HEY
I own a 1990 honda civic with a stock d15b2... aka shitty motor. I am thinking of ordering in a jdm b16a. I want do do a complete build up of the motor but cant find any recipes for some good horse power. Im also going to put 18 psi of boost through it so i have to lower the compression ratio a bit. ANY SUGGESTIONS WOULD BE GRRREAT!!! I'm mainly into muscle cars and when i beat friends they say its not fair(all in imports) so i wanna build an import and show em ill still win
haha thanks

oh and i was wundering if the b16a would bolt to my existing mounts or not????

 

ANY b-serries motor Requires Aftermarket mounts, I would Suggest Hasport mounts like anyone else would.

ALSO requiring Shift Linkage, hasport has EVERYthing you will need to physicly get it into the car.

Is your car a DX?

 

Yeah its a dx. Someone was telling me the b16 would bolt right up.
Oh.. would the tranny from my d15b2 bolt up to the b16???

 

He said its a d15b2 so yeah its a dx..Which means he has to convert to mpfi..And dont build a motor to handle 18psi..Build a motor to handle the hp you want to make ..because 18psi will be different with different turbos so dont use that as a reference..

No cant use your tranny..Must use a b-series tranny..If you order the full swap it comes with a cable tranny already

 

well, the b16 won't bolt right in, you need mounts like hasport or something. you need custom shift linkage, or you can buy hasport if you use their mounts. you will need to rewire your car, because it uses a different type of fuel injection, and it has more sensors and vtec.

18psi?

have you ever considered a different motor? such as, for example, an ls/vtec, or a crvtec? (lsvtec is the integra b18a or b18b with a b16/gsr head on it, and the crvtec is the same thing with a crv block. the crv block is pretty much the same as the ls block, except it's bored out to 2 liters, but it uses different sleeves that are supposedly not as strong. or you could go with a b18c, depending on the money you wanted to spend. there are a couple b18c's, like the c1 and c5. (i may have these switched, if i do you'll realize, don't kill me, i just woke up) the c1 is out of the gsr and the c5 is out of the itr. the c5 is a lot more expensive, but it is close to the c1. if you're gonna build it, get the c1 as you lose all that's special about the c5. the difference between these two motors and the ls motor is a rod/stroke ratio. the b18c's are a lot better for revving, and the b18a/b is great for low end torque, but doesn't like to get too high in the revs.

sorry if this got long, but i just wanted you to know that theres more out there than just a b16a.

 

Oh ok thanks

well the reason for saying 18psi is because i need to find a good compression ratio to run with that any suggestions????

 

The reason for the b16a is because its the most affordable set-up i know of. an easy 160horse to build off of i thought anyway. if there are any other suggestions for affordable motors let me know. oh and forget the whole 18 psi thing. what i meant is the turbo im getting has the cabaility of boosting 18 psi. this will be an every day driver so what kind of boost should i run?

bumpadi bump bump

 

You may be better off just getting a stock b18a and boosting it..It has a lower compression then the b16 and is alot cheaper..You can go to any junkyard and get the whole swap pretty cheap ..Do your basic stock rebuild or maybe get nice rods and forged pistons,,??It would be alot cheaper this way..Not to mention the b18 has more torque and can spool a turbo faster then the b16a..

 

Really? awsome.. what models can i find that motor in????

Well heres the setup im considering now....... B18a with stronger internals(pistons, rods) the turbo set up and get some cams and maybe a computer mod. what kind of horse power would you think im lookin at with that setup

 

bump

 

A b16 with a good quality custom turbo kit and some forged internals is easily capable of reaching 300whp and beyond considering you've taken all the nescessary precautions. You can run relatively low boost on a stock setup, but if you want to move to high boost you need to get forged internals and lower the compression ratio to around 9.0:1 or so.

The B18A can be found in 90-93 Integra RS, LS, and GS. You'll still need the aftermarket motor mounts, shift linkage, some type of modified wiring harness, and you'll need to convert to MPFI. Do a search for the specifics on that.

 

Awsome stuff man thanx

Im undecided now if i should go with the b16a or the b18a... hmmm i cant seem to find anything for a b18a but the b16a has parts everywhere.. any suggestions??? if i went with the b16a would my axel/cv's still fit or would i need to order special hybrid ones?

 

bump

 

Is anybody familiar with jazzproparts.com??? if so hows their service? they say they're motors have an average of 30, 000miles but i find that hard to believe. They have a b16a package that comes with new mounts, tranny, wiring, linkage, ect. for $1600.00 what do you think of that?

 

New mounts dont matter for your setup because it won't bolt into your car.

Your wiring you'll have to get from http://www.rywire.com.
Us (rywire) and Hasport are the only ones with guaranteed harness conversions. You send us your DX harness and the B16 harness, and we make your DX harness work with that B16. There's no other way around it.

You'll still have to get Hasport mounts.

I would use http://www.hmotorsonline.com for an engine.
ALOT and i mean ALOT of these engine suppliers online are just taking orders, then getting the engines shipped over.. so you place an order and they say it'll be 2 months shipping.
You want a place that overstocks engines in the USA, like HMotors.

And most engines are rated to 30k because in japan, you basically can't own a engine with more than 30k miles on it. So yes that milage is more than likely true.

Read the FAQ thread here and learn how an engine works before you consider turboing or building an engine. If you don't have the knowledge to know what parts do what inside the engine, you can't really build an engine. Please do your research.
PSI applies to boost, not to cylinder compression ratios. You need to read more, post less

And whats with the multiple screen names?

 

Hey thanx for the info. why would i need to modify my wiring harness??? the b16a package im looking at comes with the ecu and wiring so as it sits it is a running system. i would just have to set it up in my car wouldnt i or is there something im missing? Im still learning about fuel injected cars so bare with me. And i actually have built quite a few motors and understand there workings so dont worry. im just trying to become more familiar with hondas.

Oh, and by new mounts i meant they are designed for putting a b16a into an 88-91 civic

so japan has a 30,000 limit? thats kinda convenient lol

im using multiple screen names because im limited to 5 posts per name(i just heard of this site no to long ago)

So anyway would i need custom axels or what?

 

Dude PLEASE search. There are a gazillion how to swap a b-series into a crx on the internet. Every question you have asked can be found with the search button. And with regards to the turbo, do the swap and get it running right before you even consider turbo.

 

LOL WHATS THE POINT OF THIS SITE THEN?

I would rather talk to people who have experience with the subject than search the web. thanx anyway man

 

So anyway.... anybody else know of a good setups for hp for a b16a

 

New cams....Itr Intake....Ctr Exhaust....or vice versa...
Toda retainers/springs/lifters
You can get higher comp pistons....like Cp pistons or **** liek that.
Remember the crx isn't known for having HUGE numbers....it's the power to weight ratio that makes our cars so quick...

Ys-1 transmission! It doesn't matter how much horsepower you have. with a good tranny your motor will fly by the comp.

 

Thanks for the reply!

Do you think lifters, springs, retainers are necessary because Ive been told the head on a b16a can actually wittstand quite a bit of horsepower(250-300)
Ive been told by some experienced ppl that i would only need to upgrade my pistons and rods but i dunno

 

I can't seem to find the link but somewhere on here there is a link that tells you step by step how to do a B16a engine swap. After that you can start buildig for turbo. I would personally take it one step at a time and worry about the swap before you worry about what mods you want.

 

Hey

Yeah i agree with that 100%. My main goal was to get a parts list for the final result i want and figure an overall price. Plus to see if anyone has any proven ways to get horse power out of a b16a so when it came time to modify the engine i had an idea on what to buy. it would also be nice to put the right pistons and rods in before i mounted up the motor so i just need a reccomended compression ratio that will work with turbo
