Thread: Does anyone know more info about the HV3?

I'm pretty sure ZZP stopped making them, but do they really work? 30whp at 6k rpm?

yes, it really will give a n/a motor that kind of gains with the correct supporting parts.

whats the supporting mods? i cant pull up zzp's website it wont load =/

you wont get that much out of it without a downpipe and rockers. however, you will still notice a gain.

Well, I installed my HV3 last year without any other mods and it has made an obvious difference in top end power. However according to my butt dyno, I’d put it at ~10whp. Over a couple casual emails with ZZP, Turbo Tim recommend setting my shift points to 6K to get more out of the insert. I would totally believe 30whp with 1.9 rockers at 6K rpm.

well I'm getting a DP and resonator delete this week, then hopefully ordering the HV3. And I'll be getting an overkill pcm, because I hear not-good things about zzp's pcm's lol

I would but I'd rather just get a L67 outta the junkyard and drop it in.

^^Agreed. And save the money deleting the resonator too. I mean...unless you like your car to sound worse than a D-Series hatch.

Nothing wrong with ZZP PCM's.

I got mine for $40 though.

And honestly, why mod a GT? Unless you're going to boost it, pointless beyond belief.. no matter what anyone says.

I know, I really wanted a gtp but insurance would have been crazy, and I couldnt pass my car up. But part of me wants to see what kind of power I can get out of a N/A 3.8.....

You won't get any.

Yeah, i mean if i want a supercharged car, I'll just go out and buy a gtp but I like my car so I'll keep it. Tint and HIDs will be done by the end of this month. Exhaust work this week (if i keep the resonators, i'm ditching the cats) and rims farther down the road.

Why do any exhaust work? Leave it alone.. esp since it will sound worse more then anything.

Don't waste your money.

Well I gotta get a DP. N/A is 2.5 inch right? I just don't want anything to restrictive. And I deffinatly WONT put a flowmaster or anything like that on.

jezzzzeeee man its his car, if he wants to mod it so be it.


some people like to work with what they got. some people like to be diffrent.

i say go ahead and do what you want to

get a 3" downpipe for sure.
