gt2871r question

[goj_cloud]

now could someone clairify that this turbo is bolt on for the s13sr. Ive heard people saying its bolt on ive bheard people say its not. so is the gt2871r bolt on to the s13 sr20det

[ILikeMy240sx]

It is not 100% bolt on. Also the "degree of bolt on-ness" (excuse my poor english) varies depending on what type of GT2871R you get. If you get the one with the T-28 style housing on it (52 trim and HKs GT-RS identical) then it will be like installing a T-28 on your engine. Even with this, you still need to clock the center section to match your T-25 and widen the oil return flange and then you have to modify your stock compressor inlet and outlet pipes to match your rubber intake and hot pipe.

If you get the regular one with the 4" (I think?) inlet then you obviously need to fab up something for the intake. and get a 90* coupler to match up the hot pipe. Also you would need to position the center cartridge as well.

I have the turbo identical to HKS GT-RS and it was a breeze to install. I just had to cut my compressor inlet pipe and re-weld it to match up to my rubber intake then get a greddy compressor outlet pipe that matched up my S13 hot pipe. That along with clocked center section made it a bolt on turbo.

Hope this helps.

P.S. get SS turbo lines as this will make your installation 100% easier.

There are some easier solutions to the GT2871R installation. Clocking the turbo you cannot avoid. As far as the pipe mods...check out the group buys on Zilviz.net. There is a guys that makes an intake pipe for the 2871 for cheap and adapting the charge pipe is a snap with the right coupler. The oil return on the bottom of the turbo is different then a s13 SR but all you have to get is a S14 return flange and it bolts right up with no modification.

The GT2871R is a great fast spooling turbo that has gotten us all the way to 11.01 in the quarter with mild cams and a conservative tune.....we plan to see 10's this year with that exact turbo.

Good luck with the build!

that's some sweet 1/4 time? What kind of tires and rear end were you running on?

[goj_cloud]

i also heard somthin about a oil restrictor bolty what do they mean

[DrifterProdigy85]

Probably talking about the stock restrictor bolt for the oil line that screws into the block. Normal 2871R is 3" Compressor Inlet. Only modification there is a 90* to go up to the stock intake pipe. Same goes with the Compressor Outlet (Hotpipe).

[ILikeMy240sx]

the newer gt2871r turbos come with the restrictor built in already. you can tell by looking down the oil hole and you will see a solid brass piece with a tiny hole on the side wall of the brass piece.

If there is no restrictor, you will see the turbo shaft.

[redtop91]

^ Good info. Haven't installed mine yet but that will come in handy. Bookmarked.

[goj_cloud]

were can i order a newer one at and how dooes the newer one differ from the old one other than the bolt

[karmakaze]

i have the 3" intake and elbow for the hot pipe that i made and used with my gt2871r for sale if anyone wants it.

it is a 3" close radius 90* high temp rubber elbow, a steel 3" 90* elbow that i cut to the appropriate length, a silicone 90* for the hotpipe, and a aluminum extension to raise the hotpipe up an inch.

30 shipped for all of it.

[leroiboy]

hey ryon what's up man. so apparently you have a new turbo. any chance you have your old one still. condition/what kind/price. thanks player

[leroiboy]

hey karmakaze. two questions. one, were you able to get that turbo identified for me or any other info on it? and 2, just to clarify, what you are selling for that turbo is ALL(in addition to re-clocking)that i need to make it work? i really wanna buy it from you if so. thanks

[redtop91]

hey ryon what's up man. so apparently you have a new turbo. any chance you have your old one still. condition/what kind/price. thanks player

Yeah I picked me up a new turbo. Ouiton you HAVE to get one of these 2871r's. They are swell LOL. I have a ceramic bladed T28 from the Skyline GTR R33. Once I put my 2871r on you'll be the first in line for it. Hit me up on my email and I'll give you the run down.

vlsd rear and 235/60-15 drag radials....1.51 60'...thats where it's at....

sweet turbos for sure!

[vanquish2]

a

i also heard somthin about a oil restrictor bolty what do they mean

if you use the factory bolt you are cool....but at the same time if you use a stainless steel line setup...the adapter that bolts into the block for the line is a small enough inside diameter to do the same job.

[vanquish2]

were can i order a newer one at and how dooes the newer one differ from the old one other than the bolt

forgot to tell you that the newer style is capable of 75hp more then the older one and all without sacrificing anymore spool time..

whether you get your turbo from me or someone else make sure to specify you want the -2 gt2871r....if they don't know what you are talking about be leary.

[karmakaze]

your talking about the gt2876rversion 2 is the .86 and version 1 is the .64

[vanquish2]

your talking about the gt2876rversion 2 is the .86 and version 1 is the .64

Nope...there are acutally 4 versions of the gt2871r...

there are 2 versions of the .86 one thats good for 400hpand the .86 thats good for 475hp

check it out

okay i dont want the 86 i wnat the 64 just tell me what the new one for the 64 is called

[vanquish2]

okay i dont want the 86 i wnat the 64 just tell me what the new one for the 64 is called

472560-15 460hp .64 or .86a/r no actuator, bolt flange on outlet743347-1 400hp .64 or .86a/r slip fit outlet743347-2 475hp .64 or .86a/r slip fit outlet771847-1 460hp .64 or .86a/r bolt flange on outlet

If you want ease of installation get the 771847-1If you want highest power potential get the 743347-2

After you have selected a turbo then chose if you want the fastest spool or most power...

.64 a/r will give you a faster spool but you sacrifice some top end power.86 a/r does just the opposite

It doesn't seem as though there is much difference but each turbo causes the engine to react quite differently

example:

743347-1 on a sr20det with no internal mods ran a 11.87@113743347-1 on a sr20det with only cams ran a 11.01@126

both were .86

^ Just to clarify you are referencing the 2871R rather than 2876R correct?

[Mouse6933]

could some one clarify the differnce between the gt2871r ,and the gtrs style gt 2871r , and i also was wondering, if you got an adapter like the one phase 2 sells, would you not have to fab the intake pipe?? thanks for the info

[redtop91]

The adapter P2M sells is for the 2 Bolt style inlet that is common among T28 style OEM turbos. The GT2871R doesn't have a 2 bolt inlet in most cases (Unless you get the RS style) so you wouldn't need it.

[goj_cloud]

the 71r

wit so there is a 2871r that looks like the rs whats the catch

[Mouse6933]

just to clarify, i wouldnt need the adapter if i got the gtrs style cuz its 2 bolt?, and if this is correct, would i still need to fab a new intake pipe or would any stock sr intake work?

[redtop91]

For the 2 bolt style the only problem you'll run into is the flange is at a different angle than the stock turbo. This is easily remedied by cutting the inlet pipe right before the turbo, rotating the piece to fit the new turbo flange and getting an exhaust shop to weld and file the piece at the new angle IIRC. Someone will surely correct me if I'm wrong.

[Mouse6933]

oh allright cuz the way they make it seem is you by that adapter , and itll bolt up, and everything will work,

[redtop91]

It will bolt up with that adapter but why pay 70 bucks when you can do the same thing for 15?
