no, im about to buy it on monday. but i called them and they wanted to know question number 3, pertaining to the independant or batch coil firing. i can call my tuner at ISP i guess to find all of these out. but they close in a hour, and i think he went home already edit: i just called, he...

i decided to go with Aem Ems v2 for the 2jzgte part #30-6100 for $1,899.99 new and get a custom soarer to 2jzgte jumper harness for $275 from phoenixtuning.com my question is: 1. Do I still need the hks dli amplifier? 2. Do I need the IAT sensor? 3. Should I rewire my coils to fire...

alrighty, its that time for me to go stand alone. i need to know which aem ems to buy. i tried searching but didnt really find anything. 1992 lexus sc300 mods: walbro 255lph mishimoto supra radiator with autozone automatic trans cooler supra 440cc injectors adjustable fpr plenum intake...

so heat shrink the blue bottoms of the coil packs? because i have about a foot left thats 1.25" from a project awhile ago

yeah, i believe its just the stock pump not getting enough power. i read somewhere that mk4 guys run a thick power wire straight from the battery to fuel ecu or something.. idk ill have to research it more, but essentially the wires deteriorate after awhile and possibly lose the conductivity...

yeah i know what it does, thats why i have it lol. im thinking its the 12v fuel mod that everyone does, supposedly some people have the same issue.. its like how the supra needs a direct power cable because the stock wiring is shit.

plugs - ngk iridium .27 - brand new boost gauge - spikes to 14psi, but i have a boost cut eliminator so its not boost cut and i have a wideband but i havnt welded the bung on yet. i think its the fuel, either the fpr has gone bad or the fuel pump isnt getting enough power in the lower rpm...

recently ran into a few problems with my sc300 1jzgte: the main concern is that it bogs at 3k rpm only.. like it hangs there for a few moments then itll accelerate past it. at which time ill hear a pop,pop,POW.. (itll also start to shutter sometimes, and try to learch forward) and then ill...

turned out to be the shaft behind the key cylinder that turns the ignition switch. its all fixed now

no one..?

installed a new relay and ignition switch. no go.. ughhh

the ignition in my 1jz swapped sc300 stopped working the other day: key in ignition, turn to acc - nothing, turn to start - nothing. there are no clicking sounds from the relay, no cranking or anything. i checked the fuses and they look fine. any other ideas? all of my lights work, the...

i posted a thread earlier but the symptoms have somewhat changed. essentially. when in WOT and in D (doesn't happen in L or 2) my engine sort of hangs and doesnt really accelerate past 4k rpm but after a backfire it will keep accelerating. i installed a greddy bcc and it didnt really seem to...

vvti = toyotas version of hondas vtec

im dumb. its a map idk why i thought it was a maf. i installed the greddy bcc and i still backfire at WOT when its around 14ish psi. now im not on a boost controller it should be stock boost. however it doesnt really lag when i hit the 14psi as it used to (i was hitting boost cut) but i...

isnt it a maf? but ill check. i dont have any vacuum leaks anymore. im nearly positive its the wastegates not opening/closing correctly because if i break boost to 11 psi ill backfire.

i ran up to my local performance place and got a new coupler since one of my couplers was from a intake setup and it kept falling off. got the new one on and it seems to have helped alot with the sputtering. so its either boost cut or my wastegate actuator has gone bad. any idea on if i can...

check my thread. i think im getting the exact same problem as you. i have the same mods as well. it just started happeneing after put my 3" exhaust on. i blew a charge pipe the other night and fixed that.. maybe i still have a boost leak? possibly you have one too.

i just wanted to confirm what im having is boost cut. when i first got my car, sc300 stock auto soarer 1jzgte i would notice a little back fire/miss if i went to WOT at a stop. it wouldnt really do much more then 2 misses. but now i have a good size front mount and a 3" cat back straight...
