im dropping to the dhra street class and wondered if anyone knew anything about the gt4202r garrett turbo. im hoping it will be a stout single charger for my setup, and make me competitive in this class

 

Not sure about the Garrett 'charger - but do you have the two 3/8" bolts bisecting the DP at 90*?

 

The 4202 is quickly becoming all the rage with the big power Duramax guys, several trucks running it have spun 700+ hp. with fuel only. Of the top of my head I think it flows something like 1488 cfm?

 

yea ill have them once i have the charger and have a downpipe. i had them last year because i ran the super street class but my exhaust exited thru the hood so i gotta make some changes

 

thats good to know because im hoping to make some big power with it, i think i got enough fuel

 

had one last year. and will be running it again this year. just remember they are throw away turbos ,you can't rebuild them most figure they are only good for a full season of pullin.

 

what do you consider a full season of pulling? im from eastern pa so i might get 20-30 hooks on it in a year if im not too busy with the farm.

 

What's the purpose of the 3/8" bolts - shrapnel control?

 

yeah, it should slow alot of the stuff down when a turbo goes boom

 

thats a full season , it should last ya that long depending on how far out of the map you get. I hold about 70psi non wastegated with mine just make sure you get a 1.01AR version most come with a 1.15 or 1.28. I ran 1.01 and am going to a 1.28 this year . I tried it last year but didn't like it but i am tryin it again since I cracked my 1.01 last year.

 

what didnt ya like about the 1.28? i was told to go with something like that to keep the drive pressure down

 

that is true , but it is a pig to spool up with it ,I would be a bit concerned about keeping it lit with your stick . it doesn't come on till 2200 for me with a 1.01. but I did allways think it would be crazy behind a stick w/rpm and it has a T4.5 flange not a T4 so you will need a big foot flange and then I just elongated each of the four holes(on the exhuast housing) about a 1/8inch and it fit prefect.

 

I think I would buy a lighting from scheids it is a 42 hybred and is rebuildable and it runs real close to the GT

 

alright well thanks for all the info ill look into it more before i make a decision. thanks again

 

I think the 4202R has a 74mm (?) compressor inducer. It'll need to be bushed down for the 2.8 class if I'm thinking correctly. Good luck with it, andy
