Turbo size..

[Freshmaker]

hi guys, between these turbos, which one is bigger?

 

td04 and hks gt-ss

 

hks gt-ss and td05...

Helo Bro....

 

You comparing Apple wif PineApple?!?!?!

 

HKS GT-SS is Fast Response performance turbo capable of upto 500bhp (with appropriate setup).

 

TD04 is a standard MHI turbo..adequate upto 300ps (with appropriate setup).

bro, first of all, thanks for replying, appreciate it.

 

2ndly, im really clueless when it comes to turbine so pardon me if my questions sounded stupid.

 

i drive an mr-s and am going to turbocharge it with the hks gt-ss. just wondering if between a gt-ss and a td04 which is going to produce bigger power thats all.

 

also, the gt-ss, the gt2510, gt2530, whats the difference? beside the size that is. i presude the gt-ss is small than the 2510 and the 2530 is the biggest among these 3?

[Turbonetics]

not all cars are suitable for big turbos.

in my opinion,turbocharging is about matching the right turbo for your engine capability.

im asking about turbos in general.

 

not asking for opinions on which turbos suit which cars.

 

pls ans accordingly thank you.

You're welcomed!

 

MR-S stock engine is designed for JDM application (i.e. high compression, for running high octane).

 

As you should know, high compression + Force Induction => Engine Damage

 

Given the simple formula above, unless you are going to upgrade the engine internals, I would propose you run low Boost.

 

Ok..MR-S stock block compression ratio is 10.0 : 1.

 

Being an all aluminium block, we can assume the maximum Final Effective Compression the stock block/pistons can take is 20psi. That's already stretching the engine and we are assuming you pump 98 Octane.

 

Given we do drive to MY, I'll suggest we work with 97 Octane. (Prevent Engine Damage).

 

So working backwards, To stay within the limits, I'll recommend we stick to 18psi (Final compression).

 

To stay below 18 psi (Final Effective Compression), would mean we can only run max 12psi Force Induction. (12 psi = 8.2bar).

 

FYI, GT-SS turbo effective boost is 1.4bar so this would not be practical hence I would propose to run TD04.

 

If you install a good Boost controller (plus good engine tuning), you should be able to run 1.1bar (Scramble boost for abt 7 seconds). Ok scramble boost means, the boost controller will allow turbo spooling to run above normal boost cycle for a specified period (7 secs should not damage your engine). Why 7 secs? Cos' tats more than enuff time to accelerate 0-100km/h!

 

After 7 seconds, the controller would revert to preset Boost Cycle (recommend 0.8bar max, actually for normal driving, 0.7bar would be adequate).

 

Do note that fuelling is important. If I'm not wrong, stock MR-S injectors are 180cc (Top Feed, low impedence [8ohms if I'm not wrong]). These are defintely not enuff if you want more power (even for TD04).

 

You do not need fancyful or huge injectors, 250 to 330 cc ones would be more than enuff (cos you will definitely need a performance Fuel Pressure Regulator). The function of the Fuel Pressure Regulator are

1) Improve stability of Fuel pressure (fuel rail)

2) Increase Pressure (indirectly it improves Injector Duty Cycle)

 

Ok, think I flooding you with too much info oredi....

 

Cheers!

gd info there.....

[Freshmaker]

thanks bro.

 

i was told im gonna get the hks gt-ss, mr2 or s14 intercooler, injectors, fuel pump, and with these im only gonna boost 0.7 bar.

 

tune with hks fcon vpro (already on it)...

 

forged internals will do in the not too distant future.

 

oh and i always pump the highest grade petrol... caltex platinium for me..

 

so in order to lower my compression, i gotta change pistons?

[Eavr4]

Wow....tats loads of $$$ going in...but I still find GT-SS is still overkill.

 

Remember, you need to setup the car right to enjoy it.

 

If the car lag too much, its no longer fun to drive (MR-S is suppose to be sharp and crisp). Dun forget its short overhand front and rear PLUS, mid engined and rear driven wheels!

 

Too many horses, you must really know how to control. My suggestion is to setup a wide power-band instead of a steep and peak power (Typical of big turbo). Tuning plays a huge part.

 

Oh! If you are going to invest on "bodykit". Do consider WIDE BODY ... this will give you huge advantage to "alter" the geometry of the car setup. Its not only for asthetics but would really "balance" up the car too. Run bigger and wider thread width in the rear as opposed to front (meaning the distance between the left and right wheels is further apart at the rear). Exact increase would require further research but its a suggestion you can consider. Improves handling and allow you to have more progressive control esp power delivery in corners.

precisely bro.

 

thats why im asking around and looking for a resonably good turbo with all round smooth power range, instead of hardcore brute power which tends to lag.

 

all these and of cos, not comprimising too much of the handling.

 

i have no idea the gtss is such a "high end" turbine.

 

here's to illustrate better..

 

 

by the way, widebody is kinda out of the question now... it'll cost me 10 grand and i'd got to change my rims as well.

 

im currently running 16 inch front and 17 inch rear, 205 tire wideth front and 235 rear.

hi guys, between these turbos, which one is bigger?

 

td04 and hks gt-ss

 

hks gt-ss and td05...

 

 

 

Ive got a complete turbo set with chip taken out from airtrex 2.0 anyone interested letting go cheep sms 98775522

[Turbowong]

anyone can help? got a prob. i wanna lower my engine compression a lil. is it ok if i custom make a thicker head gasket? cos my workshop told me my pistons are quite close together. if i use thicker gasket might leak. but i got feeling they dun wanna do. cos troublesome. hope someone help. : )

[Freshmaker]

actually anybody know what is the way to effectively lower the compression of a car???

[Elfenstar]

Proper way is to change internals. Cheaper way is to use a thicker head gasket.

[Furrynadz]

i see a new entree for the tree hugger club

[Xeryh]

Thats some amazing info there, thanks for contributing.

[Nazaki]

The td04 suits ur setup the most.

You can take better advantage of the higher torque and smooth power flow.

 

 

Anyway, which workshop are u gonna do at?

 

Check out those reputated workshops (Garage R etc) and ask for advice as well. If they charge a little higher, its worth it to do it with them than some other workshop which might just mess up ur car.
