i have a stock 98 si engine (d16y8) i just want some opinions.. should i modify the stock engine with interals.. h/e/i/ etc.. or should i do a b18c1 swap and modfiy the engine slighty with just h/e/i/.. my goal is to get around 175-200 whp maybe a bit less or a bit more .. also im looking to only spend around 5-7g on performance upgrades for my engine.. also my stock d16 has 123K orginal km on it.. thanks for ur opinions

stock94block

well im in an almost similar dilemma...what to do what to do?! i have a D15 ok so ill tell you what im thinking. Youll need to turbo the D to get that kind of hp, for 5-7 G's you could turbo your motor..dont care what anyone says, turbo kit, plus intercooler, plus tuning..around $5000 no doubt..check turbod16 for more info on that...and with tuning you dont need to build up your internals and still run like 10psi..maybe more..

what i would do with your LARGE budget..buy the B18C, do your bolt-ons and you will easily get 175 hp AND will have less to worry about because you just bought honda reliability!

im not bashing d-turbos here, i love em..but if i had your budget thats what i would do...less hassle, and B18's are proven...IMO!

i dont have 5-7gs to spend right now i was talking about over a time period.. i want to build up my engine slowing. and if i get a gsr it'll be after the summer cause that is when i will have the money for it then ill be broke and wont be able to spend that much on modifying the motor afterwards.. its quite a dilemna urgg

scarlemthug

well u can spend 3-4G's on a turbo kit for ur D-series and get around 150-200whp id guess. Or your other option is grab a GSR complete swap for like 3-3.5K and install it in ur car, then over time piece together a simple turbo kit and u can easily hit 300whp on the stock engine with around8-10 psi.

markpa

U should be able to piece together your own kit for about 1500, it varies on what fuel mang. u go with ....and then u need to tune it.

homemadeturbo.com is a good site.

chris_si98

if i get a gsr swap i will NOT turbo it.. i wont have the $$.. i will most likely just do h/e/i and MAYBE some type of internal work if i strike oil in the future.. so what should i do for the summer.. d16 turboooooed? or gsr swap with very little mods?.. also i was thinking since my d16 is a SOHC vtec .. i was thinking maybe get a different head.. maybe b16a2? u guys think that would work out? give me some feed back.. my engine is BONE STOCK right now!! i need a plan

scarlemthug

u cant put a B series head on a D series block......

Well u said u were thinking of spending 6-7G's on the engine over the next year or 2 and if thats the case turbo'ed GSR is easily possible.

I would get a GSR swap with an Intake for this year and that should be enough for the summer. Then next year turbo. I dont think u will be satisfied with a D series turbo.

Dr.K

When you go B series your starting with an altogether better engine. This subject is Fiercely debated. A Turbo D might be just a touch faster for the same amount of Money but you are nearing its potential on the stock Internal's. A B18C with bolt on's is pretty much the same performance. But you can do so much more after without doing internal's. Just with cam's and Headwork you'd spank most Turbo D's on stock internal's.

chris_si98

so how about i build up the interals on my d series? then maybe port and polish further down the road?

start buying Turbo parts for your Y8... cuz you'll be saving all this money but be itching to spend it instead of waiting for the swap... you'll end up buying altezza tails, a bodykit that fits like a$$, a bad paintjob, ugly rims and you're still an 18sec car.

your first purchase should be a disco potato... i wish mine was...

Dr.K

Because any "B" motor is still a better engine. you'll be busting tranny's and everythign else with Hectic D motor's. Why not just start with the better block to begin with?. Trust me you won't be dissapointed. It also doesn't cost much more to Turbo a B as it does a D. So you might as well boost a B18. Have You thought about boosting a b18A/B in your car? That would be well within your budget and be faster than the Turbo D or the B18C!!!!

hehhehe, no that wont work..Here man, it sounds to me you need a lot more time in the research process im assuming you're new to the honda scene. Someone already suggested piecing together a turbo kit (that would cost well under $2000)..but look, seriously once you turbo you have to tune, get everything working properly..and face it, things BREAK. And if you're trying to stick B16 heads on D16's i dont think putting together a home-made turbo is up your alley..

Take your loot, do a GSR and as you said..put money into it over the next couple years like you already plan and you WILL have an excellent running car within the HP range you're looking for!

thats my 2 cents!

but if you're into the turbo go to www.turbod16.com, most D16 T's average 170-220 HP getting low 14's to low 13's in the 1/4 mile.

IMO if u dont wanna break the bank but want a quick car ur 2 options are B18b1/gsr tranny ot B20b/z with GSR tranny. If your planning on staying N/A then the B20 with GSR is the way to go, if ur gonna turbo then the B18b1 is my suggestion. B18b1 full swap should run around $2500 installed with all the mounts and misc. stuff u will need and prolly a generic short ram intake. Then u save up another $2000 and put together a basic turbo kit (T3 super 60 turbo, log mani, etc etc) and have it tuned at neetronics for i think another $800-1000 on hondata. With that setup u should be able to push up to 300whp and u will have gobs of torque.

Dont forget though that once u start modifying ur engine ur fuel economy will most likely suffer, u will need to upgrade ur clutch, brakes, tires and suspension aswell as ur driving skill to handle the extra power.

Dr.K

Ok/......A D motor is an economy car motor. A B motor is a Performance motor. Which would you rather start with? A B motor IS better than any D motor. Without a Doubt. Can you prove me wrong with fact's, Or are you jsut going to Post another humorous emoticon to cover up your lack of Knowledge B motor's were in Teg's for a Reason. Becuase people beat on sports car's and B motor's are more durable. Not to mention there much more powerfull in stock form.

Whatever you do to increase the HP (be it swap, turbo, D, B, H, K, whatever), the first thing you should do is target the handling and braking aspects of your car - and it is more than just "lower" your car than anything else.

You will be in a better position if you do up the handling/braking first then up the power as oppose to the other way around. Because stock for stock (same Civic in this case), a Civic with upgraded suspension and braking will be better than the same Civic with nothing but increased HP (say, going from 106HP to 200HP). Going straight line isn't everything and even guys who do nothing but drag racing tackle handling more than anything else.

And believe me, a Civic with upgraded suspension components aren't cheap. It will cost more than a swap or a turbo kit just to make your car handle well as if it was riding on a rail when cornering. You get handling done first, and you can live with the same engine because now, you can corner harder, and brake later which really means, you are shortening the lap time and that translates into "driving faster".

You up the power first, you will find out that your car cannot and will not perform to its best condition without upgraded suspension and braking parts.

Conclusion - you can live with slower speed, but you cannot live with a poor handled car.

Very well put! Amen to that!

You sound like as if no one raced with D15/D16 in other parts of the world. Every engine has its limit. Engines evolved over period of time done with design and research. D is a smaller engine to begin with, therefore, it has its limit in NA form. B with a larger displacement which will do a better job in NA form than that of a D series. Then you get K, F, and J. There are all different engines with different limits. For each and every one of these engines to reach its full potential, it can all be done with knowledge and money.

A well built engine is a well built engine. Anybody can dish out a couple grand and drop a B engine, but not everyone has the previlige and knowledge to build an engine.

Double_B

I see a rebuttle coming soon..................K, Bruno is very knowledgable. As for D or B series, like Nova said, anything can be done depending on what you want. I don't understand this whole D series vs B series thing, who cares! If you are happy with what you got, work with it, if you don't like it then go ahead, swap away, but bottom line, Honda engines are great period!

chris_si98, ask yourself:

1) What kind of horse power range am I after? 150whp, 200whp, 250whp or more?

2) If I want this much whp (xxx amount), how am I going to achieve it? NA, Turbocharge, Supercharge, or Nitrous?

3) Will the engine of my choice achieve the whp I want with the format of tuning? (i.e. Will D16Y8 reach 200whp in NA form? No. Will D16Y8 reach 200whp with FI? Yes ; will B16 reach 200whp in NA form? Yes)

4) What other things I need to upgrade on my car?

5) How much money do I have? Am I going to borrow a loan and go all out at once, or do things piece by piece? Or divide it into different categories and target each one in different stages?

Good luck
