port and polish stock intake

[turbo6x2]

porting stock intakes if needed

if anyone is interested I have a place here in Grand Rapids that is more then willing to port our stock ones to get them to flow a lot better will post pictures soon. I win Engineering

I have the ported intake on my car and let's just say it's running a lot better. Idles much nicer, no more high end issues and it's building boost and keeping it where it should be. Now if I can get my higher stahl converter in this week, I'll have some time slips this weekend. This made a huge difference and these guys have an excellent turn around. The job will be done top notch. They are not polishing the intakes though, don't need to since it's air that is forced them, not fuel. Really won't increase anything by polishing. but do a nice job porting. I recommend them 100%

No flame but I have to disagree about the polishing,the wet intake would be the one you would want to be rough so fuel does not puddle or lay down in the port(that's why those dams are on the floor sometimes.The dry intake should be polished to ruduce friction which of course adds unecessary heat.Did they do anything in the inlet area?

I'm going by the information provided by the person doing the work, who did a lot of research on the subject. Not an opinion. just what he found from research. The answer to the actually question is yes. They enlarged it and cut out the excess to help, also lost the egr port and welded shut. I just know this car wasn't running after trying a different modded intake, and now it's running really well. It's just nice having the car actually respond and idle. I know there isn't a vast number of vendors supporting the hot air and just would like to share information with anyone else wanting to improve their car.

Sorry to ramble but,

As long as he is getting that damn restrictive inlet and those teeny ports bigger that's the ticket.
No reason to cut it open unless you are gonna intercool or if you want a huge turbo.
Depending on the price,which should be fairly high considering the amount of time involved this would be a good alternative to the old turbomotion for now.You would'nt be able to polish the inside of the intake anyways so that issue is kind of moot,but if you could it would help on the dry intake.I polished the inlet adapter and the inlet and the ports as much as possible.If it helps or not I don't know but the car runs Very well(see kill section, LOL)for what I have in it.In the inlet area I ground the egr passage down to it's internal floor and welded in a piece of 1" angle alum to make a definitive split for the air instead of it smacking the floor and becoming disorganized and creating even more friction.The design of the intake inside moves the airflow in an "S" shaped path and that creates some friction but also creates the perfect situation for alchohol or water injection.Lots of unharnessed power in the hotair motor and our collective experience brought to this board and others is letting us progress the performance of these non-ic cars to where they have never been before.I might just keep this one and get me another(86-87 next time tho).I would offer to port some intakes like I did mine but I don't have the time.I'd also like you to run the 1" alum angle trick by your Machinist and see what he thinks,maybe he could incorporate that into what he does.

Hey, appreciate it, I know they would appreciate all the input that they can get. I was just glad to have it done. And like you pointed out this is a very time consuming project. What was great about it is they did it in the time frame promised. (we would of been happy even if they hadn't) I sent them jpegs to post on the site to show how much material can be removed and the weld where the egr is (they used a similar idea for the plate) Like I have mentioned I was more then impressed with the power from this one mod. I had a ported one from another vendor and it was an issue. This is simple (time consuming)and makes a large difference. I'm running a larger turbo so this was necessary, but I don't see how you wouldn't get an advantage even with a smaller turbo. More air is more air. Too bad I won't have my transmission and larger converter to go play, but I'm hoping for some nice results anyway. I need more stahl, right now I'm running the converter from the 87 which a 2800 works excellent with, but my mods and such need at least a 3500, it's supposed to be done next week. Then I think there will be another improvement. I'm just trying to help support the cars I love. Yes I think hot airs are cool. (so, to speak) I just would like to try and help to continue to support our cars with more available vendors if possible. They are even looking at setting up intercoolers for these with a lot of the turbo motion application idea. (this takes time) Thanks for your interest and encouragement. Also you need to keep your hot air. Just buy an intercooled one. Two are more fun anyway. Then you can pull out your hair some more... LOL

hey

hey guys just figured i would say if u want to know more baout this you should be talking to turbowrenchhead because he has done one. i bought this intake from him last year and i havent really been able to use it but he said he picked up if i can remember correctly .4 and 4 mph over the stock intake to the one he fixed up. lets see if we could get him to chime in on this topic

Another tip, I was able to hog at least .015" of material from the inside of the turbo adapter piece,looking at it you can see the modified one looks huge compared to the stocker.These little mods by themselves are not too significant but together make a great improvement.The Turbo, Stock, or modified can flow more air into the motor with bigger passages with the same amount of boost to the point where you hit the maximum flow of the intake valve itself.This is why you have seen guys complaining of not so much an improvement with the ta-33 or other upgraded turbo that you would expect,their stock ports are a brick wall to extra airflow.If you can get this big of an improvement with a stock turbo it stands to reason a bigger turbo would not help much until the ports are opened up.

As a sidenote it was 50 degrees this morning on the way to work and traction was an issue,even at 25 mph.I like how it breaks the tires free on the 1-2 shift and fishtails if I'm not under WOT with 16 psi on 94 pump gas.Who needs coffee when you have boost? You car should be a handfull if all goes well,please be sure to post your times right away.Are you gonna run it this year?
