You can do the following and should easily break 400rwhp:

4.0L stroker kit $3-5k
Bare short block (reuse your own)
Jun 282 cams (not sure on price $800?)
Built heads $2-3k
Custom intake manifold $2-3k
Stillen G3 intake $450
Z1headers $800
Test pipes $300
3" exhaust $1200
Lightened flywheel/clutch combo $1000
Fuel system to support the power $1000

Total cost $15k-$20k with labor

Note: you can run dry sump and gain a significant amount of HP but you will be paying north of $12k for it...

If you run a custom intake manifold, why not do twin 70mm throttle bodies of 09+ maxima and custom intakes.

I thought 1slow370z ran stock internals?

He ran forged rods and Pistons... Basically a stage 0 short block from GTM.

There was some slow secret sauce poured into the trans to help with the higher rpm shifts tho, eat that TSM lol

Per his build thread, it's stock pistons and rods. Is that not the case?

They were stock specs... I believe that is what he was trying to get across. It was only for reliability sake... He did not get any performance benefit except for reliability.

Does the 4.0 kit keep the stock cylinder bores, or does it need to be sleeved? The 4.5 needed to be sleeved, right? Isn't that where a lot of the cooling issues popped up?

Ah, that's not how I read it at all, and I must have missed the parts on the build list. I'll take your word for it since you've actually seen the car.

The Z-1 shorty's and test pipes don't make sense after spending all that money,
Full length tuned headers are the only way to go.

From what I have seen on Z1's dyno the Z1 headers make more peak power than the FI Longtube headers...

Just to weigh in on the header discussion, I'm running the F.I. LTH's and I make 345whp on a dynojet...so same or more than the z1 shorties. I also make alot more in the mid-range than friends that have dynoed on the same dyno with the Z1 shorties.

Elmo370z · 01-22-2015, 06:26 PM

But from what i read doesnt z1 dyno read 20-30% higher?

DR_ · 01-23-2015, 10:15 AM

Anyone mess with the Magic Screw?

Elmo370z · 01-28-2015, 10:15 PM
