20 years! Wow Lexus has comes a long way. The new LS is just absolutely beautiful and very powerful. As we can not afford the newer LS460. However, the 1989 to 1997 LS400 is very affordable. How can we the owners of the classic LS compete with the newer LS? I really dont think we can. The 8 speed auto is just too awesome. However, we can have some fun with our historical cars. The figure I come up with (5.2L stroker with high compression pistons 12:1) yields about 350 bhp. I wonder with good intake, high flow exhaust, cams and valve will propel the classic to late 300 range. What do you think?

that would be sick!! do it!

It appears that you have really answered your own question.

There is a LOT more in the 460 than horsepower

The truth is no one can make a 10 year old car new by adding some new parts.

^fully restore it, then add couple new engine parts

Can you run pump fuel on 12:1 compression?

Im an old school cast iron v8 man, They highest we can get is around 10.5:1. I assume the alloy contruction would retainless heat and would be better suited to higher compression is that correct?

Any links to more information on this 5.2litre stroker?

5.2 stroker kit for the 1UZ?? alright

For the tuners they may enjoy massaging the ol motor. How about a stock 1UR-FSE transplant with tranny? Such a beautiful engine...to bad they put all that plastic over it.

I was trying to install the 1URFE (Engine from the 2007 Toyota Tundra). It is a HUGE ENGINE and lots of cutting for the tranny tunnel. Not worth the work. However, a high compression 5.2L will be direct bolt on.

That motor is huge. I bet the LS460 tranny is an equally huge combo too.

I'd still like to see some baseline dyno numbers for simple mods: muffler removal, cat back, header, intake, head porting. Let alone OS valves or altering cam profiles for lift-duration... What is stock...~60HP/L, the second gen bumped it about 64HP/L on factory numbers. I'd think there is room to grow with some engine management tuning.

can someone tell me more about the 5.2 stroker? like 1UZ stroke to 5.2? or are you guys talking about a whole different motor?

Lextreme

Do a search on the web and I sure you can find it. 5.2L with high compression will be very fun. Especially for a cruiser like the LS400. Tons of torque.

MEANDAFAKA

seems familiar, and bamm when i look up lextreme again. i found the stroker kit and the 5.2 short block. its not bad for what you get for the price

Too bad there are not easy available mods for big gains - not enough people are like we are wanting a one off LS with big power - big enough to drop Euro sedans.

Well not just power, but the LS460 has so many refinements in the interior, that are just impossible to install in an old vehicle.. and trust me, I tried.

I did a brand new full leather interior, build new door panels to accomodate larger speakers, rewrapped the door panels when doing so, bought a wood grain shifter. It's still tough to get that plushness in your interior after so long. I came close though

Yeah, the age and later trends do build in some nice features. Short of gutting the interior and swapping in new stuff from the 430's and 460's...that's more $$ than the ride is worth. As far as a daily goes. If ya have the $$ and want that uniqueness...
