I found this guy that sells EVO IV and EVO V FMIC cores reconditioned for cheap, and I was wondering what the dimensions & also how the flow characteristics of this core would differ from a stock 1993 Eclipse GSX SMIC.

 

the evo 6's or 7's have a core (w/ end takes) thats around 22w x 12t x 1.75 deep (measuerments in inches). i believe the evo 3 & 4 cores are a bit smaller but not much. Its a great flowing tank thats VASTLY supior to the side mount...

what mods do you have? this might be a little over kill on a near stock 1g.

Also, the core is tall... well its very tall for a 1g But i did ask RRE if it would fit... they responded that it would indeed fit, but custom mounts would need to be made.

May i ask what the prices are? i might be able to give you some contacts to some ppl that are selling cores here in the U.S. that are VERY cheap.

I recently asked this question (for evo 7's) on this board... you can look for my post and see some more answers & pictures :P

 

My brother is into the Datsun 510 scene, and he knows someone that posts on his board that supposedly sells reconditioned EVO V cores for like $200. At this point i am not positive if it is that cheap, but i figure if i don't go through that guy, it would be way cheaper to find a used OEM part as opposed to paying like $1000 for an FMIC kit, even though i would have to get pipes made, i still think an EVO core would be a good idea. as to the condition of my car, I have the head torn down, and a set of SS valves and double springs/crower retainers is gonna go in, along w/ a mild port of the head and the exhaust manifold. What kind of boost increase am i gonna see with this kind of setup? BTW, i am running a stock TDO5-14B. thanks for the feedback

 

You wont see any boost increase untill you get a boost controller (but your engine will flow better and be more efficent). most people will run 18psi w/ a 14b with the stock fuel system, you can do a fuel pump re-wire to get better voltage to the fuel pump and thus get a little more fuel... i dont sudgest you try for much more than 18psi, I also recommend getting a 2g MAS, it funtions much better than the 1g, but its not totally necissary since you can pull honey combs and "hack" the 1g mas (i recommend you read vfaq before doing any of those mods).

I sudgest you also look at the rre upgrade path for DSM's, your going a bit "out of order" as far as whats recommended, but the next things you should look at (after the intercooler and ic pipes) would be a turbo (16g or better) 550+cc injectors, a fuel pump (rx7 or supra), but you'll need the basic stuff as far as an air filter w/ air can mod, UICP, boost gauges, egt gauge etc before upgrading the turbo.

You also should upgrade the clutch while its easily accesable (oem wont last), a resurfaced flywheel is usually a must when changing the clutch. RRE sales lightened stock flywheels, clutchs and just about all the parts you'll need. Most everyone (including me) recommends an ACT 2600, but there will be a lot more pedal pressure.

you should also check out the v-faq board which has lots of good info (www.vfaq.com)... And clubdsm has lots of good information you should look at too (www.clubdsm.com). From those two sites you can find just about all the information you'll ever need... You can also get on with a DSM group in your area off of clubdsm... what area of the US do you live in?

Btw, i am planning to do the same thing w/ a evo FMIC... it does look to be cheaper, and you can have the pipes made to your own specifications.

Oh, David brode has a great deal with UIC Pipes that he makes. I'll PM you with info on the evo7 FMIC and DBrodes web site.

 

How hard is it to get to the clutch with the head off of the car? I heard that the whole engine has to be pulled to get to the clutch in our cars. As to the boost, i am totally amazed that it is possible to run 18 psi on a completely stock fuel system, but the whole reason that i took the head off of the car is because of my fuel system.. My buddy was driving my car to his shop to get it aligned, and when he got on the freeway (WOT no doubt) it got all loud and lost its power. Cylinder two lost ALL compression, so we took the head off and low and behold, cylinder two got leaned out and blew a hole clean through an exhaust valve, hence the mentioning of the mild port to the head. If my head isn't cracked, i am gonna get a mild port and anything else i can afford to replace/upgrade while the top of the motor is off. Hopefully this has shed a little light on why i am going on such a back-asswards upgrade path. Anyhow, the car as it stands now has a K&N and 3 in. catback exhaust w/ hi flow cat, and i hacked the MAF, all else is stock, for now. I am gonna have to get of 550's and a fuel pump for sure. (seeing as the stock injectors are yard saled)

So what have you got done to your car? BTW, I am in San Diego, and i just found a local DSM group, so ill have to check that out.

 

Sorry, i thought you had the engine completly pulled... missread your post.

To change the clutch/flywheel... well its a huge pain in the ***... it intels removing or moving the: transfer case, transaxle, axles... etc. Most people pull the entire tranny.

You can look on http://vfaq.com/index-main.html under drivetrain and read the process.

The stock fuel system is very good for any car (infact a lot of 3si ppl will upgrade to the DSM's 450cc injector)... you could also look into getting some 510cc yellow injectors from an EVO, or blue which should be 560cc or 660cc (not sure exactly) for fairly cheap... but a set of 550's is $290 on rre's site. A lot of people prefer a OEM Supra TT fuel pump due to the fact that it is much quieter than most other fuel pumps and flows just as well if not better than the denso and "whinebro".

I figured that you had some sort of engine problem and that was why you were doing engine upgrades.... you might want to check into lifters... i believe they updated the lifters to one that had better oil "flow". Depending on your mileage you may also want to get all the belts replaced (& possibly water pump) while you have everything off... (also make sure you get your timing belt done correctly or you just spent a bunch of money twice)

Are you saying that the injector was at fault to causing the #2 to lean out? i'd make sure to completly investigate that problem to make sure it wasnt caused my something else and prevent it from happening again.

Have you done the air-can mod? the stock air can is very restrictive. i'd look into a Joe P boost controller (very effective and only 50 bucks) and of course you'll need atleast a boost gauge... its wise to upgrade the upper ic pipe at that time as well.

I actually just bought my car (allthough i had been involved with the austin-DSM group before) and have almost finished a clutch and RRE lightened flywheel, i got the car cheap with a bad clutch.... maybe it wasnt cheap enough. I have a boost controller and BOV waiting (got them free ) and will be looking to have a dbrode UICP ready as soon as i get the clutch broken in. other than that my cars stock with the exception of a K&N filter w/ air can removal mod and other free mods.

The DSM groups are very helpfull (they'll either recommend shops or come help you themselves) if you need anything. there very friendly... and due to where you live i'm sure theres a bunch of them. Good Luck

 

18 psi on a 14B was never possible for me, damn fuel cuts.

Evo 5 FMIC is a bit smaller than the 6. The core is 19 x 11 x 2.75.

Here's how it looks on my car:

 

looks great those are actualy 2.75 deep? that actually deeper than the evo6+'s (which would be a better fit on a 1g) correct? (or maybe i got my numbers backwards)

i plan to use a 2g MAS once i get around to needing it. . The 1g mas, even hacked (which produces a lot of cons), is pretty crappy.

Did you just weld on some form of mounting brackets? or what exactly? (it shouldnt be to hard... but its nice to have the info before i get into it). Did you fabricate your own ICPipes by just buying mandrel bent pipes and having them welded together?

 

Actually, the IC isn't not bolted or mounted to anything. It was light enough to be held up but the silicon couplings of the IC pipes, with some clamps of course. And the amount of bumper support i cut of was enough to keep it snugg in place also. I bought the IC pipes from Automotosports because they went stock routing.
