HO exhaust manifold on a Renix

Recommended Posts

I am trying to figure out if a HO exhaust manifold will fit on a Renix head. I understand that it will not have a bung for the EGR or the O2 sensor. The O2 sensor will mount in the new HO down pipe. I understand a bung would have to be added for the EGR. I am trying to figure this out because I need a new exhaust and a new manifold. The HO manifolds are cheap and have the bellows. The renix manifolds are about $100 more. I am going to replace the down pipe either way so if the HO manifold works it's just cheaper. I am also going to add in an extra piece of flex pipe when I do the exhaust. Wondering if anyone had actually done this?

The exhaust ports are different. Don’t waste your time

Not true at all. Bolts right up.

 

HO exhaust manifold on Renix

As far as exhaust, you can use the Renix exhaust manifold and be fine.
If you want to use the HO exhaust manifold, you must go with an HO headpipe and screw your O2 sensor into that headpipe. Standard Renix harness is plenty long to do so.
A bung can be welded into the HO manifold to accept the EGR tube also.

If anyone ever comes back to this the answer is yes. You need a HO head pipe and round the corner in the intake.

Use the renix gasket so the intake lines up. The exhaust ports are identical.

They sure look different.

HO head pipe for the O2 sensor bung and different drop location. You will have to deal with the EGR pipe.

I just deleted the EGR.

Round both bottom corners.

Just a little.

Is that plug this part? Been looking for a plug the size of the EGR port under the intake..

New head pipe installed.

The O2 sensor wiring fits perfect. And the sensor is easier to reach.
