RGTorque Posted April 30, 2009 Share Posted April 30, 2009 hello all, im going through some changes with my 7 and i thought id make a build thread (with some coaxing from kevin). http://usa7s.com/vb/picture.php?albumid=6&pictureid=22 this situation has come from my desire to quiet the exhaust and get myself some more power on the street. the major problem is that my current exhaust runs down the center of the car and in certain areas has been crushed in order fit around the frame and by trans. the only thing quieting down this system is a set of glass packs that are... subpar.

RGTorque Posted April 30, 2009 Author Share Posted April 30, 2009 so far the plan is as follows. ~gt28r turbo ~intercooler from kevins car (thanks!) http://usa7s.com/vb/picture.php?albumid=6&pictureid=29 ~turbo header made from stainless steel ~nascar style oval exhaust pipe to slip by the trans and frame ~possibly 2 vibrant resonators to take care of any high/low notes left in the system. power potential ~160-185 rwh with stock miata clutch ~200 rwh with upgraded clutch ~230-250 rwh with upgraded 550 injectors ~300+ rwh w/ pistons, rods, headwork ~XXX rwh bigger turbo and the above. right now im just looking for low boost to make sure all things will run smooth. im not planning on using the turbo much on the track but i would like some boost for the open road.

scannon Posted April 30, 2009 Share Posted April 30, 2009 What engine and ECU are you using? I looked in the member's rides section but didn't find your car. Link to comment Share on other sites More sharing options...
RGTorque Posted April 30, 2009 Author Share Posted April 30, 2009 the motor is a 2001 miata vvt motor and the ecu is hydra 2.5 Link to comment Share on other sites More sharing options...
slngsht Posted May 1, 2009 Share Posted May 1, 2009 I love your solutions... "My exhaust is too loud, so I'm gonna buy a turbo" LOL Mine was too quiet, so I did heads, cam, and long tube headers. Link to comment Share on other sites More sharing options...
RGTorque Posted May 1, 2009 Author Share Posted May 1, 2009 truth be told ive wanted to redo my exhaust since i purchased the car. this way i roll a part of the cost into some upgrades. Link to comment Share on other sites More sharing options...
shiva Posted May 1, 2009 Share Posted May 1, 2009 If the engine is a miata I would look hard at the Mazdaspeed manifold and turbo if I were you. It's a great setup for some more HP and the way the manifold is setup, it would probably fit easily. Flyinmiata westfield's run with one of those.

TheDingo8MyBaby Posted May 1, 2009 Share Posted May 1, 2009 Agreed with shiva. Try to stay away from those cheap stainless ones from china. They're no good. Link to comment Share on other sites More sharing options...
scannon Posted May 1, 2009 Share Posted May 1, 2009 the motor is a 2001 miata vvt motor and the ecu is hydra 2.5 I think your HP estimates may be a little conservative. My Caterham has an '00 Miata motor with VICS. With 550cc injectors and a Hydra 2.6 it pulled 301 RWHP and 265 lb ft at 12psi. The engine is otherwise completely stock. The Mazdaspeed manifold and turbo does fit tight against the block but they are limited in flow relative to the aftermarket manifolds & turbos. I used an FM manifold and the Garrett 2560 ball bearing turbo. My exhaust is still on the loud side. It is 3" with a metal cat converter and glasspack muffler. It splits into two 2" factory Caterham tailpipes to get clearance as it goes under the car for a rear exit. For track work I have a side exhaust with no muffler or cat. That gets really loud, ear plugs and helmet help but my ears are ringing after a day on the track. I am using the clutch from a Mazdaspeed Miata with an 8.5 lb steel ACT flywheel. No problems with slippage so far (and it has been tested many times ). Link to comment Share on other sites More sharing options...
RGTorque Posted May 1, 2009 Author Share Posted May 1, 2009 thanks for the advice guys. i looked into the mazdaspeed mani/turbo but for the price $1200 from flyin miata i think i can do much better for a little bit more $. if you look at pic 6 + 7 you will notice a support beam right on the exhaust manifold. the worry is that while the turbo hangs low it will still be right up against that part of the car. i dont want to risk that much heat or have to deal with a an install in such a small space. i picked up a good used gt28r for $300, getting a custom stainless manifold made for $500-700 est, and have all the flanges i need for an additional $80. the turbo will handle more then then the mazdaspeed setup and i have the benefit of moving the to a much better location for cooling, ic piping and ease of install and removal Link to comment Share on other sites More sharing options...
