spark plug question
 

can anyone make any suggestions as to what spark plugs would be ideal for my shitbox?

93 civic hatch...
...stock GSR with a t3/t04 turbo, goin to be boosting 10 psi...

go 1 heat range colder than stock, run ultra 94.

thanx!

yea thats what im using now, 1 stage colder, and i ALWAYS use 94...

look into getting a fuel riser, an AFC or something...maybe bigger injectors(not too big) and get an egt gauge!

already got those covered too... full custom tune, 440 cc injectors, and an autometer EGT... lol...

A 440cc injector seems pretty small for a turbocharged 1.8L that spins past 8000rpm... if you're going to make above 300hp, you're going to need at least a 550cc injector.

well im at 256 right now... i havent had any problems at all... im goin for the 300whp range for the spring... hopefully it'll be ok... hmm

440cc injectors will do over 400whp with the correct turning and fuel pressures.

As far as spark plugs go, run copper plugs for a boosted car. They need to be replaced the fastest (wouldn't go over 10 000km's per set) but they make the best spark. NGK's or autolites, same . Unless you want to be a baller and use iridium plugs.

edit: iridium plugs like to explode over 20psi.

2 step colder are ZFR7F-11
NGK BKR7E-11. These are the 1 step colder plugs

Maybe if he had 2 extra pistons like you have, but 440cc's on a 4-banger isn't going to make 400whp, if they do... your duty cylcles will be WELL OVER 100%, and thats not where u want to be.

With the plugs, like everyone else says, go colder. When running more boost, use a smaller gap.

a stock Pulsar GTI-R with the SR20DET with a T28 with ITB setup comes with 444 top feed injectors and only pumps out about 220 or so crankHP...so yeah...with a bigger turdbo like a T3T4 you'll want at lease like a 550 - 600 to stay safe
