A few weeks ago I picked up my new track day car that I will be keeping a build log on .



It’s a MK3 MR2 facelift 2003 that had the 6 speed gear box .



The car is in great condition with no to very little rust under the car and divers very well indeed .



I was looking at an MX5 but the problems with rust have just put me off and I like the MR2 better ( I did run a MR2 REV 3 Turbo )



The plan is to build it up ready for next year where we will be going to the Ring again but will look to take in some UK track days as well .



Plans are Suspension coilovers , ARB , tyres , brakes , exhaust , induction , bracing and any other things along with some weight reduction .



The T sport 190 BHP engine swap is said to be easy so I might look in to that later .



The car is 975 KG in stock form so I plan to get this down to around 930 KG



The car is now sat in the garage and will be until the new year but first thing done is a Mat performance chassis brace .

subscribed!!! it'll be nice to see another red mk3 on track smile

I picked mine up 3 months back (after also previously owning a tubby) and i've done 2 days at thruxton with it pretty much stock! like you said, any mx5 around the same price are rustbuckets, on paper these mk3's look like and under-rated track whip.

mines pre '02 so I've already replaced the pre-cats with the aftermarket manifold from ebay (it's the same one everyone else sells), thinking behind it was that no point chipping out the crud from the pre-cats that ruin the pistons and then the engine as it would just give more volume for the gas (you wont need to do this, the facelift revision had this ironed out) I then replaced disks for like and uprated pads to yellow stuff, the brakes are REALLY good.

Apart from that I dont think i'll touch it as I was looking to prep it for sprints but regs dictate rollover protection and getting good half cages for these things is annoyingly hard. The steering is very vague even on the limit (i've been told a smaller racing wheel will solve this, disabling powersteering is not a thing here.) and amongst everything else track attack club sell race prepped ones for £3k.

Good luck with your build, The 1zz is a hoot to drive on circuit, these things can house K-20a's if you want to surpass the power from the Celica lump. wink

Good choice!

I just picked up a MK3 a month ago, albeit powered by honda K20.

How did you get hold of matt for the brace?

Was it a black one that was for sale last month around the £ 7000 mark ?

The matt brace came with the car .

Are they hard to get hold of then ?

Nice.

I had one of the first roadsters in the country. Ordered on launch day and I recall it was the 10th customer car off the boat.

First gen were excellent, but they did soften them for the next gen as it was felt they were a bit too sharp for the general public.

Only one of two cars I've had that could be properly steered on the throttle ( by which I don't mean tail out sliding, but trimming the line in a bend by small adjustments to the throttle position). The other was a mk1 mr2 !

Really strong too, the safety cell can take a lot of abuse with no intrusion, but they don't fly too well frown

It was indeed, already fixed a few foibles, and had it on Anglesey and found a few more issues.

I don't have Facebook and see no other way of contacting the chap!

Watching with interest – I bought an 03 FL one two weeks ago and have the exact same plans as you. Haven't found a decent underbrace source yet, thinking of maybe an Ultra Racing one. Sticking some AD08Rs on at the weekend and am currently doing the lambda sensor replacement dance!

What coilovers do you think you'll go for?

Did you weigh the car to start with?

I thought the pre-facelift were about ~975kg, but the post-facelift were 1,050kg or something.. Don't know where the weight increase comes from.

Oh and might be an idea to relocate the battery to the frunk the get the weight distribution back (you maybe have already planned this!)
