ok, this is just a place holder for questions that ill come up with for my conversion..
Basically, im going to put this..

into this..

Basically, i know ill need custom gearbox crossmember (will probably run the engine on low boost with a w57 unless i find enough funds for r154)
custom engine mounts
Bonnet mods to allow for bigger engine
modified drive shaft

I assume i have the smaller r180 diff in there at the moment, will an r200lsd be strong enough for 300-400rwkws?


cheers

Why the fuck would you bother?

Put a 1j in if anything, 7m's are fucking horrible motors!

7M > SR20 ... but a 1J would be the best choice, motors are cheap, and are much better than the 7M.
in saying that, 5M > all of the above.

Put it in a toyota if anything, nissans are fucking horrible cars!

after seeing his other thread, his celica/supra got fucked up so I think it's just the engine he has, might as well use it

although all the money spent customising the s14 to fit the 7M could probably trick out the SR20 anyway...

Might be able fit the 7m in with out bonnet mods.. Are they much taller than a 2j? My s13 fits a 2j with no bonnet mods.

I love the 7M's, but only in the car they came with, if I was ever going to put a Toyota motor in anything I'd go with the 1/2J option.
Unless you have the cash of Rigoli to be fucking around with them (7M into R32) then you are wasting your cash, even if you have the motor spare, but a cheap ass cressida if you must and bang it in there.
But for the cash it's not worth the effort.

RB25, the engine that a Silvia should have come with.

No shit, keep it inhouse if you can.




7M is a fucking stupid idea, its ALOT of work just to do a head-gasket. If you want a toyo in it for the sake of it, 1j would be the best and cheapest option. Marty has 17 1j's sitting on shelves at the moment, less than 1k for everything...

Its the same for any other engine, head has to come off, actually an SR20 is a bigger prick I seem to remember.
Anyway, redundant point, Needs more RB or SR

I've met a few of you 7m Fo lyfe ppl... It only lasts until BHG or big end rattle. All the best, but as stated before just 1j it.

I have my engine already. Despite the 7m hate around my engine has been fully built up the way I want. I've spent far too much money on it to sell it and buy a stock inferior replacement.
I didn't ask for who thinks 7ms are shit. Please keep things on topic.
S133l do you have pics of your conversion?

Just saw one crammed into a MX5, so can't see space being an issue.
Do you have any of the mountings from the donor car?

deaf_rattle
29-12-2011, 09:18 PM
Yeah got mounts from donor and from s14.

if they can fit a supercharged 1uz in a mx5 - they could probably fit anything

Yeah but thats only 4 cylinders long.
You know how long a bloody 7M is!

there is nothing wrong with the 7m, slap a good head gasket in and some head studs(torqued down correctly) and you have a decent motor

Look I guess it depends on what you've done to your 7m... but on paper you are telling people you want to pull out a lightweight aluminium motor that in stock form makes 216hp and with considerable difficulty replace it with an older iron block motor that makes 232hp.

so that's why people are questioning the conversion, especially when the rb25 would be easier to wire in and fits using r33 bits if you really want the displacement

iluv2moan
29-12-2011, 10:43 PM
there is no reason why his motor cant make a reliable 450-500 rwhp as it stands but... lets see a stock sr do that...

at the end of the day he has a motor which he has probably spend over 10k on which is good for 500 hp and would be worth sub 3k to sell if he even could...

makes perfect sense to remove a stock motor which he could easily sell off and replace with his fresh motor...

did 7ms come with a front sump in some cars??

Ive got a build thread on silviawa mate but you may have to be a member to veiw it.. Not sure.
If you want tp pm me your email and when I get home from work next week I'll shoot you some pics.

Keep motor on the side for donor MkIII, run S14 as is/RB25 conversion?

Heaps of MkIII going cheap, even an Aerotop with a blown motor sold on SupraWA FaceBook page for $1k. Not a bad way to buy one and slap in your worked motor etc. without the considerable headfucking and shit. Don't know your financial position though as to why you'd go down this route.

Annnnnnd this is when I check your location and realise you are in NZ so my post is null and void anyway... all the best with your conversion!! :)

As for the conversion, fucking do it.

More to it than just the gasket. There is also an oil pump and cooling issue.

oil pump? not getting confused with a 26 are ya?

Marti
30-12-2011, 11:49 PM
Surly there would be a good aftermarket oil pump for it ?, or are you talking about oil pump and water pump causing cooling issues ?

7ms are known for running big ends.. usually 5 and 6. The gears on the factory pumps are freakin massive and are comparable in size to truck engine oil pumps.
With increased sump capacity, sump baffling, knife edging of crank, smoothing of block internal I think I've taken care of oiling issues.
Also the 7mgte runs a high flow low pressure system, so with regular oil changes, decent filter and thermostatically controlled oil cooler. Delivery shouldn't be a problem.

its the 7mge that gives the 7mgte a bad name, different head gasket, if you used a 7m gte head gasket on a normal 7m with correct torque(as stated before) it would probably never do a head again

you could put that 7mgte into a cressida for about $1000 and thats including buying the car :P
may save you a big headache, but if your keen on doing it then go for it, at least it'll be different, i always get people shaking there heads and questioning why i put a 1uz in a cressida then someone else would come along and say its cool and different, but hey its your car not theirs :)

Yo man... a mate crashed it for me. Rather nice of him. Pics in showcase.
Will get rebuilt with a 1uz and a few more tricks later on.
Hows you? Been a while.

ok, so ive been looking into things today..

Upgrading diff? will the stronger r200 type diff bolt straight in? or will i need different shafts as well?
also, with the fuel line on the drivers side of the car, whats involved with moving it to the passenger side where it will need to be for the new engine?

cheers

S133LTR
01-01-2012, 04:52 PM
Diff will go straight in, driveshafts will bolt up provided you use an r200 with the same bolt pattern on the output shafts (there are a few bolt patterns within the s1x family).

I looked at moving/re-doing my fuel lines in my car but in the end it was just as neat/effective to use the stock lines and the make new hard lines in the engine bax which run up and over the fire wall to the lhs of the engine bay where the toyo rail is.

deaf_rattle
01-01-2012, 05:00 PM
cheers, yeah i had thought of that, but would rather try and keep the fuel lines as far away from the hot side of the engine as possible,
will do that to get it running though maybe.

S133LTR
01-01-2012, 05:22 PM
Yeah thats what I initially thought too but the s13 only has a half chasis rail on the lhs so there is nothing to protect the lines (s14 may be different). If you go down the lhs maybe box the lines in? Ive insulated mine with fire proof sleeves and sheilds and have no dramas but full new lines down the lhs could def be done.

Damn that hurts. Oh well, on to the S14 :)
Things are good except I have no horsepower (S8 FD RX7). Hopefully change that soon?
Will keep an eye on the S14 thread

well ive been looking into this further and found some pics of the conversion being done. Will post them up soon.
Hoping to get the supra in the garage soon to start pulling it apart (selling parts) and still have my parts s14 sitting there too.
Stand byfor progress, will post up in my project thread as i make more progress. cheers
