capri xr2 motor swap
 

hey guys, tried searching for mercury capri motor swaps but all ive found is information from the b6t in the 323.

so i really want to do a b6t swap :idea: but i am on a very tight budget. it will be less money than finding my own parts for a turbo setup, and tuning it (voodoo box is like 400 bucks or more.)

i can get a capri xr2 motor right now for about 350 (hes asking 500 for engine and tranny, has 142k mi so i will replace all gaskets and do tune up.)

engine/tranny 91 capri xr2

the b6t in the mercury capri looks like it will fit without having to fabricate anything, probably just repositioning the intake from the turbo, but thats just from me eyeballing it, ive never seen a oem mercury b6t in person. it also looks like less work than getting the b6t from a mazda 323.

if the motor wont swap without fabrication, do you think i could just buy the turbo setup, injectors, MAF, and ecu (and connectors) from this guy and have it work on my b6?

thanks ppl.

So youre on a budget and you want to do a swap?? What is your power goal?? Im not against it but you can get 250whp out a miata 1.6. Also why a voodo box when you can have a MS for the same price, if not less.

yeah, as long as i can get a job i could do anything id like to this car, but like i said i have set aside some money for my car which is my budget. i have seen swaps and engine builds on budgets so its not like its impossible. anyways, my power goal is anywhere between 180-260hp. i dont want to go all out on this car unless i did a 2jz n/a or gtte swap, which is looking to be extremely possible, (just saw that 2jz swap thread.)


i am well aware of the possible power of a miata 1.6L, but i have no money to diy a turbo setup and tune it let alone buy a used greddy setup for 1k.

this motor is in my price range.

id prefer the voodoo box because like i said, im not trying to go all out on my car. the voodoo box is definitely easier to use. i watched my friend use the voodoo box to tune his turbo miata. (*edit* i also thought the voodoo box was the cheapest way to tune the miata, but i have also considered an apexi safc, but i have heard bad thigns about that.)

i am a beginner to tuning/turbo's so i dont need anything thats going to be overkill to my knowledge (flamesuit on.) i'd much rather have a oem tuned ecu and oem turbo setup. makes it much easier on my part.


so do you know if it will swap or not?

Haven't heard of anyone doing that. You're going to have a hell of a time wiring in the capri ecu. But why the F would you do this? Do not blow $500 on some POS 140,000 engine. For some more power do a 1.8 swap. THAT we can help you with. Save your money till you have enough for a proper setup.

The Voodo box is easier and cheapest way to tune a miata??? and youre considering apexi safc over an MS... WOW FTF!!!!!!!!

Seriously I would not spend $400 on a shit box. For you power goal I would stick to the B6 given that your speaking in crank power when you say 260hp the B6 is capable of 250whp. Also if you look hard Greddy kits go for as low as $400 at times, along with other great deals on the FS section.

Besides, doing a swap always includes minor bullshit that at the end it adds up. Also does the miata tranny bolt on to the engine your looking to get??

If youre on the budget keep it simple.

Screw the swap. Megasquirt can be built foor under 400. And that's a fully standalone ecu. Not some shitty bandaid. You haven't told us your budget. I know people have done diy for 500.

He's looking from 180-260 hp that is well within the range of the 1.6, theres no need for a 1.8 swap. Also with another $500 and good research he can have a set up that can get him to his goal

Well he kept saying he didn't want MS. I don't entirely blame him, if you're not computer savvy or looking for massive power, it's not necessary. A 1.8 could be done within his supposed $500 budget, and retains his factory tuned ecu. If he's not looking ultimate power, it'd be a decent hp jump. His light weight chassis would make the most of it.

well, im an auto student, i am great with automotive electrics, soldering, and reading wiring diagrams. i have Mitchell On Demand 5 at my fingertips so i can get any information about any car id like, including wiring diagrams. i dont think getting the capri ecu to work in the miata would be that big of a challenge, why do you think that?

im trying to do swaps people wouldnt consider first since originality is a key thing for me, i dont like to do things others have done, that would just make me a follower. also i disagree with the 1.8 swap because the same power can be had in the 1.6 that im aiming for.

my miata motor is the piece of shit, it has 200k miles and runs like ass.

i normally wouldnt swap a motor with 100k miles or over, but miatas have a b6 motor, capri's have a b6 motor. why wouldnt they be the same in the reliability-under-boost department?

its 1.6L 4 cylinder from mazda, we arent talking about a boosted saab or audi..

anyways, all i want to know is if it will swap without modification??

p.s. i could definitely live without the discouragement here because i can think of a million reasons why not to do the swap by myself, im not incompetent.

If you wanna do a swap put in a FE3 (2.0L)....I think stock n/a they have around the 160hp mark and when turbo'd they can put down some serious numbers. That and from what I have read they are very stout in stock form...

Ok then knock yourself out. Post pics once youre done.

Do the swap if you want, I'd want a 1.8 if I were going through the trouble. You say you can get your HP goal with the 1.6, which is absolutely true, but the 1.8, all other factors equal, will spool faster and have more torque, and you also get the availability of the higher-flowing '99 head if you should find more money. [/runonsentence]

You also said you can't afford a used Greddy, but you're aiming between 180-260. With what your budget seems like, I'll e-high-five you if you get over 180 hp.

i dont think i need to quote myself in saying i am a beginner at turbos/tuning. i dont know anythign really about tuning and have only elarned how to tune a voodoo box. I have not seen a MS go for less than 500. i do not need a standalone for the power im looking to get.

a member on the forum suggested i get a bandaid for basic boost. i intend to do so.

i suppose a oil leaking, overheating, bent valve, and overly abused miata b6 is better for boost.

lowest ive seen is 900 incomplete. ive been looking every other week, maybe i need to look harder, which i will try to do.


this is the type of question i intended to be answered. if anybody has this information i would like to know the answer to this.




standalone ecu requires dyno money + tuning money i dont have. i know how to use a voodoo box, and if i were going to get a turbo kit instead this is how i would do it, THEN move to a MS.

thanks, this is correct. i have tried the turbo setup option, and it it is on the top of my list, i have already discussed turbo options with other members and would like to not have this be a unintentional double post.

im just trying to figure out if this swap can be done, how hard of an answer is this to recieve?

thank you.

i am looking for boosted power, N/a doesnt nearly excite me as turbo power does. i bought the miata with the intentions of boosting it.

Different camshafts, pistons, rods, crank, possibly a different bolt pattern for the transmission. Hell, there are enough reasons to swap in a head from a manual car if you're turbocharging a automatic miata, whether or not you're keeping the autobox, there's bound to be countless differences going between a FWD Ford and a RWD Mazda. Mazda engine or not, Ford is still the one that installed it, not Mazda. They could've asked for a completely different engine mount design from Mazda, who knows. Guess you'll find out.


No.

that is what i would like to stop at. if i do piece together a turbo kit, i would like to go with the voodoo box for now, learn to drive my miata under boost, upgrade to a MS standalone. then upgrade my turbo and fuel system. then you can e high five me when thats completed probably next year.

*edit* my miata is manual, curly. and i am looking for fact based opinions on why it will not swap. the 323 b6t swaps without having to make an adapter plate, it is a fwd engine (requires other modification though).

you cannot tell me i cant do it just because its a fwd motor. i am looking for actual differences between the mazda b6 and the capri b6 that i cannot do this swap.

Thats one hellavu reply right thurr....:laugh:....just so you know it seems like your comin out swingin, people on this forum don't usually aid those that come off that way, especially when they have 26 posts :giggle:

There you go my 0.02

i did not intend to post like that, but i had a lot of posts to cover, and did not want to double post, as general forum rules point to avoid double posting.

i recieved a lot of information that other members and i had already covered in another thread, as seen here: https://www.miataturbo.net/forum/t35157/

buffon01, i havent seen a miata motor go for 200. ive had a thread in the classified section for over 4 months asking for a 1.6 motor for about 500, couldnt even find that, ive searched and even in old posts havent found a motor for less than 350 bucks. but its possible, i will not doubt that.

i have a sr20det t25, thats the closest i am to a turbo kit at the moment. i have seen greddy manifolds go for very cheap, but all of this time im wasting sourcing together my own turbo kit i could be installing this motor. as you say, i can find all of this if i wait, which i really dont plan to spend more months doing.

If you're for sure boosting your miata, and are eventually planning on going MS, I think most of us would suggest doing that first. I know it's a lot to take in, but you'll learn quick, and it's a much better plan than adding MS later, I know this from experience.



NO ONE ON THIS FORUM KNOWS ANYTHING 'BOUT SWAPPING A CAPRI MOTOR INTO A MIATA.

i was just asking. it was a question i came across when i figured out the capri has a b6 motor. ill find out for myself.

:facepalm: what would the advantage of getting that POS swaped?? give a reasonable answer and I'll stop busting your balls. :vash:

Dude, do some reading. Look at p51's build. He was super budget. If you've got a t25 why not just get another cheap 1.6 or even 1.8 and get a mani and downpipe? IMO if you're going for budget, stick with something that's been done and there is support for. Oh and I bought my Greddy kit brand new like 6 years ago for a grand. You can find them cheap if you stalk the for sale section.

Sorry about being so IN YOUR FACE about it, but I had to get the point across. If it's originality you're after, a Capri motor swap is your answer, but just know we have no answers currently. Good luck.

If you really want to swap a capri motor in your car, go for it. I figured you want some input from people who have turbo'd these engines. The parts for the MS are like 300 dollars. Solder it yourself. Whatever you do good luck on your quest. (no e-thuggin intended)

theres no reason you should be busting my balls, i asked a simple question, if anybody knew anything about the capri motors and their compatibility in miatas. thats all i asked.

i appreciate the alternative feedback but really, i bought the car witht he intentions of boosting it...therefore,

have already learned that sourcing out a turbo kit is a good possiblility, even on the cheap. which is why i bought the car in the first place.

if you really must need a reason to stop busting my balls, it has a OEM turbo setup, it has an ecu that is tuned for the b6 motor under boost, no need for standalone or bandaid, less miles than my motor, runs unlike my motor, is cheaper than sourcing out my own kit and tuning it, they go very cheap in junkyards (same price as a miata b6) would be easier to upgrade since the motor is already boosted.

i have seen his build. i havent ruled out sourcing my own kit. its first on my list, i just wanted to see if this was an option.

im going to find the answers to my own questions the hard way. ill come back once my miata is boosted, or the motor is swapped.

Whatever, good luck.

thanks.

I'll just provide some clarification here.

The block and head are the same and will just drop right in if you switch out a few things, most notable the CAS and the manifolds. I'm just talking about the bare longblock here, I make no promises about accesories. Any way you spin it though, you WILL need a new exhaust manifold/downpipe/turbo because it is currently set up for FWD and the turbo is facing the wrong direction.

The ECU wont work, it relies on a distributor and therefor wont work with the miata ignition system. The voodoo box is a waste of money. If you are good with wiring and soldering as you claim, you would have no problem putting together a megasquirt for something like $250 dollars ( no bullshit here, I'm pretty sure the grand total on the one I built for my friend was ~260 with some extra options).

There are some good reasons to do this swap, 7.8:1 compression being one of them. Running compression that low will allow you to run a stupid amount of boost on pump gas. On a good tune, you could feasibly have a fairly reliable car in the ballpark of 260whp. ( But without a megasquirt or some other "real" form of engine management, you wont even come close to being able to take advantage of what that motor would be capable of).

You want to drop in a "turbo" motor, but its not that simple. With all of the parts you would need to make this work, you are basically buying about 90% of a turbo kit. PLUS a motor. It would honestly be cheaper to just save up and get a BEGI-S or a Shanghai.

thanks for being the first person to accurately answer this thread correctly.


i had a feeling that the turbo wouldnt be facing the right way. wouldve been the same story if i had done the mitsubishi mighty max > 4g63 swap, except that no modification to the intake manifold wouldve been necessary.

now i at least know that this swap is not possible on my budget, at least it can be done, but with modifcation.

again, thank you for this post, had someone answered with a post like this i wouldnt have spent so much time answering and arguing about shit i already knew.

like i said, i will be back once my miata is boosted. (or if i do a 2j swap, since that looks to be very possible) i dont want to deal with shit like this, i was asking a simple question.

You could whine a little more if you want, I'm sure that will help :)
