let me list my mods first:

a race ported motor (not bridge but the largest ports you can get)

PFC with 850s and 1300s

greddy smic

lighter flywheel

MSD 6A

3.75in mp and 3.75 in Ex



what turbo would be good for my setup if i wanted some low end power and crazy top end? (start spooling a 3500- full boost by4500-5000 rpm)

i want to hit close to 500whp maybe more. and i want to run 10s.



i know that i don't have enough fuel for 500whp so will 1600 secondarys be enough?

one more thing, i want a custom kit ( read less than $3200 )

t78

To4R

Neither of those turbo's are going to make any "real" power. Get the HKS T51R. I know you don't have the money, but save up, cause this is just the beginning. Plan on throwing the POS Power FC out the window and getting a real stand alone like the Haltech, Tec3 or Motec.

Yeah go with a better stand alone like ErnieT suggested. T51r is pricey, you could go with something like a t-66 through t-76 and maybe change to a Q trim for more exhaust flow, might help match your large exhaust pipes.

Oh yeah, and 850 by 1300cc injectors is good for about 550rwhp at 100% duty cycle and around 475rwhp at 85% duty cycle. So you really need to upgrade to 1600cc secondaries to keep the duty cycle in a safer zone. And not to mention you're going to need a huge fuel pump to keep up with that much flow.

POS PFC?! https://www.nopistons.com/forums/pub...1047683561.gif ****.. and I just bought one.. https://www.nopistons.com/forums/pub...1047683664.gif https://www.nopistons.com/forums/pub...#>/biggrin.png

Its not a POS, but if you are going after "big" power, then you really need something a notch up.

The t78 will make that power. You'd be pushing a t04r pretty hard to make that kind of power though. T70-T72 are closer to the size of a T51R but way cheaper.

The only single I'd even consider buying. https://www.nopistons.com/forums/pub...IR#>/bigok.gif https://www.nopistons.com/forums/pub...1047683894.gif https://www.nopistons.com/forums/pub...IR#>/boink.gif

thanks for all the replys

how much lag does a T66 have? and will it fit on the HKS (XS) cast manifold?

is the tubular manifold worth the money?

How much worse would the turbo lag be on the same motor with the t51r compared to say a t78?

I have a list of turbo setups on an excel sheet I got from Gordon Monsen back in the day. Steve Kan's car is litsted as having the t-66 and made 550rwhp. The turbo should work with the hks manifold, at least from what i've always heard. Its very close to size to the t-78, both can make 500+ horsepower, but you will be going custum with the t-66 and maybe save some money.



A t51r is going to be pretty laggy, its a huge turbo. The t66 or t78 are both still good for the street, a tad lagggy yes, but the power potential is very high while they still make good power on a street car down low, depending on porting of course.



I had all the reciepts for my custum t-62 kit around here somewhere and I believe the total bill was around $2500 for all the parts to make it work. The hks manifold is sweet, very nice manifold with good ports.

will a 62-1 be good enough to hit 550whp? i can get a DBB for about $1100.

I highly doubt my t-62 is good for 550rwhp, more like an easy 450rwhp with proper tuning and boost. You'd need to call up turbonetics or majestic turbo's and ask them for a quote on dual ball bearings on something like a t-66 or whatever you decide to go with.

T78 is a greddy turbo and is pretty expensive to have rebuilt, but T66 can do almost the same power and its a little cheaper to boot. I wouldn't do a ball bearing turbo due to the fact that it will be expensive as hell to rebuild should a seal go through it.

Well if I was you I will get the t70 . For the price of the turbo and the power it makes its well worth the money . I personally have a t70 and I'm very happy with it and the lag on it its not that bad . So happy hunting .

So its up and running? How do you like it? When does boost come on?

It runs very good , I hit 15psi about 4k rpm . The only problem I have at high rpm I get some break up . Dragon was nice to hook me up with his map but for some reason it still does the break up . So soon as I get some more money dyno day will come .

Thanks

What ignition setup are you running?



BTW car looks awesome

what A/R are you running on that T70 ?

and do you get full boost by 4k or does it start to spool by that rpm?

He said 15psi @4k rpm

T72 turbo with a .96, q trim, dual bb!

full boost by 3k ant tons of top end!

the T70is good too!!!



p.s at 24 psi your injectors will run out, gey 1,600 for the secondaries! https://www.nopistons.com/forums/pub...1047683329.gif
