Stock r33 and it splutters

[Guest IHaveAnR33]

Is it alright to just disconnect the boost restrictor?? is there anything i should do? My car is stock pretty much, has a HKS super dragger exhaust from cat back standard dump pipe and a k&n pod filter so far. and now it is spluttering but sometimes is fine??????

[Guest IHaveAnR33]

the stock guage in my car read 3-3.5 before i disconnected the restrictor now it goes to 7. if i just bypassed the restrictor and not actually pull the little plug out could that have something to do with the spluttering?

I'd recommend gapping the plugs down to about 0.8mm, other than that some form of fuel controller will be needed. Either SAFC or ECU.

[Guest IHaveAnR33]

what is safc?? sorry am new to all this skyline stuff.

[GTS-t VSPEC]

Your running higher boost now, so the stock ECU overcompensates with too much fuel.

[Guest IHaveAnR33]

i have ordered 6 new irridium splugs and 10.0 top gun leads. will that help it??

[GTS-t VSPEC]

SAFC = Super Air Fuel Controller. It's mad by Apexi, designed to modify to the signal from the AFM (air flow meter) and can be tuned to provide more or less fuel at different rpm, thereby stopping overfuelling etc.

[Guest IHaveAnR33]

what would be a half decent fuel controller to put in my car, would i need to buy other items to go along with the fuel controller

[GTS-t VSPEC]

The new plugs are good, but you'll still need to gap them down.

[GTS-t VSPEC]

An SAFC would do, or you can go for full management if your after bigger power:D

[Guest IHaveAnR33]

Are those fuel controllers easy to install?

[Guest IHaveAnR33]

i would love to go full engine management system, but too costly for now... i just want to get the car running smooth on standard boost. the boost restrictor has a couple of wires connected to it i never disconnected them just disconnect the hoses. should i disconnect the wires as well?

A SAFC is not easy to install, you will need to get a workshop to install it.

Hmm, Sounds like you've disconnected the boost solenoid.

It doesn't sound like you know enough about your car yet to attempt an SAFC install, so it might be worth lettinga workshop do it:D

Dood please dont read some threads on this forum and then start to fiddle with things. After you read somethign interestingl ike a free boost increase and you are really excited about the MORE BOOST aspect that most owners are into. Then first try and find more threads on how all the different parts work that are involved in causing the car to boost etc. then you can do what you like and you will have a fairly good idea about what damage you can cause.

It sounds like you are grasping for cheap mods to do. DONT unless you are sure.

SAFC took me about 1 hour to install. and then i counted 1 wire incorrectly and the car wouldnt start. took me a further hour to find and fix that.

so yeah workshop is your friend in your case, but if you got plenty of time and passed year 2 maths (unlike me) it wont be a problem to install.

peace

Errr what will the top gun leads do?

[GTS-t VSPEC]

I wondered the same thing. I'm sure we use coil-packs, and there not cheap to replace:(

[Jengi]

Your R33 only uses coil packs.

For the spluttering issues, it will either be spark plugs or that a coil pack will be faulty, which will cause a misfire.

Please don't start pulling random hoses and such off the wastegate actuator without properly regulating the pressure, unless you would like stuff to start breaking?

The stock fuel system will run very rich so there is no need to worry about underfuelling, if anything get it tuned with an SAFC (or any decent piggyback or complete ECU replacement) like GTS-t VSPEC suggests.

It is all tuning.

[Guest Robo's]

I had the same problem, installed the SAFC, leaned it out and now it pulls like a dream with so much more power.

IHaveAnR33, You have your answers, let us know how it goes:D
