We have a 1990 Ls itr and we want to go all motor on it. Some guy has a 1.7 vtech head that he says will work on our motor any ideas on that working or not? And any other info on building this motor would be great. Thanks

 

Bump any answers????

 

from what i've been told it should work but you will have to buy the vtec conversion i beleive im not sure though i have a b18b and im going to put a b16 head on it but i beleive the b18a bottom end would work wit the b18c head

 

Is the motor an ls or itr motor? Just wondering because you said you have an ls itr.

 

its an ls it camestock in the intgra's

 

yes it will work fine. From what I understand the head is identical to the b16.

 

It's a Ls, we will be using a B17 head on ours.

 

What they are forgetting to mention is that there is some other work that has to be done if you want it to last longer than an oil change or two.

If its a 90' LS, your about to try and ask a 20 year old block to now do more than it has ever done. You should bore/hone, and atleast get some ARP rod bolts to beef up the bottom end. Im not gunna jump and tell you that rods and pistons are a MUST, but it sure wouldn't hurt.
Once you've worked out the issues that are sure to come up within the rotating mass, your a golden eagle kit away from having the motor work done. Tackle the wiring, and your on your way.

i think you have to buy a vtech conversion to its like 180 dollars if that

 

What exactly is the vtech conversion you are talking about????

 

Again, reading the two links I posted for you will answer your questions.

 

My post is probably not necessary, but I'm bored right now, so here, follow along.
