    Street Build Midengine 4G63

    My freind saw it at a shootout one year. I have been unable to find any more detail on it. I've had this idea for a while and before he showed me this I had no idea someone was already driving around my proof of concept.

    Street Build Midengine 4G63

    I swear I wrote up an entire response here the other day but I guess it didn't submit properly.Will you need to have the engine back out for any other reason? I suggest when you can get to it, set the engine at tdc and add a new timing mark on the balancer and maybe plastic weld a new pointer...

    Street Build Midengine 4G63

    I have looked at this arrangement with this idea in mind and with this specific chassis. I think the oil pan needs to be clearanced some but not as much as I initially thought it might. Obviously it has been done successfully. It would definitely need bracing with any kind of power but the...

    Street Build Midengine 4G63

    What kind of alignment or clearance issues do you see for rotating the tcase forward for a mid / awd layout like this?

    Wavetrac front differential in a w4a33

    Ok, I should preface this with two things. First I have not run this transmission since modification and I am not near it atm. Second I took lots of pictures and notes and lost all of them in a hard drive crash. While I was trying to back it up ironically. So unfortunately I only have my memory...

    Street Build Midengine 4G63

    Beat me to it. I've had a built turbo sw20 for a while and considering the availability and cost of 3s stuff and also being a dsmer with tons of 4g parts this has always been a longer term project I want to try. There are how many k20 mr2s now? I still can't believe there aren't more nasty 4g...

    Now LS swapped 3000GT, was 4Gswapped

    Awesome progress as always. I'm always glad to keep seeing progress on this build. The cage looks really nice, i'm surprised it still weighs as little as it does considering.Do you have any more pics or info on the transfer gears? I can't say I've heard of that problem before. Did you get...

    Rear diff backlash adjust question

    I just went and looked at the new billet frontline diff cover, I only ever saw his plate steel ones before. How much help do you feel the load bolts are?I have solid mounted the rear mustache brace before on my 1g, colt is very similar. I was contemplating just welding the mustache brace into...

    Rear diff backlash adjust question

    Thanks allot for the response, you've always been a terrific source of good tech info. I know maybe allot of people would rather just pay to have the work done that requires the level of knowledge and detail you just described but for those who can and do use this information on their behalf I...

    awd auto tink and shudder when warm

    Had a similar experience and it was a u joint on the driveshaft. Did you check for tightness with it jacked up, e brake off with everything loose so the wheels can turn?That said, it wouldn't really cause a shudder, that sound more like the transmission. How is the fluid level and color? Even...

    Rear diff backlash adjust question

    Tim, do you have any opinions or input on the setup of the actual lsd internals of the evo diff? I just did this all myself recently and I'm wondering if you shim the clutch pack at all or measure or modify break away torque? Many other rwd based platforms discuss the setup of the salisbury in...

    Now LS swapped 3000GT, was 4Gswapped

    I love the first pic. I drove my talon around for about 3 months with no bumper or crash bar without being pulled over, I suppose a front mount provides some kind of impact absorption right? How's it running with the new setup? Driving - tuning it yet?

    Dammit I apologize if I am sidetracking this thread from this awesome car. I do have a few more things to say that are specifically relevant to this swap and the work you have done though.If you would like to move this axle / diff tech stuff to a different thread so as not to detract from your...

    Now LS swapped 3000GT, was 4Gswapped

    I apologize for not being more knowledgable on the 3s awd stuff. It sort of wasn't relative to my specific interests when I was researching and comparing junkyard stuff. I'm not sure what 18 spline refers to. It is my understanding that all the 3s stuff went to the big 27 spline inner after 92...

    Now LS swapped 3000GT, was 4Gswapped

    Okay, so upon reading that I realize it's a little hard to understand everything thats going on there.Bastarddsm, I am suggesting you try a 92+ 3s intermediate shaft with a dsm awd driver axle and a dsm 2g fwd turbo passenger axle. If it seems to work I can maybe make you a carrier bearing...

    Holy crap this is awesome. I have allot of questions and comments here but first I may have some useful axle info to add. Let me preface this first by explaining a little about what I am working on and have been doing lately. I have a 90 colt vista I am doing a dohc swap on atm. It is a sohc...

    1G 1989 Colt 4wd wagon - what am I getting myself into?

    That's what you get for living out in Ohio I guess. Haha, I'm joking of course but I could definitely have it straightened in a day here though. I like it, I almost wish that was the type I had purchased, it's a bolt in swap for the dsm transmissions and already built with a live axle.The km...

    1G 1989 Colt 4wd wagon - what am I getting myself into?

    Is it the twin stick transfer? Sounds like it was a real truck style 4wd setup. That's pretty cool, I've never seen one of those.

    1G 1989 Colt 4wd wagon - what am I getting myself into?

    I dunno if there is anyone near you that can do it but there are special machines that can fix very bent rims. I had a nice alunium rim my gf drove under a guard rail. A local shop fixed it perfectly for $40. That's if you can't easily find a replacement.Just out of sheer curiosity do you...

    1G 1989 Colt 4wd wagon - what am I getting myself into?

    Ya I feel ya. I was trying to source valve stem seals at a mitsu dealership that I couldn't find at local part stores and the parts counter guy basically accused me of making the car up. I know it's technically a plymouth but it says imported for plymouth right on it, it's all mitsu parts. I...

    1G 1989 Colt 4wd wagon - what am I getting myself into?

    Congrats on getting it running well. I just recently got a 90 vista awd 5spd myself. It's the sohc 4g63 though with a funky km182 transmission.Mine was smoking really badly when i got it too, I ended up pulling it all apart like 3 days after I bought it and did a mild rebuild/ rehone and...

    help getting rear sub frame bolt out

    I'm not to familiar with the 2g rear subframe bolts but something similar happen to my 1g. The nut was severely rusted and I usually crank until they snap off because you are replacing the bolt at that point regardless once it's all apart.Well more force resulted in the top part ripping...

    RWD 4G63 Subframe mod?

    No, not heated, at least I'm not. Everyone's got their relative perspectives on life, it's this hazy middle part where we gotta figure how to interact with each other coming together from all different angles where it gets interesting. No use in gettin miffed over it.You are correct that I...

    Wavetrac front differential in a w4a33

    RWD 4G63 Subframe mod?

    I don't understand, is that the link you intended? I don't even see where I used the word alot? I will admit I probably do use it and I didn't realize it's not actually a word though.There's another funny philosophical semantics thing I always enjoyed about grammar.Word - Definition and...

    RWD 4G63 Subframe mod?

    Well by balance I meant safety concern vs getting shit done. I didn't really explain that well, not like f/r balance. Although the stock dsm weight distribution is so terrible I can't imagine you could make it worse. It has allot to do with where you put the weight, you can set the thing pretty...

    Project 2G RWD conversion

    Oh man, I haven't kept up on this forum for a long time. This is my first seeing this project. You definitely need to put up more pics. What turbo setup are you planning? What kind of power/et are you shooting for? Sorry I'm not sure what the stock chassis record is.I love the fabrications...

    I know he sold the big block. I also know they are not hard to find or expensive. There are tons of lincolns and trucks floating around no one wants anymore. I daily drove an old lincoln for a long time, the gas mileage is just a killer. There's nothing really wrong with them, they are just...

    RWD 4G63 Subframe mod?

    Ok I just read this whole thread. I originally liked the idea because my first love is the 460 ford. I was working on these long before the 4g. Honestly I still would like to go back and use my turbo/efi knowledge to hot rod one dsm style. The main thing about those engines is that they are very...

    Can you change/upgrade the final drive ratio

    Tranny gear ratios for DSMsIf you could find the parts from a ggsx, mitsu did make the gear sets you are looking for so it does exist. Those would give you a 3.937 final drive.The other problem is the difference in the transfer case ratio between the 1g and 2g. If you got the matching...

    broken fron subframe studs

    If you can cut and drill and weld you can always fix stuff made of steel. 2 bolts aren't worth a whole car. The simplest thing you can do is drill it out. Depending on how it broke that may or may not work though. First grind the bolt piece sticking out flat so you can drill it straight. Next...

    My compound turbo set-up

    I didn't mean to say you were running low boost. I just meant specifically how you were talking about the compressor efficiency of your 75mm relative to the PR others run them at to achieve higher mass flow. I meant what if you leave the secondary at it's current PR and up the primary?Just...

    My compound turbo set-up

    This sounds extremely interesting and very similar to what I was contemplating. I can't wait to see your build thread and some pics of the layout.Do you have any plans for primary stage intercooling at all?How does the area of the t6 inlet compare to a 3" pipe?Overall it sounds...

    My compound turbo set-up

    Yes you are absolutely right, I was even thinking about you while I was writing that and thinking I hope he realizes I was focusing more on Paul's setup and not your own.I think maybe because your's is a race application people think a crazy setup makes more sense and the complexity and all...

    Compound Turbo Setup Holset style

    Pure awesome. This is exactly the kind of thing I was thinking about with the holset turbos and compounding proving themselves lately. A perfect marriage. I think this really captures the dsm spirit, creativity, ingenuity, low cost and very fast.I asked this the other day in Paul's compound...

    My compound turbo set-up

    Cool to see I'm not totally out in left field with that idea and the two of you have also thought about trying it as well. Or maybe all of us are out in left field together. Either way I think I'm in good company. Usually I say stuff like this and people go, "oh, I get it, you're crazy".I...

    My compound turbo set-up

    After seeing some really nice remote mount setups and how much they don't affect the engine bay setup that route really made allot of sense to me for compounding.Leave the stock location turbo as is and optimize it as you normally would, then run the exhaust to a big remote mount in the...

    I need a different muffler, but what???

    To answer more specifically I would try this;You say the fireball muffler is smaller than the others you suggest, I would try and put this up front where the cat was if it will fit into the new 2 1/2 system you are going to build to join the header to the rest of your 2 1/2" exhaust.This...

    I need a different muffler, but what???

    There a few basic rules I've learned from my experiments with exhaust systems.The more volume of muffler you've got the quieter it will be, given the same style of muffler used. Ie, absorption vs chambered, comparing like with like.If a straight through absorption type muffler is big...

    AWD Rear Suspension Idea

    I do see how it could be misleading, it's a relatively complicated aspect of a relatively obscure suspension function. If anyone reading this thread cares to know or discuss more about the specifics it is not a bad idea to really point out the differences.You are 100% right again and I do...

    AWD Rear Suspension Idea

    You are right about this, in retrospect using antidive to try and illustrate my point made no sense and is only going to muddle this further.Yes and no. Yes inboard vs outboard brakes do change the effect on how the torque reaction is transferred to the chassis. Just the same as live axle vs...

    AWD Rear Suspension Idea

    Are you so sure?So how does antidive work on the braking system on the front of the car? Most cars have had independent front suspension for quite a while and this still seems to be an issue engineers spend a bit of time taking into consideration.The torque reaction at the wheel is...

    AWD Rear Suspension Idea

    It's funny I've got 2 sitting in my back yard right now. That was actually my first thought. But I would also like to try road racing this thing and I figured I would give the independent suspension a shot first.Plus that is allot more bs to do because honestly, why would you fab a new rear...

    AWD Rear Suspension Idea

    It is not so much the shape of the trailing arm as I believe you are thinking of it, but how it attaches to the chassis and that point in relation to what is called the antisquat line.There is a torque reaction to a powered wheel that is equal and opposite to its input, some of it is...

    AWD Rear Suspension Idea

    Dang, I am impressed you found that. I have been posting on my local dsm forum about these ideas for a little while now it's true.I didn't have enough tech posts to put that up or link to it before when I wrote it up.The specific corvette style mod is only a smaller piece of that...
