have you read up on this on the forum? Plenty of threads on this

Chris06CobaltSS

I've done some research, all the responses I've seen are people saying it's not worth it. But I already have most of the stuff.

Why dont you just post your questions here

Chris06CobaltSS

Okay, so this is what I have, and I need to know what else I need to do the swap:

Ko4
Lnf intercooler
Injen upper and lower charge pipes
Injen intake
Lnf intake manifold
Lnf turbo manifold
Lnf o2 housing
Lnf coolant crossover pipe
Lnf oil and coolant lines

going to need to swap the alternator and belt tensioner. lnf le5 or l61 should all work

you dont haveeee to use a different alternator

need to swap out the one way clutch on it for a regular pulley if you dont swap the alternator. come to think of it someone had a pulley for that, ottp maybe?

Are you sure? I know tons of people who spin the 2.2 alternators backwards when they supercharge their car and it still makes power. Is the lsj one different somehow?

Chris06CobaltSS

So the lnf alternator WILL work? I didn't think it would

Slowbalt2000

iTrader: (1)

Yeah the lnf alternator would work.

Chris06CobaltSS

So I can use the lnf belt too?

Sharkey

iTrader: (1)

yes.

the lsj alternator has a one way clutch in the pulley, and its designed to spin backwards. if you switch it to run forwards the one way clutch will just freewheel and the rotor in the alternator wont turn.

ottp does have a solid alternator pulley for the lsj alternator just for when you turbo swap.

i find it odd that the other ones dont work that way, but nonetheless, good info

Chris06CobaltSS

Wow I did not know that. So I'll just save some money and buy that from ottp and not even mess with a new alternator

your going to need a saab 9-3 intake manifold, the LNF intake manifold is not going to work, trust me get some piping and fab your own cold side charge pipe also

jcobaltss

You did the lnf swap, so do you think just doing the saab 93 turbo setup be easier? Obviously the 20g instead of the stock saab turbo

Axelthered05

iTrader: (9)

no i would stay with the lnf setup

Chris06CobaltSS

So I was told I can't use my injen charge pipes with a Saab intake mani. Should I get the ottp intake mani with ottp charge pipes and tial bov?

jcobaltss

Zzp uses the saab intake mini in their turbo kit so use what ever charge pipe they use.

Chris06CobaltSS

I wouldn't be getting their intake mani. I'd be getting ottp' intake mani and their charge piping kit to go with it

Slowbalt2000

iTrader: (1)

but hes saying if you already have a saab mani then you can just use the lsj turbo lower charge pipe from zzp

Chris06CobaltSS

I don't have the saab mani, I have a stock lnf mani

the lnf manifold doesnt bolt up to the lsj/l61/le5 cylinder heads. it can be made to work (im running one on my porsche swap) however it takes some machining, and you lose the pcv valve. honestly your better off to get the saab manifold, or one of the aftermarket options. the only reason im using the lnf manifold is i have very little room, the saab manifold wouldnt fit and i want to get the car running before i spend the money and time building my own intake manifold.
