Being a DSMer....let me set a few things straight:
G54B.....Heads like to crack, MCA jets, timing chain rattle (abeit usually from a worn out motor with low oil pressure), aftermarket is about a hard to find as a virgin after prom night. The bottom end IS strong....the pistons are not. This was a NA truck motor they stuck a turbo on and tweaked and changed things for 7 years trying to get it to work. By the end, they almost had it....But the 4G63 had already been scheduled to replace it (It actually did in AUS, late 80s quests with 4G63). The wonderful (sarcasm) TBI setup often causes issues with poor connections at the injectors and now with 20+ years on the wiring....getting brittle and falling apart. But......it is doable. If you do the non-jet head, build the motor properly and keep up with the upkeep, it will serve you until you get tired of it.
4G63....The Small Block Chevy of the import world, the design was first used in 1972 and added a DOHC in the 80s. Since then it has been refined and tweaked to become probably the most widely known and feared 4 cyl's in the world. Why?
World's fastest 4-cyl....6.86 at 199mph Brent Rau
World's fastest AWD 4-cyl....7.70 with 195+ mph traps John Shephard
Crankwalking is not as common as u think. It was primarily only the early 2g block (95-96) that suffered from this and even then it's like an estimated 10-15%. And they have found out why so that will not be an issue.
However, most of the time you will be using motors from the early 1g's (89-92.5) known as the 6-bolt motors. These motors are 600hp capable on the stock motor, easy to find and respond very nicely to mods (300hp with stock turbo). And no, you do not have to use only the truck block. Visit Buschur Racing's site as they have built countless 4G63 Starquests that are running 9s and 8s consistantly. And they sell the conversion parts too. Most of the tranny options are PG, TH350 and/or TH400. Im sure you can get an adapter to mate a nice T56 or similar to it. Let's not forget the aftermarket of the 4G63....where do I start?
SRT4.....if you want to fab everything up (since no one has done one yet) then im sure it would be feasible. But, consider that the SRT4 motor isn't exactly sitting around in people's yards (4G63's are EVERYWHERE!), the aftermarket is decent and good luck convincing someone that you kept it a dodge by doing the swap (We all know the Conquest was imported for Dodge by Mitsu).
SBC V8s.....Hate to say it, but by far the easiest and cheapest. Power is ok considering the extra cubes, but you also have tons of extra weight up front. The Starquests were awsome hadling cars at the start considering the near 50/50 they had, but the extra 200+ lbs of V8 and trans will upset that balance. A nicely upgraded 350 can put out 250-300hp on pump with a simple carb so no real extra wiring needed.
The Starquest body is still one of my all-time favs with the gorgeous aggressive lines and wide (Post 86) stance often was evil to see in your rear-view mirror. The interior is ok, but lots of gadgets and small buttons that wear off.
