Converting AE101 Levin to Blactop 4age

[DXROLLA]

Hey im guesing this may of been covered but ive had a search i cant come up with anything?

Im wanting to know if this is a relatively simple conversion, with a good gain?
Whats all needed for the conversion?
Does the black top ecu plug into the standard silvertop loom with just changing the afm or is the complete black top loom required?

Also what are the different gear boxes that come with the different model levins? What seems to be the strongest has factory lsds.

Any help would be good or point me in the right direction to past post as i cant seem to find much.

Thanks Hayden

What is the point?
For amount of work there will not be a good gain.
You will gain about 10hp if lucky.
Far better selling AE101 and buying AE111, they are slightly lighter as well.
You can do it, but it involves a lot of wiring, other than that it is just a bolt on (with 5speed box).

Sweet as thats all i wanted to know, cheers for the advice

You can ask Acesniper about this.

Regarding gearbox, AE101 are C52, AE111 are C56 if five speed and C160 for 6 speed. The difference between C52 and C56 is the gear ratio (Correct me If I am wrong). But it will bolt straight up no problem. From memory, facelift AE101 are also C56, not 100% sure. are you looking to turbo it or just pure NA? if NA a C56 will be good I think. If turbo, I think you will need a E series gearbox (Correct me if I am wrong again). For Factory LSD, I think there is a code after the gearbox that can only be found on the chassis plate. Check the FAQ section, I think is in there

The loom will be different (Acesniper can tell you that).

Why do you want to do it? wouldn't it be easier just to get a blacktop head and swap it with your silvertop one? Silvertop rods are stronger too so if you want to rev it, silvertop rods would be better. The only difference between Blacktop and Silvertop is the rods, quads intake size, size of intake plenum, the head (I think from memory), and one is AFM and one is MAP.

Are you looking for huge power increase?

[Mr Revhead]

^ also pistons

best bet is to keep what you have
fit a link or other tunable ECU (see chaosad's thread on his plug-in megasquirt) and go from there, a good tune will really wake up a silvertop

swapping to the blacktop head would not be the best bet at all, they are not all they are cracked up to be. and definitely not worth the effort swapping to one.
make sure you have the better ae101 ITB's, with the better intake flow

[xsspeed]

c5x-04a = open diff
c5x-04c = lsd

unsure for the eXX boxes.

Rev: Better flow velocity due to narrower diameter? Any idea what bolting up ST ITB's to BT would do? Do the ports match?

[Mr Revhead]

there are two types of ae101 ITB's
or more accuratley two type of inlet manifold
got some pics somewhere... i'll dig em out later
one is a better shape

I don't think the ports match, but i reckon it would work quite well if you port matched them
the black top ones are HHUUUGGGEEE. too big for a 1600

the single biggest advantage the blacktop has over the silvertop is the tune
the stock tune on the 101 is not the best, you can get massive gains just by doing that alone. more than you would by putting on a blacktop head

some pics of my dyno plots there, done same day back to back. pics are of the best of 2-3 runs on each ecu
ignore the actual figures for anything other than a reference to those two plots..... the dyno was waaaaaaaay under reading

[Mr Revhead]

btw fittign an E box to n/a 4age is just wrong

[DXROLLA]

Awesome cheers for the info, the car is just going to be my daily and the odd track day im not looking at turboing it or anything drastic. A year or so ago i had a b16a civic and i loved the way it drove all it had was intake lightened flywheel and a bit of an exhaust, so what id love would be for the 4age to match that and i would be stocked unsure of what power it put out though.

This will be my first 4age ive owned so am wanting to learn everything i can about the car (AE101 Levin) and the engine, as in whats possible whats not and what works and what is just a waste of time and money.
I like the idea of going to say a link ecu as you can get rid of the afm and it opens the motor up to more serious mods later on if i feel the need ( which always seems to be the way with me )

I pick the car up on Saturday so i will beable to see how the car goes than it has a pod filter and full 2 1/4 exhaust. When i get it i want to do cam belt water pump new spark plugs and a good all around service mainly just for my piece of mind.

[Mr Revhead]

putting the stock airbox back in with a K&N filter would be my first step
they lose power with pods

[xsspeed]

Cheers Rev

+1

+1,000,000

[DXROLLA]

Yes il be putting the air box back on aswell, the pods can f#$k you afm to cant they?

[xsspeed]

If you need an airbox and can't get one locally I have one sitting in the garage

[DXROLLA]

Could be keen il have a hunt around the wreckers here first, how much would you want for it sent to ChCh?

[xsspeed]

$15 or so plus post would be sweet by me for airbox, think I may even have some of the associated intake pipes that supply to the bottom of the airbox if needed.

[DXROLLA]

Yeah that sounds good il give you a pm when i get the car so i can see what it has and what il need

[AceSniper]

Pod is no issue if you have it setup right.

Facelift silvertop 93/94 have the better intake manifold and c56 gearbox's.

A Blacktop can be bolted in and pluged up to your stock silvertop loom but doing this you will have to run the afm
Blacktop loom/ecu can be wired in but if your paying someone todo this save up and get a aftermarket ecu.

Blacktop has a big advantage over the silvertop with ex port size

[Mr Revhead]

im not so sure its a face lift thing or not.... however my memory of the details is hazy my 91 had the better type.

pod needs supporting mods... just putting a pod and intake on a stock silvertop does not get you any where

yeah it has an advantage in ex ports... but the gain from that is bugger all unless you do supporting mods.
and when you take into account the combustion chambers, better off to port the silver top exhaust side and stick with that imo.

[AceSniper]

port it for steam injection via the water gallery
Guess it depends what your after

[Mr Revhead]

hey water injection is a good thing!
