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.

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

Here's a Mk1 MR2 with a supercharged 3.8 V6 GM Motor (similar to our VS-VY motor)

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

Not that much :yes: 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?

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?

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!

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

Edited by DJ984

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.

    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it. 
    • Not yet quite as bad as what we've seen a Jim Berry clutch do in an R32 GTR though when it decided to cut a chassis rail in half... Still very very gnarly and a great reason to avoid.
