Hey guys I'm a big reader forTec ? when it comes to mods for my 1996 cobra. But haven't been able to find anything about the setup I'm trying to do above.. Well i know that the exhaust manifolds have some type of emissions running off of it. So what all is needed and what needs to be taken off to make this work Besides the Obvious?

your cobra has those plates the open up over a certain RPM (can't remember what they are called for the life of me), but the 03/04 cobra heads/intake manifolds don't have them, so you'll have to do some tuning with the ECU to sort that out.

are you looking at spinning the motor really high? and where and how much are you going to pay for an FR500 intake manifold?

Well the word your looking for is IMRC runners yeah im tracking that there will be gone i already have the FR500 intake i bought its last tour from a guy who did road course racing with a mach 1. It has the new box the fr500 intake comes with the new box, MAF, And all hard wear needed, I have a 97 cobra motor that im doing this build on. But i know 96-98 have the emissions linking to the exhaust manifold and the 99 and cobra headers i have for the 03 heads want need so just woundering what will need to be taken off. Thanks

It sounds like you're talking about EGR. The exhaust manifold can be plugged, and EGR turned off in the tune.

yep, an EGR delete. the OBD II monitor for the EGR can be disabled in a tune, just like the rear o2 sensors can be disabled in a tune. do you have emissions testing down in north carolina? you might want to slip the guy a 20 if you do:bigthumbsup

so the FR500 intake doesn't have an EGR fitting at all? worse case you sell that manifold for like the $2,000 that it's worth and port and polish a mach 1 intake manifold.

Hey guys yeah the FR500 intake has the EGR setup everything is a easy swap for the EGR . IL post a pic when i get back from mission if you have ever looked at the 96-98 vs 99-04 with the C heads they deleted the emissions that runs in to the Driver side exhaust manifold where it bolts to the block. I'm sure its a easy fix just haven't seen details of that in particular change over.

I've been waiting for this thread to come around so I can piggy back it lol. Can you explain how you are going to deal with the IMRC plates? Considering the fact that the b-heads used dual intake ports - and the 03 cobra heads only have one- are you going to modify the IMRCs? Or can you delete them all together? Or do u need to get a new spacer?

Hey richard, The FR500 intake is a direct fit to the 03 cobra heads and the butterflies are built into the intake so there is no imrc runners like on the 96-98. But it has the same TB position as a 96-98 intake, From what i read it sounds like your doing 03 cobra head swap too!

Well any other advice on this switch is welcome, Ive been buying up for this build since last tour so just want to make sure i haven missed anything before i get home and start it.. Thanks Again!

Ohh yeah that makes sense. Yup I'm going a 03 cobra head swap too--at some point. That intake is really rare...nice job on picking that up. I have to figure out how to get the 96 intake onto the 03 heads. I wonder if it will bolt right up or if some kind of adapter is required.

As for you're EGR problem, I'm no use lol..You are a little further ahead than me in your planning. But if I were you I would delete it like Bullit said. Who wants half burnt exhaust filling you cyilinders anyway? lol

Yeah the intake was a awesome find for $2100. I set my mind to be diff all are going with root blowers and or some type of factory modified intake with the 03 cobra heads, so i just wanted to be diff. Also plan on going with a procahrger later..

As for your setup throw the 96 intake away and grab a 99 or 2001 cobra intake, if possible get a mach 1 intake for the setup. The only adaptor plate i know of it for the cobra r heads to a 99 and cobra intake setup. They dont like our b heads.lol

Dont forget to use your 96-98 cobra cams if aftermarket ones are not on the list of things to get as they are more agressive than the newer cams and will add around 12 hp to the ground..

The Frpp intake will fit with the newer heads, the big question is why? Being unique doesn't make horsepower...At $2100 + the cost of the heads you almost could have a Kenne Bell supercharger which comes with it's own hi flow intake (it's $4100)....Don't waste your money...build the shortblock with forged components(or even run the stock shortblock, I do) and put a KB supercharger on it..it's really the best path to making real power without spending buckets of money....
Get some long tube headers on that motor, along with a full exhaust it's money well spent...not to mention the great sound it makes.

Well thanks for the advice But im tracking all the key points above, But i have already completed the buying of everything i need from heads to headers, and im currently looking in to the forged piston from DSS, But im not jumping on the KB wagon even thow its a good one to be on, Gonna go with a Procharger F1c is what i have my eyes on so far..

P.S. Do need some 03 cobra valve covers but done buying til i back home.Which is about 3 months..

2Manystangs, Forgot to mention that the intake isnt just unique, it also adds 35-45 hp over factory intake NA, and 55-65 with Blown applications plus a better throttle response..

Oh ya your right about the intake. I forgot that the 96 has dual intake runners per cylinder, where the 03 cobra head doesn't. That's too bad because 98 intakes are frikken ugly lol.

the 96-98 cams are more aggressive?? I didn't know that. I'll be going with crower stage 2 cams neway, but good to know.

Yeah I agree that most ppl seem to be doing the KB thing, which has kind of turned me off them a little bit. Now I want to go TT!!! lol

Mello, well thats the plan so far, But i am stalling cuz it hard for me to spend more on a procharger than i did to get the ca.lol

What kind of setup are you running?

Im hoping for around 650, but know that once im bored with that the procharger is good to about 1200 i think.

Rich, Well i have thought about TT myself and im just not that perficient with turbos.. Yeah i think im gonna go with stage two comp cams..:bigthumbsup

Yeah I'm not proficient with turbos either, which is why I'm going with a KIT lol. Also, I've got more time than money at this point in my project cause I just bought the engine. So before I buy the kit im going to do a lot of research, and learn as much as I can about it.

i'm running just the basic P1SC on my stock longblock. have you ever driven a car with 650rwhp? there really is no need for that on the street i can tell you that. you're also going to need ot go wider than a 6 rib belt setup. an 8 rib at least, 10 rib if you can afford it, or cog setup if you really want to go at it.

Mello, Well yeah with the kit i have looked at I'm gonna go with the cog belt know its kinda over board but don't want to deal with the belt slippage. As for 650 hp yeah i have drove it before and I'm stunned that you said that to be honest. These days you have 400 plus HP cars coming from the factory not to mention the 5-6 hp shelby,saleen,roush, and of course the vetts.. Not to mention the V6 these days have the same as ours do factory.. Granted its still not a race thow:laughlitt

so to me 650 will kep you in the mix of the fast cars..

Mello Meant to type 500-600 HP.lol

Rich, Well you are on your way to some real HP yourself, with the TT kit i hope your looking for 800-1000. Cuzz with the high boost you will get it.. One of the big reasons for me not going TT is due to my job i dont have time to let my Turbos cool down, and im not gonna get the kit that lets it run so it can be stolen.. So for my life style it will be SC..But whats all you missing from your build?
