about how much HP gain do you get from doing the hybrid vs stock 22r ?

i didnt have access to a dyno but i can tell you, i broke a new speedo cable

i would say 20 hp give or take,

probably more

Not much really, maybe in the 10hp range. You'll doubtfully feel it, you'll just notice it'll pull longer and may find a little more power pulling hills. And glen, you know hp won't break a speedo cable

Why'd you go .010 and .010 on intake and exhaust?

bhigdon101 · « **Reply #64 on:** Jan 11, 2009, 07:36:55 AM »

you need a 20R head and intake, also run the 20R, or very early 22r dual row timing chain

Helps to find a 20r head with a fuel pump boss if running gas. Not all had them.

ok head and intake... easy to find...

how about a cam and vales

i got a little lost in that part of this thread....

looked at lce and there cams were like 399.00

so what is the best way to set this up from ground zero..

bare head no cam, nothing.. what do i need to do...
even part number's will help .....

i want to do it right the first time...
thanks guy's... i went to pirate and searched could not find nothing on there either...

ive never seen one that didnt have the fuel pump block off plate. i suppose its possible but 79 was the only year i know of that had electric pumps

i HAVE seen the early 20R's that didnt have power steering bolt holes

thats all the off road place had at the time!!

what should i get

kneedownnate · « **Reply #75 on:** Jan 13, 2009, 08:29:53 PM »

All they had

you mean feeler gauges? It won't be too bad to run the intake valves that loose, they'll just be really loud and clacky, but you can seriously flop things up running the valves too tight, and you're way too tight since the exhaust valves are supposed to be at .012! And fyi, if you're buying a set of feeler gauges you'll wanna get an angled set

There definately needs to be a tech write-up on the 20R/22R. There is alot of info and alot of opinion and it is all scattered out. It's hard to tell what is tech, what is opinin, and what the actual process is... It would be awesome to see it all in one tech thread.

can you bolt a 80 model 20r head on a 93 late model engine?

You need an earlier 22R block with the dome type pistons to get the hybrid performance. If you read the whole thread... I'm sure it answers that question...
