In most cases the smaller "no cut" street FMIC's are only good for 16G's at best. I tried the dejon street with a 50 trim and could only tune for 13 PSI!!!
Spearcomakesthe bes cres, not much to argue there. www.turboneticsinc.com gives the different spearco cores and what they can handle. I have the 2-221 which is a top to bottom that did not require cutting. RRE sellsitfor $590. No pipes. I got mine for $400.shipped with a short route IC to TB pipe on www.dsmtrader.com. Do a search for spearco every day and you willfind a great deal. Recently I saw one like mine, polshed with both upper and lower pipes for $500. Mine is ratedfor 760HP(1 run or 2 before heat soaked) and flows 1080 CFM at 1.5PSI drop. Mark

Thats not true. The street cores should be more than enough for 50 trim hp numbers.
Yep, it's the intercoolers fault because you can't tune no more than 13 psi. :rolleyes:
 
I also have the dejon race core and I love it too. No complaints here. I'm running without a front bumper support. I feel that is the only way to go with such a huge core. Why get a huge core when you'll be blocking some of it with the bumper support.

Angelo I switched to the spearco which is only 16% larger than the dejon but 57% more cooling tubes. I now run a 60-1 at 20 psi. How does tuning play into that?
The dejon would only allow 13 psi before excesive knock, into the 20's,now with a turbo that can flow more I get no knock at 20 psi. Wideband, MAFT, keydiver and Scanmaster.

PS: I am only offering what happened to me so others do not make the same mistake. I can oly speak forthe dejon street which is a good bar&plate FMIC. Dave himself was concerned that the IC wold be marginal but my car is too nice to cut the bumper.By the way nice time with yours, congrats!
 
SBR street kit...799shipped awesome kit...I have their racecore and my install was pretty much flawless. Their streetcore would probably suit you and you virtually get to bolt it right up.

thnx SBR :rocks:

Well running stock like boost on the Dejon fmic gives me the impression that you were hardly overworking,heatsoaking, or choking that intercooler. Let alone working that 50 trim anywhere it needs to be. So it would have something to do with the state of tune the car is in.
Maybe you where pig rich, and since your running alitte more boost with a bigger turbo the car is leaning out to where it should be. :confused:

Put yourself to the test and crank some boost up to 25-30psi range then report back about knock counts. :thumb:
 
Angelo the street Dejn could not handle the flow ofthe 50trim. Dave even had doubts that thestreet would handle it. What would be the point of running 25-30psi on a stock block with 109k miles?? I now run a 60-1 which can flowmuch more than the 50 trim. When I switched from the dejon to the small spearco my boost went fromthe 13/14 psi it was set forto 18 psi showing that the spearcois a much more free flowing IC. I am not posting to argue. Just letting guys know what experiences I had because I did not want to cut the bumper on a very nice exampe of a '93 AWD Talon. Perhaps you should crank your 18G up to 25psi since you are a better tuner thani. Use pump please. Even though you are a more experienced tuner does not mean I am not capable of reading my gauges and meters.
You should not recommend FMIC's that are too small/inefficiebnt for the turbo's being used. If I get my 6 bolt rebuilt I will try 25/26 PSI on race as nate at SBR said I would really enjoy the results!
OH, if the dejon worked I would not have sold it. Dave does fine work and I highly recommend his products of which I run a few. mark
 
Most of the street kits do. the Dejon street does,just relocate the PS line I think.There are often good kits on dsmtrader that come with piping for decent prices also.

Kinda makes you wonder how on earth a bone stock DSM can run 13 psi with a 14b turbo (instead of a 50 trim)and sidemount intercooler(instead of a 15X7X3 FMIC) for over a decade without any excessive knock problems, doesn't it?

You probably had a bad boost leak with the Dejon setup. There is no way that intercooler has 4-5psi of pressure drop. Even Dave from Dejontool will tell you that. :)
 
what if you just take out the latch support and put in the FMIC somehow? i dont have the a/c condenser anymore. Would taking the latch support out and another PS cooler help make room for a core that way you dont have to hack the bumper?
 
I don't run a latch support and mant FMIC's become the latch support like the buschur FMIC's have a tab weldedon the top of the FMIC that bolte o the latch.

I've never wondered about that. Obviously you have. Fact is the 50 trim flows 75% more than the 14b.The street FMIC must not flow 75% more than a stock side mount. That I wondered about. Dave himself was skeptical that the street IC would work but thought perhaps 18 psi would be OK. I did/donot want to hack my pristine bumper so I sold a 2 month old FMIC for the Spearco. Just letting guys know how I found the street version to perform. Each must make their own choice.

Perhaps or maybe the cooler weather when I ran the spearco. I like Dave and his products and am using many now. Even dave from Dejontool will tellyou that the street version is more suited to a big 16G at best. mark

I have for many years. It spikes 25 psi and settles down to around 23-24 psi,yep that's 93 octane piss gas. Minimal knock in the 5-7 count range- 4th gear. But hey, I'm not a pump gas warrior so I don't care anyway. :D "cough" starion intercooler "cough"

I never said you couldn't read your gauges or meters. I just thought there must have been a issue in your tuning after looking over the logs.

Your right. I know I shouldn't. :boring:

So, if even a stock DSM doesn't have excessive knock problems @13psi with a much less efficient 14b and stock sidemount intercooler, why would you have excessive knock problems @13psi with a much more efficient 50 trim and FMIC? The street core might not be the best choice to try to get the most out of the the 50 trim that it is capable of @30 psi, but even Dave said it'll work up to 18psi.

I'm not doubting your experiences, but i really doubt the street FMIC was causing excessive knock at 13psi on a 50 trim . There must have been some other issues with the car.

LOL I have a Dejon Street FMIC with a td06/20g. Running 20psi easily with 93 octane, NO knock on WOT.. Also, I don't have a wideband, so I'm just pullin the tuning out of my @$$.

I just posted up a spearco fmic top to bottom setup in the classifieds for a real decent price,
 
I was tuned for 18 psi with no knock on my stock sidemount and a greddy tdo6 18g, so saying that a small front mount like the dejon (15x7x3) can't handle 13 psi from a 50 trim is just not true. My brother has a small front mount (14x8x2.5) on his gvr4 and a pte scm44 60 trim running 24 psi with no knock on pump gas. It was obviously something to do with your tuning or something wrong with your car to make it knock with 13 psi on a dejon front mount. I currently have the sbr race core and i like it a lot. However I also had some customer service issues with sbr, but they were resolved.
 
It was pointed out to me by someone who remained anonymous that i have been acting, well I would say "obnoxius". I was not aware that I have had this attitude for some time which makes it even worse. All I can do is apologize to those I have offended and ask for their forgiveness. Please PM me if you can find it within yourself to do so. I had thought I remained in the back ground until I had experience to offer but apparently not. I cannot explain why I had trouble with the dejon as it cost me since I only owned it 2 months.
Another member fromCanad had the same RS49 ans with his stock sidemount could also only get to around 12 psi and that was after some months tuning and in temps below 32*F!> Well guys sorry for the atitude and thanks for letting me know. mark
 
I dont think you were being obnoxious. Some people are easily offended I guess.
