i have a turbonetics single turbo kit, however in my pursuit of never ending power ( i shouldve just bought another tt kit, but i failed at that and got a st)

anyways, heres what im getting

wiseco pistons 8.5:1 not sure what bore yet...
eagle rods
cometic metal headgasket
rc750cc injectors
cjm fuel return setup
jwt s1cams+valvesprings/shims/retainers
utec
gt35r or hks to4z
alphawerks headers (they fit right onto the tn piping)

now while ive got the motor out, im debating if i should get all my headwork, and just do it all right the first time. however my one question im concerned with, should i sleeve my block? i know sleeving is a pain in the @ss, but as a safety precaution (the z is not my dd btw). any ideas are well appreciated. im just waiting for the "sell your st and get a tt" but thats not happening, i kinda wanna play around with the st, so any input, whether it be good or bad is appreciated

 

I wouldn't worry about sleeving

 

Do you do alot of drag or track racing? That would make the difference in weather or not I sleeved it.

 

Good luck with the build, with a single, I probably would not sleeve. I am planning a build around 550 whp, and I am not going to sleeve. The headwork, I would probably through a port and polish in there, why not.

 

Either of those turbos aren't going to do anything.... there is to much back pressure with 2.5 tn piping. You have to change all the piping out, 3in out complete from the exhaust housing, Bigger FMIC, Better WG, .... alot of work and $$$, Just ask Taurran he will tell you

 

i want about 500whp. i hear the turbo maxes out at about 450-ish?

if the piping is too small, i assume you mean all the piping from the turbo and back? i have a tial 44mm wastegate already and a new custom intercooler with custom endtanks. so goin big with a single is absoletly useless/pointless?

 

If you just want 500whp than you will hit your goal, if you use all of the same piping.. your dyno graph will look very linear all of your power will come in at once, and as your raise the boost the less gains you will see. Also the exhaust housing on your new turbo still has to be a t3/t4 flange in order to fit the piping coming out of the exhaust housing. So why even get a Hybrid gt35r turbo when it isin't going to do much... why waste money on a new turbo? Just sell your kit and but a greddy tt.

 

so in essence it will look like a honda dyno with boost instead of vtec? and the tn kit can accomplish 500whp on the 60-1 and all piping/wastegate/fmic, etc?

 

^ yea the max power I reached on a tn 60-1 turbo was 488 at 13.5 psi

 

hey d350z10 i pm'd you

 

First off, I wouldn't bother sleeving the block. You're going to be running into many other bottlenecks before you have to worry about reaching the limit of the stock sleeves.

I wouldn't personally bother with the alphawerks headers. I think they end up being more of a bottleneck with the crossover pipe but then again I have no solid proof. I DO know that they will delay spool slightly and will leave you less room for the downpipe. If you plan on doing a custom downpipe then you will most likely be restricted by doing so.

Forget the cometic HG, it's basically stock. Go with the HKS headgasket.

Go with JWT S2 or C2 cams, or go with GTM turbo cams.

If you can fit it in your budget go with some CP, Arias ED, GTM, or PF JE pistons.

 

A GT3582R would be an improvement for higher power depending on the turbine housing you went with (I'd go with the .82ar T4 housing). One of the restrictions on the 60-1 turbo that comes with the kit is the T3 turbine housing. You'd certainly be opening up some power up top if you go with a full T4 turbine housing, but you're obviously going to have to at least weld new flanges on the hot side piping to accept the turbine.

Believe it or not, 2.5" downpipe can handle a good amount of power, I just think the combination of the T3 housing and the up and down pipes contribute to the bottleneck.

 

hey drift let me know if u want me to stop by and help ya on your project since mine is ...well broken....lol

 

hey, just realized your from around here. your that silver z i always see round hwy 100? if your the guy im tinkin of, remember doin a couple runs with a yellow zo6 a while back? thatd be me lol. we should defiantely meet up sometime.

 

Looks ambitious. Personally, I wouldn't try hacking up the TN kit to make big power... I think there are too many bottle necks that will keep you from hitting your goals. For the $$$ and time invested, go custom, or go TT.

Also - sleeves are a waste for anything in the 600whp and under category IMHO. And it's already been said, but HKS head gaskets are almost mandatory at this point for anyone building. Just my

Good luck and keep us posted.

 

What about the gtk turbo's anyone trying anything?

 

Theres at least one Z with a built motor that will be running a GT-K... I'll let that person share their setup though...

 

GL with the build. Where are you getting it tuned? For your particular project, Sleeving is overkill IMHO.

 

The turbo I'm running is basically a water cooled GTK 650 with custom turbine and compressor housings. I believe my turbine housing is a bit larger AR so it should flow for more power up top. We also did a lot more than simply swap out the turbo, so it would be hard to compare the output of both setups.

 

There was also a guy in the Mid-A who did a GTK turbo "upgrade" with 3" downpipe, bigger intercooler, etc. But from what I heard there ended up being another bottle neck somewhere in the system. Don't know what came of it or if the shop that did the work wants to share, but from what I understand - simply upgrading the TN kit is a lot easier said than done.
