The exhaust mani is a 4-2-1 corolla mani its a rarer part than the inlets as people didnt think to take them off before they scrap them unlike the inlets which got removed

Nice find there. 

I've got a turbo inlet cam here if your interested in installing it. It has more lift giving better mid range to topend gains. It would suit your setup. From wat I can gather not alot of people know about this. You would be the first to run it I reckon. 

They are super easy to install as well. 

I can put pics up to prove the difference with a micrometer. Just because there are disbelivers on here 

I spotted it off the dyno graphs. It stands out a mile tbf. 

Yeh there very good.

Also handy when road mapping. Which I always find better than dyno mapping. Real world environment. 

I'll put up a how to road map your car and what your looking for over the course of a year, running threw the four seasons as well as altitude change. 

Has any one run one of these. I'm thinking of ordering it ASAP with the Honda listed sensor that will screw directly into the engine block were the 4efte knock sensor goes

Nock gauge.  Bellow picture and link. 

Other gauges I've installed 

Fuel pressure. 

Boost pressure 

Exhaust temp

Wide band lamba 

All with peak and minimum alarms set. Analog and digital readout displays

nock/det detection devices.

You are doing a great job with the gt. 

After looking at figures from the leader board the ct9b and hyb give alot more torque, pull from what I can find they run a less restrictive turbine. 

If you put a fuel pressure regulator on this now things will get mega. The fse regs are some of the best I've found. Avoid the cheap ones on ebay there really poor. 

Those pictures 😎

Give us a list. I did see some were a list of options it was crazy. 

I've got the CD model power windows electrical sunroof central locking and rev gauge. For the age of the vehicle it's really impressive.

Thanks but no thanks bud I can’t be bothered messing with cams it’s not where I want to go with it 👍

😎Looking good. I really need to get mine in the body shop ASAP. I had no idea how good these can look. 

Waw that looks really nice. I think might be developing a soft spot for the gt turbo. 

Yeh I've been studying it recently looking at the difference in hp against torque on all setups. 

What I'm referring to is the difference and relation ship between the 2 on the same car as well as on different cars/setups of the same hp and around same hp different engine 5e/4e. 

For instance look at Ryan langs 4efe hp and now more importantly reference his torque massive now find the nearest 4efe closest to that and whats does its hp read. There's somthing different about his setup unique and ill tell u now his torque curv will be till near redline. That's the car I'd won't to race. Now aply this to others. Now research and speak to people. This approach saves time and alot of money. 

By looking at the torque and not hp in the leader board you will uncover the 5e engine for sure. Then look at the dyno graphs very impressive. Hp and torque side by side. 

Now finally look at the easy hp gains a 4efte can make but torque not so much. 

The 5e is the other way round telling me the 5e has a larger stroke and not a increase in cylinder diameter this is massively important when mapping because the piston will have a slower acceleration past tdc and thrs not alot that can be done about ignition timing will be procise and critical. What helps confirm this is the previous comment and problem with ignition timing setup my advice is run a Very good ecu. with coil on plug if your turbo makes big hp in a small rpm band. Be warned running a piggy back ecu on a 4e ecu will 99% spell disaster. 

We had this very issue tuning the d series Honda engine. 

If you beef up the pistons and rods and pushit, it will take out the big end or crank.

thanks mate, i awlays upload on here want to keep this forum alive haha. 

I do like the  build Information.

I wish do wish people would get more dyno evidence or the site had a setup and dyno graph topic. 

The torque is amazing from the 5efte it has a very good crank to rod ratio just becarful about the hp hit surge. These engines don't like to rev hard/sharp (hp hit) its to do with the crank to rod ratio. 

The 4e is better for hp but the 5e is a beast true torque. 

I'm going to try and get the same torque levels out of the 4e I've just got to tame the hp surge so the torque can be used put on the road. 

Really nice work. 

Keep them pictures coming. These cars are great to work on and learn on. 

No way.😄 These cars come with some stuff. I've been looking at the optional extras you could get.

I don't but I believe I am right in saying 4efe and 4efte cams are the same, its only the 5efhe cams that are different. 

I've got them both here they are different more lift on 4efte. I'll post pics up tomoz. Just the inlets. 

I've been looking at this very topic over the past few month. 

I'm recently new to the starlet group and 4e engine. The lad I got ep91 CD UK starlet off showed me a graph of his 4efe tuned to 118hp with a great torque band of nearly all the rpm band. 

His spec 

4efte inlet cam higher lift. 

ROLLA tubular manifold with plenum extended and 1991 gen1 ecu to match the 4efte throttle body 

4-2-1 exhaust manifold off a gen1 corrola 4e.

Ported head (mild) and exhaust and inlet valves dereztricted 

2 inch exhaust system 

Mx5 1.8 red injectors

Power box, and cone filter induction. 

Fadanza 4kg alloy flywheel and low anertia clutch

68deg thermo 

Platinum heat 5 plugs

Racing ht leads

As well as things like power steering remove 

Improved engine earthing 

Fse fuel reg. 

Charcoal filter removed and tank vented to atmosphere. 

Aem piggy back. 

From what I've seen thr are 2x ways to tune these both with different results and power feel. 

The first way is the above way only people have failed to spot the na 4e cam and overlap restriction to topend hp. The turbo inlet cam or 5ehfe acis cams help from factory. 

Or the gen1 4e corolla approach using the

4efte power inlet

A much smaller throttle body from wat I can see its around 20mm less diameter to help low down flow power rates also helping throttle sensativity. 

Brown injectors 

4-2-1 exhaust system. 

I've found 3 lads on here runing this second option 1 being Ryan lang on the leader board you can see his engine torque difference he ran the 4efte throttle body hitting a impressive 86hp but 1 of the biggest torque levels. This is the pulling feeling. 

All of the 4e cars In here run the 4e na inletcam. 

More to come.

Thanks Pete 

Do you know if any 1 run the different 4efte Inlet cam in a 4efe. The na cam is stoping gains over 90hp it looks like. 

I need a graph of the 4efte cam on a na 4efe engine. I can't find 1. 

Did I see you were turboing urs.

I didn't do anything to this na engine. My first starlet I did, its an old build thread so pictures may have gone but the info is there. it made 86.4hp with corolla inlet, mr2 throttle body and slightly bigger injectors 

Thanks Pete

QUESTION: for any 200+hp runners. What's your mpg figures please and hp. 

Thanks in advance. 

WANTED COROLA TUBULAR INLET I'VE GOT 100 QUID WAITING. 

Go on there. Great stuff. 

What power did you get from the na engine. And a graph and mods if possible.

Really nice work 

It's a really y easy install cam  belt stay on take around 30min. I cam send you a how to. Also if your interested. Get it haha. I can show you the drop off of power mid range due to the rolla inlet plenum chamber size (small) and pre throttle pipe restriction. 

I need to see a n/a graph running the turbo cam for my setup options. That's why I'm offering. 

Do you know about the 4efte inlet cam. 

Would u be interested in giving it a go if I sent you 1. 

The first to do the mod from what I can see. And a good chance of hitting 90 to 100hp. 

Good strip down link, you can see here the size and quality and quantity of the bearings in the six speed box alot stronger. 

Im running this gearbox  c160 bzr

It's my first starlet turbo and Im really. Very impressed. I was just reading up on the gt and glanza box and must admit its a strange gearbox the gear gaps are some of the biggest I've ever seen. It's got me alittle confused. 

I think the 5th gear is a economy overdrive only gear to bring down cruz rpm at 60 70 80 mph. Japan run a strick 110kph speed limit, which is a god send for these cars. The car shape and design will hit a massive drag resistance around 120mph requiring big hp and torque to increase speed past this point. 

The long gearing Im puzzled at with a ct9 stand system I can only ashume it was seen to be unsafe with shorter better accelerating gears and diff. Combo. Which no manufactures want the cars to be know as killers. 

From the information I've gathered the corrola c series gearboxes are the best ratio's for acceleration but topspeeds are lowered. The c series box design here in most examples is heavy car/ small engine cc. These gearboxes will also increase reliability, they have the capability to reduce engine loading if used effectivly. With the c63 and c64 and C160 the exception. The C160 is geared to improve torque because the 4age produces high hp low torque levels. 

The c64 and c63 being true short racing boxes and the best option in my opinion. The fact its found in the lotus the example. 

Is any body running the 63 or 64 gearbox I need to talk to you.

What's the plans for the engine proformance. 

Jesus there is a few forged engines melted pistons at high hp levels on here. 

Top speed engine killer these boxes. The shape of these cars are not for high speed. The engine coolant system is out of its depth it looks like. 

Just reading about these mls head gaskets. Shocking design some of these mls head gaskets. 

I've got some really good information on engine block coolant pressures against engine rpm. Things like coolant pump cavatation and using restriction plates rather than thermostats. 

It's all to do with engine thermal efficiency and load. I run a closed back impella 4e water pump to stop cavatation.
