Default FP 18G installed. Info for you

Hi,

I decided to drop a line and tell you waht I think of the FP18G.
It is a Mitsubishi turbo with a 7cm housing. It is not water cooled.
the flow is [email protected] versus stock turbo [email protected]
My spool time is around 4k but my car is not well tune yet.
The turbo feels laggy and it definately got my car slower when driving in town. The good thing is that now I get 16-17-18 or 20psi in any gear unlike before that I could only get about 9-10psi in first etc.

If I would have to compare the performance I would say that the 18G will kill the stock turbo performance in the 1/4 mile but it will be very questionable in town . I use to have a full stage 3 in my car before the 18G turbo with new injectors, now the speedometer goes up quick, you past the 60mph and the speedoometer keeps going almost at the same rate from 0-60 than 0-100mph.

My best suggestion is that you get the specially made oil line(stain steel flexible 20")from Forced performance otherwise you might have to bent the stock oil line to make it fit, believe me ,not worth it. Last but not least be aware that the stock bolt that keeps the oil lines in place might be to short for the new oil line(the stock screw only goes in 3 threats with the new oil lines)

Good luck out there and I will post my 1/4 times soon.

My mods :

18 G fp turbo
PE 650cc injectors
Walbro fuel pum
Borla headers
sti scoop
tmic from Turbo Xs
Gredy cat back
hks Down pipe
tmic gt Spec spliter
CAI intake
Utec computer
Lineage grounding kit

I don't understand the issue with the factory oil feed line, on the prototype install fitting it was a breeze. Were there more than one oil feed line designs over the years?

Grocmax,

The stock line can be install BUT it must be bent. When I saw the stock rigid oil line I was glad that I choose to get the upgraded stain steel flexible oil line from Forced performace. The stock line would eventually collapsed(it has a very small inside diameter).
The shop that installed my 18G turbo told me very clear that they were not going to bend the stock line to fit it.

I have another friend with a 20G turbo from Forced performance and he encountered the same problem, the stock line will not fit straight without mods).

As per the so called"bonji bolt" that hold the oil line to the turbo, it is simply to small on diameter, the stock bolt will not properly secure the upgraded oil line to the new 18G turbo. You only get 3 threads to bolt it into the turbo(not enough considering that you must use a crush washer.).

This is my first month with the turbo and so far so happy, I am running the turbo with the stock 15psi waste gate spring setting which in reality I get 16psi steady with my mods. I get to read up to 18PSI early in the mornings when I go to work.

This turbo is laggy, as I mentioned before, the response is not near of what it was before with my stage III and stock turbo . This turbo should be the ideal turbo when you use it with a 2.5l block and/or a close gear ratio gearbox.

I will be tunning my car with AZScoobie very soon in Phoenix and I am planning to take the car to Dynocom in Phoenix as well. The turbo is even quieter than my stock turbo and the power is very lineal/progresive.

Good luck and stay tuned!

Question,can someone help me to post pics of my 18G turbo and oil line on this site?. My e-mail is [email protected]

Thanks

The bend required is no issue to the integrity of the line. The difference is in the body size between the TD04 and TD05 frames, it is very very minor. I don't remove the line at the head end, but the turbo, and bend it up slightly and slide the turbo in/out under the feed line. Just bend it back down into position once the turbo is placed on the header studs and start the banjo bolt in with the washers while you can still move the turbo around slightly, once all the bolts/nuts are started by hand, proceed with tightening. This is standard procedure for an old fart like me with a subcomponent that is held on by many fasteners in many places- start all the fasteners by hand before tightening any, it insures proper alignment, insures no threads will get cross threaded, and makes it easier to get all the bolts in.

The original feed line banjo bolt will not fit period, which is why a new bolt is supplied, usually screwed into the housing already so it is obvious.

We thought installation was very straightforward, goof-proof, might have to rethink that one and include instruction sheets. Sometimes having years of experience in certain areas you take for granted others will see what you consider obvious, like two bolts with very different thread pitches and lengths that will only fit in one spot.

I'd like to add when you do bend the line, make any bend over several inches of length so it doesn't kink, don't try to bend it sharply. Another one of those its obvious to me deals, but may not be obvious to you.

Gromac,


I agree with you but I highly recommend the Forced Performance stainless steel oil line. This line is great, it is about 20" long and very flexible, it is much larger than stock and allows much more oil through. It looks great in the car and it is very easy to install.

For those of you that don't care paying $65 extra, I suggest you getting it. I assum that if you can afford and upgrade turbo and the supporting mods $65 should be small cash for you..

I almost gorgot about this thread, well, I finally took the car to Phoenix to have it Tuned by Clark(AZSCOOBIE). The shop where I tuned my car was Dynocomp.

I put down 280.3 WHP 255lbs of torque on a Dyno Dynamics at 18psi of boost and 91OCT gas.


Further more I took my car to the track in Tucson(SIR) and I ran a 13.2 at 105. Full interior, 91 oct gas, worn stock tires and a lot of heat and 3000feet of elevation.

So i'm assuming you are using a TD05?

I'm looking for something that has good response.
