i have been reading what everyone was telling "blight" about 300hp with his turbo.......... now, what can you all tell me about N/A's??? i want that kind of power without the turbo for now (300rwhp)! i can't figure out my problem with my motor and it is just getting worse, so i am going to pull the motor and tear it down! i will fix it peice by peice if i have to! i plan on doing the porting myself also! i know how to port heads and so on with a piston motor, so this can't be that much more difficult! i have been reading up alot about porting these motors and i know where to get the templates from! eventually i will convert it to a big ass turbo, but for now i am going to keep it easy!

If you want 300rwhp, you are better off getting an already modded turbo II, or converting the N/A to a TII. Not saying you CAN'T turbo a six port block, just saying it's more difficult and complex than BUYING an already modded TII.

you say it is alot of fun....... which tells me you have or know someone that has done it! what do i need to do to the N/A to get that power out of it??? i have seen that they make turbo conversion kits for my motor, granted it is alot of work and fun, not to mention alot of beer, but it can be done! i know that it would be hard because of the compression of my motor, but i am willy to try it! first i want to punch some power with no turbo and then when i get used to that much power with that little car..... then i will put the turbo on it and really have some fun! give me some ideas if you can please! i know about porting and fuel to air and so on, but is there anything more special about these cars??? thanks!

PP or nitrous will be the only way get that power. Have fun!

rowtareh 02-02-2007 12:50 PM

It has nothing to with the compression. A tuner (good one) can overcome the compression numbers of the N/A blocks. It's the six port design. The 5th and 6th ports activate at a certain rpm. When you are that rpm, that's usually when a turbo is right in the middle of spooling. So you have 5th and 6th ports activating, and you have a turbo spooling forcing MORE air into the motor.



I don't know who has done this conversion on this forum, but there are some on the other forums who have done it and have a good running car, but they would have been better of with a TII or a complete swap out.



And yeah, the only way to achieve anywhere close to 300rwhp would be a periphreal ported engine, or some N20. But you step into those boundaries, especially the p-ported engine, you are running into BIG bucks. Unless you do it yourself.



Good luck.

also it will probly be unstreetable with those ports and turboing an n/a will probly cost alot more than a tII swap but i could be wrong if certain things are applied

Most p-ports are unstreetable. I think mike(j9) was saying that his will be more streetable than a bridgeport.

I street drive my p-port pretty regularly, yeah its loud, and back pressure totally kills power on a p-port..

They make quite a bit of low end power, way more than a stock n/a. They like to be throttle loaded, so you have to change your driving style a bit. Mine makes a peak right now or 206 rwhp as measure on a mustang dyno in street trim. In my light base fc it makes for a fun ride. right at around 4000, it starts to pull harder than my TII did when it was a BPU s4 turbo car and it screams all the way to 9500 easily...

The cool part is with the turbo transmission I pass 60 miles an hour at the top end of 2nd and its lag free so it makes for some pretty outrageous zero-sixty times if those float your boat. You have to drive it like you stole it to truly enjoy it, and kiss listening to the stereo goodbye as well..... https://www.nopistons.com/forums/pub...O_DIR#>/v2.gif

Maxt, what does your's idle at though? That's the biggest thing that turns people off about them. Never heard a p-port at idle though. Heard plenty of b-ports though.
