So I have been given a 91 LWB and was thinking of keeping the V6 just in case I had a major failure with my starion Turbo swap. Now the big question is what could I do to this 3.0 motor if I wanted to put it in? Is this motor pretty much the GT 3000 with 16 Valve heads? what about the 24 Valve heads? has anyone done this swap? I did find a guy that did a twin turbo set up on his and said he had gobbs of low end I guess.
As for the reason I pull a offroad trailer I built and im thinking it's around 1200Lbs unloaded. I have a good running rig now but sure notice it on the hills. I can put this on a stand and build it up from there, I know its not the 3.5 but it was free and runs good. Any imput would be great guys.

I always wanted to build a gen1 3.0 with late model 3.5 sohc 24v heads in place of the 12v sohc heads, with a turbo. I would use a fabbed pside exh mani and use the stock dside down to the y pipe, then turn the dside exh up to the pside fabbed flange for about a 16g turbo. Should see around 300-325hp out of that setup if you intercool it well. Over 2x the 12v 3.0 hp of 150 or so, and over twice the torque, too. You would need to thermowrap the dside exh to keep the heat in to run all that way. It should drive like it had a husky v8 in it.
In terms of a 2.6t vs a 3.0na motor, the 2.6 wins. a 2.4dohcT wins by even more. 3.0 is about 150 hp and 175torque. A 2.6t is 206hp and about 225torque. I've seen dyno runs on a 2.4t at 314hp and 300ftlbs on pump gas.

I like the numbers of the V6 for sure, I think the extra 2 cylinders will help on up hill. I also think the turbo adition to the V6 will bring a nice power band threw out the hole torque curve. Dont get me wrong the 2.6 is an animal it self and has great power, but iv become more power hungry with my additions and like the sound of the V6.
My down side to the 2.6 is the balance shafts ( Which I do not have now) Seems unstable at higher Rpms. Im after a serious torgue monster and I think Eddys combo is what im after...
As always you come threw with the answers!

Cant put 24 Valve heads on a 12 Valve block there are minor differences with water jackets. Best bet to do this is get a wrecked Donor SR with 3.5 or maybe a later model 95-96 LS with the SOHC 24 valve if you want to stick with 3.0 displacement. You'll need to get the brain and wiring harness from donor...

Man so my options..ok heres a different approach has anyone thought of a 4G63 2.0 with a 2.4 crank which makes a 2.3 stroker? Im not sure at this point but can have a 2.0 wide block tomorrow if I want it. I have read that there bullet proof and have lots low end. Then there is the DOHC I want as well...Crap lol! V6 sounds good but then I see this 4 banger just smoke all outputs across the board.

Find a 4g64 wideblock and put the 4g63 heads on it and you have 6 more c.i., better torque, and should be able to make an easy 300hp with the right turbo setup and MSpnp.
Then sell the 4g63 short block and recoup some bucks.
The dohc 4g4 should handle 15psi on pump gas with the nice combustion chambers and 4v heads. I hear the gen1 heads flow better, and it seems you need the 6bolt block for best results. There are some water circulation mods you need to clear the firewall.
See projectzerog.com for all the skinny

OK so im going for it! I found a 91 4G64 block at mt local yard for 150, I have found the 4G63 complete head for 200$
I already have a nice header that I bought a year or so ago.
found a 14B turbo from a guy here in town so im after that as well. The guy with the Gen1 head has a full dsm 4G63 gen1 wire harness that im getting also. Now im trying to find which intake I should run as there is many options for diffrent setup's I have seen. Eddy what is the MSpnp mean? Map sensor or? These engines have alot of aftermarket parts
as well as tunner software...and the fun starts!

You'll run into a lot of commentary on the DSM boards about the 1G head having larger ports and being better for top end. It's physics by popular opinion.
A well-maintained 4G63T is good for 400whp+ on the stock internals with proper tuning. You can mix-n-match a lot of parts.
I'd just leave it stock for the time being if you go that route.
Curious to see how this plays out.
