There goes my turbo.

My god man... Don't fool around. :shock: Pull those pistons out of there right away. You can't compensate for pistons that are WRONG. Get the right ones. Heck, go back to using stock pistons. They work fine at lower boost levels. I'm running 10psi on mine with NO problems.

<div class='quotetop'>QUOTE(AK1)</div><div class='quotemain'>If your FPR is not referencing boost and increasing pressure say on a 1:1 ratio under boost conditions then you're just going to be running lean with all that air and not matching fuel quantity. Â*
</div>FWIW, the stock fuel pressure regulator on the 4G64 Spyder engine is a 1:1 rising rate unit. I did not have to change it for my turbo install. It works great. Base pressure is also higher than a turbo model car. It's 48 instead of 42. I get 60psi fuel pressure at 10psi boost. It would fit a galant fuel rail, if you wanted to get one. They are under $50 brand new from the dealership (part number MD322829).

thanks Curt for your input, i appraciate that.
i will keep you guys updated as far as my car....
i send the pictures (friday evening) to AK1 with my stickingo out pistons, but i didn't get no respond yet (saturday afternoon). I am wiating till they contact me or Tony, and then we will go from there...

[AK1]

Martin,

I have emailed JE the pictures on your behalf. That is what they have requested before they take any action on the pistons. Tony(From JE) will call me back ASAP when he decides what the best course of action will be.

My own opinion is that JE didn't set the wrist pins deep enough but that's my personal guess. Regardless, as soon as JE gets back to us we will let u know. Do NOT attempt to use a bigger head gasket to fix the problem. When he put the first piston in, he should have cranked it to check before putting in the other 3. But that's besides the point. Hang in there, we'll let u know whatever we find out asap.

[DJ Galant]

Thank U Andrew for letting me know what's up.
I am waiting till you guys contact me...
Thanks again...
Martin

[DJ Galant]

still waiting andrew.. for u to contact me

To be honest I didn't read through every post but here is some info for anyone putting a turbo kit on any car.

(A) It doens't matter how little you boost a car you should always look to feed some extra fuel somewhere. Even if it is as little as a rising rate fpr unit and an extra injector or something.

Your failure problems are purely and simply a cause of running lean. No other reason. At 4 psi it was probably running lean enough to do it slowly over time but not quite enough to do it all at once.

I woudl suggest for anyone doing a turbo upgrade to do the min of

(A) Larger injectors - RPW has 300cc injectors direct bolt in replacement with no resistance problems etc

( Rising Rate FPR unit - set fuel pressure to at least 45 psi from standard 38 psi

© Piggy back computer to recalibrate fuel and IGNITION Curves if possible as well.

Colder spark plugs one heat range are also a definite must do.

New Uptade about My 4g64T:
New pistons are waiting for me in Kentucky (thanks to Andrew), so i
should have them here in Las Vegas next week.
I am going to send bad JE Pistons on Monday to Kentucky, and as soon as they get it, they will send me the new JE Pisons.....
Can't wait till that day...


I GOT A QUESTION FOR THOSE WHO KNOW:

I was just curius if you know if I can install 1 gen eagle talon "big"
connecting rods. I have set of 4 sitting at home, and since I don't have the
money for eagle or crower rods, I thought maybe those would work instead of my
stock rods. Maybe the machine shop can shave them a little and I can get
different bearing or something (it is just my common sense thinking).
I am curius also, if you know what measurments are 4g64 rods,and if you know
how much hp they are able to sustain.

[Spyder4G64t]

[bump]

So, how is the project going? Any updates?

[DJ Galant]

well, there is a good news...
i send the bad pistons back to KY, and on friday i got in mail the good ones.
So, i took it to the shop on saturday...and now i gotta wait till everything has to be re-installed. What sucks about the whole thing is that machine shops here in Vegas seem to take their sweet time to get the shit done. I was waiting a week to disconect the rods from the pistons, and now I hope it won't take that long to connect them back....
Besides that, my 310cc fuel injecors, safc, dual boost contoller, cold spark plugs, gauges (EGT and air/fuel ratio) and whole bunch of other shit needs to be installed as well.
Hope to get my car back ASAP....
I'll keep you uptated....

[Kwiksix]

I feel your pain man!
Just got my car back wed.
Had my motor apart,bad piston but it was worth the wait.
It made me love the car even more than I did.

[DJ Galant]

hey Kwiksix
i am curius what kind of turbo do u have.....
which piston was bad?
what kind of turbo do you have?
what kind of piston did u install (new one)?
did u changet hem ALL or u just replaced the bad one?

[Kwiksix]

Did you get my pm.

[DJ Galant]

yep folks, it took about 3 months to get my g-ride out of the shop....
car started up with no problems after new set of forged JE pistons was installed. We changed some pipings here and there, EGT is hooked up, so is mine SAFC. Still waiting for bigger injectors, and my cold spark plugs have arrived today.
So far no problems, I check on the oil and water evreyday, just to be on the safe side. It is great to have my car back. So much of the wait can put you down, and I don't wish that to anyone on this board...
I will keep u uptaded how evrything goes, right now I am "breaking" in the pistons.
Probably in two weeks from now, I will take the car to the dyno to see the numbers at the wheels. I will see some of you at the LAs Vegas meeting....Take care..

Good job on the Ride bro, hope everything works out for you from now on.. can hardly wait to see the numbers when u get the dyno test.

[DJ Galant]

bigger injectors (denso 550cc) are installed....
the car is being tuned now with my safc....
evrything is working properly...I satrted to boost the mo-fo, too. No problems so far....
I love it....
It was all worthed the wait.

[DJ Galant]

my galant was running so beatutiful today at the 2.7-up rpm range, with open exhaust.........though i have to admitt - my agressor is not tunedf right in the 900 to 2700 rpm range. It hassitates, has some idle problem - due to improper tuning and open exhaust....
i will try to tune it right (well - not me - tony will) asap.
i think i am running too rich cuz when we were tuning it - the same was happening in th higher rpm range, though when we were at the freeway we got the right settings......but we forgot about the low rmp range.....
Love the turbo though......

[Moosh]

Hey. How is your car doing? Did you ever take it to a dyno?

Moosh

[DJ Galant]

is doing good...though i am on stage where we will do some serious tuning...cuz i am untuned for now..Dyno with the hot engine was 140 whp at 5.5 psi (low compression pistons).
Dyno guy says 5 hours of tuning will bring it up to 200s...
Cost of that operation 5*$150 an hour = $750 plus other fees.
Still collecting the mula...
do a search cuz i did a faq page too....

Good luck on the dyno and gettin the dough together i got my fingers crossed for ya..
