If you've got a 4" downpipe, you should be able to cut up a HE351 downpipe and mend the two together. But as for making the output of a 351 match a 35, nope, they're not the same at all.

hmm yeah after further research i noticed its way different

do you figure this turbo is a good turbo for a set of twins? with a fast spooler like a k31? i wouldnt be going for any higher than 600, and the drive pressures problem of a 9cm housing worry me

I'm hoping to get a kit together like that, some budget twins for those who want fast spool up for use with k31 or s471

it would be like driving a stock truck, but with uber horsepower

is it worth it to make the wastegate hole larger, just big enough that the flapper covers it?

also, could one take the "flapper" out, and replace it with a larger disc, and make the hole even larger yet? or would the wastegate diaphragm not be able to hold it shut?

theyre everywhere. post a want ad, i bet theres tons of 3rd gen guys takin them off their trucks to replace with bigger turbos. make sure to get one from 04.5 and up i think (correct me if im wrong). those ones have a 4 inch elbow, and arent the he341

you'll want a 04.5-07 He351, one with the elbow will be a little easier to use.

the 03-04 he341 is not much better than the hy35 us 2nd gen guys try to ditch.

the he351 is better than 35/40 that many people paid near $1000 for new.

HE351 is a 60mm if i remember correctly. well worth upgrading to

00 3500 dually, 5 speed, 4 door, Gauges, with Quad Adrenaline, Raptor 150 with 1/2inc fuel lines, 4inch DP 5inch exhaust, BHAF, SBC DD clutch, good for 353.7hp and 938.2ftlbs torque. and more to come. Update:HE351cw and CCP 150hp injectors

plus a faster spooling, more efficiently designed exhaust housing.
