New engine options for MR2..? Newbie needs some help!!

[mr toyless]

Hi everyone, I'm currently looking at options for my next project.. I've been offered an 84 MR2 5spd for really cheap, the only problem with it is the factory red-top is getting a little "tired"..
SO..
I would like any advice on possible replacement engines and the amount of other work needed to fit them (ie gbox, mounting, wiring etc)..

Ideally I would like to keep the car NA for now, although a 3sgte would be a S**TLOAD of fun.. I've thought about a 20v conversion, would this be worth it or am I just wasting my time..?

Have been away from Toyotas for a while, my first car was an 84 MR2 with a fairly standard red-top. Really keen on getting another one to replace my current daily drive, the almighty Honda City.. Lol..

Anyway any advice would be much appreciated..

for a 84 i'd imagine the origonal engine would have been a bluetop, not a red/black top.
anyway.
Have a search around.
Lots of 20v conversions done. afew 3sgte's, 3sge's and obvously supercharged as well as turbo'd 16valvers.
All bar what you already have will mean wire/loom changes (and mount changes for non 4age). The 4age's mounting wise will be virtually the same (except maybe one mount on the ze)

The other aspect is how much do you want to spend/have to spend and how much can you do yourself?

Ooops my bad, both MRs were 85s, and mine was definately a red-top, but whether it was original is dubious.. The owner previous to me performed a very dodgy 5spd conversion..

Intending to do quite a bit of the work myself, aside from some of the wiring.. Budget was originally around $3k but would rather spend a bit less an keep it stock-ish for now..

The other question I had was can a 16v gearbox be fitted to a 20v engine..? Or could i fit a black/silver head to a 16v block..? Or am I just getting myself in too deep to start with..? So many questions..

If you're -really- wanna get in too deep, check out the toyota 3L v6/mk1 swap. A couple thoroughly detailed writeups on the net

May depend which box. Im not sure if there will be issues with starter clearance on a 20v.
for 3k i'd stick with a 4ag' series engine, but if doing most work yourself you can do a bit for 3g.

The 20v will fit on std gearbox, and the headers will JUST clear the std starter motor. This is if you have a c50 gearbox (the early verison). If your lucky enough to have a c52 gearbox then you can bolt the starter onto the intake side of the motor, and there are no problems at all then.

(just did it this morning )


If I were you, I'd do a 20v conversion (but i am baised...).

Easier than a turbo 16v, and having a high reving na motor seems to suit the aw11's personally better than a flat out power machine.

3vz-fe or somthing, FlyingBrick is putting it into an SW20 so its a bit different.

Ahh oh ok. Just saw mr2 and thought sw20:D

For an aw11... Id like to see something really high revving. Oh wait its already got a 4age... Dont worry then. Just invest heaps in your 4age so you can rev up to like 10k

Or 3sgte, 3sge are options. Remembering by changing engines to a bigger capicty and mounts etc. THere is a lot of fabrication required and if you cant do it yourself you better have a big wallet.

What about something like a Aw11 with a 1jz or 2jz and its Rear Mounted like a porsche.

Off Topic: How do RR porcshes work. Is it like a FR but just backwards ?

Thanks everyone, yeah I think I'll sitck with an NA 4age at the moment..
Will have to start having a hunt round to find a decent cheap one..
On that topic, what are the main differences between a silver-top and a black-top..? I know the black-top has the quad throttles but are there many other differences..?

[bluemaumau]

blacktop

[slighty_sykotic]

Silvertop has quad throttles too.

Ive got a blacktop in mine.


Differences are in the blacktop has higher compression, better head design, bigger throttles and is map sensored. Makes more power.

they both have quad throttles, blacktop ones are just bigger

blacktop has slightly higher compression
silvertop = AFM, blacktop = MAP sensor
blacktop revs slightly higher
different intake plenum design

other difference is about a thousand dollars in price

hehe im gonna go out on a limb here and say

is it possible to put like a b18c or h22a in an aw11 ?

Why?

the motor spins the worng way/mounted the wrong way
