360 rep 1mz VVti swap

[Paul Woods]

As another 1mz Mk2 swap comes to an end, no build thread, i figure you chaps have seen me do this a bazillion times now, so here is the money shot.... this one came from a JDM Avalon.

I build quite a few cars that never get a build thread, just thought you might want to see something slightly different.

Anyhoo.... on with the show, the customer wanted a diary, so here it is, a nice Mk3 360 rep awaiting a 1mz VVti.... let the games begin.

Engine now removed, all hotwork now completed in the bay, new mount welded in and bumper removed for easier access...

The 1mz VVti v6 engine has been removed from the Rx300, stripped and ready for rebuilding and detailing.

What kind of performance do you get out of a 1MZ MK3 swap?

The kit looks reasonably nice, hard to tell with it in the air! Wonder if it would actually "V8 KLR" a real V8 360?!

[Paul Woods]

No it wouldn't, a real 360 would destroy it, they are 400bhp and have a 0-60 of 4.3 secs.

The Mk3 with a Vvti 1mz will have a 0-60 of around 5.5-6 seconds, although the bodykit is going to add a bit of weight over the stock Mk3 panels, the V6 does take the kit to a different level though, it sounds the part and becomes very convincing to the uninitiated.

[Torero]

Looks the part, Paul. Great work, I really love the Mk3 conversions as they are far more complex.

I have to say I'm impressed with the DNA kits, they have an interior kit as well that makes it very difficult to identify from the real thing.

I would imagine from the power to weight ratio you stated on another thread that the 2GR would get it even closer to the 4.3 second mark.

[snowtigger]

A 2gr mk3 will kill most other cars and will come quite close to a 360, turbo it or supercharge it and you've got a winner.

[kalsingh1]

Just give us a reminder, in your opinion will the real 360 still crush a dna 360 with a 2gr ? It would be good to have some comparison figures on this too.
With these more powerful units going into the roadster with the dna kit, would any suspension upgrades need to be done to balance with the quicker power availiable.:icon_lol:

[Paul Woods]

I would expect it to be close, power to weight wise there would not be much in it.

[snowtigger]

I bet its close on bhp per ton of weight just have a look at Paul's weight V bhp/torque list of cars that the 2gr engine beats, there's some really exotic cars on the list r8 to name one.

[kalsingh1]

Where would I find that list

[snowtigger]

Tiggs will love this shit....

Some interesting comparison data to give you an idea of the performance levels this now offers.
I now have the same power to weight ratio as the following factory spec cars....

all taken from pauls build thread of his mk1 2gr powered car.

[kalsingh1]

These are serious cars. Isn't the roadster heavier than the mk1 though. Especially with the DNA Ferrari body kit ?

[loadswine]

My old Roadster in bodykitted,chargecooled turbo form, weighed in at 1000Kg with half a tank of fuel, so a stock one, slightly less. Don't know about the weight of one of the faux fezzas.
One thing is for sure though, if you have any more power than stock, you need to get as much bracing on the thing as possible. You will have plenty of power, but no driver aids. A proper 4 wheel alignment is necessary too, if you want it to go where you point it.

[kalsingh1]

That's a lot to consider. Will the standard suspension be ok

[snowtigger]

If you want the car to sit right and look the part I would go adjustable height coilovers the ones that you adjust the body of the shock rather than lowering it through the spring platform.

You could also get shorter or springs as well, and a bonus is a better ride.

Do the DNA body kit builders or other people who have built this kit not be able to advise you?

[kalsingh1]

I,ve just looked up the kerb weight on wickipedia.

Merc SL 1,194 kg ( SL55 500bhp@516 lbs/ft)

Toyota Mk3 1,131 kg, (2gr 325bhp@285 lbs/ft=woodsport)

Can someone help me to understand the above. On the face of it looks like the SL55 has more of everything and the weights are not that different ? So how is the Merc SL63 in the list above the same in power as the 2gr? :icon_surprised:
Sorry about the igorance, still learning.

[dgh938peg]

Merc SL is something like 1850kg...

So 500 / 1.85 = 270bhp & 278tq per tonne
and 325 / 1.131 = 287bhp & 251tq per tonne

[kalsingh1]

What does that mean in relationship to real on the road driving ? Is the 2gr in this question then quicker all round, I know top end speed is another matter.

[dgh938peg]

Difficult to say.

In real terms they're probably pretty evenly matched from a straight line drag point of view (imagining the 2 will be quicker off the mark because of MR layout but the Merc will claw it back later on) but when it comes to throwing a car through the twisties ... you don't need me to tell you that chassis setup (grip) and lightness are key :thumbsup

[snowtigger]

also the early mk1 are 900kg to start with and we reckon with the 2gr its about 1100.

You need to get a ride in one - a mk1, 2 or 3.
I suspect the mk1s and 3s are truly scary but the mk2 turns into a highly capable gt car - quieter, faster, easier to drive fast, more relaxing to be in (less noise and gearchanging).

[Paul Woods]

The engine main components now painted...

[kalsingh1]

Nice colour scheme

[Paul Woods]

Thanks, we think it works very well with this particular replica.

Engine and gearbox now under the car ready for fitting...

[Grenade]

Oh yes, it looks wicked and I can't wait to see a "walk around" video of this car. I like it a lot.

[jimi]

according to the stats that i've got

a standard MK1 weighs in at 975kg
a standard MK3 weighs in at 950kg

both weights are straight off the showroom floor with the car fully loaded (full tanks)

That MK1 figure is for an AW10 (which had a different engine and was never available in the UK) not the AW11 which depending on model and spec (1a/b, coupe, moonroof, T-bar, SC, Auto, A/C, cruise etc) weighs in at anywhere between 1020 and 1131 Kgs (kerb weight)

[snowtigger]

I wonder if anybody's imported a aw10 or converted one to v6 or turbo would that be sacrilegious?

[kalsingh1]

So with new kerb weight, how drastic does it change things. I don't think a merc sl55 is near 2 tons. It's very close to a mr2 roadster ?

[Paul Woods]

Actually it is nearer 2 tons.... http://autoadrenalin.co.uk/#/mercedes-sl55-amg/4513271690

[Paul Woods]

With the engine now fitted, i made the axle bearing support bracket, here it is tacked together...

This has got to be one of the best looking replicas out there! That motor looks gorgeous. Would love to see how it turns out. Great job as usual Paul!
