well 2.4 liters is a nice size engine, and with bigger engines, you need more fuel. the engine is also not the most efficient in the world.

I get usually about 325-350 per tank, before I got what you got, 250 max from F to E. All I did was run some sea foam through the vacuum line of the brake booster and after all that smoke comes out, I thew in a new O2 Sensor and "BAMM" gas milage galore, I have 169k on my 93 240.

240dreams-im not sure if you can or not, but im gona go ahead and say no because if it smokes alot of the carbon out, it may get all up in the turbo and screw up its efficiency or balance.

sohc90adel- i cant find the stuff around here either, but if i come upon some i will drop you an email

You can use any kind of intake cleaner as a substitute. I'm not exactly sure on shipping limitations on a flamable product such as Seafoam. If nothing else works, e-mail me through Nico here and I'll help send you a bottle.

Seafoam in SR20DET is fine, if you use it through the brake booster vacuum line. We do it all the time on my friends car with an SR20DET.

WEll, I get 325-350 now. I average 24-27 mpg. I recently changed the timing chain and before it was just a couple of mpgs less. But still in the worst I never got less than 300 EVER and I drive mine like its stolen. Seriously I redline it at least once everytime I am behind the wheel and I drive at least 82 miles a day (thats my roundtrip to work and back). And by the way I have 143k on my '90 fastback.

Oh and p.s. most of my driving is on windy country backroads with lots of shifting and constant acceleration and deceleration. I have used 2 sets of tires in a years time and I have put 50k miles on it in 1 1/2 years.

hmmwell I used to get approx 70miles from full to 3/4ths full but when I put on my hks exhaust, I barely get like 40miles through that 1/4th, which is killer with these damn gas prices..any ideas? the only thing I can think of it being is the exhaust.:( which sucks because I don't have my old one now

I got the helical LSD from some guy on ebay that was in japan, it took like a month to get but when i got it i just got my dad which is a mechanic and he opened up the pumkin and swithched the differential. I am also in aguadilla on the weekends. I have no idea which skyline the lsd is from.

Their site does not sell it, can't send flammables in mail, but can find place that does near your location. Make sure to follow directions on the bottle. It is possible to hurt your engine if you use it wrong.

Sohc90adel, you DO NOT need to buy Seafoam. My best friend is a Mazda RX-7 Fanatic and he shared some information with me regarding "Steam Cleaning" your engine. I have performed this action on my car and I swear to god I went from 23 mpg city to 25 mpg. All you do is remove your vacuum line from the brake booster, get a very clean bucket and fill it with roughly 2 gallons of tapwater. Get in the car, rev and hold at 4000RPM and then have a friend place the hose into the bucket, but only enough so that the engine does not stall out. Run all 2 gallons through the vacuum system, leave the car running and watch the carbon pour out of your exhaust. My car has over 183k miles on it and I do this every 6k, trust me, your car has never run better. Just don't do it at night, my neighbors hated me for running my 110dB exhaust at 4k RPM at midnight for 30 minutes

Careful with the water. Hydrolock will total your engine, but I have heard that before, just too paranoid about water to even try it. LOL

Water injections is a fine spray to lower intake temp. It's a very small amount and in mist form, not much worse than a real humid day or climate. But putting in a large amount as a way of cleaning runs the risk of hydrolocking.

You can get seafoam and Oriely's or NAPA. Ran a bottle through booster, and gas tank, only boosted my milage maybe 1 or 2 per gallon. but when gas is $2.04 it helps!!

SOMEBODY GET BUSH OUTA OFFICE SO GAS WILL GO DOWN!!:help
