dragstr4g61t I really like your setup. How does it drive on the street? I think a 16g might be a bit small for me as I will most likly swap in an 4g63 when the 61 pops :D I'm new to this 4cyl turbo thing so I can use all the help I can get! I've been racing Camaro's for the past few years the last one being an 02 ls1 car and all it took was a cam, bolt ons and 150 shot in a 3600# Car to run 11.50 @ 120 on my first pass @ Pueblo lol
I sold that car to Jared a few years back but my setup was very simple. My motor was stock from throttle body to the oil pan.

Mods at the time were:
pte 50trim/mitsu bolt on housing 7 cm (externally gated)
hks 272's (used)
fis 1150cc inj
ecmlink v2 (used)
slowboy racing cast manifold w/ 38 mm Tial W/G
Fidanza alum flywheel
ACT 2100 clutch (used lol)
hks bov (used)
Evo 8 FMIC ($100)
2g Maf
single walbro 255 with 30 amp wiring.
Running e85
...and slicks for the track

Everything else was bone stock, no fpr, intake manifold, ignition upgrades, tranny...all stock.

Jared and I were both able to run 10's on this setup, it was simple, easy to tune and ran for over 2 years of hell bent driving with thousands of street and strip pulls boucing of the limiter.

It was very streetable and I even daily drove it in the summer for 2 months averaging almost 30 mpg (no boosting lol) on e85. The 50 trim responds just like a ported 16G and was building boost just above 3000 rpms with 20+ psi in the mid 4000 rpm range. It was also very responsive between shifts like smaller turbo's. The larger turbo's Steve and Jared are running now litterally have lag between shifts unless you have very agressive NLTS settings. I felt the balance of street/strip was perfect for what I wanted. Sure the 61 mm and larger turbo's are fast but in most street situations and even at the strip, the smaller 50 trim was quicker and easier to drive fast.

Number one thing that can't be denied about that car, which I also feel is the number one reason it was so fast. It is/was the lightest documented CSM ever that was done and racing. Not hard to go fast when you weigh less than 2100, and even under 2000lbs if I remember right.

Great motivation and inspiration guys! Im not taking any weight out of this car and I'll be keeping all the stock parts just incase I ever decide to return it to stock. Now I just need to find parts :D How does ecmlink work as far as my ecu? Do I need to replace it or will it wire into my existing ecm? Again Im used to camaros where you just plug your laptop into the aldl port and tune away lol

Essentially it is a programmable and removable chip that sits in the daughterboard.

Go here for details.

Looks pretty straight forward. But I probably wont be able to find a used one right? lol So I need to find a 90 eprom ecu? Or is it possible to use my 89 stock ecu? Also Whts best to run gm maf or sd?

Your stock ecu might be an eprom. It can be converted if so. I am not 100% sure, but I would assume even if it is not, your ecu if not an eprom can be converted. They did an eprom conversion on the summit with a regular turbo 90 ecu. You can also use a 91-94 ecu, you just have to swap some wires. No big deal, just a matter of getting the tach to work. Which you can wire directly from the ecu to the back of the gauge cluster anyway. Plenty of ways to skin that cat.

We prefer speed density as it is easier and cleaner, but any mass airflow sensor will get the job done. It is all in how you want it to look. I like a nice clean look so no mass air systems here. That and speed density will go farther than you need and won't be overrun.

Has a lot of answers. Very easy to check if you have an eprom or not.

Amen to that, the car weighed in at 2175 with me in it and Jared was around 2250 when he went ran 10's on the same setup. But even so if it was full weight at 2600 or so lbs with driver, I don't doubt it would have still trapped the 120 mph he is targeting. Plus the extra weight will just help add some load and spool the turbo a little faster :wink: .

That entire setup cost me less than $4000 for everything including the slicks and are all very easy parts to source used. You could even eliminate the external gate/exh manifold and save some good money too since I don't think it was a key element. It just sounded sick when the Tial opened up.

I went with a maf setup since its closer to stock and was very easy to set up. I also wan't over running the maf with that setup and so it didn't require making a big change and having to spend all the time getting it to run right.

Do you guys think that $600 pte 6262 is overkill for the 1.6 or should I hold off and find a deal on something a little smaller?

It is a 50/50 toss up. For the deal I would make it work. Especially for the potential. Then again it is a good sized turbo that will require a lot of work to use correctly. Both in support and fitment. I am a go big or go home guy. 120mph can be had with less, but you still need all the supporting stuff.

That is a great deal on a badass turbo but like Steven said, it will require a lot more to get it to perform properly and the rewards would speak for themselves. I wouldn't expect a 1.6l to be able to spool that sucker till well after 5k rpms in 3rd but with a higher rev limit it won't matter to much once boost hits.

Goodluck with whatever you decide to go with. There is a good group of helpful guys in the area.

You get what you pay for. At that rate we would rather you get a holset turbo.

I hear ya on the get what ya pay for thing. I guess I need to set a budget and plan from there. Sounds like the big turbo ecmlink thing might be out of my budget once I buy all the other supporting mods.

Honestly the first thing I would buy would be the EcmLink....from there you can go any direction you want and it will be able to make full use of any modifications you do along the way. With the Link you could even build up the fuel and maf systems and decide on a turbo near the end since it is usually the most expensive part.

I agree. Money well invested. Will comnpliment anything you do to the car. You will need a dsm mas and 450's if that is indeed your first mod though.
