recently my motor has gone from bad to worse. it burns collant and iam about to rip out the damn add coolant light. I have my new (well used) jdm motor on the way but before I put it in I thought Ied have a little fun. Ive got a midpipe just sitting in my garage just begging to be put on and yes I am on th stock ecu. what I want to do is just throw a boost controler on it run it at 10 pounds with the midppe and see how long I last. The thing is is that my turbos are later model and dont have the restrictor pills. my question is will I be able to lower my boost once I put on the boost controler or will I have to drill out the nipples or something like that. any info would be great and please dont give me the you need a stand alone speach I already know this idea is stupid.

 

AWSOME!! I've always wanted to rag on an almost dead motor. My luck... i always get good parts. (you always want what you don't have)
sorry, can't help you with the restrictor pill question.

HAVE FUN!!

 

i know you may be pissed at the motor, but non exploded ones are normally better part sets then exploded ones.

 

just use a manual ball/spring boost controller and yank out those pills, they work like a charm and costl ike 15 bucks from homedepot.

 

You might check this thread on some ideas:

Or you might consider not shooting apex seal shards into your perfectly good turbos for no good reason.

 

what model turbos do you have?
what you don't want to do is go over 10psi and blow a seal through your new turbos

try a manual boost controller its cheap and works

and just like you said I assume that your motor wont last as long because boost tears apart the o rings more.

 

the turbos are preety much brand new they only have 14k miles on them they were bought by the prior owner a little over a year ago. what iam saying is I dont have restrictor pills and I now when I put on that MP my boost levels are gonna go sky high so I want to turn down the boost to stock 10 lbs so my question is can I turn the boost down with the way my turbos are set up??? once again I dont care happens that and iam not going to be driving it like this forever just untill my motor gets here. any info would be great.

 

what boost are you getting now?

if they are new stock turbos then they should have the pills

how do you know theres no pills? if theres no pills youll get low boost on the primary and crazy boost on the secondary I believe

take the wastegate pill out, thats all you can do to lower the boost you want as much pressure as possible to go to the wastegate actuator. On a mild streetport with that pill the boost was creeping from 7-12 at redline.

 

There are versions of the turbos that have the restriction built into the nozzles instead of using pills.

 

THATS WHAT IVE BEEN TRYING TO SAY!!!!! do you know of a way to lower it with this set up and btw my boost pattern is 10-8-10

 

You'll need to drill out the nozzles and then you can install a boost controller (whether manual or electronic).

 

Ball joint,

There's no point destroying an engine with bad water o-ring seals. BTW: Ever seen an apex seal through a turbine wheel?





Don't be a Jack ***!

All new replacement turbos have integral pills in the nipples.

You can simply put a manual needle valve in the hose from the wg actuator to the solenoid vent valve. start closed, should be about 9-10 psi.

 

BINGO!!! This it the MAIN reason not to blow the engine up. You do NOT want to throw apex seal pieces at a turbo wheel that's spinning at 50,000 rpms +.....YOU WILL RUIN YOUR TURBO DOING THIS...

 

9-10 psi with the MP on?? or 9-10 with the stock system??

 

one more thing read this post before you keep saying stuff about apex seal shards going into turbos.

The link is dead, and if you do this, get a few runs on video!

my bad

 

What's that got to do with anything?

We're saying that if it DOES blow you have a chance of dusting your new turbines.

Why take a risk like that when you can control it?

 

instead of doing the mid pipe thingy or in addition, please put water injection on the car (150 bucks max and about 2.5 hours insall). Then up the boost and see how much boost you can do without blowing up. Should be real cool.

 

Well... lets just call it a experiment if it doesnt pop then itll show you can run a midpipe on stock ecu. As that post showed the guy was getting safe AF ratios when he did it. That and if it does pop ive been itching to upgrade to a bigger turbo. So whatever happens happens.
Now.. does anyone have any info on a good way to drill out those nipples???

 

LOL, Best topic title I have seen yet.

Really its not a good idea though. Your wallet wont be your friend anymore if you do.

 

should be with mp on, no porting. wg starts to open at 7-8 psi.
