LOL, you guys crack me up. whats so funny is only you guys would try to argue a matter of opinion. You really must have no lives. And its Not just you but there are so many people on here and hella people on AZ do it too, that have to try to prove someone wrong any chance they get on the internet no less. But it really cracks me up you guys are tring to debate an opinion. My car is the best color because I say so, i bought exactly what I wanted. If Imola was the best, then I would of bought Imola. I bought exactly what I wanted. a AWD V6 Manual. and I bought it in blue, I found a ocean blue B6 USP but it was far away and it cost more at the time I would of needed a loan at the time and I liked the denim blue better and got lucky it was only an hour away from where I lived. and I chose denim over ocean and the nogoro B5 because I liked it the most. So much for discussing mods for the 3.0…
- All depends on the delivery system.
- Yes
With the same Vortech that the 4.2 uses. Because isn’t that the one you recommended would be best? so if you say so then thats what I would want.
Also can you estimate what you think the gains would be??
way sicker
I don’t think he is saying that.
On a b67 s4 for example you can make 400-450 whp pretty safely…but you can make 375 whp and kill the motor if you do a poor job of power delivery.
Same on the B5 S4…the JHM rs6r turbos make enough power to make 600 whp which will require a built motor … Bit if you manage power delivery you can run them safely on a car with stock motor.
So peak power doesn’t matter when it comes to safety. Faw asked what peak power the engine can handle…and that totally depends on how you go about it.
Are you telling him this, or asking?
The Vortech supercharger used in the B6/7 S4 and RS4 kits can give the 3.0 more CFM than it will ever need. If your this serious about performance and potential, give JHM a call and see if they have some options for you. I hope that you have $15k laying around though.
Does anyone know the limits of the 3.0? You can’t just estimate the potential horsepower gains without knowing what the motor can handle because like I mentioned the Vortech will probably be more than the motor will ever need.
Both, I think Count said one top that it was best to use the same Vortech that the 4.2 used. Are you saying that 15 kit for the price of the kit and labor?
I would too like to know what the 3.0 can handle in its stock form. is there any technical or mathamatical way to figure it out or do you just have to push one to its limits till it breaks to find out??
Can you estimate it by how much the S4 and the 1.8? and the 2.7? and just kinda find the mean value of all those and have a ball park for where the 3.0 might land?
$15k plus assuming you do it right…engine/supercharger
I’m sure you could test 3.0 rods and make a mathematical GUESS overall. But then your playing with fire because parts weaken and deteriorate at a certain rate. How many miles do you have? 100k plus? See where I’m going with that. It’s really hard to just put a number on it.
Also, rods and pistons aren’t the only concern. You have too look at the valvetrain, piston rings…lots of things change with the addition of FI.
this hypothetical discussion is a bit silly.
JHM will sell you NOTHING until they have installed this on keaton’s car, and driven it for a year at least, testing, revising etc. Since I didn’t hear his car whistling when I was there in December, that puts you out to at least 2015 before there is a possibility JHM will put this in a customer’s hands.
Just sit tight or look elsewhere if you want monster power from a 3.0. If you want some nice bolt on mods, JHM is seemingly the place to be.
Has anyone thought that perhaps building the motor isn’t as hard as you think? My local guy who has a track record of fast reliable racecars suggested that maybe all thats needed on the 3.0 is doing an ARP rod bolt kit. Just put the car in the air and pull the pan and swap em and run a charger. I mean sure, you may need more for a lot of boost but if your doing a stage 1 maybe thats all you need. I was also thinking maybe swapping manifolds and turbos from a 2.7 and then JHM makes up sort of a “you supply turboes and manis and we supply hardware and tune.” Type kit… ?
By all means, trust those NA motor pistons originally specced on a 180 hp car with boost. Let’s see how it goes. Must be easy right?
What’s the cost of trying it the easy/cheap way…? Motor, rod kit, engine pull/teardown/reinstall.
And if it goes horribly wrong…start over. Easy!
He thinks…
MAYBE
…because he has built track cars with records.
MAYBE that is all you need
MAYBE…
That is all I saw, not anything promising. JHM will do it right, if they even do it. Go try it out and report back…buy an extra motor before you do it though.
You can try that and only run a few PSI. But the cost of setting up a supercharger kit and getting it to run right with only a few pounds just isn’t worth it. Power-Per-Dollar ratio just isn’t there.
You guys should check out scaudi for some info on running FI on this engine. I had some posts on there inquiring about buying pieces of their kit and having a local shop do a custom tune. This was right before talking to JHM about starting a 3.0 program… I think the local shop steered me toward JHM as they were leery about the history of the pes kit.
Wow, that forum is a ghost town it looks like.
Haha yup, not too many people on it anymore. I had a bunch of pm’s when I logged in asking about JHM from last year haha. Some good historical info though. There’s a couple guys who went pretty far with their PES setups on the 2.8 v6.
Haha nice. Who was doing the tuning for them?
For the pes kits? I think the only stable ones from an OTS tune were from GIAC, but then they went their separate ways. Everything else was custom, usually using eurodyne.
Ohh gotcha!
Well I know that we were talking about getting the PES kit and making our own tune, he said with that setup with such low boost that rod bolts would be somewhat safe. Not trying to tell you guys that your going to slap turboes on there and go 15 PSI and be good to go on stock internals. I am not an idiot and dont really apreciate the shit talk. But do what you want.
On the otherhand, I know that I am not going to modify or dump money into my 3.0 unless someone reputable like JHM make a kit/tune. If they dont I will drop a V8 into it and set it up like an S4. Or I wont even bother and go back to the old 70’s Datsuns again.
