Toyota Tech Heads...

[DJ984]

Hey all,

I haven't found anyone who's even mentioned it before but I'm curios... can you put the 1UZ into a toyota MR2?

The only barriers I could think of are:

1) will it fit in the bay?

2) can it be mated to the std gear-box / what gear-box would you be able to use?

quick, simple question but i'd be interested in some detailed answers... there's got to be a reason no-one's done it i suppose but i'd like to know why.

Cheers,

Dave.

how much cash do u have? only a mr2 gear box will work because mr2 is toyotas only mid mount engine car. u can get massive powerfigures out of 3sgtes any way. there was a 600 ps one in HPI a while ago

[WTF-33R]

I have read of a camry V6 motor put in an SW20 MR2 in the states. Tight fit but doable.

The 1UZ though would be impossible, add to it that you will never find a transaxle to suit

can be but not plausible/massive money plus re-engineering of the entire car

narrow V mazda v6 maybe a chance, otherwise I think you would need to pretty much re fab the chassis

Why would you put a V6 camry motor in a MR2 stupid yanks

remember the Camry ads from the late 90's when the Camry accellerated faster than the AU XR6 Falcons? imagine what it could do in a 1000kg car! Here's a link to a wbsite dedicated to the conversion

i think theres a v8 in an mr2 in the US too.

Not that much ha ha!

no, the reasoning behind the thought was simply to have a naturally aspirated engine that had the brute force without all the modifications... you could run the 1UZ in a car that light in std trim and have very satisfying results.

Ultimately, around 3~400HP at the flywheel would be the goal but i don't want to have to spend 10's of thousands of dollars to get such a low output (not that that's a low figure for that engine but i can't justify in my mind, the cost of that kind of figure).

opinions?

yoshimitsu9: was thinking you could mate up a porsche box or something but again... costs start to get a lil stupid.

So, basically, what people are saying is that the limitation is the space in the engine bay?

[urtwhistle]

hey all, i remember some 1 was building 1 of these conversions, check out Lextreme.com

you want 400 flywheel horspower, and you think it will be cheaper to do an engine swap and then tune it for power?

movey vs performance, the 3S will probly be better than the V8, with the added bonus of not performing an engine swap/chopping the chassis/retarded weight balance of a V8 over the rear wheels.

edit - i dont get it, did you want to specifically keep the car N/A?

Why do the yanks go for a V6 conversion? Well it's a heaps better option than the standard 5FSE Camry engine they got in their MR2's.

[scandyflick]

i could be wrong,

but arent the 5SFE's considred an upgrade when you start modding an MR2?

[Silver-Arrowz]

5FSE = 101kw engine

More displacement (2.2) but less power than a 3SGE and not a Toyota G-series engine. The G series engine love to rev out. The 5SFE is an ordinary cardigan wearing guy engine.

[bubba]

F & G refer to the heads, F is economy and G is performance.

sorry, poor explanation on my behalf.

if i where to keep the 3s-gte, i'd like around 400 hp at the fly but i thought, with the v8... standard power would be more than enough in a car that light (working on a power to weight plus the fact that the displacement etc in the 1uz would make a pretty meaty ride in an mr2)

also, if i went the v8, i could stick with an N/A option which (IMO) would be better maintenance and general expense wise. where as, staying with the std engine... i'd be upping boost, frequent oil changes, risk of blown turbo's, etc etc... you know what i mean?

basically, i think it'd be nicer to have roughly the same power out of a standard N/A engine than out of a modified / std turbo one.

that make sense?

there's also the problem of keeping an mr2 engine intake temps cool because of the set-up they have (intercooler replacements etc are limited) so, upping the hp on a turbo engine (assuming that's a result of more boost etc) brings concerns of "can i keep it cool enough not to go bang?" lol!

[DJ984]

so... ok, here's another question to throw out there.

what's the quickers / cheapest / easiest way to get good power out of the mr2 (let's say a goal of 300 hp at the fly) whilst not raising concerns to things like intake temps etc.

whether that be drop in the v6 or tweak a few things in the std engine...

what's your opinions?

I don't want to fk around with modifying chassis and getting stupid amounts of engineering etc etc.

anyone know where to get a 3s-gte crate engine? like the tomei nissan engines you can buy?

and opinions on whether a better option would be an sr20det... keeping in mind the cooling issue

easiest way to get the power your wanting is by tuning the 3S-GTE, and it will be the cheapest by far. supposedly the stock bottom end is one of the weak links to over come, but shouldnt be a problem with 300hp at the fly.

as for cooling, there are a few options. the one i would be looking at personally, is a liquid to air exchanger. if you've seen the video of the GTTT, you'll know they can work well, try to emulate that system, although price will be a bit of an issue here, overall it will still be far cheaper IMO. even still, there should be other water-air set up's for MR2's.

my advice now is to look to jap tuning. i've seen a few MR2's in the tens, on street tires, look there for advice.
