ontherun987 Posted May 20, 2012 Share Posted May 20, 2012 I have a 1987 gl with stock carb, I am wondering about the weber carb. does it increase power? and if so does it lower my mpg? What is the main reason for doing this? Thanks for any and all input on this Quote Link to comment Share on other sites More sharing options...
Subruise Posted May 20, 2012 Share Posted May 20, 2012 low end grunt goes up, gas mileage goes down. peak hp/torque are unchanged or changed very little. why do it? because the hitachi sucks. like really sucks. if it were up to me and my car id convert to spfi. it can e done for the same $$ or cheaper and it gets better mileage over the carb. you could also swap in spfi pistons which, iirc are higher compression. hth, RV Quote Link to comment Share on other sites More sharing options...

92_rugby_subie Posted May 20, 2012 Share Posted May 20, 2012 Depends on its tune, jetting and your right foot. I can go 208 miles on a tank in town hammering the accelerator every chance I get... I also ran a friend around the oregon coast. Total of over 800 miles... two tanks (mostly highway) This is on my EA82 sedan with 32/36DGEV Quote Link to comment Share on other sites More sharing options...

92_rugby_subie Posted May 20, 2012 Share Posted May 20, 2012 I believe Im running rich, I can watch gas drip out of my exhaust at idle every couple seconds. Ask GeneralDisorder about the Jets on NED he installed the weber and tuned it when he owned the car Quote Link to comment Share on other sites More sharing options...
Moosen Posted May 21, 2012 Share Posted May 21, 2012 Way more power. Sounds beautiful... especially when that second barrel opens up Greater power band, from about 1500 rpm to 4500 rpm Increased gas mileage from 23 mpg to 27 mpg on freeway. and stuff still isnt hooked up or jetted right. Easier to work on removes a lot of bull************ conversation starter Quote Link to comment Share on other sites More sharing options...
ontherun987 Posted May 21, 2012 Author Share Posted May 21, 2012 any thoughts on the cost, how much from start to finish? Quote Link to comment Share on other sites More sharing options...
Moosen Posted May 21, 2012 Share Posted May 21, 2012 any thoughts on the cost, how much from start to finish? cost me a little under $300. $200 for carb, filter and adapter was about another $50. Then miscellanous parts to get her working right. Quote Link to comment Share on other sites More sharing options...

spazomatic Posted May 23, 2012 Share Posted May 23, 2012 I love my weber. driveability is so much better, and it does have more low RPM torque. I average around 25-26 mpg, with mixed in town, highway and back country road driving. I expected to see more power in the upper RPMs, but no. I even passed emissions with it!

Yeah not much more in the high end but it sounds a lot better up there Quote Link to comment Share on other sites More sharing options...
92_rugby_subie Posted May 24, 2012 Share Posted May 24, 2012 Depends on your exhaust for sure... The weber on my 84 GL sounded good up front with the secondaries open but the exhaust sucked... same story on my 84 DL... Now my 86 GL NED sounds sooo amazing but I cheated haha...

Doubt it, down pipe is where the turbo and headers meet isnt it? You dont have a turbo... Id just get new exhaust from the y-pipe back to a decent muffler and itll sound better.. Back on topic... Go with the weber, you WONT regret it... itll pay for itself in sheer smiles on your face when you open the secondaries. Ive been driving cars w/ webers for 2 years now, 3 vehicles and have loved the feel of each of them! Quote Link to comment Share on other sites More sharing options...

"Stock 04 wrx" isn't turbo'd, I'm probably missing something and there probably is some stock wrx with a turbo but I really don't think so Quote Link to comment Share on other sites More sharing options...
92_rugby_subie Posted May 26, 2012 Share Posted May 26, 2012 a stock 2004 WRX is turbo'd - the TD04... but we need to get back on the weber topic Quote Link to comment Share on other sites More sharing options...
TomRhere Posted May 26, 2012 Share Posted May 26, 2012 ont hat note. sorry to threadjack. my buddy has a down pipe from a stock 04 wrx. would it fit? With a whole lot of cutting and welding and bending,,,, it could be "made to fit"..... But it ain't no bolt-on for a Carbed engine, nor a FI engine,,, unless it's Turboed..........
