I was wondering what the difference is between the 2 as far as boost thereshold and what RPM they hit full boost at as well.

Thanks

Even though they are the same price.....the T-88 isn't always better. It all depends what your goals are. If are all about making big numbers...then go with the T-88. However...the T-78 is a lot more fun to drive and a lot better as a street car. The T-88 is a lot more laggy. The T-78 comes online a lot quicker and therefore gives you a longer power band. And for one thing....the T-78 can make around 700hp and the T-88 can make around 800 or more.....but keep this in mind.....you will never be able to put down that much power on any street tire without spinning.

Tell that to JESUS. He uses his as a daily driver and everytime he comments on his kit it makes me wonder why I didn't go with a T88. Yes every person has different goals but its funny how most decide that they want the most power after they felt alittle of it. One thing a T78 can't do is out power a T88. The T88 on the other hand can always lower its power output to that of a T78. Its just a matter of turning down the boost....

Get the T88.

Jesus also has a raised rev limiter. Its all about area under the curve....

PHR Stage 2+ along with a PHR Stage 2 Fuel System. Its now a matter of getting them from Jarrett over a PHR. I requested that they hold everything until the PHR Race Intake Manifold is completed. No point in installing the fuel or turbo kit without the manifold.

Jesus,

What kind of fuel system will need? Will 720 injectors be enough for high boost runs? Will the duty cycle be too hard on the injectors? What is your setup and have you done many any mods to the engines internals. Sorry for so many questions, I tried to check the web site but they still have your T78 setup on there.

Thanks,

Victor

Victor, you can go to www.to4r.com and you can see the update of my car there, my car has 850cc injectors, you can be alright with 720's but I always think about the future upgrades that i could do to the car, so I went ahead and got a set of 850's, my motor is basically stock with the head ported and intake, still retains stock pistons , stock rods. Feel free to email me anytime you have questions..no problem.. :)

For me I prefer the T88, I currently have the T78 on my car now and I have rode in Jesus's T88 Supra. There is about a 300 rpm difference in terms of spool up however it all depends on your goals, If your not planning on breaking the 700RWHP barrier then I would go with the T78 and have the quicker spool, however I plan on hitting 800+ RWHP, the T88 will be going on in two weeks. : )

There are three T88's around, so you cant just compare the T88 with a T78 without being more specific:

1. T88-33D: Comes with the GReddy T88 Single Turbo Kit and is a step up from the T78. A little more lag but lots more power.

2. T88-34D: Major upgrade from T88-33D. A lot larger exhaust compressor and housing, producing a lot more power. Lag is virtually the same as 33D with a little tuning and adjustment of driving style.

3. T88H-34D: The bad ass turbo from GReddy, producing 900+ HP. Used by JUN Japan on their single turbo cars. 4" exhaust. Option Magazine did a test with the same car (RX7) on a dyno and just swapped turbos at same boost. T88H was worth something like 65rwhp at the same boost!

BTW, I have a brand new T88H for sale, and used T78-33D and T88-34D also available for anyone who wants to upgrade. For pics or info, e-mail me at [email protected]
