I got a problem guys , i put an s14 sr into a s13 , now i got a clip and i started it and run it , it was fine , no breaking up nothing , (how u ask i run it , well i just pumped gas directly in ) anyways my point is,this is not the option of fault here ,

Ok so this is the problem , when u accelerate on the gas it breaks up like crazy , and sputters , like the car is holding back , now it has no vacum leaks , the cylinders are getting spark , what should i check again ? please give input , any input at all , thanks !

timing, injector O rings, o2 sensor, Bost leak.

Check the easy stuff first.

Also make sure they ignitor harness is tight & the ECU plug should also be tight.

Do you have a good ground strap from the engine to the body?

Does this happen when you are about to get into boost, or already in boost, or far from getting into boost? be a little more descriptive.

Also, try replacing the MAF sensor.

ok ,the car will increase speed gradually , when u floor it , it would break up and sputter they car just holds back , but if you u step on th gas and gradually increase speed it would go , but still runs like **** !

Try having a dealer scan it with a consult scanner. Check everything related to the MAF sensor, and try replacing the sensor with a friends to see if it runs any different.

Cannsult scanner doesnt work any more when you install the SR. My guess is either you are using platnuim plugs (big no no on SR-T) or you are running the right plugs, but the gap is to large and is getting blown out (think candle) at higher RPM's.

The consult port most certainly works when you install an SR. I wired up my consult port and was able to have it scanned by a friend at the local nissan dealership just to see, plus my home-built consult scanning board works just fine

Everyone and their mother has a different opinion on what plugs to run for an SR20. Do a search, read the results, and decide for yourself.

That said, I run Z32 TT plugs gapped at .028

I would run anything but the generic Bosch no names. They spark fine, but the tips have a tendency to break and they are just overall poor quality.

Post by **RobDET** » Mon Jun 14, 2004 5:24 pm

I run NGK's

WTF are you talking about? The F5DTCs are built specifically for turbo applications. They even come gapped at 0.028, which is what everyone else gaps their plugs down to. They also have specially designed insulator jackets to disipate heat faster.

That should be .028. And the Bosch have a copper core too. I think they're slightly more expensive than the NGKs though.

I don't think we're talking about the same Bosch plugs then. I'm talking about the $1.50/plug cheap generic Autozone Bosch plugs that come gapped at something rediculous like 0.050. And I've talked to 2 Ferrari mechanics who say those are the worst plugs hands down and the tips will break off.

Yeah, we're talking about two completely different ones. The F5DTCs are triple pronged, copper electrode plugs that come gapped at 0.028. They are OEM on Porsche turbo motors, and I had to order mine out of the catalog because neither AutoZone or Kragen had them in stock.

The cheap generic Bosch plugs are pieces of crap.

I use NGK copper plugs gapped at .028 and that's what most people I know also reccomend for our cars. I've also used NGK Iridium's and noticed no difference. To me a spark plug is a spark plug as long as it sparks and doesn't break, so I get something cheap, however I've heard the cheap NGK coppers are the best anyways.

The most important thing is that the plug is gapped right, more so than the brand or material.
