ok i was just sitting here thinking and figured id ask what are ALL the mods that someone would need to build a 400HP SS/SC? without going turbo or to a diffrent supercharger that is. when i warranty is up (not for a long time) i fully intend on achieving 400 or more HP and dont know what all mods/supporting mods i would need...
can anyone help me?

 

not possible

or realistic unless ur gonna build a brand new motor but then why not fork out for a new s/c or turbo? ur not getting 400 with stock internals period

 

yes you need to get rid of the supercharger and buy a turbo.. then get into some internal mods going.. lol.. sorry man i dont think that will happen on the stock s.c

 

should have posted that but trust me i know stock internals wouldnt cut it thats why i said ALL mods/supporting mods i would need

 

you would proably need every thing in the motor rebuilt and ported and all that jazz... then you would either need n2o or like a 2.3 inch pulley and over spin the crap outta the s.c... and you are gonna need some serious cooling mods... but i could be worng.. i think its easier to just go turbo or change the supercharger

 

Take a look at Blown 4-banger's build thread. That might give you some ideas. I still don't think that it is possible with the M62 though.

 

well if ur gonna build an engine ur best bet is to go 8.8 to 1 compression and port and polish ur supercharger/head and then get a ZEX™ EFI Perimeter Plate Nitrous System and squeeze every drip outta ur car and hope u dont blow nothing up paul walker lol...just not worth it to find any other route then the right one bro but just my 2 cents

 

well I don't know the cost but u'd want a sleeved block bc our motors use 10:1 compression pistons which have almost no skirting and will scar a cylinder walls.....so forged pistons, sleeved block, arp studs, steel head gasket, built head, exhaust components, and a s/c swap; turbo; or ported and polished with meth. injection...that would be a good start IMO......and if you fall short traction mods to put the power to the pavement.....and with 400hp..u'd need new axles and of course a clutch.....you could always use nitrous...if your bottom end and head is built and spray like a mother f**ker

 

A fully and correctly built LSJ should net you well over 300. We are talking about balancing and blue printing the motor, and completely re-doing the internals, maybe even boring it out a bit as well.

Nitrous will get you there faster with a little less work, but as you can see in my sig...Me no big fan o nitrous.

 

I'd love to see one when its finished...lots of members have great builds on here, and I'd love to see some video clips/ pics when done......JBP started a build on a "750 hp" but I haven't seen or heard of any progress on that in months.....

 

thats for the most part true. The crank is the only stock internal that will handle that kind of power. its rated to 500 hp but its max rpm before it disinagrates is 8000 rpms. somone on here went to 8100 rpms and it disinagrated

 

Buy a GTO

 

ok so im taking it that its prob not possable to get to 400 HP with the stock SC so ok lets say i go to a twinscrew what internals and mods/cooling mods you guys think?

 

GTO has to come up in every thread some how some way

 

yea im not going to buy a GTO... haha although that would be 100 times easier

 

My crank is still holding and I went to 8300 rpm lots. 400hp on pump gas isn't possible in my opinion.

 

400 not feasible even with a twin screw mods/cooling mods and new internals on pump gas?

 

I'm doing it with the stock blower. Fully built internals, max head work, and retarded cams. Gas milage will be ****, but it will have well over 400 hp.

 

2.8
60's
tune
full exhaust
10.1 pistons
100 shot.

 

in the GM ecotec build guide 500hp is obtainable on 92 pump gas. It just takes bigger injectors a turbo and nitrous to get there.

 

Good luck with that I can't wait to see the results. Still don't think it can be done on pump gas.

 

GM ecotec build guide doesnt mention anything about head work till you get over the 500hp mark.

currently i have ferrera valves and springs w/ titanium retainers, comp cams stage 1 cams, wiesco forged 8.9:1 pistons, egale forged rods, ARP head studs, ACL rod bearings, Honed cylinders, 3 angle valve job on the head, and a GM ecotec build guide engine rated to handle 500hp. (need to change out the crank if i want to go over that)

 

You can only do so much with our heads, I don't care how much you say you had it ported out.

Besides, didn't you say you were going with Lower Compression pistons for your twinscrew?

Without Nitrous or Turbo, you are not going to do it with the stock M62.

 

agreed +1

 

I think thats a challenge! Not for me though, for someone with money
