Was pondering my options for motor stuff, (size, vrs power adders). Was looking at some turbo options. All real expensive stuff, Then I thougt what if I just hooked up a 75-100 shot of nitro? What mods to the motor Ya think Id need to not blow it up.
Pro's
I could keep my present carb setup and just have two seperate wet knozzles one for each side.
Can run normal when not "on it"
Might not have to change much on my present motor, maybe better heads and a counterweighted crank.
Con's
Gotta refill every once in a while.
easy to blow something up if something is not right (fuel pump lean ect)
Gotta open the bottle when you want it.
Whatcha all think.
Yes I want more power and I want a freeway flyer trans.
Winter projects are freeway trans engine of some sort rebuild the front beam as the intermittant clunk noise is starting to piss me off.

I assume you are talking about NOS, rather than the fuel.
I spent a summer with it once, and probably wouldn't do it again unless I somehow got into drag racing. Don't get me wrong...it IS addictive, and kind of expensive because it is so addictive. Kind of like driving crack cocaine. Ultimately, I used it to pass all sorts of big boy sports cars like 'Vettes and Mustangs on the highway with a four banger.
If you want that kind of thrill, I would use a turbo. It gets exciting too, especially when it comes on in corners, and ultimately will probably cost you less money over three years. Keep the boost sane, and they are a blast. Cams need to be picked out carefully, however. To work well, you have to open the exhaust really early and have lots of overlap.
I ran 19 pounds of boost on my Mustang SVO, which was great. Upgraded the injector pump and used injectors out of a supercharged Thunderbird SC.
I don't know what the best way to do it on a VW is, but I would think it probably would be a push-through carb in a box.

As Dave said, NOS is good for drag racing, and that is about it, whether on the track or the street, that is what it's for. A turbo will make you much happier in the long run, power on demand, still retain good mileage, very adaptable, always there. NOS to me makes no sense on the street, other than for what Dave did, to embarass the V-8 boys, which you can do with a turbo also, ask Ron P! Turbo'ing a VW is easy, and in some instances, can be a bolt-on affair, if you are just looking to add some power without going "all out" with a new build etc. You can turbo a stock 1600 and add power, you might not pick up 100 HP, but, with a small turbo, you CAN make boost. If you want the ultimate, build a purpose built 2332 turbo, that's the other side of the spectrum. Look into a Rajay kit, or check out Lowbugget.com, AJ Simms has lots of 1600 turbo options!

Well The turbo kits Ive seen are like 2000.00. Im watching a turbo motor right now on an auction and Ill see if I can pick it up cheap, but probably not. Nitrous kits are like 600.00. Id like to do the turbo, but maybe Ill fall back to the big bore option. we shall see. Im just looking at my otions right now. I really dont want to spend much more than 1700.00 if poss. Last engine build was much cheaper than that actually.

Dan you can build a turbo setup for WAAAAAY less than $2000! You may have to piece it together, but, it can be done for a lot less. This is a good read: www.smbaker.com/rail/monsterturbovw.htmlI just happen to have an extra turbo laying here...

Ah but what is it a turbo to... Does it have the correct setup for a pull through carb. Very good artical though. If things dont work out on this engine Im trying to snag I may try building it. Im kinda concerned about the manifold setup and such.. Plus Id have to do it different being an enclosed engine and all. I wonder if I could put all the exhaust and turbo in the right rear wheel well then just pipe the cool boost into the engine compartment (Im not above cutting holes into my allready holey car ) Dan

Looks nice! That would be the way to go, if you can get it for the right price. It's already built, that takes a lot of the trouble out of it. What displacement? Looks like an M11 turbo, I have one just like it. You could have the exhaust ceramic coated, that would help with engine compartment temps, a little. You could also run stand-offs. What have you done on the other end of the fun meter, stopping, have you upgraded your brakes, or plan to soon after installing a mill of that HP potential.

We shall see where it all leads brakes and such. I really am happy with the handling. And the brakes have allways seemed fine from 90mph down stock. If I feel it needs more we will deal with it. If I get the motor Ill be poor for a while.
but the official wish list in order is
1. MORE POWER 2. Fix annoying fried front torsion bushings 3. Freeway flyer trans 4. redue headliner with speaker carpet!! New headliner I installed SUX and is almost worse than it was before.

Yea those kits are like 2000 and up Dustin. If the auction falls through I need to look at options. It looks like I'll need a turbo with the pull through set up, a bought carb manifold (I'm not modding that!) braided oil lines a 2 barrel carb and lots of plumbing! I'm thinking the local muffler man can probably make the plumbing. Then it's just a matter of heat control. I read that this turbo thing is he'll on the exhaust valve guides. I may still just go big and make a 1776 w a stroked crank and dual 44's as I'd still get the 150hp I want and it would last longer. What are your thoughts? I'll know about the motor by 6pm tonight, most likely some bonehead with to much money and no wrenching skills will get it and maybe that's for the best, BUT if I can snag it within budget it's Gunnar be mine!
What kinda turbo you got vw1s? Is it set up for draw through?

The turbo I have is an Air Research M10, from a small Mopar, probably a 2.2 or 2.5. I would guess that it is setup for blow through. I am happy with my NA 2054 so far, 74 X 94. Plenty of power, maybe 140-150HP, but, a little high strung for daily driver use. I am currently running a 125 cam and a 6 pound aluminum flywheel, but, a little less cam, maybe a 120 or 110, and a heavier flywheel would smooth it out a lot. I would also drop the compression a bit, I'm at 10.5:1, but I would think 8-8.5:1 would still be plenty fun.

See thats the thing, to get 150 + NA its generally not much of a street motor, but turbo is only on when you nail it. sounds like the turbo you got would need to be rebuilt with that special seal to use with a carb pia from what I read.

If you are not in a hurry just keep an eye out at swap meets. A friend of mine picked up a nice set up at the Lansing center a few years back for $500.00. He laid down 220hp at the rear wheels early this summer with it and then went 11.35 in the quarter with it and it is still street able.

I saw a TWIN turbo setup at the Bug Out many years ago, maybe '95 ish, guy let it go for $75! He said it was a prototype and he had built his final model and didn't need the proto any longer, somebody bought it, not me. Like Clinton said, the deals are out there, you just gotta find them! If you are interested, I'd let the M10 go cheap!
