Soooooo while attempting to install my icebox i decided it was easier to just take off the the intake manifold to get the stupid little hose on right. while putting it all back together, i think i might have damaged a gasket so im getting a new one. im thinking though, while i wait for this all to come in should i have my stuff port and polished. i have NOOOO idea what PNP is or what it does exactly. which parts would be ported and polished? how much would it cost?

as of right now i have the IM and TB off the car but they are connected together. during a PNP do they need to be taken apart?

if somebody could just explain the whole process to me i think that would be best. i appreciate all the help

 

instead of buying the stock gaskets should i just get the Thermoblok ones? i guess that would make more sense

 

i wanna know toooo!

 

PNP is basicaly enlarging and smoothing out the intake and exhaust tracks for better airflow to get better hp. Its best to have a pro that knows what they are doing on either a machince or by hand enlarging and smoothing out the intake and exhaust tracks. And also if they have or will flow bench it for best results. There are many pro's, better air flow and an increase in HP especially on blown applications. The con's are a novice can do too much and if you don't "flow bench it" you may not do much good. It can get complicated. Honestly, your wasting your time with this engine, you may gain 10hp, but the cost will be about $1500 give or take. Its very popular in bigger engines where it makes more of a difference, and on blown apps you can get like 50hp sometimes.

 

if you have a dremel set and the proper attachments and don't do too much can't a beginner do this as long as they are careful? I wanted to do this in the springtime as a little project. I figured it would only take a few hours at best.

 

god deyummmmm, ill scratch that off my list very fast. its def worthless. thanks for the help

 

just install the damn IceBox!

 

its not worthless, just not a high reward for the $$ on say an acura engine like this. you could probably do it with a dremel, i wouldn't recommend it, but give it a shot and let us know. just remember, you are sanding down metal/aluminum, an air tool would be better.

 

i know but i have some very abrasive bits that can cut metal and some fine ones to polish it. Maybe I won't do it, but it is tempting!

 

I seem to recall a Type-S owner porting and polishing his intake manifold, and on the subsequent dyno run, it actually made less power.

Just something to chew on.



By the way, the spacer kit still uses the stock gasket, so you will need a new one regardless.

 

screw it then, less power? I am out, I will focus on some other project then.

 

well, don't forget that after its done you need to have it tuned, more air = needing more fuel.

 

I did mine when i was bored 1 day. This kinda gives you a idea what p&p is





And can i add Why did you think it would be easier to take off the IM than to take the time to figure out how to remove teh hose

 

well, i couldnt get my pliers on the hose right. it was stuck on soo tight i just couldnt get the thing off right. so i got tired and just took the whole thing apart.

so, the thermoblok spacers still require using the stock one as well?

 

Polishing is not the objective when it comes to the intake portion. If someone wants to increase velocity, or better yet, atomization, a staggered or even abrasive finish has been tested and shows that it makes more power in most cases. Excite the air, so to say, by creating these rifts. The only time you should polish anything is on the exhaust ports. I know you guys are talking about the intake, but in my xperience with several chevy small block single plane intakes, the "rift" effect made HUGE gains in the top end performance. I may still have my dyno sheets from stock(well when I had the original intake, not exactly stock) and then when I had the rifts etched in and flowbenched. @ 6600 rpm it made a 37hp difference at the wheels on 93 octane (sunoco) all the while at 14lbs. of vacuum. Rex Hutchison techs did the work.

 

porting is a reasonable move, but don't open em up too much, otherwise the velocity to your heads greatly decreases, thus less air, less fuel, less power. This is basically done when you want top-end power. Ever notice longer intake tube kits get you more torque?

 

did the person doing the dyno wait til the ECU was reset and got used to the smoother flow? because when i did it, i gained immediately, and after each mile, i could tell i was gaining more. plus it definitly did yield more power. i dont know if this is something with the Type-S, but my 99TL definitly performed much better after port and polishing it myself.

and yes, i took basic dremel tools and smoothened out the holes myself. it wasnt too hard, i have DIY on it somewhere on these forums. its definitly worth doing and i would NEVER pay 1500 for something i would do myslf. but the 10hp gain sounds about right.

 

here's pics from my DIY









took me about 2-3 hours. not too long at all

 

here is another link to some P&P pics off the ROUSH board

hey rick what's happening? merry christmas!

anyway, back to the topic at hand...did you gasketmatch or portmatch the intake ports where the head meets the intake manifold? you should really consider doing that to see maximum gains. it's easy enough to do, just pack the opening with a rag and put some playdough in it to seal it off. after you're done grinding just vacuum up the shavings and remove the packing. voila. i did this to my taurus SHO (prior to selling it) and definitely saw a power increase.

on our cars (as mentioned) the P&P has the chance to be worthless, but gasket matching is quite benficial.

SSTS

 

i dont mean to pick on you... but the part where you say "i gained immediately and after each mile i could tell i was gaining more" cracks me up

dude... that's not a 50hp mod you did... it prolly doesnt even give enough HP (if any) to feel it... unless the ports were all clogged up, there's no way you were gonna feel it the way you're describing it.
