I'm goin to have a spare motor lying around soon that i can play around with. I was wondering if anyone has ever tried/had any luck trying to twin turbo the 1.8 motor. I know ill have to mess with the ECU, injectors, fuel pump, manifolds and so on and so forth. Any tips beyond that?
TT on a 4cyl is not very effective unless you have a VERY boost happy motor that can turn high RPM's to all hell. Where you can justify an offset setup, one small frame quick spool and a large frame high flow for the top end. I'm not sure but I don't think GM has ever made a motor that fits that criteria, @!#$, even across the big 3. They all like stroke too much. Again, could be wrong since I have very little experience with some older motors, but even the duke....wouldn't do it.

I'm guessing he's working on a first gen with a 1.8L engine... or he doesn't know what's under the hood.

IRON DUKE!
GMR has got nothing on this
^yes sir...thats what I meant by the DUKE. While it does have a nice short stroke, to get even decent power levels that could utilize a twin offset setup it would require you to run a completely aftermarket block which takes SBC 350 heads and so forth...it's no longer a duke IMO. The stock Duke from what I've seen with standard pistons, rods, ect keeping close to the original block and so forth the upper limit I've seen is about 400hp....not enough to matter, you can still get a BB medium frame single turbo setup that can easily do that.

Lord knows I've had notions of de-stroking a LN2 by using a '82 OHV 1.8L crank... and maybe even turboing it. But I've never thought of TT-ing a 4-cyl. It's just simply unnecessary! I mean, unless you're gonna go compound... like you see on a diesel or the last gen RX-7... there's no point in doing it. And if you go compound... hope you have, like, no static compression to speak of. And maybe discount access to lots of high-octane fuel.
Go beyond the "bolt-on".

about 80% of the people who fiddle with the FD will swap from sequential to single turbo anyway.

IRON DUKE!
SUPER DUTY FTW!!
Screw the twin turbos this guy in another thread is doing a SR20 swap!

How 'bout Iron-Duke w/marine stroker kit (3L!) Super-Duty & turbos... And Smokey Yunick's Hot-vapor Induction system? WIN! WIN! WIN!
Besides... I doubt that guy in the other thread will do what he's talkin' 'bout. Ideas like that, you either talk about them & do them or ask about them & don't. I say he's another that leans towards the latter.

this is fully retarded. you never put 2 turbos on a 4 banger to begin with. its inefficient.

k thanks for the input. It was just an idea, and aperently a bad one at that.
