Well, I dont think that anyone should go F/I without building. Perfect example is that my boost controller had something wrong with it and was boosting like 18 pounds.....I have a boost gauge but I did not realize what was wrong cause when I looked at the gauge it said 7PSI....where it was supposed to be. I guess I was not looking at the right time. Bottom line you put the kit on a stock block and dont notice that....BOOM!!
Just build your motor before you go FI. No worries then about mileage....for a while anyways.
Just my .02

 

well overboosting on a built block is also not good.

 

I understand that...however on a stock block it is detrimental. I was not saying you can go around overboosting if you have a built motor, but if you do it on a stock block things go bad quickly.

 

Crank pulley? bad brand? damaged? or just shouldn't have a lighter CR when FI? Please explain...

 

That and the fact that you've had great success with your kit so far on a completely stock engine.

 

Most people that go FI are on a stock block. If done correctly it can be very safe. I already had an 04 with FI without any major issues and now am looking to do the same on my 06. Just wanted to see where people are at with this JWT kit. Of course I will be making some of my own adjustments to this kit as I think it is lacking in a couple of areas for a proper 400whp car.

 

Is that really what you got from my remark? Thats a strange accusation..



I never said anything of that nature. Your opinion conflicts with 90% of the FI Z's out there. If setup properly...a stock block can be reliable...assuming you don't push the hp limits

 

nope stock pully.....changed the belts, got her started again...I was happy for like 10 miles til BAM...oil everywhere....the crank must have been bent well....everything is for sale including a stock motor i ordered in case the 383 Z06 motor doesn't work out....

 

I was in the middle of a couple of things and missed the statement above your remark about what you liked to see. I thought you were referring to the one above that said he had an issue.

As for my opinion about going FI and building....I know most people do not build. I know you can be fine and safe on a stock block to a point. I think when you build you hedge your bet. To me it is sort of like betting on who is going to win the superbowl at the beginning of the season vs. right before the game starts. There is a lot better chance getting it right by building the engine. Less chance of throwing your money away because something goes wrong with what your plans were. That is my point, and I think that most tuners would rather build the engine than do a stock block.

That is all I am saying not that it cant be done as safely as possible...just that I feel it is better to spend a little more up front and not have to spend as much down the line....hopefully.

 

There goes a thread.

I agree that a built block and twin will be better off. But not all can go all at once. People do things in portions. Don't bit too much off so you have sell the car after you get it done...

And Gus said it overboost on a built block won't be good. Sure it can prob. handle a little more but say your set at 18psi and then you BC goes to 25psi?? Same thing, right??

When I go FI I won't be building right off the bat unless I convince the 80 million dollar truck driver I am his son

 

OMG we're BROTHERS!!!!!!!!

 

You guys are too much.....I understand that people will not always do it all at once. And I am not sitting on a high horse saying this either....you basically agree with my point if you are going to build. Not trying to start something just stating my opinion.

 

Yes, building probably leads to 0 blown engines--but then that's why this thread asks for problems w/o builds--so we can see how reliable these turbo kits are w/o builds. Why musty you built engine guys continue to hijack this thread. This thread is not for you--it's not for you--it's not for you! It's for those who want to see how reliable a JWT TT kit is without a build.

Starting a thread about the reliability of the JWT TT is like trying to discuss religion or politics; you better be ready for the responses from the JWT "True Believers".

 

You know I do not understand why there is so much negativity on these forums. Just because there is a thread about a non-built JWT reliability there is no reason why someone with a built motor or someone who thinks the motor should be built cant chime in. Believe me I am not trying to be negative or "hijack" this thread, but everyone can and should post their thoughts on different threads.
I am continually amazed at how many people rant and rave about someones post. If you take it and put it into your thought process about what you are doing then you will make a more intelligent decision about what route you want to take.
Just because you may not want to know about built engines on this thread someone that is new may not know the difference and he/she would have had their question answered.

As for your question though, from what I know it is not the kit that is a problem on any stock block it is the installation and the tune that makes it reliable. So if you go this route make sure you go to a shop that knows what they are doing and can give you the best tune.

 

Thanks but I don't need advice on what is needed for a proper FI conversion. If I or anyone else did there would've been another thread for it (and there are a million of them BTW). The kit is labeled as a bolt on kit for a stock block and that was the whole purpose of the thread...to see how those are running after having had ample time to log on some miles. If you have a built engine and wish to share your experiences that would still be fine...but like I said earlier I don't need your advice. Thanks to everyone who posted what I asked for...whether you had a built motor or not. There goes another wasted thread that had some potential....

I don't understand...we've had plenty of threads like this for all other FI kits, but this JWT thread poses some sort of an issue that I'll never understand.

 

You are the one that made it an issue....if you would have said thanks for the input, but I need some more people to speak up about non built blocks then maybe you would have gotten somewhere. As far as I know most people who have the JWT kit are building the engine. That is from my experience. At least here is So Cal the ones that have the kit build.
Are you staying away from a build because of budget or do you just not want to build? Just curious....

 

The point of this thread is to see how well the kit is holding up. Nothing more....forget about me and what my goals are.

If you absolutely must know, I simply do not want to build...just looking for a modest power increase, which is supposed to be what the JWT kit provides. In all honesty the car will not be with me long enough to justify a built engine and I am not looking for monstrous power outputs. Just to give you an idea..I've had 5 cars in 2 years if that is any indication as to how I go through cars.....I am just looking for a kit to get through to next year before I trade in for an 09.

 

Well it is a good thread and question but I think you started it off badly by putting the statement below in your request and getting people in the defensive, it would have happened with a Greddy or APS thread.
