no matter what rods you use, replace the OEM ones with ARP rod bolts

 

i will be using arp bolts and head studs :D

i will be running a chipped ecu from mtber or kenji before i get it tuned im a bit worried about driving it around, but will i be ok ? or will i ahve too much comp?

will i be ok with piston to valve clearence

 

might have to clay the motor when u put it together just to make sure you get good piston/valve clearance

 

what is meant by clay

 

Clay to mesure the valve clearence. Make sure you dont slap a piston into a valve and skew everything up.

Couple of things i would checkout first
Dont use ctr pistons.
I dont think itr rods fit, 87 vs 89 But im not sure ask around.


Compression Calculators are wrong on the ctrs. in a LS block and a b16 head its 12.8:1 in a GSR head its higher. Bad for the street.

Use P30 Pistons 11.5:1 flat dome and arent as heavy

use Ls rods if your staying NA.

Vtec water and oilpump and a GSR timing belt along with the ARP's and your golden.

Searh reliable LS/VTEC

 

Yeah what head are you using? I'd be willing to bet you're overcamming also.

 

i will be running TODA c's and a b16a head with p+p, gas flowed.

 

Overcammed.

 

what about gsr pistons as compared to p30 pistons

 

the dude that is building the motor for me said they would be fine.

when you say over cammed are my Cams too agrssive? or oposite?

 

Too aggressive
