MG roadster.... with a bit of jap in it...

Recommended Posts

Hey guys...

 

My name is Stevo (previously s13_Stevo, but couldnt log into my account <_ and this is my new old car...>

 

Its a 1971 MG Midget, which I picked up here in perth after my van died...

 

 

 

It underwent a full body off restoration 8 years ago, in which the owner replaced the horrible british boat anchor with a slightly nice jap engine of the same vintage...

 

It now sports a datsun 1200 engine with extractors, custom exhaust and slightly better carby setup..

It has about 85,000 miles on the odo, which is about 130,000km or so... and has been looked after very nicely...

It weighs in at a fat as 711kg :woot: which makes it handle like a go kart...

It is of course... rear wheel drive... going through a 4 speed datsun 1200 gearbox to a british LSD on the back...

Disk front brakes and an unfortunate case of drum rears...

Oil cooler and bigger radiator

Fatter than standard rims and tyres

 

Future plans include:

Upgrading to disc brakes all round

Lower front end and raise rear a tiny bit...

Stiffen shocks, big fat front swaybar...

Bigger rims

Nissan engine/gearbox conversion... most likely ca18de or sr20de...

Old school race style front lip...

 

Here she is...

That's awesome. An SR20DE would be a good choice for it :)

yeah im just trying to figure out how much the entire sr20de conversion would cost...

im thinking of using an sr20 diff too so that i can get rear disks, and the upgrade the fronts...

5 speed would be much nicer on the freeway...

 

an sr20de at 110kw in a 711kg car gives a nice power to weight ratio of 155kw/tonne... :woot: (I think a standard sr20det sil is about 125kw/tonne)

 

I think a buget of 2-3k would be good to sort out engine/brakes/suspension... if I did a fair bit of work myself...

 

Any other comments?

ahah yeah that was me... :P

the buildup and such is here: The Magic Surf Bus

 

Was previously s13_Stevo but no one seems to want to help me out to get my login/account back... <_>

 

That van was the best project you could ever do for under 3k total INCLUDING buying the car :lol:

Nice mg mate, looks very neat. My old man has an MGBL or some shit, looks like ass compared to that.

Congradulations.

What did you pay?

The rear diff setup from a sil would be near on impossible, alot of fabrication

 

Is the rear IRS or solid? just rebuild the standard LSD eventually to get it fresh and predictable

 

In a car that size and weight, rear discs aren't really required, most braking force would be at the front anyway, so just upgrade all your lines to braided, and get some bigger front rotors with caliper adapters or larger setup, but the best upgrade would be the lines and pad material, 30 year old rubber lines cant be that healthy

 

 

The engine setup would be perfect, an S14 SR20DE not S13, as it has more power, better delivery, VCT, and can be had for very little more than an S13 version, backed by a 6 speed S15 box, to get the most out of the N/A motor, would be awsome then and you wouldn't have to worry about the strength issues of the 6 speed as it's only N/A

 

The heater box assembly might be required to be removed/modified, get rid of it completely, no one would be any wiser, and as for chassis width to fit the engine, looks to be tight, and engine bay lentgh also tight, but have fun

Thanks...

 

Yeah he probably has an MGB, they are a bit rounder/softer looking... still nice cars though..

 

and thanks I_like_drift yeah i think the whole diff thing would be a huge effort, but I have seen it done before on an MG midget...

It is on half eliptic springs and crap shocks on the back... I think...

 

I know I probably dont need discs on the rear, but I really hate drums... ahaha its just a thing I have against them..

But definately need to upgrade the fronts sooner or later, they really arent up to the job, even for normal driving...

 

Yeah the heater box and shelf across would need to be removed, but thats ok... it does nothing anyway...

(British engineering: to turn the heater on, you need to open the bonnet, turn on a tap in the coolant lines, then hop back in the car :blink: )

I have seen Chevy V6 conversions and MGF 1.8 litre conversions done fairly easily... so I think it would fit without too much hassle...

 

There is certainly a lot of potential for turning this car into a street/motorkhana weapon B)

hey mate,

 

looks like a neat little MG, we have a red mgb-gt sitting in the shed at home that we just got the motor back for, cossie pistons, etc... should go alright when it is back togethor.. plan is to basically deck it out as a racer, has a cage, etc.. they are great fun to drive MG's...

 

have you had a look at whether a mgb rear end might fit in, then you might be able to use the disk breaks from that..? they also make irs kits for mgb's which apparently make them handle much better..

ahh yes MGB-GT's are awesome :yes:

 

They have a little V8 in them dont they??

I was cruising next to one down the freeway the other day...

 

MG owners seem very friendly... always get a wave... everyone is 30 years older than me though...

its pretty much my mid-mid life crisis....

Just need to save some cash and start building it up... a roll bar would make me feel a lot safer...

I agree they are awesome to drive though...

 

and the reputation of having that magic surf bus will stick with me forever..

even at parties and such random people know of me cos of the van :lol:

i say do a full suspension and chassis strengthening/bracing and brake overhaul first before the engine conversion,

 

just get an L20B from a 200b datsun with a turbo kit on it, should just about bolt straight in with the right engine mounts :)

they are a pretty well braced little unit from factory with big box sections for the wheel arches and lots in the floor...

but being a roadster it could always use some more...

Suspension needs some work... rear shocks are dead and the wheels scrub on inside of the guards through hard corners with 2 people in car...

The brakes are a must though... gets a bit hairy braking hard :woot:

 

yeah an L20 or something of the sort from datsun would be excellent, keep it old school and easy to fit in... good idea...

Even if it is down on power slightly... its not like you need much to make a 700kg car move :rolleyes:

 

Thanks for the ideas...

definately take that into consideration

why not a sr20det or a ca18det ???

 

that kind of power in a lil midget would make it an absolute animal... however i think it would cost a fair bit of $$$

 

good luck mate, love the car :)

i mentioned another old datsun engine as they are easy to come by cheap, and very little work would be required to get it running in comparison to an SR20DET for example, no doubt an SR would be insane, but $$$$ is always a big factor when it comes to modifying

 

and a fresh L20B with a nice webber, still isn't lacking for power, sure it's not great but at 750kg in the end with double the torque it has now and with a 5 speed in it, you'd have more than enough fun right there under your right foot

 

a good LSD and brakes on top and your laughing, you'd own the hills

 

anything you can strip from the car to make it even lighter?

sound deadening, heater box and piping, carpet, spare wheel and jack, cat, roof lining, door glass and regulator, lighter rims

How much is it pushing out now?

 

its pushing out about 50-60kw at the engine... :lol:

it needs a tune though at the moment...

 

the other day looked under the car and found my rear right shock hanging down, I snapped a mounting bolt for it when I took her rally driving... :ph34r:

Took about an hour to get it back in, and realised there is definately a LOT of scrubbing of the wheels by guards and suspension up the rear...

 

After doing some research Ive decided that I need to...

 

L20b or similar engine with 5 speed box...

flare the guards out front and rear... and purchase some 14 or 15 inch rims with correct offset.

Definately need a new spring and shock combo... but will have to wait til after the new engine, because I need to get it correct for the added weight.

Big front swaybar...

Old school style front lip/air dam and rear diffuser...

Polished individual roll bars for driver and passenger behind seats...

Respray...

also i found out a good braking mod is to put the front discs on the rear hubs... (direct bolt on) and purchase a larger brake setup up front from some donor car...

Whats the L20B like to drive? it seems like the logical step up from what I have in my car.

5 speed gearbox or 4?

L20 will f@ck the weight balance in that thing. I would think more along the lines of a toyota 4A-G with carbs (if you must stick to shit technology, efi if you'd like grunt and nice economy and driveability).

 

A mate had one with a trick 1300GT escort motor, weber sidedraughts, rollcage,trick suspension etc, it was a pisser to drive. But would have been 100x better with a modern motor that idled nicely, was liveable noise wise, started every time etc.

nah I have no problems going something new, in fact I would rather have an sr20 etc than some old carby fed anchor...

Its just that from a ease of swap perspective, the L20 would probably be cheap and easy...

 

at the moment though im missing my old van... and I need to buy a fair bit more windsurfing kit...

Ive been getting some decent offers on this car from random old british enthusiasts which are very tempting (ie few k more than I bought it for) so I think I might fix all the little problems, sell her, and start another van project.

It's got twin 45mm webers on it which desperately need a tune, full exhaust/extractors backed by an R30 stumpy 5 speed, goes pretty hard, but once she's got a tune along with an electric dizzy and a cam, she'll be sweet

Did a comp test an got 185psi across all 4, looks like it's had a rebuild previously too as it's got an L16 head (W53) on it, higher comp, but less flow unless it's been ported which i dont know

 

I suggested an L20B for your car as it's an easy conversion from what you currently had, as for weigh bias etc i hadn't factored that in, it will be heavier, but not a large amount 30-50kgs at a guess, L18's are lighter than L20 as they're 20mm shorter in block height, so even less of an increase in weight for less torque
