What are the advantages if any to swapping a 94+ LS head on to the 90-93 B18 block?
Now I know nothing about running N2O on the B18. What should be done to protect the engine from damage? Of course N2O will damage the engine over a long course of time. I would run N2O after I/H/E, cams and cam gears. Would larger injectors be good?
i wouldn’t go any higher than 75 on stock internals. if you plan on using it often, or just as a safeguard for the future, forged internals (mainly rods, type r pistons would be plenty for 75-100, they’re pretty damn strong) would be a good idea. Eagle rods are on sale at importparts.com but i can’t look right now at the exact price because they don’t have good servers and can’t handle all their traffic. i think they go for a little under $400 for a set tho. if you want USDM pistons are on ebay being sold by a user named mcaz for a buy it now price of $220 with rings. i got some .25 overbored pistons from this person and i highly recommend. very good seller, very quick contact, and awesome service. not to mention hella fast shipping.
I’m highly consider droping .25 oversized JDM R pistions into the block to replace the stock ones. Not only because there old but because it will also raise my cr a bit. Therefore giving me more power.
agreed. i wouldn’t go much higher than 10.6 or MAYBE 10.7 with nitrous tho. too much compression with nitrous is just as bad (actually prolly worse in the long run) as with turbo. like i said i got the US R pistons just 'cause they were a little lower compression for the b16. i should be around 10.5-ish with my 100-shot direct port and that’s all the higher i’d recommend. with a smaller shot you MAY be able to get away with a higher compression but i wouldn’t risk it.
as far as ls head swaps go i really don’t know too much, ask mango i think he’s done it.
zex kits are great if you aren’t planning on being a heavy nitrous addict
importparts.com has eagle rods starting at (i think) $365, i know that it’s right around $400 a set for all b-series. my b16 rods are like $375-ish, dammit i wish importparts had better servers and i could actually get on right now. stupid place can’t handle all their traffic.
I believe the 94 and up ls head have a better flow,
I’m not 100% sure. But if you are interested in a set of eagle rods and srp 81.5mm with total seal rings, I let it go for $800.00 plus shipping.Btw they are brand new.
