Default Need opinions....Engine/twinturbo ?s

Ok so here it goes. I have just ordered an SLP short block 402. I got heads and intake manifold on the way. 239/24? cam(dont remember exactly)....I got a FAST 90mm intake manifold and TB on the way. STS remote twin turbo set up with upgraded turbos and some extra stuff....

Should I run a 100 shot of direct port N20??? I have talked to a few people and they say yes and some say no. what do yall think?

Absofreakinglutely.... sounds great, You will love the nitrous.... although, I have heard that those shortblocks (SLP 402's) were not actually built with forged pistons, they also dont include the needed ls1 or ls6 to ls2 parts like scdpc does.... i would double check on that or cancel that order and order from scdpc or tsp or one of the other reputable engine builders, That is what I have been told from other sho went that road and their motors blew up, one in the first two weeks.... just be careful

Yeah.... I was kinda just trying to steer him away from that short block at all. That is a good point though.... it may not handle that if you keep the slp 402, So like I said be very carefull

check out ecs for the alky system. while your check out their fuel and paxton systems as well. top notch!! the last forged 347 they did made 730+ rwhp w/ 13 ibs of boost and stock heads.

I’d skip the nitrous and go with the alky injection.

That cam sounds way too big to use with twin turbos. With a forged 402 and properly sized STS turbos you should be able to make close to 800rwhp with a cam in the low 220’s duration if everything is dialed in correctly.

If the SLP short block isn’t forged you are going to have major issues……
