Ok guys, I bought what I thought was an HF manifold, but under closer inspection it seems to not be an HF after all. It is very similair, but there are some notable differences. Here are the pictures:





Now the question is would it be ok to use this manifold, and which manifold is it? Or would I be better off looking for a regular HF? The runners look very thin to me, but I have no clue what size the HF ones are. So that's my main concern, the flow capability.

Thanks.

 

cant say ive ever seen this before

 

look like a manifold from D16Y7, cat chopped and adapter plate welded.

 

EK is right on this, it's commonly referred to as a CX manifold. It will work for turbocharging, but will probably place the turbo so low, that attaching an oil drain properly will be difficult.

Design wise would you say this is worse then the HF, the same, or better? Because if its the same or better I may try and use it, but if its a worse design that will only increase lag and restrict flow, then I'm gonna get something else.

I also did some estimated measurments of where I believe an HF manifold WOULD end, and it seems that this one is only about 5cm longer. Is that enough to create the problems with the oil draining?

Thanks for such prompt and helpful replies.

 

It will work fine and the oil drain will be ok. Looks like a T3 flange welded.

 

Same here, but I've also seen some of them run into problems with the oil drain.
