Sell the sidies and get a Weber 32/36 downdraught. It looks close enough to a stock Aisin carb but performs better, and you can fiddle the stock round aircleaner onto it.

Certainly get the exhaust quiet, then wear a hat and a fake grey beard.. It all depends on how you drive it, and what time of day you are out there... I've never been stopped in the KE, but I only drift around traffic islands when there is no traffic around and I'm not out doing laps at night. You only have to ask yourself what the cops look for- Noisy exhaust, too low, fat rims, car is racing another, car is drifting around corners, car is travelling faster than other traffic, car has 'P' plates...

I got my double choke cable from my local car parts place, Midstate Spares, so there are suppliers making cables up out there.

Only the bit that fits inside the gearbox as I remember. I put the front joint of the manual onto the auto driveshaft and used that..

interesting- you can ruin your Altezza with a pod filter sometimes, it just depends on the air flow across the MAF. Some guys fit one with no problems, others can't get them to run right. We've quite a lot of posts about it.

Here-

I can't remember which crossmember we used, someone else might know. We're still running the auto diff. Its a 4.3 compared to the manual's 4.1, so it is a little lower geared which gives you better acceleration around town but higher revs on the motorway. Sorry BlueK, I was away in April & never saw your post. I'm sure you have the wiring sorted by now!

Well, I figure black smoke is too rich, so a dyno run or mixture display will soon tell you. If it wasn't really black smoke, then grey smoke would mean the rings are worn. If you could take it for a spin with a plug spanner in your pocket, just give it full throttle in 3rd then turn the ignition off at 4000-5000rpm.and push the clutch in. Coast to a stop and pop the spark plugs, checking the colour of the outside rim and the ceramic core. The edge can be black with soot but no oil, and the core should be white or light tan coloured. A plug cut like that means you are seeing what is happening under power, rather then at idle when there is no load on the motor. Idle shouldn't be set to 2000rpm, so either there is a fault they are trying to cover or something needs re-setting.

Is that the one where you could see the head lift on the dyno?

Ah- he would have it pretty right. I reckon float level or needle & seat must be just flooding petrol in there. It will be interesting to find out in the end.

OK, here's the translation of what your $12.5K buys..

Well, how much will you pay me to pull the 3SGE out of my Altezza and drop it into my KE70...?? Then I can tell you exactly!

How far out can they be? They would have been jetted for a 1600 or a 2L from factory. Take a look at what they are, The mains should be around 135-140 & the airs around 160-170

That will be interesting.... We'd love to see it, you might start a whole new conversion attitude with people preferring the cheap & easy 4AF.

Yup- Now, ":no compression" means you have measured it with a compression guage and got under 100psi I hope.. or is this just a thumb-sucking exercise??

Modify it for economy, not performance.. http://www.rollaclub.com/board/topic/42407-the-girls-ke70/ Carbs, cam, exhaust, compression..

I can't see tuning it giving you 10l/100km off your 17! What are the plugs like?? Black as a coal mine? Might be the needle/seat leaking all the time or the float sunk.. grab some different jets off guys on here and try them.

You will only find out when you do it... The further forward the motor is, the less you will have to worry about the bell-housing fitting. Naturally that will make the handling worse.. I think you will have to cut the tunnel to fit the J160 in there, but not the firewall to fit the motor in.

Just bore your 4K out to take 5K flat-top pistons. Get your cam ground, buy some extractors and fit a Weber 32/36 or twin SUs. Its been done successfully and there are posts on here about it, and if you read filfredericks topic about his twincam 4K you'll see he took it out to 1600cc. http://www.rollaclub.com/board/topic/51097-4k-twin-cam/page__p__522189#entry522189

Use the J160, chop the floor... its a drift pig you'll never rego anyway. Ratios are good and close! Couple of guys in Altezzaclub race other cars with the beams in. http://z4.invisionfree.com/lexusaltezzaclub/index.php?showforum=39

How was it doing that? Don't they have a spherical end that rides along the reverse shaft? Sonds like something has broken and fallen off.

Sounds like carb as you say. I think its Dellorto's that have the chokes come loose in the body, so check that and then it will have to be a strip to check float level and dried out resin or dirt on the needle and seat..

Only if it is a leak into the manifold at #1, otherwise surely a fuel issue would affect all 4 cyls. If its twin carb then it would affect 1 & 2 cyls the same. Do what Trev says to start with and see if the misfire follows the plug or lead. The compression test should show up any valve problem, so there is not much else that can be causing it. What were the compression readings?

That's interesting- So is that running stock front suspension and stiffer, lower coils in the back with stock shocks and sways?? Understeerey would be expected if the tails now got more grip and the motor is never going to power-oversteer it, but it will be educational to add each component and feel the changes.

How did the Green Machine go?? I'm amazed that the Altezza diff head fitted the T-diff.. Toyota never change much at all.
