Ive been breaking in my engine for 4weeks now, first three weeks I would let the engine Idle at 1900, then 1700, then 1500, then 1200, then just recently idles at 1100rpm..about a quater tank a day. Until This week I tried to start driving. Its realy really hard to drive,and to start. It floods alot, and when it actualy starts sometimes it has d1 white smoke for like a minute, then will clear out. When Irev, its still sluggish like the first day it started, it doesnt rev quickly like how normal rotary is. Maybe sounds a little bit like alawnmover. Its hard to drive, no torq/accel at all, until after 3krpm. I could barely make it up my driveway , i would have to clutch finess... Feels like 30-40 hp...witha welded diff, its hard to make u turns..Is this normal for a engine break in? I just have a feearful feeling inside that the engine is not right. Is it all because its still breaking in??

 

Compression test it.

 

arent you using NA electronics?

 

info on the setup..
s4 Na harness, s4 t2 ecu, s5 t2 injectors, no resistorpack[rerouted], emissions blocked off, rats nest removed, s4 housings, s4 t2 rotors same weight code, fd corner seals and springs,fd apex seals, pineapple medium street port intake side only, new water seals, gaskets, and all. Fmic, 2.5" piping, bov, 3"exhaust piping.
Engine seems to be low compression because it floods alot and is hard to start.

I extended tps wires on the NA harness to fit, and the injector clips have been switched to s5 t2.

anyone had afresh rebuild before? How did it feel for you? was it laggy and slow, flooding?

il try to get acompression test.. its weird sometimes it starts right up, most of the times takes alot of cranking to start..sometimes it floodsss upp thee assssss

 

what afm are you using? have the injectors been cleaned lately?

 

na s4 afm. Could that be the cuplprit? s5 injectors worked fine since the last time I was running my t2 before it blew. It seems like all the injectors are spraying.

when I ran my t2 before, jpr setit up with a s4 na afm and it worked fine for 2 years of dailying.

 

is it a good ecu?

 

i got the s4t2 ecu from Lucky 7[lilred] , straight trade for my s5 t2 n370 ecu. I think it works fine.. I tried running it with the na ecu, and it has the same problems. But both ecus gets the engine running. currently its a s4t2 ecu with moded na harness

all this hassle and stress makes me want to enter the darkside v8, or give up and get a 240. fluck.....ill keep tryinnnnn

 

what kind of shape were the housings in? Edgewear? The s4 T2 ECU is bad on flooding as it is, even on a good motor. They have hot start problems from the factory almost.

 

DONT DO IT!!!

ey dk ill try to make it to your house this weekend! try to get your car running right!

 

the s4 housings are nice, I got em in the 2nd gen for sale parts sect. and the s4 t2rotors are good condition from teddyrx2.

ive searched about fresh engine builds and break in, I guess Ill just have to keep doing what Im doing. I could be just turning abit emo, Il just keep breakin in and hope for the best

Yeah sometimes I have to have abuddy pinch the fuel line to start. or else itl flood and il have to do the whole deflood procedure again..

 

verify the following:

spark at both rotors
ignition timing
ignition wires are attached to the correct plugs


honestly based on your description it sounds like when a 13b is running on one rotor or timing extremely retarded.

 

ill take it off your hands...

 

its getting better today. Before it felt like 30 hp now it feels like 60hp. Ican drive around the streets now, and go with flow of traffic. drove it down to the gas station and filled it up.. I dunoo.its confusing. It started up right away like a normal car, then sometimes it doesnt want to start after cranking so long[until battery is dead]. weird..........I tried pulling the plugs and cleaning them, it usualy helps a lil. The spark wires are rights and spark to front and rear...

 

Is the timing right? retarded timing behaves very sluggish.

 

yeah i believe its right, acid angel checked it by making sure one of the rotors face are pointing out the spark plugs and then linning the crank anngle sensor.

 

Sounds like you may have a bad injector (or two of them). The low power, high fuel consumption, hard starting and other symptoms point to an engine that is flooding very easily.

 

Ok but has it been adjusted with a timing light as per the FSM?

 

engine seized today. It was hard to start once again, and then it started for 2 seconds to 3000rpm, then rpm fell instantly. then it wont even crank now. sad...Its jammed.. Damn.... so sadd today. i keep failing.

 

Engines don't seize for no reason.

Who built this thing?

Did it have decent oil pressure?

Is the oil thin and does it reek of fuel?

 

that's what i told him the motor just doesent do that..im almost sure that its his tranny..he say's its stuck in nuetral..and wont move..i helped him build the motor..but he so strapped for cash he put all used part's inside..witch LOOKED ok..but we all know how that goes..anyway, we thought it was his turbo cause he blew his last turbo motor so the turbo had to have gone with it..we pulled his old one and used whatever he had to use..he got another rotor from teddy and his housing's were in decent condition..we put it together and hoped for the best. we got it started and tryed fine tuning it by ear..i adjusted the timing and success. it got a little better, he was using a s4 n/a afm insted of a s4 turbo one and im sure there's a difference in the two. so it worked for the time being. i then noticed that he had to push in the flapper on the afm to get some kind of reaction out of the motor..when we let the flapper go it died on us. so we then did the unflooding procedure and the atf deal as it could not get anyworse then it was. the pulling of the egr fuse did not work for it..so, by pulling the plug's and cracking it over to clear the motor out we got it to start after all that. i dont know what the oil pressure was as i was not sitting in the car when it was on nor do i know if the factory gauge even worked in it..we let it warm up and i started to adjust the idle it would not idle below 1100 to 1200 rpm and i dont know why..i was thinking it was the tps out of wack since he's useing a s5 tps wired up for only use of one tps instead of two..he's also using a s4 n/a harness for a t2 motor..i think that he's using a s4 t2 ecu as well..he replaced the turbo and after said it was running a little better, i told him that it had low compression to begin with so that AND t2 rotor's with low compression = p.i.t.a. and driving it would make it better over time. witch it did..as for this little problem? i have no idea what caused it..that's really all i can think of from the point that i got involved.

:AA:

 

i was also thinking that it was his injector's too. cause i dont know if they were in working order or not..i think i asked him but im no too sure..if he's certain that its the motor then we are going to pull it apart on sunday and see what happen's..
i strongly believe that its not the motor and its something else..but i could be wrong..

:AA:

 

Didn't JPR touch your car?
I think that explains it all...
Did they do the rebuild too?


-Ted

 

jpr did touch his car and from what i hear from him they fucked it UP...never have i heard or seen these thing's done to a car..he got screwed bad by them..

and no we dident have a timing gun to time it with..we had almost nothing but our better judgement..i dont like doing that personally, i like doing everything right the first time.

:AA:

 

after reading your paragraph acidangel, does sound like his car has been mickeymouse'd together..

sure his tranny is not locking the motor? maybe put it in gear and try moving the car?
