:) I have a few canidates

As for the 240 being lighter, they are an econo box here, so dont even consider them ni the same class. The supra and what not get a lot of their weight from the chassis and parts built for bigger hp.

I'd think the 'econobox' would be the car equipped with tbi and 2 valve per cylinder :) Not exactly weapons of choice to tackle a supra, z32, etc..
Its nice to dream, but the starquest is not in that class.. get real.
In fact, none of the cars you mention can make such a striking contrast to a starquest, as the s13 eh. Call it whatever, but be thankful nissan didn't hang a t3 from the s13.
Furthermore, the s13 has enough -bolt in- nissan powerplants and chasis/drivetrain parts, and a huge enough aftermarket, to enable you to outperform the best of 'em... and do it on an "econobox" budget.

Wrong the G54B is about 20-25kg heavier than the 4G63 SOHC we have. I am not sure about the 4G63 DOHC. The only difference is the head. I can weight one I guess and compare it to the weight of a SOHC head.

The weight fromt he 2.6 comes from the widebdy cars not the engine. I think an sr20 would be a pretty stupid swap consideirng you guys always have a 4g63, and comparing apples to oranges, I think 6 bolt 4g63 dohc>sr20

Wrong extra approx 25kg over the front axle is because of the engine alone compared to our cars.

The G54B is NOT a light 4 cyl engine.

We have done much research on this including weighting cars and engines. There is an extensive post about this if you do a search.

Complete SOHC head weighs 8.5~9kgs. DOHC is??

Total weight for a JDM widebody is 1340kg (2948 lb). Front wheel weight is 750kg (1650 lb); Rear wheel weight is 590kg (1298 lb). Narrow bodies (JA) weigh 1265kg, not sure on wheel weights??

if i want to use 6A12, what gearbox would fit the engine? (as RWD)

Nothing.

Anything can be done though. Would involve a custom bellhousing, and a Supra or Starion or similar sized gearbox.

Regardless of what engine you use you're going to find that...

You can't go past the outright angry roar of a 4g63.

Above 4krpm, these cars scream "GIVE IT TO ME" and so... you do :D

The two other engines I've experienced to have the same SORT OF primal roar is a 1jz and the VH45 nissan v8 (rare engines). I suppose for me I love the SOUND of the engine, I'll stay above 4000 rpm all day just to listen to that noise.

Can't go past a 4g63 on full noise!!!!! MmmMmm VR4....

5 speed.

Would you use a w57 gearbox?

SpidersWeb · Post by **SpidersWeb** » Sat Sep 03, 2005 8:09 pm

I can't remember. Its one of those W boxes. W58 comes to mind.

There should be heaps of info on this forum about it. Just have a look through using the Search. Its the 'what to do' when you keep breaking Starion boxes.

40lbs or more from the us cars comes from the leather seats/interior. They weigh quite a bit more than the cloth seats, also electric seat belts depending on years.

The lightest g54b widebody would be the 86 with cloth seats, and I would go as far to say as it is maybe 3030lbs?

The only heavy part of the engine is the beefy crank, which is 42lbs if I remember right. Thats where most of your weight difference between the 2 engines will come from. Block for block, maybe 10 lbs or less? If it was good enough for ralliart and hks to make a group a/b wrally car with, it cant be that heavy ;)
