S13 DET Turbo kits??
Ok, I want to upgrade my S13 DET turbo, what I want is a quick spool up, and 300+hp, I was thinking about the HKS GT25, but I'm not sure I want to spend that much on that, maybe the bbT28.

I really want something that will bolt right up to manifold&plumbing, just to make things simple, and cheaper.

I have heard you can send your T25 in for big mods and get great results.

What do you all think??

Thanks,
Bruce

The modded T25's may not spool up as fast as you'd like. Garret makes a T25R for about $1000 that is ball bearing and has a high flow capacity. I haven't heard of anyone using it but it looks like a nice competitor to the HKS turbos.

cheaptubo.com has it I think

Quote from a fellow 240 owner Thanks Aubrey!

Need More Power?Time For a Turbo Upgrade!

After reading This FAQ please read the following....

You could spend weeks looking at catalog's, websites, and speaking on the phone with people about the 1001 different turbo's that could make good power on your car. I am going to give two options, one that will make 325whp 335wtq, and another that will make 400whp 350wtq.

To make things easier I will go ahead and price out ample fuel for either system:

740cc Tomei Injectors: $530 http://www.phase2motortrend.com/tom74sr20det.html
Z32 MAF--$120 www.ebay.com
JWT ECU--$595-100 ka core $495

Now of course you could get MSD injectors and a custom fuel rail but the injectors i suggested seem to be the most simple option as they drop directly in the factory fuel rail. Also, you could just as eaisly use a Cobra MAF. The S-AFC could be used instead of JWT but you do not have control over your ignintion timing and will be hard pressed to get the same results. Do it right the first time. JWT with a S-AFC is a great idea or if your pockets are a little deeper go with a stand alone, just keep in mind that with a stand alone you need to know what the hell you are doing. For people who like the plug and play option JWT is the way to go.

On to the turbo's:

-----------------------------------------------------
325whp 335wtq

Forced Performance's Big28 $795Forced Performance's site
They need YOUR T25, you cannot ask them to use a DSM core for the additional charge bc it will NOT bolt up. The price on our upgrade is 795 NOT 750 like they advertise for the DSM's.

The beauty of this turbo is that it bolts on. Everything, and i mean everything, bolts up just as stock. You send them your turbo, you get it back, and you bolt it on. Absolutely NO modifications to any pipes or lines is necessary.

Streetablility: Boost comes on strong at around 3200rpms (not the 3100 the say) and pulls hard till redline. This turbo is efficient up to 22psi. This turbo is very fun around town, very little lag so the power is almost instantaneous.

Times: With that kind of power your trap speeds will be between 116-121mph. Thats high enough for a mid to high 11 with some slicks and a 1.6 60ft.

TOTAL= $795+Fuel= $1940

--------------------------------------------------------

400whp 350wtq:

T3/T04E $650
360 degree Heavy duty Thrust Bearing
Turbine: .64 AR Stage III wheel
Compressor: 50 Trim T04E

Opinions based on Compressor Charts:
.46 is too small.
.82 lags too much and isnt worth it
57 trim gets owned by 50 trim (50 trim is more efficient)

JGS manifold: $360 Phase 2 JGS Manifold
Custom Hot Pipe, Intake pipe, and down pipe elbow--$300 your local muffler shop that does Mandrel Bends
Tial 40mm Wastegate--$325 http://www.jgstools.com/turbo/
Steel Braided Water/Oil Lines--$75 http://www.jgstools.com/turbo/

Streetability:
Being that its a little larger than the Big28, boost is going to come on a little later. Boost starts to fly up around 3500rpms and good power is in by 4000. Larger AR's in the turbine will push these numbers a higher. This is, in my opinion, the best setup for a high HP street car on stock SR internals. On some race gas and 23psi you should see a little over 400whp and a little higher than 350wtq.

Times: Traps speeds will be between 124-128mph. Thats high enough for a low to mid 11 sec car with some slicks and a 1.6 60ft.

TOTAL= $1710+Fuel= $2855

--------------------------------------------------------

Like i stated above, there are so many turbo options out there that it is very hard to decide what it best for you. These are the two options that will be the most cost effective. Ball bearing turbos and other japanese turbo "kits" will be much more expensive but will not provide that much more power. Boost will be a little more responsive and will not be as likely to fall off between gears. One might be quick to say that they would last longer being that they are ball bearing but that is not necessarily true. If you take care what you worked hard to purchase, it will last (read: Let the SOB cool down after hard runs!!)

My 2 cents.
