sooo anyone that doesnt have a lsj put the Harrop HTV1320-LSJ Supercharger with the tvs pulley on yet if so is it worth it

 

no ones done it. most people who add a m62 find its more than enough power. Also, a TVS would require an engine build for a 2.2, and unless you run a large pulley, it will require an engine build of the 2.4 as well. Its a costly piece for us non-LSJ cars. I will one day run a TVS though

 

agreed me to ive been thinking of doing it for awhile but i want to break in my m62 for a lil bit before i start doing that stuff

 

well, i can afford it now, but if i do it, im going all out. im not just gonna buy rods n pistons and call it a day, i have $7k mapped out in performance mods, including a fully built and ported head (an aftermarket head at that). It should be fun if i ever have the cash to do it all

 

Lets see $1800 for Harrop and still have to buy all the supporting mods, or $1200-$1500 for everything from a guy that went Tubro...

 

here's my build list
BLOCK BUILD
Eagle Forged Rods $350
Weisco Forged Pistons/Rings $495
Cometic Head Gasket $95
ARP Headstuds $140
Balance Shaft Delete $225 +s/h

$1,325


HEAD BUILD
GMR Valve springs/retainers/seats $650
GMR .5mm Over Inconel Valves $395
Comp Cams Blower Camshafts $460
Ported CNC Aluminum Head $1,540 +s/h

$3,100


SUPERCHARGER PARTS
TVS 1320 Supercharger $1,750 +s/h
Dual Pass Endplate $105 +s/h

~$2,000


SUSPENSION PARTS
Eibach Front Sway Bar $180 +s/h
Steering Rack Spacers $45 +s/h

$250


EXHAUST SYSTEM
3" Catted Downpipe ~$100 +s/h
3" Catback $580 +s/h

$700

All these prices are assuming I buy new, but im sure with the 30 some TVS buys, some will change their minds or go turbo or decide its not worth it, so ill get that guy cheaper. I hope to get all of these things cheaper than i listed, but still, i listed the cheapest NEW prices

 

You're forgetting labor. And unless you have a crap load of tools and resources, you wont be able to do all of that yourself.

 

im aware theres install costs. I dont have any estimates, so i dont have an estimated price listed with the above

 

well i wonder how much power will be coming out of an 2.4 or 2.2 with that on maybe way more than a turbo???

 

im hoping for 450whp, though i'd be happy to see 400whp

 

It will be hard to say till someone does it...

With an engine build and a little extra displacement.. who knows?

 

well, m88 got 400whp with his stuff, but had a lot of knock. im going to be running a lower CR than him, a more heavily ported head, possibly raised redline, and more displacement. i should hopefully be seeing the same numbers as him without the knock, though hopefully ill see higher (im hoping the CNC head will do a lot for the TVS guys)

 

I wish i had a car garage to do all of this ****.. Id LOVE to work on cars...

m88 had a non-lsj? Damn...

 

no, he had a LSJ. Im just using him as an example ecause he currently has the highest whp numbers for a TVS cobalt

 

i think i might try it!

 

hunter your also forgeting about fuel upgrades.. ill have a fully forged/bolted 2.2 with a procharger and nitrous if it doesnt make enught power im going to purchase a Tvs

 

i already have a set of 60's. If my fueling requirements go above those (which im sure they will if i reach my goals), then ill deal with them then

 

whats the difference between neutral balance shafts and the balance shaft delete kit.?

Wouldnt you get the same results?

I just want to spin past 7k safely

 

neutral balance shafts are still balance shafts. theyre just neutrally weighted (hence the name) instead of the stock one that have a heavy side and a light side. the delete gets rid of them altogether
