Wiring ECu's Hi Cobber, Yes it looks like yours is a 1990 LS 400 as it looks just like one of the ECus I've got which is from a 1990 LS400 over here. I see that you are missing the 4th plug also, so as it seems to be important I'll get if from a Lexus breaker over here. I'm running the...

Wiring Issues. Hi Macro, The engines and boxes came from UK reg'd, specification and supplied LS400's, so getting the ages and market specs isnt a problem. I have tried to correlate the wiring codes and the pins off each ECu without success, there are 15 wires in one and 17 wires in the...

I've got quite a few relatives in Sydney, who we visit every couple of years, one of whom's a lawyer. Thanks to the Lebanese propensity to indulge in criminal activity he's bought himself a very nice, very large apartment very close to Darling Harbour and no doubt is even now rubbing his...

Guys, As some of you may know I'm building two Cobra replicas with LS400's providing engines and gearboxes. Having equipped myself with the excellent wiring diagrams available through this site and buoyed up by the sage advice and encouragement of Lextreme members I went forth into the...

LS 400 engine and gearbox transplant wiring info req'd I'm just wiring up the first of the LS400 engines into my Cobra replica and am wondering if there is an simple guide available for wiring up the the combined ECU and ECT used on the LS400. The information on the Crown is very useful...

So how does anyone go about testing for trapped metal particles inside a secondhand oil cooler? Cheers, Tony

I would be very wary of buying a secondhand oil cooler without having full knowledge of its history............you never know what detritus could be lodged within those nooks and crannies in the oil cooler , perhaps following an engine breakdown, just waiting to re-enter the oil flow and buggar...

As I have mentioned before the UK spec LS400's have a factory fitted water cooler jacket fitted into the oil filter housing. This ensures that the oil and water are at the same temperature. Cheers, Tony

I'm getting a bit confused here. I too had heard that you can run standard ECU and injectors up to 8 psi. The ECU I was led to believe was as self learning ECU and together with the lambda sensors would compensate for the lean mix under boost conditions by increasing fueling. With my...

When you change a cambelt you will also find that when the cam pulleys are correctly aligned with the timing marks on the front of the block the rotors should be pointing to two notches on the aluminium distributor cap housings. With a keyway and a notch to aim for these japanese engineers...

WATCH OUT..........the securing 14mm bolt in the centre of the pulley has a left hand thread !! Just had an interesting hour making the tensioner operate opposite to the way it was designed. I'm putting the power steering pump on the opposite side of the engine than normal but keeping the...

Watching the news reporter in New Orleans talking into the camera I found myself looking over his shoulder saying to the Mrs, "Just look at that Lexus, what a waste, I wonder what the engine will go for........" needless to say the withering look she gave me brought me back from car geek mode...

No wonder the pipes break...........wafer thin aluminium, three guesses what happened when I tried the weld the crack up today....... And the egr pipe on my Shogun has now also developed a crack and is blowing !! Anyway I think the answer is to replace the pipe on the 1UZFE's after somehow...

97 Octane here ( Shell Optimax) is currently selling at the equivalent of $8.53 per UK gallon, so should just be under the $8 per US gallon.......... I've got a 3 ltr petrol Shogun, a 3 ltr Jag and a 4.4 litre Cobra. The Cobra is actually the more economical car as long as I dont go too...

Guys I'm just finishing refreshing the two LS400 engines I'm putting into the Cobras and one of them has the usual crack in the bellows section of the EGR tube. I've done a search on the forum and basically there are two schools of thought, replace the tube as per normal ( I'll probably...

Guys, Do not use a rubber donut at the end of the gearbox in front of the propshaft if you are not running a support bearing on the propshaft and the diff and gearbox are not perfectly in alignement. In my BMW engined Cobra I used the rubber donut at the end of the box, connected to a...

I had the same problem with a fuel pump in the Cobra's tank, the power lead had come adrift.......I was so convinced I'd killed another fuel pump that I went and broke a cardinal rule and bought a brand new one from a proper parts emporium. Opened up the tank and the power lead was swinging...

The article looks absolutely brilliant for wiring up a crown engine with the two computers. I also think that I can use some of the information ( especially fuel pump info) when I'm wiring up my two Lexus LS400 engines into the Cobra replicas. Is there any chance of getting the same sort of...

Thanks for the info re AFM installation guys, it makes things a lot easier......love the black painted sewer pipe btw, I think I'll use the same product but paint it silver to reduce heat soak..........( and to see if I can fool anyone into thinking its aluminium). The BMW is in my Cobra...

Does the AFM have to work in one plane or can you mount it on its "side"? Space in the Cobra engine compartment will be at a premium. Also I have been told that AFM's in general benefit from having a laminar, undisturbed air flow, and require at least 8 inches of straight induction pipe prior...
