Who has done a turbo?

[twintrbo]

Has anyone installed a turbo in their 5? Other than the car magazine Speed5 that is. Just curious about HP numbers and fuel mileage, etc.... I really do love the 5 but another 20 HP would have been great. I'm thinking of adding a K&N filter and from my years in the tuner world, I know that anything past that will cost a lot but not get you much. A cat back might give a little too but I'm not willing to sacrifice any noise since its a family car first and foremost.

I think the ideal swap would be a CX-7 motor, not as much peak HP as the MS3 but better midrange where its more useful.

Funny you ask...I was just talking to my brother and he talked to a guy who lives near by that turbocharges anything they say ( he also tunes everyones cars in this area that has Evo's and Sti's )....My brother gave me a quote of $2700-3000 parts and labor included...I'm going to talk to him personally on thursday. I'd like a little more OOmph! I had all 6 of us in the car and my baby was struggling.

I looked quickly and it seems the CX-7 motor can be had for about $4000 but then you need the ecu, wiring diagrams,some patience and electrical tape. Of course when its done its factory more or less and bulletproof reliable.

$3000 would be cheap for aftermarket actually! Your toughest challenge would be fuel management. It would be a light pressure setup since I'm sure factory internals are not too beefy, maybe 5 Psi tops. Intercooler would be optional too since its a small setup. Larger injectors and a means of controlling them reliably would be the issue here, possibly a larger capacity fuel pump too.

Back to the CX-7 setup, it would be awesome if the axles lined up and just drop the tranny in too! You would need to have a really good look at both powertrains out of the cars to see if it would work but that would be the ultimate retrofit!

The MSP has the exact same internals so it could do a little more than 5psi. But that is a safe setting. An SSAFC would be great as far as engine management and there is a whole library of setups in another thread. The guys there would be able to help with any questions you might have.

 

[twintrbo]

They cant be the same, since they have different compression ratios. Besides this, the speed engines are direct injection not multi port so they can sustain higher boost levels at that high base compression. Most turbo motors without DI have ~8:1 compression.

Another factor here is the SAFC for fuel management. Depending on how much larger you make the injectors, it can really mess with your driveability. The SAFC/ ECU combo in my mitsu does not like the injectors I put in and they are roughly 50% larger than stock. Its not awful to drive but its VERY hard to be smooth and I would not tolerate it in a daily driven family car. I'm not actively considering a turbo while I still have a warranty but I would like to have some ideas for the future

the msp has the same internals as what? def not any of the newer mazda engines thats for sure

edit: and you probably dont even need bigger injectors for 5psi
im running 14psi on my P5 with stock injectors and no lean issues anywhere throughout the powerband

if you could tune the SSAFC then it should work for the 5, you just have to figure out if itll work on automatic cars...not sure if it will or not
i dont see why it wouldnt but ive never seen one on a auto

 

[JMKOOPA]

Not the newer engines silly, he was talking about boosting a P5 which HAS the same internals as the MSP. Read the part about the FS series engine used in the Proteges: http://en.wikipedia.org/wiki/Mazda_F_engine#FS. Yes, the SSAFC will work on an automatic. The fuel injectors are probably the same too. I know a thing or two about the SSAFC and I know for a fact it will handle the larger injectors well. Just gotta put in the time for tunning. I'm running 565cc pinks instead of the 280 stock ones, even though I was told 440cc is the limit for the FTC1. My MSP is fully built and I can up the boost to 26psi with no problems.

 

[twintrbo]

oh sorry I misunderstood the MSP, I thought you meant a speed 3. Then it might be possible, sure! I also misunderstood the SSAFC, I thought you meant the HKS AFC, we call it an SAFC or just AFC on my other forum for the mitsu. You were referring to a specific item.

If its got 280cc injectors stock, it will need larger ones to be on the safe side. It seems that from a converter I used it will need about 400cc ones to make 200 HP. If the SSAFC and the ECU will allow stock driveablilty then its a worthwhile upgrade to make. Especially if you went with one of those remote mount turbos so you didn't need to swap the manifold out for a turbo one.

The only issue here is my wife killing me for thinking about it lol

Tri-point has a kit for $3400.

How did this conversation turn from a Mazda5 with DISI motor into a Protege5 with MazdaSpeedProtege motor?

Thread reading fail.

Your best best is likely an aftermarket turbo kit.
Apparently swapping in a DISI motor turns into a nightmare with the ECU and wiring.

 

[twintrbo]

Unless.......a DISI motor with an aftermarket ECU! Of course it would still be an issue of what would not work afterwards like the tach or speedo, you know, little things lol

FWIW the topic was a turbo on a 5, period. I just speculated on how nice using OEM stuff would be and how powerful it would be with the CX-7 motor. It would really rip with all that midrange.

 

[AIMWO4]

I would think adding a DISI turbo engine, would be a nightmare if there wasn't another car around to drive. Attempting to get all the other bits needed would be a real treat, too. I'd go the after-market route if I were to do such a job.

And I spend a lot of time on my other car. (lol2) An old Triumph...

 

[JMKOOPA]

Yeah, doing the swap to the DISI would be no joke. It would be very costly too since the engine faces the opposite direction than the current P5 engine. But if you had EVERYTHING ready for it then good luck. But yeah, I was referring to the Split Second FTC1 that we use around the Mazda neck of the woods. So just adding a turbo to the current engine and boosting it at a low setting like 5psi would be fine. But just watch out for the mod bug...

 

[twintrbo]

Oh I know all about the mod bug, I have a 500+HP 3000 GT VR-4 as the weekend toy The only way to beat it is to plan ahead and do not deviate. As a co-worker once said, "plan your work, and work your plan."

I had no idea the motor faced the other way, no way I would bother trying that one! No wonder the Speed5 project was such a mess for them to complete! Then its def easier to do it custom. I wonder what 5 Psi would yield power-wise, maybe I should poke around the MSP forum.

 

[JMKOOPA]

Yeah, the mod bug gets you. That's why I have 4 hot rods with at least $10k in each... Oh well. The MSP is the latest money pit but it's something different. There's quite a bit of people that boosted their P5 around the forums so you can just ask them about their builds and stuff. Good luck.

Where is that thread about the school / university auto shop guys and kids that did an Mazda 5 Turbo upgrade with intercooler and EVC and everything ... ??

...end result.... POOR, worse than poor really, you can put a turbo in a fat b****, but you can't take the fat out of her.

...the 5 is one fat ass heavy biotch of a car and the 'added' "boost" will not get you a RX-8 results.

Just saying... read that article.

Just my .02 worth and if you do turbo it, get with Dima, he did headers and such, could be of help.

--PLEASE someone post a link to that thread, it was a hoot (flame2) -- (shocked)

Peace!(rei)

 

[justanothermp5]

jmkoopa, dude your thinking of the wrong car
he is talking about a mazda 5 not a protege 5

 

[JMKOOPA]

Ha, I just noticed that. My fault yo! Been busy at work and not payin attention to what's goin on I guess. That makes things a little more difficult! To my knowledge, there's not an aftermarket turbo/super charger available for it. Best thing to do for now is cold air intake, exhaust, spark plugs/wires, and maybe a few other things. Sorry for the bum scoop man, I wasn't paying attention.

 

[justanothermp5]

lol yea its cool, you had me a little confused halfway through tho, took me a while to figure out why haha

 

[JMKOOPA]

ha, yeah. You said that and I was like, wait a sec.... I didn't even read what thread we're in here. So disregard all of my posts, forget I exist...
