1st gen twins....

[JQmile]

I was looking at all the room in my engine bay (esp if I removed the A/C) and was starting to think about adding an S400 as a second turbo I know there are a few guys who have built twins, are they easier on a first gen cause of the extra room? Or still a pain.....

It is aeasier to fit the turbos but harder to fit the exhaust because of the shape of the cab and floor.

My advise would be take a look at all the 1st gen twin pics online. KTA, needmopower, Stomp, swank, CaptainChrysler, BC, CK, and myself are the ones I can think of that have pics someone online of twin setups. See how they did it, think about how you would do it different or similarly, using ideas from them to get yourself started.

Of course Stomp and BC both have run of the mill PDR setups, no offense meant to them btw. That setup is just a 90* drop out the back of the secondary charger, basically the same way 2nd and 3rd gen twin setups are built. It will place the primary close to the block, possibly causing interference with the stock oil filter location. It will place the primary's drain lower than the stock oil drain in the block not allowing you to T the oil drains and will require a second oil drain in the oil pan. Plus the use of a 5" downpipe might be impossible without cutting into the firewall.

Now by placing the primary out away from the block will allow you to retain the factory oil filter location, the use of a 5" rubber boot and intake and possibly be able to T the two chargers oil drains.

Two things, i twisted my bottom turbo to fit a 5 inch DP, with out cutting the fire wall. And second if you can get the turbos high enough (by flipping the exhaust manifold), you can drain bottom turbo into the stock inlet, but run 1 inch return lines if T'ing.

I like the idea of relocating the windshield washer reservoir and mounting the big turbo over there on the fender. I've seen a couple 1st gens like that and it seems like the pragmatic way to go...

I don't know where they put the flex on those set-ups.
