theres evos all over the country doin 10's on stock turbo

I guess the Rousch 700 hp endurance race 2.3Ts slipped by all the import guys... lalala.
Though obviously a 4G63 is a more sophisticated design.
I agree that 4G63s need to be in more RWD chassis... all the FF sports cars that power understeer just cry out for AWD or a longitudional layout!

I just ran 11.9 with my 7-bolt 4g63. The only internal mod I have is cams. I'm still running a small turbo, a small 16g. It has definitely reinforced my desire to own a RWD 4g63, and it just so happens that the FC should be an easy way to accomplish this!

Respecognize!
IIRC, isnt the Turbo tranmission a one piece case? ie, the bellhousing is cast with the rest of the transmission?
so you would need to swap the gears from the TII into the B2600 trans?

additionally, DSMs do have some crappy supporting items. case in point, the window regulators...
alternators...
any switches.
but i do know what 4g's can do. i raided the B2600 at my local yard for the front diff for the first gen. might beed to get the motor and transmission while im at it...
wait....there is a starion at a yard...hmmm...needs a motor....hmmm....

cool deal. i got a spare TII trans for free, the b2600 motor and trans for 200 bucks from the scrap yard.
now here is my own problem...
do i 4g a first gen? ( i have lots of rotary cars, so dont give me the whole "gah! piston!" thing.
or do i get the starion from the scraper, use the TII trans and solve the weak RWD transmission link...
though im sure the 4g might destory that transmission...

I was not going to post this here, but here goes nothing.
I have heard rumors, but am still yet to find anyone to complete this swap. If any of you have proof of otherwise, please let me know. I have searched for days and have yet to find anything more than hearsay.
FC+4G63=700 reliable daily driven whp with one of the best RWD chassis to come out of Japan
More updates coming soon.
Now, before you guys start crying about my power claims-
My Colt ran for 3 years, 1 1/2 of which with 700+whp. It never popped a motor, and was driven every day it was not snowing. It had full interior, heat, radio..ect. And, at less boost than what I made 708whp with, it ran like this...
http://videos.streetfire.net/search/...318845ffb1.htm
Hell, with a bone stock motor-It still went 10's all day (498whp)
http://videos.streetfire.net/search/...55836b6b28.htm
The car was never in its life towed to or from the track. Not once. On pump gas it made over 500whp. 700+ was trip to Marathon away, since I made that on cheap old 110. to that end, it was turned up and raced every nice weekend and on certain week days. All this, and the motor is STILL making great power in its new home in a DSM in New England. My power claim is not a goal, not one powered by hopes and dreams, but a simple matter of -I did it before (with almost nothing) and I will do it again. The car simply wont make any less power than that. If it did, I would be making a backwards progression from my last project-one that was completed for $5200 total invested-and that is simply not going to happen.
Don’t get me wrong-there is nothing wrong with the rotary engine. I have built and tuned quite a few RX-7’s now, and I enjoy the cars overall. If I wanted a 400whp DD, I would keep the rotary, but for the power I depend and the money I have to spend-It is nearly an impossibility to have such a power level in a daily driven rotary powered car.

yeah somehwhere in the back of my mind i thought the hatch decals looked familiar and the hat on the roof...
anywho, once again, impressive.
might be picking your brain on turbo dodge stuff for a first gen.

148 mph, damn! Way to keep the Colt looking dead stock, too. 
Good to see someone doing this swap. I'd be starting mine already but I don't have an FC anymore... and I'm between jobs, so now is not the time to be buying. But I have a prospective opportunity up in Michigan, so chances are I'll pick one up up there and start building.
BTW, over 500 whp on pump? That is great! You guys get 94 octane in Ohio, right? Regardless, that's some awesome numbers.
Two more questions about the RX7: 4g63 or 4g64? And what EMS will you be using?

Ya wanna know why I hate DSMs:
This was my first gen plymouth laser RS '90. 6bolt motor. timing belt broke. Instead of bending the valves... It just decided to split the camshaft in two and scrape the crap out of the cam journal. Had it all of a week. My last bout with performance on a piston engine.
Heres the horror shots:

I agree, I’m sure this falls on mostly deaf ears. But it doesn’t matter if it was a nuclear fusion forum-Failure due to lack of maintenance is the owners fault, not the car's fault. Simple as that.

No offence, but this is an example of what I was referring to-owner mis-matinence giving DSM;s a bad name. If the timing belt was served at the correct interval, hell even 20k past the service interval, that would not have happened. You cant blame a car for breaking due to the owner's mistreatment.

Well.. I mean DSM could have designed the engine so that you just have to replace the timing belt when it breaks... Instead of replacing the timing belt, head, valves, camshafts... etc.
Regardless, I have no idea how the previous owner treated the engine. I can only assume that he didn't properly replace the timing belt or the shop he had do it did not do it correctly as the belt appeared brand new. I only owned the car for a week before this problem. Parted it out and got my money back.

So they should have designed the motor with the mindset that people will mistreat the car, and when it fails, it will fair "cheaper"?
Most 4 bangers sold today are interference motors-and any 4banger worth a damn (power wise) will be an interference motor since the valves will intrude so far into the cylinder allowing for ridiculous stock head CFM numbers that make us love Honda and DSM head so much.
It sounds like you were sold a time bomb, (and you realize that now) beaten to death and then sold to someone who didn’t know what to look for when buying a DSM. Again, not the car’s fault in either respective.
