Need opinions on this RX-7
Well I found an RX-7 around my area (an hour and a half drive). He's selling it for $3500. He's rebuilt the engine and he's got a bunch of mods on it.
Here's a list of what that car has:
-Blue Recaro reclinable seats
-Short shifter
-Greddy turbo timer
-brand new Autometer boost gauge
-brand new Autometer fuel gauge
-brand new dual Racing Beat exhaust
-brand new Catco high flow cat
-Custom down pipe (needs to be modified slightly to fit; ie needs to be bent a tad more for clearance, and the flange I have needs to be welded on)
-4 brand new Sumitomo tires
-brand new kyb 6 way adjustables gas struts
-brand new Tein lowering springs
-brand new T4 turbo
-brand new Stage two carbon kevlar racing clutch
-brand new front rebuilt brake calipers
-brand new dual blowoff valves
-brand new turbo xs manual boost controller
-racing beat fuel cut off switch
-brand new tre performance 255 lph fuel pump
-brand new 4 inches thick 12inch high 27 inches long 3 inch inlet and outlet front mount intercooler
-brand new racing rebuilt internals
-new oil pump
-street port
-new spark plug wires
-new starter
-new alternator
-new master slave cylinder,clutch cylinder,brake cylinder
-new brake pads
-new water pump
-electric fan
-emission block off plates installed
I think it needs a new aftermarket ECU, but wouldn't a GReddy e-Manage work?
All opinions appreciated!!! =]

Here is some feedback from a friend. I think he's right, but would it still be worth it to buy it and then put in a GReddy e-manager?
MORE FEEDBACK PLEASE!
MORE FEEDBACK PLEASE!
Without some sort of aftermarket computer it is just a matter of time before that engine goes. The stock computer cuts fuel at 8.6ish psi. You can defeat that fuel cut with the RB fuel cut defencer, but it will continue to inject enough fuel for 8.6 psi, regardless of how much boost it is making. This will lead to a lean condition, rotaries do not last long in lean conditions! (Lean means too much air and not enough fuel).
You could add a engine management computer, but that is going to be another $1000 or so plus tuning, which isn't cheap.

if you a good with wiring a new ECU wouldnt be to bad to install, the only thing would finding a tuner to tune the ECU for you application. but for all that that isnt a bad price, see if you cant get the price down alittle bit further.
and i dont know what the 2 BOV's are for, does that even do anything to an advantage?
if you want a new ECU, maby look into a Haltech?

I'm not to sure about that intake, and the IC piping is pretty ghetto, yeah two blow off valves?. I don't see that exhaust piping doing anything to keep the IC air cool. I thought you didn't need the AFM hooked up before the turbo, actually at the risk of making myself look (more) like an idiot, I don't recall ever seeing a AFM on a Turbo . Either way, corrugated piping for the intake hose?!

Minus all the technical stuff (I'll just leave that to the ppl who know it) it looks...ok. Has he driven it lately? Looks like **** from all the dirt but not bad with a bit of work. Seems to me he did all that work and just decides the pawn it off on another person b/c he may not have done a lot of stuff right. But im no expert. Thats just what i understood months later after i bought my car. Found more stuff wrong with it than i ever wished. Good luck

The intercooler plumbing may not look so great, but I don't see any major problems with it. The welds look OK, the bends could be better but they will work just fine, and the whole "problem" about pipe heat transfer is blown way out of proportion by well-meaning internet junkies who have no education or experience with thermodynamics.
My concern would be the quality of the "rebuild", as the random painting of components, poor quality of the BOV's, and that mess of an intake do not give me a warm fuzzy feeling about the owner's finances and/or understanding of cars.
I recommend that you take the car to your local tuner to get an estimate on what it would cost to get it tuned with a piggyback ECU or standalone EMS. The standalone EMS would be better if you can afford it, keeping in mind that you could sell the turbo timer and Racing Beat fuel cut defenser to help offset the cost a little bit.
Also, the 4" thick intercooler is probably too thick for street use unless it is designed for very high flow (aka low efficiency).

Out pf curiousity, did you drive it, watch for smooth running (no 3800 hesitation, etc.)?
I don't know about you guys, but that AFM looks way out of level to me.

If your new to Rx-7's pass on that, it sounds like a good deal but thats someones headache your buying. Find a stock car and do the mods yourself. That car looks a bit "slapped together", who knows what the internals or the port job looks like.
Nevrmind the red/white/blue scheme. Captain America would look good whippin it tho.
That car looks like a 17 year olds race car pipe dream. No offense
