 230-250 hp, and is very close to the 150K mile mark. He went to the track pretty frequently as well, id say at least 40 runs in a couple months time.

If you guys would please read my initial post a little closer, you would see my goals are 250-275 for the daily driving thing.........which is completely feasible. The car has yet to see a 1/4 mile strip since ive owned it, and the previous owner used it as a commuter for 3 years. And being there arent any 1/4 tracks within 2 hours of me, it might see one or 2 track days.

Anywhoo, thats not what my topic is about, im interested in a complete valvetrain upgrade. none of which has been talked about yet. Everything posted sofar has been pretty irrelevant to the topic at hand.
And to add to why id like to rev higher.....that way i have more time in boost, the snail i intend on running probably wont reach full spool until 3800-4000 rpm.
