5k With 3k Head

Featured Replies

hey, I'm new to the rolla Club thing, i have a suzuki LJ80 stockman with setup for corolla motor, I'm buying a 5k block minus head, i have a 3k head witch has been ported and shaved heaps, i was wondering if i should run solid lifters or hydraulic? i also have a stock aisan carby, if i jet that, will it be good enough?

Couple of things you should look into: Does your 5k have dished pistons, and how many cc are your 3k head combustion chambers. Suggest a bit of reseach.

if you have dished pistons and you use a 3K head it will result in lower compression. Taz Rx has a 3K big port head on his turbo 5K.

 

If you have flat top pistons, using a 3K head should raise compression. Apparantly flat top piston 5K's have the same head as 4K's. So putting on a 3K head will do the same as putting one on a 4K (higher comp).

 

The 5K should already have hydraulic lifters. 5K heads have non-adjustable rockers due to having hydaulic lifters. I assume with the right length push rod you may be able to run an adjustable set of rockers (not certain, just a thought)

"Columbus" pistons have 2 types of dish. One of which is identical to the factory dish.
