Managed to get a few hours on the car today.

I'd had a short shift kit that had just been sat in a cup of or ages, so got that put on and went for the shopping to blow away the cobwebs.

Not so fast though the battery said! 8v's!

A quick jump start and it was fine, whilst it was ticking over and warming up I jumped on ebay and bought an obd solar trickle charger.

Also stopped faffing about with the fuel system and bit the bullet and bought a radium return line.

Went the long way around for the shopping to get plenty of charge back in the battery and it started on the button after being inside.

Some more parts arriving today, radium fuel rail with low profile swivel for return fuel system.

Nice peice of kit, quick test fit and all seems good.

Bored tonight browsing the dvla website to see what plates where about.

Ended up taking a punt on this.

So it'll be known as the STD car from now on 😂

Still unsure as to whether I'll put the plate on or whack it back on one of the sites for resale.

Slow progress due to lock down...

Radium fuel rail has arrived and I've taken a punt on some generic listed 850cc injectors for the 2zz. Had them flow tested last week at the brother in laws and all seem good. I'm still undecided as to whether I'll run them.

For the time being I'll run my 630's.

I'll be running the fuel rail with a return system all AN6, and with a 1:1 rising rate fuel pressure regulator.

All the vac lines that need to go on and that need to be plugged have now been done and a vac block fitted.

Moving on to how the car is currently running, the last time I went out in it my laptop lost comms with the Apexi Pfc, the hand controller worked but no cimms through the FC Hako.

So I ordered new cables, potentially thought I may have shorted the ecu some how when I last charged the battery as I had a short.

So spent a few hours on it today..... And it turns out the laptop had updated and somehow deleted the serial/coms driver!

So after ages messing about swapping cables, checking grounds etc it was just a case of reinstalling the driver! FML!

Anyway all connections are working now and logging as they should do.

On the bright side I tidied up all the ecu cables and usb's etc.

The plan is to when I swap the engine to run it in using the the apexi pfc map it's currently on even though or for a 1zz.

Reason being I know this map works, I'm familiar with the platform should it need any changes.

I also need to get the engine underload and driving as soon as possible after starting it to get everything bedded in. I don't want the hassle of learning a new ecu at the same time and potentially hampering that short window I have to bed the rings in.

After its been run in, I'll then swap over to the Emu Black, start turning the boost up and see how we go.

Then it's new turbo time.... I've got a generic GT3076 and GT35 on order to see what they're like, both currently stuck in Germany! If they're pish I'll look into Holsets.

Haven't updated this in a while!

Well both the chinese turbo's I had on order never turned up.

But did manage to get a replica GT3076 last week and and seems OK. Standard ebay turbo, internally gated with water and oil.

Car wise, the car has been sat scorned for a while, whilst it has I've done a flat floor and fitted an S1 elise diffuser to the rear, so will be interested to see how that goes.

Manifold wise I've been in two minds for a while whether to run my current cast manifold as it's drilled for 1zz and 2zz applications, however the exhaust ports are shaped differently on the 2zz and are more oval than the 1zz.

I've been in two minds whether to press the button on an OBX manifold on ebay for a while, but decided against it this morning and I've ordered the radium racing one which was developed for a lotus 2zz turbo kit.

Plan is to get the car MOT'd in the next couple of weeks and finally get some track time booked soon.

Another years MOT done yesterday, picked it up this morning 1st driving it in a couple of months.

Once warmed up gave it some beans... God I missed this car!

Hopefully be out for a run in it later on and get some updated photos.

A quick shake down and everything seems to be holding up with the flat floor and diffuser.

No drumming, rattles or knocks.

With this power they are phenomenal on b roads!

Bonnet catches and Button catch keeping the bonnet down nice and snug on the headlights now too.

Not much has happened recently,  but here's a walk around video for them asking.

Great day yesterday at Blyton, car performed flawlessly.


Flat floor and alignment working fantastic.

So much so that that two Kswapped Elises even commented on how quick it was in the corners and just couldn't stay with it.

Wet in the morning and after lunch, but plenty of cars there drying the circuit out.

Thank you for sharing that, enjoyed it very much. 

So a bit more on the changes I made since the last track day.

1.Got rid of turbo gasket, used flat surfaces and a smearing of exhaust paste.

Result no blowing gasket and no loose turbo bolts at all.

2. Flat floor and rear diffuser, noticeable difference in corner speed and grub, this combined with new alignment made the car feel so well balanced.

3 degrees camber on the rear and 3.5 on the front, zero toe front and 0.1" on the rear.

Next up I'll be swapping over from my Apexi Pfc to my Emu black on this engine to get used to mapping with it and work out any bugs before I look to drop in the 2zz.

Some from this weekends track day.

Another quick update, easier to do to this way!

Sooooo, I've been looking at my EMU Black and looking to get this fitted and running on my 1zz before I go 2zz.

I've had a look at my plug and play loom.

I've gone back to RRR, with a few queries as it doesn't quite seem plug and play.

The wideband input is via a deutsch DT6 connector so looks like a need an adapter loom and even though the IAT sensor is pinned into the loom, it goes back into the large roadster white plug, which has got me thinking do I need to add something to my Roadster loom or modify it, depending on where its been pinned to in the roadster loom.....

Looks like the loom is going back to RRR for a quick check over 1st before installing.

So I've just been busy enjoying the car really.

I have however managed to come across a very well priced lotus evora gearbox with linkages and cables etc.

First trial fit of how how the bell House adapter plate will need to look and so far looks pretty straight forward.

I've got it located on one bolt at the moment which will be the reference point.

I'll either get these scanned and a plate made or it should be simple enough to make a timber template.

Next is looking into flywheel and clutch combinations.

These are from a couple of nights ago, now in 18mm ply before going to 1/2 aluminium.

So far so good.

Just waiting on some Auris gearbox mounts to come in and driveshafts.

Done a few bits away from the gearbox this weekend.

De-pinned the deutsch work style wideband plug that was on my Ecumaster loom and re pinned it for a standard bosch Lsu 4.9.

Bought a few bits, some new Injectors from Dave ID1050's and a new rear crash bar.

Plan is for next week to get the car running on the Emu Black on wastegate pressure, then introduce the boost Controller to get used to the software.

Then swap the 2zz into it in the coming months.

I wouldn't mind picking your brains sometime Gary over a brew or a pint!!

No problem you're only over the hill.

Another thing I'd forgotten to mention.

I had ordered a radium engineering 2zz turbo manifold.

I'd ordered it from three different places all saying they had stock, anyway it would seem its now obsolete!

Which isn't really an issue as the cast manifold I have is drilled for the 1zz and the 2zz.

But.....the 2zz has oval exhaust ports and the 1zz round, so wouldn't be a perfect port match and I'm not 100% sure there's enough material on the manifold to match them up.

So I've ended up going with a turbo kits. Com manifold for the time being, it also enables be to get everything mocked up on the engine before it goes in too.

Have you looked a twobrutal surely someone has adapted the gearbox already. Certainly there are mr2 V6s with 6 speeds.

Yeah I've been on and had a read, it's more of a long term project.

So the car is now officially running my Emu Black.

After sifting through loads of base maps to get a feeling for how the software works, I loaded up a modified 2zz base map.

And she firs up first time and idled much smoother than the pfc used to.

I've got an issue trying to get the lambda sensor to get a reading, but luckily I'd bought a spare to just run the ecu on.

So I took the 5v output from my AEM and ran it through one fo the spare analogue inputs into the Ecu to run it.

Haven't been for a run in it yet, I want to spend some time going through the protection parameters, it does move under its own steam though.

Plan is to tune it on wastegate pressure, then add in the boost controller.

Good work
Looking forward to seeing the project progress further

So been for a quick run/log in it.

Quick change up on the VE table to get it nearer to where I wanted it on boost.

Next time out I'll switch to it reading the target lambda tables.

Software is taking a bit of getting used to after using the Pfc for so long.

Very confident now that this will start up and run the 2zz, to get it ran in before taking it for tuning.
