There is an interesting build log her for a honeycomb core race car: random research dp1 Justin

Thanks Doug. I didn't realize until now that there is indeed a sphere cutout inside the uprights. I will use that as my pivot point from here on out. I appreciate your willingness to share these models. They have definitely been very helpful. I will measure and compare my C5 uprights to them and...

Well I'm running the longer stroke version of this engine, so I likely won't make power much past 8k. The stroke will be 95.5mm = 3.76". This is fine with me as the hydraulic lifters in these heads don't much like being rev'd any higher then that. I can build up a shorter stroke version to rev...

I've had a bit of change on the engine I plan on using. I have a Audi 2.5L 20v engine that I was building for a car a while back. The project never was finished, but I have most of the hard parts already. I've decided I will finish up this motor, and use it for this project. I recently purchased...

I didn't do the modeling on the Uprights. Your best bet would be to contact Doug Clark on here for the models. Regards, Justin

Yeah, it looks to be a pain. For my street tires I'm going to run 18" wheels so those aren't a worry. For my track wheels i'm going to have to work on getting the correct ID for clearance. PITA, but I've already purchased the uprights. I've been doing some cad modeling of the C5 upright. Trying...

Terry, I found this on CCW's website regarding their 16" wheel install for the C5 vettes:

Terry, I haven't tested 16's on the C5 uprights. It is common for the Corvette guys to run the CCW Drag package that runs 16" wheels. From my models of the C5 upright, there isn't much room there. The minimum inside diameter with these uprights is ~15.75". Definitely minimal room. I'm looking...

BTW, Here is me and my assistant pondering this build.

Thanks for the heads up. I've just been reading of datsun guys of getting good takeoffs FA slicks. I've never actually ordered a used set. Anyway, The slicks I'm looking at are as follows (Hoosiers): Front: 43660 23.5 X 12.0R-16 Rear: 43676 25.5 X 14.0R-16 It is very important to me to run a...

I've been trying to determine what I want to do about wheels/tires and brakes for this project. From my research, I can run as small as 16" diameter wheels with C5 uprights. Smaller than 16", and I'd need to run a drop spindle for a C5, which cost over $1000/corner. I would like to run used race...

I've been thinking more regarding my backbone design. It seems by having a direct connection between my front and rear suspension, I am creating a very direct load path through the chassis. I don't find many chassis designed like I'm proposing. This isn't very confidence inspiring :) It would...

The front and rear sections are very pliminary at this point. I will be adding more triangulation there once I get the differential, engine and trans modeled. I do plan on trying ORP at some point. Justin

I'm all ears on ways to make the chassis more rigid. What I don't want to do with the the chassis is have a petty bar, or any other bars that run through the passenger compartment in that manner. I don't have room to triangulate the door bars in the lateral direction. Also, I'm not planning on...

I plan to have all of the 1.25" tubing laser cut so I don't have to deal with the notching. I agree that would be painful!!! http://www.frasersteel.com/notches.htm http://www.youtube.com/watch?v=UeGVbtrrHjE Regards, Justin

My feeling on this is that you can't triangulate the outer tubes as well to stabilize them like I can do with my central backbone. The efficiency of my backbone per unit mass I believe will be greater than if I took care of my torsional loads externally instead. I would like to play with FEA a...

Playing in CAD more. Looks like I'm extending the wheel base to around 95" from the factory 90.7". Doug Clark was gracious enough to share his models for the C5 uprights, hubs, and rotors. This has saved me a ton of modeling time! Thanks Again! Next on my list is to rough out the transmission...

Here are some dimensions on the factory 240z-280z. The car with the widebody kit is ~ 72" wide now.

Thanks for the reply! The widebody kit is made by Reaction Research: http://www.reactionresearch.com/280yzgallery.html The 2JZ definitely can be peaky. I plan on a fairly modest build for the engine. i will be using a stock lexus SC300 engine for my build. This is the non turbo version of...

Hey, I just found this site, and it really blows me away the quality of the information and builds on this site. I had to sign up so that I can learn and hopefully contribute to others. Regards, Justin
