Anyone know the dimensions, weights, bore, stroke and compression of this engines?

I'm just running through a train of thought http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/devil.gif

If anyone has a pic of one with the head removed that would be tres useful too http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

Can't help you on those dimensions but have seen one fitted in a MK2 MR2 before.

Nice conversion.

[Nathan]

Insane. Where the hell did they put it? Did they fit it in the cabin and worry about where to sit afterwards? http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/wow.gif

[alex h]

I've seen one in an IS200...so it should fit a Supra....oo-er have I just given the game away??? http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/wink.gif

[Martin F]

I'm pretty sure it was the 3UZ or maybe the 1UZ, i'll try and dig the article out sometime.

It wasn't the fitting of the engine which was problematic, more the turbo charger AND supercharger. It was in Turbo magazine (US mag) last year.

Yep, TTE themselves did one for a laugh. Nice to know that at least one of the big Jap manufacturers still has a 'sense of humour dept.'

[alex h]

Does any one have any pics of the unit? Out of vehicle? In vehicle? Heads off? special versions?

1UZ pics would proabably do as well...

[Nathan]

lol, theres a few pics in my gallery here...

Not very good pics mind.

[alex h]

Cheers Nathan - HKS have a drag Supra with a V8 in it...I take it that is the 3rd engine....in which case are there any specs on the engine available? Do HKS do turbo kits for the general public to buy?

[Syed Shah]

Whats that V12 in the link?

I wonder if a V12 would fit in a Supra? http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/biggrin.gif

Quite useful then.

Alternatively, if you just want utterly bananas torque buy this... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2458489286 (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2458489286)

Ah I see...hmmm well what I'm after - I'm contemplating dropping an NA 4.3 into a NA Supra with a fooked engine. As I see it the weight of the 2JZ should be similar to the weight of the 3UZ (cast iron vs all ally) but importantly it will be further behind the front axle. Then at a later date I could drop the compression, get an ECU, custom manifold and two turbo's....also as I see it, the 3UZ is being used by Toyota for the JGTC...and at 5.2L (is the Tundra's 5.8 the same unit?) there is scope for lots of power to be made in NA only form + the more you bore it out...the less the unit weighs as the boreing process only strips away material (only marginally replaced with a bigger piston).

So i'd like to know the weights of the two engines, the relative strength of the internals on both and how much spare meat there is per cylinder. The stock 4.3 is 90x82mm (ish) which isn't a bad start....would like to know how revvy it is and how accepting it would be of a light flywheel and Getrag conversion....

Shoot my idea down in flames if you will/can http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

[Syed Shah]

Looks ideal Alex, on paper.

Downfalls? When you got off the tried-and-tested route, you need custom bits, and that costs money. WHo does the parts you need? Will HKS supply?

[alex h]

Yes indeedy they are the major headaches....if I can get the engine in and working (prop shafts gearbox etc) the playing about afterwards should be relatively simple. I've found a TT conversion for the 3UZ but it's in a LS430...from the looks of things the Supra has a bigger engine bay. But its an idea I can't really work out till i have some raw data about the engine I'm thinking of

Well that really depends on whether you are serious or not...

My honest opinion? I can't see you getting anything out of doing this that will outweigh the huge amount of cost and aggravation incurred.

Good idea, but only extreme circumstances would warrant it. (IMO)

[alex h]

Huge torque and lower lag for the same HP...would be the ultimate goals with + the added bonus of a better CoG/weight distribution.
I'm not sure if I'm serious yet....it could be part of the plan for 2007. But yes I could just not bother.

+ V8's sound great http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

[Martin F]

Interesting idea and can see why it appeals.

Guess the first thing would be to see if the existing boxes (like the V160) would mate up without too much trouble.

[alex h]

Having an SZ-R with the 6spd already as the donor would be the ideal...do Toyota tend to use the same fitment for most of their engine's/gearboxes?

Lots of questions. Prolly no answers as it is a bit off the wall...maybe I'd be better off with a 3S-GTE http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

Not being rude but getting the engine in and working is enough agg in itself. If you had only been watching over our guys carrying out the 2JZ TT into IS200 conversion I am pretty sure you wouldn't even be contemplating this.... http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

V8's sound lovely, yes, but a straight 6 modified to rev properly ain't that bad either...

I genuinely wish you luck if you decide to go for it, after all, V8's have been fitted into MA70's so I guess this is the next progression, but do not underestimate the work required for engine swops. It's made much harder these days with all the wiring/ECU issues too. Just getting our 2JZ to work with an F-Con Pro whilst still interfacing with the IS200 loom and original ECU (to retain fault code reading, alarm and other parameters) has been a mission in itself.

[alex h]

I've seen/read the thread - not sure what stage you're at now...I know you'd got it in and mounted - and even running...but don't think it was hooked upto the wheels http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

I'm not doubting it would be tough...but it everyone needs a hobby (Petrol won't exist by the time I finish no doubt).

I have read a rumour on the net that there is a 3UZ in a Supra in Tazmania, trying to investigate this rumour. If anyone else finds anything I will be most grateful.

Yes, is driveable now, although there is still wiring work to be done. I think Simon (the guy doing it) only has a few strands of hair left now. He's very proud of what he's done though, as we are him, and it will certainly look good on his CV http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/smile.gif

We were originally planning to graft the whole JZA rear diff/axles/subframe onto the IS but the amount of work required is immense. Can be done, but like anything, money...

Bit of a shame really because it's the strength of the rear end that will ultimately be the issue. For sure, stuffing big-twin power (another sore point- cutting up 6K's worth of turbo kit to make it fit) through the OE diff will be interesting, if only because of the laughable ratio. Should make the acceleration 'interesting' anyway http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/biggrin.gif

[eyefi]

alex, check out these guys, lots of engine swaps

OK, so i lied about the MR2 conversion http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/sad.gif It's a V6 1MZ-FE thats turbo charged and supercharged.

Still an impressive installation.
