Tough! Planning a drop & front lip?

Nice ISFBloke. Got mine back from repairs finally! Fitted Project Mu rotors & NS400 pads.

Where you located? Wish these came up for sale a month or so ago.

I'll leave this one to Vaku as I have some headers lined up. Although I know there's another ISF owner after headers. BCHLER, are these PPE headers stainless steel & are they ceramic coated? I believe those are options & it'd be good for potential buyers to know.

Nice! Add GFX rear :)

Congrats! You won't regret going 350. If you had a 250, you'll get bored & want more power eventually. The 350 2IS is plenty fast enough for the street & beats most other stockish cars & holds it own against the rest (within reason of course). I love the diff ratio & brutal 1st gear acceleration (3IS lacks that). IMO, just tint it, get a gfx rear, drop it a bit, exhaust & intake. Rims can come later if you want. You have some good times ahead.

Looks good. Always been a fan of them. Do they weigh a lot?

Using nitrous for sure. The record for all motor no giggle gas is 11.8 on radials (full bolt ons, cold night @ low altitude well prepped strip), outright record with nitrous is just under 11 now I believe. Nitrous systems are smarter than they used to be (used to run it myself - still have it if someone wants to give it a shot), but there's still the obvious problem of not always being able to use it & running out of gas after 10-12 shots. The turbocharged ISF's etc, never appear to hit the drags or track. I wouldn't expect much from them though given they run low boost setups without true/fine EFI tuning. Transmission really wouldn't be a big problem IMO, a solution wouldn't be too difficult. If anyone really wants to give it a go, they can run a standalone right now & ditch some of the direct injection & move to a more traditional/manageable setup (pre injection). Personally, I wouldn't try turn an ISF into a 4-figure horsepower monster. Fundamentally, it's heavy & won't have as much traction as some of the competition. Not to mention the development cost, inherit to being the first to do it. Motor's provided for motorsport (drag racing) aren't packaged ISF motors, but the bare potential is the same. It's the ISF/production model ancillaries that are the complication.

I don't know about 700hp, given the motor isn't suitable to utilise forced induction (high comp). However, if it could be ecu tuned, add cams, additional head work, flex fuel setup, coupled with the usual intake/headers/exhaust.......result would be some happy all motor times. Rebuilding the bottom end to suit turbocharging/supercharging & 4-figure horsepower would be on the cards. 5.0L of displacement will shine.

Darth Vader & the Empire Strikes Back! This IS-F was never destined to remain stock.

I'm sure you like saving at least $7k a rim more than the Lexus icon....haha :) Don't think you have a choice as there's no copies I'm aware for the later model ISF rims. I could be wrong though.

Better off getting a non Lexus ISF BBS rim of a similar design if you don't want copies.

80% at most I meant. The long motor's as you said not even close. The injectors, pump etc are usually @ 80% or less. Although given the very limited power adding potential due to the ECU (meaning majority will be spared poor modification), I forsee ISF's outliving their peers (C63, M3 etc) by a long shot. Just like the original LS400's.

Pm'd.

That sounds right. Toyota generally use at least an "80%" rule to ensure reliability. In that components aren't used near their limit unlike other makes.

Oops....got my month wrong (thought you meant June). Maybe I can go next month.

Shame I can't go. Too short notice unfortunately (not intentional I'm sure).

You're right. I believe they do carbon cleans every service Stateside. I did it too for the last years I had my 250 & didn't have any problems. Actually drove nicer after carbon clean so I recommend, especially if you service yearly like I used to (avg 15k yearly).

Added BC Coilovers, then fitted the Toms front & rear diffusers/lip. Will be aligning, corner weighting & fitting FIGS mega arms on Saturday.

They're as reliable as any other Lexus. Much of the bare engine design had been in play for a while, so it's proven. Some US owners have gone over 200k miles no issues which is beyond any AU cars I bet. As long as it's serviced correctly & not subject to silly abuse or ignorent modification, it'll be fine. Brake replacement parts are prolly the only expensive bit, but you can save some money on that if you're smart & not desperate to get those parts immediately.

I had this problem in winter. Carbon build up. Avoid short cold start & stops (ie to quickly move car in morning), let it idle for a bit & stretch it out with a few nice fully warmed up cycle drives. Carbon clean also helps too.

Interesting....what kinda gold plated aux cables are you using? I've tried a few unsuccessfully but didn't think the top quality stuff would make any difference. I'll go buy em straight away based on what you're saying. Yeah, I know the mp3 file quality would have to be good. My Galaxy Note outputs well.

I have 08 speakers in mine but it still ain't like my 08 250. Did you try a second sub?

What switchable valves are you planning to use? I have headers & another midpipe lined up to go with my Borla, however want a switchable valve to bypass the mufflers for when I wanna be a bit obnoxious :)

They are a bit heavy to lift normally. I don't think you have a problem.
