I recently just cracked one of my sleeves on my stock jdm b16 bottom end. One of my friends has a stock ls block thats been laying around. Its completely stock just has arp rod bolts n thats it. Will it be fine if i just slap on the b16 head with the ls vtec kit n all that n it should be fine? Im only aiming for 300+. My jdm b16 only lasted like 2 weeks so i never made it to the dyno was only street tuned. Was just wondering if it should be fine running the stock block n boosting it. Would it be better than just the b16?

the reason u cracked a sleeve is because u drove it without being tuned. if u do the same thing to the new block your gonna end up with another cracked sleeve. boosting a stock block is fine but u MUST HAVE A GOOD TUNE.

X2 you need to get it tuned right away. How many psi were you pushing with what turbo? I'd throw some arp rod bolts on that ls block before you start boosting

Whiterice-gsr

its already got arp rod bolts lol.

Lol could've swore it said arp head studs but guess not. In that case you should use arp head studs to.

x2 lol, u know what though i was gonna do the bolts and head studs and just leave it at that bu man seriously youve already got the head and pan off why not just do the rods and pistons all in one shot and be done with it. this is what im doing as soon as i finish my tranny.

I wouldn't use the LS pistons, not really enough of a vavle relief for when the bigger lobe's kick in at higher rpm's.

The reason i cracked a sleeve was because of my MBC. I was tuned. My car spiked for some reason n than blew. Im getting arp head studs for sure. Im just gonna run this block until i rebuild my b16. I just wanna make sure the pistons n rods n all that can handle 300whp. For like 6 months until i slowly finish my block.

If i build the motor i wanna go all out by getting it sleeved n so on. I just want to run this block till im done with all that.

i was running 8.8psi on the b16 but spiked to 20... Its a precision 60trim .60ar .48 hot.

an 8 lb spring would do fine no need for an mbc but u said "street tuned" and u never made it to the dyno how exactly did u tune it.

JDMCIVIC919

Tuned on crome. The reason i put a mbc on was to reach my power goal if i had to up the boost when i dynoed it

DirtyDA9

Could have been the wastegate that malfunctioned... Just be careful when you get the new setup together, that it wasn't that.

An ls bottom end stock can handle 300hp no problem. I say use it, and build another on the side.

But remember to use VTEC water and oil pumps and timing belt.

Ok im just going to swap that stuff over from my b16 block.

Whiterice-gsr

so were u looking at the gauge when it spiked or did it just take off then pop, im asking cuz ive never experienced a boost spike before im kinda curious.

JDMCIVIC919

I was just watching the road cuz did a 4th gear pull. Just pulled really hard n than boom

Dumb question but I'm about a do a lsvtec too and also thinking about boost got b18b1 stock rods gsr pistons no wall support gsr head ARP rod bolts and head studs wanna run at least ten psi on a 60. /.63 eBay turbo for now any suggestions? And a chip with my set up on 10psi base tune I guess I'm new to the whole turbo seen just trynna do my hw

If it was tuned and it still spiked like that, i'd be looking for another tuner. Tuning in a simple boost cut would have avoided that issue...

Edit: Just realized this thread is hella old

Schister66

The Forced Induction FAQ is a good starting point.


Another suggestion - ditch the Ebay turbo and get something reliable

lmfao Schister66 - this is one of those moments you need the easy button lol
