this its kinda stupid......
i am doing my little research for building my own home made turbo.......
i almost got my turbo choosen....... anyways i got a D16Z6 on my STD 90 HB...... i was looking at info and in a few places i keep seeing that i need an CRX HF manifold......... what that means ... i have seen into the CRX HF and their exhaust manifolds dont look nuttin like the ones used for turbos.... i want to know wich car really carries that good manifold that i can use for my home made turbo.........
also if anyone has done this on a Z6 and has a part list, comments, or info that can help me on this proyect i will really appreciate it!.......peace!

yes indeed the HF mani will work as it has the catalitic converter bolted to it directly, and that's where you'd put your turbo, with a help of an adapter. as a matter of fact your old STD mani would do as well. take a closer look at it...

If you need the HF manifold let me know. I have one in my garage, don't need it anymore. Going for a b16.

I can get you an adapter plate made for you to fit perfectly with a Garret T-3 to work with an HF mani. Comes with all bolts, and gaskets. Smokinsax@aol.com

How much do the adapter plates run?

i got an old STD manifold here from my old STD
that means i can cut thart **** and half and weld an adapter...??
sweeet
thanxs guys!

Ash J. Williams

if your mani looks like this
you are go.
there is no need to cut anything, just unbolt the cat and use an adapter, welding cast iron is unadvisable.
good luck

that's a DX or an SI mani, prolly someone replaced it. get an HF or STD one, don't pay more that 25-30$.
good luck

Ya.. I'm starting to do my own turbo project a' la homemadeturbo.com.

I got my custom adapter plate made for $90.. 2 hours of labor, no parts.

You can check out my adapter plate and manifold on http://www.driftkids.com

my std. manifold looks like that. It does not have the cat bolted to it. the cat is under the car.

USDM 4G VTEC

thats not an Si or DX manifold
that its a 90 STD manifold.... car was completely stock when i bought it,...... all STD i have seen are like that!
but still i rather have da HF than the STD with an adapter welded... the turbo will be too low...

Mugen Dom

u are wrong teh 88 std had the cat at the motor i own a 88 std and a 90 std the 90 looks like urs teh 88 is similar to teh HF but larger ports

RedRacerCivic

i have 92 civic CX manifold for my homemade turbo...

Mugen Dom

the vx also has a similar manifold

89 CRX SI

ok ill let you in on some info the DX or Si manifold can be used but rad clearence gets to be a problem.

here is my setup. forget adapter plates just weld the turbo to the manifold and cover it all with heait sheilds.,

Mugen Dom

and then when u need to change turbos u can do it again an adapter plate is much easier to do and safer dont gottaw orry about the welds breaking

89 CRX SI

the welds wont break cause it was done right with a mig welder cranked up. if i ever want a new turbo i sure the hell wont be using that POS homemade amnifold. It sort of just gets the preoject rolling.

Mugen Dom

and then ull get to make a new downpipe also cause it wont be situated in the same spot

89 CRX SI

hehehe dont remind me of that. what ever it was free cheap and fun.

rjardy

i cant believe that you welded two peices of cast iron together with a mig welder..............

not my cup of tea, but hell, if it works then good on you
