Indeed, its a long term project, I don't plan to sell the car and it will be a learning experience for me as well, I know that parts of this project will be quite demanding but its ok as I can SORN the car if needed, its not my daily drive, I think the MOT is up in December but might look to get parts on the car sorted and then MOT it in a month or 2 as its then not in the middle of winter if if needs work!

After owning some older cars I am slightly disappointed with more modern cars that aren't user serviceable, they usually have a massive piece of plastic over the engine and usually need to be plugged into a dealer only PC to do simple jobs. Having owned a 1982 mini that can be fixed with a hammer, screwdriver and a spanner, along with a few mk1 MX5s I am wanting to simplify everything as much as possible.

I have decided that I want to simply improve the driving experience of the car meaning I can look at certain parts quite subjectively when looking to remove weight, example being the central locking door motors - yes central locking is good, however it doesn't help with the driving experience.

Plan for this car will be to build up a built engine with an uprated gearbox to hold some moderate power without breaking so I only need to put an engine in once.

Started preparations for the initial drag runs, will be taking off the hardtop to run with the standard soft top for the 'as delivered' weight, I have also refilled on fuel, I have filled the tank to the brim as if I brim the tank for this run and then brim the tank when I reduce the weight I will have a consistent amount of fuel each time. The drag time would be slower as I might be running with 30kgs more on board but it means that I can take the fuel variable out of the comparison as it wouldn't be like for like if I ran with slightly different fuel loads each time. Once I get a baseline with a reduced weight I can then run with less fuel to get a faster time.

I also brimmed the tank when I bought the car as I was wondering what sort of MPG the car does, since I have had the car I have had some commutes to work - mixed speed limits with roundabouts with some dual carriageway, brim to brim the car took 30.5 litres after traveling 286 miles - this works out at 42.6 mpg (unsure if this is good or not!).

Mods currently on the car:

High flow drop in air filter
Brake cooling hose used as cold air intake (instead of mkIII pipe)
Removal of pre cats in manifold
TTE exhaust
Tein lowering springs on new stock dampers

Better mpg than I ever get
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

Take is that that's a good MPG then? I took it steady coming back from collecting the hard top and have only really revved it up a couple of times, although there was a fair amount of idling whilst checking the Dastek which was running rich!

Hard top has been taken off now ready for Saturday, will probably be the last time the car has a soft top fitted, still need to order the rogue solid mounts.

Have you got it setup incorrectly.
As in litres instead of gallons of km instead of miles.
Also you want imperial gallons not US.
I use fuelly and think it's great.

I thought I had but possibly not, I put it down to only putting in two, part fuel ups so far and it not having enough data yet.
Do me a favour Scott, list for me your settings please and I'll double check mine..

No matter what I select the result is still the same but I've only done 300 miles for £50 over 2 part fuel ups so I think it still needs more information.

Will be heading over to Santa pod in a bit, for reference the car at this point is at the 'as delivered' weight, although I have also put the OEM heat shields in the passenger footwell as those would be fitted in a stock car if it had an OEM manifold.

Current mods:

High flow drop in air filter
Tein lowering springs on stock damper
Decat manifold
Dealer fit TTE exhaust
Dealer fit TTE spoiler
Stock ECU (not taking the Dastek today)
Softtop but with hardtop fitting kit attached
All interior trim including tool kit, spare wheel etc

'As racing' all up driver weight including keys/wallet/phone/shoes etc - 81.6kg (so I can take this into account the next time I run in terms of weight reduction).

I will also be taking a portable tyre compressor and a bottle of water - will weigh both of these as well, I also don't know if I need a helmet as it technically an open topped car so will be putting one in the car although won't be running with the roof down etc.

Thanks, just sitting in the queue right now, fair mix of cars today, didn't need the helmet as I'm not running with the roof down. Will get as many runs in as I can to see what a very lightly modded MR2 runs.

Best run so far is 15.97 at 85mph, also another run at 15.98 so consistent, and that's on a 175k miles on the engine on a very hot day here. Have done 5 runs, lifted out of one but all are 15.9 to 16.1 so very consistent to get a good baseline.

+1. Doesn't look like too many horses have escaped in those 175k miles.

I have just got back home, here are the results from 6 runs, its very hot out there!

Run 1

2.3044 second 60 foot
16.0027 second 1/4 mile
86.88mph terminal

Run 2

2.4065 second 60 foot
16.1749 second 1/4 mile
85.06mph terminal

Run 3

2.3435 second 60 foot
15.9728 second 1/4 mile
85.56mph terminal

Run 4 - missed 3rd, aborted run

2.3704 second 60 foot
16.3858 second 1/4 mile
78.55mph terminal

Run 5

2.3618 second 60 foot
15.9813 second 1/4 mile
85.07mph terminal

Run 6

2.2833 second 60 foot
15.8627 second 1/4 mile
86.86mph terminal

The last run was the quickest at 15.86 seconds, but its amazing how consistent it was earlier on, looks like on the last run I had a much better launch shown by a better 60 foot time, I also held it in gear slightly longer and held it at the top of 3rd I think as its at the limiter near the line.

The car does have a short shifter which I believe has helped quite a bit and actually the lower power is helping the traction down low as I only get a tiny bit of wheel spin off the line before the front end lifts lol. Today I beat to the line: a custard yellow Seat Leon Cupra R, a fully stripped out civic hatch (with those expensive drilled out rear arms), Mitsubushi GTO and also was keeping up with a highly modded Skyline until about half way (till the turbos kicked in). Just goes to show how nimble and light off the line the car is coupled with the short shifter and close ration 6 speed box - was quite a bit of fun.

I have now started to remove some parts from the car, I will also weigh the helmet that I didn't need, also took 1.5 litres of water with me and the air compressor, was also running an almost full tank - still have just over 3/4 tank left, looks like the stock tank takes 48 litres meaning I am still carrying probably 35kgs of fuel still so can easily remove say 25kg from the car by running with less fuel.

What the total weight removed then Mitch?

Need to get a different set of scales - probably the fishing type scales to then hang some of the parts, might be about to roughly work out a few things using bathroom scales though. Looks like the spare wheel is around 11kg, even the doors to the rear bins are a couple of kgs, will make bigger gains once I remove the passenger seat at some point - won't be all the time though.


I have just taken the car out and found that it feels much more nimble and has a better turn in, there is additional engine noise as I have removed the rear parcel shelf and rear trim but its not that bad. I have remounted the OEM alarm siren onto where one of the bolts go for the frunk well (where the wheel goes), seems fairly sturdy. I do however need to address a few bits in the frunk area as its not seen the light of day in 14 years!

Sounds good progress  s:) :) s:)  I'm considering getting rid of a lot of interior stuff that's not used and having a general purge of weight. Starting with the soft top since it's not been used in 3 years - I always use the hardtop, though I could consider running neither on days when I know it's going to be dry, or having a really light shower cap for when it's parked.

Yeah, its getting there, been holding off on all this until I had a benchmark run in to get some indication of what it was like as stock, the aerial has had it so I am removing the radio and the speakers etc, think that will add up to a fair bit!

Its actually quite simple to take apart so far, mainly those poppers and a few bolts here and there, nothing complex at all, just in the process of looking into the intake setup, its a shame that the stock MAF pipe is part of the airbox - will have to look into other options I think.

Interestingly, plugging in the ET from today and guessing at power at 140 bhp its showing that the weight would be at just over a ton, or its guessing at around 150bhp if the 'mass in transit' figure on the V5 is used, still fairly happy with the time today even though it was very hot.

Just pulled another 2.454kg from the doors in the shape of aftermarket speakers (Alpine type S) and the stock tweeters, no stereo in the car so no point having those, each door card seems to weigh around 1.5kg, will keep them initially but might look to change to lighter door cards.

Also, I am taking some inspiration from the below project video, ignore the terrible music, but check the progression from stock running a mid 15 to a low boost turbo, to 1 bar boost on forged then again on 20psi running a high 11 second pass, aware that the car isn't about straight line speed but you can always dial down a turbo whereas today I felt the car was losing a bit of top end power.
