Just wanted to wish everyone a Merry Christmas and Happy New Year!!! This will be a good year for me thats for sure, I will have my hybrid ZX done by the end of spring and on the road for summer! I can't wait! Thanks for all the help the last few months! Guy

So I want to get the full 7/16" ARP studs then, right! Thanks, Guy

What is the stock stud size? Also are the studs screw in? I am having my heads ported and polished right now so I can't look at them. The guy (Jeff Ondo of www.ondoperformance.com) building my heads is going to install springs and all that so I am not worried about that since I told him what I was doing to my engine. Oh yeah and what hyrailic roller lifters would you recommend? Thanks, Guy

Ok I am starting to get together all of the engine parts that I will need to complete my engine rebuild of my 93' LT1. What I want to know is what do I need to be able to use non-self aligning roller rockers in a 1.6 ratio? I am going to use the LT4 "Hotcam" and hyraulic roller lifts. Also what size of push rod should I use? I am new to the engine rebuilding thing and would appreciate any help! Thanks again, Guy

Yeah I am still in the process of finishing up my site. I just hope that it will help some ZX'ers in the future. As for the header, I am on my way back out to the garage right now to do the final touch ups on it. Then I will be looking for someone in the area to make it for me. I just hope that it doesnt cost an arm and a leg to get it made! Does anybody have a guess at what this might cost??? Thanks, Guy

Yeah I haven't looked into a place that can make it for me yet. I have pics of it though. Try my new website... www.datsun-280zx-lt1.com Guy

Well I have got a good start on it. I have it routed around the gear box at the top. Now I have to get them all connected at the bottom. If anybody else tries this I would suggest finding a sold foam tubing and not using the "GOOD STUFF" foam, that stuff is really sticky and makes quite the mess! I tried to find some of those foam pool toys but being winter nobody has those so I had to do it this way instead. I am thinking maybe since I have an extra header that I can use I will get 2 of these custom headers made and sell the other one with the custom one as a set for someone else! Let me know if anybody is interested. I think I will be finishing it tonight. Guy

Well I think it's done! I just have to wait for the cauk and glue to dry. Then once it's all hardend up I will put it back on and "fine" tune it. Where can I post some pics? Thanks, Guy

Ok heres the deal... I have a R180 with 3.545 gears I am putting in an 82' R200 with 3.545 gears and doing the CV swap too The reason for the swap is because I am using a 93' LT1 and I building up to about 400-450HP so I figure the R180 wont hold that for too long before it goes. Thanks for all the help! Guy

Well I am going to start to make my driver side header out of foam and coat hangers tonight. Incase you have no idea what I am talking about here is what I mean... I am going to take 1/2 copper piping insulation (actual diameter is about 1 1/4") and fill it with "GOOD STUFF" foam insulation and 2 coat hanger wires all the way down. Then I am going to make a flange for the head and mount 4 equal lengths of this foam header pips on it in the correct spots and bend and shape them so that they clear the steering gear box. I figure once I am done I will send it out to someone (need help on locating a shop that can make headers) who can make this header for me! How much should I expect to pay for 1 custom header? Including to have it thermal coated(Jet Hot) in a chrome finish? Thanks, Guy

Oh yeah what holds these in the differental? Should I ask for any hardware with this? Thanks again! Guy

Ok, I think I have located a set of CV Joints, set of stub axles, and a set of companion flanges for about $110+ shipping. Good Deal! This is all I should need huh? Thanks for all the help! Guy

Hey now take it easy on the non-skilled-fabrication-guys!(is that a legitimet word? ) j/k Yeah I bought that kit from MSA. If you need just the tranny mount I have it and I dont plan on using it since I am using a T56 transmission. $20 and its yours! Guy

So will the halfshafts work or not? Or should I start looking for some halfshafts from an R200? Thanks, Guy

Opps sorry mine current differential is an R180 with 3.545 gears. So does that change anything? Thanks, Guy

I just got a R200 from a 82 ZXT with 3.545 gears in it. I have a R180 with 3.9 gears in my 80' ZX right now. What I want to know is do the halfshafts fit and if so how? Cause my R180 has a plate of some sort on the differental that holds in the half shafts the R200 doesn't...so how do they stay in???? Thanks a lot! Guy

Yeah I'm a moron! I saw 39:11 and automatically thought 3.90. Then about 2 hours later I did the math and realized it was 3.545. Thanks anyways! Guy

Oh yeah and if this is an R200 (supposedly 82 ZXT) will my half shafts fit in the R200 from my R180 (80' ZX)??? Thanks again! Guy

I would think that it is 200mm right? I bought a R200 from a guy in texas and I think that he sent me a R180. Well first of all he said it was a 3.54:1 ratio and its really a 3.9:1 ratio!! That really makes me mad!!! I think that the 3.9 might be to low of a gear for the my 93 T56 with the .62:1 6th gear. What do you guys think, is it to low? Thanks

Well I asked my auto instructor(fox valley techniacal college) at school today... I told him the problem and he seems to think that because it has sat for so long (about a year) with out any movement that the thrust bearing might have rusted tight or something. So I guess I will see when I take it apart. Thanks, Guy

Ok incase you dont know... I am putting a 93' LT1 and T56 in my 1980 280ZX. Here's the problem... I mounted the master cylinder inside of the wheelwell so that it would come in the car in the right spot. I am using the master cylinder and slave cylinder assembly from the camaro set up. However I have modified the bracket to mount it in my car. The problem is that I can't get the pedal to go down...I mounted the slave cylinder to the T56 and it wont budge??? I can't figure it out. Isnt this assembly a sealed unit? So how could I mess it up? Thanks, Guy

I'm going to need a picture. I'm not sure what you mean. Where is this piece going? Thanks, Guy

I asked my auto instructor today about this and he said that this isn't a good idea because it will change the toe-out on turns ratio. So I guess I will just have to get a custom header or a rear dump manifold that only sticks out about 2" from the block. How much should I expect to pay for a custom header with a thermal coating? Thanks, Guy

I was thinking maybe if I noched the drivers side frame rail about 3/4" to move the power steering gearbox over about 3/4" and bang on the inside fender wall so that it would move over a 3/4" than my header will work. Then after I noched it I was going to weld everything back in and renforce the frame rail with some 1/4" flatstock on the top, bottom and outiside. I know this might change the geometry of the steering but all it should effect is how far the wheel goes one way or the other...right? So I would need to adjust my toe so that my steering wheel is straight. Let me know if you guys think this is a good idea or if I should just get a custom header. Oh by the way this is for a LT1 Thanks! Guy

Yeah about the cam that's kinda what I thought, I thought it might be more of a PITA that its worth right now. The guy that is port and polishing my heads is also putting in the new valves and springs. So I am just going to be buying the HOTCAM and not the whole kit. About the headers, intake, and optispark. I have headers, I am going to run some kinda of custom cold air intake, and I have the new opti spark and timing cover so that is all covered. I guess I should have mentioned that before. Thanks for all the help guys! Guy
