needs advice: SS m0 kit vs Top Swap

These posts made me laugh. You guys just made my night lol

Ok the amount of stress that whipping a M90 into full boost progressively on most setups isn't even comparable to the amount of force jumping into boost on a turbo.

You're forgetting that 10psi out of an M90 is much different then 10psi out of even a small turbo like a 61.

Turbo v. Positive displacement S/C are two totally different animals.

Yes. And what I'm saying is that 6psi with a base non-intercooled Z3 kit will not destroy your trans anymore than a topswapped setup would. You'd probably run 13.9 on a good day with your average topswapped 3.4" setup and a 13.6 with that base kit with a much easier install z3 kit. Also easily upgradeable.

I'm not disagreeing with ya bro. But he has a $2k cap and best bang for the buck in his position would a S/C setup. Granted he could grab a used turbo kit off the forums. Ive seen many go for around that price including my original lol.
 
And to everybody else thanks, this whole post was very helpful....and i wish i could find a turbo for 2 grand!
 


Topswap. I have a friend that did the SSM90, the single belt setup sucks and it ends up costing more than a topswap most of the time unless you overpay. Average price is around 300 for the hard parts, then around 150 for gaskets and small parts like coolant elbows. Good luck with the swap man.
 
alright so i've decided to do the regular top swap, i got a guy selling me most of the hard parts for$350-450. Im gonna look into supporting mods as i go along,tryna get around the low 14's high 13's!

Nice man, if you pay over $350 you're paying too much though (unless the blower's ported). Make sure you check the heads too to make sure they're not cracked. If I had the cash at the time I would've gotten mine dipped & magnafluxed, but I didn't so I just took the chance. With a good tune you should be able to hit high 13s easy.

Im gonna tell you right now you want headers immediately or you will burn pistons on the top swap.

Not true, headers are a good idea, but after my swap I didn't even have so much as a downpipe yet and I was MAXING a 3 or 4* KR in like 1 or 2 areas, most were around .5-1.5 or 0, which we were able to tune out for the most part. I think there's like 1 area at the top of second or 3rd that hit .5* post-tuning and that was before the dp. But that's with a stock 3.8, if you wanna go smaller you need headers.
 
well im definitely gonna get headers and 1.9 rocker arms,what pulkey should i be able to run?....also whats the average price for dipped and magnafluxed heads?

Headers are a must, you should be fine on a stock pulley and mediocre tune.

I paid $190 for a race shop to rebuild my heads.

cool,so with headers,rockers,and a tune you still dont think i can a lower pulley size tho?
Click to expand...

With a GOOD tune you should be able to run a 3.5, but if mini is running a 3.4 I don't see why you wouldn't be able too, but you just have to get a good tune. If you're getting a canned tune...I wouldn't drop lower than a 3.6.
 
Im plannin on going the same route as u man but im wanting at least mid to low 13's in the 1/4. From what i know i would say u still need the small things for the 3.4 pulley too. 180 t-stat, colder plugs, an such should hlp out too. Headers an a fenderwell intake grants even less chance of having kr on your car if u drop smaller pulley sizes
 
You can't run a 3.4" on a top swap or SSM90 kit without an IC, or a cam or headwork...its not happening.
