goldenvtr Posted November 2, 2016 Share Posted November 2, 2016 (edited) 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 as im spending money on trackdays in my mx5 next year and this is quick enough for now just had the wheel refurbed and 4 new conti contact 6's brilliant tyre, very close to how my mx5 feels on pilot sport 3s Edited November 2, 2016 by goldenvtr (see edit history) Quote Link to comment Share on other sites More sharing options...
steve spedd Posted November 2, 2016 Share Posted November 2, 2016 Pretty good figures got there. Well done! Not sure how long the W58 will last!! Nice to see another NA-t getting good results Quote Link to comment Share on other sites More sharing options...
goldenvtr Posted November 2, 2016 Author Share Posted November 2, 2016 (edited) 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 Edited November 3, 2016 by goldenvtr (see edit history) Quote Link to comment Share on other sites More sharing options...
Style Posted November 4, 2016 Share Posted November 4, 2016 Pretty nice results there, well done I'd get some injectors on your list too as they'll be running full tilt soon. Better to have a set running at a comfy 80% or so Quote Link to comment Share on other sites More sharing options...
