Charge cooler

[Born2Run]

I know this topic has been discussed many times but this has a twist. I have a rev 1 tubby with usual upgrades (still need exhaust and cooler upgrade). I am in the process of returning to South Africa where I will spend 6 months of the year and will be taking the tubby with me. The area I am moving to is hot (very hot - 35 to 40 deg during summer) so an intercooler isnt really an option. I know Rogue sell the pace and Dino has his prototype coming into production but I am looking at a cheap option, namely the GT4 conversion (I have 6 months of spare time to kill). Question! Will the ST205 cc fit a rev 1 and how hard is it to do. Does anyone have details of the conversion.
Any help appreciated

You'd be able to match the turbo end of the ST205CC to the CT26, but the main problem is that on the throttle body side, the outlet of the ST205CC is sized to suit the ST205CC "sock", but not the ST185CS "sock", so it means that you can't just use stock Toyota bits to get the conversion done. The ST205CC sock won't fit the Rev1/2 throttle body without being hacked about (this is what Mark Edwards has done).

What you *could* do though is get someone to make you an adapter plate that matches the Rev1, and has short stub tube on it so that you can use a short section of hose between the ST205CC and this adapter that you'd get made up.

Then, you'd need to bend at least one of the ST205CC water tubes so that it clears the coolant housing on the side of the engne.

It CAN be done, but needs a bit of thinking and bespoke fabrication.

HTH.

Cheers for that Dino. Big help and within my capabilities. Got 6 months to experiment anyway.

I expect to be shot down with this post but what the hell. If you dont ask you dont learn. I notice that most people who do the ST205 cc conversion use a cinquecento rad as a pre rad and mount it in front of the stock rad. Is it possible to either convert the existing stock ic to a pre rad and increase airflow using a spal fan or failing the conversion mount a normal rad (from a donor with suitable size rad) into the ic space and again run a spal fan to increase airflow. I know airflow here isnt anywhere as good as front mount but maybe a single or possibly push and pull spal fans would overcome this.

JJ (on here) did this ages ago mate - seemed to work well for him

Thanks Jay. Big help. Saw a post about someone in the states who had done it so dont feel too stupid now. I just noticed that most people who had gone with the front mounted cinq rad had done away with their a/c in order to run the water pipes where a/c pipes were. As the summer temps average 35 to 40 degrees where I am going, I really dont want to lose a/c.

[Quigonjay]

pretty sure you can do it AND keep the air con - dino will be able to advise on that count

Mate, I too tried the same setup as JJ, but when I looked at the logged data afterwards, it wasn't good at all. Maybe wouldn't be *too* bad if you only ran 10-12psi, but above this and the temps were useless.

I then fitted the Cinquento rad at the front, still keeping the AC, and the temps dropped DRAMATICALLY. IMHO, it's not worth trying to fit the pre-rad anywhere else but the front.

The Cinquecento rad was discovered by Mark Edwards, as it was just the right size to fit up front and still keep the AC condenser. However, having used the Cinquecento rad myself, and seeing how flimsy it is and how time consuming a job it is to take the front of the car off to do anything with the rad, you REALLY should consider getting a more robust rad. I'm not just saying this because I'll be selling an ST205CC install package (consisting of a decent, bespoke front rad and pump). Personally, I would want to just install the whole lot and never have to worry again!

[Born2Run]

Thanks guys. Dino, did you have to lose the aircon when you ran the cinq rad. This is my biggest worry. I cant imagine driving in 35 deg temps with no aircon. It looks like I will have to go the cinq route as I currently boost to 1 bar. I am not looking for any huge power gains. More worried about the temp side of things.

No mate, I kept the AC (I know, I'm a woos too! ).

The cinquecento rad fits nicely in the space in front of the AC condenser, but the problem is you have to make your own mounts, and you need to adapt down from the size of the inlets/outlets, which took a fair few adapters on my own car. Each such connection is a potential leak, and you HAVE to test it all properly before you put the front nosecone back on, otherwise it'll all have to come off again!

Before you embark on this route though, mate, I'd recommend that you price all the bits up (ie Cinquecento rad, joins, mounts, pump, lines, etc). I think you'll find that it won't be that much cheaper than the kits I'll be selling, and the added bonuses are that they're be straight bolt on, the rad will be much more robust, and the rad offers slightly better cooling too. That's the end of my persuasive sales talk though.

Yay, credit for it!

[nutter]

i didn't have to remove my aircon when i fitted my pace chargecooler.

[Born2Run]

Thanks guys. Thats given me something to think about. I am not leaving until October so hopefully Dino will have his cc kit in production and I can get a better idea of which route to take.

I second that ! To be honest, its good for a quick blast now and then, but sustained boosting / track driving or generally being a hooligan on the road, it cant beat a front mounted which I've always advised people as the route to go down.

My theory of using the stock intercooler was later to use it in conjunction with a front mount which would yield the cooling required, but the side mount would still continue cooling sat in traffic when there was no air flow through the front. Sure, other alternatives are to run the stock cooling fans from a seperate remote switch, but I thought I'd give it a go nonetheless !

Thumbs up for mark edwards on his Cinq rad find everything else I tried wasn't having it !

[Born2Run]

Cheers JJ. Was going to pm you to ask for your input. Guess its front mounted then. The area I am moving to is more of a sustained run than quick blast type area. No traffic to sit in. Just long open roads with very little traffic. Easy to guess how I am going to be passing the time.

I think that's why he HAS to go flat out everywhere!

[Born2Run]

He he. You got it. Dont think any carjackers are going to catch me. Mind you, many years ago when the BMW 850 first came out, some rich dude imported 1. Take into account imports cost an extra 110%. It lasted all of an hour before being hijacked. So, the more power I have, the longer I last

If you want a ST205 Charge cooler system try www.japanimportcar.com a few weeks ago they had a system which they said I could have for £375 delivered inc vat. This included the following parts:

ST 205 Charge cooler,
Pump,
Front Radiator,
Pipes,
Expansion Bottle,
Throttle body,
etc.

You would still need a different radiator I think and i am not sure about the Throttle body, sure someone will answer this: Can you put the Throttle body from a st205 on a rev1/2?

I did not buy the kit in the end had other things i needed to spend the money on first

I was going to say, has anyone tried to fit the ST205 pre-rad? From memory, it's not too big a unit, so *may* fit, although I'd imagine you'd be able to get better cooling with either a Cinque or bespoke rad.

Also, with regards to the ST205CC pump, I've seen a couple of failures now, of pumps that were wired to be on all the time when ignition was on. This is not how they are intended on being run as standard, so it may be that they're pushed over the edge? Also, they're a heft item, and you could save a fair bit of weight by going for a better pump.

and i am not sure about the Throttle body, sure someone will answer this: Can you put the Throttle body from a st205 on a rev1/2?

Hmmm, interesting idea, as this would mean you could not only run the ST205CC sock, but also have a larger throttle body, but I'm wondering whether:
1) it'll fit
2) the TPS sensor will be the same
