So some more progress.
Clam is now on and secured
Indicators are on top of the clam tested
Fans are tested
Side lights are tested
Main beam is partially tested.

This is where I started having fun. The drivers side main would work. Excellent news.
The passenger side wouldnt. Easy ! Bulb out ! Swapped the bulb over to a spare , nothing.

Multimeter out , another spare bulb out , nothing!

Balls!

Known working bulb from drivers side into the passenger side cue retinal burn.
Swap the two spares over to the drivers and nada.

Best get some new bulbs then hadnt I?

Spent an hour and a half dicking around with that.
 
Today I have mostly been doing lights, archliners and regretting doing the arch liners are I forgot my lenses were not attached ...


I purchased these as the H1 was knackered. So put in a new set. Also did the H7 because I really, really dont want to get the car back together and then have to take apart again for lights

I have a couple of bits to fit to the car to aid in differing areas.

Firstly I have a mishimoto thermostatic oil plate. I already have the lotus one on my car but noted that my oil temps seem baltic unless I am really going around track. From reading it appears that the Lotus stat opens at 65.5 deg C and this one opens at 85 deg C.

This can only help with things in my opinion regarding oil temps

Ill ask the fine gentlemen at SeriouslyLotus to fit this for me. When I cant find them I am sure John will. Car is due a service so seems perfect timing

Second thing I bought after deliberating for an age is a larger throttle body. The TB I have on is currently 65mm and this one is 70mm.

Its been killing me that another car made more power with a very , very similiar setup. I am not one for chasing numbers ( liar , liar , pants on fire ) but this was bugging me. Where was I "missing" out?

There are a few minor differences between the car that made 300bhp and my 282bhp such as exhaust manufacturer and injectors, slightly different charge cooler pipe work but nothing really major. The only "real" difference I could spot was that the DBW throttle body is 70mm and the cable body 65mm.

Got to be that, right? I guess time will tell. Ill get the new mishi thermostatic plate fitted and then fit my uprated TB and get over to RSTuning for some tweaks.

Some pictures of a not very exciting TB

Yesterday I booked in at SeriouslyLotus to get the car serviced. I am taking my lunch with me to eat it off the workshop floors.

I have also ordered and collected 3 new screws from toyota for my new throttlebody so I can detatch the IACV and attach it. No doubt I will butcher the old screws so safter to get new ones. I have a gasket already .

Ill get that fitted around 19seconds after returning from SL and get it booked in with RSTuning to get a map tweak to discover if the expensive, reading , research and hypothesis was worth the "missing" HP
 
You want to go & see Scoff at EFI Tuning....
:punish.gif:
I trust Paul @ RSTuning.

He has tuned many of my cars ; My R26 in all its guises and it stayed in one piece despite me hammering it , my c63 got great numbers and stayed in one piece, my exige has also had great numbers too and despite my best effort on track - its in one piece!

I would never advise jumping between rollers either. So many discrepancies there.

Remember though its not about the peak figure, heck I could tune anything to beat any tuner in the world peak figure. Might just do it once mind ...
 
Today I popped over to Seriously Lotus to get its annual oil/filter and bi annual brake fluid chage No dramas there.

We did stop at fitting the Mishimoto though for three reasons
1) Fittings
2) Oil flow direction change
3) The guys that designed/built the mocal stat think its stuck open.

So , rather than upset the apple cart Ill get a new stat and o ring fitted in September / October whilst having a few bushes changed out.

Easy!

Car running well and thoroughly enjoyed what is normally a rather mundane motorway schlep.

My quest for aero performance has turned up this :


car_photo_222550.webp

I am going to check to see if I can see any figures for my GT4 look-e-likey rear wing to compare downforce.

I appreciate its never going to generate f1 levels of downforce but every little helps and this is the internet after all.

I have the front splitter to tart up and get to paint, then Ill get that fitted. I am also looking for details of any tangeable benefits of adding some front end wheel arch vents to remove all the air.

Its diminishing returns I know and I know I am not a racedriver etc.

Any / all input is appreciate, even if its Andy you have had enough internet for one day.
 
Tonights task after a moderatly positive day at work was to remove the old throttle body , split the IACV from it and refit all the gubbins onto the new TB.

Throttle body conviniently placed here at the end of the ITG filter

5 million pipes removed. Various fittings were taken off and sworn at as every single time I needed the other socket. 7mm this time Sir? You will need the 6mm for this clip.

A single 12mm and 3 13mm nuts and voila. TB off. Someone has been here before me and bodged it. Why is one a 12mm? Why is one a threaded bar and the nut is stuck to it to clamp it down? Pretty sure the thread should stay in and the nut comes loose..
Anyway , its off. I plugged up the two water pipes underneath with some of the finest bolts known to man from my spare "Renault 5 GT Turbo spare bolts" tin

Lets grab the tape measure just in case I already have a shiny new 70mm TB fitted and I just wasted my money. Pictures dont do it justice and I dont have a vernier gauge. Its 65mm on the top TB and 70mm on the bottom new TB.

At this point I gained a supervisor. To be fair he is less hairy than some of the supervisors I have had before.

Now here is the money shot. Old TB stripped and new TB with the bits on.

I must confess I had fun with two parts.
1) the spring loaded twisting mechanism to return the TB back to "stop"
This was a riot. I undedid the screw gingerly and then oh so gently tool off the quadrant. Cue a spring doing the great escape and flinging its way 1/2 way across the garage into the spider wastelands. I did debate just ordering a new spring from Toyota and let the spiders have it. However I took a brave pill and got the spring

2) The IACV screws.
I knew these would be a bastard to get out. My screwdriver(s) would not dig into the slightly knackered posi head. Someone had been here before so I ended up drilling the heads, slipping about a jillion times and wacking the heck out of it with a cold chisel. Got there in the end. Not my finest work but unless you are John you wont see it. Changed the gasket over on the IACV , cleaned up the IACV and put in three new Toyota screws. I noted that the IACV had a magnetic part to it. I found this out as all the swarf was stuck to it. Cue more cleaning.
 
In tonights episode of I did a thing ..

I drained the ProAlloy catch tank.

Thats 3 years and about 8000mi worth of oil. In terms of trackdays - 11.


For anyone reading about swapping over a throttlebody I would strongly suggest putting the TB on but not doing up the top nuts and then putting the clips on the sensors next. Then do the bottom bolts and do the top nuts up tight

I risked life and limb next and started the car with the airfilter off. I have never heard such slurpy slurp noises. I was concerned that the contents of my garage would be enveloped by the new TB.

I was wrong but it sounded delicious all the same



The only casualty of this was the carbon monoxide detector which kept on squarking even though the garage door was open.

It found a new home in the garage fridge for a bit

Idle is a little high - perhaps as a result of me cleaning the IACV and perhaps due to a new shiny TB. Either way Ill get the laptop out tomorrow evening and start some page down on the target idle RPM.

Best get some mapping booked in
 
Make sure you fit the filter before doing the idle can make a difference.

My boss spent a whole day tuning an e type the other day with out the air box. Thinking it would be fine without. Unfortunately he was wrong. He changed the carb needles as it was lean in places. Once he fitted the air box it was rich and had to revert back…
