Hey all, im somewhat new to the Honda game and i got a 94 del Sol Si with a d16z6 engine. Its got some work done - i/h/e, chipped ecu, etc.. but she's comin up on 200k now and im weighing out some other motor options. So heres whats im stuck on, either buy a new z6 and build it for boost or swap in a b20 and give it a mild build. I'm pretty mechanically inclined but this will be my first swap and i just had a few questions to ask that i couldn't turn up in any searches. BTW this will be my daily driver and im not looking to make any crazy numbers, just have a nice fun to drive reliable car with a lil extra kick...
I'm guessing this is what i would need but if anyone sees anything that seems outta wack or that would work better please let me know.

b20 route -

*B20z block
*94 teg ls axles
*ls or hasport mounts
*b-series obd-1 dizzy, (not sure which would work)
*ecu??
*b16 tranny
*appropriate shift linkage
*wiring harness?? (i want to make this as close to plug-n-play as possible without hackin up wires)


turbo d16 -
*prob end up just buyin a turbo kit
*vitara pistons(or comparable)
* forged rods


I'm leaning a bit towards the b20 cuz its something new plus has some nice tq, but im open to ideas in any direction. Thanks in advance!!

B20Z is a great engine. You can use the LS(B18B1)OBD1 Distributor as well as the LS OBD1 P75 ECU. For the Del-Sol you will need to run the Del-Sol VTEC trim Shift Linkage.

datsol94

cool thanks man, so jus basically switch the dizzy over to make it an obd-1 motor and its almost a drop in? Also, will the P75 plug up to the stock harness in the car or will i need an adapter? sorry im kinda new to this.. thanks again tho

If your del sol is a 04 model you are currently running an obdI setup. As mentioned, the B20Z setup will work wonders in that little car, regardless of which tranny you end up using. After trying a couple ecu's, i'd say go with an obdI pr4.

You can use your existing harness, and you will need a b series del sol shift linkage

vtecveins

the z6 is great platform for single vtec but are you talking b20 vtec or just b20z the b20 vtec puts down a good 190 -200 hp if done right thats plenty for what you are looking for but dont boost that crv/ls vtec the b20 block is known to hold more heat its great for all motor though

datsol94

thanks for all the info.. yea i was thinkin ill just drop a b20 in an rather boost it (cuz i hear they have thin cylinder walls) i'd prob end up goin N/A figure high comp pistons, cams, retainers+springs etc. like i said im not tryin to put down anything crazy just have a nice sporty car thats fun to rip once in awhile. plus i figured a b20z n/a may be more reliable then a turbo'd d16 but i may be wrong.

supra-n-civic

its not so much which ecu it is your using its the year the ecu and car are. obd2 ecus in an obd1 car will need a jumper but an obd1 ecu in and obd1 car will plug right in. and yes its pretty much just a drop in. youll love the b20 im rockgin one right now with cams and intake manifold and hytech header and its nice but still working on it

Deetz

A good old internet myth my friend! The B20 do not have thinner walls, they are just mounted differently

datsol94

ahh i see thanks for pointing tht out. well more then likely for now its gonna be n/a non-vtec. i'd love to build a cr-vtec but being this is my first swap i dont think im ready for anything on tht level just yet haha but dont the road is always an option.. as for the bottom end; is there anything i should look into beefing up? rods, pistons? i was thinking to put in higher comp pistons but if im just building the head a lil and throwin some bolt-ons at it how necessary would it be?

Matt93eg

Plenty of people have boosted B20s and had great success with no problems. From what I have seen its those people that push the envelope or don't properly tune that have problems, and that goes for "any" engine whether it be a Honda, Nissan, Toyota, etc. And the B20 bottom-end is pretty tough, Rods, Crank. However a good upgrade on the LS and B20 are ARP Rod Bolts, but then again, ARP Rod Bolts are a good upgrade for any engine whether it a B or D.

Here's one of my favorite B20 Turbo videos, I really like the 3rd gear pull towards the end.

damn yo tht ***** pretty nasty.. rips pretty nice. i guess i could always run a lil boost down the road if i had the means there was one thing i was wondering about tho, the hubs on the wheel side of the axle- since ill be using LS axles im assuming i would need the appropriate one to accept it and that i cant use the stock ones i currently have right?

Hah I was just going to direct him to that video. It's crazy how he still gets traction while switching to 4th haha.

B20, it's really fun to drive, the torque makes all the difference in the world

b20's are the ****. i took one out of an integra i had bought and i plan on swaping it into my civic hatch.

datsol94

lol yerrp. i havent been able to stop watchin tht vid.. its a pretty nastaye setup any1 noe if he's runnin cr-vtec or jus boost on the stock block?

Your car is DOPE SON!

Matt93eg

No, your Hubs will work fine, the LS axles will slide right into them like your stock Civic axles, gotta love Honda right? So, once your engine and tranny are in, slide the axles into the tranny, then into the hub.

I can't find all the info the owner of the B20 in the vid posted but I do remember that is was not a B20/VTEC, Just straight Non-VTEC B20... He posted his setup here on H-T.

I suggest doing an all motor z6. My friend has a z6 in his hatch, he has intake, s2k throttle body and DC header, and his car is quick and sounds so good. B20 is just going to be too much money with the swap then you have to find the rare parts they have on it since it is a CR-V motor and not a civic motor. N/A is the way to go for a daily driver.

Matt93eg

Your kidding me...right? Building a SOHC N/A is a waste of time. It will take a ton of money to get any "decent" WHP. If your gonna take the time to build a D-Series, build it for Boost, not N/A. You will get way more power per dollar that way. Unless your wallet has an infinite amount of money or you have sponsors to help pay for what your doing. And N/A the way to go for a DD? Boost is great fun on a DD. And as long as quality parts are used as well as a good tune it will be reliable...not to mention fun.

And before people jump in and say I am a D-Series Hater, I'm not. I rocked a D16Z6 for like 4 years and enjoyed it for the most part, besides the lack of low end HP and Torque, it was fun from 5,000RPMs up. But I wouldn't even begin to waste my time nor money building a D-Series N/A. That's just me. I'm also not going on what people say about building a D N/A being super expensive. I did my own research on it around a year and a half ago because I came across a cheap set of brand new P29 pistons and thought about putting them in and building my Z6 N/A. It didn't take long to decide I wasn't going to.

Thts awesome man, gotta love Hondas ingenuity so judging by all the info i've gotten from here this is what i think i need to switch over be good to go, please correct me if im wrong. (this is not including the other components mentioned above; rather jus mods needed to the engine before drop in) LS dizzy- OBD1, LS or Skunk 2 intake mani, LS header? n i think i should be good. Also when buying parts such as cams,retainers, intake mani, etc should i be ordering them for a 94 LS teggy? or the year cr-v tht the motor came out of? Thanks again, you've all been very helpful in answering my questions.

91integra91

what head are you using?

datsol94

stock b20b or b20z. which ever i can get my hands on

DustinRose

i repeat, go B20, b20vtec if you can afford it

datsol94

anyone???

Either a 99-00 JDM B20B or USDM B20Z. Same HP + TQ. If vtec, doesn't matter, you are swapping the whole head anyways.
