To my knowledge what gives more power(those 59hp..) on the racing beat turbo back full system is the 3" downpipe, right? so, since I can't get racing beat stuff easylly, is there any substitutes that do the same, or can I ask somewhere for them to do the downpipe?
one more thing: if it's the downpipe that gives that power, getting a even more free exhaust will give even more power (less restriction) ?
and also, that Fuel Cut Controller.. what do they do exactlly? can I get them from someone else other than RB ?

thx in advance

yes, the removal of the cats will help you boost more and make more power.
A 3" exhaust should do the job nicely.
The FCD will trick the ECU into thinking that your boosting lower than you really are, so the it doesn't fuel cut. There's other manufacturers that sell em too.
Now if you get a free flow exhaust tho, be sure to get some fuel mods also, you don't want to be running too lean and pop your engine!

so what increases the boost on the racing beat system, is the removal of pre and main cat ? nothing to do with the rest of the exhaust system?.. and will get those 59hp (on the engine) or more with another 3" system. right ? damn I can't wait to get that car !!
thx for the help
(yeah I still don't have the car.. I want to know better what Im about to buy... :P )

With the removal of the pre and main cat, you have less backpressure on the turbo, thus allowing the turbine to spin faster, thus creating more boost on the compressor side.

any good 3" system will help you gain HP. Just make sure its good quality.

A custom made exhaust with no particular engineering will net you some serious gains. Check out what I made with stock boost on a 2.5" exhaust: http://www.geocities.com/jeffguilfoil/dynoresults.html

If you dont mind noise you could put a single exhaust in = less weight

The next problem your going to have is boost creep. When you take the old DP off it would be a good time to port the wastegate. Other thing that go with your project

Air pump removal (dual alternator pully or Yahoo belt), ACV and split air pipe removal (ACV block off plate), FCD or better yet get a Ritek 1.5 and a boost gauge

Yes you will increase the flow and decrease the back pressure on the turbo which will make you hit 12 psi of boost. Works great for a little while till you blow a Apex seal. Thats why you need to port the wastegate. Trust me I've done it.

Been out of home for a while, haven't checked this out till now!! and I have to say Im something like this right now !! very nice to see ppl helping me out here!! Im used to get my *** kicked.. lol
thx!! this was some valuable info !!!
one question, only one pipe doesn't equal to more resistance? unless its larger than eachone of the other two, but it had to be the double.. :P
damn, I just can't wait to get my hands on that car!!!!
thx again

Shiver - Stock, 2nd gen Rx-7s did not come with a true dual exhaust. It's a Y exhaust that splits off a Y pipe, shortly after the two seats..

so when i get the 3'' downpipe from rb i should port the wastegate ive never ported one before how hard is it would it be easier to just send it somewhere to get ported is there anywhere that would do that

lol...
I knew that.. I guess that was a stupid question I made!! :P
Thx for all the help. that site that dr.jones63 gave me rocks !!! (still have to see if they ship to europe..)
