Intercooler necessary??

[SIX_SEVEN_ONE]

Wassup everyone,

As some of you may know I'm putting a 1j into a Toyota Hilux.
Anyways a friend of mine suggested that it'll be ok to run without a FMIC as long as I got a meth kit to help with cooling.
Well I do have a stage 2 Snow Performance kit but wanted other peoples opinion on this.

Will I be ok without a FMIC?? My kit is a progressive one so I can get it to start spraying at low boost.
Will be running the stock twins for now but have a Holset 35 or 45 I forgot which one that I plan to put in later.

Any input would be appreciated... :boink:

In the old days I ran lots of Turbo engines without Intercoolers, only thing you need to keep in mind is you'll be boost/sparkadvance limited on pump fuel.

Can you explain what you mean by this?? Thanks!!

Hot air is going to limit you.

Better off running some sort of an intercooler. Doesn't have to be a front mount air to air. Can get a water cooled intercooler.

Charge temps lead to detonation, you can only run some much boost and so much spark before it breaks the engine, keep it below this point and it's fine but in this day and age there's no reason to not run some sort of intercooling.

Back in the 80's I was running 30psi non intercooled but I started with 6.5:1 compression, TOTAL slug off boost.

Even with meth/water injection I'll be limited??

Keep in mind the 1JZ had a larger intercooler than the 7M. Makes more power out of a smaller motor...

Personally I wouldn't use meth for that level of protection. Meth is good when you have safeguards (i.e. you're running it for a high boost setting and if you don't have flow it drops boost down to safe levels), even at stock boost it was deemed necessary by Toyota to have an intercooler and a large one at that.

So far as I know, you can't retard timing on the 1JZ like you can the 7M so it's just not a good idea IMHO.

ya this is exactly why i had to ask. Now heres another question? Will a cheap ebay intercooler be ok?? I was looking at Treadstone cause thats what I used on my Turboed V6 Tib but considering I will have a meth/water will a cheap $100 be fine??

Thanks!!
