2g 50 trim install questions

[96gstdsm]

I did some searhcing but couldn;t really find any helpfull info so thoguht i would ask. I am still undecided on which turbo i am going to go with. i was thinking evo3 but now my attention has turned kinda to the 50 trim or even 57 trim turbos. i am going to be using my car as a dd only! how is the lag on the 50 or 57 trim compared to the evo3? Also what is required in addition to the 50 or 57 trim to install it on a 96 gst? any modifications needed? what in all would i need to buy to install, and is it hard or harder than the evo3 to install? if i were to just install the 50 trim on a stock setup would it give me more power than the evo3? (i am going to do all the supporting mods though!)

I am just nervious that i will make the wrong decision on which turbo to get and then be unhappy. I want my car to be much faster than stock and pull all the way to redline! i was hoping to get somehting around the 5 second 0-60 times or like maybe low 13's or somehting 1/4 mile lower would be fun too!

If someone can tell me what i would need to say have my car be approximately around the 5 second mark to 60 that would be much appreciated.

what sort of difference to you feel with a 50 OR 57 trim compared to the stock t25? is it massive? like a couple seconds faster 1/4 mile? Also where would be the best place to buy the 50 or 57 trim or maybe even 60 trim if people give good input on that. cheapest and most reliable vendor.

Sorry for the newb questions but this is my first tuner car so not used to turboes yet.

if anyone has any dyno graphs that would be very helpfull as well. thanks --ryan.

The 16G will spool quicker then the 50 or 57 trims. The 16G will make for a fun quick fwd DD. It will also be the cheapest route in terms of doing things the correct way. No turbo would give significent gains in power or be a good investment without the proper supporting mods. I posted my thoughts on your fuel set-up for either of these routes on your other thread. The 16G route truely only needs fuel support, but I would go witha FMIC just to keep everything cooler, but this isn't needed a stock SMIC can cool it enough long as your not pushing higher psi levels, if you want to go 16psi and wanted a cheaper option then a FMIC then a supra SMIC would do the trick nicely.
Now with the 50 trim and 57 trim, you will need a FMIC, fuel mods touched upon in your other thread, and I would do 1G big rods, have them shot piened(sp?) for added strength, with a set of forged pistons from wiseco or ross racing if going 19+psi. Oh yeah for either set -up you will need to upgrade the 2G BOV, it leaks at about 14psi. Also if you stay internally gated with either option you will need to upgrade the flapper, and port the hot sides of the turbo, and port the o2 housing, this is to help try and aleviate boost creep, but I would think with the 50 or 57 trims you would need to go externally gated no matter what, but lets see what someone else has to say.

What kind of difference? This makes me laugh, it will be a huge difference...that is long as you have all the supporting mods, without those supporting mods, I dont care how big your turbo is it will get spanked by a stock 14B or T25 that is supported. As for times, there you are hitting bench racing. It will not make you a couple secs faster, maybe with an AWD but us FWD guys need a decent amount of mods to hit good 1320s. the most inportant mods you can do when upgrading are tuning...tuning...tuning....seat time, and a clutch to hold the extra power that your making on your properly supported turbo. Dont expect to run a decent time on your first run, you need to get to know your set-up, and know how the tree works, and ghet the proper clutching technique as to get the quickest 1320 with a good 60' with minimal tire slippage, a little is good but too much will kill your time. Oh yeah for us FWD guys its not all about power, its more about a well roiunded set-up, lightened car, and a good suspension set-up.

The BB 50-trims spool almost as fast as Evo III. They both require certain things for installation. It all boils down as to what your goals are.

I dont want to make a track car. i just want to make the car feel very fast and it will be my dd. i would like to get 0-60 numbers around the 5 second mark, a little under would be awesome also!! just was wondering what it would take possiby to get numbers somewhere near there. either with evo3 or the 50 trim turbo. i know with the evo3 setup i have been told that i would just really need the install kit for that to be an easy bolt on. what about the 50trim?
I do plan to do all the supporting mods first before installing any turbo, just having my car worked on now so thought i would figure out what i wanted to install on it. I dont mean to do any bench racing i am just trying to figure out what it takes to get what approximate types of performance with which turbo set up. i just w-dont want to get the evo3 and do all the support mods and then wish it was faster.

And for the 50 trim new pistons and rods would be neccessary?

 

[brute]

The 50-trim just requires a couple different things. You probably need to pull oil from the filter housing. If it's ball bearing, there needs to be a pressure restrictor somewhere in there, as BB units need less oil pressure. But you need to do some mods to the 2g stock system for a 16g to work as well. How much money do you have? A BB 50-trim will run you like $1000, not including everything you need. The 16g is a great turbo, and you can get the "2g total solution" for fairly cheap.

Edit: pistons and rods would not be necessary.

Derek I only mentioned 1G rods, and forged pistons if he goes the 50 trim route and goes 19+psi, its one of those things that I wouldnt want to break, by staying with stock cast, yes I know 1G rods are stock cast, but they are strong, and yes I know the 1G rods, and 2G pistons are liked by people but the maching costs to have the pistons match the rods, you might as well have invested in forged pistons. Also yep he will need more supporting mods, but I was merely giving an over view, and leaving the nitty gritty stuff for later on when he desides on a turbo.

ok what about if i dont buy the bb 50 trim? i saw a 360 thrust one i guess thats what it's called for like under 800 i think maybe it was 699 i think. how bad is the evo3 on gas? cause i commute about 70 miles a day to work and this will be my dd. so if it is a big difference that would make me lean more possibly to the 50 trim. but faster spool i think would be more exciting to drive with. as quicker power i find to be a little more fun. i am just worried that even with supporting mods that the evo3 wont be as much power as i will want to have. might be because i dont know enough about the turbo yet probably as well. Cause i see that it is a small turbo and all. well after installing my new clutch i will have ###### somehting like 1 g on hand right now to spend.

I dont mean to do any benchracing but with the evo3 and the supporting mods(fuel kit, fmic mbc, 2.5" turbo back, intake, ) any approximate power a set up like this would have? or been known to put out? i'm installing the act 2100 in a day or two so would have that as well.

would it be comparable to the 50 trim with these same mods?

A regular non-ball bearing 50 trim will spool up slower than a dual ball bearing 50 trim. A non-ball bearing 50 trim is dry bearing (uses oil to cool only) while a dual ball bearing 50 trim is wet bearing (uses water and oil).

There are plenty of EVO III 16G vs 50 trim threads that will answer your questions. You will spend more than 1k in supporting mods alone before you get either turbo. A search for "50 trim evo 16G" will give you all the threads you need to read up on.
