PI swap question

[TBapp3]

if a PI guy was doing a head cam swap building the car in a NA direction and decided to run a NPI block for the bump in CR does the car have to be switched to the cap and rotor/plug wire route or would it still use the same set up/stuff to run the COP set up?!?

VERY interested in getting this figured out if any one can help clear the air for me I'd really appreciate it!!

Todd I'm pretty sure you still use all your cop's and harness. I know '96-'98 cars upgrade from the coil packs like on mine to cop's like your's so I don't see any problems there.

If you have any more questions, just ask.

You know I will Burt! Still waiting on my last few things to get here and contemplating running a NPI block for the bump in compression, I have one I was looming into for a good price but its kinda distant... Witch makes me think what did you do with your stock block?

My block is scrapped.

Your not going to gain to much with a bump to 10.5 cr using a NPI block. What you will lose is the ability to go FI in the future. Full bolt-on and cam'd 2V's will make ~300hp to the wheels. Using a NPI block might get you 5-10whp more at best.

I've seen some threads about piecing used Vortech kits together for about $1500 which is a pretty decent price. I think you'd be better off staying with a PI block. Loosing the ability to safely go FI for such a small gain doesn't seem worth it.

when did you get a sn95? lool

 

[TBapp3]

No sn95 here Jen just contemplating a NPI block for the bump in compression you get when doing a PI swap because I'm about to do a head cam swap any way...

Still debating though Burt my minds not made yet... I was just thinking how I could then get the heads cams and long tubes on the engine on a stand well mine is still I'm my car and drivable and then just have to tare mine out, drop in the new, and strap on the accessories...

I was also only looking at $100 for a complete still in car running w/ 100k mile 98gt engine but then realized it was 2 hours away.... So still debating it...

On the topic of later on, I'm always changing my mind but have been thinking sense I'll be running na cams why not spray it....who knows though after this the next modding spree will be a little while away and I think I'll be onto full suspension before more power any way but I'm always thinking...

I will read that link this evening I'm on my phone now and it s a PITA lol

I did not even consider spraying it. From what I've read nitrous loves higher compression. You also have to remember that you'd be on stock internals and limited to ~400whp. Spraying it will also create a hell of a shot of torque which stock rods don't like to much. I would think a 75-100 shot would be ok tho.

One other thing you'll have to watch out for if you go with a NPI block is piston to valve contact (PVC). There isn't much room for a big cam. This is the reason I never did cams in my car when I did my heads. I didn't want to chance any PVC. I just wanted to do a bolt on and go build that I didn't have to worry about.

Modular Head Shop (MHS) had some nice articles on their site running cams with a PI swapped NPI motors. I'll see if I can track them down later on today and post up some links for you.

BTW ... Where are you living now. I'll try to stop by some time and take you for a spin.

Haha funny I just saw you're "status" and said id love to take a spin!! I'm off Pattens mills rd up near the boars nest id love to meet up wherever and when ever would work for ya!! pm me!!

yes I was thinking a75 shot with the ability to still jump to a100 would be a fun time but I wasnt even aware of the pcv issue ... I do know that my tf "stage 1" na cams aren't the most aggressive out there but def another thing to look into!!

Some nitrous inspiration, I talked to this guy on fb actually, he has full suspension built rear and the 150 shot but is def pushing that engine to the limits!! Check his YouTube out some nice videos!

O yea and stock compression with stock block obviously...

She comes out of the hole hard. I don't think he's on stock suspension.
