Make a Cobra Engine from a GT

suprmnhmb · July 20th, 2006, 06:16 PM

Is it possible to make my 03 GT engine to a Cobra engine? How can i do that, and what parts might i have to change on the engine?

drgnracin72 · July 20th, 2006, 06:24 PM

yeah the blocks are almost the same. youl have to have a few things drilled and tapped into the block becuase the 4v heads have a few other timing components than the 2v does. but yeah its possible to put the 4v heads on them!!!

mdvaldosta · July 20th, 2006, 06:44 PM

It's not cost effective though, heads... intake... accessories... etc. Really the best way is to buy a Cobra engine and swap it.

drgnracin72 · July 20th, 2006, 07:31 PM

yeah what he said. youll be able to make a whole lot more power though with the 4v hjeads if you went FI

either way....it would be badass

WilltheThrill · January 18th, 2007, 07:05 PM

the cobra blocks are cast iron too, so it would surely be wiser to just get a cobra engine

White99stang · January 18th, 2007, 07:21 PM

actually only the 03/04 blocks are cast iron, the 99/01 are aluminum

U simple need a top end swap. you can probable find one for about $1200-$3000 for the pre 03 cobras' top ends. I've actually seen a complete kit 98 cobra top end conversion on ebay for $1375 shipped.

That may be true finding them for that cheap, but the 96-98 cobra's used the "B" series heads which are basically thought of like the non-pi 2V heads,... the best thing they make for are paper weights. The justification would not be worth it to spend all that money on the B-head stuff and gain not enough over the non-pi/pi than to spend the little extra and buy the C-head stuff on the newer cobra's and gain alot

StangAddiction · January 18th, 2007, 08:05 PM

i undestand what your saying, but they still have more potential than the 2v. Either way.

oh my bad, I thought the 99-01 cobras had the cast iron block too

DSEZ · January 18th, 2007, 10:09 PM

yeah i believe they were alluminum...i saw a 99 cobra with a crack'd block the other day i dont know how the guy did it but i about shit myself.

Kornut · January 18th, 2007, 10:19 PM

^^ Yeah, I also wonder what he did. It is a VERY rare occasion when the aluminum block cracks.

and just for clarification....

96-98 cobras = teskid aluminum block
99-01 cobras = wep (or wap) aluminum block
03-04 cobras = cast iron

WilltheThrill · January 19th, 2007, 03:23 AM

oh ok

James_02gt · February 25th, 2007, 09:53 PM

So if it's more cost effective to just buy a Cobra engine and drop it in, what exactly would a person need to do to make it actually run and work in a '02 gt, what other (mods) would need to be considered? Where can you even get a cobra engine from (03-04)?

James_02gt · February 25th, 2007, 10:35 PM

Can you only get the Cobra engines used? Other than ebay where else. What about dropping it in, what else would it take.
