350DreamN Posted December 23, 2002 Share Posted December 23, 2002 I guess I should address this to Mr. Greimann but I would appreciate any input. I've been reading up on the driver side exhaust problem and I'm wondering how yours is set up. Thanks, Bob Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted December 23, 2002 Share Posted December 23, 2002 I have the steering box style system and am using Chevy manifold #364747.They are fund on late 70's GM cars. It is the only bolt up solution. If you have rack and pinion, the fit problems are different. There is a picture around here somewhere.... oh, here it is: http://home.earthlink.net/~dvgreimann/largeimages/leftmanifold.jpg Quote Link to comment Share on other sites More sharing options...
350DreamN Posted December 23, 2002 Author Share Posted December 23, 2002 Ouch that looks tight. Please clarify for me. "Box style" - does that mean recirculating ball type steering? I believe that's what mine is(it's in storage right now and can't compare the two). Also is your engine offset per JTR and is your passenger side similar to the driver side? Thank you, Bob Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted December 23, 2002 Share Posted December 23, 2002 Yea, recirculating ball. Box is easier to type! The right side is a rams horn. There is pleanty of room. The ZX can't take the JTR setback. With the motor mounts directly on the crossmember, the distributor is about 1" from the firewall. There should be some discriptive pictures at my web site. There is a link in my signature below. Quote Link to comment Share on other sites More sharing options...
350DreamN Posted December 24, 2002 Author Share Posted December 24, 2002 Power is always a priority when thinking about a swap like this(300+hp vs 150hp). But I do aim to build for future power increases. My main concern at the moment is to prepare the front of the car for best performance which would dictate the need for headers. If you know of headers that will work with a manual r&p steering then I'll start scrounging the yards here to find the parts I need. How heavy is the steering with a manual r&p?

Modern Motorsports Ltd Posted December 24, 2002 Share Posted December 24, 2002 I don't have much of a comparison on the 'heaviness' of my steering at present. It's certainly lighter since I relocated my batter mid-car (toolwell behind pass. seat) and stepped to the aluminum heads. Previously I had problems with parking downtown (albeit I was only a few weeks out from a bone marrow transplant and a fly could've kicked my ass!). I'm intending to use a Hooker common 1-5/8's header with some wedges at the head/header interface to rotate the collector outside the steering flange. My present 'cheapie' headers we custom bent years back to clear and they no longer match my heads nor suit my most recent V8build. Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted December 24, 2002 Share Posted December 24, 2002 350DreamN, you'll want to decide and commit to your power goals and driving style (ie. hp/tq and manual or power steering) now if you haven't already. Header choices (manifold type/header type/size/fitment) go a long ways to defining your power limits if you're looking quite lofty for power. Mild to mid motors it's not such a big deal......just noting it as I'm about to go to my 3rd exhaust setup (only 2nd set of headers though ) and would have preferred to have had only the one setup..........rack'n'pinion opens up more typical header options I believe.....I'm not sure how restrictive a power R&P setup is for header fitments as it's been some time since I've seen one. It can be a lot easier to change steering up front to get the ideal exhaust rather than leave steering and jump thru hoops on exhaust (you'll likely be jumping hoops either way but some hoops aren't on fire ). I've got some pics of some wedges I sent Guy that I made to rotate my header/collector flange towards my inner fender off of the steering arm (for a manual R&P setup/not box style recirc). It's great to see more and more 280ZX's being modified lately! Seems to be a nice swing in their revival. Quote Link to comment Share on other sites More sharing options...
350DreamN Posted December 24, 2002 Author Share Posted December 24, 2002 Ross, I'd like to see those wedges you're talking about. Sounds like the answer for all of us 280ZX owners. My aim for this project in the short term is to get my 300horse 350 and 700R4 in and get the car back on the road then look into performance increases after sorting the car out.

Guest Anonymous Posted December 24, 2002 Share Posted December 24, 2002 Ross C. Could you or anyone with pics of the "wedges" post them? Thanx Quote Link to comment Share on other sites More sharing options...
350DreamN Posted December 25, 2002 Author Share Posted December 25, 2002 Hey Ross, What did your old headers fit(heads) and are they in good condition? Maybe you'd like to sell them? My engine, at least temporarily, has 70's 993 heads that have been milled. Thanks, Bob Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted December 25, 2002 Share Posted December 25, 2002 Drop me a personal email rossc@shaw.ca and I'll send the wedge pics to you. The headers (present/old ones) fit OEM round port 882 (400) style heads fine. They are cheap headers that got me going and have lasted some 6 or 7 years, they're in fine shape but I did have the main flange sliced b/t 1-3 and 5-7 and then 3-5 welded together at the tubes as well, shortly after I got them to minimize flange distortion and aid gasket sealing so they're no show winner. They were ceramic coated years back and no real rust on them anywhere, just dull grey basically from a lean spell 4 years back. I can send pics of them as well/ahh, here's two pics, I wouldn't ask much at all for them, just be nice to see them help someone out. The Y pipe has heavy duty flanges on it and just needs one sharp bend smoothed out to be a MUCH better piece (one 90 degree T junction!).
