Hey guys I am in the process of rebuilding my block and since I am not able to do my own work the cost of labor is high. I want to sleeve my block but due cost it is not possible at this time, although I bought and replaced everything else.....wiseco forged pistons 9:1 cr, eagle rods, cosmetic headgsket, arp main and head studs, oem bearings, timing belt, oil pump, water pump, etc..... I have a b18c1 with 60k and is a 98.

My question is would my block last just as a sleeved block would if I only intend to run 8psi daily and then maybe 15psi at track visits ( not often). My turbo install and everything else was done by JE Imports Performance who are also rebuilding my block. I was thinking about possibly sleeving the block tax time but if can get by without sleeves I could use the cash on an LSD or something?
Would it be worth it to sleeve the block tax time even though I don't run the ---- out of my car which is my daily driver? Are there any guys out there running non sleeved block for periods of 2 years or greater? Any thoughts? Thanks

 

theres plenty of people running unsleaved blocks, but if u want a block to be stronger and handle more u can do the moroso block filler with your forged internals, its cheap and works, beau on here ran like 30-33psi on a big t4 or somthin with a stock sleved b16 with forged internals and made 467whp, so ya, and theres other people on here with stock gsr motors, but somtimes with b16 heads to lowe the cp and there running 15-16psi perfectly tuned on a sc61. so idk its up to u, but for 15psi on what turbo? it dosent seem like u need to spend th emoney to get it sleved. just my opinion

 

In the recent issue of D-Sport Mag they ran 18 psi on a completely stock B16, everything held until a ringland let loose on a piston. You replaced the pistons so you should be fine at 15 on the track IF you tune it correctly.

 

It's all about the tuning on non sleeved blocks. I made big power on a stock sleeved block, but only on the dyno and at the race track. At your boost level you shouldn't have a problem with a stock block.

 

Just do me a favor and don't run a blockguard.

 

no sleeving, no block guard, no block posting, no block filler, period. just good tuning. plenty of people are making 500-650whp on stock bottom ends besides rods/pistons.

 

on stock sleeves id go 9.1 comp
when ur making mucho power it will be very hard to tune high comp

I've been very very busy lately, but I think some more free time is about to come my way(i.e. another job)
