I finished the car around 12am Saturday night, with intentions of bringing it out to the shootout that was then rained out. The bottom end has been finished and in the car since last year-but I waited 7+months for a head that I still done have, so I went to the yard, got a head off a junk Elantra for $30, and the trash was on. In 5 days, the turbo/cooling system and wiring was built, fabbed, and installed. There was MUCH more fab work than I anticipated, and thats why the car was not at the show Saturday.

I will answer specific questions, but here are the cliffs notes.
2.4 Liter-Eagle/Weisco assembled by me
heavily used ACT 2600 w/6 puck
100% stock Rx-7 driveline
Twin China 50 trims
$50 "Bo-Bo" manifold, mig welded, ugly, hilarious!
JMF intake (thanks Jim!)
Q45 TB
1600cc
DSMLink (the BEST for your DSM)
twin 2.5 DP's to 4 inch made from scraps exhaust
Modified $140 Ebay intercooler
Honda Rad in inverted V-mount confg.
Stock head/cams
Sleeper Cage

As for the TT-I did it just to see if it would work. I know its inefficient on a 4 banger-but at what I pay for these China turbos, its worth a try. IF it doesn't work-no big deal. It will have a GT42 back on it within a matter of days.

A Budget that would make most cry. I have not ran the numbers-but as it sits I am 99.9% sure its well under the Colt's $5200 total investment. I know it will be up for debate with MAP's FD-but since I have had the initial intention,and had the motor in since 06-is it safe to say this is the worlds first documented 4G RX-7?


Track times, and a **** ton of video to come

 

Nice swap,I dont know if i missed it or what but what is that motor out of?

 

Very interesting! I have to say I like this better than the LS1 swap

4G64, out of a Mitsu truck, with 4G63 turbo guts and head.

A lesser combo made 708whp at 30psi on my old daily driver.

 

right on you made a manifold for my buddy timmy, top mount on a green 2G talon.

 

Not me necessarily-I was Sales/Tech/Finance at the shop.

This whip was 100% build in my 1 car garage.

 

ahh thought maybe it was ron, cool 7. I didn't go to the shootouts this year because of the rain, but one of my buddies took some pictures of a 4g63 FD which looked nice. I do like that swap into 7s.

 

Update- 15psi by 5000rpm in 3rd gear. It comes on much harder than I would have thought! I need some more gate spring to see 20+.

Dyno time this week hopefully, I have it just dial in on the street tune.

 

Well done buddy. We'll meet at the shootout next year. I will definitely be done by then.

 

Cool! Maybe a new revolution has been started?

 

Cool!
