No money for a turbo...

so i was wondering what are some of my options for increasing power in my mini-me swapped d16y7 with the y8 vtec head.

currently has: d16y8 swap, p28 chip, intake, headers and exhaust (both egay brand i think), H&R sport springs, Koni Yellows, Skunk2 adjustable upper control arms (front), Skunk2 adjustable LCA.

no cat on the exhaust btw and it's all a 2.5" and exits from a "stock" muffler.

Not looking for any more suspension work, i've done enough, i just want little things now that i can easy install like maybe a fuel rail and some injectors? but without a turbo injectors probably won't do much am i right?

i'm a noob when it comes to engine mods so help me out please.

also, my car is nowhere near riced so i don't want to go towards that direction.

 

The injectors only help once other things have added HP. Try some headwork, if your handy with a dremel, you could port-match the head and Intake mani, get better airflow and characteristics there. Maybe a mild cam, if it's a DOHC, some cam-timing gears would be alright (need dyno to tune them really good though, i guess). Right now just concentrate on improving the flow of gases through the head, and learn as you go.

 

Turbo is usually the cheap alternative because you can practically piece a kit together but if you're really on a budget you should start researching nitrous. For what you have I wouldn't suggest anything more than a 25shot. There are no simple shortcuts to gaining power though and you need to know what you're doing in order to make progress, oppose to just throwing parts at the car. Also im pretty sure injectors and a fuel rail are not going to benefit you at all.

 

main problem with nitrous is that it only gives you power when your spraying, and you can't spray on the streets (well, you can, just pray you don't get caught)I say he can go 40 shot if everything is in good condition, how many liters is that engine anyway (and CR for that matter)?

 

With only around a 90-120hp I definately wouldn't recomend a 40. I've seen a GSR break its cams in 4 pieces with a 50shot because things were'nt done right. A D16 is a 1.6L with 9.6:1 compression and has a little under 1600cc. How can you recomend a 40shot and not even know how many liters the engine has. Everything being in good condition is only one of the many factors. More importantly the kit has to be installed correctly with a reasonable shot size, bottle temp, PSI, etc. The best advice I can give is get with a professional that knows what hes talking about and/or do the research yourself. You can start in the HT Forced Iduction thread or here: http://www.nitroustech.com/forums/index.php

 

I can recommend a shot size because I thought it was a 1.6, just wanted to make sure(but now that I think about it, 40 is a lot for that, and 20 hp isn't worth the money). If the bottle psi is too high, the 20 shot could turn into a who knows what and break it just as good, so let's assume, theoretically, the kit is in fine working condition. He might not be able to get n2o in his area, I can't. With zero sarcasm, how did the cam break into 4 pieces(or just, how did it break, I'm really stumped there)? To be completely honest, your basic physical install of a kit is a piece of cake, but yes, research is required to get a few basic rules down before you start. 2 days on nitrous forum.com and he can install a basic dry or wet kit (I'd go dry for the first time). Anyways, let's shut up at each other and help him.

 

Upgrade your ignition, fill up with premium and advance the timing. Injectors won't help you and will actually hurt performance on your current ECU. Of course, if your current injectors aren't performing up to par then replacing them with new ones of the same size could help somewhat. For a fuel upgrade you should probably start with a stronger fuel pump. You can get rid of the PS if you have it. Ditch any subs and look for other ways to lose weight.

 

the solution is simple. a shorter aftermarket final drive. biggest bang for the buck youll get. those D series trans are worse than the "LS".

youll swear you added 30 hp.

 

nos is out of the question, but you guys have given me a lot to think about.

i think i'm gonna start piecing together a turbo.

question: what is a good psi to boost my stock motor at? without building it up.
also, my head was rebuilt it if matters and only has 2.5k miles on it.

another question: what are ALL the components i will need to boost it? (all turbo parts, bigger exhaust or no?, etc.)

thanks.

 

Yes agreed, I dont want to stray off topic. But I did take pics if you're interested. And for the side note I didn't mean to be offensive or come off as a as*hole lol.

 

funny how probably one of the most reliable and realistic mods doesn't even seem to be on the OP's radar.

As a "noob to engine mods" the last thing you want to do is fab a turbo yourself, then again messing with your trans probably isn't a good idea either...i dunno.....if you overlooked the above statement OP.....revisit it. Conan is right and you don't risk the reliability of the motor by doing this mod. My .02 cents.

 

I would like to see the pics, MK; never heard of that happening, do you know any specifics on it?

Piecing together a turbo is something that takes a ton of preperation of a parts list, mostly gaskets and fittings is what'll trip you up. Can't say a good safe psi for your engine, but just to get the ball rolling for that discussion, how's 6 psi sound on something like a t25 (I think that's what it called).

 

i just don't wanna get an expensive new kit. i would even settle for a used kit for the right price.

and 8psi is the max i would boost it, but it's a very solid motor and handles a lot of beating lol.

 

 

Try and remember youre still in all motor. Look in turbo section, I'm sure if you search you'll find answers to all your questions.

 

i dont know what any of that means..

 

then dont take offense to this, but you dont need to be messing with your car at all. leave it alone. stick to oil changes and putting gas in it.

what did you come in here and expect? someone to say something like "twist this bolt, plug this hose, cut this wire and youll gain 50 horsepower, oh and here are instructions with pictures, better yet, ill come to your house and do it for you and you can fukc my sister when im finished"

come on man. these are cars. you dont just post on honda-tech, snap your fingers and get a 20hp gain out of a D series.

there are too many threads like this where people come in and ask for free/easy horsepower. that is desperation.

 

then get the fu<k out of the thread if ur not going to be helpful?

nobody is forcing u to help me, i know PLENTY about cars. Enough to fix almost anything that goes wrong NOT involving the actual motor itself (inside components) only because i haven't had to ever do it yet.

i have no experience with it so why would i mess with it? get off your high horse and stop hoping to god somebody quotes you and agrees.

if you don't/can't help me, simply click the back button and move on with your life...

 

youve got bolt ons, you cant make anymore power unless you really get into stuff with the motor so dont bitch when someone tells you that, its the truth. and get rid of that p28 chip, the timing maps are all wrong for your motor, you need it to be a y8 map. Gear changing will be your friend. a 4.7 or 4.9 FD will run you around 500 plus install and it will be the best mod by a LONG shot you have done to the car. and im also confused here, you say it has a y8 swap but than say you have a y7/y8 mini-me, what is it? If you dont have a z6/y8 tranny, get that before you go any further. That alone can drop a sec. off your 1/4 mile times, than change the gearing in that and you get the picture.

 

I agree with conan about the new guys coming in and asking questions about s#it that the search engine could answer.on the other hand I don't no why the oldheads have to post in every singly thread that a noob makes saying the same s#it over and over again. like he says if your not going to be helpfull then click the back button.its called honda tech not honda I no everything and you don't no s#it go search.just my 2 cents no offence to anybody

 

No I dont have a specifics but I do have pics taken minutes before it happened. I have more but I dont feel like resizing them.



On subject:
I agree with going with a final drive is the way to go if not turbo or nitrous.
Nitrous only gives you power when you spray, but turbo only gives full potential power at WOT... Same principals.
I would'nt recomend an Ebay "egay" brand kit unless research on the manufacturer and kit are availabe, but if you're despreat for power by all means.
Final drive is win/win though.

 

8psi with what turbo? 13.7 psi would only increase rod load by 20%, surely the D16Y8 can handle that. If you tune, wich you should, and eliminate the possibility for detonation the engine will be just fine.

 

ok, first off we need to know your exact set up.

d16y8 or y7/y8 mini me and what transmission?

im not up with all the gearing, so i'll let the other guys handle that one. but i would add a decent clutch (if staying all motor, no more than a stage 2) and a lightened flywheel (prob. like a 12lb). then after that i'd get a nice mild cam paired with a skunk2 intake manifold and then get an actual tune on your ecu for your exact setup.

those lil things combined with the right tranny setup will make some really nice, noticeable differences.

if you still want more after that, then i'd look into boost. as for guys telling you that you shouldn't be piecing your kit together yourself, bullshit. my first turbo setup i did i knew NOTHING from the start. but i researched a lot and taught myself what i needed to know to get it all together. i'd highly recommend checking out homadeturbo.com for learning about boost. thats where i learned from and by the time i was ready to put it on my car, i knew all i needed to know including what lil random parts i was gonna need.

sorry for the long *** post but hope that helps you out

 

stock d16y7 tranny it comes with idk what it's called.

 

you need to ditch that trans ASAP than adding just a y8 will make a world of difference like i said above
