Stepping up to a GT42
 

My older T88 is maxed and in the need of an oil seal and for the HP that I want to make I decided to step up to a GT42 (non ball bearing) rather than rebuild the T88. I've searched and not that many forum members are actually running this setup. Does anyone have any quarter mile info with a GT42 on an FD?

Thanks,

Anthony

What's up anthony. great video. i also run the greddy t-88. i was also looking to upgrade. why not the gt 42r? do you know what is the difference in recponse between the two turbos? is it worth it price difference? i don't know the price difference.

the price difference is fairly significant i beleieve you can a journal bearing 42 for about 1100-1200 but the 42r is around the 2k area i got mine new 1900 on sale alot of places vary in price. by the way anthony beautiful car!

Good thing you don't have blond hair, nobody could tell us apart :D
You may want to consider a Borg Warner S400. Dee can probably hook you with that.

I'm on a budget with the car and the price was almost doubled so I opted for the Gt42. The G42 is like $1000 and the ball bearing version is like 1900. Not sure on the spooling difference....

Thanks!

you already know my feelings on this, whatever you go with i just hope you have it running by bear mountain.. give me a call if you need a hand with anything.

lol, i'm getting the gt42 for a great deal, almost free I guess you could say. Dee did talk to me alot about turbo choices and he likes the borg warner stuff too.

How's your turbo on the launch?

He is running a plain bearing GT42. Made pretty good numbers I think. 562 @ 22psi.

As you know, Im still working that out! lol....But I'll get it. Just take a bit more time.

with a big turbo you just need a little 2 step action and you shouldn't have a problem off the line :)

Hey Ernie!
Where did you get your version of the GT-42 with the invisble compressor wheel! :lol:

I kinda meant do you think its the turbo or the longer 1st gear? There have to be others running this turbo on the 1/4 mile to get more info on the 60fts you can get out of them?

Anthony

whats up anthony. just wondering if you need to modify your manifold or would it bolt up the way u want?

It will not fit with the current manifold but my friend made an extension that bolts in between the turbo and the greddy manifold to make it fit perfectly. I just have to redo the intercooler piping and the downpipe. I'll post some pics of the adapter. Also, I am going to send out the adapter and the manifold to a local machine shop and have them fabricate a new manifold for FD's (when I have some time).

Anthony

that cool. i was thinking of having a friend weld something up for me when i get the turbo. cant wait to the pics thou

If J-Rat can do a 10.7 on a T60-1, I am sure you can do a 9 second run on a GT42.

I doubt its either. Just need more time getting things worked out. Takes a long time just get it all to come togeather. Getting the power is the easy part. Many are running much larger turbo's than I do and have issue's with putting the power down. Just a matter of trial and error.

Don't want any large birds flying into it! :D

I cant complain about the turbo. I havnt run any real boost through it at the track yet.

Rat was also running 25+psi and a ton of methanol. That makes a difference.

Az,

Nice times on 14psi, I assume that's with the GT42? Also, did you run the car with the 562HP down the track yet?

Thanks,

Anthony

Anthony, I'm interested to know what you think once you get a new turbo on there. I'm also looking to upgrade.

Thanks, zinx

Not sure on the spooling difference....

ive got one on the way. non bb. ive herd that there is not much differnts in them at all. this is from a guy running mid 8s in his 13b mazda 323, he's had them both.

I don't know why he ran so much boost... that thing blew hot air after like 22ish psi....

But yeah.. you should at least do a 20psi run =)
