Its hard to say- as far as I know, either way you're talking a completely custom setup- so it depends how much the shop charges for fabrication. I'd imagine a TC kit would be cheaper- with the SC- especially remote mounted- you need a mount, some kind of outlet collector to change the outlet to round tubing, custom piping from the outlet adapter to the TB, custom piping from the inlet to your TB, a special length drive shaft/snout, modification to the pulley system.

With a TC kit- if the 60* engines are anything like the 3800s, you can just block off the stock downpipe connection on the rear manifold (forces the rear exhaust gases to come back up the crossover pipe)- then replace the crossover pipe with a turbo mount- and connect the turbo outlet to the stock exhaust with a new downpipe. So all you need there is a blockoff plate, a custom crossover pipe, a new downpipe, and intake plumbing.

I looked on MMS, and couldn't find a 3400 turbo kit, other than the one for the Nbody. I will say though, I've seen some negative threads about doing business with him over the last year or so- so I'd definitely read through those first before I decided to drop $5000 with him. Not saying he's good or bad- I only ordered 1 part from him, and that was something he just got from Ed Morad's and shipped to me.

Yes, there is a BOLT ON turbo kit for turbo charging the LS4 monte's that makes more power than any boosted 3400 I've seen out of the box:

So this kit out of the box will make ~500 whp (that's 3.5X what your current engine makes)- without touching the bottom end, without porting anything- just a turbo kit that has an electric cutout and meth injection. You don't have to worry about some custom kit not fitting right, or having trouble finding parts- this kit has been out for awhile and is proven to work.

Granted the cost is steep- $5500, but the results would blow any M62'd 3400 out of the water with half the work (plus you'll likely need a built trans either way).

If it was me- I'd keep the 3400 for a gas sipping daily driver, and turbo the new SS- then if you get bored later, you can always do more mods (ie turbo cam, new intake manifold, etc) for even more power.

 

nice, thanks man, i think im gonna wait til i get the new one then, youve been a ton of help.

 

looks kinda difficult to install haha, only thing i would worry about is having it installed partially and getting stuck on something

 

umm, but you're talking about building a custom fabricated kit to bolt an M62 onto a 3400. I really think a bolt on turbo kit would be FAR easier to install.

Honestly, no forced induction kit for any car is going to be a 20 minute install- even putting a supercharger on a 3800 (an engine that came with it from the factory and uses all factory parts) can easily take a beginner a full day to install.

 

how hard is the m90 s/c to put on a 3.4 dohc?what all do i need

 

alot of stuff and if its dohc, even more i would assume

 

it proly would be better to just turbo it?

 

Yes for sure. There was a guy on mymonte who did it; but it was super tall (ie sticking out of the hood) and the adapter plates made it pretty ugly IMO.

 

now the smaller one looks good in my opinion, but you dont get nearly as much horsepower and the turbo is around the same price

 

the only problem with that statement (not to say your wrong) is that from what i have seen from when trying to find a M90 supercharger kit is that there isn't one! the only one that I could find was on a 3400 swapped beretta but the guy had made the intake completly from scratch. My advice is to use a centrifical supercharger like the ones from RSM Racing (even though they're on the expensive side) instead of a postive displacement supercharger like the eaton M90. you could still give the M90 a shot but my findings suggest that it will take alittle more fabrication than you might have hoped for.
