Blow Through Turbo Or Haltech?

Hi guys, i've done some search about the subject but i still hesitate .. I have a 83 GS with a dellorto and a gsl-se engine + racing beat complete exhaust. I've read a little bit about blow through turbo setups and sounds less expensive, but one of my friend is sure it would cost me less to put a TII motor and a Haltech fuel management instead of going to a carburated setup.

So far i know i need this :

- TII Motor S4
- GSL-SE Oil Pan (already have)
- 13B gsl-se front cover (for oil drain, already have)
- TII tranny with custom driveshaft (is it really needed?)
- Walbro fuel pump or something like that
- I'll have to put the GSL LSD and rear dis brakes
- Downpipe
- Presilencer
- Muffler (Magnaflow)

Should i run with no intercooler ?

If i'm missing some of the parts for the swap.. please let me know.

also, is it possible to run the dellorto 48dhla with a 13B-Turbo?

Thanks

Max

Heres what you really need for a blowthrough:

-turbo prep your carb ($100 maybe? i donno)
-Turbo hat for your carb ($150?)
-Turbo and turbo manifold. ($250?)
-pipe to go from turbo to carb hat ($100 w/ silicone connectors)
-MSD fuel pump (they make only one that i know of)
-Downpipe
-Racing Beat muffler ($275+ shipping, or buy one used)

drill and tap your front cover. Oil line fittings, prolly $20.

So lets see, prolly:
$1500 to get a fullly running complete setup.

You dont need a new tranny or engine block. Yours are fine. You may need an upgraded pressure plate and new clutch, though.

I garantee that going Haltech costs more. Ultimately though it will perform better, get better gas milage, and has greater potential for future upgrades. The downside, besides price, is that it also requires a lot of tuning from someone who knows how and has the equipment. Tuning, if done wrong leads to broken apex seals.

Tuning those this is expen$ive.

I get 17-20 mpg w/ my blowthrough,

the biggest dif between blowthrough and EFI is that EFI can control more boost than blowthrough (i think blowthrough maxes at like 18psi or something, i think i heard that once).

But for blowthrough, you wanna talk to rotary shack.

is it okay to run a 6 port 13B with a turbo ... my engine is stockport, but i heard high compression rotary are not very happy with a turbo, isn't it ?

I currently run like a 4 ports, no sleeves, no actuators ...

you will not accellerate as fast cause you will spin the one wheels as opposed to just going with power going to both wheels

You don't need the GSL rearend or the TII tranny. These are just upgrades (stronger/better). Your car will run fine w/o them.

Unless you have somebody locally that knows Haltech and rotaries, I would go with a carb.

thanks a lot ... this is answering my questions

Ok, so i would run it with no BOV and intercooler?! If i want, in the future, can i put a nice BOV on it ?

Will the motor last long with that kind of setup, and how much boost should i run ?

I think you should still run a BOV. A stock used DSM one is like $20-$40. It'll save your turbo. Anything under 10 lbs is pretty safe (If tuned right). You're motor will last as long as you don't abuse it.

Oh.. yeah that's what i am planning to do, it will be less expensive than buying a ****** jdm motor with low compression and rebuild it and after put it in the car.

But, Paulo, do you know a lot about the SE Turbo swap, do you have MSN messenger so i could talk with you a little bit, my email is mazda_rx793@hotmail.com

high com. turbo setups is the most wonderful thing in the world, 6port se engine runs great with a turbo, as far as the intake goes just do some custom port matching. Why would a want a turbo carb setup, its not the 80's anymore. why would you want to tune you your car daily, and still not have the drivablity, and if you do have drivablity then you are not tuned for a wide open. fuel inj. turbo is the ONLY way to go for daily driven reliabilty.

Ok, which turbo you put on them? I thought about getting a S5 turbo... since they are better than the S4 ones. Do you agree with the others for the MSD fuel pump, exhaust system, i have the dual pipe Racing beat complete exhaust...

Could i put a Turbo II Rear side muffler from Racing Beat, they look good, and sounds nice too.

Paulo,

Share you knowledge. Were you using the Haltech? Where did you put the extra injectors if you had them? I'm currently running a FMU and about to put an AIC on.
