Hey, my names James, im from the Gold Coast in Australia, have been reading your forums for almost a year now and finally decided to join as I have some pertinent questions ![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
I currently own a 1998 Subaru Impreza WRX (Rally Edition) and have been offered the opportunity to trade (plus a cash adjustment to my benefit) for a 1991 Lexus LS400.
This is a very tempting offer to me as I yearn for a nice cruising car and this thing is PIMPED, 3 x Screens, 18 inch mags, dumped on its ass, twin exhaust, leather interior (retrimmed) etc
The only things that turn me off are the fact my WRX has just ticked over 120 000km's whereas the Lexus has 180 000km's, plus the WRX is much faster, and I have ALWAYS owned performance vehicles and know I will be pissed with the lexus's sluggishness.
Question 1: With 180 000km's on the engine, how much longer can I expect the V8 to run well and survive, it seems to be of good health and has a full lexus service history which is very impressive, however im afraid I will go swap a relatively new car and then in 20 000km's time have nothing to show for it.
Question 2: I would obviously look at rebuilding the 1uzfe before any forced induction modifications were undertaken. Approximately what costs are involved in Rebuilding the bottom end and freshening up the engine.
I am well aware of the processes and parts involved, I am just looking for approximate costs as I havent had experience working on or buying parts for a 1uzfe before and ppl I have contacted so far have been vague and unhelpful.
Basically after costs for stuff like Rods, Pistons etc
Also how do the 1uzfe's perform in an LS400 standard, I have standard power figures/specs etc, but as a first hand experience I would like some feedback. For the time being if I decide to go ahead with the trade I would be hoping it is very smooth and cruisy with enough pick up to still put a smile on my face on the highway.
FINALLY, I have left over parts from the WRX, most of which I will sell some of which I thought may be helpful and useful for the 1uzfe, the main one was a 400hp rated VF22 turbo.
I was originally going to just sell it and use the money to start stockpiling parts for the Lexus but thought If i purchased a second turbo it may be suitable for the TT conversion when the time comes. Would this be a suitable turbo, im after power figures of around 500rwhp (long term) with an initial goal of (300rwhp).
Please feel free to add any input or ask any questions as I have been thinking and dreaming of a twin turbo 1uzfe project for some time now and im beginning to get excited now it is coming to fruition. Unfortunately excitement sometimes makes you overlook things...
*thinks back to his last rotary conversion into a 1977 Mazda 323*
One last thing, drivetrain wise, what will a standard LS400 diff, tailshaft, and gearbox be able to handle power wise before it needs to be improved/modified with shift kits, stall converters, replacement gears etc ?
Sorry for the long post thought I'd better make my first one a good one, thanks in advance for the help![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
