IF! u can choose between a GT25R, and GT28R???

Post by **Loofee95SE** » Thu Apr 21, 2005 3:20 pm

Its that simple, which turbo will u choose??

I'm looking for something that will improve my midrange ( compare it to the .80 A/R SR T25 turbo that sucks nopower under 4k unit that i have on now). I'm not looking for Bragging right, just a fun-to-drive-carthe support mod that I have now + coming soon are " 1. 4x 550cc FC injectors, 2. Z32 maf, 3. Apex-i AFC II ( i have a 1st gen S-AFC on mine now)

and what it would need to fit those snails on my stock CA Mani ( which will be extrude hone this time before I reinstall) ( I search but seems like they erase the posts thats old) It was a pain to install the turbo I got on now.

Hope fully u guys can shine me some light for me. Thanks in advance. C the noob

GT2871R.

http://www.atpturbo.com/Mercha...e=GRT

i bought a GT25R .86 housing there is no way that it will fit with out some major modification of the mounts and or compressor housing. it would be more cost effective to go with a topmount manifold and a t3/t4 50trim with a .48 or 63 housing.

for the 1200 it cost for a BB turbo you can get a manifold,turbo,External wastegate, and limitless options for the turbo that could best suit your needs.

the GT28R is .64 A/R is it not?? I'm looking from teh same website u are showing me the link. I maybe wrong. Fallen I've got a SR T25 with the .80 A/R on mine, good improvement over the stoky. but not on the lower end. if u want it, I'll let u know,,it's been rebuilt before I install it, and have about 6000 miles in it. Good luck on the re-install of ur CA. C

Post by **Not_a_sr** » Thu Apr 21, 2005 6:58 pm

yeah it is.

gt28R .64 Gt28rs .64or .86GT2871r .86 this would be my choice, fast spool and capable of at least 350-380HP.

the GT25r i had is this one. http://www.atpturbo.com/Mercha...e=GRT with the .86 housing would have no doubt been way too laggy

IMHO, a CA should NEVER have anything larger than about a .64 on the backside if you want to street the car at all. I'd have the .64 gt28r if I had my choice.

Post by **mbmbmb23** » Fri Apr 22, 2005 6:01 am

The GT2871R comes in .64 ex A/R also. You may look into that. It's the same as the GT28RS but has a 71mm exhaust wheel instead of 60mm.

i agree with ryan on this one..

Post by **r34 gtr** » Fri Apr 22, 2005 8:56 am

whoa whoa whoa!! hold on there chief. neither of those turbos will spool up any sooner than your sr t25. my gt28r doesnt do anything until the car is over 4 grand and under a heavy load. for the price, i would go with an externally gated t3 manifold and a .48 trim t3/t04b like dee is/was using on his girlfriend's sentra.

youll also need to remove all the heat shields from the manifold and stack a few manifold-->turbo gaskets to make it clear. you could also take a dremel to the manifold if you wanted.

and any way you look at it youll need new oil and coolant lines. oh! and you will need to use your stock ca o2 sensor housing as its the only one that will allow a gt28 to clear the steering column.

You've got more energy than me Tim. I wanted to say all that, but I didn't feel like it, so I just answered his question. Sorry guys! But as Tim said, for that kind of money, you could have a top mount hybrid with a quicker spool and more power.

Post by **Not_a_sr** » Fri Apr 22, 2005 4:57 pm

gota go top mount! you blow a turbo you loose 4-600$ you blow a BB turbo 700-1300$.. a .48housing on a T3/t4 will spool just as fast if not a tad faster then those t25 GT hybrids they are making.

Post by **float_6969** » Fri Apr 22, 2005 5:35 pm

I couldn't agree more...

Post by **Loofee95SE** » Fri Apr 22, 2005 6:13 pm

Good to hear, I've been waitting for ur input Tim.then how about a regular T28 from S15??will it be worth my $$ I really don't want to go Top mount. Like really really don't want to. and SSautochrome just don't make me feel safe. But more of u guy oppinions will be great. C

Post by **Not_a_sr** » Sat Apr 23, 2005 7:48 am

why go SS autocrap, there are better solutions out there for not much more money.. you just have to ask around. do you already have a 3" Downpipe?

my log cost only about 275. its a little more after ceramic coating. and a log wont break like those thin tubluars.

Couldn't have said it better myself. Those gt bb units are cool only if you have the supprting mods to accomodate them. But just for sheer fun, the above mentioned will be more than sufficient for most of you CA lovers out there.

hey man, where did you get the downpipe and log manifold? did you go custom?theyre the only things holding me back to go top mount.

Post by **Not_a_sr** » Sat Apr 23, 2005 11:19 am

we have yet to build them since im waiting till my car is brokenin to take off the stock t25. once its broken in we are building a top mount log. we are also making the downpipe adapter . it will be a month or so till i have them made. im having all my stuff built by my fabricator. and we are still pretty busy with mustang turbokits.

Post by **float_6969** » Sat Apr 23, 2005 4:34 pm

any plans for mass production on the log mani?

Post by **Not_a_sr** » Sat Apr 23, 2005 6:27 pm

Post by **mbmbmb23** » Sun Apr 24, 2005 5:10 pm

What if you used something like this:http://www.horsepowerinabox.co...2.htmwith the T3/4 turbo and OEM manifold..........do you think any of the Skyline turbo elbows would bolt up to the T3 turbine housing and an SR downpipe?....what about a Skyline downpipe? Just and idea.

-m

Post by **Not_a_sr** » Sun Apr 24, 2005 8:33 pm

i have a few similar to that, i usually only sell DSM versions.

you can almost get a log manifold for the price of that thing!!!!

being the stock manifold is bottom mountand sits the turbo almost on the motor mount the larger t3 or any other turbo for that matter will have a real difficult time fitting. without some major cutting and grinding of the mount and compressor housings it aint goin in there.

it is so much easier to go top mount then trying to fit a oversized hair dryer down there. and trust me ive tried with a GT25r/40

Post by **Loofee95SE** » Mon Apr 25, 2005 5:51 pm

alright u treadjackers........how about the T28 from SR??

Post by **CA19DET** » Tue Apr 26, 2005 4:38 am

i thought i would chime in here

i have the TRUST mnaifold which places the turbo in the stock location, BUT i am using a T3/T04E with the 50 trim compressor, i had to modify the mount slightly but no big deal. i am sure a T3/T04E wiht a internally gated .48 A/R turbine will fit under the stock manifold wiht an adapter plate... remember the plate will move the turbo a little lower than normal so it would clear the manifold runner #1, but will need to have the mount cut a little.. dunno about the LHD thing..

i like the idea of the S15 T28 more though...

use the extra cash and get some cams

look at he precision turbo T3/T04E's, get the stage 2 .48 A/R internally gated unit and get the HKS actuator...
