RE: turbo v6
buick grand national history lesson
top speed: 124 mph
0-60: 5.5 sec
displacement: 231 ci (3.8 liters)
tranny: 4-speed AUTO
max power: 276 hp at carnk at 4400 rpm
max torque 360 at crank at 3000 rpm
weight: 3545 lbs
fuel economy: 23 mpg highway
The engine was developed by ASC/McLaren. It started out in '78 as a Regal. 4 years later as the Grand National, 215 were made, it made 200 hp. finally in 1986 it was called the GNX and only 547 were made. please don't tell me i don't know about something when evidently i do. there is y'alls history lesson. it should have worn an ASC/McLaren badge not a Buick one.

apperently you dont know what a grand national is....

Why a motor swap. the 3.8 ford was basically copied off of buick with better upgrades than the stage 1 buick.
1. the ford is an on center block and doesn`t have the "weak" offset con rods the stage 1 buick has to deal with
2. the ford has a far superior oiling system
3. the ford heads are leaps and bounds better than the buick as far as rocker design and flow
4. the ford engine is about 90lbs lighter than the buick which = better times
5. don`t have to worry about swapping GM electronics into the Ford car
basically copy a buick build
morana main girdle
8.5:1 forged pistons/eagle 351 rods
cam with at least 220 dur and 530 lift but speced for a turbo
head stud kit and o-ring head gaskets
fully ported heads with bigger valves
fully ported intakes
55lb injectors
Pro-m Univer
SCT chip burned by VMP
Nitride treat the crank for added strength
weld buttresses in the lifter valley to prevent block splitting (like the buick's were known to do)
2 turbo`s dialed for about 25lbs boost
8.8 rear with girdle and 31 spline axles
procharger 3 core intercooler or equivalant intercooler
1.73 or 1.8 adj roller rockers
modified fox 70mm 5.0 T-Body
this will easily get 500+rwhp and handle it
you would have to do about the same to the buick to handle the same power

here's a pic of an extra nitride treated non turbo buick crank that i had on hand for the GN i have ran these cranks in it. they are pretty strong

and a pic of a con rod/piston. you can see the offset rod that buick had to use when the changed to an evenfire crank
http://www.mustangmods.com/data/8456/pics.2_047.jpg
that rover you have for sale. did you know that was a buick designed engine? buick sold the rights and tooling for the aluminum 215 V8 to rover which became the 4.0 rover V8. the 215 is also the block that the buick v6 was based on. thats why the buick has the usless block skirt. it carried over from the aluminum V8 that needed the skirt for strength
all production buicks had the stage 1 block turbo`d or not so there is no block strength difference in any buick turbo to non-turbo. the pistons,rods,crank,head gaskets are different between the 2 but not much as far as strength wise
the ford 3.8 was a modified copy of the buick but better than the stage 1 buick all around.
stock internals (except crank) are not the best for more than 350rwhp. the addition of forged rods/pistons morana girdle, main studs and a good nitride treat of the crank will allow 750rwhp+. the ford block needs more support in the lifter valley to prevent splitting. weld 3 butresses or gussets across the lifter valley and the ford block will handle just about anything. it is a stronger block than a production 5.0 block.
the stage 2 buick is another story. it is an animal of a block and is an on-center design(like the ford which ford developed first) and shares little with the stage1 block. the current 3800seriesII engine is a modified stage 2 block
the fact is if built right the 3.8 ford can be turbo'd to deliver 9 sec passes in the 1/4 like the buick is capable of.
GN heads flow like crap ford heads (loosley based off of the 351 cleveland) flow exceptionally well even stock and really flow with a good porting job.
i just i wish i had the money to build a 3.8 ford to similar specs as a turbo buick
the 3.8 ford may be the biggest sleeper engine ever built and it is worth it to build one

the GNX was in 1987 not 1986
i agree with you on everything else
