ok guys im some wats new too turbo im lookin too see wats the diffents from a top an bottom mount manifold, most people use bottom but i like the eqaul lenght with the dual wastegate, Soo if anyone can shine soem light on this for me an its going into my 91 civic si soo my worry is which on will clear with my 97 gsr 9:1 piston rods an for power im lookin too make 450 with a gt 3071r tubo

 

Top mount looks cooler and cost more.... pretty much about it.

 

Yeah, fitment in that chassis is tight, but it certainly can and has been done. A topmount is gonna create some lagginess though that you can avoid by going with something more "compact", while still easily meeting your goals.

 

This has been covered many times...

It all really depends on ur taste and budget!!!
There are lots of company that makes decent manifolds so there ya go....Good Luck!!

do a search, lol Me and Tony1 argued about this before.

And Full-Race did a manifold test with a Log, Ramhorn & Topmount on the dyno. If you give them a call they will enlighten you more so than some1 is willing to give you the time for a proper reply.

If i was on my main computer Id just copy and post the gains, but somtimes its better to keep it simple. If your going ALL OUT and need that extra 30-40 hp on a 600+ whp setup, Go Topmount. If you have money to waste and want to spend extra for a Topmount on a 300hp car, Go for it. Only you can make the choice,

 

In that chassis i'd go w/ a bottom mount, foror fitment/clearance reasons and because a topmount is not necessary for that power level.

 

My SLS top mount spools my .82 76R way quick!! faster than my old bottom mount setup with a .63ar!!

 

Both are great manifolds, But Id have to go with PSI2HI and go with a bottom mount.

Its better suited for the goals at hand.
