Intake Manifolds where is the list? THe goods the bads?

Shopping around for a intake manifold

Greddy rolls $900-$1000 shipped i was wondering of other options?

Ive heard alot of TopHat also

Who are the good companies that make these or is it Greddy or Tophat only?

I am thinking the $200-$500 on eBay might not be so well made

Yeah forget the ebay ones.

The castings are very rough and porous. A lot of them have air leaks and/or coolant leaks. I have seen them leak coolant into the inlet runners.

Why do you need one?Hood clearance, or shorter intercooler piping or something?

I didnt really plan on getting one but reading the rb20 dyno thread that is going on right now in this forum got me insterested, i havent even dropped the motor in yet so i dont know if there is clearance issues

(rb25det into s13)

All of the short runner manifolds will lose you midrange, thats a fact.

That Top-Hat one looks good because it keeps the long runners but gives a better path for the intercooler piping.

However the standard inlet manifolds don't become restrictive until over 400hp, that is also fact.

so the money is better spent on something else... thanks TSL
