4g63 in a rx7

The Starquest motor is junk. That is why there are people with Starquests shoehorning 4g63's into them. Why would they give up .6L of displacement and go to the trouble of an engine swap? Because they're gaining a really well-designed DOHC head, multi-port fuel injection, and a motor that doesn't blow head gaskets when pushed.
It's also not that hard to find a 4g63 wideblock. It's very easy to find a 4g64 wideblock. I'd say, it's probably easier to find than a Starquest motor in good condition. They're not very expensive either. Given the enormous technical advantages of the 4g63, it's no contest versus the Starquest motor.
The 4g63 is itself a tank. They'll handle over 500 hp with stock internals.

And, before anyone questions his claim of a stock motor making 500whp-reliably-I made 498whp 425ft lbs on a bome stock long block, and ran with that set up for 5 months until winter a few years back. This is how it ran at the track.

the chrysler conquest tranny will bolt up to the 4g63, ive seen a few rwd converted talons where the motor was turned to run front to back with the car,, kid had lil over 3500 in the whole car, basically needed a custom driveshaft, mounts, few other things, i beleive its real possible to drop on in an rx7, plenty of room, nice front cross member to mount it into, id try it if i had a spare shell and motor
Conquest tranny is not one for hanlding any type of power. I would feel more comfortable sending the power though an NA FC trans!
I was serious.

The starquest box is one of them. -Also, the starquest trans WILL NOT bolt up to a standard 4G63 found in turbo and NA DSM's.

Yeah, you'd need a wideblock. It's the same bolt pattern as the B2600 bellhousing. If you've already got the RX-7, why screw around with a crap Starquest tranny?
coltboostin, you were just joking, right?

Someone is awake-
On both counts.
starions are poo.
RX-7 transmissions are poo.
If you're taking the rotary out, put a damn ls1/t56 in, you'll be happier and your car will be faster.
busa's are slow.

Just found this thread, i'ma mitsu geek and have always wanted an rx-7 but hated the reliability of the rotary. Sounds like a perfect swap for me. As far as crank walk goes, its all due to the flywheel step being machined wrong, fixed two dsm's and a Gvr4 and they all had the flywheels incorrectly machined. And the blanance shaft belt breaking is due to people incorrectly adjusting belt tension or not keeping up on their upkeep.

hey you know, puerto ricans had the fastest import(not sure if it still is.) And it was a old mirage with a starion/conquest motor. Carburated turbo. it was in the 7's like 6 or more years ago. I believe its in the high 6's now

That was Sakura-and the Head was a one off billet peice(believe the blick was as well) A stock 4G63 is more of a starion motor that that thing was!
And just FYI-there are 4 bangers in the 6's not. EX-Brent Rau-stock displacement, stock block 2.0l 4G63- 6.98@199mph. Motor has lasted year+of all out flogging...

DSM = worst car I ever owned
By the time you reengineer all the design defects out of a DSM you will need to convert it to hydrogen. It will be the only fuel available at that time.
Good luck.

Ok, lets take a 60k mile 2nd gen eclipse and a 60k mile 2nd gen n/a and beat the **** out of them without performing any of the recommended maint and see which one blows up first.
