I plan on using a GReddy T88 for high hp purposes. I'll be dragging most of the time so lag won't be too much of a problem. I was wondering though, how terrible will the lag be? At what RPM does the turbo spool? I'll be doing full 3 inch exhaust all the way back to take down on the lag with no cat. (Alabama has 0 smog tests and cops don't ever check your emissions equipment) Mostly what I want to know is this, will the car still be streetable? I want to be able to drive it on weekends to races and sometimes just out with no races involved. Thanks for any help.

The turbine will kick in around 4000rpm. I personally like having a big turbine, when it comes to drivability because your can drive with it kicking in and killing your gas.

What do you mean by killing your gas?

If you drive and never boost your gas mileage isn't too bad. If you boost a lot...well your gas mileage goes down fast. I used to average 8 to 11 mpg.

So are you saying that driving within the lag while needing to be conservative is good for mileage? I can give a damn about mileage, it'll be weekend only. I just want to know if it'll be streetable. (Legalities don't apply, just physical abilities. IE: I don't want the lag to be so horrendous that I'll only gain 5 mph every 10 seconds until boost hits [exaggerating of course] but I don't need it to be terrible.)

T88 will be good all around. Sounds like you have alot of spending ahead of you. What do you do for a living?

if you are waiting for boost.... you're in the wrong gear

Profession? None as of yet but I'll be a lawyer soon. Right now I'm fiddling with the stock market. Thanks for the help and lol to the "Waiting for boost, wrong gear."

Please try for 1000hp https://www.nopistons.com/forums/pub...DIR#>/wink.png

What I meant to say was, it is good to have a big turbo because it won't kick in while driving normal, saving your gas.

that is a good excuse but a lame one i used to use!



proper sized turbo is so much more fun!

eh...... t88 is cool but not as fun on the street... for drag it would be acceptable but on the street something a little less laggy would be better

Man I did a T-88 on a customers car when I worked at PFS. It was just like a T-78 IMO. We all were very surprised on how well it spooled. Go for it. You will have no regrets.....

It is a lot of fun, but that is not what he asked. He asked was it going to be streetable. I say yes and gave him my reasoning.

It will be a drag car. If I ever start autoxing I'll have to take a fully different approach. This car's meant for pure hp. In response to "Go for 1,000," it's already planned. If the 2 rotor can't handle it I'll be looking into a bigger engine. Thanks for the help guys. It really helped me. (No sarcasm there, lol.)

what about the t51r turbo will it be laggy or take awhile to spool up just drop a gear right?? will is burn ur gas up to?

You are not going to make 1000hp with a 2rotor



with a greddy t-88 especally

Not expected. I'm going to see what kind of power levels I get with the 2 rotor and determine from there whether I'll need the 3 or 4 rotor.

Edit: Wanting to keep it simple for my first high hp FD. Once I've hit the power limit "wall" I'll be looking into 3s or 4s. I do, however, want to stay in the realm of the T88 sized turbo and let the 3 or 4 spool it. I'll hit 1000 someday...

understood.



good luck https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Lol, bode of confidence? Appreciated. Edit: My last name's Freeman...unless you're a Half Life fan, it looks like yours is too.

My last name is freeman...



Its funny, my GF's stepfathers last name is freeman, and all his family is from AL. Do you have any family up in maryland?

if you are really serious about 4 rotor.. here's a company for you

I'm not sure. Ed Freeman's my dad and he's from Tenn. My mom's maiden name is Dotson and she's from AL. Cosmic. Thanks for the link. (Other fellow)

I have a T88 equipped FD that I drive everyday, no issues whatsoever, the turbo lag issue is greatly exaggerated, I wouldn't worry about it. People get in my car and always comment on how fast the turbo spools. To me this turbo isn't laggy at all, tuning has alot to do with how the turbo responds as well. I mean when I step up to a GT42 turbo then I'll worry about lag, as far as the T88, I wouldn't worry about it, I'll try and contact some of my friends that have been in my car so that they can post and give you their opinions.

Appreciated.

I rode in RX794's FD plenty of times. All I can say is that the all to common talk about the greedy t-88 being too laggy of horse ****.. Rx794's FD is not laggy at all, very responcesive and fun being a passeneger in his car.. All i felt was the belt across my chest holding me in the seat from the g-forces.. So if you want to make nice HP the t-88 is deffinetly a nice investment for a 'streetable and competitive drag turbo'. I'll be getting myself a t-88 soon enough..



As far as making 1000HP it has been done on the 2rotor before just need plenty of $$ good tuning and a very nice sized turbo to make it happen. For serious power look into the 20b swap...

Agreed. Lag is a crutch used by the wussies that dont want to get rid of their stock turbos https://www.nopistons.com/forums/pub...R#>/violin.gif

When I bought my car it had a T62-1 and it now has a T70. I'd never go back!

Someone on this forum put it like this. . .if you have turbo lag you're in the wrong gear! This is very true; if you're going 30 in 4th gear lag will be horrendous. If you're going 30 in second lag will be nonexistent.

People always say lag is an issue with the t78/t88 turbos. I have the t78 on my car and i find lag very minimal. Go for it.

Thanks everyone for the help.

The T88 is an out of the box setup. I think there are better turbos on the market, and you should make something more configurable to your needs. You could find a different setup that yeilds more power and sooner spooling capabilities, but then you get into the market of having a lot of custom parts. And people who go cheaper on this route usually end up with problems; rather than the out of box solution.



The only other thing I would mention, is if you still plan to race the car on the street, you could be in trouble. If it is strickly a 1/4 TRACK car, then there is no worries. You will be tubbing it before long. But, if your car is something that you plan to race on both arena's, look at variations to a custom turbo to find that sweet spot. An exhaust housing on a turbo is easy to replace. Hell, you could keep one in your storage bin and replace for track purposes... Just don't forget to make sure it is cool before you try. https://www.nopistons.com/forums/pub...IR#>/smile.png I know of a friend who has a finger print on his housing now.



The last bit of advice, go out and ride in a few variations if possible. It is never fun spending all that money, and being disappointed - or trying to convince yourself of the excitement - with the car.

If you're gonna try variations and you're still stock and sequential, go NS. LOTS of fun.

I'm not just buying one from GReddy direct. I'll be having the turbo built for me at BNR. It'll be a little bit better and a little bit cheaper, from my understanding. https://www.nopistons.com/forums/pub...IR#>/smile.png

GT42 spools better than any T78/T88.
