is it worth doing?

silvertop 20v into an ae92 fxgt?

only thing i can think of needing to be done would be the wiring?

surely would be alot better than 88kws of tvis fury?

[Gadget]

ohh poor you, you lucked out and got the 88kw version... they also came with the 100kw redtop...

If I was you, I wouldn't pith about and find yourself a good blacktop...

Talk to Distrb, he's done Blacktop 4AGE into AE82 and swears by it....

[Mr Revhead]

a blacktop will cos theaps more though unless you get a deal (distrb got a DEAL)

for the retail of a b/t you could buy a s/t and rebuild it to take boost the overall job would cost a little more, but give far more value for money.

what it really comes down too, is whats your budget

I will hopefully be able to let you know about this in a few weeks time, as that is exactly what is happening to my car currently. AE92 T-vis motor, being replaced with a silvertop 20 valve.

Don't ask me complicated questions though, as I'm just the driver not the mechanic

I gather (so far) that I will be looking at another radiator top tank as well, and possibly a new throttle cable, as neither of these line up terribly well to the existing blue top positions.

[Distrb]

Hmmm lets see....

Radiator will either need modding or replacing due to the location of the bottom hose on the bottom tank being at the very end (passengers side) of the radiator. Existing one causes difficulties with getting the right diameter bottom hose connected without it kinking horribly on the way.

Throttle cable and mountings could need modding or replacing as its a wee bit too long. On my 82 it was easy enough to modify the mounting/tensioner, so we didnt have to replace in this case

The existing power steering pump bracket may need to be modded if you have to use it on the s/t, same with the alternator bracket. If you use them, you need to splice the plugs into the s/t looms

Existing gearbox, flywheel, clutch, fuel line, fuel filter, sandwich plate, starter motor can be used if required, although would reccommend getting a b/t flywheel and a new clutch kit.

and then there's the rest of the wiring...

you ask "is it worth it?" well..... what would make it "worth it" to you? what would you expect from it if you did this conversion?? whats your aim with this car?

[deaf_rattle]

well ya see i have the red top tvis in there at the moment, it is quite nice to drive, but im abit bored with the power (probably because of the supra)
the current motor leaks oil pretty rapidly and the gearbox is on its way out. it has also done 230000kms

so im left with a few options

replace the motor and box as one

replace the gearbox and fix the oil leaks while im at it.

do an engine conversion


what do you think?

[Fandango]

To tell you the truth dude, dont bother putting a 20v in unless its a blacktop. Stock silvertops aint much more fun than the 16valvers.

I would get a non tvis 100kw, lighter flywheel, extractors, cold airbox.

Only my opinion tho.

[Mr Revhead]

a silvertop will piss on a tvis engine.

and will be cheaper than a blacktop by heaps
blacktops are like 4agzes, waaaay overpriced

[Malcolm]

I agree with Mr R.
The silvertop is an excellent choice of engine, particularly for something lighter than an ae101, as they can be had ridiculously cheap (like $250 for a running donor car), and make nearly as much power as a blacktop.
I have been thinking about a silvertop into the corsa for a few months now, and fully intend to do it if I have the time and can handle life without the corsa for a week or so.
Will be a very easy conversion and if you're smart about it you should be able to get away without a cert aswell

[NZ_AE86]

'All_Fours' You might be dreaming about that but if you can get some running 20V vehicles for $250 then I will take 4 please!


But back on topic I think you would be better off spending the money on the 16V if you are going to race it. But if you are going to drive it daily then I would say it would be better to do the 20V silver or black top.

[Leon]

I picked up a silvertop, ecu, and loom for $500, but they tended to be more like $700 - $1000 from some phoning around.

Hopefully in a couple of weeks, I can tell you if it was a worthwhile transplant

This is going into a road legal, clubsport use Corolla. So not really built with racetrack use in mind, but will see the track occasionally. Definitely not daily driven.

[Dell'Orto]

Can this be true - deaf rattle considering a 20 valve?

But yeah, if I were you, I wouldnt bother fixing the old motor and box, its just as easy to transplant a silvertop, and would be a fair bit peppier

[Mr Revhead]

enlightenment comes to most ppl eventually

[Adamal]

Well, there's "enlightment", and then theres "practicalilty" isn't there?
Its easy to get the two confused

[quinny]

Blacktops havent dropped in price at all since i brought mine 2 years ago and now knowing what a full conversion costs the silvertop sounds better bang for buck, i just have a hatred for AFM's, i managed to get the blacktop and 6sp noted on my wof sheet as fully legal and not needing a cert so the 20v's are the way to go

[JT]

I think you will be disappointed with the silvertop, they have shown to be ~8-10kw less at the wheels than a blacktop, both in standard form.

Silvertop would obviously be better over the 88kw 16v, but blacktop is worth it IMO.

[quinny]

well i am certainly not disapointed with my blacktop, worth the extra if you can afford it i reckon

[deaf_rattle]

yeah, unfortunately i am considering the 20v
however this idea is brought on, because the fx is a daily driver, so reliable power is what i want.
The 20v would be more suited to a lighter chassis since they are torqueless wonders.

Ideally id like a 4agte, but in all honesty that will never happen as the extra money would be better spent on the supra.

and silvertop power would be alot better than 88kws of tvis doom

[Mr Revhead]

plenty of talk in a 20v!

ok so you want a reliable econoical repower thats better than a 88kw tvis engine and wont cost the earth, as is a relativly straight forward job.
silvertop it is then. yes the black is better, but still not worth the extra cost imo.

[SIDE_FX]

ive heard silver tops dont mind a bit of boost like the old 16v good old japanease cast iron but yeah turbo 4age's are and their reliabilty are a personal opinion, if u want a box i have one $100
