5 speed swap, q45

[elwesso]

Lets get back on track here gentlemen!!!!!

Thanks

Ok

The bottom line is that if you want a 5 speed in a Q it will simply require funds. Anything is possible once you have the financial backing. A couple of grand and a couple of reputable shops for fabrication will get you far. It simply becomes an issue of end results being worth the hassle. New cars are coming with 5 speeds because they realize that the car buyers want more. Now horsepower is becoming a big debate to car dealers. Just look at the neon and the focus. They didnt start out as power rockets but since the fast and furious craze it has become a front burner issue.

The Q is fast as it is. If you want more performance out of it look at what is available now. I am sure 10 years ago no one thought there would be optional gearing or intake's or anything for this car. If you want faster then get a true sports car. If you are just looking for something to do then fine put up the dough to get up and go!!!!!!!!!!! :ylsuper

I'm just still trying to figure out what a 287 is... Is that some american V8 engine? Why's he say 302/305? That's like choosing the tofu from each of two brands. Want a badass high hp small block ford, how about a 351C 4V. Also, a 305 chevy will always be lame because you can't fit decent size valves in its small cylinders. I think GM did a fine job with the Gen III small block. It puts out good power, is low cost, and lasts quite well. It would be better with 4 valve pentroof heads and variable valve timing, but that's $$$. The new hemi doesn't have hemispherical chambers like the old hemi. Just marketing. Thankfully it isn't a real hemi as it would never pass emissions. Even in it's current "semi-hemi" form it will have issues with emissions in a few years. As for the 5 speed, cool idea but not easy. I don't view the Q as a sports car. It's just a strong family sedan. Just my smidge of opinion.

That was awesome.....bravo!!

The Cleveland was a great motor, but, there arn't many parts made for it. I would personally take a 351 Windsor or Modified, insted of the Cleveland.

Wasn't there someone that put a 350 in the Q? Was he a Nico member? aNY THREADS ABOUT IT?

Very true.

Tune in next week for the conclusion of "Drivers who dislike the car they drive, yet sign up to an owner's club as a medium to display their anger, venting on serious members all the while wishing they were instead on a Mopar thread."

Did I say that I didn't like the Q? I just don't like that when things do go wrong,which is often, I'm always looking at a minimum of $500. Thats when I do the work myself. If I take it to a shopo, it's $1000 minimun.

[PoorManQ45]

They brought back the Hemi because of the mystique. It's a marketing ploy. A hemispherical combusion chamber is actually not the best design, but no one ever accused the American public of being all that educated about things automotive. I cringe when I see that ball-cap-wearing doofus on TV saying, "Yep - It's got a Hemi."

The Hemi used to be a great engine. It put out good HP and massive amounts of Torque. What they brought back is a watered down version of the legion.BTW, I just used the Hemi as an example of a current pushrod engine.

[quote=" AZhitman The GM 350 is a great powertrain, but if it had an aluminum block, variable valve timing and 4v per cylinder, it'd be REALLY impressive. Maybe 600 hp?

Ford is finally starting to get the picture (2.3 Zetec in place of the 2.4 I-four and dropping the 5.0 in favor of the 4.6 modular).

BTW, let's get your 92 whipped back into shape - What's going on with it that's so frustrating?

THAT'S what NICO is here for! [/quote]Variable Valve timing is not that great. It does add a little horsepower. But, I could get that same amount of HP increase, probably more, out of the motor if I upgraded to a cam with Longer duration, higher lift, stiffer valve springs. I could get about 50HP on most motors. And that would be without going to radical. So, it would still have a good idle.

About the 5.0 vs. 4.6. Hehe. there's no replacement for displacement, except boost. Modified 5.0 vs. modified 4.6, would result in a win for the 5.0.

I just had an idea to modify the VH. When I go to look for parts, I'm looking at about $15k. Everything has to be custom built. For that price, I could swap in a really badass 351W or a 454. Thats what is getting me frustrated. I do admit, that the first gen Qs were/are great, even stock. I just want more.

"How much is enough? Just a little bit more.?

[quote=" AZhitman Z06? Big deal. 26% more displacement making 30% more horsepower than a VH. And at 100K, I can PROMISE you it'll have some notable internal wear. And it won't see 200K without some intervention.[/quote]Compare the exterior dimensions of the 5.7 to the VH. It would seem that the VH is larger, even though it displaces less volume in the cylinders. Pushrod engines save space. The cam and pushrods are located between the cylinder banks, instead of on top of the heads. On most engines, including the VH, the area between the cylinder banks goes unused. This creates an unnecessarily large angle V.

Even though it may appear that I don't like/hate my 92 Q45, that is totally untrue, I love it. It's just that I am giving respect to American Muscle.

I'm just still trying to figure out what a 287 is...

Dude isnt that the Q displacement

I had a 5.0 and I must say in terms of power the Q got it beat overall. But in terms of maintainance it is cheaper but remeber the 5.0 is much simpler and barbaric.

Sure a built up mustang is faster but its been done. Sure the same can go for an sc, just have a special head gasket fund. The 4.6 isnt all that just a good cab motor. Good for supercharging though.

[HeavyDuty]

Sigh,

Not to be cliche`, but fellas, it's all good, 383 windsor, RB26DETT, GTI-R DET, Ram Jet 502, etc, etc

Just to let you know I'm not hating from either camp.

Used to be Ford vs Chev vs Mopar, now it's just two camps;

"This here corner is for 'Merican Ayern, the Ferrin guys hang out down the street."

351 Sportsman block stroked to 383ci, forged internals, Vortech T-Trim.

Sexy engines all around

[PalmerWMD]

Sorryfor the hi-jack:

I destroyed an early 90's Mustang 5.0 with IHE and bore 30 over, from a roll at 40 mph.

By the time I shut it down around 110+ mph he was way back..

With a Nissan 2.0L 4 cylinder.

Fred..

[buttons]

DAMN. Manuals aren't worth the hassle.

IF they were I would basically want a T56 bolted to an LS2.. drop both in. :-P

[AZhitman]

^ Not bad for a n00b - I like the way this guy thinks!

There's a 427-powered 90-93 Q floating around somewhere....

[maxnix]

Bottom line is, every one talks about how easy it would be to put a manual transmission on the VH45DE in the G50, but there is no documented evidence of anyone actually achieving it.

One reason Q45tech's posts are so worthwhile; he gives valuable data on things he has actually done, not mere nocturnal speculations. Woulda, coulda, shoulda mean nothing compared to I did and this is what happened, and here is its history.

[elwesso]

BRian, if you look in the Q45 ENGINE IN A SILVIA thread, they hooked up a Z32 transmission to a VH41 (IIRC?)

IMHO a level 10 transmission with lots of mods (or every possible) is more worthwhile than anything.. Hell, throw in a 4.08 for good measure..

[IvoryJ30t]

what i dont get about you guys wanting to do a 5 speed conversion, is why you wouldnt want the nissan transmission?

the Z32 TT flywheel bolts up to the VH, which means you dont need a custom flywheel or clutch.

its gonna be a pain to get the adapter plate made, because it needs to be accurate, or your gonna be trashing input bearings.

the shifter modification would be the least of worries.

might need a new driveshaft yoke.

[450zxtt]

i have a z32 manual hooked up to a vh45de in my 1993 z32.i see a lot of discussion on this site about boosting this engine and the possibilities of adding a 5-speed.discussion is good,but go ahead and do some of these projects.some teaser shots:www.freewebs.com/axepower/many of you discussing this subject have the skills-just go for it,dont let your ideas end in these threads...

So where are the pictures?

[PoorManQ45]

What!!!! Can you post pictures?

Where did you get the adapter plate made?

How much did the whole thing cost?

Did the bellhousing have to be modified?

[1qckser]

WOW

[IvoryJ30t]

i will once i have the time and money.

actually, i have the time, ive just been real lazy for about a year now. ive only been working 4 or 5 hours a day, if that.

i saw the picture, and i cant believe you got that mofo to fit. nice job.

i think you set it up like my plan B. since a top to bottom flow ic wouldnt be that efficient, i was figuring that i would have one charge pipe crossover behind the oil pan, infront of the crossmember [or behind depending on space] and y pipe into the other charge pipe. then through a side to side FMIC, and up to the throttle body.

what did you do about motor mounts? did the vh drop onto the vg's isolators/crossmember?

if you could give me just that information, i would appreciate it. i want to slap that in a J30 which uses the VG30DE, so the mounting would be almost identicle.

the J30 has more room between the strut towers than the z32, so you just made my day by showing me that it will definately fit!!

once again, nice job!!

[PoorManQ45]

For the car in those pictures:

Did they use the automatic transmission, or did they fit a manual to it?

[1qckser]

Read his post

[HeavyDuty]

That's awesome!!!!!!!!!!!!!

I guess it's obvious it won't fit under a stock hood, but aside from that minor detail, killer swap.

I bet that thing sounds like all hell breaking loose under boost.

Congrats!

[maxnix]

Truly amazing! Wish we could see all the plumbing and the bell housing.

I wonder if the VH45DE is that much heavier than the VG30DE cast iron block? It might still handle resonably well.

[AZhitman]

50 lbs heavier according to my math.

Irrelevant, basically.

God God, what i wouldn't give to spend a couple hours alone in a garage with that....

[elwesso]

Sorry Greg, but I just *couldnt resist*
