Car was painted by a fellow MR2 owner and personal friend of mine.

All the issues are sorted with the car although it's changed set up since the last update. And I have more plans to come.

Just realised that it had been a while since I last posted anything.

Car has been through several changes and is currently undergoing more.

I went to a trunk mounted intercooler set up. Original plan free air from under the car, and out the back between the tails.

I also finished up the wheel re-furb and had a go at making my own exhaust.

Since those pictures, I have fitted coilovers and white line swaybars. Now drawing air from under the car doesn't work as well so I'm changing up the intercooler, it will draw air from the side vents and out the bottom.

I have also removed the interior to strip the sound deadning and removed the OEM turbo and manifold to upgrade, so watch this space ;)

I've started decides to re-do the loom as well with all this spare time. It's amazing how much wore you can remove and have everything still running.


Also, here is a little teaser for anyone actually reading/watching ;)

The OEM puts in quite a few things that are required to meet manufacturing rules of the times and adding features that are nice to have. Some things are there that a lot of people don't understand are there for a reason of a car that the manufacture is trying to sell as a quiet reliable drivable car. You wouldn't want to buy a car that didn't have AC, smelt funny because of no emissions gear or was noisey. Well at leas the people buying the cars new from the dealer, rather than someone 30 years later and the 5th-10th owner. OEMs don't care about people like us.

Now that's a real turbo. Definitely keen to see where this goes!

Sadly won't be able to fit the turbo untill I have a manifold made, which will not be started until after lockdown.


But I've been keeping busy. Have the location of the turbo somewhat sorted. Plan is to run it with the compressor side facing the original intercooler ducting. I will make up a blanking plate and use the intercooler shroud as a cold air intake. Also shortens my intercooler piping buy roughly 400mm or so.

I made up a blanking plate for the passenger side vent as I'm going to duct the air to the intercooler in the boot.

Will try post updates as I tick things off. But covid has me running out of parts/things to do very quickly.

Beautiful block off plate. The ones you get with the Greddy style intercoolers are terrible. Don't fit well and do not block off the air going around the intercooler. I'll be sure to make one like yours but have the intercooler hole in it and seal it with some decent rubber seals. That's good inspiration for others. Thanks!

I like your design and can understand the dynamics of using what limited air flow source is available. Keep in mind the hot exhaust including hoses in close proximity that need some decent air circulation. Not sure if your plans include a top fan on engine lid but might be worth consideration.

You are right Jim. Need to consider the air flow of the MR2 engine bay. Up from the bottom and through the side intakes/vents and out through the top and forwards towards the rear window. Take a look at the direction of the vent louvres on a stock turbo engine lid. The face forwards, not backwards. Are goes from over the roof, drops down at the backlog the engine lid, circulates forwards the back up the window and then out the top.

There is a video a guy posted on YouTube showing models of the MR2 versions in a water flow bath with nitrogen bubbles acting as smoke like a wind tunnel. It shows this exact roof to engine lid circulation phenomenon.

Once I have the manifold I intend to make up some heat shields to help keep heat away from sensitive areas. I also intend to wrap the downpipe (and probable mid pipe) to keep heat in the exhaust and out of the engine bay as much as possible.

As for the air circulation in/out of the engine bay, I am currently mocking up a custom "engine lid" of sorts. although it isn't really an engine lid, it will replace the lid and side panels.

I'll post pictures of that once I have finished it/once I'm happy.

Have talked with Sinco customs about my manifold and once they are able to go back to work we will begin mocking things up.

List of things to do is still long but slow progress is still progress.
