Lightest RW only nissan for sr20vet conversion?

Recommended Posts

Ive been studying the lower poor man coupe models from Nissan

I can get a v35 350gt, R33 gts25, 350z and some others for cheap

here in Japan but does anyone know which would be the lightest

coupe that I could put an sr20vet into?

So far looking at a r33 gts25 as they weigh the same as some of

the older rwd r32, 180sx, silvias and yet seem lighter than the v35 and 350z etc.

A real shame the 350z are so heavy as I like how compact they look.

 

I would like RWD only, no fwd or awd, I have some plans for making

it a daily and would also love to invest in a wide body kit eventually

and fit some large deep dish wheels etc.

Wait, so, you have a SR20VET somehow but not sure what to put it into?

Your fabrication skills are unknown, but you have a SR20VET so.

If you don't got the skills, my answer is a S13 or something it'll bolt into.

If you do have the skills, my answer is MX5.

Skill are not the issue knowledge of the specimens mentioned are but going

for an mx5 would only deserve a late Mazda all alloy 2.3 diesel turbo.

Lightest Nissan coupe is the aim. Otherwise a 310 sunny coupe would

be the choice but getting rare these days and dont offer gts, v35, Sxx or Z handling

or solid feel and would flex like a tissue box if not reinforced/strengthened

S15 is listed as slightly heavier and shorter wheelbase than S14

Are there any advantages over the R33 as the RB25DE is 230kg

and the sr20vet is 156kg.

Im looking now at substracting the weight of the Rb25DE and

S15 and R33 are the same if they had an Sr20de.

I'm struggling to understand that.

I think he's saying that the S15 s slightly heavier than the S14, so why would he choose an S15 over an S14? My answer would be because the S15 is a much better car.

He's then asking if there are any advantages of the S15 over the R33....because something something to do with the weight difference between an RB25DE and an SR20VE. And then claiming that S15 and R33 weigh the same if they have the same engine in them. Which is not quite true, because with turbos etc, an R33 GTST is at least 100kg heavier than an S15.

Sorry not good at typing on new computer that changes always back to japanese.

Thanks GTSBoy you have got it right, however the example I have in mind is a gts25

which the Jp booklet says its 1280kg  with the rb25de trim whilst the gtst is 1320kg.

I havent come across an s15 manual but I agree its an S15 is a great base as it is.

 

In some forums I have skimped across they argue the s14 as being better than the s15

I suppose they are close enough and price would make the only difference.

 

On another the R33 has wide front track that the S chassis with similar suspension

components that dont really give any any advantage over one another.

Maybe there is no real weight advantage in S vs R series models mentioned

but the Z and V35 are just too heavy for any stock SR.

 

As for datsun 1000s, had my fair share of them in all their body types even fitted

a 13b bp in a 2 door sedan that I couldnt roadworthy but was fun before I got 

done twice for noise and non engineer approved engine swap.

I would own one again in a blink but pushing them beyond their design you need

to clad them with very wide tyres  to get more track width and not easy at all.

Sure they have AC cobra wheelbase but no room to put AC cobra like rubber

under them especially in the front.

 

Maybe I should not just limit myself to the SRVET engine albeit still affordable here

some folk are gettign amazing torque numbers from boosted qr25de+t setups?

The post 2008 qr25de is supposedly the upgraded version that got rid of all

the earlier problems pre 08 models suffered. It has more support than it used to

sure no where near an SR but something different.

Well had some people tell me the sr20vet only weighs 5kg less than an NA vq35de

and the vq is cheaper stock for stock. vq40 is also cheap but not interested in the

heavy cars they come in. Almost bought a rwd R32 GTS which seem very light

Wouldn't compatibility and ease of installation/access to aftermarket parts be a priority over weight saving of 100kgs for a "possible" daily driver?

Why can't you start where everyone else starts and consider first the power goal and main purpose of the car?
Once you know power and purpose you can look at what gearboxes/diffs support the power. If the car is going to be drifted or tracked, you can see what chassis has support for the kind of parts you're going to need.
Then you can look at what adapter plate options there are for RWD SR20 block and how chosen gearbox fits into chosen chassis etc....

Otherwise have fun getting your dream setup going in a S12 Gazelle and waiting for drivetrain or suspension to give way under the new setup.

I chose the engine because I can get one for a good deal and has plenty of aftermarket support

Id be happy with usable 260-300lbs of torque more than a high power goal.

Ive got buddies now saying forget the vet and go the vq37 which are cheap and easy to take up

to 260-280lbs of tq and 320hp.

Problem is 350z are cheap but heavy and Ive always preferred nimble rwd cars than porkers.

Looks like Im going to have to just wait for a Nissan Saurus jnr and hopefully can get that rego :)

I believe the R32 Skyline GXi (came with a CA18) was about 1180kg, but then you have to consider weight added by upgrading brakes etc.

Matt I have several japanese sites confirming 1120kg there could have been different trim levels

and the auto adds another 20 or more kg. Definitely a good rig as a base.

That could be right, it's several years since I looked so it's more likely my memory that's added 60kg.

Got a connection for an S12 but its so rusty its too much work.

There is a better S10, looks daggy but lightest big engined bay nissan I can find so far
Doesnt look bad with flares or wide body kit but we shall see.

Also looking at a vq40 bottom end with non variable heads from a vq30de
to make tuning easier  and although I wont get the max hp, 4.0L with some
mild jim wolf cams should be healthy if I can get it fed by some modded
Ducati or Aprilia ITBs (oval square units 65 x 52mm)

another sidetrack looking at s1 Nissan X-trail 1380kg with 4wd qr20de engine

convert to rwd ditch box with front diff add Z33 box -50kg

swap qr20 for vq35 with light flywheel, headers and itbs +10kg 

Rear tailgate replaced with piece of lexan -45kg

Darn it still a 1300kg porker! :(

Good looking box though
