Hi all I'm new to this forum what mods do you recommend for a 20v motor?

Aww god here it comes again.

 

Firstly for our benefit, what kind of budget do you have? Blacktop, Silvertop 20v??

 

The first mods you would want to do to a 20 valve is not so mutch the motor itself but other bits around it.

Firstly get an exhaust done, something like 2.5 inch will do fine, with a high flow cat and sports muffler (sound sooooo mutch better than cannons).

This would cost you roughly $600, maybe more maybe less depending where you get it done. If you can not afford something like this forget modding the 20v

and the best you can do is just keep the motor fresh and treat it good.

 

When talking about modding an engine, especially when it is an N/A motor it is all about camshafts. For 20 valve motors they are not cheap (average prive about $800 a set)

and then you have to install them. Then you would think about increasing the compression ratio as well as balancing the crank and getting forged conrods to handle regular high rpm hits.

High comp pistons = $600

Engine balance = $200 - $500 (guesstimate, if you pull the motor apart yourself and give hime the required parts it would be the cheaper)

Someone might be able to confirm a price on balancing a 20 valve

Rods = $??? Haven't personally even seen these

Lightened flywheel = $??? I got mine for free with my 20v when I bought it.

 

As you can see it is going to cost a bundle, but it all depends on what you want from the motor.

As alot of people say, just get the thing running A1 and then think about going further.

I say trumpets and an aftermarket ECU
