83_project_toy Posted April 1, 2009 Report Share Posted April 1, 2009 cars very sluggish below 3100 rpms wont go over 2k rpms with the gas padel smashed and foot on the brake. takes off very slow from a stop no matter how much gas you give it. now the fool mix of my know parts in it good 87 short block new trilogy injectors new injector clips 83 head 18g turbo since the 12a had a cracked housing but starts making boost at about 2300 rpms on the stock gauge full boost on gauge before 3k msd blaster 2 coil new cap and rotor above 3k rpms the car screams and seems like a normal starquest. there's just no power below that. was told tranny was rebuilt about 1k miles before the motor went. tranny shifts great from 1 to 3 havn't tried OD yet. new setup was put in completely stock Link to comment Share on other sites More sharing options...
BaltTSI Posted April 1, 2009 Report Share Posted April 1, 2009 What makes you think it's the tranny? if your not sure post this question in the mechanical forum Link to comment Share on other sites More sharing options...
IntercooledFlatty Posted April 1, 2009 Report Share Posted April 1, 2009 3.90's will help :thumbsup: Link to comment Share on other sites More sharing options...
83_project_toy Posted April 1, 2009 Author Report Share Posted April 1, 2009 (edited) not sure what it is only driven 5 speeds in these cars. motor seems fine in park and neutral. mostly just wondering if it's normal for a auto car to take off so slow. i do have one question is the timing set at the same point as the manuals? i know 3.90's will help but thats not at the top of my list right now. tires Edited April 1, 2009 by 83_project_toy Link to comment Share on other sites More sharing options...
BaltTSI Posted April 3, 2009 Report Share Posted April 3, 2009 Its hard to know what your feeling as "slow" but what are you comparing it to? do you have another car? does it feel faster or slower than that car? Link to comment Share on other sites More sharing options...
83_project_toy Posted April 3, 2009 Author Report Share Posted April 3, 2009 compairing it to a 83 stock and modifed and scotty's turbo's 2.6 truck. the car feels very sluggish coming off the line. it's going to get inspected today so maybe after a nice drive and more fresh gas i'll see if anything changes Link to comment Share on other sites More sharing options...
MikeMeyerhoff Posted April 3, 2009 Report Share Posted April 3, 2009 Comparing my 84s, auto vs manual I'd say no there isn't that great of deal of difference between the off the line <3000rpm accelleration. The gearing is a little different between them, but the "torque multiplication" that happens due to the torque converter helps down low some. Maybe it distributer related? If its gummed up, that could cause poor low end. Link to comment Share on other sites More sharing options...

Zack_Morris Posted April 5, 2009 Report Share Posted April 5, 2009 The stall on the factory converters is 1750-2100rpm, there's no reason for it to go over 2k with the gas and brake applied. have you tested the wastegate actuator to see if it holds pressure/vacuum?

83_project_toy Posted April 7, 2009 Author Report Share Posted April 7, 2009 don't gut the second one just yet. is there a difference in how it runs with the dp replaced? with 2 gutted precats first one broke and the 2nd one with no cracks the car runs the same. i know this turbo and it's spooling way faster then it did on my 83. so thats making me think the cats clogged.

FijiPhil Posted April 11, 2009 Report Share Posted April 11, 2009 I know the ISC is bad on my palermo car, it wont idle for crap til its warn. No real driving effects though, just idle. Have you tried pulling the OD relay? Its located next to your left foot, i know a lot of people can make their OD work by pulling that. Link to comment Share on other sites More sharing options...
