radiators which one

got a na to tt conversion done jspec auto

looking to change na rad to tt rad or asi ,

which would be more suitable

prob gonna fit seperate transmission cooler to due to increased bhp

open to ideas etc...

im not too sure what the difference between the na and tt rads is. but i know there is one. I had a alu rad (flidine) in my car but it gave up the ghost all along the top. Put a stock one back in and its been great. There is a lot of debate between tightly packed fins and denser copper construction against ally ones which tend to be less dense. In my opinion the stock copper one won out. Half the price and i remember from my science GCSE that copper is a better conductor than most things

thats helped so the stock should be stronger and probb better at heat loss..

Well like i say. Some people say "uprated" ally ones are better. some say stock ones are great as they are. I pm'd someone on here who i trusted to give me an honest answer who wasnt just trying to shift a ally rad that was double the price of the stock one. Then the garrage i was having the work done at came back to me and said they looked at some of the ally ones the supplier had and the quality of the manufacture compared to the stock unit was crap. that confirmed it for me.

Im prety sure the garrage would have rather sold me a nice expensive rad if they thaught they could

the plot thickens?? some good points there, its like you say ive had the same some say alu rads others say stock..

no solid choice i guess

wen ive looked at other sups at meets most seem to have alu rads maybe cas there shiny??

i think thats part of the reason yeah. Email Chris Wilson. He will point you in the right direction im sure

thanks for help i'll see what he says

The n/a rad is thinner. Although I used it with my TT engine and never had any over heating issues with our rubbish weather.

it is thinner as im finding out but just gonna upgrade to suit eng upgrades

Paul at whifbitz is doing a good deal on the Koyo rads at the min, its in his special offer thread.

ok i'll av a look

I have an ASI rad on my BPU tt 6 spd. For £150 I don't think you can go wrong. Never had a problem with fitment or quality. No overheating even on the hottest summer days during spirited driving with an FMIC.

The later model TT's come with the thinner NA rad so there's no need to replace your one unless it's faulty.

Personally I'd go for a decent stock one over an alu one. That is unless there's now a model that can be used with the stock fittings and fan shroud...

I assume you've gone from an NA auto? Isn't there a difference between manual rads and auto rads?

Just remembered the rad shroud will need replacing too, the NA rad shroud is different (to accomodate the slimmer rad)

Only that they have the auto box cooler in them. Not sure if the NA ones have it, but would guess so...

hopefully my big ass tt rad should deal with the problem in hand, ran it on my single and never once let me down, water temp always stayed at a constant, neva run up anywhere near the red section.

Basically they are all much of the same thing. If it works, fits and lasts who cares. The stock rad is a good unit but to say because Toyota built it and used it means it can't be beaten is delusional. Cars are built on tight budgets, corners are cut and components spec'd to particular requirements. It was fit for purpose that's all.

It's your choice but why pay more for something that does the same job at half the price?

na na na na na! i completly disagree. the supra is strange, the guys designing it knew that it was going to be modified. the stock tt is what 300hp yet the engine can handle up to 600-700hp while still stock, look at jamies car. Also i was told that the gearbox can easily handle 700hp as well.

The reason I would be reluctant is due to the fitment issues with the stock fan shrouds. This will do a lot to damage cooling capability it they can't be fitted. I'd just get a known good 2nd hand stock one, it'll be a lot cheaper than buying a new alu one and will fit perfectly.

My ASI rad fitted fine. No fiddling. Direct swap, fan shroud fitted fine.

have gone for the tt rad stock unit its made for the car..

go with the standard flow

thanks for help and advice

it always best to gain some knowledge first on these things. i be honest i have been so happy with a wide range of the stock parts on the sups. for example the uk brakes etc.

I totally agree. The car is over engineered. My point is that the cars engineering is probably 20+ years old now in total. The stock rad is good but not the best. Why pay £300 when you can by a unit that is a direct swap and in my case has never caused me an issue for half the price.

I think most people choose stock for comparability and lack of hassle over quality and performance.
