3S-GTE JDM 3rd Gen Turbo Engine gen III won't rev past 6000 rpms

e30 · 03-07-2009, 08:12 AM

i finally got my car road worthy for bc and insured. but after driving it, i was slightly dissapointed. when i first test drove the car, it was pretty powerful, but now it doesn't feel nearly as quick as when i test drove it. i tried taking it up to red line but it won't go past 6000rpms. i'm thinkin gits in some kind of safety mode. the car was sitting for about 10 months so the gas could've been bad but i filled it up with a fresh tank of 94. any ideas to what's wrong? i'm thinking something with the ignition?

any error codes stored?

If you're worried about the ignition stuff then check it out.

Pull some plugs and take a loot at the wires.

One sign of bad ignition set up is that the problems are usually more pronounced at low rpm, it may have a slight miss, or run a bit rougher, and get a bit less power at low rpm.

Another thing could be the ignition timing, i take my car to toyota to get ignition timing done, but people seem to say it's pretty easy to do yourself.

What did you all do to get it road legal? How did you sort out the CEL?

e30 · 03-07-2009, 04:34 PM

i bought the car with the owner saying that the fed was done but hwne i went to the insurance place, they said it wasn'nt. apparently that insurance placec didn't knwo what they were doing. the shop that was doing my provincial brought hte form one to CT and theys aid it was done so i lucked out i guess.

ebouwman · 03-07-2009, 05:00 PM

nice!

Good to hear.

e30 · 03-10-2009, 11:54 AM

i'm thinking its most likely ignition. the car is getting crap mileage... so far 80 miles and its at half tank haha

PearlJammzz · 03-10-2009, 01:01 PM

Could be ignitor... people who do gen 2-3 electronics conversions who don't use the right ignitor give themselfs a 6k rev limiter.

I think it's your fuel system, one of the sensors is out of wack i bet. Cause i was getting SUPER bad gas milage like that, and when i finally replaced my oxygen sensor it fixed it right up.

If you're worried about the ignition, then set the timing again

******... is the o2 sensor the same as the gen II's?

Landjet · 03-16-2009, 06:20 PM

Yes the o2 sensors are the same. Can you free rev it (car sitting still in neutral) past 6000rpm?

e30 · 03-16-2009, 07:26 PM

where can i order the o2 online? i'll try free reving the car the next chance i get. i doubt its the ignitor, cause the car WAS powerful. now it just seems capped. gotta wait till after exams are over before i can any work to the car =(

ebouwman · 03-16-2009, 09:25 PM

you can just get one at a parts store, they're a little pricey, i paid something like 65 dollars for mine, but i was running it through a business account from where my mom works, expect more like 100 dollars or a little more, not sure though about the one for your engine.

Oh and the O2 sensor is pretty easy to change, at least it was on my mk1. You just need to jack it up and get passenger side wheel off, and get in there under the car. I found the hardest part is messing with that stupid electrical connector to disconnect the old one from the harness. But that's just because i fail at pulling apart electrical connectors

Landjet · 03-17-2009, 08:49 AM

You will be installing this MKII O2 sensor form the top of the motor.

ebouwman · 03-17-2009, 11:10 PM

aha, that would make it even easier

Lindsley · 03-21-2009, 11:34 PM

You need the Gen III Map sensor and Ignitor to Rev pass the 6000RPM

e30 · 03-29-2009, 05:27 AM

regarding the o2 sensor... i think it might be that. i see a sensor that's plugged into the exhaust with the wires cut. how would i wire it back to the ecu? just to make sure the o2 sensore where the DP is right?

e30 · 05-12-2009, 12:13 AM

anybody have the parts number or a substitution number for the o2 sensor? teh one i got in the FAQ is a japanese parts number. the dealer can't find it...
