Going forge

[neysha_eddie]

ok so i'm planning rebuilding a motor for my msp since idk how bad the previous owner beat the car so need some help in finding out everything i need not planning on doing anything big boost top 14psi... i just want build a strong motor for a daily drive so can i get some opinion on which way should i be heading?

hmm can u run 14 psi safe with just pistons and rods?

I would think you need atleast a welded LSD and stronger gears for 14psi

 

[SleepyMSP]

gears no...but LSD yes...there are a bunch of people running 14+ psi around, its when you get over 250-275whp that the tanny gives out and you need to move to par gears, or keep spare trannys around

 

[Ricktalife]

if you're running safely under that, say 200 whp, would you have any tranny problems in the long run?

 

[808MP5]

I think if your boosting 14psi you are probably in the 250-275whp range. 10psi on a stock turbo w/supporting mods and your already above 200whp

 

[Speed3.5]

tanny holds up to 300whp but you have to shift properly and not aggressively.

under 200 is no problem except lsd which could give up even at stock HP.

up to 14 psi could be achieved and have it reliable by just upgrading rods and piston, everything else will hold up unless he decides to go over 15 psi.

So when u guys talk welded LSD's are they literally welded so both the tires spin at the same rate or u mean welded just for strength?
Im used to 240's and drifting so with those cars, A welded lsd greatly improved your ability to go sideways.
But i dont get why you or how it would work to weld the LSD on a FWD car.....idk im still learning

 

[stdntDrvr]

welded for strength.

 

[shane02pro5]

Welding only reinforces the diff casing.

Also the tranny is a crap shoot. I blew 3rd twice once at around 230whp and again at around 250whp. Both times were with casual driving and clackalacka! Most issues are in the early 02 models which did not have revised shiftfork and synchro design. My second was with an 03 tranny but still let go.

 

[Caseman97]

so what kind of power can you put on just using bolt ons and not forging or getting new internals?
I want to eventually get it forged but it's gonna be the last thing im gonna do since it's expensive and what-not

 

[stdntDrvr]

200-ish whp? maybe a little more? 10psi with supporting mods (fmic, full exhaust, boost & wb gauges to monitor everything)...there's a thread stickied about this.

 

[protegerider]

depending on what tuning system you have and your combo of bolt ons you can get a sufficient amount of power, but staying under 10 psi. imo you should build your engine first, then bolt on. that is my plan, rebuild the engine strong. that way you have a good platform to work on and you dont have to have to worry about blowing your junk later down the road.
