Beginning The Turbo Install

[dsm77]

The day has finally come. The car is going into the shop in a week or two for the turbo install. There going to dyno, tune, and install everything. Heres my parts list...if you have any opinions...lemme know.

T3 SSAUTO turbo external wastegate
Walbro 155 Fuel Pump
GReddy type s BOV
FMIC
Tial 38mm wastegate
missing link
AEM wideband 02 gauge
boost gauge
fuel pressure gauge
Log style turbo manifold
Vortech Super FMU ( using instead of my SAFC NEO)

Im going to keep the internals and injectors stock because i dont have the $$$ to do that rite now so I'll be running at 6 or 7 PSI safely for now. Tell me what ya think.

 

[Splitpi]

I don't see a turbo.

 

[JayRolla]

Get some 450's in there, I would be skeptical at that boost on the small injectors and I dont see turbo either. Whats the missing link??

 

[ILLiCliPSE]

2 wastegates? No turbo?

 

[bushy]

whats a walbro 155 fuel pump?

I think that is the turbo he's running. Whatever turbo that is though. Unfortately, I've heard nothing but norrible things about SS Auto turbos.....

 

[DJYoshaBYD]

they make garbage equipment... I know a few cats that used SSAutoChrome stuff and they said that the turbos break and even one guy said that it looked like the turbo was glued together... just make sure its good when you get it

 

[Cs4g63]

bushy- I was curious myself about the pump.
The walbro 155 appears to be a pump used in Fords.

He will be fine running 7psi on the stock injectors, 255, (i am assuming he meant) and an SFMU. That is a basic fuel setup when turbo'ing a 420a. It is about the limit, though.

About the Missing Link, his 420a does not use MAS to measure air, it uses a speed density system. The main sensor in a speed density system is the MAP sensor. The 420a ECU will cut fuel the moment it sees boost, so in goes the missing link. Basically, it is a check valve with an insanely low cracking pressure. Prevents the ECU from seeing boost, allowing you to mechanically control fuel during boost, via the SFMU.

Missing Links have been known to crap out, and the electronic FCD is the popular alternative.

only 7 psi? sounds like your holding back a nice set up. and look up dsm link its the best tuning sofware in my opinion and it has a forum to teach you to tune. also sounds like you have a lot of tuning and logging equipment for an essentially stock fuel system. but the set up sound like a good starter just missing a few peices good luck.

I think I would just buy a hahn kit, most of these diy kits turn into disasters. I am not saying yours will but I have seen it happen, hahn kits lay down some nice times they got a 13 second slip out of there stage 2 with fmic upgrade and 3 inch exhaust and that was it. .

The guy has a 99 NT, which uses the 420a Chrysler motor and ECU. DSMlink will not work for him, or any other chip or eprom replacement. He will tune with the SFMU on that setup.

dsm77: With respect, and nothing against these guys at all, they are trying to help, but unfortunately dont fully understand the 420a. Perhaps if you next posted in 420a Bolt-On Tech (which is open to New Members) you would get more accurate responses. I am sure if you had a 1gnt, their advise would be sage.

 

[SinaiTSi]

Dsm77 where did you go.........

you need to read this before you put that SS Auto turbo on.

 

[98gsspy]

HAHAHA THIS IS WHY YOU DON'T USE SS CHROME==>

DSM77 just got one question why are u going to tune with a Vortech Super FMU instead of a SAFC NEO? Just curious.

Because, as you should know, you cannot add fuel under boost on a 420a with an SAFC, because of a limitation in the ECU. You can only lean it out. Not a tuning solution on 2gnt's.

Read www.2gnt.com for all your 420a information.

thanks for the news flash. i have a 95 i think i know what an eprom is! in my opinion as i originally stated i think he should run it switch out the ecu and due it those contollers can be very expensive and dsm link pricing is not far fromthem yet offers more options. then he will have tuning and logging all in one.

Well that would be some crazy voodoo, using a Mitsubishi 4g63 ECU to manage a Chrysler 420a engine. You do realize the differences between the 420a and 4g63, right?

His fuel management choices are AEM, Haltech, eManage, DFI, 034efi, Portfueler, MS, FMU, and SFMU. (maybe DFMU, speculative)

 

[dsm77]

Hey guys thanks for all the responses. YES i did mean 255 fuel pump. I've done a lot of reading on the SS turbos and it seems like the only crappy product their puttin out are those manifolds and possibly their older model turbos. The newer ones (which i just bought) seems to have perfect and strong welds and is not glued together. My turbo is another reason to keep such low boost....why push a turbos limits when it has such bad feedback? I just want my car to run smooth and safe and not have any major failures. Need that little extra kick to a daily driver car. The car also has 82k miles....does that seem like a lot to be doing this project anoyone?

I just want to compliment you for keeping this thread on track and helping the OP sort through the BS.

 

[VelocitàPaola]

you cannot add fuel under boost on a 420a with an SAFC, because of a limitation in the ECU.

Not so much a limitation of the ECU as a drawback of the speed density system used in conjunction with an FCD/ML.

 

[Locke]

Not really, thats actually kinda low miles for a '99. Just make sure the car is in an optimal state of repair. At the very least, do a compression and vacuum check. Should probably check the oil pressure also.

Have fun with that boost.

Jeez people, if you do not own a 420a or know anything about the differences between them and 4G63, please stay out of this thread. Some of the responses I read were somewhat comical. He can not run DSMLink as the ECUs (and engines for that matter) are completely different.

I have heard both good and bad about the SSAC turbos, but from what I am hearing now, the brand new ones are not that bad anymore. I still would never run one, but people have been getting great results with them.

Many people have also had great results with running a custom turbo kit (Not Hahn, Star, etc.) including me. The people who blow up their engines when putting on a custom turbo kit are the people who don't read enough about fuel delivery and don't include a vital component in a basic kit (Fuel pump, some sort of rising rate FPR).

Great job Locke with the info to keep this thread on track. I would have jumped in yesterday, but didn't even see this thread until today.

This thread was moved from the Newbie Forums... that's why so many confused 4G63 members were posting originally. You can avoid that problem by posting in the 420A Bolt-On Tech Forums next time.

It was in the 420a Bolt-On Tech section when I saw it. Oh well, that explains it.
