There's a good discussion re wheels sizing at the UK site: http://www.lexusownersclub.co.uk/forum/index.php?showtopic=637&pid=4598&start=&st=#entry4598 They've covered wheel size, offsets, and tyre options. Have you considered sticking with 17x7, but going for some sexy lightweight wheels to shed some unsprung weight? Something like these Enkei wheels (6.2 kilo) I believe the stock wheels are about 10.5 kilo? But I could be wrong.

Thanks for the suggestion ilv, but the main issue is the limited width between the driver and passenger footwells. I'll be removing the battery/heater tray to move the engine as far back as possible, to reduce weight distribution issues, and I'm only left with a trapezoidal space <400 wide at the back, <500 wide at the front, and <600 tall. To give you an idea of how narrow a car we're talking about, The track (front & back) is less than 1200. Most other engine swaps have had to steal space from the already narrow footwells; something I'd rather avoid. Hence hoping I might get away with the slim FE head. And, due to daft restrictions, I can't go over 2.1 litres NA... Thanks though!

Hi All, I've been trawling the net for a couple of weeks now trying to find the exterior dimensions of the 1G engine. I'm specifically after 1G-FE details (going for the narrower cylinder head), but anything would be helpful at this point. To give you a bit of background, one of my cars is a 1965 Austin Healey Sprite IIIA, currently in storage, and in dire need of some TLC. I was considering a new body for conversion to a Sebring Sprite, when I came across the the Works Falcon Sprite (http://www.sebringsprite.com/EdLeavensNassau59.gif). Apologies to the moderators for linking to external sites. Anyway, I fell in love with the look of the car, and I will be restoring the old IIIa in its likeness, but my current 1 litre engine seems wanting; enter the 3.8 liter Jag engined Sprite (http://www.coupers-cars.com/sprite_restoration.htm), I've always loved a straight six, so this seems like a obvious solution. Unfortunately getting the car registered in NSW after an engine conversion is not without it's own difficulties. Because of the original weight of the car (just over 700kg) I'm limited to 2.1 liters NA or 1.7 Liters forced induction. The answer? 1G-FE. (I hope) Before anyone suggests it, I think the 3S-GE is probably too wide, and too expensive. In short, I'm planning on turning my 1965 Sprite into a replica of a 1959 Works Sprite, and replacing the engine with a 2l Straight Six 1G-FE. I've managed to source either the engine alone ($500) or a half cut ($2500 - $3000) but I'm not willing to part with my money until I'm sure of the fit, and the parts I've found are all interstate. So, to return to my question, I'm looking for the dimensions of the engine: 1. from bottom of sump to top of rocker covers 2. length from bellhousing to belts, and 3. width from manifold to manifold. I'm not suggesting anyone head out to their garage and measure their engine (unless you want to), but if anyone has this info it would be a great help to me. Obviously I'm going to have issues with the ECU (I've never had a computer controlled car before, and it seems a long way from tuning twin SUs). I am, however, a programmer by trade, so I'm sure I'll be able to muddle through the ECU tuning somehow. Probably just need to find a way to avoid the engine fault codes for all the sensors I won't have, like ABS etc. etc. And I'll definitely need some kind of aftermarket ECU. Just for fun, I also estimate the new fiberglass body will take my kerb weight down under 650 kg :D Cheers, and I'd appreciate any thoughts.

Hi All, I'm not quite a Lexus owner, but I am planning a straight six conversion to my old sprite, and I'm considering using a 1G-FE from an old IS200. I've seen a great straight 6 conversion using an old Jag I6, and, being constrained to less than 2.1 liters naturally aspirated (or 1.6 turbo/super) due to the light weight of the car, I thought I'd go for the 1G. I have some questions about the engine dimensions and other details, and no doubt (if I do decide this is the engine to use) I'll have a million more questions once I get started. I'll post those questions over in the IS200/Altezza forum, but thought I'd just drop this intro in here to say G'day. Great Forum from what I've seen so far, with some really knowledgeable folks. Cheers,
