Ultimate Budget 2v Motor

Alright everyone I know there are plenty of threads in relations to this post but I am wanting the most updated responses with the direction I am going in. This isnt something I plan on doing right away but its information I feel is important before I start throwing more power at my car. My current setup is a completely stock 02 PI 2v longblock, boltons and a blower. Car is making right around 400rwhp. Plans are to go intercooled and start cranking the boost up but really not wanting to put much more stress on these stock internals and ruin this 2v block.

So here is my plan. I want to build a very budget oriented 2v. I have a good NPI shortblock sitting in the corner of my shop and was thinking of building it up or even my current PI block. My goal is to get the car up to 600hp down the road. Im just going to make a bullet point of questions below here....

• Will the cast romeo block be able to handle it or will I need to go teksid? Really dont want to source other blocks.
• Will the stock crank be able to handle the power? Heard they can take quite a bit of abuse.
• Will boss rods work in both the NPI or PI 2v's? I heard they are quite a cheap alternative and can handle some power.
• Whats the best budget friendly pistons to go with?

I guess me who has never built an engine before am missing quite a few things that will need to be purchased but that is why i posting these questions. Figured it would make more since to have a stout engine before I go throwing lethal pressure into a glass house 2v lol. Thanks for all the help.

 

Awesome, so what is the process to this then. Buy Boss Rods, some good pistons and have a machine shop clean my current block and reinstall? Would love to put an engine together myself.

 

Not even joking I will continue this thread for awhile then. I think I found my next project. Building an extreme budget 2v. Will either be intercooling and downsizing pulleys on my blower or go turbo. I think the first thing to be done is building the engine and converting the differential to a locker and all 31 spline.

 

I will start adding part#'s for reference...

Boss Connecting Rods = CR3Z6200B

 

That would be great, if you have a good link to bearing part #'s that will help aswell. I think I am going to be building up the NPI block and throwing on a set of PI heads & Cams

 

Great info, Yeah looks like the pistons will be the high portion price of all of this. Unless I kind find a good conditioned termi set of pistons.

 

So I began tearing down the old NPI spare block I have, all the internals looked to be in great shape for 140+k on the engine. Main bearing and rod bearings looked great with very minimal scaring. Bores are in great shape too just need to clean the crap out of the block.

So here is a list of parts with pricing I have. Let me know of any major things you see I missed. I still dont know what I am doing for pistons but am budgeting about $650 for whatever it is I go with it will need to be for a factory bore npi 4.6 . Also what thickness HG should I go with? Setup will be a NPI block with PI heads and boost.

Item Price
Boss Rods $180
Main Studs $115
Head Steads $280
Main Bearings $115
Rod Bearings $110
Cometic HG $118
Pistons $650

 

Im not 100% sure dont want too much compression but enough for that happy medium.

Thanks yes I kind of added that on, I was looking over on modmaxracing at their product line. Couldnt find much info on other aftermarket pistons. It was around 650 or so with their ring set for the forged piston assembly. No idea of their quality just a short search.
