So to follow on from my old thread:http://www.mkivsupra.net/vbb/showthread.php?327097-my-DIY-Na-t-w58-7psi-344bhp-amp-298-ibft

 

ive just got back from dynodaze with a fairly good result

 

basic spec is now:

2jz na-t with tt cam covers

w58

hx35 7blade 12cm

arp headstuds and 1.8mm tomie head gasket (0.2mm skimmed off head)

vvti coils

sard analyse ecu with safc2 (road tuned by myself)

tomie fuel pressure regulator

440cc rx8 injectors at 4.1bar (should be good for about 470bhp)

blitz boost controller

50mm waste gate recirculated

3" turbo back exhuast

 

 

 

 

 

1.2bar made: 438bhp and 388ibft but with a misfire - they suggested spark blowout, see graph

1bar made 405bhp and 361ibft with no missfire and smooth curve

"

next step is spark amplifier and smaller plug gap, 4" exhaust just for the sound as its quite tame at the moment then prob 2018 look at a gearbox swap and max the turbo out :D as im spending money on trackdays in my mx5 next year and this is quick enough for now

cheers it drives great on the road 1.2bar by 3300 in 4th & i've been running like this for about 6/7months, so far so good, i'm pretty conservative with gear changes as i know the w58s suck and im not ready for a box swap just yet but it will happen eventually then i can go mad on it :D
