No particular order:

1) Local U-pull or already pulled junkyard EX exhaust manifold years 96-00.
2) Ebay used
3) Craigslist used parts
4) Can replace with headers but, won't help gain power.
5) This site: http://www.car-part.com/

so is there any way to makes this particular model stronger, any type of turbo that can be adapted or something?

You need an actual turbo manifold to slap a turbo on. Any old exhaust mani/head won't do the trick, that is, unless you have it modified with a turbo flange on the outlet. Even then, you're gonna have to modify the downpipe to accommodate for the extra length the turbo adds. If you wanna go boost, your best bet is an actual turbo manifold.

edit: for visual reference the following picture is a turbo manifold designed for a D15/D16 engine

Note how the turbo flange sits quite high compared to a standard outlet of an OEM exhaust manifold. Not to mention, (this tidbit of information I was not privvy to until just now), the OEM exhaust manifold of a D16Y8 is a 4-2-1 design.

Also worth noting, the picture I linked has a turbo manifold that is of a "ram horn" design, where the exhaust runners have been extruded to wrap upwards, allowing for equal flow from the cylinder head exhaust ports to the turbo inlet, allowing for steady flow to rotate the turbo's CHRA

then thats it, thanks for that reply, i would try that then

A couple of things to consider when shopping for turbo manifolds..

1) the turbo you're using. The turbocharger you choose will have different inlet flange sizes. The turbo manifold you buy needs to have a flange that'll mate up with that inlet flange

2) more on the turbo you're using. Is it internally wastegated or externally wastegated? If it's the latter, your manifold needs to have a port for an external wastegate, like this one:


3) how you want the turbo to sit. There's not very much room to work with when boosting a D-series. You'll need to make sure the manifold holds the turbo in an orientation that allows you to not only physically fit the turbo in the engine bay, but also in the correct orientation to allow for your plumbing to mate up properly. Often times, that's also accomplished by the turbo exhaust outlet piping. When I was boosted, the turbo exhaust outlet was designed in such a manner to mate up to my existing downpipe. Since my D17A2 has a 4-1 exhaust mani design and the D16Y8 has a 4-2-1 exhaust manifold design, you'll have more room to play with.
Also, slim radiator/AC fans help with making space. I can personally recommend this fan. I replaced my radiator/AC fans with these since they're cheap and I needed the room for boost. These have a profile of about 1.5" deep, vs. the OEM fan shroud that sticks out from the radiator about 3-4 inches. Also, the flowrate is better than stock, so win-win. I've long since removed my turbo, but these fans are still going strong. I had to get creative with mounting these, however, since the traditional "through-radiator" mount is crap for longevity.


If you have any more questions, feel free to ask. I have a bit of experience in the boosting a D-series field.

OP..sounds like you're wanting to boost. Do you have any idea of what all that entails? Do your research first..plenty of info online.

Tansmission manual or automatic?

so i have to take off the crappy stock radiator to fit an aftermarket one i order to have space for my manifold and the turbo?

and also what ma ifold yohre using? and which turbo?
