I have an 03 base model with alsmost 70k on it. I plan on having this car for a while and racing it quit a bit. If in the future my vq decides to give up on me is the new hr a worth while possibility? I would love to be able to run in the 12's na and the new hr motor has a lot of potential.

Thanks in advance for any feedback

it does but a shop on here already dismantled someone's 07 HR motor from here and they said a swap would be near impossible due to different ECU connections and pins and a whole load of other stuff that's different, especially trying to control 2 throttle bodies and all that stuff. you're better off buying another 03-06 motor and building it up with a stroker kit on the side for when you're ready to swap it in.

Nope!!!!!!!! Forget about it, it will definitely not be worth it. You heard it here first.

Nothing good will come of that. Not a bad thought, but you would have more time and money involved in this project than it would ever be worth.

4.3L AEBS stroker kit, twin turbo NITROUS and fcon. car will own anything.

If you want to go NA, then swap an LSx in it. There is already a guy doing it.

Good luck with the AEBS kit. The only person I know that has used it is Injected Performance and they just switched to Brian Crower.

Go with the GTM stroker kit if anything.

The HR swap, while it sounds nice, is more than likely more expensive then putting a TT, ST or SC on your current VQ or possibly just as expensive as swapping out a motor like an LSx or a small block of some sort which is more capable with less money.

Noah is the one who is swapping in an LS engine.

Way more trouble then it's worth

Except for 1500whp twin turbo Vipers

If your gonna do a motorswap it has to be of significant measure to be worth it in cost and performance

An HR is hardly worth spending the ooodles of money it would take to make the swap work when a built short block and FI would probably cost near the same and be much more powerful

If your an NA guy wait for the Z to be in the 4.0L range and pumping out 390-420hp

Thats probably 4 years down the road so....in the mean time you can save up money for the swap or to just buy the new Z when it comes out with the twin intake manifold, variable lift on Intake AND exhaust cams, more cubes and an 82-8500rpm rev limit

From there you can build an even stonger NA beast worth the trouble for such a heavy car

The DE just doesnt possess the block strength the future VQ will have as well as the head flow.....even a cosworth head wont flow as much as a stock VQ37 simply because of cam choices....the variable lift will make much more agressive cam profiles available for high rpm life......that kind of cam isnt a reality for a street VQ right now....

You will do what you want but being partial to NA for a LONG time I have seen this in the Honda camp.....guys would spend 8-10 to make 250-270whp from a 2.0L .....pistons,cams, headwork, custom header, etc....only to come up short on power....then came the deckplates and 2.2L combos that pushed power up a little higher but ultimately the new K series came out with roller rockers, timing chains, stronger blocks and a better VTEC system.....if NA power is you goal how could you argue with 270-300whp from street setups

The biggest factor in all of this is cost of course....the HR is $$$ right now....a built short block not nearly as much....you could make more power than a bolt on HR with a built short block DE I would imagine but if you dont hit your target you may still build another in the future at an even higher total cost

At this point many guys abandon NA all together saying its too expensive....but on the flipside NA is tough ....almost gratifying tough....when you make big NA numbers people know you had to research and test and learn along the way. In the process you pave the way for other guys to go big NA

If you do this for the love of tinkering NA I think garners more scientists if you will....the FI stuff....the horsepower freaks....the go big or go home crowd

Neither is better but just different and ultimately similar on many levels.....with NA parts selection and design play a huge role in overall power output... you can make a few bad choices with FI and just end up with some small restrictions....with NA everything has to work in concert to squeeze every last pony out

Also the character of NA vs Turbo tuning.....the sound differences....the motors response....power delivery.....the raw immediate light switch with NA....the huge kick from a large turbo and sheer power at extended WOT

4-500whp NA is a beast and so is 8-1000whp.....turbo will always make more overall hp but depending on what your doing that may not be your goal so think about that

Plus I think the FI guys have more to monitor relative to NA guys.....boost, EGT's etc...not that FI is less reliable just that more can go wrong if you dont maintain things properly is all

whp to whp....I think NA is better.....***** out....turbo will cram more air than nature ever could

But I would love to hear an 85-9000rpm VQ....ITB's....equal length long tube headers, duals with X pipe....someday

thanks for the replies.....lsx is probly expensive as well.....any ballpark figures as far as price goes for and lsx swap?

its not impossible, but there are better options.

It would require custom wire harness or standalone management. It's deff not a drop in swap.

IMO it would probably be cheaper and more cost effective to go with a GTM 4.2L stroker built short block. Granted it is $9,000, but it comes fully assembled and puts out some NASTY torque.

ehh don't get discouraged, GIVE IT TIME...the HR barely just came out and maybe a first glance it seems not to be worth it, I guarantee that about a year or so from now it will START becoming a very common swap/swap of choice for vq to vq. This is always how it starts in the beginning....

The HR will be replaced very soon by the 3.7.

^^Ya the 3.7 will be worth waiting for. I got a 2007 z y-pipe (post 11/07)--anyone know if this will bolt on to my revup w/out modification?

A 302 wouldn't be a bad idea either with just the stock ECU from the mustang. With the right fuel system and some A/F tuning they can see good number with a built motor for a decent price.
