Turbo upgrade recommendations based on setup?

[jk50b]

Hello, I just bought my first turbo eclipse a few weeks ago its a 1997 GSX, running 15 psi, on the stock turbo with rebuilt engine and transmission with 2k on it and stage 2 clutch. I'm looking to build it up a bit more to be around 350hp, but not to built due to the fact it is my DD, I am looking to upgrade my turbo and maybe run around 20psi safely for everyday driving, I'm looking for feed back on maybe the best turbo to purchase for my setup right now, or what id have to upgrade to run a larger turbo safely and also if i should do a swap or build up the engine bottom. Any feed back or advice would be very appreciated, thanks.

fp big t28,14b,16g, or a 20g.

You have some options.

Edit just read your profile..Your 550s are gonna be your weak point,and where you should start.

 

[jk50b]

What turbo would you say would be easiest to bolt up and require the less amount of work to be done to the car, while still supporting 350hp?

Edit: Would you say maybe upgrade them to 700+ and a walbro 355 be good enough?

 

[Bud92gsx]

The obvious answer would be 20g.So you have more room to grow past 350.But then again some 16g tunes have reached over that number.

 

[my dreamt dsm]

20g is like walking to that hp you wanted. 16g will be like running.

 

[jk50b]

so if i buy the 16g, what modifications will i have to do to the surrounding area? and what are some good company's to buy a 16g from?

 

[Bud92gsx]

Company no..Hit up jusmx141 he will hook you up with a fresh rebuilt turbo.

On a 2g to run an mhi turbo you need to mod or get the install kit.I'll let someone else explain that better.

 

[jk50b]

and also if i run the 16g at 20psi, what modifications would i have to put into the internal engine like lower end and top engine to make sure im safe and not blowing any rods? The car isn't going to be beat on beside the occasional beating i may put on when going down the street or track once in awhile..

 

[Bud92gsx]

You will need no internal mods to run a 16g.Cams help for sure i seen you have some 262s.There fine on stock springs and retainers.

These motors are bulletproof if the right mods were done and a good tune was put on.Bad mods and bad tune thats a bad day trust me.

When I started my first I ditched the stock turbo and ran with a 18g they can push over 20 without a lot of mods it will work with the stock DSM flange from the exhaust manifold to the stock o2 pipe. And it will even work with the stock intake pipe. The 16g and big 16g work fine to I personally would hold off from jumping to a 20g to fast to be honest because of fuel cut unless you have a 255 fuel pump a FPR and 650 injectors. But that's my opinion really man. It really depends on the mods you want to do and what you want to do with your car. Remember the larger the turbo the harder it will be on you stock internals.

Evo III 16G will outspool the 20G but require more than 20psi to make 350whp.

If you're dead-set on that horsepower number, on pump gas, I'd say TD05H 20G for sure.

 

[jk50b]

so just to make sure i got this down so i can go ahead and make my purchase, im going to buy a big 16g turbo, increase my injectors from 550cc to 750cc already have a 355 fuel pump, and im going to buy a FPR, but once i go to hook up the 16g with the installation kit will i need to change my headers( which are 3in magnaflows) and will i also need to get a new wastegate dump to fit the turbo? and sorry if i sound noobish im kinda new to turbos and want this to be right and not done poorly..

 

[99gstdsm]

by headers im thinking you meant exhaust manifold? the 16g will bolt right up with the 2g install kit, i would recommend getting a 02 housig as the stock one doent flow that great. all you will need to do is rebend the coolant lines off the t25 to fit. they bend pretty easy.

If you want you could read up on the Holset H1C, it's good for up to 500whp and with 20psi and a bep housing you'll see full spool by 3500rpms. Look up the holset thread in the forums and you can find out which one suits you best, best of all is how cheap and reliable they are!

 

[jayson427]

A 16g is more responsive then a 20g but the 20g will be easier to accomplish your goal but spool slower. You would be happier either way because they both will get you good power for a dd. You can find a lot of good deals on this website so I would look around and talk to a few vendors before buying some where else.

 

[evoredy]

I voted 20g--specifically OEM MHI TD05H-20G (take a Hahn Super 20G and shove a 7CM DSM housing on it). If you want a solid 350 WHP, you will get it and be daily drivable. It will not hit like a freight train off the line like a 16G, but this can help if you go to the track to get that traction with our short first gears.

A true OEM un-hacked/unmodified Mitsubishi 20G in a 7CM is also very reliable. I beat the crap out of my 7CM housing converted Hahn 20G (which I bought used), daily drove it at 27PSI, and then re-sold on ebay. I wouldn't sell a turbo anywhere if I wasn't sure about putting it back on my own car. It was oiled from the OFH, no restrictor, and OEM drain line. Never smoked.

BTW, FP has a stupid deal on them right now. Just saying. It's basically a give-away.

I agree, I would definitely recommend looking into the holset side of things, if you wanna keep your stock manifold you can just run a compatible housing, but I would recommend an HX35 with a t3 twinscroll housing.
The proper holset will spool similar to a 16g and make as much power as a 20g.

I'm not too sure what you mean by 3in magnaflow headers, but a 16g or 20g with a bolt on turbine housing will bolt up to the stock manifold and your downpipe no problem. 750cc should be OK for 350hp, but since you have DSMlink you might as well get something bigger incase you feel like seeking more power in the future.

I also vote 20g, 350hp from a 16g on pump gas with a stock block will be tricky.

 

[97_4g63t]

I'm with everyone else on 20g. Like stated above check out FP for their sale and get bigger injectors. From the sound of your posts. I would say to start doing some research on 16g, 20g, injector size, o2 housings, BLT, suspension and anything else you come across. There is tons of info on our cars. Good luck

 

[Awd-laser]

Yea I vote a 20g with a 7cm housing. but honestly with it being a daily i think you'll be happier with a 16g. You wont make as much power but it will feel damn good when you spool that thing at 3000rpm and she takes off.

Listen to this guy! He is the resident turbo guru/rebuilder.

I will also vote for the 20g if you are wanting to make 350-400whp. It will be a lot easier and you can run less boost. Sounds like you have maybe a 3" downpipe and/or catback exhaust??? The 20g can be run internally wastegated. It bolts to the stock manifold and runs a stock O2 housing. I'm not too sure on the install kit requirements on a 2g...
