whats up every one. im a honda guy so im not to familar with toyota's but im open minded so i figured i would read up and broaden my horizons. first off, im all about speed. i like to go fast. i have a geo metro hatch back that im gonna swap an mr2 motor into. a few questions that i have are this. my car is obd2, is the 2. in the 95 mr2 obd1 or 2. also are there any hybrid combos like the 2.2 block on the 2.0 head? any info would be greatly apperciated. thanks for your time.

First things first, a 95 MR2 would be OBD1 still. Secondly, a head goes onto a block, not the other way around. Third, what kind of car do you have. Please dont bastardize such a beautiful feat of engineering that is the 3s by putting it in a metro.

first off a know a head goes on a block.... second do u know where i could find any obd2 to obd1 conversion harness's for toyota? and third off a striped out metro hatchback weights about 1500 pounds.... and its for racing so should i care what it looks likes or what it is?

Should I care if you need to find a conversion harness? Answer that and Ill answer your question smart alec.

Give him a break, he is obviously a new user and probably does not know that the GEO is ummmm... well.... Theory, just buy a different car man!

toyotaspeed90 · 06-26-2006, 11:30 AM

and a stripped out mk1 w/o engine is around 1500lbs too

Maybe this is what you are thinking of building http://www.smartuki.com/home.html

Not sure if this is a joke or not...

I won't hate on the geo idea. I've thought of it before, never for racing, more for the funny factor. If for racing the MKI is a far better idea for the 3s's power/torque. OR do the metro right and mount that bitch behind the driver, reinforce everything and make it MRD or AWD!!!!! YEAHHH!!! That would be awesome, your own little american Renault.

I love this idea! What you're talking about would be putting a GE head on a 5S block. It's been done quite a few times but that might be taking the complication of your project to an extreme. It involves plumbing new cooling channels and similar such adaptive efforts.

How is the engine in the Geo mounted? The 5S is designed to be mounted transverse. Have you thought about what you're going to do for a tranny? If not, you might want to consider grabbing a tranny out of a Celica, already font/front.

I've got an extra 5s wiring harness and two 5s's that I've been pulling parts off of if you find yourself needing any bits.

What kind of racing do you do?

Don't know that I've ever come across a conversion harness. There are quite a few guys that are custom blending v6 OBDII harnesses into their cars so I would imagine that if you were persistant enough and good with wiring diagrams and a voltimeter you could do it yourself.

You started the haterizing man, can't blame him for getting a bit heated with you.

mainly quarter miles and some illegal street raceing. i noramlly mess around with hondas but i got the inspiration for this idea form a id at school who had a tsi motor swaped into a eagle summit. anyways im kinda on a tight budget and i found the geo hatch for around 200 bucks now im loking for the knowledge and parts to make it all work. i thought abou the rotational issues of going mid engine to transverse and i figure i can mount the engine in the front the same way it mounts in the back with the exhause manifold faceing the fire wall. as far as tranny goes im not to familar with toyota's other then the 2jz (who doesnt know about that). so any info would be nice. and if your not willing to offer constructive critism or help plz dont bother posting. thanks.

In a front/front application Toyota has mounted the motor in the same orientation it is in the MR2, with the exhaust mani forward. You might find a more receptive audience for your ideas at a celica forum. I would recommend www.celicatech.com. The 5th gen celica is prolly the platform you would want to model your project after.
