[/font]well iam putting a 98 cobra engine in my 02 gt so far i have the 4v cop valve covers thanks to tollebuilt thanks man and iam getting custom fuel rails to use the stock fuel system i have also coverted my stock engine wiring harness to work with all the sensors on the 98 cobra engine also have done the egr delete kit and the imrc deltes so that i can use the stock comp with a tune iam usint 42lb injectors ported lower i have the 03 cobra pumps in and 90 mmmaf since i used to have a vortech before i blew the motor and in the future iam putting the vortech back on so let me know what u all think if this is gonna look good or what iam getting the car tuned by murrillos since he did my last tunes .

[02silverstang]

well the engine is in the car started it ran a little rought but i will be getting it tuned soon . I WILL POST PICS LATER THIS WK .

[02silverstang]

so i droped off the engine the long block at kotzur racing engines there going to put manley rods and je forged piston and ported heads with 5 angle valve job and stage 3 cams trying to make around 450 rwhp plus 150 shot of nos pete the owner said it is very fesible to get that much power well cant wait and i will keep evryone posted .

[96greengt]

450 out of a 4V N/A ?? are you sure???

[superGT2000]

are 98 and 99s the same motor??

[96greengt]

Same bottom end, different top end.

[superGT2000]

got it...

[Red Demon03]

450 ?? I have an 03 mach with an 03 cobra eaton SC motor bone stock and I'm doing about 480... Good luck though. Should be interesting..

[95 GTS]

what compression? I assume very high and race gas to reach 450.

either way, if you are short of your goal, you have an amazing block and crank and can make up for any lack of power with more nitrous. say 200 or 250 eventually

[02silverstang]

well so far i have fr500 springs and valves and shm stage 3 cams 11.0 compresion long tube hooker headers catless x pipe ported intake and ported and 5 angle valve job on the heads shm said it is very fesible to get around that much might not be at the rwhp but at least 450 at the flywell i will keep every one informed as it gets closer .

[96greengt]

So who is it then saying you can make that power N/A, Kotzur or SHM ??
I still think even 450 at the fly is attainable with the mods you listed. How do you know you have that compression, if they ported the heads (combustion chamber wise), you'd actually drop some compression. Unless you changed your pistons, and even with stage 3 cams and texas heat, you'd still drop some to an extent...

[95 GTS]

explain to me how texas heat drops static compression.

If you can, get a hold of BOSS 330 about an intake for your setup. YOu will need at least 4.30s, anything less would be retarded.

[96greengt]

How about dynamic compression ??

update keeping the the teskid short block manley rods and je forged pistons melling bearings mmr oil pump with forged gears and just picked up 2003 cobra complete heads there going to get ported and cleaned up i also got a ported mach 1 intake hooker long tube headers now is 400 at the rear wheels possible nazman did it on a stock long block am pretty sure i can get get there .

[95 GTS]

very smart with the 03 stuff. However, I would still talk to boss about the intake. just porting the hell out of it, while gaining power will not have the best flow characteristics. His epoxied ported and reformed intake is siiiiick.

It might be the next step from the ported mach 1 intake.

That's where the 4v is beating you up Davis, the 03/04 Cobra/Mach heads are the best Ford ever made for the mod motor except the FRPP one. The 4v heads flow with some awesome results, and porting the upper intake only lets air flow better. Even switching the intake and exhaust cams with different ones versus all stock will yield more power.

400 is more of a reality with that set up, but after market cams, port work and the 4V tends to like it better, with a forged bottom end, 8k rpm is in reach. And Carlos does good work....

[02silverstang]

another update i was browsing throught karkraft and found a used set of fr500 heads complete that just need to be cleaned up and rebuilt for 1000 what do you guys think i know these outdo the 99 up cobra heads .

what are you talking about? Again you arent making sense, or you just cant comprehend my post.

I said the 03 stuff will be great. 98 cams in 03 stuff alone will be worth about a 30 hp gain.

I then suggested that he go with a chopped ported and epoxied intake by someone who knows what they are doing. Did you ever see the difference that some shaping work made versus just gotting the intake? have you seen a boss 330 lower?

Not true
The heads off the gt-500 and the gt supercar are

Then followed by the fr-500 ones

THEN the 03-04 cobra heads for power production in that order.

[96greengt]

Hence my posting that stated FRPP ones...
