Hi,
Im just wondering how good the soarer stock side mount intercooler is..
how much could i get out of a 1jz with stock side mount intercooler.. full 3 inch mandrel bent and exhaust? and what boost would i be able to run.

If it's anything like the factory JZA80 intercooler it's junk, do it right the first time and buy a decent intercooler. You'll not only make more HP, but you'll do so with less boost.
Just remember Dyno figures vary from dyno to dyno, some dyno's give extremely generous numbers while others are somewhat conservative.

There are quite a few different side-mount 1JZ coolers, actually. The biggest & best seems to be the JZX81 Chaser. I have a small thick JZX90 in the for-sale section with a link to pics. I reckon it's a nice little unit if you're happy to run stokc boost and put down stock power figures. If your are spending money on the exhaust, you really should bite the bullet and go for a big cooler. I've just got a mother 700x300x70 core mounted into my MA61 Supra.

how did you get that to fit between the front bumper mounts?>?
I thought 600 was the biggest that would fit

If you don't mind doing some cutting and welding, I think you could fit almost any size cooler into a MA61 - see Norbie's Monster Cooler. If you want to leave everything on the body untouched, I think JCMF found that 400mm was the largest. I'm also interested to see how Jaze managed to avoid cutting holes for the plumbing.
I'll have pics of the cooler in place in the next couple of days!

Mine is 550mm core size, no cutting. You would probably be able to fit a larger one if you were crafty with end tanks.
Justin, where do you live again dude? I really wanna have a squiz at your car

any chance of getting a pic of your cooler mounting, so I can see what might be done to the end tanks ?

you ma61 guys are lucky! There is only just enough room to fit the stock jzx90 front mount intercooler in my Corona.
I am sticking with it for now. And will have to get a really thick good flowing one later as i can't fit a massively wide and high one.

i was told by celicamad that my setup would make around 240rwwp which is 180rwkw. Mine is the same as yours except jzx90 FMIC instead of the side mount.
so maybe a little less if you can't get enough airflow to it?
does that answer your question?
P.S If i were you i would invest in one of celicamad's boost controllers. It has proved to be a very good addition on near stock 1j's like his.

Bassaholic: how many PSI are you running?. Im thinking about using a skyline gtr intercooler now. but 180 rwkw would make me very happy
A celicamad boost controller is alrady on the list.. where do you acquire them?
Thanks

my car is not running yet. but it will be running stock boost. which i am told is about 14psi with a 3" exhaust. that figure was justa guess though as all dynos are different.

celicamad is a member here. I think they are between $260 and $300. he has a site which explains it much better. have a search as i can't remember what it is.

heres a dumb question for ya guys, but.....
i understand how boost and turbos blah blah work, but, when you say you're running at XXX bar boost or whatever, is that the whole time the engine is running or do you have to "hit it" so to speak?? if so under what circumstances etc??
thanks

the boost pressure goes up with revs (positive feedback i think its called) at low revs, low or no pressure, more revs = more pressure = even more revs = even more pressure etc. etc.

ahhh i see. so it's constantly "on" but you'd hit a level of boost with a certain rpm??

when poeple say they're running blah boost, that's the max boost. Max boost is hit under heavy acceleration, and is usually unacheivable in 1st gear (as there is not enough load on the engine).
if you're just cruising along, your engine will typically be running in vacuum (below 0psi of boost). the harder you push on the accelerator, the more exhaust gas you produce, the faster the turbo spins, and the most boost is generated.
if you floor it, the turbo will spool up, producing more and more boost, until it hits "max boost", and at that stage the boost will not increase more (as the wastegate opens, etc etc)

rpm is a factor, but not the main one.
you can be going along at 6000rpm, and if you're just maintaining that speed there will probably be no boost - as there's very little load on the engine (depends what gear you're in of course)

ah supurb. so the same theory applies when using a boost controller of some sort? it just increases the pressure achievable in the cold side of the turbo?

yep
basically fools the wastegate into opening later, hence more boost is generated.
if anyone witha much more technical knowledge has other ideas, feel free to shoot me down and re-educate me

Mostly right, but they don't have to vent to atmosphere; in fact pretty much all factory BOV's are plumb-back.
The main function of a BOV is to prevent damage to the impeller wheel and the inlet piping from huge pressure spikes; it doesn't have much to do with keeping the turbo spinning. The turbo is going to slow down no matter what as soon as you close the throttle simply because its power source (ie high-velocity exhaust gas) has been taken away.
FWIW my intercooler split open because the BOV wasn't functioning correctly. Proof that they are important!

fark
I should look into one then - I know the factory 1jz one is not big enough to support the 14psi of boost I'm running

The factory 1JZ one is fine for 14psi (I've been running 13.5psi for almost 2 years) but they tend to start leaking from 15psi upward.

it's adequate barely. considering I'm actually running 1.2bar of boost at spikes in 3rd gear, that's closer to 16 or 17 psi

I did 45,000kms on my old 7m with NO BOV, or if you want to get technical on the factory unit, compressor bypass valve and not once did I blow an intercooler hose off, damage an intercooler or have any excess play in the turbo.
I was running 12psi towards the end of the M saga....
I now run 14.5psi on my 2JZ, still running the factory By pass valve with no problems popping pipes off and such.
Have you done a pre-intercooler boost check yet Norbie? to see how much pressure those poor little turbos are really having to push through that intercooler of yours?

Nah not yet. I refuse to believe that those turbos are capable of developing enough pressure to bend and eventually split metal though.

Just for point of interest to get 240 rwkw . you will more than just the intercooler mods .you will need 16 psi boost a much leaner than factory mixture .amd a damn good exhaust and twin dump pipes . 2 manual supra's have made over 240 rwkw on my dyno plus .
which has proven to be about 10% higher than toymods dyno ( as are 90% of dynos)
Just a note so that those that havnt read previous post are aware of what mods are required
another point

|
this is true however i have been able to in 99% of cases get the exact same boost in all gears ...EVEN first gear .That is what makes my controller a little more expensive to make. the valve system is quite unique
On the good side is the controller gets 0-100 times down A LOT lower than standard controllers

i think your probably right
i think mine is leaking . have you found info on this ?or others that have found the same problem or simply been told this may be true..... how did they know it was leaking ???

I haven't found definitive info about it (basically just been "told"). I pulled mine off last week and put a brand new BOV on and it does seem to hold boost better. There was a point on the old BOV that felt like boost was not being held in (creeping out slightly) but I don't get this effect with the new one. I don't know if it's actually better or not, just opinion from driving it with the new BOV the last 4 days.

thanx
draven thanks i actually prefer your honesty .That way people know for sure how ell my controller works .but feel free to plug me once you fit your controller

I don't mean to interrupt the thread, but has anyone used the celicamad boost controller on a 1ggte??? i would be very interested in getting one down the path if they work with 1ggte's (i know they work with any turbo engine... just wondering if they work WELL on 1g's) as i have read about them on your site before, and was very impressed, any thought's celicamad???

I've seen metal plates bolted there when people move their BOV. My new one went back into the stock hole (GFB make 1JZ adapters) so I didn't have to plug mine.

Aussie
controllers work great on 1ggte .just as good as 1jzgte . in fact i havnt yet found a car they dont work on .
i have fitted one to a stock 1ggte with the exact same rsults as the 1jzgte .
i recently loaned a valve to a mate with a 1ggte im not sure if he has fitted it yet . ill email him and find out . And get him to email you .
if a few people can get together say organise a day at a dyno shop in sydney . im happy to demo the controller on someone elses car
Danish
simply make a template to cover the oval shaped hole and get a plate cut . make a gasket or add some gasket silastic drill the hole and bolt it on
Jag7799
just getting back to your original post
if you follow the link below to my webpage i have a few dyno graphs etc on stock 1jz with similar mods .
if you check out toymods dyno day results you can see some fairly consistent results
if a chaser front mount will fit i have one i can sell for a reasonable price .they are better than soarer but nothing beats a custom big cooler
any one fitted a bosch bov ?????????
