Corolla manifold on a Starlet EP91, more hp

The easiest way to get more power is to get 4efte, and replace all togehter. But here in Sweden there are no turbo Starlets... so cant find any.

This post is a bit messy, I am trying go gather facts and opinons about the diffrent engines, so bear with me... :)

Inlet manifolds from the following cars should fit on a naturated aspired 4efe.
4efte, 5efe, 5efhe, 4efe

Three versions of th 4efe has been made:

First generation 4E-FE

"The first generation of 4E engines found in the Starlet GI, Soleil and Corolla models were produced from 1989 until 1996. The engine found in these two models produces 88 bhp (66 kW) at 6,600 rpm and 86 lb·ft (117 N·m) at 5,200 rpm. This engine had more in common with the 4E-FTE, sharing the same throttle body, and slightly larger fuel injectors." - http://en.wikipedia.org/wiki/Toyota_E_engine#First_generation_4E-FE

Second generation 4E-FE

"The 2nd Generation of the 4E-FE was introduced in 1996 producing less peak power: 74 bhp (55 kW) at 5,500 rpm, but with a slight increase in peak torque 87 lb·ft (118 N·m) at 4,400 rpm. The 2nd generation of the 4E-FE was essentially the same engine as the first but the intake and exhaust manifolds were changed along with a slight alteration of the ECU meant to reduce exhaust emissions."

Third generation 4E-FE

"In 1997 the intake manifold was changed again along with the ECU and the result was 85 bhp for the Corolla and 82 bhp for the Starlet. This engine was discontinued in 1999."

"4efte's can be bought cheap these days, if you have a EP91 NA and you find a Glanza V engine then it's really easy as the ECU is plug and play"

I think this Corolla intake manifold can be mounted on a Starlet EP91 4E-FE engine and can give some extra horsepower?

"4efe from a JDM starlet (starlet Gi or Glanza S) has bigger injectors, a different inlet manifold and a more aggressive ECU" - Dave

UK Spec 4EFE - 74bhp
JDM 4EFE - 100bhp

"The Glanza S has 85 hp"



I am trying to gather information about the diffrent versions of more power there are of 4EFE.



I think this versions is what most swedish corolla 1.3 1989 to 1996 with a 4efe has.

I think this engine is from an 4efe corolla?

Ralph1: "I need all the air intake plastic bits and vacumm lines etc?"

From what I've heard there are thicker rods in these engines, and stronger valve springs.

Thanks to FrozenJakalope for answering questions on ukstarletowners.com

1. The swap of the intake manifold between 2nd and 3rd Gen 4E-FE is just straight forward replacement - correct? (all the hoses, cables etc stay where they are? The existing bracket holding the inlet stays and fits ok?)

Yes to all of the above except the small hose that goes to the MAP sensor will be slightly too short. Think it's a 4mm silicone hose you need, can be got on eBay for less than £2 posted.

2. What is the inside diameter of that intake - will it fit my existing standard throttle body??? (is it 45mm?)

Exactly the same as the standard N/A throttle body, same sensors and size.

3. If I change the Mani only do I still get better airflow? Is it worth investing in 50mm throttle body and what car is it from? (do I have to port the mani then?)

Yes, the shape of the mani and smaller chamber is where you get the gains. It would be a massive ball ache to change the TB as well because of the sensors. I think the 4AFE TB is the best bet if you really want a 50mm one, but then you would need to port the inlet to get gains and they'd be minimal. Not worth the effort imo.

4. Do I have to change the ECU (after changing Mani only) or just overnight reset would do?

Your ECU will be fine, you don't even really NEED to reset it, it'll adjust itself within its own tolerances over a couple of days driving either way.

6. What is the most advantageous set up for this tubular inlet?

No different to not having the mani. This one is literally just an improvement, anything else you'd do to improve the car in your eyes will still improve the car. Bigger exhaust for better throttle response and so on will give the same gains.

7. After fitting this tubular inlet only - Is there anything I MUST do?

Make absolutely damn sure you've got the vac lines and coolant lines on the right way round. We've all done it at some point since the hoses are identical, but if you put them on backwards you'll pump coolant straight into the cylinders and best case is you have to sit there for 10 minutes while the engine sharts it all out of the exhaust. Worst case is you hydrolock it and pop a rod.

"I fitted one to mine and it all pretty much swapped straight over"

This is the intake you want. Found in Glanza S or Corollas with 4e-fe engines."

tubular corolla or the 4efte inlets are the 1s to go for

Dont know if this will intake will fit

Toyota Corolla 93-97 SOHC 1.8L 7A-FE Engine

jezza323 (http://austarletclub.com/index.php?/topic/9466-help-intake-info-for-a-4e-fe-ep91/page-3)

early 5efe manifold = 4efte manifold = 5efhe non ACIS manifold = early 4efe manifold

late 5efe manifold is basically the same as late 4efe manifold

and then there is a weirdo glanza 4efe tubular one

and the 5efhe ACIS one

tubular 4efe and late 5efe/4efe are good for torque, low rpm

all the rest are no good on a stock late 4efe because a stock late 4efe cant rev  

--- answer from Starlet_rich_uk ---

Don't know much about the differences between early and late moddels but heres my understanding

4efe(starlet)/5efe(paseo) = standard manifold (good torque)
4efe(glanza s)/Corrolla(ae111 euro) = Tubular = better peak power not so good for low down torque
4efte = Good for turbo with the shorter runner
5efhe ACIS = good all-rounder long and short runners (rare) 

 

Riko666 ( http://www.ukstarletowners.com/topic/7411-getting-more-power-from-non-turbo-4efestarlet/) gives this guidelines:

"in a naturally aspirated car there's only so much you can do...no idea how many times I've posted this but whatever, these are typical options:
- 5efhe Transplant (or just take the connecting rods, block, pistons, camshafts)
- Good Ignition System (Uprated Spark Plugs, Spark Plug wires, Coil)
- Proper Lubrication (Correct Oil, freer flowing Oil Filter)
- Uprated Radiator (plus coolant additives like Redline Water Wetter)
- Corolla Tubular/5efhe ACIS Manifold (port & polish it, extrude hone, ceramic coat...)
- Phenolic Intake Manifold Insulator Gasket
- 7/4AFE Throttlebody (port & polish it as well...)
- Heat-reflective Tape wrapped intake piping and freer flowing airfilter shielded from heat
- Tuned Tubular Exhaust Manifold (Ceramic Coated)
- Freer Flowing Tuned Diameter Exhaust System
- Decat/Freer Flowing Catalytic Converter
- 5efhe/Custom Camshafts
- Thinner Metal Headgaskets
- Lightened Ancillary/Crankshaft Pulleys
- Lightweight Flywheel
- Headwork (port & polish, extrude honing, x angle valve jobs...)
- Lightened & Uprated Valve train (lighter valves, spring retainers, stronger springs)
- Lightened Internals (Pistons, Connecting Rods, Crankshaft)
- Cylinder Boring (0.5 - 1.0mm overbore)
- Internal Friction Reduction (friction coatings & processes on internal components)
- Piggyback (eManage) or Standalone (Motec) ECU
- Individual Throttle Bodies"

He mentions 5efhe ACIS Manifold also. I have to check up on that.

Xpect: "Well ECUs are obviously different. Injectors too but I don't know which exactly are to wich Gen. So I state what I know.

The Corolla EE101 (4EFE Gen1):
88ps in europe, due to better fuel up to 100ps in Japan
Inlet: bigger, same as FTE (in fact FTE is based on Gen1)
4-2-1 exhaust mani (in two parts, for adapting on a starlet welding and a flexpipe are required)

Starlet and Corolla EE100 (4EFE Gen2):
75ps
4-1 exhaust
Higher compression
Smaller inlet mani
Thinner and lighter conrods at same strength as Gen1

Corolla EE111 and Glanza S (4EFE Gen3):
86ps (also up to 100 in Japan afaik)
Tubular inlet
Apart from that, ECU and injectors afaik same as Gen2 (Starlet 4E)
Some have different ignition setup
The Glanza S engine has a different fuel rail with higher pressure"

rmsnoel:
"Put a 50mm throttlebody off a 4afe corolla on a tubular manifold. It matches up right and the throttle sensor is a sensor.

Our uk gen2 is a more refined version of the gen1. The gen1 92-93 had 88ps with a up n down torque curve and 6500rev limit, the jdm had a higher limit hence 100ps. The gen1 used a 50mm tb and fte type manifold and the 4_2_1 ex manifold. It also had slighty more lift, slighty. The injectors were average squirty things and it had normal fuel pressure.

The gen2, our uk engine has 45mm throttlebody, longer AND narrower inlet runners and slightly, slighty less lift on the inlet cam. I believe to improve torque over the whole range. Bhp is also 10hp higher over the range until we hit our lower 6500rpm limit. The exhaust is a 4_1 type, its alot cheaper to make than the 4_2_1 but theres no evidence that it is better or worse than the gen1.

The gen2 also has a better type of injector- more missy spray than squirty squirty. It has a throttle sensor for more accurate tuning for mpg than the basic on off switch on the gen1 and fte. The idle control is on the tb instead of the manifold mounted gen1. It has 75bhp and is in the starlet and in corollas from 1993_1997 roughly

The bugeyed corolla is basically a gen2, although it has a tublar inlet manifold, this gives it 86bhp, same as when u put this manifold on your starlet! If you measure the runners they are bigger than all the other manifolds in diameter. If you measure all the demensions and get your little sister to do the maths like me youll see it uses some ram effect induction.

Then gen3 also has this tubular 86bhp inlet manifold. It is even more refined for emmisons and stuff than the uk gen2. It might have a 6800rpm limit. It uses coilpack ignition, a knock sensor and crankangle sensor to do its business. It has a 45mm throttlebody.
