alright so i know im going to get flamed for this and that im not smart when it comes to searcing... but let me start with saying im new to engine swapping, let alone cars alone... i have a 91 crx, my fav. place to shop is the local junk yard, so recently i found a prelude with a b21a1 engine in it and an integra, w/e motor was in the years with flip up head lights, 4got to check code. alright, so i want to do a motor swap... i figure i can get either one of those engines for relatively cheap from this junk yard, so i want to know what engine is easier to swap, what engine is faster, can either one be done... what do i need from the car, and what do i need to get aftermarket...

im sorry...

 

its alright, this isnt such a terrible question.

your on a buget and your trying to figure what cars you can yank a motor from for you crx.

that prelude motor is useless. theres no mounts you can use to help get the motor in the car. wiring would not be fun, and theres no aftermarket support for parts either.

youd need to specify the engine code of the teg motor for me to tell you more.

if its a d16a1 (brown top) then it wont bolt in. youd have to weld.

if its a b18a1 you can use it, youll need to buy motor mounts and a shiftlinkage.

basically answer these questions:

1) What engine is in your crx now? (si, dx, hf)
2) How much are you looking to spend?

 

well ill answer the questions of what motor is in the teg. later. ill try to get to the junk yard today.

my crx has a d16a6 block, and a pr3-2 head, with mpfi. i have all peices except wire harness for dpfi swap.

im looking to spend hopefully less than 600... im thinking i can get everything i need out of the car for relatively cheap, what all do i need from the teg. i could probably ask at the junk yard today how much they would want for all the parts.

also how much oh a hp gain would this give me? is it worth it or am i better off just keeping the engine i have now and doing the mpfi swap and getting bolt ons?

 

wait. your car is already mpfi and you've got a d16a6 in your crx now??

 

This what's going on.

86-87 Teg, forget about the engine, that crap only fits in 84-87 Civics/CRX. 88-89, same as DOHC only weaker (less comp, weaker cams). Bolts right in, plugs right in.

B21 engine, might aswell throw that crap onto the river and use it as an anchor for a top. A weak engine, it's an overbored B20 which are known to have weak piston rings (the B21s). To use this engine, you need a mounting kit, more money then the engine is worth.

no my car is dpfi, but i have everything i need to do the mpfi swap, i just need a wire harness. my car was originally an hf, but the previous owner must have done a motor swap, and i have no clue why he didnt convert to mpfi, i think he had a z6 he was going to put in that he traded in with the car, but i was stupid at the time and did not buy the engine with the car...

so if i understand you right your saying if its from an 86-87 then it wont bolt up, if its from an 88-89 it bolts up but is not worth it, and the b21 is completely a waste of money.
do i understand correctly?

 

No, the 88-89 is worth it, but don't expect the 130 HP that the DOHC ZC gives, expect about 115hp. Your D16A6 gives 108, but less torque then the D16A1.

If your car is an HF, the HF is MPFI from factory. If it's DPFI, you have a DX, not HF.

Do NOT use another cars wiring harness, that's a big no no. Unless you want horrible wiring issues, go for it, but just so you know, the wiring harnesses are different from model to model, year to year.

It's easier, cheaper, and better to convert your wiring harness to MPFI if it is DPFI.

The B21 is a waste of money, it makes good power, but it's a weak engine. I'd rather throw in a B18a1.

no,,the 87-89 teg d16a1 does not bolt in to your car,,,,,well it kind of does just need to make a driver side mount and rig **** up.....The black top Dohc zc bolts right in though.......yeah those prelude b20,b21 engines are a waste of time....

also how do you have a b16 head on a d16a6 block? pics?

oh and Hf's come stock mpfi so you probably have a DX

 

yea sorry my bad, i probably have a dx, yea its very obvious that the previous owner must have had a si that he has swapping peices off of, because i know my car is not an si because it does not have the stock sun roof, it has an aftermarket peice of **** pop out sun roof, but i have the si seats, si door cards, d16a6 block, i guess he never took the time do to the mpfi, and i just took a picture and check the head is deffinately pr3-2. alright...



also you can see how my set up is now, headers, and air intake, air intake will be made cold air as soon as i do the mpfi swap, and i have exhaust, am i going to have more power with the set up i have now or with the integra engine? im guessing the air intake and headers will not bolt onto the integra engine and i dont have the money right now to afford headers and a new air intake.

 

are you sure? PR3 = B16a head dohc vtec ...that is definately not a b16 head in those pictures...


air intake can be made to fit..the headers will not fit if its the b18 integra engine..But they will fit on the d16a1 integra engine..

the mpfi setup doesnt really add that much power..maybe 10-15hp with the si ecu and everything running right...but it gives you a better platform,more responsive,better gas milelage,etc...just overall better


the integra at the junkyard..what year is it? (so we can tell you what engine's in it(

 

You are close to me...I can help you out if you really want and i can probably get you a decent swap, I have B18a1 and may have a cable tranny for it soon too...I really wouldn't waste the time with the older teg motors since you could do a mini-me and mpfi and gain the same amount of power for a lot less of a hassel...i wouldn't mind giving you some help, and then i can take you for a ride in my 91 CRX Si w/B18b turbo and make you want to swap in an LS

 

i dont know my integras, so im not sure of the year, all i know is it has flip up head lights.

and i am 100% positive that the head has printed on it pr3-2 i tried to take a picture of it, but it did not turn out... i dont know anything about them so i dont know what i should be checking but i am 100% sure it seas pr3-2 unless im having issues reading...

is it possible that its a pr3 with a different valve cover on it... i dont know...

i would really like a better swap, but im on a very low budget... i already only make about 700 a month and have at least 400 in bills... and gas is about 40 a month... dont have much money to spare... and im getting less hourse at work soon also so im going to make even less...

im just looking for something cheap to do... hopefully all together less than 700... if thats possible...

if anyone knows where i can get better let me know, you now know what i would like my limit to be...

ok flip up headlights is the older one with the d16a1...its really not even worth it to swap that motor in my opinion...

I guess you dont understand the pr3 thing...This is a PR3 head ..B16 in my rex old *** picture



The stamp on your head should say (and does say)PMxxx not PRxx

 

and no i dont understand anything... lol. i just know it has stamped pr3-2... can anyone tell me what kind of head that it? i was told its from a 92-95 civic dx... is that correct?

and so according to you i guess there isnt anything work my time at the junk yard then... oh well...

PR3 head is the dohc vtec b16 head....there is no way your head says pr3 on it..I'll bet you $3500 ....

if Mr.speaker says something, you can almost guarantee that it's fact. he doesn't typically post unless he's certain.

 

alright, so i just checked for the like 5th time... and the bet is off... alright... so what... so i tend to not be able to read... its pm3-2... sorry much... i just went out there expecting it to say pm3-2 and sure enough it did... my brain is messed... i could have and did swear that it seas pr3... w/e so now we all know how messed up i am...

so can anyone tell me what thats off of anyway? what year and model?

Word i can hook you up I can garuntee you can do an LS swap for $700 or less but you gotta look out for some deals

But either way i say Mini-me and Mpfi is your best bet for your budget, SOHC vtec heads are usually $150 or less and you said you already have the stuff for the mpfi and i have some stuff if you don't that i can hook you up with and maybe look for an si tranny if you don't have one, those mods will make your car a little quicker, i like working on cars and I can also weld so you should get to know me better

haha just let me know I'm will to help you out man

 

well... i dont even know where to start looking for stuff... what cars do these parts come out of? if at all possible i would like to get w/e i can from the junk yard, i think there is a new integra at the junk yard as well... shuved back in a corner somewhere though...

also where can i look to see what tranny i have? its possible i have an si tranny... not sure... where do i look for the tranny code?

and still want to know what a PM3-2 comes from.

 

Well LS swap would be from 90+ Integras the tranny would be from a 90-93, mounts and linkage would be custom but you can get rubber stoc like mounts for about $150 and linkage can be made from 90-93 integra linkage, there are plenty of odds and ends that can nickle and dime you but if you know what you are doing or know someone that does you can get the swap done for fairly cheap

As for the Mini-me you would find the head on a 92-95 civic si and ex (D16z6) or a 96-00 civic ex (D16y8)

As for the pm3 head I believe the d15 Dx motor and the D16a6 motor have the same casting for the head so it may be possible it is a full a6 motor but thats from what i just looked up quick on pm3, i sold my a6 so i can't go look at it and tell you...if someone has link for the head casting codes post it up becuase google didn't help me much

Si trannyis labled L3 but so are the other trannys too, I think the only way to tell is if you remove it and mark the the diff and turn the input shaft, there is a post about it, you may also tell by what rpms you are in in certain gears

This right here is true..you can get b-series swap mounts for $100 brand new..for the linkage you can cut and reweld the one that comes with the swap...By me no one seems to want the ls motors anymore,,they want all this k-series stuff and type-r this,,b16 that..etc....so you can get a complete running legit obd0 ls swap for like $400....Thats engine,tranny,ecu,and what ever else you need take it,,T bracket,radiatior,linkage,axles,brakes,,,whatever you need on the front....Thats $500 right there...after a new waterpump and timing belt non oem thats about $60...new clutch off ebay for about $120....THats about it...labor is free....you already have the mpfi parts....

 

alright, well im going to go to the junk yard today and hunt down some hondas, im going to take a note pad and write down what i find. ill post up my finds later, i know there are some mid 90 civics and intagras there. so i will see what i can find. ill write down all the engines codes.

from what i hear, i think with my little expericance i think i may just go with the mini-me swap, since i wont need to be doing any messing with mounts...

goodluck man,,,look out for the 90-01 integra with the b18b and b18a1 engines,,,the 92-95 civic ex and si with the D16z6 engine,,the 96-00 civic ex with the D16y8 engine

 

alright ill keep an eye out for those engines. thanks for all the help and not flamming everyone, i really appreciate it. im getting way better responces then i expected
