ISIS RB25DET intake manifold

[DeLorean]

I found a site called enjukuracing.com that has a ISIS intake manifold for RB25DETs, essentially it is a knockoff Greddy (Freddy). It seems pretty well priced and from some reviews I have read, the quality is legit. Sorry in advance if I'm posting common knowledge here, also just wondering if any guys here use this manifold in their cars...

As a quick update, I bought one of these from that site, I will let everyone know what the quality is like if they are interested. I'll throw some photos up too...

 

fingers crossed...

I'd be interested in knowing if it's worth the coin. The Greddy one is a nice piece but at $1K plus, not sure if it's worth it.

I bought an ISIS manifold, it was worth it for the price. But there will be a couple things you will want to do;

 

The coolant pipe fitting just kind of slid in to the manifold so I put some black RTV on it and drilled and tapped a hole in the manifold and outlet and bolted the 2 together.

 

Definitely will want to gasket match. The intake ports were quite a bit off in a couple spots. I just marked the manifold with the gasket on there, with a sharpie. then ground the aluminum casting with a dremel tool until it lined up.

 

DON'T use the fittings they send in the kit! I had 2 snap off, in the manfiold. I would go the the hardware store and get a 1/4" NPT tap and all new brass fittings.

 

All of those things took about 3 hours maybe. For sure worth the 500+$ you will save. I am happy with mine, for the price. We would all have Greddy if it wasn't for the price...
