I want to change my stock SU setup to a more reliable solution for endurance racing. At first I was considering triple webers, then realized the ITB availability. I have looked at the options below and cannot find much info on others experiences with these products and suppliers, or if it's worth the expense. Should I choose the Megasquirt MS3-Pro or some other system to compliment this setup? Engine is an N42 L24 block but I think I may find it is bored out once I get the head off. Attempting to decipher the CAM numbers it references a 420-02 Cam tech grind CWC camshaft.. The tach in the car has a redline mark at 7000 RPM so maybe I have something decent here? If I find this is a 2.4 stock block, I have a rebuilt F54/P90 flat top I could use and just transfer the head/cam to this engine. Looking for experts on this. I am good at teardown and rebuild but no engineer. Thanks in advance for the help. 1.

Forgot the 69.

Looks like I barely missed having a 69 series 1.

Too funny......

NICE!! Keep them alive and running...........Is that crankshaft planned weight distribution?

Me either but R&D isn't cheap anymore, yet I understand your position. I have money to spend its just do I spend it just to have better wheel choices?

I have the Futofab rear axle CV conversion kit. http://www.futofab.com/index.php?option=com_content&view=article&id=175:datsun-wcr-cv-axle-kits&catid=38:datsun-drivetrain&Itemid=122

I haven't but I already purchased a front/rear set of BC Racing coilovers that I cant use with anything other than the Datsun components. I have an R200 rear with a Quaife LSD and just wanted a better wheel choice. Not pushing the HP you are. This is an endurance race car with about 250HP at the crank.

Are these still available or did they not make it to the shelf? I will buy a set today.

Thanks for the info tim.d. Looks like you and I will be the guinea pigs on this one. I should have them mocked up in a week and will post pics but will not be able to test until the end of July. that is if I meet my deadline on the build before the race at MSR.

I realize this is beating a dead horse but just checking to see if anyone has been successful at this with available stock auto parts. I know most everyone has the front 5 lug hub for about $400.00 but the only one I found that has the rear is Arizona Z. I talked to Dave today and he said the front/rear set is $2200.00. Dave makes some great stuff but I am looking for a less expensive way to have better wide wheel choices. I just found this and am checking now on availablilty. Thanks in advance for the help.......

Thanks. I figure buy what will last or you will buy it twice at more cost. In fact I did order those from Dave at Arizona Z, just forgot to put them on the list. 2 - Adjustable Billet Outer Tie Rod Ends $69.00 EA.

Thanks for the info........enjoy.

Very nice. Looking forward to your review as I am sure everyone else is as well.

Cool, thanks. What set did you buy?

Thanks for the insight. I appreciate it.

I have a headache looking for 10" wide wheels for racing my 240Z. I used XXR 527 16X8.25 0 offset with 245/45/16 tires on the old race car. The RE-11 or any decent track tires stopped making that size. I am considering going with 17" wheels since the track tire selection is greater. I have heard great things about the VENTUS R-S4 and it comes in 255/40ZR17 which fits the 10" wheels. Volk wheels are the only ones I have found that can be made with a custom offset in 114.3X4 at 17X10 and up but they are 700+ bucks ea. I found some that seem to be Meister Work knock offs on Fleabay http://r.ebay.com/Vs7yDu but not sure they would hold up. With the +10 offset would it be advisable to use the 114.3X4 to 100X4 one inch adapters. They can't be much better than the XXR wheels and they lasted many races in the old car and only cost $85ea. Any opinions and/or help would be greatly appreciated. Thanks in advance........

I hear you, not sure about 70's engineering minds. Putting it back to preserve the way it was and also using it as a framework for the full belly pan.

The reference to "an actual race car" is a little cloudy. It was an actual SCCA race car in the 70's with that suspension technology. I had a 1973 240Z that had Ground Control coilovers and it faired well in endurance racing so I expect the BC technology surpasses that and should be fine for what I am doing. Already pulled the trigger and will keep everyone informed. Thanks for all the replies.

Thanks seattlejexter, I heard bad things about the OBX, made in China, knock off, etc. MFactory is a grand. http://www.teammfactory.com/catalog/partno/MF-TRS-05R200 I just picked up an 81 turbo r200 diff for $280.00 and planned to purchase a Futofab WCR CV Axle Kit for $900.00 so I guess another grand and its all done for the price of what Whitehead is suggesting.

Thanks for the info. So weld it and call it a day? I can't see spending 2K on a Quaife equipped 3.54 R200 LSD diff . i have a newly rebuilt Quaife equipped 3.54 R200 LSD diff here right now that is ready to go out. $2000 Otherwise i may have a used clutch type lsd unit to put into an open 3.54 r200 diff here. and that would be same price as listed on the site. I have a 3.54 R200 LSD diff waiting to be shipped to me on the next container. I can air ship it over for an extra $250 Thanks, Mike Hanson Manager, Whitehead Performance
