justin240 Posted November 20, 2014 Report Share Posted November 20, 2014 (edited) alright so just to start off, i finally bought a second starion, i had one a few years ago, bought it, put a clutch in it the next weekend, and then lost my job the weekend after that and had to sell it (been sad about it ever since) so after a few years i finally stumbled back asswards into a second one, this one is an 87 last one was a 86 both widebodys (love the look) so just to start with the list i have recieved on this particular car as told from the previous owner, my research has proved most of it to be true1. bored out to a 2.8 with weisco pistons2. non jetvalve head3.bigger injectors4.motor, ecu, and wiring out of a 89 (better fuel mapping?)5. freshly rebuilt turbo with a full straighpipe (turbo elbow, bend to follow under the car, straight out the back, sounds like a damn diesel..... i like it)6. i was told it was dynoed at 372 wheel horsepower at 20 psi, unverified but it seems like it might make that much, boost is currently turned down the the clutch is well on its way out, a new one is coming in 2 days then we shall find out for sure problems i am having with this particular car1. super super rich, i assume its due to running 8 psi with bigger injectors, it pulls hard, one little hickup at around 4.5k then it pulls hard again to 5k before hitting what feels like an ignition cut, super loud backfires and flames, sounds like 2 step launch control but otherwise doesnt effect the daily driving of the car at all2. i have a few broken vacuum ports right off of the upper water neck that i dont know what they are so i cant replace them till i find out (will post pictures) things i would like to this carso like i said i have a clutch on the way, i also have a wideband on the way and a few other gauges, acurate water temp, oil temp, oil pressure1. i went to a junkyard today and managed to find a narrow body 84, it had a digital gauge cluster in it, i would like to swap my analog one for the digital one, i have searched but only found results for the technica? cluster, i havent found anything for the early model digital clusters, my fuel gauge doesnt work so i would like to swap the clusters if its possible, i have built plug and play harnesses for the nx digital cluster into 240sx's so wiring is easy for me i just need to know if anyone has actually done it and if its actually possible2. has anyone made or found brackets to mount a single din radio into the stock location? i managed to wedge mine in but i would like to clean it up and have it actually mount properly3. the same car i pulled the cluster from has rear window louvers, they are mounted on the top but they dont have the bottom latches, where can i find some and do the narrow body louvers fit a widebody car?4. my car has no floor mats (typical) the 84 at the junkyard has perfect condition red floor mats( matches my perfectly clean interior) are the mats that say mitsubishi on them oem original floor mats or are the oem original ones only the ones that say starion or conquest?

justin240 Posted November 20, 2014 Author Report Share Posted November 20, 2014 apparently the picture of the broken sensor i have is to big to upload, anyways its right behind the distributor on the water neck below the thermostat, its got 2 vacuum ports on it both facing up, the farthest on out is broken off and i dont know what the sensor is so i cant ask the guys at a parts store Quote Link to comment Share on other sites More sharing options...
TexasQuest Posted November 20, 2014 Report Share Posted November 20, 2014 First off, welcome to the site. Highly doubt it's making 372 whp if it's still tbi but hey anything is possible. Super rich under boost is normal and requires a tune (MAF Translator, SAFC, etc.) There are write ups for a digital cluster conversion. Louvers fit from any year, any body type. Mounting clips are very hard to find for them. OEM floormats say either Starion or Conquest. The broken vacuum port you found is the thermo valve. It's an emission component to put vapors back in the intake manifold to get burned off. Quote Link to comment Share on other sites More sharing options...
justin240 Posted November 20, 2014 Author Report Share Posted November 20, 2014 (edited) i dont believe its making 372 either lol but like you said anything is possible, it certainly has work done to it i will find out exactly how much and exactly how much power very soon, any ideas about the 5k rev limiter? or the soft cut limiter? are these stock ignition cut or stock fuel cut? and is the thermo valve required? i have no egr, i want to delete alot of the vacuum lines but the diagrams on here are very confusing Edited November 20, 2014 by justin240 Quote Link to comment Share on other sites More sharing options...
TexasQuest Posted November 20, 2014 Report Share Posted November 20, 2014 Thermo valve is not required. These cars don't have boost cut per say. The maf signal gets scrambled when you reach a certain point by the ecu acting sort of like a boost cut/limiter. Could possibly be your distributor vacuum advance causing the problem a wide open throttle around 4k and/or injector harness clips or secondary injector.
