SOLD! 1973-ish Datsun 240Z with V8 from 1997 Trans Am
kenny_b posted a topic in Cars for SaleI am selling my 1973 Datsun 240Z. Bought as roller without engine/trans in 2011/2012. Previous owner/s have changed the roof and various parts, so some of the stuff i pulled out was off a 260z/ 280z and there might still be some mixed parts on it. That and all the modifications pretty much eliminate this as a show car. Do not buy this thinking it can be restored to show car quality. It would take far more than would make economic sense. This is purely made to run quick/fast, not to look pretty. It's raw and needs muscle to be driven. It has manual brakes without booster and manual steering without power assistance. You need to be strong like bull. But it is rewarding! If you dare you can get 0-60 in just over 4 seconds, while carrying a passenger. I've never felt the need to put effort into it, but I am certain it'll crack the 4 second mark if you just lower the tire pressure... This is a great handling, light weight car with balls! Once you get used to its noise and raw roughness or like me, fall in love with it, this car is AWESOME! Took it to tracks and autocross events and thoroughly enjoyed the @#$% out of it every time i drove it, but I am almost done building me next racecar and I need the funds to focus and finish it up... Now to the great things about this car. I'm just going to list as much as I can and I'll save some details for when you come to see it: SOLID 1997 Pontiac Trans Am LT1 V8 with 310 hp at around 5250 rpm and a torque curve that starts well above 320 ft. lbs. from the word go all the way into the rev limiter. Max torque 340 ft. lbs. Stand-alone engine harness and Howell Engineering computer, tune-able, obviously T56 manual 6-speed transmission out of the same 1997 Pontiac Trans Am S1 Sequential Shifter that translates forward/ backward motion into the H-pattern - yeah, it's awesome! R200 rear diff with a fantastic Quaife ATB torque biased helical limited slip differential upgrade and 3.545 final drive ratio Nissan Armada CV jointed half shafts LED sealed beam replacement headlights with aero covers Both, front and back bumpers lightened (not good for crash resistance, so be aware) Fiberglass bumper covers, front and back, front with lower air dam Fiberglass fenders Fiberglass hood with vents and secured by lockable aerocatch latches Fiberglass cowl Fiberglass flares Wilwood brakes (almost 13" all around) with 6 piston front calipers and 4 piston rears - high temp fluid, track disks, track pads, biasing valve installed Complete Arizona Z car suspension kit with billet control arms etc pp, which keeps the rear control arms straight while the vehicle is lowered! 5-lug Rota wheels 17x9 front and 17x9.5 rear with Nitto NT01s in 255/40/17 fronts and 275/40/17 rears Autopower bolt in 10 point roll cage NRG hub and deep dish steering wheel with quick disconnect and lockable cover Custom light weight polycarbonate dash board Dakota Digital gauge cluster with 0-60 timer and 1/4 mile timer and couple neat functions Ignition activated dash cam with GPS Corbeau racing seats on sliders, forth and back adjustable!

My MS3/MS3X full sequential spark/fuel settings
Chris83zxt posted a topic in MegaSquirtSo it took me one afternoon to rip out the stock injection and get the car wired up and started on ms, it's taken me almost three months since to get things to where I'm pretty happy (one month delay thanks to the stock T3 blowing to bits). My car: 83 l28et, p90a head, stock block with at least 206k miles. Last time I tested I had low compression on #6 (110 vs. 145 on rest). My compression tester was stolen along with my truck and I haven't replaced it yet. I think I might have blown the ring back into place while letting VEAL tune the upper regions of my ve table whilst doing 3,500-5,000 rpm on the interstate in 3rd for about 20 minutes last week. It's run silky smooth since that session after the lifters quieted down (I was worried that I had done something bad until I learned that was common with hydraulic lifter setups). The non-stock stuff is: 3" K&N filter in the wheel well under the drivers side headlight, 3" piping up to turbo. same-side ebay fmic ebay type-s bov recirculated via a 1 and 3/8 line back into the intake just before the turbo. EGR is deleted and blocked off. I have had the intake and exhaust manifolds mildly ported by Lonewolf Performance. They also welded a 1/2" T3 spacer onto the exhaust manifold and a 38mm tial wastegate flange as well. I am very happy with their work. 60mm 240sx TB and TPS EM USA external wastegate set to between 15 and 18psi depending on the gear. Holset HY35 (used, fair condition) New, bigger downpipe for Holset with first O2 bung located about 1' downstream of the turbo--catback still whatever came on the car cause it's in good shape and I like the sound characteristics Ebay injectors which are supposed to be high impedance custom versions of the Bosch 403 injectors (~550cc) - so far they seem to be the real deal Palnet 14mm fuel rail Walbro 255 GM flex fuel sensor (the newer one) D585 LS truck coils (round w/ heatsink style) A set of Silverado shorty plug wires A Bosch 505 idle valve (3 wire) A homemade tach adapter Innovate MTX-L wideband and gauge Speedhut electronic fuel pressure gauge Some ebay boost gauge retrofitted in place of the stock boost gauge which is semi-accurate GM open element IAT sensor (between IC and TB) (using the CHTS as the coolant sensor for MS) DIYautotune dizzy trigger wheel DIYautotune supplied MS3/MS3X 3.57 with integrated knock sensor circuit DIYautotune MS3 and MS3X harnesses (recommended -- not a single sync problem since the first startup). I think that's most everything that's relevant to the tune. I've found the flex fuel sensor is working pretty good in tandem with MS3 and I'm able to switch to different blend ratios without it throwing the ve map off. My cold start settings are based on testing with approximately a 60% ethanol blend. There's a decent chance that at the colder temperatures they may foul plugs with pump gas. It started on the third try a little while ago with the block at 13 degrees so I'm pretty satisfied with the settings as they are (tomorrow morning at -10 should be interesting). I'll probably dyno it soon. You can see by my upper VE map that the porting work and bigger intake tract has shifted the peak torque region closer to 4,700rpm, if you've got a bone stock setup you might shift the fat area of the ve table a few hundred rpm to the left. Here are the settings I'm using. I hope these are useful for someone, lord knows I've gotten a lot farther a lot faster than I ever could have without the knowledge on this site and others.
