Hope this helps some. I am thinking of adding LS6 stg 1.0 PRC heads.

Thanks again guys!

First off great looking car. Always liked swapped FCs. I don't know much about that cam but I'm kind of surprised to see it start falling off before you even hit 6000 RPMs.

0Larry @ AMS

very nicely done

I do agree it appears to fall off early and it appears the A/F was 12.3 which is on the fat side.

FC3S Murray

Thanks guys! Appreciate the kind words.

In regards to the cam; I thought the same thing about it falling too early BUT when my tuner pulled fuel I actually lost about 6-7 hp and trq. Motor liked the fuel fat. This was on crap 91 octane too.

That's what I'm talkin' about.

Will be interesting to see how that LS7 clutch holds up for you.
I'm sure it'll be fine on the street.
Any plans to run her at the track?

Yeah she is pretty light.....I have traction issues

I love the LS7 clutch with the flywheel. It is very streetable and no slipping yet...just still getting used to the T-56 and its super close gate pattern.

I do plan on running in the Porsche club of america late this August. Other then that maybe a few SCCA runs and a stop at the 1/4mile when I get my Nitto NT05R's on the back....the Falken FK-452's just are not cutting it in 255/40ZR17.

Right now I am just having to re-learn the cars behavior since it is night and day compared to my old rotary turbo set up. Once I get the suspension dialed in next season will be full time........pocket book permitting(not to mention the wifes patience)

Beautiful car/swap. 2700lbs and 425rwhp makes for a whole lot of fun!

cam only ls1 with only a 228...good numbers!

FC3S Murray

Thank you!

Yeah I have been told my numbers are pretty strong given my little mods. Last production year LS1's must be tough

slowtealz28

That thing is going to FLY. Nice car!

mcm95403

Beautiful car and you've obviosly put a HUGE amount of work into it - well done!

FC3S Murray

Thanks slowtealz28 & mcm95403. The car has been a 7 year project. Everything on the car was done by me. I went through many rotaries and finally got fed up last May when my heavly modded rotary gave out. This LS swap took me about a year. I am addicted to torque now lol.

Thats one hell of a shoe horn you used

madmatt9471

Thanks,Matt

WOW gorgious FC man! Must be a rocket ship at 2700 lbs! IM sure that thing could snap off some mid 11s

Nice TurboII very clean install, your definitely gonna need some sticky tires!

FAST Intake will definitely help with the upper RPM issues.... I had and LS7 clutch in my car for 4 years with no issues..... other than its not the best drag clutch but its good on the street and feels like and OEM unit good swap car looks awesome and thanks for posting

FC3S Murray

Thank you!

The look on peoples faces is priceless when I give it full throttle....makes me smile big every time

Same with your Vette


Appreciate it man! Yeah it is fun, I weigh about 190 so me in it @ 2907lbs is still much fun!

The dyno said in the "Perfect World" it should run 11.4....lol......I have a lot to work on but when I do hit the 1/4 mile I will post up my timeslips here too.


Nice to see you know your Mazdas Maybe down the road when I overhaul the motor I will make it stay true to being a "turbo"..hint hint


You are welcome for the post. Thanks for having me.

So I have read that the FAST intake compared to the LS6 intake is really uneccessary unless you plan on going forced induction. The $800 price tag makes the little hp/trq gains seem a bit to pricey. Is this true?

I am glad to hear the LS7 clutch is a good deal...it was hard to throw that much $$ at a OEM clutch kit.

LightFighter_GXP

i upgraded to a monster clutch now and I'm really liking it. FAST INTAKE on a H/C car will pay dividends... on a stock motor not so much

I would be really curious about this myself. Down the road (probably the same number of years it took you to build this -- the better part of a decade, lol) I would like to go the direction of a centrifugal supercharger.
