14B or Small 16G

[91BlackLaser]

My son has just got a 91 Laser with cams, 255 LPH fuel pump, 3" turbo back exhaust and 510cc injectors. We are putting on a 2G maf setup, SAFCII, 2G exhaust manifold and a AFPR. The turbo is worn out (almost 300,000 kms) and I am wondering if we should replace it with another 14B of just go with a small 16G. What do you think?

 

[Whiplash]

Go with the small 16g since the 14b is done. There is no better excuse for an upgrade.

 

[91BlackLaser]

Will the 510cc injectors be ok?

Depends on how much boost you want to run...

 

[Quasimondo]

510's will work, but if you can find some 650's that's even better.

 

[91BlackLaser]

I do not want to run more than about 15-18psi.

I do not want to run more than about 15-18psi.

I would get a set of 650cc's. They aren't too expensive, around 320$ on www.ffwdconnection.com look under go-go juice, and the evoIII 16G would be good for you two if you are not planning on going too crazy with it . Good luck with modding it, also you may find it interesting to look at hahn racing's super 16G turbo if you guys want to go a little crazier then the reg. 16G. It has a 10cm2 turbo housing instead of the stock 7cm2 TH, and since you are planning to get an exhaust mani. aswell this would be the perfect time because the super's need a manifold with a t3/t4 turbo fitting but that all depends on what you are planning on doing with the laser. Good luck to you and your son with his laser

The stock turbo is still building lots of boost, but I was told that it has worn out seals. The car has craped out a MAF because oil is blowing by.

 

[Apeximprt2nr]

I would get 550's since he has the SAFC II, and running about 15-18 psi. They'll be plenty for that set-up. Good for about 20-21 ps( 93 octane gas)

Is your car smoking from the tailpipe or is there just oil in the intake pipe/turbo inlet? Also is your valve cover breather still hooked into the intake?

No, the car is not smoking out the pipe and no there is a small filter off the cam cover. I was told that there is oil in the intake tube. I checked it and did not see any, but the guy who owned it before just changed it.

 

[Spidey]

I would check the turbo inlet and intake tube, as well as the lower intercooler piping for oil, yourself. If the car is not smoking, and there isn't any oil in the IC pipes, and it still builds boost fine, and does not have excess shaft play, chances are the turbo is ok and only needs to be changed out should you *want* to upgrade. Also note that a small 16g is only like $20-50 cheaper than a big 16g when new, and the big 16g will obviously flow more air.

I dont think he needs to buy 650's if he is not going to go crazy with it. 550's should be plenty with an AFPR and an SAFC, use this calculator to help size your injectors.

Now I am thinking of a big 16G. Any thoughts on that?

 

[Lordpaxin]

EVOIII 16g > Big16g for the same price.
if you go with a evoIII - big16g, id say a 660cc MINIMUN on injectors.

You are getting into 'i need a stronger clutch' territory.
is the fuel pump rewired?

Almost time for a FMIC

The more you do, the more you will think you need to do to make it efficient.

make sure you have all the necessary guages, and I personally would have a EGT gauge.
Do you have a Logger, or a wideband lined up to tune your beast?

 

[Lordpaxin]

Oh, and some 7es plugs at .028 gap or so would fit in real nice.

I Had a 1992 Awd with 3 inch Turbo Back, 6Es plugs, wal 190 pump rewired, and a KN filter, running a Small16g on stock injectors, running about 15 PSI creeping to 16-17 on Topend and Would only hit fuel cut on warmer days.

It ran a 9.0 in the 8th mile on stock clutch.
pulled like a raped Ape I think.

Then I had a 2g with an EVOIII + 660cc + FMIC + wal255lph + act2600
@19psi and it pulled SO MUCH HARDER but i never tracked it.

small 16g flows what.... around 50 More cfm than the 14b, and the big16 is about 50 More than that.

The car has a data logger, new clutch and all the necessary gauges. The cool news is that my son got the car for FREE. It is in great shape, a family member gave it to him!

 

[Lordpaxin]

excellent!

the best part is He has a Dad Who is Right in the game with him.
Props To You

One hell of a present. I wish my family would give me a modded DSM.

When running the EVO16G, like paxin stated, you will want a larger injector. You could probably get away with it at 18psi on 510s, but your IDCs would be creeping towards the bad end of the spectrum. It is also never bad to have a little elbow room to work with later on if you deceide to run a little more boost. Although, running any bigger than 650s (or even 650s) using the SAFCs injector compensation can result in less than desireable timing.

Ill stop there. What is this car going to be used for? How old is your son? When upgrading the turbo, expenses can pile up damn quickly, especially when you get by the speed bug.

The car will be used for daily driving and a few trips down the 1320. My son is 16. Another question I have is, I have a 2G maf setup up coming and I want to make a plug and play wire for it. I will have the 2G wire, but it has no plug for the 1G side. Where do I get a plug for that?

Thanks for the kind words. I am 35 and my son is 16 so I still like all the things he does. I have a supercharged thunderbird that I race so we are kinda competing.

 

[talondude4]

I would go 16g, go to www.turbochargers.com they have some special going on.

 

[-DSM2NR-]

Damn, I wish I had a dad like this. Seriously. My dad on the other hand is against the thought of me spending my money on my car. I applaud you.

Heard that.

 

[91BlackLaser]

Heard that.

My dad still thinks I am nuts for putting money into a car. He does not approve at all. He is now pushing 70 and years ago he had 440 sixpack cars and insane muscle cars that are now worth a fortune. He used to street race and all that. I just say that he is getting old now and does not think the same or have ANY fun at all. I for one take care of my wife and two kids and try to relate to my kids so we have great communication. I never want my kids to shut down and feel they can't talk to us because we have nothing in common. I listen to rap and heavy metal and never want to get dull.
