87 tii, rebuilt with 55k on it, idles glassy smooth, mechanically sound, good pulling turbo, includes a blitz dd ss bov and full racingbeat turboback and s5 tails. no accidents, clean title, no broken interior pieces, straight frame, all body panels, no large dents or dings, good paint. cons: not working drivers power window, bald tires, power steering is out, turn signal light is out missing two of the lights on the bumper(the ones at the forwardmost part of the bumper, just above the foglights, not sure what they are for). what do you think is a reasonable price for this car? they want 3600, i think its fair but am i overpaying?

yes thats fair if the body is nice

How many miles are on the chassis?

That's about what I paid for my TII up here in the NW (TII's are rare)...

Sounds good to me. Make sure there's no smoke on start-up or at WOT etc.

Also, DO A COMPRESSION TEST. This will (IMO) determine what the car's worth.

Around 100psi+ is what you're looking for (search for 'how to')

BTW, there's a great link in the FAQ, or archives (or fc3spro.com) on what to look for when buying an FC.

ok, yeah the main thing is because the body is very straight and the engine seems very healthy(the two most important things) that it is worth that money. im going to see what my options are for a compression test and i know thats very important. there's a little over 200k on the odo and there's been paperwork since day one including the engine rebuild. there is no white smoke or any abnormal smoke coming from the exhaust at any time, it starts up really good the first time without any trouble.

Sounds good to me. I got my 87 t2 with 155k on it, all stock for 2k + a gxl. It keeps having problems left and right now.

i like to call problems with my rx-7 "bonding time" haha. did the engine have 155k on it when you got it?

RETed

I would worry about fuel with the full exhaust on there.
Was the fuel pump power rewired or upgrade fuel pump installed?

i dont know about the fuel pump power being rewired(what is this?) and i doubt a new fuel pump was installed. tell me the problems that could arise from this. the current owner put the exhaust on and put very little miles on it, probably 5k

RETed

If the motor isn't hurt by now, it'll be dead in about a month or so...

Reted, your telling him that the engine will go bad because the owner put a full exhaust on his car, without upgrading/rewiring the fuel pump? This makes no sense to me

Reted wakes up in the morning and says "i'm gonna go scare some noobs"... it's just his way. He would rather everyone be afraid the worst possible thing has happened than let anyone have hope. This isn't a jab at you Ted... people need it.

This is why...

I've seen 3 people blow their FC turbos like this...exactly.


-Ted

And I've read about a bunch of them. You still like to jump to conclusions.

ultradef

A full exhaust causes boost to rise (especially if your wastegate is not ported), which can cause a lean condition. Upgrading/rewiring the fuel pump will increase the amount of fuel to help compensate for the increased boost. Mazda did include a fuel cut to attempt to combat this overboosting problem, but the fuel cut itself can sometimes be what causes the engine to blow. IMO, an ignition cut would have been a much better solution.

88rx7gxl

Jesus some of you are over reactors... You all really think just adding an exhaust will blow the motor if the fuel system isnt upgraded? So, what your telling me, is the stock fuel pump/wiring is ONLY good for the exact boost/hp levels the car had from the factory?? ANY boost/hp increase over stock will grenade the motor? I think some of you are on crack.

A lot of experience goes into those conclusions. The wastegate, fuel, and ignition systems were designed using the pressure losses inherent to a factory, quiet, emissions controlled exhaust. While there is some saftey factor built into the system those reasons coupled with the age of all components involved especially the long runs of fuel pump wiring can cause lean conditions. Lean conditions kill forced induction rotory engines.

These are all widely accepted and repeatedly proven facts.

You're welcome to your own conclusions.
I just thought I'd help by offering some advice.


-Ted

88rx7gxl

ReTed, You always seem to offer pretty good advice. It just seems your really quick to jump on the "Your ***** Gonna ****** Blow" bandwagon.

Rocklobster - Lean conditions are bad for ANY combustion engine. Not just a rotary. With a new exhaust, shouldnt the AFM notice that airflow is better, and have the ecu richen up the mixture?

RockLobster

iTrader: (7)

Most pistion engines will tolerate lean conditions better than rotory engines. Same is true with dirty coolant or dirty oil.

I could probably run my integra for a VERY long time with dirty oil and coolant while fuel starved. It would not run the best but engine damage would not result nearly as quickly as with my seven. Part of the deal.

RETed

Well, blowing engines is not exactly something "cheap
to fix...


Yes.


Backing out all the numbers, the stock FC turbo fuel pump can safely support 250bhp at the flywheel.
The same goes for the stock 4 x 550 cc / min fuel injectors.
So yes, the stock fuel pump (and fuel injectors) care barely sustain power levels that are stock.
I would never try to run either past 200hp at the wheels.
Absolute maximum would be about 220hp at the wheels or so.
Going past that is asking for trouble.
HP at the wheels numbers are on a DynoJet.


Stock S4 FC turbo puts down about 160 to 170hp at the wheels.
I wouldn't go over 200hp at the wheels.
This is approximately a 20% increase in power.

Like I told kontakt, you're welcome to your own opinions and conclusions.
I was just trying to offer advice.

True, but rotaries do NOT take well to detonation...they are more "fragile" than their piston counterparts. One ping can blow an apex seal.

NO - FC's run pretty rich from the factory, which gives you a little headroom for increasing horsepower before upgrading the fuel system, but not much. After that, fuel upgrades (new fuel pump, bigger injectors, engine management) are recommended. But what do we know...feel free to experiment with this on your own. Just make sure you have some money saved up for a few rebuilds.

88rx7gxl

Yes sir Ted-Dad sir... No wait, **** that.

I swear that you ppl have probably forced MANY people to rebuild their engines when it wasnt needed. You ppl respond to "my car is flooding" with "oh, your compression is low, must be rebuilt" as your advice. Every case of flooding is poor compression? I dont ******* think so.

Q: "I want to add a fartcan muffler to my car"
A: "you add that muffler your engine will die within 10 miles"

Q: "I accidentally put 97 octane gas in my car, i usually run 87 octane. will it hurt my engine?"
A: "Welp, get ready for a rebuild. The excessive deposits in high octane gas will melt your apex seals. You ruined your motor"

Q: "I tested my compression, 90psi on all faces. Is this good?"
A: "God No! Im suprised that thing still starts. Rebuild asap!!"

These are the kinds of responses I see here all the time. Worse case scenario as the FIRST reply to a new thread. Do you just like to try to **** in peoples cheerios?

I hope that wasn't referring to me.
I'd like to see PROOF of me saying all of those things?

Those were mearly examples of how most questions get answered around here. No, its not only you. But it seems with every question that is asked, the worst possible reply is given. It annoys the **** outta me. Oh well, **** it.
