Z32 TT guru's step inside hp questions

Ok guys first off thanks for looking.


Alright Im getting anxious and need to know the estiment on how much power I'm going to have to the tires...

I've got a TT jdm motor have brand new rebuilt t25 turbos which were the stockers that I had sent off.
Z1 ecu bought from z1 for 300
550 purple top injectors,
Cold air intake k&n filter
Z1 side mount intercoolers
Z1 hard piping
Z1 boost jets for 14lbs
2.5 down pipes+ test pipes
No cats, rs type burnt tip mufflers
Stock clutch
The high dollar plugs z1 recommends for the tune.
Ecu is based on 550 injectors, 5spd, etc

I've been told anywhere from 300-400?!?!?!?
Has anyone had a similar setup?????


I am converting it from a us white z32tt auto to the jdm TT 5spd

Just got back from track and ran a 8.98 with a 2.1 60ft and 78.79 mph. This is with USA TT and a auto tranny with a cheap ecu from concept z with 14lbs injectors. 18 ich wheels and 275 street tires. My guess I'm right around 265rwhp.

Not bad for a dd car but Im hoping to get in the low 8's with the 5spd and other ecu with 550 injectors and exhaust work. Think it will happen?!?

Thanks for looking
Chris

I'm not a guru, pro or anything but I think at least 300, a friend pulled low-mid 12's with pretty much the same setup. hp ain't shit torque is. auto is boring but faster shifts than any 5 speed

2.5" exhaust and those intercoolers are going to hurt you.

I'd guess 325.

Sorry for not being clear.

Stock IC piping is very restricting as well as 2.5" exhaust (though a large improvement over stock). I'm looking to obtain 400whp on 93 octane on stock turbos because I opted for a 3" exhaust setup and 2.5" piping with Ash massives.

A dual intake setup (Selin dual MAF translator is best) would help you get more power out of this setup.

If you haven't bought anything yet, i'd say go for 3" dps/testpipes to get alot more power out of your build.

Crap, crap, crap!!! Where were you when I ordered all that??? Only thing I havent ordered yet is the z1 chip for the 550cc injectors which is only 50 bucks, and was going to order z1 intercoolers the other night until I heard you say not to... What intercoolers should I go with? I was told they were the best?!?

That's sounds mean but I don't have the money to do that right now maybe a later time... I want the most power for a bargain that's why I'm doing bolt one I stead of pistons, cams etc etc.

Why run 2.5 intercooler piping, and why 3" full exhaust???
I want to achieve around 340-360ish to the tires.... Please enlighten me on how to do this a fast cheaper way then building shortblock....

300zx and bargain usually don't mix to well LOL! Do u know what type of stock turbo you have? turbos from auto engines have more response were as turbos from manual engines have more power output potential! Do you have a true cat back exhaust or do u just have welded on mufflers? A true cat back is gonna be alot better! If you do have a cat back then just get a pulley kit, upgrade the clutch, and then get her dyno tuned since you have a chipped ecu, that should get you in your in the range of you goal! Stock Tt engines put out about 250-260whp and are rated 300 crank hp, its been advertised that with an intake filter, cat back exhaust, and ecu upgrade that you can make about 400hp! oh and also what kind of tires do you have, that can make a big difference on the strip!

As of right now I'm tight on money due to just now jumping in and buying this z! And buying all the parts for it aswell. That's the only resaon I'm on a budget now 3 months from now I could prolly afford the 3" exhaust and piping but I will be driving this z everyday! I want something powerful yea but not Racecar fast lol. Something that when some punk ass kid in his daddys vette pulls up to me and laughs that I get the last laugh ya know?!?

Porting the plenum?!? I thought about doing that at home with my dremel... What are the gains to that...

I have manual turbos which were rebuilt zero miles on them, so hopefully they put down some nice power for stock turbos.

just wait the 3 months and do the full 3" exhaust. what i meant to say about ported plenum is the Extrude Honed upper plenum from Z1 of Stillen. not something you can do with a dremel unfortunately. although if you do get the Z1 throttle bodies you can port match the plenum with your dremel. trust me the extra wait will be worth it.

it's like i tell my customers. if your going do do it, do it right the first time or don't do it at all.

I had a s14 that I put a ls2 with ls6 intake heads cam In and made 394 and loved it but, it got boring quick. I traded it for a rock crawler which I still have and felt the need for speed and built the rb25 series one with a holset hx35 top mount turbo that's my DD. Its fun for now. Lol.

Will I find the ported plenum on z1???
