ouch... on over 1 hundred thousand miles...

 

ill let you know what we find, if theres a hole, ill make sure you get the pics.

 

First off as others have stated a compression test and leak down should have been done when you decided to boost a car with over 100,000 miles on it. Second you added a boost controller to the mix but I would be curious if you hooked up the boost signal lines to the wastegate correctly. I sincerely doubt the reflash has anything to do with this. The reflash doesn't control boost its only tuned for 8 PSI. I'm not saying its the end all be all solution but you can't blame the tune for this one. A boost controller, improperlly hooked up boost signal lines, no AFR gauge, and a motor with over 100,000 miles are all a recipe for disaster. Hell if I was boosting a motor with over 100,000 miles with so much as a snorkel I would get a leakdown and compression test.

 

damn dude!!! what ahppened? did someone install the boost reference signal to the wategate into the wrong port on the wastegate. doing so would hold the wastegate shut, rather than opening it!

 

Im running the reflash, apexi exhaust, motodyne spacer and hitting 8.5 consistently with no problems. Wideband is always showing sub 11's afr at full boost.
I guess the 1800.00 to have a professional shop install the kit was well worth it!

 

Damn, sorry to hear. Good luck getting it back together.

 

ive already said im not here to bash on TN, i like the kit, and still recommend it, its just that you need all of the essential elements along with the kit (right gauges, tuning, etc.) and ill do it right the second time for sure.

 

I'd agree, but I don't think it's directly a tuning issue per say. It could have been many issues. The key to being "safe" with the reflash is to verify the system is running properly before running the car hard. The reflash works... you just have to be careful to verify it's working properly first and foremost.

If you downloaded the base map from TurboXS and took the car out and hit full boost without verification, you wouldn't blame it on the UTEC.

 

sounds like no wastegate line. this is one of two things, tuning error or install error.


these motors have A LOT of room for playing around. it would be very very hard to blow a motor on wastegate springs alone on the TN kit.


next time around, please take it to a shop and have ti installed and/or tuned.

the reflash will work just fine on stock boost. not recommended for sure but it will "work"

 

Buy a new motor and do it again but make sure you get it tuned before you drive it hard.

 

should have went to performance factory. BTW JT this ride is so sick!!!

 

dude i doubt anything was wrong.. did you drive your car hard before the install? 100k on a motor is alot. esp to boost after you have beat on it for a while

 

I know PF is a good shop.. all your fanboyishness aside.. do you think someone is going to drive past MRC, FunctionTuned and Forged Performance just to bring their car to PF .. i mean.. be realistic for one second. I recommend people in FL to PF, but you are just getting outrageous now.

 

100K is not alot of miles. We are talking import engines. not domestic.
I would have done a comp and leakdown first though, but deff not too many miles.

 

wow no dyno Tune and 100K motor, thats a receipe for Disaster. Sorry bro to hear about it tho.

 

I agree. After 100k miles those connecting rods should be no weaker than after the initial break in. As long as the oil was changed throughout the life of the motor it should be no issue.

 

Except you have to keep in mind there are severe oil consumption issues on even some new VQ35s. I know of some 100,000 mile VQs locally that lose 1 quart a week. You can bet that if you boost a motor like that its not going to last a long time. Especially if the boost was set too high.

 

yes i would drive hard at times / drag on the highway / etc. before boosting it and had no problems.

im hoping and almost positive it was the tune / boost issue. was too careless to make sure EVERY step was completed and safe. ill make sure its fully tuned, all gauges hooked up and ready to go, and probably moderate engine build the 2nd time around.

 

With no offense to your friend: how many turbo installs and tunes had he done before he "helped" with your car??

 

I agree. Unless those things got some hot cycles and the bearings were shot from low oiling they shouldnt really be any weaker.

I will agree on the next post with the oil consumption though.
Did this thing ever burn oil? Low oil and scarred bearings will cause for much trouble eventually down the line.
I still think it was the tune or overboost though.
