  1. need ISC help

  2. 4g64+ 92 gsx???

    i think if your just looking for a cheep stroker. just use the crank that will cut way down in your custom stuff and you can put more money into new parts and have your self a nice little motor thats fresh, has squirters and no custom timing personally i don't think bigger displacement is...
  3. need ISC help

    awsome guys thanks for all your helpok so the ISC i swapped to is bad the brown top readspin 1&2=open 0 ohms 2&3=28.9 ohms 4&5=28.2 ohms 5&6= open 0 ohmsso im assuming in trying to fix the idle surge i swapped in a bad ISC and blew my drivers in my new eprom ecu when the problem was some...
  4. need ISC help

    haha yeah man that was the first thing i tried but it was a parts motor that "was running when pulled" crap so who knowsi guess my book kinda worded it funny and it covers 1.8 na 1990 and 91+ turbo isc and connectors witch are different so its a little confusing and i started second...
  5. 4g64+ 92 gsx???

    yes it will work fine. the blocks are basically the same, trans bolt patters and head bold patters are the same. allot of guys will swap out the 63t block in favor of the 64's bigger displacement. it will lower your redline a little because of the longer stroke but you will gain a cheap stroker...
  6. need ISC help

    ok so i have some bad idle surge i suspect its the isc or rather the wiring to the isc ( i have replaced everything so its got to be a wiring issue i have 0 boost/vac leeks) sometimes when i drive for 30 min or so it will idle just fine, but not always more often i pull up next to a car most...
  7. 1g cas reads 3.7 volts whats wrong?

    would low voltage hurt my car? i haven't had any issues with detonation ...just low power and bad mpg. any chance you know what the wire color is for ECU to CAS im missing my wire pages out of my book. i also plan on getting link if i do have a hardware/driver issue would they fix that? my buddy...
  8. 1g cas reads 3.7 volts whats wrong?

    yes but i also measure through a cut someone else had made with it connected but not running guess i could try running, i also had to fix a bunch of bad grounds. and yes that's what i was told and why it concerned me that it was only 3.7 or so
  9. 1g cas reads 3.7 volts whats wrong?

    im measuring the connector to CAS i don't have the book in front of me but there are 2 pins that are supposed to measure somewhere around 5v with the key on so i have 1 pin ground :ok 1 pin @ 12v :ok 2 pin @~5v: both at 3.7i would think that my CAS would set off a CEL no?i have...
  10. 1g cas reads 3.7 volts whats wrong?

    like i said the cas or cps what ever we are calling it reads 3.7 volts my book says it should read about 5 what should i check? i swapped my manual ecu to my stock automatic ecu and the ecu clicks after a few seconds and the car dies. same reading on the cas tho i have bad idle hop at all...

  12. 1g at difficulties

    thanks for the effort guys i appreciate it! i ended up pulling the motor back out and getting the torque converter to actually sit right that was my whole problem. after that it was a snap i dropped it all back in solo :hellyeah:
  13. Help! oil pump lockup?

    If you cut your old shaft make sure you plug the oil suply to the rear of the shaft with a metal slug. For the clean look remove the top shaft pull the berrings and instal soft slugs. Instal a freeze plug In oil pump case I think its 35mm lock tight is your friend .use caution as the metal is...
  14. 1g at difficulties

    hey guys i have a 91 gsx automatic i was having trouble putting the tranny on the block when the block was on the cherry picker i couldn't really push on it and when i did get it to kinda go on it would stop about 1/4 inch from being fully mounted. so i figured i would drop the motor in the...

  16. mismatched valve question. and valve-train rebuild Q

    sorry for the pics not working.... i forgot to upload them sounds like a unanimous no go on the valves. i had my doubts, i did notice the exhaust valves were much beefier around the stem. wishful thinking i guess, would have kicked ass if it could be done! thanx guys
  17. mismatched valve question. and valve-train rebuild Q

    hey guys lay some knowledge on me! (history) i bought a 91 gsx with bent exhaust valves... timing belt slip. Bought a new motor with some block issues. The plan is to swap heads and refurbish long block seals, rings, bearings,studs,mls gasket..the works#1(pic) the dish in the valves of...
  18. how do you know if you bent a valve

    if you have a funny idle and your afr gauge is flipping out i would tend to think its a leek after your air has been metered out by your maf. i bent the valves in my gsx and trust me ya know when they bend ( catastrophic failure in my case) your timing belt would have to slip so check that also...
