is that true 13.00 sec quarter mile with a NA L20B???????????????and 12.00 1/4 mile with 50 shot nitrous..please i need feed back.....?????

it all depends on the car.

you have a ute (or truck - whatever) so traction will be an issue.

in the land of 1000hp GTRs and 9sec hondas / RXs, even a 14sec quarter seems slow. it seems people have forgotten just what kind of trouble that 'just' a 13sec car can get you into.

in something as traction-less as a flatbed with enough power to run a 13sec, you're gonna have trouble running a 14sec quarter. power is one thing, traction is something else entirely.

Quote:Modified L20B ... and that's in a 1200. Your 620 probably weighs close to twice as much as a 1200, so performance would be half as much

i think my 620 wieghs about 2320lbs...thats not too much..and with slicks,traction leaf spring,and some link suspension what do you think..

Just in case anyone got the wrong message, its not my ute that does 13's...
This ute does tho...

one day...

take a look at that link below from dazzasute!!if that ute can do a 13.00 1/4 mile my 620 can...right..or why not..that proves somthing...or..

i know it ain't that easy but now we know..

Why not? Your 620 -- light as it is -- would still weigh 600 lbs more than the Datsun 1200 ute in the photo ...



1200 pickup aruba

how much will 600lbs have an effect??just a guess..maybe i can hit the 14.00 sec????

or otherwise how can i lighten up my 620????

but really how much effect will 600lbs make?????

Hey L18_B110
I agree with you. The L Series motors are THE BOMB.

As for DD stating that the L series motor are noiser and hard to work on compared to the A series, I DISAGREE.
Its just as easy to work on as an A12, the only thing is its size mainly.
L series being noisy, not if well tuned.
Unlike an A series, crying its guts out at 4-5000+ plus revs on open road. The L series are quite.

Why hot up an A series motor, this is so much time and money spent, and not forgetting, that these motors lifespan is shortened by these mods, just to be a fast as an L motor or slower.
Just go L series motor, even without any hotting ups, youll be happy with performance, and you'll also get reliabilty on these motors and gearboxes.{thats if you want to do all the body and mounting mods}

I'm not too sure about that... an L18 with a single weber, how many hp would that be, 140 max? People have got up to 200hp from the mighty A-series. And they're lighter to boot.
Don't get me wrong, I love L-series, I have two of them, and I love Harry's coupe, but I think a modified A-series would be better bang for buck up to about 160hp. That's just my 2c...
