more reliable SR or CA?

If you want a motor with beefed-up internals, you might want to start shopping now like getting pistons made to whatever spec possible or depending on how much power you're trying make, I can see you making god power on an otherwise internally stock CA. It can be done and there's no need to buy forged pistons and steel rods to make up to around 400whp reliably out of an internally stock CA because it's all in the tuning and fuel system. If need be though, if you can scarf a set of 264 duration cams with say about an 8-9mm lift then kudos to you. I say buy the motor and transmission and go from there.

I was thinking of internals or just maybe a good set of pistons with the stock rods.

I want the head to have everything (cams, cam gears, solid lifters, etc)

I do know I want the motor rebuilt with fresh bearings.

So yea, ill just go ahead and get the motor and transmission. I'll be able to get it a lot sooner too

Have you rebuild it and add the parts, if you have time. Ill drive down there and do the swap.

Sound like a good plan?

Awsome, now I just gotta get this CA back in soon, then start on that next CA project:D

Yea thats why I was wondering about the ARP ones. I just want to get atleast 300 whp from this motor.

Paul (Movingviolation240) said the stock bolts should be good for that. Stock headgasket should be good for that also.

Most likely ill get an aftermarket headgasket with stock headbolts.

What should I look for on the pistons? Just anything out of the ordinary?

The car still ran perfect right up to the day I took the motor back out. The problem was coolant leaking out near the turbo. Only reason I took the motor out was because that car is my daily driver and I have to use it to go to work and I was too broke to fix it

Oh and the turbo had finally quit.

Does the ca18det have torque to yield headbolts ?Is this in the service manual, or u speaking from experience ?for stock head gasket ?Did u ever get an ARP solution for this ?

At 300whp, the stock headgasket and headbolts will be up for the task whilst remaining reliable.Quote »Does the ca18det have torque to yield headbolts ?[/quote] Yes! The manual should cover this as well. Depending on what type of gasket you purchase, you may be able to eliminate some of the torquing steps required by the manual. I used a stock beck/arnley unit which had the unique perma-torque feature which allowed me to eliminate all the requirements of the chilton manual I used. And that headgasket was allowing me to visit 20+psi under highspeed highway loads. As long as you use a fresh set of bolts, you will be just fine. If you use the stock bolts again, more than likely they have stretched a bit and will cause you to blow another gasket and this is from experience.

thanks. good info. I'll try the beck Arnley head gasket with new bolts.Did u torque em once and leave 'em ? Remember the ft-lbs ?I'll tryout some ACL rod bearings too, in my 3rd motor.

I must get my hand on a nissan service manual. I'm on dialup and a buddy downloaded it from the uk site, but had a buch of critical pages left outta the engine section... just my luck

Quote »Did u torque em once and leave 'em ? Remember the ft-lbs ?[/quote] Actually, I gave them a 2 step torque sequence which only involved the initial fitment of the bolts and final in-sequence tightening. My final ft./lbs was 80ft/lbs and that engine is now serving someone else just fine.
