ok, my gxl is broken down. ive been looking for a DECENT t2 for a long time, because i want POWER. but i was thinking, since im going into auto-x. i should try and build up a a pretty good NA. my question is, would it be possible to get 250hp and sub 14 second 1/4 runs out of an s4 NA, if so, tell me what i should get, money's not an issue

 

You can get 250hp from an N/a. But its only done through radical porting and extreme modifications that make it unstreetable due to lack of low end and extreme noise. You'd likely need a bridge port and a full race exhaust.(race=teh loud!) The highest street port dyno I have yet to see is 170ish hp. Search for Icemarks thread on going back to N/a from turbo and you will find his dyno sheet.

 

how much would lightened rotors help?

 

It won't be cheap or easy. I'm hoping for low 14s after I get my vert wheels and my SAFC tuned. Plus your car will be crazy loud. If money isn't an issue, buy a TII.

 

ok, here is what im thinking so far as of mods.
-rebuild with~ 3mm apex seals, fd corner seals, cryogenic treatment
-half or mild bridge port
-tb mod
-mustang mass airflow sensor
-rb headers with 3 1/2" straight through pipes and 1 big *** muffler
-t2 fuel pump with 550cc secondaries
-underdrive pulleys
-removing all un necasary parts (ac, ps, other junk)
-light flywheel, good clutch
what am i forgeting

 

Strip the mother!

 

Stock fuel set-up ain't gonna work. I am not too keen on a half bridge either. A full bridge, RB carb set-up and full RB exhaust will get you where you want and might be the cheapest route too.

 

would the dual 50mm throttle bodies be a good thing, i forget who their made by

 

with 250whp, you'll be running faster than mid 14s

 

You're not goin to get 250hp out of an auto-x'able N/A. You need a peripheral port, with a powerband between 8-12,000rpms. Strictly a drag or oval track car. Definatly NOT for the street.

Or

Buy my turbo gxl! Just put it up for sale- 2800 US.
Cheap! Easily 250hp, untuned.

Mods are in my sig

 

I don't believe anybody has got the Mustang MAF to work yet.

 

oh, i searched icemark and saw a thread, how to build a beefy na, and he said he was puttin a mustang maf in

 

rxseven is right.. a big street port on a 13b using 4 port t2 side housings , a holley racing beat intake , 650 jetted carb, wit regulator and pump.. would help... maybe even half bridge on a holley setup would definetly get u in the 13's.. that was the case for my 84 gsl...

 

would it be streetable at all with the t2 housings and a carb set up

 

You will get pretty bad gas mileage if that matters. It will probably be pretty damn loud aswell.

 

Yeah, it should be streetable unless you go for some ridiculously radical port job

 

thanks for all the help, im ordering my new engine hopefully this week. one last question before i start the project, do the guys a fc3s.org do bridge porting, at their website it says they do stage 1 and stage 2 street ports for the na fc. and would this be a good idea for my application, which is auto cross and drag racing and street driving. http://www.tweakit.net/shop/product_...roducts_id=117

 

oh yeah, and would i have to get an ems. or is there a way around it, or would it just be a good idea anyways
