Shipped Timing Belt and Cam Gears off to Engine Shop yesterday, they should receive them today or early tomorrow.

Still hoping to have the engine complete by November.

Engine's finished and valve clearances checked out A-okay.

Will be picking it up tomorrow. Hopefully can finish assembly this week.

Ordered my new ECU today:
- Adaptronic e440D
- Innovate MTX-L Wide Band Kit
- Flex Fuel Sensor

Should arrive sometime next week. Just need to work out what size injectors I need and get a Oil Filter Relocation Kit.

Some nice bits of kit there.

Do you have any evidence that you will need larger injectors? See as these injectors are the same on the US turbo car, I would have thought that they would have sufficient headroom to handle even a solid NA build.

might be enough, consider the E85 too.
i would rather grab a set of WRX injectors, cant remember for the life of me... think 440cc?? or something, and they bolt onto our rails, plug in and are nice and cheap
i bought a set from Mad mat years ago, then passed onto andy.

220 engine Hp @80% duty = 360.94cc / 34.38Lb/Hr

for E85 see below

34.38 x 1.47 = 50.54

= 530cc

now this should give you some idea of estimated injector size on e85.

i dont know your actual target Hp... but just selected 220Hp at random.

Edit: All above @ 80% duty... good to leave some head room

On E85 with bro's evo we have 1100cc FIC injectors.

E85 @ 260 All Wheel kW.

final tune put the 1100cc injectors at about 79% duty

also question... why run a flex sensor?
Cant you do dual maps and just push a button switch from 98 map to E85 map?

from the specs

"dual maps which can be toggled with digital input."

just thought it would reduce the dyno time... not totally farmiliar with the adaptronic... seems pretty wicked from what i can tell.
does the "flex sensor" just need 2 maps to be made, 1 for E one for 98? and it "learns" and auto trims for anything inbetween?

or more like the Gm unit which chooses one of 4 maps (which ever is closest)

if its the learning type... awesome!

but if GM type then thought the toggle input would reduce dyno time and cost

EDIT: apologies for the tripple posts... I get excited about ECU's and electronics lol

I think those are some ambitious numbers there.

The stock 280cc injectors will handle 180hp at 85% duty cycle. This is a more realistic hp number on 98ron and 85% duty should be ok as he has little scope to upgrade or significantly improve what he already has

This is just what the guesstimate figure from a formula which every injector company will tell you to use as a guide

Thanks

Other then the Injector formula below no. And its somewhat confusing due to the reasons you mentioned. Only real reason I'm getting bigger injectors is for E85 as im skeptical of the numbers that Injector companies have come up with.

Aiming for ~170 at the wheels. Which is about 190-200 at the fly I think.

One reason is that the most common form of E blended fuel is eflex which can be anywhere from 70-85% blend. Obviously the resultant octane level varies based on this, with the sensor the Car knows what % ethanol is in the car.

In regards to what its utilized for with the Adaptronic. The way the adaptronic works from my understanding is that with the presence of the Sensor it works out the ethanol content and adjusts the fueling requirements based on the ethanol. Its possible I believe from a few posts that the maps are able to blend.

i.e. I stumble across a servo with E85, get a tank full. Drive somewhere and want to top up before a mountain run or track day or whatever. Traditionally I'd be sweet out of luck if no e85, what happens is that the fueling requirements alter so that as I head towards a lower percentage concentration it adjusts the fueling etc towards the 98 octane map.

The way it does is simply done via a table that it looks up. I'll see if I can find some screen shots. Haltec do a similiarish thing AFAIK

180 Hp at the fly or wheels?

The other thing that we are neglecting is that I believe the Injectors we utilise are originally from an RX7. The Denso 440cc (WRX Injectors) are much newer and are meant to have a much better spray pattern.

I've been told the MX6 injectors are an upgrade too as well. Not sure how reliable this information is, personally taken it with a grain of salt.

This is why these ecus are pretty sweet. I'll do the same once it's running. It adjusts on the fly altering the ignition and injector maps.

those injector companies calc's are definateley inflated. lol

I actually sent Mat a link to Injector Dynamaics excell calc table today. takes into consideration more factors, and seems to be most accurate.

also remember... boosted cars require different sized injectors to an NA.
example, in that formula... multiplier for 0.50 - 0.55 for NA and multiplier for 0.60 - 0.65 for boosted.

Personally... my call would be to use the Subie 440cc injectors and to up the rail pressure with adjustable FPR for the added compression.

So by the sounds of it.

2 "base maps" are required.
your 98 map, and your E85 map.

then looks up fudge factor table for the flex fuel compensation, as well as a trim learning ability.
Which is awesome... nice ECU choice seems the winner for a standalone !

CSR E85 is pretty hard to find.

we are mostly made to use United and caltex Eflex. still good ****... wayyyy better that 98 that's for sure lol!

An interesting concept and not something you'd prolly ever hear on this board is that I might be under camed.

Things I still need:
- Fuel Pressure Reg
- WRX Injectors for E85.
- Pick a Tuner
- Fuel Pump for E85

List is in priority of stuff needed. Not sure anyones really reading this but what are peoples thoughts on using GTAe gears + triple cone synchros for first and second?

GT-ae Gears:
3.454:1
2.187:1

FS Gears:
3.307:1
1.842:1

Overall ratios would be:
3.454:1 (GT-ae)
2.187:1 (GT-ae)
1.310:1
0.970:1
0.717:1 (GTX

Means that at 7700 rpm Id be dropping back to 4500 rpm. Based on LW posts on Twiggy Cams that's right at the start of the power band. Not sure what my power band will be like at this stage, so unsure if this will be a good thing or if ill be going on cam to off cam and have some lag.

Darryl, as the resident twiggy cam owner. Thoughts?

Twiggy cams should kinda start at 3,000rpm but prolly don't really open up until 4,500rpm.

It might be worth getting your engine in and going before cracking the gearbox open and putting shiny stuff in there. At least then you will know how the engine behaves and what your powerband is

agreed

though, the GT-Ae gears will be very nice... 1-3 gears are shot peened, a close ratio setup will be so nice for a high strung N/A motor

you don't really need to use a GT-X 5th gear, you can get a USDM 626 5th gear and it will also work, but I suggest a USDM Protege 5th gear instead in order to maintain your 5th gear highway torque
