Well, we all know how it feels to be the new guy in a forum and to ask dumb questions that might be found elsewhere..

Well Ive been nissan man for the past 4-5 years, ive had like 6 240's. 1 s14 and 5 s13's. About half of them were modded with my newest one being heavily upgraded motorwise. Well i just traded my s13 for a 91 TII....

heres the questions.

I traded knowing that there was something wrong with the car.."rear apex seal" from what i was told.

Now the question.

Im fairly low on funds right now, with only about 1200 to spend. And my knowledge of the rotary engine.. well i don't have any.

I know i can buy another jdm engine for 1200ish but would that be a non smart route to take? Its always a risk buying a used engine as i already know from buying plenty, But as far as rotary engines go, i don't know.

The car right now has plenty of stuff on it

-OS Giken twin-plate clutch
-T4 Garrett hybrid turbo w/external wastegate
-Tanabe race exhaust
-HKS Super Mega-Flow intake
-Greddy FMIC
-Blitz DD BOV
-2 additional 470cc injectors on custom intake-side IC piping and elbow
-HKS AIC (additional injectors controller)
-HKS PFC F-con
-HKS SBC
-HKS EVC
-HKS turbo timer
-Koyo Aluminum race radiator
-Dual-belt alternator pulley

well thats it engine wise, aside from it not running..

Just any input would help, whether neg or pos

 

first off compression check it and make sure that it need to be rebuilt

 

yeah deffinatly. The thing just reeks of fuel, it had to much fuel in it that the turbo was full of fuel..Unless the dude had the additional injectors turned on high and just made it so fat it wouldn't run anymore

 

I second the motion for a compression test before pulling the motor.

If it is blown, the first thing you need to do is pull the motor and disassemble it, to find out what's damaged and needs to be replaced. Chances are, if the rear-rotor lost an apex-seal, the rear-housing is damaged and will need to be replaced. The rear rotor AND the turbo might also be suspect as well.

Once you have everything disassembled and inspected, then you can decide what you should do--whether to rebuild what you already have, install a J-spec and cross your fingers, OR buy a J-spec and rebuild using the best parts from both motors.

 

Won't flooding cause a compression loss? If so, un-flood it, squirt a little mmo in there, and do the compression test.

 

true. but isnt flooding a sign of a bad seal

 

any other ideas about the extreme flooding? It was driven really really hard for a few hours, then started idle funny and is just flooded like no other, like there was gas in the exhaust, thats how bad it was

 

You need to unflood the motor by removing the lower spark-plugs, pulling the EGI COMP fuse (to kill the fuel-pump) under the hood, and then cranking the motor over while you hold the gas-pedal to the floor... Crank for 10 seconds at a time, and repeat until no more fuel-smoke comes out of the spark-plug holes. While you're doing this, listen to the motor as it turns over. You should hear a consistent and powerful "pssh, pssh, pssh, pssh" from the spark-plug holes as the motor turns. If you hear inconsistent "psshing", this would be a bad sign, because it would indicate either a cracked or blown apex-seal (likely).

If everything sounds good and the smoke has cleared, then I would install everything and start the car. Basically either the motor is blown, or it has a terrible tune--which wouldn't be suprising, considering that whoever built the car was trying to run a full turbo setup using the stock ECU and piggy-backs...

Do you know what fuel-pump is in the Rx7? If it's stock, then that's a huge problem, lol.

 

i would also check the spark. obviously if it can't burn the fuel, it will flood.
and the only thing on unflooding it that i would do different is i would remove all plugs and replace them or clean the dickens out of them. been many times i've flooded and changed the lower plugs only to have to change the upper ones too for some reason.

oh. and welcome . check out www.nopistons.com also. another great site.

 

Welcome aboard!

 

well since i posted that im new, and posted my problems.. i will post a few pics of my car as well

some of you may have seen it before on here along time ago.

 

damn. that is clean. did anything help?

 

haven't had time to mess with it. the battery is dead and im lazy

 

flooding could be a lot of things. fcs flood when u shut it off before its warmed up anyway. but leaky fuel injectors are also a cause of repeditave flooding.

 

it also has the extra injectors on the intake pipe, and the person who owned it before me had those cranked on full for 4 full hours of driving. Its a low milage engine with only about 50k, so i just think theres a fuel problem. Not a blown engine
