Thanks for the help anyways even nobody responded to this thread.... i figured it out im guessing nobody knew how to fix this issue, well it aint even an issue or something you can fix./... its just about knowledge....u know persistance here and there....patience... -----> to the point: aightt for all the begginers like me with these cars...(Z31-300zxt's) the best thing you can do...to start of: Get a Manual boost controller, a good boost gauge, k$n filter... make it cold air intake by covering the holes around the shroud everyhole possible (do this if you just starting....and want more speed, power, everything...for the moment...in the meantime before getting intercooler...or anything else...) and dont forget to cut the rev limiter in your eccu the upper plug has a purple wire, cut it and put sum electrical tape, that's it... and if you want cut your catalyc conv. too and just weld a straight pipe... with this I already smoked earlier 90's Mustangs GT's.... Gs'ts Tsi's.... Mazdas 6's and 3's ohh and also not to forget lots of honditas....good luck ya all.....

is cutting the purple wire a good way to get rid of the rev limiter? is it safe?
doesnt seem very smart to me...

 

Dont get scared with the word "Cut".... i did it on mine and flies now...as well for safety>>>> don't forget to put some electrical tape.... another tip.... Run the self diagnosis if you bought the car from unknown like i did...its easy and it will tell you watup... i did it today and it told me that my fuel temp sensor was bad... unfortunately u can't buy just the temp itself,... so i went ahead and bought the whole fuel press regulator $69 and replaced as well the old hoses... make sure your plug of the temp sensor is good and making contac... with this replacement my car is runnig at first gear 39 miles per hour without intercooler at 7 psi. and no blow off valve.... second i hit 66 and the other gears for safety havent try them yet... but just wait 'til i get the intercooler...... gonna be racing vettes soon...... a whole project with patience....

i dirve a non turbo 88 would it still be the same wire?
thanks in advanve all info very helpfull

 

im pretty sure its the same one.... check the eccu looking all the connectors... if there's a purple wire on the top plug first one from top to bottom... its's the same thing....

 

wait.....why do you cut the rev limiter...its there for a reason???????explain please

 

the same word "Rev Limiter" tells you all... after i cut it on mine dam u feel the difference in every gear.... you actually rev more so with this mod your car is gonna run faster every gear.... be carefull dough... you gotta know how to rev it and your car limits too... it all depends on how well your engine is im talking about physically... makle sure to put a bottle of lucas oil in the engine this protects really good... or if you are close to the oil change add a bottle of lucas oil... make sure is the lucas oil for engines dough cause theres one for transmission... you can find it at any autoparts.... don't start overreving it right away.... if you cut the cable.... you gotta let your engine get used to your driving doug... little by little start overreving it for example.... 1st gear go to 4k 2 nd go to 4k 3rd gear 4k and so and so.... do like sessions... then the next session go 1st gear 5k 2nd gear 5k and so so.... no need to speed do it slowly.... ull se the difference right away.... good luck...

no....noone listen to this...HAVE YOU EVER SEEN A DYNOGRAPH?!?!?!?!??!?!?!?the hp line will drop dramatically around redline...going past redline will only drop it further and with the rev limiter at round 56 to 5800 this is where the car is safe any past that....hence the redline....you begin risk breaking engine parts....thus this mod is complete bs and its useless.....NOONE TRY THIS

 

yo well see when u get your turbo z.....

 

i agree the rev limiter is not somting you shpuld mess with. if you want a littel more r's then just simply go buy a after market ingntion box. i put a msd in mine a 6al to be exzact. it alowed me to chose my rev limiter point. dont be a fool. rev limiter is there to prevent major hart acke

 

sounded to good to be true...
thanks for keeping me from doing sumthing stupid to my car guys.

 

im sorry 86 but no...this is simply put not a good idea...rev limiter is there for a reason...overrevs blow engines.. dont mess with this part...and if you do dr.buddah seems to have it figured out with the new ign...have him help you out
