My lexus v8 FB build

Are you going to run that as a wasted spark setup then?

TheDriver216 · 12-14-2012, 10:10 PM

what is the potential of the engine?

85turbo12a · 12-14-2012, 11:07 PM

yes induction ignition, waste spark, powerful stuff, will really make you appreciate life when it zaps you

the "potential" of the engine is approximately 600hp at the flywheel depending on how well you can prevent pre-ignition. the engine is all stock with the exception of upgraded valve springs for the turbo application. if a person has the extra $1k laying around a set of forged pistons raises that bar to around 750hp, and with H-beam rods around 850 which is where the cams run out, with cams and a treated crank around 1200+ but that gets very expensive and not worth it, when a stock ls2 can deliver that power for less money, also...you cant plant that on the street. and useless dyno numbers do not impress me.

but what i will ask out of the engine will probably be much lower as the chassis cannot plant that much power on the street and it is a street car with street tires, so a conservative 350-400whp will be more than enough to make it silly with the 375-450 lbs/ft of torque that will go with it from this grunty little engine.

i keep thinking of unique swaps... but when it comes down to a junk yard 5.3 ls motor and a 70mm gettting 600hp no problem it makes other options seem less impressive lol

thats a matter of opinion, im not impressed at all by cookie cutter builds, i dont need that much power so the stock $300 engine with a simple rebuild kit and springs will do just fine, as i would have to do all the other modifications i have done for any other v8, just the initial engine cost would be a lot more as an alum ls2/3 is pretty pricey, so i decided to build something no one else has. and with any luck carve up the dragon with it this year

That... we've done close to 40 LS swaps @ Speed1, it's almost gotten to the tpoint where we can flat rate it which is kinda ridiculous. Personally, I'm looking at a few different non RX cars for a unique engine swap but THIS one is definately unique and one of the cleanest that I've ever seen. Well done sir

I would LOVE to see this thing @ DGRR this year, absolutely love to. Good luck with it.... I would offer dyno services, but I fear a 40hr round trip would be a little too far for you

thanks dude, im going to try to make the gap...i am trying..

i was there in 2011 and saw your car, its fantastic all the right things in the right places.

appreciate the offer of dyno services, but luckily i have a friend in the biz and he is only 2 miles away so basically have dyno any time i need it.

its good to be da machinist...

85turbo12a · 01-01-2013, 11:38 PM

^yeah so my new front tires are wider than my old tires despite being the same 205/50/15, thus creating yet another problem i have to solve...i dont wanna have to buy a different pair of tires but i dont have much option, i cant go out or they will hit the fenders, they were close before im afraid they might hit now anyway...dammit..

85turbo12a · 01-06-2013, 11:46 AM

engine bay is 99.9% complete mechanically, primed the engine oil....and tightened that oil line i forgot

finishing up some stuff under the car, then it is time to run electrical and vacuum line and dump some fuel in it and light the fire!

hoping to have running very soon...
