Post up your current engine specs for all of us to enjoy.

 

I second that motion. I want to see this beast of a Tib you speak of. And no sarcasm intended.

 

Keep us posted with a build thread, sounds exciting! Also in for the current build specs

 

Are you talking about doing something like this

 

I will be doing something similar to the twin engine tib just minus the front engine.

engine specs:

port and polish job on the head
1.8l pistons and rods
garrett airsearch turbo
HKS SSQ blow off
LC-1 Wideband controller
intercooler
Tial 38mm wastegate
360cc injectors
full custom stainless exhaust
SAFC Neo
all new sensors, gaskets, bearings, water pump, oil pump, new valves, titanium springs, new valve guides and seals.
solid urethane motor mounts
custom built rear suspension with urethane bushings
full wide body kit
custom built hood
fully custom interior
all stainless steel braided brake and fuel lines
and every nut and bolt on the entire car was replaced.

I am just in the process now of building the roll cage for the rear frame. My plan once the engine is in the rear is to get rid of the SAFC neo and run a full standalone, most likely a Mega Squirt III considering I will be redoing all of the wiring anyway. I also need to replace the clutch as the one I have in now will not hold all of the ponys. I would appreciate any suggestions on that need something to hold in the range of 500hp. I have posted a couple of pics of the body and one that somewhat shows the engine. I will post more pics of the build as I go and some better ones of the engine as soon as I get a chance to take a couple. Thanks everyone for the interest and I would love to hear any suggestions as I am more or less taking it as it comes with this build. I somewhat have a basic plan for the build but will perfect things as I go. Also does anyone know if there is a LSD diff out there for the I4 tranny?

 

Sorry just realized the engine bay pic wasn't in the first post

 

Just found a better engine bay pic

 

Very clean engine bay, love the color scheme and how organized everything is. Props

I think this is a great project and would create a beast of a car, and would be one of a kind for sure. For the clutch you might have to look into a twin disk setup to hold 500 ponies, or something like a spec stage 5 or equivilant. And man for working that many hours and having a family, i'm amazed you have time to dive into modifying your tib like that!

I wish i could offer more help to your build, but your tackling a bigger pony then i have rode haha.

I'll be watching this thread closely though, you got what it takes I want to see it finished.

 

Your biggest problem is going to be rear suspension / brakes. The rest will be relatively easy. If you have any questions about the process, just shoot me a PM and I'll give you my phone number.

 

That's pretty much what Pontiac for the Fiero mid engine drive in 1984.

Took a Cavalier front wheel drive powertrain and moved it to the back, kept the same suspension and locked the spindles straight.

No reason you can't do the same with a Tib, should make a pretty good handling car.

 

This is an awesome idea... if it works you will make me very happy... I have wanted to do this but being a broke college kid do not have the money or time.... but maybe someday I can make it happen! Im rooting for you man!!!

 

That would be pretty interesting!

 

Wait wait wait... Someone posting a "long shot" thread that actually has something built and seems to have the knowledge needed to pull it off?


Am I on the correct car forum?!


This should be fairly easy for you. Just setting up the axles to make the rear a drive-type setup will probably be the only set up. If anything, see if you can fab a MR2 or Fiero rear into the suspension and the drivetrain will pretty much be taken care of.

 

I'm planning on fabricating my own rear suspension. ie: custom control arms and trailing arms, building my own knuckles. Everything for the rear suspension would be custom built to tie into the roll cage which is going to be welded into the exsiting monobody. The only thing I'm not sure on is the struts, I'm probably going to go with a set of either TEIN or K-sport adjustables to compensate for the added weight in the rear. But given that the engine will be fairly close to the center of the car the weight should be shared evenly between the front and rear struts so I shouldn't have to beef up the rear struts too much. I will also be molding a new carbon fiber rear hatch and removing the glass which will reduce some of the weight in the rear.

 

Why mold a hatch? Webmotorsports sells them.

 

Because I enjoy the build more than anything and I can customize it to my specific application. I don't want any glass in it and the air intake for the engine will be routed down each side of the hatch from the roof. I want something more like an MR2ish.

 

can't wait to see more pics!

 

Definitely the hardest part of this build is setting up the rear control arms and rear suspension in general.

 

Perhaps this is a foolish suggestion but would it not be better to mold the air intakes into the side of the vehicle, for instance like those on the Porsche Cayman... I'm no expert but i have had a few physics courses in my day and the air would reach the engine quite a bit more efficiently... The only difficulty being that you would have to cut into the sheet metal...

 

I have thought about that as well but I am already looking at mounting the intercooler and oil cooler on the sides as they will rely on the air flowing through them with out the ability to suck air through. The turbo will pull air in all on its own but I will be building up small scoops at the top of the hatch to catch some air and help force it down to the turbo.

 

Small update and some pics. I have the large portion of the roll cage/ frame work in and some what done. Ready to start measuring out for the motor mounts and control arms. I work 70-80 hours a week and have 2 small kids so my car time is somewhat limited to say the least. I will keep everyone posted with pics and updates as I go.

 

subsrcibed!!! cant wait to see how this goes!! you are in fact THE man!!

 

Subbed =D good luck and looking forward to the detailed d.i.y

 

never seen a RWD conversion post without a single negative comment haha.

Just a quick question. what is your projected cost for everything that needs to be done for the conversion?
I ask because whenever a post like this comes up everyone says "you'd be better off buying a new car."
I realize that you doing the work yourself greatly reduces the cost, but I'd imagine anyone who wanted this degree of customization would have to do it themselves.

 

This thread is stupid.

Just kidding I hope it turns out sooper kewl. [end white text cause can't do it on AudtoGuide app.]

 

I've thought about doing this with a 2 door Pontiac Grand Prix GTP... I've owned two of them, great cars but need a bit of upkeep. Amazing engine (supercharged 3.8 L67) that responds very well to mods, but putting a turbo on this engine (with supporting mods) will get you 700hp in street trim.. way to much for a wrong-wheel-drive car! Two guys have done RWD swaps that I know of, one is a drag car and the other was a daily driver. One day I'll put this engine in either an S10 or a GTP with a RWD swap...

 

Very cool idea! I test drove a Suby BRZ and loved the handling. (Plus I also love the two door grand tourer look the BRZ and Tib both have) It would be awesome to have a RWD Tib and probably will handle even better then the BRZ as the weight will be pretty much all in the middle of the car. I would maybe even look into using our fake plastic vent things on the sides and convert them to function... I forget their exact location but I'm guessing they're fake brake coolers but maybe something to see if you could get it to work? But great idea! I look forward to watching it happen!

EDIT: I feel dumb now. Was just standing by my Tib on break and looked.. Our fake plastic things are behind the front wheel...

:lolno:

 

Ever driven one of those? Their handling is AMAZING.

 

That was why I was giggling at the idea that a tiburon, even with a mid-engine swap, would out-handle the purpose-built, two-seater BRZ. The tib is a pig, while the BRZ is not.

But, until our OP achieves this feat, we will only be able to speculate.

 

The BRZ I drove wasn't two seater and I don't think any are but I could be wrong... Anyways who knows? The main reason BRZ's are so good is low center of gravity (low car, and the engine is put lower), most of the weight is in the middle (engine pushed backwards), and good suspension. It sounds like he will be distributing the weight like a BRZ and I assume he has a very nice suspension. So who knows? Maybe his car will turn out to be one of the best handling vehicles ever! lol

 

I meant two usable seats- you're not going to be using those back seats for much other than storage.

And again, you're ignoring the fact that the tiburon is still a pig, while the BRZ is pretty light, which helps with weight distribution.

OP, this OT discussion reminds me- look to lighten the car as much as possible. Look to what our friend, @breeechan did with his.

 

What was the turbo model number?
