just a few pics of my 99% finished 400+ whp project na mx5(german sold cars were called mx5 in 92 )
started out as a modified greddy kit a few years ago..
diy ic pipes, link , 440cc, all the normal bits.. running 15psi boost. Soon got tired of having just beeing a little slower that the regular porsches etc on trackday events. upgrades had to be done..
Tossed the 1.6 engine. put in a 1.8 from a protege, did not have a inlet manifold for a miata, so i buildt a quick and dirty diy one.
engine had carrillo rods, wiseco pistons, a t3/4 turbo, tial 38mm wg etc..
was running 22-23psi boost.. suddenly the porsches was not a problem.. would easily slide past a 996 gt3 on the back straight.. annoyed the hell out of the porsche guys, lotuses etc..
engine had a coolant reroute 750cc injectors etc too.. but the workmanship on the header was not good, and the quality of the materials were not good either.. also had issues with heatsoak of brake components in the enginebay..
time to redo everything
build a better header downpipe combo, for the gt3076 turbo.modified a enthuza 3" system with vband etc.
redid the coolant reroute a bit. better heat shields, rerouted brake lines.6 speed tranny, 3.6 torsen, afco's +++
Engine internals are still the same, balancing of the engine is better, the head fully ported, and running maruha cams.
Engine mangement changed to a autronic sm4 1.09 and chevy ls2 coil setup.
Ran the engine like this a bit last year.. testing things out.. works GREAT.
then some Inlet manifold changes.. redid the entire thing.
billet runners for the new manifold. watercut flange
dual chamber design (sort of like the old grB cars. we have been using this design with great success on 520whp race/rallycross spec saab engines, cosworth engines etc) and running a 70mm tb.
ready for the trackdays... almost :P
some finishing touches left a lot of places on the car.. but it almost there..
thanks to fm by the way, for great support on the afco setup..
Keith, i got all my parts installed, hoping to drive the car in a few days now.. will let you know how the 650/400 setup works :P
the speclist of this car has spiraled out of control the last few years, and i cannot really keep track of what has been done.. but i think the dash is one of few parts not touched.
First trackday test was in july..
sportscar club of norway had a trackday today.. lots of great cars.
Lotus exiges, porsche GT2, radical, 4rotor rx7. ++++
the car is a monster.. .65 bar boost. 3rd gear powerslides uphill on r888 tires, and set a laptime of 1min7 seconds. my friends GT2 with some ruf tuning(550hp, 780nm) did a 1.05something using r comps, racing suspension etc.
cant wait to get it properly tuned.. im expecting it to keep up with the modified GT2.
My dad was a very quiet passenger for the last set of laps for the day.. while i was chasing my friends 4 rotor rx7
lovin the black 15x9 6ul rims with r888 tires
my first attempt at some decent looking shots of the car in its current spec.
also. a clear shot of the engine in current spec all heat shields etc in place...
also.. a very small clip of a testdrive near my garage..
YouTube - first test
Kind of a massive first post in the build theads.. but hey.. its almost finished now
Hope you guys like what you see.
dyno time VERY soon. hoping for 400+
