you know what i noticed Jim?
that the lower control arm and steering tie rods aren't parallel in the diagrams posted by Wanklin. Perhaps your understanding of how bumpsteer occurs is a little different from ours? https://www.rx7club.com/other-engine-conversions-non-v-8-118/2jz-gte-swap-into-fd-654918/page3/ i really didn't want to point this out, cuz i really rather not participate in another one of your debates. but i hate seeing every 2JZ related swap threads gettting ruined, turning into another useless bumpsteer debating thread. I'm not trying to tick you off or anything Jim, please don't take this the wrong way. I just think that it'd be nice if for once, we can let the thread starter do his thing, post his pictures, and claim whatever he likes (in this case, the steering rack has not been moved). Us readers should be smart enough to judge for ourselves whether to believe him or not. I appologize about our first encounter in the thread posted above, got off on the wrong foot. I don't mind having nice, technical discussions with you about bumpsteer or whatever it may be. However I was just a little ticked off when you, without even making an effort to explain yourself, completed dismissed my post with a "Wrong." Howi |

so what kind of signal is that of the speedo and tach from the 2jz and from the rx7

No, the hood has not be modded whatsoever. Yes, the steering rack has been lowered. It's an issue I'm currently working on, and the goal is to eventually completely leave the rack in the stock position. If I ever achieve this I can let you guys know how I did it. I'm sorry but for the moment, I will not provide any additional information on the project until I got everything sorted out. For Jim, I'd really appreciate it if you could try to give others a chance to explain themselves before you assume everyone's an unexperienced retard and start decrediting them. I know you're a smart guy Jim. You might want to try to start acting like one. Howi |
I tried to be courteous and civil with you Jim, but you've stripped the privilege away from yourself. I will not back off anymore.

The imaginary point is not supposed to line up to anything Jim. As matter of fact, the imaginary point travels as the suspension arms move up and down. Follow my CAD drawing below. 3. I wasn't referring to that picture, I was referring to the first, top left drawing, as you were. Noticed the note "Alternate Tie Rod Location."

Due to the nature of un-equal lengthed control arms, it's difficult to visualize the movement of our suspension system. To avoid using MS Paint so Jim won't bitch at me, I'm using Catia with parametric constraints to illustrate this: https://img529.imageshack.us/img529/8853/bump1yw0.jpg The dimensions for the suspension geometry in the illustration above are made up. All of the dimensions are constraints, which means they can not change. For example, the lower control arm has a contraint of 300mm, because the length of the lower control arm can not change. As mentioned before, the upper and lower control arms must meet at an imaginary point. To set up your steering geometry so you'll have no bumpsteer whatsoever, you must line up the angle of your steering rod to the same imginary poing. When you do, below is what happens when the suspension travels: https://img529.imageshack.us/img529/6609/bump2ly2.jpg Notice the imaginary point travels with the movement of the upper/lower arms and steering tie rod. Alos note the angle between the hub and the verticle line increased from 1.456 degrees to 7.781 degrees (this is why double wishbone is superior to struts). Using geometry, you can find the appropriate length of the steering tie rod so that you'll have zero bumpsteer. Jim, the reason why you thought the lower arm and steering tie rod have to be parallel is because they are located very closely on the FD, hence the illusion that they're parallel. Unless the steering rod and lower arm are at the EXACT elevation, length, and angle, the steering rod and lower arm CAN NOT be parallel. Howi |

BTW, Rob's example you're so impressed by is 2D geometry applied to a 3D image... not too fucking accurate, except for illustration purposes.

I expected way too much out of you Jim.

You still don't get it, do you? The point wasn't whether or not the tie rod links and lower control arms are parallel, close to parallel, or nowhere near parallel. The point is that you can't arbitrarily change the location of the steering rack and just assume that you won't have bump steer without also changing the position of the tie rod ends (and as Rob so cleverly pointed out, the length of the linkage), which is what the OP originally stated, and what I challenged. Furthermore, I don't give a flying fuck if the link is exactly parallel with the lower control arm or not. It's close enough for illustration purposes. The picture wasn't posted to be taken as a pure representation of the FD's steering geometry. It was posted to be VISUALLY COMPARED TO A PICTURE OF AN FD WITH A RELOCATED STEERING RACK, if the OP (or anyone else) had one. :rolleyes: So you wasted a bunch of time mocking up a theoretical example, apparently to prove that tie rod links and control arms are never exactly parallel (especially when using highly exaggerated angles instead of a real-world example... gee, there's a surprise) and prove me wrong. Too bad you missed the whole fucking point in your enthusiasm to be right about something. Bravo! :bigthumb: |

Try reading it again. Use your brain this time. "you're still talking about a car that you can pick up in decent condition for a couple thousand, five tops. You can't say the same for an FD, unless it has a sad history and a salvage title." you argue for the sake of pissing others off, even if it requires "adjusting" your stance on the issue of just what model of RX7 is considered a shitbox. Go talk to Jesus or whatever it is you do when you're not wasting other people's time. |

First of all, I expected that a man of your status and reputation would be man enough to acknowledge your arrogance and rudeness for assuming that I don't have the experience or knowledge with moving the steering rack on an FD. Arrogance is not only an act of self-inflating, but also the belittling of others based on faulse assumptions. Congratulations Jim you're a perfect fit. After you were obviously wrong about the following statements:

These statements shows just how ignorant and uneducated you are Jim. You obviously have never been through any formal math/physics/engineering training, otherwise you'd know that in the world of applied science, everything can be represented 2-dimensionally using simple lines, connections, and vectors. I'm pretty sure the OP was about a 2JZGTE swap in an FD. Why is it that only you're allowed to change the point to bumpsteer correction, but your're not allowing me to change the point to jimlab is wrong and doesn't understand bumpsteer? Jesus, you're easily manipulated. Do you understand that I've been jerking you around since the very first post where I told you that you were wrong? Didn't that strike you as a little odd, since you posted a textbook description of bump steer? What I was really saying was "Just shut the fuck up. I don't care." :rlaugh: :rlaugh: :rlaugh: Grow the fuck up. |
I love how you continue to dismiss the posts you were wrong about.

This has GOT to be the best post you've ever made Jim!!! You're trying to convince me, that from the very first time I posted about bumpsteer in the other thread, you purposely made a mistake about how bumpsteer works, then purposely trash talked me, just to piss me off? HAHAHAHAHA!! OH NO!! I've fallen into a great giant masterplan set up by Jim!!! LMAO!!! You fucked up. Admit it. Your arrogance told you to assume that I have no experience with the movement of steering rack. Your arrogance told you jimlab can not be wrong about bumpsteer because you must be correct 99.9% of the time. Your arrogance also told you to never be man enough to admit to your own fault. You fucked up. Howi |

everyone in here needs to calm down with the insults. and yes Jim, when I say everybody i mean mostly you.
theres nothing wrong with debating or even disagreement but when ppl are intentionally trying to piss others off with thier posts or just flat out insulting them for no reason its gone too far. so everybody, lets put the past posts in this thread behind us and just continue with a little more civility. |

If you were to look through several years worth of my posts, you'd find that I've always considered the majority of the 3rd gen. RX-7s to be shitboxes.

Go talk to Jesus or whatever it is you do when you're not wasting other people's time. I understand the pressure you put yourself under when you talk smack to the sea of dissenters, but do you really have to resort to flinging mud with me? I've been fairly straightforward with you. |
Fellas, all this arguing is really pointless. I'm actually putting a 4G63 in FD right now. Here's the simpliest solution; leave the rack where it is and cut the damn hood. I seen hood scoops on ebay for like $30, nice sleek ones too. www.grannysspeedshop.com even sells a nice K member that leaves the rack where it is. Why is everyone so scared to cut the damn hood?

question
can anybody answer this question without ripping my head off for not allready knowing?...:rlaugh: ...jk
what is the weight of the engine and trannys of each ? 13b tt- 2jz 6 spd- ls1 6 spd- i suppose retaining the 50/50 balance is going to not be possible if the swaps are to heavy right?....not enough things to take out of the front end i would think.:Wconfused i want my cake and i want to eat it too!!!...lol |
