Engine rebuild kits

Skitz · 02-26-2006, 09:21 PM

Ok I've been looking at the site, even the FAQ, but I can't seem to find the right information or anything for that matter about engine rebuid kits.

I have an 87 MR2 with a 1.6 DOHC engine, non supercharged. Now I don't the name for the engine, which I believe is 4age - but still not sure.

I've been looking at this site which sells kits, http://www.rpmrons.com/Toykits1.html and was wondering which kit is actually for my engine - like is the engine the same as the ones in the Corolla. Any help would be appreciated.

Since yours is an '87 you'll have to open the motor up to determine which kit you need. The 85/86 motors had a 5 rib block, 40mm rod big ends, and 18mm pressed in wrist pins (The early 85 MR2 also had a 200mm flywheel instead of the 212mm used in all the other NA MR2s). The 88-89 motors had a 7 rib block, 42mm rod big end and 20mm floating wrist pins. The 87 is kind of the bastard child of both motors. I've had one that was a 5 rib block with the later 42mm crank and 20mm pins, and I've had a 7 rib block with the small 40mm rods and 18mm pressed pins. You'll have to pull the oil pan off, unbolt a rod cap, and measure the rod journal with a set of calipers to know for sure. Also, you will need to look at the series of numbers on the crank, and the numbers on the block to determine what size bearings you will need as Toyota offered like 5 different sizes. You'll look at the crank and it will have 5 numbers, and the block will have 5 - IIRC, in order, you subtract the crank from the block number so if you had 22222 and 33333 you'd use a 1 in each main bearing, but I can't remember off the top of my head. If I had my BGB I could tell you for sure.

You weren't kidding, it is a bastard. I really appreciate the info, but I see myself looking more and more toward just buying another motor to swap out entirely.

Well, you asked about what rebuild kit to buy - they are the same motor as the Corolla which I suppose is the original question you asked. It can be cheaper anyway to buy a used motor. Hell, while you're at it just get a GZE (supercharged - you'll need a motor with all the accessories, and all the wiring and ECU) and swap the bugger in!

Heh, I thought about actually putting a that engine in the car but thats not what I got the car for - it's gonna be my fun little work horse of a car.

I know if I rebuild the engine myself it will be more expensive but not actually that much more, even including machine work. The whole reason I would be rebuilding it is for more of reliablity reasons. If I get used engine I take the risk of it being a junker already, which has already happened with the previous owner.

I'm pondering wether to just start breaking down the engine, because I would have to do it anyways OR sell the whole car. I say that because it doesn't seem that parts are that easy to get at this point. Not just the parts, but information on the car - such as the BGB or even a Haynes seem to be a bitch to find just for those model years.

Is it me or it actually that way?

no, its no just you. I was looking for a Haynes manual for my 87 for MONTHS. I found one and bought it for $30, which in the long run was worth it. Parts are YES hard to find. I mean there are plenty of websites that can sell you re-manufactured parts as well as aftermarket ones. Rockauto.com seems to have quite a bit of things for our cars, you just have to look. And in my opinion, unless its a life and death situatuon, NEVER buy anything directly from Toyota Dealerships! I was looking for a Headlight motor, and they wanted damn near $600 for it, and it was going to be a 4month wait. I pulled the part myself from another MR2 and got it for $5. Just run searches and you will always find something

www.partznet.com is another good site for hard to get items. It is Connicelli Toyota but they are a lot cheaper than my local dealership. As for a rebuild, it is actually cheaper to pick up a low milage JDM motor than it is to rebuild one. I just picked up a 4AGE recently for $500 with a 12 month 12k mile warranty from www.Jarcoinc.com .

Mojomonkey · 02-28-2006, 08:09 PM

Yeah, thats what im looking for right now, a JDM 4age Supercharger motor to swap into my 87. Anyone know where i can get one?

We forgot to mention the learning curve of the rebuilding game. Your first rebuild will probably be a disaster unless you have an experienced rebuilder showing you each step of the process. There's even a learning curve in doing a J-spec swap. J-spec dizzys, sensor, intakes are different than USDM. Also they don't have an EGR system, which would be a problem if you live in a insanely over-regulated place like Kalifornia.

Mojomonkey · 03-02-2006, 10:07 AM

yeah, thats where i live. Smog restrictions are REALLY stiff. But if you watch what your doing and know what the laws are EXACTLY, im sure you can find a few loopholes and what not.

I have a 88 S/C MR2, I bought it out of a swamp for 700 bucks and have rebuilt it to good running condition. I had new plugs and wires put on, new relays put in, and had the ECU rebuilt, now i'm going to have the motor/tranny and supercharger rebuilt, but I'm having trouble finding out where i can get the supercharger rebuilt, any ideas?
