[PlATiuM]

[BelGarion]

cool ross

yer make sure its a bolt on kit designed for 33 ross

dont make the mistake i made

[BelGarion]

means all thats left to be done is the tuning!

sweeeeet

[BelGarion]

oh well ive taken a large chunk outta the ricemans lead

i guess ill have to resume my efforts another time

[rb25]

its off another rb25 and ive seen it run on that car so its all good (i think). will get gavins advice i think. not even sure exactly what turbo it is. looks a bit smaller than yours james, it has a T28 flange.

[PlATiuM]

tuning hehe see what else pops up :S

my mates vn v8 is back in at driftking i was told getting more done :|

[BelGarion]

hrmmm t28 flange is more like what sr20s have on them, but then again i think you can get pretty large turbos with t28 flanges

mines t3 flange, its a gt30

[BelGarion]

if its been on another rb25 then you know its gonna fit ect

mine was a tight squeeze

A while back we saw a block failure at the ~700rwhp level on Chemvolt's engine. Here is another failure from toymanf's engine. This engine was doing it's first competitive 1/4 mile run.

Toymanf is not sure how much power he was making on the run, but the dyno he was on while getting the engine set up gave 540rwhp on turbo only (all subsequent runs were done with the tires spinning on the dyno) and the 1/4 mile run on which the engine failed was running that plus a 200 shot of nitrous.

The tune was conservative and you can see that there are no signs of detonation on the piston or cylinder walls. EGT temps were fine. AFRs were in the 11s. Fuel was C16.

The block was a seasoned stock block, bored 40 over. A 1.6mm HKS headgasket held down with ARP studs torqued to 65ft/lbs. It appears that the corner of the block around the #1 cylinder was unable to hold the lifting force that the head was putting on it.

There was at least another 100rwhp left untapped in this engine, but it is unclear at this point if the 3s block is capable of holding that much power over the 1/4 mile.

Any thoughts on how to contain +700rwhp power levels and keep the block intact? Sleeves would not have helped here. I've heard of using 1/2" studs but that is going to require a lot of work and I'm not sure if there is enough material in the block to make that work. Would the 5s block more reliably accept this much power and more?
