few engine mods

[98warrior]

well in the near future im gona have my uncle to install a web cam, kibblewhite valve spring kit and maybe a higher compression wiseco piston, but my question is should i buy the "all around cam" or the "race cam." my engine is completely stock. oh and whats the name of the tool needed to pull the valve springs?

Definately go with the race profile cam, when you lay on the throttle it doesn't waste any time and pulls like hell all the way to the top!!! To make a valve spring compressor just cut about 2" off of a 3/4" piece of steel pipe and jb weld or actually weld it to a large c clamp (on the rod, not the actual 'c' part). You'll want to cut almost half of the tube off the long way (so it looks like a half pipe, but not quite that much cut off) so you can reach in with pliers and install/remove the keepers. Don't go with the wiseco piston either, go with the JE and bump it up to almost 11 to 1 compression, you'll get a bit more power that way. You can still run on pump gas also, so don't worry about that. That combination runs great, you'll love the power increase.

Id agree ^ get a JE or CP piston.

alright thanks you guys, oh and with the 11 to 1 could i run 93 octane or have to run 98? oh and one more question is re-jetting required? im thinking that it is, but im not sure.

 

[boxhead]

You can run premium pump gas or possibly mid grade, somewhere between 89 and 93 octane. 98 octane would be enough to run nos on a warrior with 10.75 to 1 compression, lol. Yes you'll need to rejet, you're gonna need more fuel in there.

hey boxhead if you bump up the comp. do you really have to rejet or can you just get away with a higher octane. you said you need more fuel but if you are just putting a higher comp. piston in then there is less room in the chamber.

 

[98warrior]

no im also adding a cam and valve spring kit.

 

[87warrior78]

i know that is what you said in your first post but i was asking boxhead basicly if you just add a higher comp. piston do you have to rejet.

 

[98warrior]

oh sorry got a little confused.

 

[boxhead]

If just the compression you might not have to, but you also might have to. Whenever I've done it I've always bored it over and done other mods so I can't say for sure.
