Alex1 Posted January 8, 2005 Share Posted January 8, 2005 Hey, so everyone says that the legacy just has a "detuned STi engine..." what does that mean... like we can tweak a few bolts and tighten a few screws and we have 300 hp? or does there engine have diffrent parts like up and down pipes.. ect.... confused, thanks for the info, also if its parts, will it void the warantee? -alex Link to comment Share on other sites More sharing options...
rottenspam Posted January 8, 2005 Share Posted January 8, 2005 There are a lot of opinions about what are the difference between the STI and legacy GT engine's but we do know that the STI and Legacy vary in at least these ways.... Different Turbo VF39 in STI, VF40 in Legacy Different Intercooler Different Intake Different ECU tune. But they do seem to have the same block, and injectors. There has been some speculation the cams maybe different too but this hasn't been confirmed. However with the stock setup it looks like pulling 300hp at the crank shouldn't be a big deal. 300WHP is doubtful with the stock setup. Link to comment Share on other sites More sharing options...
Guest *Jedimaster* Posted January 8, 2005 Share Posted January 8, 2005 Don't forget the (salty) sodium filled valves. Link to comment Share on other sites More sharing options...

firedawgs Posted January 8, 2005 Share Posted January 8, 2005 My mechanic also said this is the first year that Subaru has a electronic variable valve/timing, kinda like Honda's VTEC. Updated my vBGarage: Link to comment Share on other sites More sharing options...
Euclid Posted January 8, 2005 Share Posted January 8, 2005 My mechanic also said this is the first year that Subaru has a electronic variable valve/timing, kinda like Honda's VTEC. Whoa, the variable valve timing used in the subaru is nothing like VTEC. It's only variable valve timing, it does not have "lift" like the vtec system does.

Avishar Posted January 9, 2005 Share Posted January 9, 2005 VTech is like a turbo in that it kicks in and makes a sound that sounds like a robot being chafed with a cheese grater, its like 1000% better than NAWWWZ and adds like 150FWHP when combined with a picnic bench spoiler, tokico struts and a type R badge. When you push the clutch pedal in while you are rolling forward rev the engine to redline then drop the clutch and almost pass someone you can be like I VTECHED YO @$$, or if you lose you can say VTECH didn't kick in, im running lean for some reason!

SpankyLGT Posted January 9, 2005 Share Posted January 9, 2005 The block and heads are identical. Cams as well. The only thing that seperates them is the Turbo/IC/Intake Manifold etc. Both the STI and LGT have sodium filled Exhaust valves. Link to comment Share on other sites More sharing options...
kanoswrx Posted January 9, 2005 Share Posted January 9, 2005 Actually the legacy isn't the first to have the AVCS (valve timing) I believe the STI had it first, along with the WRX in japan before the legacy. Link to comment Share on other sites More sharing options...
firedawgs Posted January 10, 2005 Share Posted January 10, 2005 FOR ALEX1: VTEC is varible timing electronic control. It basically allows the lifter/valves to be opened more when full throttle and above a certain RPM. If you have driven in a honda you can fell it kick in. It is NOT a turbo.

Break Beat Zen Posted January 11, 2005 Share Posted January 11, 2005 Very Torqueless Engine Compensation Yeah pretty much. Vtec is actually technology derived from Hondas F1 race cars. It allows the engine to use one cam profile at low rpms and another at higer rpms to keep power across the whole band. Basically you have 4 cams in a DOHC engine. Before i had the Legacy GT i had a honda with partial built J-spec GSR engine in it. It made 187 whp at 135 tq and ran 13.9 at 98.4 mph all motor. It took alot of money to get it there too. Heh, now i bought the LGT and can do 13.9 stock Link to comment Share on other sites More sharing options...
CritterMatt Posted January 11, 2005 Share Posted January 11, 2005 Where is the love guys. I still own my 2000 Civic. I agree tha most ricers think Vtec is the s*** and makes a Civic fast. But the Vtec system does offer a small punch to an economy car. Case in point I had planned to sell my Civic and keep my wifes 97 Corolla when we bought the GT but after driving it I decided the B16 in my Civic runs better and gets better gas mileage. I just hate having payments on two cars. I guess I must say I Love Vtec. Link to comment Share on other sites More sharing options...
deepershadeofp Posted January 11, 2005 Share Posted January 11, 2005 This may be a dumb question but has anyone modified a Legacy GT by replacing the intercooler, turbo, etc with Sti parts? Link to comment Share on other sites More sharing options...
RobY Posted January 11, 2005 Share Posted January 11, 2005 yes... sombody has replaced it with JDM Spec STi Parts to be exact. Link to comment Share on other sites More sharing options...

plunk10 Posted January 12, 2005 Share Posted January 12, 2005 VTEC was that loud noise that caused smoke to blow out of my prelude's muffler. Sounded damn cool though, and made the car feel like a rocket. Although the LGT would stomp a stock lude, I do still miss that car. Link to comment Share on other sites More sharing options...
O00Coolzero00O Posted January 12, 2005 Share Posted January 12, 2005 Which turbo is larger, the one that is currently in the sti or the legacy?Do you guys also know possibly what tread i can find the guy who put JDM sti parts in his legacy? Im just waiting until some puts out a larger down and up pipe for the legacy to start modifying mine. Link to comment Share on other sites More sharing options...
