most exhaust popping/back firingis caused by exhaustvalve problems (ie. Burnt vavles, weak valve springs, loose valve guides, etc). But not always, best to get a pro to check it out and be sure though.

 

i need some answers

 

my friend has a 240 with a sr 20 engine swap. its turbo. his backfires. it even spits out flames whenever he shift in really high rpm's i asked him why it does that and he said it does not hurt the engine. he has an upgraded Beeline rpm changer. that allows him to redline at 10 instead of 7........ but thats all i know

 

I thought RedV6Pony's dad was a mechanic...can't you just get him to take a look?

 

he is but he lives like 10 min from me lol but il have him check it out thursday if not before, but on thursday redv6pony, freewilly, and myself are gonna meet, and hang out, im sure you'll see pics or possibly video's

 

sounds good.
