damn you do learn something new everyday

ummmmm..... i thought all turbo has to have a intercooler for the intercooler to suck in air to cool down the turbo or else what other way will the turbo cool down by?
Anyways thats what i thought there might be another way to cool the turbo but iv never heard of it? If there is i would love to find out please.

Nahh. Im sure there are non intercooled cars man. And as zhong said, turbos cooled with the oil like the engine.

Turbo cars don't "need" intercoolers, but you'd be crazy to run one without it. In fact, turbos are generally cooled by coolant/oil - hence oil/water lines, these "cool" the turbo, where as an intercooler "cools" the intake temps.. If the compressed air is used as compressed air, the boost will not be efficient nor will be give you reliability. FMIC kits go for about $400 only anyway... If I didn't have things to pay off at the moment, I would've purchased an ebay kit and replace the flimsy bits and do a full write up, as I strongly believe in "how it's installed" not "what is installed".. I have many friends who do run ebay kits, I mean for the $$ it sure does give you the extra kick you'd want.. It's all in the turbo and the tune...

My 0.02c anyway.

Peace.

Agreed. Even so, you can buy second hand garrets for cheap, and just run intercooler, BOV, pipes, maybe not wastegate china brand..

A car can run without an intercooler as not as its not running above Approx. 5psi. I hovever do not know of any Turbocharged production car that did not come with one though.

A guy on supraforums bought an eBay it for cheap back when na/t was the big thing on 2j's. It ended up costing more getting it fitted and tuned that a pretty much bolt on kit from a reknown company. He drove this car for a few months on 12psi (This is ow for a 2j) and he still managed to blow the turbo.

Didnt really get second part man, but for first part, there where many non intercooled cars. From rolls royces to Merkurs. Murker XR4Ti, which was running something like 12 psi from factory. Rolls Royce had v8 Turbo non intercooled engines..

So is anyone going to do it?

[sambalam]

no, not even a little

[VeYzZii]

I will, when i get funds. 80 percent sure ill do it... Maybe not with a chinese turbo, but with chinese piping + intercooler + bov..

[zhong]

If you do get the ebay kit, make sure you get the one that comes with complete.. The only items I would think about using are:

Roughly $800 delivered as a kit: Rough prices seperately

- FMIC + piping kit (make sure it's the t-bolt clamp style clamps) - ~$450 del
- Oil Re-location kit - ~$50 del
- Turbo line kit - ~$50 del
- BOV - ~$60 del
- Manifold (Cast) - ~$300 del
- Intake pipe - ~$25 del
- FPR - ~$40 del
- Wastegate (Would use but won't expect to last.. But I know many many people who use ebay gates with slight mod and works up until this day w/o problems) - ~$50 del

Another bunch of greenies:

- E-manage/AEM - ~$700ish
- Injectors - ~$250ish (>450CC+)
- Fuel pump - ~$50-$200ish (OEM Nissan pump vs Bosch/Walboro)
- Snail - ~$100-$900ish (OEM Nissan vs Branded)

So really, the only thing I won't trust complete from the kit, is the turbo.. If your doing it in your own garage, I'd give the ebay turbo a go otherwise just get a smally like a HKS or even try one of the skyline turbos (cheap as chups), proabbly need to get another turbo line kit as nissan turbos are cooled by both oil and water. Not bad for roughly $2,500AUD, especially if your going to do it yourself.

DO IT!

LOL, Patience..
I need to know if just bolting the F$%^& on will be fine, cause i have people coming up to me and telling me that the compression from turbo will blow the motor.. Cause s2 run big compression stock..?

[zhong]

Yeah, it's 11.0:1 compared to most turbo cars around 9-10.. But that's why you get a tuner to tune it to safe levels, as long as you don't get too lean (greedy). A thicker headgasket will lower the compression if your uber worried and want to run insane boost.. But my bet is that if your running low 6-10psi, it's fine the way it is depending on your AFRs. After bolting it on etc, especially with the new injectors etc it probably would run really sh*t.. So a tow to the tuner is probably the best..

I also have people coming up to me saying that if you don't use a BOV, your turbo will blow up. And if you don't have a fully hectic 3" exhaust with a high-flow cat, your car is going to be restricted.

[VeYzZii]

Ill probably pass the 'greenies'. I dont wanna run to much boost. Im still on P's and want it to sleep.. Will a tune be able to lower compression?? Ill have a BOV, and uncles own Liverpool exhaust, the exhaust will not be a problem. And whats AFR?

[zhong]

A tune will not lower compression, because it's a mechanical thing. However, a tune can make your setup more safe for a certain boost level etc. AFR = Air Fuel Ratio, what the engine needs to produce combustion in the chambers the exact amount of air/fuel is required, the faster the rate of combustion the greater the air/fuel that is needed etc etc.. If you don't really know the basics of the mechanics of an engine, let alone a turbo engine you should get a mech to do it..

Otherwise, go the supercharger route, it's totally DIY and not much tuning required (less power).. Although they do range from $2-4k second hand as complete kits.
