As my car draws nearer to finally being completed my main concern has been with the chassis.
I have put a 2litre turbo in a car from the 1980's that was only ever ment to be a 1litre with 60bhp.
So after some careful consideration and some sound advice, I've decided to have the engine bay reinforced. Gussets will be used in all the weak area's so that it may handle the extra weight and power. The engine mounts will also be revised.
It's not been an easy decision to make as everything will need to be removed in order to do this job, even the dash has to be taken out. It's going to set back the completion date and cost me more money. But all is not bad news, we hope to have it done by Christmas.
Here are some pics I've taken today...
(Stripping down is now in progress)
The reason I don't want to use a roll cage is because I think it might ruin the standard look I'm trying to go for. Depending on how elaborate the cage is, they also make general use hard work too, "getting in and out of the car". I would also like to keep the option of having rear passengers as well.
It is difficult to try and photograph the following work. So below I have drawn a plan view diagram of my engine bay. It shows all the extra material that has been added to my bay in order to support the bigger engine.
The dotted lines represent multiple plates surrounding the engine mounts, multiple gussetes, one cross member from front to back, one front supporting bar, one upper and one lower strut brace.
Here is the engine back in its bay. Only finishing touches left now before I take it to get mapped.
I don't have any power targets at the moment. My goals are just getting my car back on the road and making sure everythings built to a good standard. I will be more than happy with anything +200bhp to begin with. I think my current setup should be easily capable of that.
But having said that. I plan on upgrading the intercooler, fuel pump, injectors and exhaust. I'd Like to be running more like +300bhp figures eventually.
Been checking out the factory weight of the k10 model micra. According to google its stock weight is a mere 635kg!
I plan on taking my car to a local weigh bridge after having it dyno'd. I'm interested in finding out the exact weight with SR20DET installed. Then I'll be able to calculate the precise power to weight ratio.
I'm so excited about these wheels. I've always wanted to put a set of these on something. They are very rare. Specs are 14x7j offset -10
I had to remove the tires in order to give them a thorough polish with different
Gradient polishing disks. They was in a terrible condition when I first bought them. With curb marks on every wheel. They was badly oxidized and had no decals or painted centres. So after many hours , this is what I ended up with.
I will be putting these wheels on my car soon. So more pictures will follow...
Wow, you're brave chucking that amount into the project.
The usual- you could have got 2jz power for that etc is not really applicable here - if you take into account the fact you've paid to have the work done to save hassle/time and you've ended up with a little cool fast car. I mean what else could you spend it on for circa 300bhp per ton?
I've spent fair money on purchasing high end JDM cars but I've always done the work myself, which can go one of 2 ways and usually involves a lot of late nights and swearing but is of course rewarding IF it gets finished.
You've gone all in to get the job done how you wanted and that costs money- like anything it depends on how you look at it and what you want out of it
Unless you're planning on selling it on you'll get your investment out of owning it for a long time hopefully.
It made 224hp on the dyno. It was only limited by the maf sensor. So I bought a new maf to take it up to around 300hp. But ended up selling the car.
I had one or two sketchy moments and was put off by the thought of crashing such a small unsafe chassis, with a high powered engine. I could have put a roll cage in it and invested another 2-3k before being totally happy with the build. But by that point I was 2 years in and down by around £11000 to date.
It broke my heart to sell the car after investing so much time, money and effort. but the new owner seemed lovely. I hope its running well for him and being looked after.
I ended up purchasing 260hp mx5 after my k10 sold. It's been fun but unreliable!
So now Ive wiped my hands clean of old turbo motors. My mx5 is up for sale and I've just put a deposit on a v8 manual m3.
I will probably buy another k10 in the future and when I do I will be sure to let you guys know!
