Does anyone know where to find a ga16de turbo manifold or a custom one i have a ga16i and a t3 turbo off a saab and i was thinking of welding a t3 flange to the stock exhaust manifold but was wondering if anyone knew where to get a turbo manifold i have searched the web for hours (literally!) and with no luck so if there is a company that sells these it would really help me out allot! and if anyone has a turboed ga16i some tips or pics would be nice thanks! :confused:

thanks man but to expensive ill probably end up welding the t3 flange to the exhaust manifold and i was also wondering if there is a way to program or change the air to fuel ratio to compensate for the boost if any knowledge that would help

yeah im pretty aware of my situation i've seen it done so i just needed some help i've removed the cat put 2.25 piping to a magnaflow muffler ported and polished the head cold air intake and advanced the timing with the cat off it runs richer (less back pressure) i also took the egr off so i think my air/fuel ratio is good for 5psi its ghetto but i cant afford $800 ems systems thats rediculous im just looking for a good performing car i dont think im going to be drag racing it i just want it to be a good street car on a really cheap budget.

I gotta say, if you don't have the $800 associated with a standalone fuel programmer, i don't think your turbo idea is going to work... You can't just expect the engine to accommodate all that extra air just by making it run rich. The a/f ratio has to be able to quickly change to meet the demands of having huge, dynamic amounts of air being pushed in from an outside source. Have you considered a wastegate or turbo timer as well? And you have to run oil lines to your turbo.
I think "Beyond Biscuits" has a turbo setup on a GA16i. I would ask him about it.

he has a GA16DET...

no one has a turbo'd GA16i right now. supposedly a guy in mexico, but i kinda have a feeling its a GA15E, because i believe you can get em in mexico.

as for the standalone, you would have to.

Mervic turboed his 16i, but then removed it because the TBI fuel system is so inadequate for it. if the 16i was a dual point TBI system, then you could go with 2 massive bottom feed injectors for mild boost. the main problem with the 16i is the single injector, and thats it really.

i would strongly advise against trying to turbo it. period

Ah, i had only seen one of his Youtube vids a while ago, and i didn't catch the GA16DET part. Didn't know they made those. Is that a GA16DE he turbo'd?

Yeah I went through all in the ins and outs of turboing an e16i with my brother, a professional technician who has turbo'd many nissans and he said simply: Do not do it. Swap a ga16de its way easier, and you can find those engines for 300$ sometimes less. I just bought a full running, nice looking 94 sentra for 400$ for the swap. Think aboot it.

yeah i have a saab turbo with internal wastegate rated at 7psi i was going to use a boost controller to only run about 5psi and i know that a stand alone is important but i dont have the money for one so maybe bumping up the fuel pressure with a aftermarket pump would help and well i was hoping that the air flow meter on the throttle bodie would compensate for the boost a little and i dont think that i will mess with the timing because the engines already have pretty low compression. and yess i know the turbo is cooled and lubricated from the oil i have already bought oil lines for the project and a oil cooler. i dont want to do an engine swap because the motor was recently rebuilt. i have already had the head and intake ported and if turbocharging it doesnt work i will probably mill the head down for increased compression, im just looking for was to increase the power of it because im kind of stuck with the car for awhile and if it was my choice id rather have a 5.0 mustang than these wimpy 4cyls.

well i found the solution to my problem apexi makes a fuel controller called a safc2 thats works with turbochargers and adjusts a/f ratios this just might work check it out.

Apex-i S-AFC II Fuel Controller
Dude I'm telling you right now that is NOT the way to go. Unless you have a wide band O2 setup to tune that SAFC it will be full of fail. The ECUs on these old nissans are inadequate for compensating for that SAFC. You see it is hardwired to the ECU and modifies the input to "trick" the engine into thinking that the mixture is lean, thus increasing the AFR.

These statements come from personal experience of putting an Apexi AFC on a D16Y8 engine with a "home built" turbo setup liek the one that you are bent on building. It failed. Drove it fine, for a whole day. Trashed my engine and I lost about 6K selling what was left of that car..
