Has anyone ever blown a motor from not porting your wastegate?

Hey Johny, Got the check. Your a good man. I don't want to port anything. I just want a new exhaust and it doesn't have to happen today. I'm just thinking about the future. The exhaust is fine, just has a little rust. I could just replace the exhaust with oem exhaust but it's 4 grand(not happening). The exhaust will probably last another 10 years or more. I just like the way rb looks and sounds.

Thanks for your help and the car.

HOLY ****. For the love of freakin god port the damn waste gate. I'd personally port the gate, get 720cc secondary’s and run an rtek (along with an intake). The FCD is GARBAGE and Racing Beat will also tell customers that anything over 350 RWHP is not attainable on a street car and it will take $10,000 worth of mods (They actually told me this on the phone after I told them my 60-1 turbo plans and I wanted them to balance my rotating assembly).

I have witness 3 cars PERSONALLY BLOW due to the old RB Rev 1 full exhaust and the REV2. All 3 cars were running an FCD and nothing else. You happy now? And I told all 3 of those idiots to up the fuel in some manner, but none of them listened. 2 of them got out of the rotary game all together and the other got a rebuild that I helped drop in... And guess what? We stuck 720cc injectors in it 2nd time around.

Your mind is obviously already made up, you'll read 100 post saying to port the WG or add fuel (I say do BOTH), but your stupid *** will cling to 1 ******* reply saying you’re safe.

GOOD LUCK, after it blows, don’t get discouraged and sell all your Rx-7's.

dude... why post if your going to ignore an absolute safe way to take care and ovoid popping your motor? I have to agree that reading your posts makes me livid at how very well you do not get the picture.

Racingbeat tells you that you will need an FCD (fuel cut defensor)...? Yeah, b/c they make one and they want you to buy it. An FCD is basically lying to the ECU telling it that its running less boost than what is actually is. Ok with that being said, where is the extra fuel for when it boosts up past the stock limit? Which it WILL w/ the REVII turbo-back.

Quit being a dipshit and port your waste gate... its not that hard, weld an extra washer on the flapper door to compensate for the extra area that is drilled out.

Buy yourself an Rtek to be safe. They are definitely worth the money. Instead of lying to the ECU... the compensate for the extra boost up to an extent and add fuel and retard the timing a degree per PSI above 9 lbs.

Your looking @ maybe $150 depending on what Rtek you go with and maybe a full days work. I really do not have faith in you but whatever.

It is really sad to find out that you got that 10AE that has 7k original miles on it and you are posting **** like this and ignoring some good advice that people are throwing out there. But this day and age... I guess anyone with money, the owner would be crazy to let the deal pass up.

It's a pretty dicey thing, I have a ported S4 WG on a hybrid turbo on my car, with a 3.5" straight exhaust I still get nasty creep, my fix was to reinstall the cat, now I'm legal, my girlfriend doesn't complain about the fuel smell, the car is quieter AND I have no creep.

Don't blow it though.

plus its a 10AE with 7k miles are you seriously going to be driving it that hard or Driving much at all?

to each its own but if are going to be driving this thing to its limits port the waste gate and get a Piggyback comp for the fuel and air mix like a HKS Fcon. or Rtek mentioned all over this thread.

I'm done trying to convince you.

Reread my last post and I explain BOTH of my setups. I've done nonported then ported and now nonported(time constraint).

These are the type of people that give rotaries a bad name.

Oh, that piece of **** blew up on me!!! Rotaries are crap!!


hmmm. Maybe if you did it the right way the first time.....

You must have skipped my post, ohh thats right, you don't comprehend what you dont want to hear, all you want to hear is "you'll be fine with a FCD and no porting". Hey wait, maybe that will make you read this post!

If you read my post, I've seen 3 engines blow from full exhaust and FCD, no added fuel or ported gate. And your still counting 0. These were in my neck of the woods, my friends, not what I've read on the net. I personally havent blown an engine because I'm not stupid and havent had bad luck yet (like a shitty tank of fuel or something just go wrong like a locked injector or air temp sensor failure etc.)

So your friends blew their engines. And you called me a stupid ***. You would think the second guy would have listened to you. I don't know...sounds fishy to me.

I want to keep the car as stock as I can. It has 8200 miles on the clock. Putting on the exhaust is not something I have to do. I like the way the rb looks and sounds. Actually, the original exhaust is still very good. Just has a little rust. I just wanted to see if there was anyone out there that ran the REV II without porting the wg. I talked to Chris at Banzai and he says I would be fine without porting as long as I had the fcd. He also knows I'm not going to race the car.

of course there are people that use that exhaust. there are people running 100 different exhausts with stock wastegates. having a ported wastegate is completely un-noticible (unlike an aftermarket exhaust).

Sounds fishy?!?! Because you don't want to believe it. Hey buddy, search my ID and ask anyone in this thread and in the tide water area of Virginia, I'm an honest fella and just trying to help you out. Second guess my honesty for what??? so I "win" in this stupid thread?? F*ck you I'm done here. You win the d!psh!t award. Porting a wastegate is internal and will never be seen and it will only IMPROVE the car in ever single aspect when it comes to boost control.

Porting the wastegate would not depreciate the value of your car. In fact, I consider it a reliability upgrade.

Thanks for being the only person to actually answer my question.

Was the car stock besides the exhaust?

Well usually as people mature they become more understanding about reasonable advice to protect your stuff. If the car is a toy then run wild with it. But what is the point of trying to have fun with something if you are risking blowing up a decent running engine. Yet you continue to disregard advice from people that have done buildups of cars that are reliable and are trying, as your internet buddies, to keep you having fun with your car on the road.

Can we get another addition to "noob of the year" even though he's a 2005?

I have the rev 2 turboback and my boost creeps from 7psi in first to 18psi in 5th. im not porting the wastegate because i am installing a bnr hybrid which already has the wastegate ported (infact its in my avatar)

why hasnt my car blown up? 750ccs all around, safc, fcd, lm-1, tune, and i dont gun it in 5th.

I had an s5 wastegate ported to the edge of the flapper and it still creeped to 18psi when it was really cold out (summer it was fine). That was with a straight through 2.5" exhaust and a large streetport. I detonated the crap out of the car as I was lining up with an 03 cobra, but it survived (probably the RA Super Seals helped).

Holy ****! I got a pm from a guy that said the same thing. On a cold night he popped in 4th gear. But with a stock motor with rev ii/fcd only.

Thanks for your input. LOL and thanks for not slamming me.

I had a REVII on a stock motor and a FCD and ended up blowing the turbo (the bearing went bad and the turbo basically ate itself in 4th gear on the highway....)

I then got a new turbo, put it on and got a boost gauge, and on the highway I was easily hitting 20psi... which is about twice as much as a stock turbo can reliably do. and this is an S5 turbo, so yours will probably be worse.

if you want to be able to ever actually floor the gas pedal without having to worry about blowing the engine and/or your turbo (which I assume you want to keep original), I would definitely port the wastegate.

^ 20lbs on stock fuel? and its basically blowing hot air past 12 lbs and maxing out the efficiency then anyways.

Sir, you received more than enough info in this thread to answer your question.

You are on an enthusiast site. The people on these boards actually care about these cars. There have been many threads that I have read on this board where people have popped their engine because they did not do the proper supporting mods. Of course your gonna hit a nerve when you come on here and want to do the same things that have been proven to be a path to failure and you ignore the advice being given which will save your motor.
