Updated update

After JBP continued discussions with a Garrett representative, the decision to go with the gt-40 turbo has been changed. The plan now is to use the gt28-76r turbo x2. Yes we are going with a twin turbo set up on the engine. I have been told this will be a very efficent way to run the engine and the power output of the turbo's will surpass my need allowing not to run the turbo's at peak out put. I am new to this concept so forgive me if this isn't the proper way of describing this (Matty )
The 2 turbo's have been ordered and the fabrication starts next week.







Okay so the last 24 hours have sucked a bit. First I get informed that Turbonetics just went through a personel change and the turbo they were supposed to send a month ago is not coming. If I want to go with them I have to start the sponsorship application all over again. @#%^&* was my response. Then I get told that the time factor for getting a twincharged setup was going to be along time due to the fabrication process then proper testing. Testing would be time consuming to discover if the effects would cause a failure on our blowers. More @#%^&*.
So, I talk with Mev at JBP and tell him to forget the supercharger and just turbo the darn thing. He is looking into which turbo to use, likely Garrett, and whether we can use a sequential setup (kind of twin turbo) so a smaller turbo can help the large turbo get up to speed.
There is a sadness to giving up the twincharged plan. This is offset by the much more simpler task of turboing. Tuning will be easier and no unknown issues with the supercharger. I know lots of people will say "I told you to just go turbo" but I am not really in the mood for that today. I could continue to pursue the twincharged project but consider that I have been with out my car for 4 months already. I don't want another 2-4 months to pass. Enough is enough.
My hp #'s is what matters the most in the end and I have said before that if twincharged didn't produce the right numbers I would go straight turbo. I am sorry I won't get to see how twincharged works. To make matters a bit sadder, I heard a BOV on my nephews Skyline and I don't like the sound (I'm old guys) I will truly miss the sound of my supercharger.
Once I have a bit more info on the turbo setup I will post that as well, which should be later today or tomorrow.

Update

For the turbo we have chosen to go with the Garrett gt-40 for the big turbo and the smaller one will be picked tomorrow. The calculations are that with the gt-40 I will get my 2.0 liter displacement equivalent to 6.55 liters. This means going to a much larger fuel pump (Holley) and a inline fuel regulator, as well as I will be putting braided fuel lines.
Now that this is the chosen path, JBP will be starting the fabrication of a throttle body, adapter plates and a custom turbo header which will likely help some of you other guys who are planning to go turbo. When I know more I will let you know too.

 

yer car will still be a beast no matter what route you take

 

Well, on the bright side, you will be able to make more power just going with the turbo by itself. Twin Charging is a cool idea but it doesn't make a lot of sence when you really think about it. Your going to get to a point where the blower is just going to impeed airflow and create more unwanted heat. Best of luck with the new plan. Can't wait to see it on the strip in April/May

P.S. You can get BOV's that aren't really loud

 

Sorry to hear that. Either way it's all good. You'll have a nasty Balt at some point. What I don't understand is how a few other people have twincgarged. Badg1rl's car is twincharged. I don't know how well it runs and or if it's just for looks but other people have done it. Good luck with everything bro.

 

That is the whole point so that makes this a sound decsion.
Well that is good to know, now i feel better.
From what I heard from Donna, twincharged and Keith Losier was than none of them were tuned 100% yet. This will work but I won't be one of the ones to help prove this technology.
The good thing is once I get to the track all this will be for gotten in a 1/4 mile.

 

Well good luck with your new project. If you want I'll lend you a box of kleenex for the sound that cars going to be making...lol

 

BIG Turbo nuff said. See if a GT28r can squeze back there. F a smaller turbo for spool time. we got rev's it'll spool sooner or later. Make a highway queen thats what i say makes for better video's. Two manifolds, some piping an intercooler and a tune later you'll be beasting.......

 

Sorry to hear your ditching the twin-charge.

On the bright side, your car will still be a beast just going turbo. I was really interested in seeing how your project unfolded as I was also interested in doing a twin-charge setup next summer, now I might just max out the SC or also go TC. I wonder if the tuning issue is part of the reason that we haven't heard anything from Hahn lately regarding their twin-charge setup.

Good luck with your SS-T ? or SS/TC ?

 

any one know how donnas car actually runs? i dont think if eavin heard of her running it really. i want to know what it does in the 1/4 and how it just drives period. also remember that RL that was twincharged and for sale back in the day...any one got info from him on how he did his? i saw a vid of it when it was for sale

 

Rod why dont you go with(forget name) turbo shop in Langley,CAr meet??

 

Well, at least you at still one step ahead of me. You can tune your ECM. I can't, and apparently won't be able to until next year at the soonest. To be honest, I'm surprised at that no one has a working turbo-only LSJ yet.

 

You mean Kinetic Motorsport and they upset me when they never got back to me when I originally asked them about working on my car.

So the news I have read about the 2.2 tunes is false? That does really suck because you have been ready to turbo your built engine for way toooooo long

 

Halfcent there are actually a couple of redlines running a working turbo on LSJs. ill be next.

 

TRAITER!!!

 

If I were to predict someone to go full stand alone on a 2.2, I think I know who it would be.

 

I still love you though..

 

Hey Victory have you not looked into a whipple or some other kind of screw type supercharger to try and get the #'s you want.

 

Well , brutha Im sorry to hear about your problems . It really suck when ya have a plan you wanna stick too and situations beyond your means wreak havok on it all . I know how ya feel . Were building my friends 96 Z28 currently . Started in May , and it was supposed to be done and running by the 1st 1/2 of July . The engine took over a month longer than promised , 3 Big stuff3 PCM's later we finally get a PCM that will provide a ignition signal to the LT1 ignition , MSD boost-a-pump on national back order . And now currently everything is done , but it sits waiting and waiting and waiting for the seemingly un-attainable 90 lb/hr injectors from racetronix ....which nobody stocks we found out . You jus have to order them and wait . I feel your pain

So hang in there man ......I really am looking forward to seeing your SS run , its gonna showing alot of stuff we , amazingly ....havent seen on a street driven SS yet . I know it kinda screws your original idea's of wanting a successful twincharge set-up , but once it done , your driving it , racing it and working on it .....I think youll be glad you went with a single turbo .

Good luck to ya

 

well atleast if you turbo it, you basically pioneer the turbo process for these cars and alot of people will follow your set up.

You can Call it the Victory Turbo Kit. lol

sorry about the news though, i feel for ya!

 

What have you read? Tune Time is advertising a single flash tune for a stock engine still normally aspirated. I emailed them asking if they can make a 2 BAR MAP OS and never heard back from them. HP Tuners won't have anything this year.

For me to go stand alone would be a HUGE project. The whole goal of this car was to maintain a completely functional stock car with turbo performance. Due to the intergration of other systems into the ECM like the power steering, it would be hard to simply by-pass the ECM's engine functions and still get to operate my steering (among other things). I can do stand alone fuel and ignition using MSD or AEM products. Trust me, I've looked. But I can't find a way to keep the stock ECM in the loop.

 

hey V, sorry to hear about the Twincharge mess n runaround,
maybe it would have been a neat intellectual exercise and quite a conversation piece, but like some have said, probably a nightmare to tune and keep running.

However, It will all blow over and be overshadowed once the new Turbocharged monster steps forth!

 

well sorry to hear it but im just hoping you get your setup done before i get mine lol

u can go your turbo route but ill take my supercharger.... it will be just fine for my daily driver...

plus i like the sound of the sc and the injen cai

good luck bud

 

Trust me all, I love the supercharger whine and I will miss it. I have already told JBP to get me the quietest bov there is because I don't care for the sound and if I can't have the whine of a SC then I will do without replacing it with a loud bov. Perhaps the company that makes the bov sounds for cars can make me a supercharger whine. Or maybe you cans can record me yours and I will play it on my mp3 with a speaker wired under the hood.
As for the turbo we have chosen to go with the Garrett gt-40 for the big turbo and the smaller one will be picked tomorrow. The calculations are that with the gt-40 I will get my 2.0 liter displacement increased to 6.55 liters.

I want a bad ass throttle body,on the bright side they are comming out with cams for the vvti 2.4

 

Thats good news. Who is "they"?
