I'm not doubting the possiblity of a turbo SOHC existing. Anything is possible, but I happen to know the way Protoss is, he also comes up with crazy ideas and he attacks tuning with more of a scientific angle. I also happen to know that he has a good amount of wrench time. If you want to, just come a little north to the NYC area, there are a few turbo proteges around here.

Anyway, we did forget some very important points here......

1) Is the motor in a Protege or 323?
2) Is it a track car or is it street driven/daily driver?
3)PICTURES!!!!!!

 

dude...if you are running 12's, good for you. if not, then what the **** are you doing talking ****. you cant impress us. we have all been around these cars enough to call bs, and i have to throw down the bs flag bro

 

haha i keep my mouth shut on the post ...... but if u somehow manage to beat the gtx have fun against the gtr haha

 

lol, ok fine. i used to have an SOHC. i know how they work. if you want to dump money into one fine. but a 12.7 sohc

look the flow of a sohc head is awful, You will NEED a cam regrind. the intake manifold is not boost friendly, you will have to run a stand alone, the tranny wont handle any power above 180BHP.

I'm calling you out. i know what the B8-ME can do. I tuned one. i moved on to a bigger and better engine. The BP-ZE. Look you are being retard, you are fighting a losing battle. and yes I know what i am talking about.

if you can prove me wrong, then do it. i want pics.

 

If you guys can read and understand my language ck out the mazda forum at www.carrito.net

 

the ECU is OBDII a very old system. but a the FMU is burned not programed. like a CD you cant rewrite over a burned CD. expecially a 10+ year old CD. and the FMU is what tells the injector how long and when to spray. to run a turbo on the SOHC you would need a piggy back. the engien will be run with a stock ecu but it NEEDS the help of another system to open the injectors for longer while under boost.

In over simplified graph n/a fuel map is a portionally square function, a boosted fuel map is a partially quartic function.

in reality a fuel map for a n/a is 3D while a boosted engine is infact a 4D graph. remove the temperature variable and you get a 2D and 3D graph.

this is why a stock 90-94 ECU WONT work with a boosted engine without help.

 

hehe on another note i'm glad to see other puerto ricans on this board, as for the sohc turbo doing 12.8, hey i'm not saying it could and not saying it can't just like to know if the car is for track or daily driver, and is it a protege or 323, and another thing wow if the gtx only does mid 13's, then thats garbage, a protege with a stock kl-ze does about mid to high 13's and once turboed forget, just goes to show me that a turbo v6 is the way to go

 

it is very hard to turbo the KL, and you are matching 180hp vs 200.

the KL is a diecast aluminum block. it doesn't like boost. and to boost that engine you are looking at a HUGE budget. you cant boost over 10psi with out sleeves. and then you need lower compression pistons, the geometry of the engien and the size of the engine bay leave no room to fit a turbo.

 

**** you should be able to see that you have one in your car....

if uou were to boost it i would say a TT with small turbos would be the best bet

 

actually by relocating the battery you are left with ample room, as for the twin turbo that set up sucks because for one your left with more heat and more turbo lag, as for the kl engine its actually very boost friendly, stock internals can handle 114psi stock before you have to go into internals, but with that engine 10psi is enough because at that amount of boost your already doing about 282 to the wheels, if you don't believe that take a lil trip to probtalk and see some of the cars up there runing on stock internals, now the one kl engine which isn't so boost friendly is the JDM KL-ZE which has a compression ratio of 10:1:1, this engine can hold max boost of 9psi most only boost 5psi to be safe, so in fact the american kl-de found in the probe/mx6/626 are actually pretty good with boost, if you did want the twin turbo set up then you would have to rebuild the engine, i have a link to a 323 runing a kl twin turbo engine doing 760hp!!! thats a beast, one turbo should do enoguh in myopinion and make ample power to shut out many cars

 

my bad about the 114 i meant to put 14psi stock* lol

 

hmmm interesting. i hang out at mx6.com, different sites different opinions.

Moving the battery. there is a duh... opps my bad. A small TT set up i was refering to 2 turbos in series( 3 cly per turbo). and having a turbo above the tranny and next to a fuse box could pose problems.

also 10psi on stock n/a internals is the _safe_ figure. i have seen a stock kl-de go boom whil3 running 12 psi. (i'd say better safe than sorry)

 

yuh i agree, 10 is all you really need, as for the location its pretty much the location the probe and mx6 use for there turbo set up that way the oil can drain str8 down to the oil pan, as for boosting i'm only boosting 5psi on my set up that would be enough for me, i think with my set up i will still be going zoom zoom =-P

 

well best of luck with that. i hope you get proper cooling for the turbo. keep us posted

 

i am gonna have proper cooling, a nice front mount as well
