I agree with what Jay is saying, keep it simple, what you are proposing sounds pretty complicated. have you thought about the hydraulics of the whole system, position of pump etc?

you are going to have big issues with servicing the system (access in the side vent areas in particular) in the future in the event of a leak etc. whats size HE are you going to use?

so pretty

Firstly, you are both saying that it is more complicated, but I reckon it is comparable to having a front mount HE. I don't think running hoses across the engine bay is any more difficult than running them to the front of the car (and in fact I think it will be even easier, when the engine is out).
I can see how having the barrel in the boot/trunk is a little more complicated than having it in the engine bay, but I don't mind losing some boot space, and it would be nice if I didn't have to squeeze another big object into the engine bay.
The other benefits of having the barrel in the boot are A) it isn't as hot as the engine bay, and B) I can fit a really big barrel (as Jay suggested). The barrel that I've got is bigger than it might sound, so I'll probably just try it and see how it goes. At least having it in the boot means that I can swap it to a bigger one easily if I want to later.

I'm still open to your thoughts on this, I won't be offended! :-P

The complication is actually more towards the mounting & pump location than the hoses. Not to mention you'll be paying more in fittings, paying for an extra heat exchanger (+ mounting). If you had a look at the hoses on mine , it's not complicated at all. I know you don't mind losing some boot space, but why pay more to lose some bootspace when you don't have to?

Another factor is intercooler piping. Extra cost there aswell & potentially more lag too. A 2L running a GT3076 is already near the "oh no turbo lag" border. Add to that, you're already taking up both side vents, whereas you potentially use one for intake & the other for an oil cooler. Sure, you can squeeze a pod in somehow & relocate a oil cooler to under the boot, but then it all begins to look like spaghetti.

robk are youg etting an oil cooler? if you are let me know! group buy!

Thanks for that Jay, I'll talk to my mechanic.
Vinny, I hadn't thought too much about an oil cooler, but it's a good possibility.

Good luck with this mate! that turbo is SEXY!

i have hoses from one side of the engine bay to the other on mine, thats the easy part.

there is no harm in mocking things up now you have the parts. im thinking you might get fleeced by the mechanic as it will take a lot of labour (time) to install your proposal. i think you will find that a fair bit of fabrication work may be required as the mechanic progresses through the installation

At first I thought the main objection of MR2QIK and stuka was my decision to go with the 2x sidemount heat exchangers, but now it seems that you're more against the boot mounted barrel idea.

If I had said that I was doing 2x sidemount heat exchangers with a A2W IC in the engine bay, how would you have reacted in that case?

While I'm still on this topic, can you guys recommend a few good quality A2W coolers that would fit nicely in the engine bay somewhere?

How does the ST205 W2A charge cooler compare to these after market jobs?
As my MR2 is a daily driver I'll like to keep it looking as stock as possible, with no fancy coloured flex pipes and chrome polished intake pipes.
Maybe even keep it dirty just in case some cop wants to take a look.
