astina bg 1.8 DOHC vs astina V6

[speedyj]

What is faster?

[chicaboo]

I don't think they do a V6 in the BG? Either that or I'm insane... But if you mean the BA, then there's not much between them stock, but then the V6 has massive potential and came in several versions, plus it can be supercharged easily with a kit that's out there at the moment.

[skippy]

I have a BA V6 and a mate has a BA 1.8,

Was pretty much even when we did um compare but he went overseas before I really mastered manual.

He drove mine and said it was a bit quicker,
I drove his and noticed some difference, nothing huge.

One thing is for certain at new retail price you would not of spent the extra 8k (I think) on the V6 soley for more power (12kw).
92 vs 104 as I recall

Where would one find more information about such a kit?

1.8 BG astina
0-60mph: 8.1 s
0-100mph: 26.6 s
Quarter mile: 16.80s
Kilometre: 30.30s
Top speed: 201 km/h
Power to weight: 129.87 bhp/ton

2.0 V6 BA astina
0-60mph: 8.6 s
0-100mph: 28.4 s
Top speed: 203 km/h
Power to weight: 119.83 bhp/ton

these figures are taken from here:
http://www.globalcar.com/datasheet/M...FGLX2.0iV6.htm

they may not be exactly accurate, but in austrailia the BG astina`s all have a cat, and 129bhp at flywheel, where as in the UK the cat version wasn`t introduced until 1992 so the earlier BG`s had 140bhp at flywheel.

Hey Vaughan,

you'd need to ask Pete about it, if I recall correctly he said there is a guy in western Australia that imports them for a tad over $2000usd? I think you have a hardtop yeah? That helps as apparently there is more room under the bonnet. But ontop of all that you need an EMS like Microtech LT12s or a Haltech of some sort... The supercharger he told me about is an Eaton M45, which should be perfect for your 2.0, but I reckon Pete should go for the M62 since he's got the 2.5 now and wants 250-300whp or something insane eventually...

I've never been there but I think you can find out more about the supercharger kit on the MX6 and Ford Probe forums?
Gav.

thank You geetee, that is what I thought.

[chicaboo]

Before you get excited, I'd be impressed to see a 1.8 BG getting to 100 in 8.1s. Even when they were new with the 92kW DOHC engine... Someone with a timeslip can put me in my place ofcouse, provided they describe what mods they had to get it down to almost 8s! The same goes for the BA V6 also, 8.6s sounds pretty quick if you ask me. Considering the SP20s were only a low 9 and the BJII 1.8s around a mid to high 9...

Those figures just sound a bit ambitious to Australian spec cars,
Gav.

my v6 auto dragin on a "closed road" from 80km up is level with a bj1 manual, never tryed a BG

[chicaboo]

The BG 1.8 DOHC BP engines have nothing on the BJ FP 1.8s, even with their 7500rpm redline they just don't have the torque to take on the FP... I've raced (under controlled conditions ofcourse) Mazdabator in his manual SP 1.8 when my auto was stock, from 100 the auto would slowly crawl away and by 140 it would start to jog away quite convincingly. When the auto was modded (minus CAI) it was lineball with a stock manual BJ 1.8 until 140 where the auto would walk away.
One of my mates tells me that my manual looks quicker than the auto did on the highway, even though I don't really feel it myself. But I've not raced anyone in the manual so I wouldn't have a clue.

From 80kph autos have got pretty good gearing and will match manuals quite happily since they have more torque at the wheels. But don't challenge a manual from 60, you'll get slaughtered!

This is something quiet interesting, I have been Driven SP18 MK1, My bros sp20 and my two BJ's and i have been in Mcwillys Astina. They are all very different cars:

SP18 Mk 1 i find comparable after about 100 kays and hour to my mums Mazda 6, it is very comfortable about 80 kays and over. I gave Gavs car a bootful and pulled to a quiet impressive speed in a short period of time. It was a nice car to drive.

My Brothers Sp20- It goes very nicely especially with his recent mods, it feels like a very confident accelerator and you can really feel the torque it has. The gearbox feels alot nicer than mine and you can see that it would be about 2 to 5 tenths of a second quicker over the quarter mile.

My 1st BJ serries II- was a very nice car to drive, with very minimal mods it went very well for what it was and I think it would have kept up with a BG with the BP motor and a SP20 (i tested it numerouse times with local sp20 drivers).

My Current BJ serries II- Is a awsome car to drive it goes very well for what it is and has beaten many simularly powerd cars, before my brother put the exhaust on his sp20 I could just nose in front of him on a dash to 100 (some of you may have seen that on the Australia Day Cruise) now with the exhaust I know his car could beat mine and maybe a BG with the BP to a 100.

I have raced a BG Bp (Mc Willys car) and im not sure what to think (i had 2 people in my car and heavy sub box, but it was very even to the middle of second than he started to pull away but my car has no mods on it where as he has the exhaust), I will say that after going for a ride in it up to Rosemount Vineyards that it does go very nicely but as gav has said I think the BG's do lack the torque of the newer 1.8 motor, my friends are amazed at how well my car pulls in top gear.

I roughly reakon that all the cars would be very simular on the 0-100 kays dash I think the sp20 would come out in front, Closely Followed by the BG BP, and very close behind that would be the manual 1.8 and then Sp18 MK I.

Just my 2 cents.

speedyj> myslim ze neco kujes...but BG is faster;-)

[boostedbatman]

what the heck does that mean

[geetee]

i agree with chicaboo about the figures being ambitious, i think my car is pretty quick but i think i`d be happy if i could get to 60mph (100kmh) in 9 secs.
its been timed on a nokia phone using the speedo and it was 9 secs, but accuracy here would quite obviously be questionable!!!
there`s a meet in the Uk www.rotorstock.com at which there will be at least 5 BG`s and some will no doubt be taking part in the drags.
or should that be taken apart..........
most of us have the usual airfilter and exhaust mods though.

Maybe as I own a V6 I am a little biased but these figures do seem questionable.

[QUOTE=geetee]1.8 BG astina
0-60mph: 8.1 s
0-100mph: 26.6 s
Quarter mile: 16.80s
Kilometre: 30.30s
Top speed: 201 km/h
Power to weight: 129.87 bhp/ton

2.0 V6 BA astina ( in link supplied is 20 kg heavrier than Aus Spec)
0-60mph: 8.6 s
0-100mph: 28.4 s
Top speed: 203 km/h
Power to weight: 119.83 bhp/ton



Here is what I have found, from Redbook
Ba's are all for the Aus spec 96 Manual Hardtop, V6 vs 1.8l
BJ II-J48 Sedan Protege Shades 4dr Man 5sp 1.8i (June onwards)

V6 first then BA 1.8L then BJ 1.8l

104 Kw vs 92 Kw Vs 92
1190kg Vs 1120kg Vs 1123 Kg
87 KwperTon Vs 82 KwperTon Vs 82 KWperTon

NO V6 figure for Torque Vs 160nm Vs 163 nm

http://www.redbook.com.au/vehiclesea...T&key=MAZD96AR

And I have always been told the V6 has considerably more torque, (Assuming this is true) what would make the 1.8l quicker or as figures above show considerably quicker.



And Thanks Chicaboo, but $2000 not quite easy enough for poor ole me, thanks anyway.

[skippy]

28secs is a long time to 160 KmpH.

But 20 secs from 96 to 160 seems like an eternity.

FYI 96 = very top of 2nd in the V6 Manual.
I did this on Sunday on a nice straight, starting in 4th and it didn’t seem that long.

after i get ma new clutch ill see how fast it goes to 100 HEhehehe

[boostedbatman]

And no one has posted the hardtop.......damn
BA Hardtop = 1240 kg
KL-ZE engine 160-170hp? (only mods when car was fit and healthy = HD Clutch and CAI)
Best 1/4 mile ET= 15.8 @ 142 kph [(2.3 60ft) did manage 2.2 with worn rings and coilovers though recently]
so I dont know what 0-100mph equates too but its a heck of a lot faster than 28 seconds

[chicaboo]

the old mini moke would do 0-100KPH in 28s...
