Going Turbo

[MazPro]

well, i have decided to go turbo. the hiboost is way too much @ $4200, so i am going all custom (cabpatch)

I will be going with a GT25. I picked up an exhaust flange from Bkinman on the "other" forums and need to pick up the t25 flange and turbo so I can get the manifold and downpipe made. FMIC core looks like it will be from Turbolife on THIS (http://www.mazdas247.com/forum/showthread.php?t=123678740)thread which is 27.95 x 9.25 x 3.46 (a copy of the perin FMIC) and custom piping.

I am not sure what i will be doing with the fuel, so far it looks like I'll get bigger injectors, an FPR and a walbro 255 just to be on the safe side (110k on the stock pump)

if anyone can chime in with suggestions on how to make this better i'd greatly appreciate it.

Lemme know if you need anything.

I can get most turbo stuff pretty cheap. :P

[k-lea]

What are you going to do internal wise?

[MazPro]

for now, nothing, but I may build it later one. how much are the pistons and rods from you guys? and do they come already machined down to fit the 1.6?

[k-lea]

You might wanna do something about those internals otherwise you are setting yourself up for failure later on. *shrugs* Tis what I'd do. Instead of going through it twice do it once. Be patient with things and allow yourself time/money to do things right.

What I can tell you right now is just what I can view on the site. I have to talk to teh boss0r before I can get an exact answer. I think what we have is just for the 2.0. But I may be able to get something done for you. ;P

Shit ben and the asshole that he is ran a stock ZM on like 18 psi with just a FMU.

You can make good, reasonable power on stock internals with that there 1.6 ;)

I think when it dynoed it was at much less (10psi or something) and was ~185whp ~225 torque! That's great power for a little Protege :)

[k-lea]

I've just seen so many fail that I'd hate to watch it happen again.
Basically what I'm telling the kid is if it DOES happen then he is going to have to go through it all over again because he missed some steps that could have prevented it from happening.

Know what I mean?

Say he gets 190whp or so and really pushes the car. Who is to say the internals will actually "stick" where they belong? I've witnessed a MSP take a fall more than once because the person failed to do it the right way. It's seriously something that isn't fun to go through.

I just don't see someone being happy with 180 or so. You always want more. Kansei, you know if you could you'd push more out of that sucker. You know for a fact! And with a built motor you kinda bypass some steps..

..I derno, I'm ranting.

[kansei]

^^ I could push a lot more out of my car. All it takes is turning up the ol boost controller knob and bam power. My one year turbocharged anniversary is in two weeks and I have yet to turn it up. Without an LSD it's already too much power, it really is much less fun to drive now than before.

All it takes to keep the motor intact is a little bit of willpower.

Your use to FSDE's.
They suck.
Ask rob.

[k-lea]

Ok.

And how reliable is that car going to be after xx amount of time with the boost turned up and you pounding on it? I'm sure it's not going to be too good after a while. If my damn Miata failed on me, his is destined to fail.

[Kitty]

my z5 takes/took 12psi daily (and 18psi when angry) when its not breaking transmissions or axles or motor mounts or rear sway bar mounting points.
and I it tuned by just dumping fuel at all rpms.

it took trial and error to get it to that point though.

[k-lea]

Point is is that no matter what your stock internals are getting a hardcore wear. If you were to upgrade them now you'd save yourself the headache later on. I wish I would have played cool and done that WAY before I started putting more numbers out. It would have saved me money and tons of time.

[MazPro]

I am not worried about the motor going because I know the 1.6 can take a beating, plus I will not be running anything over 10 before I go with a piggy back or stand alone.

i know Witchdoktor got his pistons and rods from kooldino, and he had to get them machined down to fit the 1.6, that's why I'm asking if you can get them already done.

[k-lea]

Well, if you want to do that just shoot me a email: kspeedcircuit@gmail.com
So I can remember.

[KrayzieFox]

The 1.6L is probably the most boost-friendly engine of all 3rd gens as far as I know. Forged internals would definitely help, but they're not a must like on the 2.0L engines. Turn it up past 10 psi on a 2.0L and you're going kaboom after a while, but your 1.6L should be good for a decent amount of power.

What sort of power are you shooting for anyway?

[avarela86]

HOZAY!!! Going to up that 80ish HP demon?! See you at HIN tonight.

[MazPro]

HIN was fun man, your car should have been in the TBK booth.

I am hoping for about 200, but to start, i should be happy with about 150-160 @ low PSI.

[k-lea]

*sigh*

You'll hate it. Haha.

No machining was necessary...I got the forged 1.6L pistons custom made, and I now have a job number for them. If you ever need them, let me or k-lea know.

How much power is he making on the 1.6 with forged internals? Since so few people turbocharged 1.6s there's just not a whole lot of info out there.

[pdhaudio83]

Word... bumpage! How's this build coming?

[kamon8404]

Curious sub ... I am a huge fan of small motors running boost and making good numbers. V8 owners FTL.

[Z]

i dunno if its true or not.....but i heard that the 1.6 can take upto 16psi w/ a good tune on stock internals.

[BRIAN MP5T]

^^^ Ummm, I wouldn't do it to my car.... LOL

[kansei]

I've seen them take more than that, reliably, for years, on a stock ECU + rrfpr :P

yeah man, there's a good reason people call the BP bulletproof :D

[kansei]

yeah man, there's a good reason people call the BP bulletproof :D

you mean ZM? but yeah the Z-series sorta evolved from the B-series

[pdhaudio83]

oh whoops, haha we're talking about PROTEGES.

durdurdurrrrrrr

[SATimko]

Subbin to see what happens.

[MazPro]

from what I have seen the ZM is a pretty strong motor. I have a video that hiboost made on a stock 1.6 with their kit and 2.5" exhaust dynoing over 260 @ the wheels with everything else stock.

so I've been thinking and talking to a couple of friends and it really does seem that the GT28R would be the best bet for me. also, i am checking the price from hiboost for the manifold, i read on 247 that it should be around $350. if it is I will probably be going with that since it would cut the cost of a custom tubular manifold by a LOT, that is if they still make it with the t25 flange.

So here is the list of the parts that will make up the kit:
hiboost turbo manifold
Garrett GT28R Turbo
hiboost DP (depending on size)
BEGI rrfpr
FMIC Core from 247 and custom piping
o2 clamp???

those are the main things, Im also going to do the timing belt, water pump and a couple other things to get the car running good. One question can someone explain what the o2 clamp does and why it's needed? I understand that it changes the signal, but why does the ecu need it?

[MazPro]

BTW, here is the dyno of the 1.6 protege...

[KrayzieFox]

The o2 clamp tricks the ecu so it delivers proper fuel supply under boost, when the juice is most needed. Otherwise the stock ecu settings would lead to an extremely lean A/F mixture. I think .. someone else should probably step in and clarify lol!

[MazPro]

cool, that is what I thought. I pmmed thegoldpro and he said he never ran an o2 clamp, just the rrfpr so that is what I will be doing.

also, I talked to manuel from TBK, Juan's brother and he said the hiboost manifold is for an IHI turbo, and he said he can't get me one with a t25 flange so that is out of the question now. I'll also be running the miata's 330cc injectors from the 1.8l.
