Bad signs? (time for rebuild)

[markrx7]

mine sounds a lil like this but i wouldnt say the idling was rough... just tends to rev high for a lil bit then drop down to around the 1k mark... i always thought they were supposed to rev high for quite a while?

But then again mines on 80k miles and no rebuild apparently, runs perfectly tho and got 276atw a couple of weeks ago so maybe i aint due for one just yet?

got a coolant leak atm tho really gotta get that fixed, gonna watch this thread and see if anymore problems that i have come up here, if so, im gonna get down to rotechnics for a comp check!

Well had Pip on the phone earlier!

Apex seals and springs have gone...

Housing have minimal wear. An engine mount has gone and there was an injector leaking. He\'s replaced most of the bushes now for the Powerflex items I gave him aswell, hoping to have the car ready for end of next week!

JEEZ!  :2eek

i feel for you fella

well mine still has problems after my visit to a specialist and to be honest he didnt check very much. so i am in a position where i am just so disapointed and desheartened i just dont want to take it elsewhere or do anything to it at the mo, even though its on my mind all the time

[Ian@TunerUK]

Well if you don\'t mind the travel I\'d recommend taking it WGT, Pip certainly knows his stuff!

[Ian@TunerUK]

It\'s back on the road!!

Picked it up this morning, just got the annoying 1000 mile run in now which is going to kill me!

Pip has informed me my engine also has a bridge port! :2eek So an Apexi will be sooner rather than later I think, he reckons we can get another 40/50bhp from a decent map, does that sound about right?

[Grizzly]

Your running a Bridge on a Stock ecu??

[Ian@TunerUK]

It would seem that way, there\'s nothing on the receipts when I brought the car, so I didn\'t know to be honest!

Pip seems to think it\'ll be ok for now, it\'s a bit rich low in the rev range but he plugged an Apexi in and even with the base map it was a different animal!

[Grizzly]

I\'m a bit confused? you would know if it was a Bridge, them more back pressure (stock Turbo\'s, cat etc) the worse the Bridge will run.

Is Pip saying don\'t run any boost on that Ecu? tbh it would worrie me that the map in the car is not correctr for the Timing on the engine.

[Ian@TunerUK]

The car has no cat on, how big is a bridge port? Perhaps it was only a small port, I\'m still learning about all this to be honest :3Confused

He was fine with it the way it is now for the time being. I\'m only running it in at the moment, so there\'s no big load being put on the engine.

[Grizzly]

So your saying you have a Half Bridge with stock turbo\'s etc, stock ECU and decat!!

Size oviously matters but in a Bridge they alter the Timing so much that its a Problem for ecu\'s set up for stock port timing, it may help if its small but its still not good. I realy hope you have some sort of aftermarket ecu there.

All i can say is Drive carfully and don\'t get it on boost (if that possable with a Bridge on Twins).

[Ian@TunerUK]

The thing is, it\'s probably been set up like this for about 6 years? I\'ve only owned the car 6 months, I\'m a bit worried now, I assume Pip knows how it should be running, I\'ll be getting an Apexi next month anyway fingers crossed so it won\'t be like this for too long!

[G@NDY]

Im sure pip knows what hes doing matey:bandit

[Ian@TunerUK]

Im sure pip knows what hes doing matey:bandit

I hope so considering how much I\'ve just paid him for various work! :rollin

[Ricco_04]

As long as you dont go 1psi over standard boost then the ECU should be able to controll the fueling fine surely?

[Grizzly]

Thats not the problem, its the engine Port Timing and if you\'ve ever driven a Bridge you\'ll know its verry hard to drive it off boost (seems to be there all the time)

Just imagen how much more air you will be getting through that port to the same amount of fuel?

as you say i\'m sure Pip has done something to stop it coming on Boost or to cope with the extra fuel needed but i think if pip has said its ok i proberly think he means its ok to run in on (i.e. no boost and under 4k)

If its not a daft question how did you not pick up it was a Bridge before? Has it never idled smoothly? I know with small turbo\'s the power etc is alot less but when i had a T2 running on a bridge it ran realy badly, i was told that the turbo was increasing the overlap effect by not letting the exhaust gasses out at low rpm.
