George, That's my '84 PNV as it was purchased in 2002

Hi All, I have '81 ECU & AFM, yet the crank angle sensor is in the distributor as in the '83/4. Can I use this AFM/ECU combination with the late model distributor, or do I need to invest in the '83/4 items? Cheers, Dennis

As a spin off from Dave's thread, I have found, so far, three (3) different oil pumps in L28ET engines. For example: The cast marks on the side of the pump housings say H3, H33, and H4. New line, maybe K4 as suggested. The H4 I'm told, comes from an AUTO with oil cooler and is reputed to be the best & highest volume pump of all. I have seen or been advised that all models have been fitted to L28ET's. Can someone tell me the difference between these pumps and not just that they have different volumes. Sorry for the bold italics, I'm not yelling at anyone, just trying to highlight the question. Cheers, Dennis

To my knowledge, it isn't the OIL PRESSURE as much as the VOLUME of oil the turbo pumps distribute. Oil pressure can be gained by packing the pressure relief valve spring with washers, but this doesn't increase the the amount of oil the pump can deliver.

The engine cost me $640.00 delivered to my door, which I thought was an absolute STEAL! It has a P90 turbo head & I acquired a standard turbo cam (thanks to one of the guys on this forum) As for the spare exhaust manifold, it's staying where it is for now, as I have to be sure the one I have is A'OK, similarly with the inlet manifold. It might pay you to stay in touch as I wont be using both of them eventually. Sent you a PM that might help SWR in Sydney can supply a high flow turbo pump for $137.00 I have an '81 L28ET AFM & ECU that I plan to use with a microtech piggy back to control the fuel & ignition etc. I'm trying to stay stockish, as much as possible, as it's all going into an HR30 Paul Newman Version Skyline Coupe, of which there is only 5 in Oz. Cheers, Dennis

KA24 pistons have a dish of only 2.80cc, but when I was looking at building a 2949cc motor, the piston of choice was the KA24, but with the lip machined off to create a flat top piston. Cheers, Dennis

There is a guy on ebay "texas????" selling what he claims to be an L28ET Oil Pump and he tells me the casting number is H-3, so I guess there must be bigger and or better when there is H-33 & H-4 pumps as well. And don't know which p/n corresponds to which casting number.

Dave, Just by chance, do you know the cast number on your existing Oil Pump? On my L20ET I have H-3 on the pump housing, on the F54 L28ET I have H-33 and I'm told the Auto L28ET with cooler is H-4. Cheers, Dennis

I stumbled across this web site the other day and maybe you might find it helpful if you can understand the translation. www.aurora.dti.ne.jp/~joinme/index.html I used altavista babelfish as a translation medium. Cheers, Dennis

Excuse me if I'm a little confused, but I guess you have these pistons in a running engine right now??? If this is the case, would the program not give you these dimensions depending on the engine configuration you have. Either L24, or L26, or L28. If you have these pistons in an L28 for example, I guess you would know if you have L28 rods & crank or not and if you have, the program gives you all that information, or at least mine does. Cheers,

VG30 BB Turbos have a stock T 03 mount flange and bolt straight up to the L28ET exhaust manifold. I'm going thru the same exercise now and I'll try posting some pics of it mounted up. If your in Oz it might be easier to send em to you direct. Cheers, Dennis

If your thinking of going down the L31 stroker path, maybe you should have a rethink. I was going to do the same until I found getting an LD28 crank was a AU$1000.00 + exercise. I can put you in touch with 2 people that have them in Oz, but they want over a grand for them each, but just getting your hands on the crank is just the beginning. There is a fair bit of machining to be done to make it a good high revving crank and I don't think it's value, as the big gain is only torque. I scrapped my L31ET aspirations for an L28ET + 0.040 o/size because I will acheive the HP I want and the percentage gain in torque Vs dollars wasn't worth it. Cheers, Dennis

MR30 Skyline derivatives (maxima maybe) that went to South Africa and NZ.

HAS EVERYONE TOTALLY IGNORED THIS COMMENT?????????????? Here in Ozland, they modify an L Series front housing to accept the late model 92/93 RB20DET box and have a lot of success with it. I have a front housing away getting done now by SWR in Sydney NSW Australia and from what I can find out, it's primarily a machining task to make clearance for the much larger front bearing. I'm told the Zed rally guys use this modification with great success and they're getting 300+ rwhp. Cheers, Dennis in Oz

Another quick question on the same subject if I can. Can the red 20 tooth gear & spindle be purchased in the USA on their own, as in Oz we can only buy the complete speedo drive assembly and the 20 tooth was only available for a 4 cylinder and is a different assembly. Will take a couple of pics and try to get them on the forum so you all understand what I mean. Cheers, Dennis in Oz

Sorry, saw these pics, but took it in a different perspective. I haven't taken mine off the manifold yet, so I wasn't considering them from this view. Thanks.

I have a P90 head, that is complete, but the cam towers have been removed prior to me getting it. How can I establish their correct sequence for assembly, or doesn't it matter all that much. Cheers, Dennis in Oz

Nope! Nothing like what I have. How do I get pics onto this site from my PC? I will take pics tomorrow and show them If you tell me how. TonyD, if I email my pics to you can you get them on here. Thanks.

Sorry! maybe I should have put the ECU piggyback comment in another thread or equally on another forum. Dave, I thought you were an intelligent being. Maybe you should join the likes on SAU cause they show similar intelligence. You take this out of context ....... I guess your a woman!

Have searched ALL 20 pages and found nothing. Thanks heaps.

I am currently building a replacement engine for my Skyline. It now has an L20ET on board. My new engine is an F54 block, P90 head, stock L28ET cam (thanks to another member of this forum) 1.0mm oversize L28 Flat Top Pistons, L28 rods & crank. It will have about 8.7:1 compression, 460cc injectors, will be boosted by a VG30 BB Turbo and I'm looking for similar HP and expect it with less than 1 Bar of boost, running on 100 octane ULP fuel. ECU is going to be stock except for Microtech piggy back to control the fuel & boost issues. The engine guru's in this country say it's the only way to go. My only question is re TB size.
