3 things I think are necessary for your fist

[aruth55]

I believe if you’re going to be pushing and tuning this car hard, these mods are necessary to maximize your fun, and the motors safety by keeping it cool!
1. Radiator upgrade of some sort, I recommend mishimoto personally, best flowing core and largest coolant capacity. I have experienced the horrors of having the stock radiator, it isn’t fun. And if you want to run an e30 tune and your a/c at idle with stock radiator, you will overheat (at least I did once before I learned my lesson with that and people I have spoken to have).
2. Intercooler of some sort, I recommend Depo or whoosh, both are a great value and get the job done for stock turbo and hybrid turbo applications! Big turbo I cannot attest to as I have never had one. But I feel the stock intercooler is pretty much maxed from factory.
3. A tune by Adam at Tune +, simply the best in the game.
Something I want to try next is an oil cooler, I think the car could benefit from that as well, mishimoto is the one I’d try, since I know it fits with the radiator.
Let me know what you think!

All of this rings true except one can get the Mountune its cheaper in price and its a quality built radiator and more than does the job. I have a Mountune on my car and I am in SoCal which gets pretty damn hot.
I also do not think the Mishimoto is the best flowing core. The Mountune is a triple pass cross flow made by CSF its a very high quality radiator and would not hesitate to say its better made than the Mishimoto and yes I have experience and knowledge of Mishimoto with other vehicles.

I think its a solid list to upgrade all 3 said parts. Would have to agree upgraded radiator and IC are solid choices. Haven't done a tune plus tune myself and tempted to go that route.

I have mixed feelings around Mishimoto. quality control and customer service can be questionable. a lot of ppl complain about the fitment of some of their parts in the evo community, particularly their oil cooler setup. Wish we had Koyo or CSF radiators. Have had good luck with those in other cars in the past. Used to be that a Koyo was my default first mod.

Mountune is a CSF radiator. Ask me how I know.

 

[ronmcdon]

Good to know. Weird how CSF doesn't just sell their radiators directly for our application.

Would be funny if Pro Alloy radiators were just rebadged Mishimotos.

I believe when you purchased the mountune it must of been cheaper at the time, listed at $559 but now the Mishimoto is “on sale” for $557, a $2 difference so now it’s really up to personal choice. I do remember though when the mishimoto was listed for around $750 or so. I suppose the reason I went with the mishimoto is because it is larger and includes the fan shroud for the stock fan, which I thought was a cool upgrade and allowed for better flow. I also read due to the fins of the mishimoto radiator being slightly farther apart, it allowed for better flow. That could be completely false though. I would think though, honestly, when it comes down to it, they perform about the same and show the same temperatures. I have heard the complaints about mishimoto as well, but I also believe they get more hate than they should. I have their intake as well as the radiator, and both had extremely good fitment. I also have had friends in the Subaru community use mishimoto products with no issues. That being said, I also don’t think the people making complaints are lying. I have heard great things about koyo radiators from my buddies with the subarus also, I wish we had those available. It seems there’s almost a monopoly on the radiator market for these cars from mountune and mishimoto and they’re able to jack up prices to the moon, compared to their radiators for other cars. If you’re thinking about tuning, Adam truly is the way to go. I have had stratified and dizzy e30 tunes, and saw knock regularly on them, not WOT, but still. I know it’s “normal” for these cars, but on Adam’s tunes (including my base tune) I never saw or see knock. There’s also a good video, showing a bone stock fiesta ST on Adam’s e30 tune giving the gap to a FBO dizzy e30 tuned fiesta. I already had tune + at the time, but if I hadn’t, that sure would’ve swayed me, lol. There’s so many other reasons as well I recommend Adam. He truly is the best, and I’ve yet to see otherwise.

Radiators are really expensive for our application. Have not recalled paying a lot over $300 for other cars ive owned with a csf or koyo.

idk who manufactures Whoosh radiators but that is more affordable. Think someone mentioned CSF but can't recall for sure.

The thing I don’t like about the whoosh is that it’s only a two pass core. I looked into those oil coolers today, almost pulled the trigger, but saw honestly, a bigger radiator does the job, and pairing one with an oil cooler really only sees 10-20 degree lower temps, from people who track the car heavily, so almost seems not worth it, having higher chances of leaks and paying the money.

Based on my experiences: I know I certainly wouldn't recommend Mishimoto products on our platform.

I believe the Whoosh is a triple pass now, first batch was dual.

Ahh I was not aware, good for them, I love Ron’s products. Hey off topic, but anybody ever get vibration on their shift knob like the smallest bit going into 4th? I have whoosh base bushings installed and a cobb rmm, could that be why?

I've never had an issue with my stock radiator overheating in Texas traffic.

E30 burns cooler, so I don't understand your logic regarding it and overheating.

Maybe you’re one of the lucky ones, but it’s a pretty common issue in stock cooling system. Also that may be true, but increased timing results in higher temps.

Shouldn't have much timing idling with the A/C on.

I mean a lot of cars that are modded and tuned hard have a/c deleted as you know. It is a pretty common problem with this car though on the stock cooling system if you read around, not sure what the issue was with my oem radiator but since changing it I’ve had no issues.

I trust my E30 tune more than my 93 tune, especially once it gets hot outside. I'll be switching over back to E30 in the next few weeks once our lows start trending in the 60's and the highs in the 80's. The only reason why I've kept my stock IC so long is because I run E30 more than I run 93.

Honestly maybe you’re one of the lucky ones, but I know personally my ic and radiator never held up how they should’ve. That’s probably just ford engineering and quality, lol.

SO, from Texas and running a Stage 2 tune with the stock radiator and IC? Please tell me more...I am in the Houston area and really want to avoid replacing the radiator just for a tune.

I'm presuming he has a "stage 1" tune. That phrase is a bit misleading.
Cobb sells 3 stages, based on hardware. CAI and intercooler is 2, and DP and exhaust is 3. However, any tuner will tell you stage 3 doesn't do much if anything for a stock turbo. Sounds cooler, but it's not faster.
Others consider a big turbo "stage 3," but none of them mention radiators.
I don't need an aftermarket radiator where I live, but if I was in Tucson, it might be necessary for anything more than a stock tune; it's usually hot, and you need reliable AC.
