thats the main reason i bought it. im sure the runners are slightly larger in the jam mani. might just be my memory isnt too good as i cant really remember, have a stock mani somewhere

I'd agree that these are a step up from the stock unit. JAM have obviously considered reliability over the performance aspects.

The standard manifold can last up to and beyond 15 years. Would be interesting to see the lifespan of these in comparsion if bolted to a standard 4EFTE.

Nice purchase Duncan, keep us posted on how it performs.

well im off to toyota tomorrow, if i have time, to order the gaskets. used the current ones twice now so dont wanna risk a third time as ill be pissed off if they leak!
when i recieve them ill get cracking fitting everything and see how it all goes. may change my turbo to my other ct9 too so may not be a very good comparison but hey!
