how to beef up the z33 engine
hey guys,
kinda new to the hook up scene so I needed to ask a few questions. My car is about 3 months old so in about a year or so im planning on puttin on a twin turbo on my car. I want to make my car rock solid so that at normal boosts where i wish to be putting down around 400 rwhp my car will have no worries of anything breaking, and if I wanted to boost it more and get 100 or 200 or what not, I wont break the engine. I need to do my research but I was wondering what you guys could tell me about what I need to do to my engine, what parts need to be replaced, and how much im lookin at thx

Ask again in about 9-18 months. Right now if anyone gives you an answer it would be speculation. At this moment, noone has gotten really big power out of the car. Actually, a realistic answer would be you'd have to swap the engine out for something else, RB26DETT, something along those lines, and that could run $12k and up.

I hear and read sleeving alot as one of the ways to strengthen. For those unfamiliar with the term, what is it exactly do to the engine? Pardon the newbie question.

Sleeves are the actual cylinders the piston moves inside of. In an open deck block you have sleeves which means there is space for coolant to flow around the cylinder sleeve for cooling. Turbo motors usually have closed deck blocks and there are coolant ports for cooling. Good motors like the 2JZ, RB26, and 4G63 use a closed deck. So to build this motor for turbo you should at least re-sleeve the block with stronger sleeves and get something like a block guard or girdle.
these parts are for honda's but you get the point. Honda B-series motors are open deck btw.
Block Guard. (goes inbetween the sleeves and the block)
Block Girdle (goes on the bottom of the block)
edit: btw does anyone know if there is a manufacturer for these parts for our VQ35DE?

prolly not yet; not that Ive seen.
I beleive the market for this stuff has to develop; before they will make parts to beef up an engine for FI there needs to be a kit on the market thats capable of producing more than 9psi. I beleive greddy will be the first to have that; and power enterprise; but both are just now coming out. I think now the fun begins.

We have a 4 bolt main so the crankshaft, crank bearings, and the bottom part of the bottom end should have no problem with high HP. The weak areas are 1st - the pistons meliting, 2nd - the rods breaking, 3rd - having an open deck. Solving these 3 problems should make the motor strong enough to handle some superpower. My plans:
Forged rods and pistons (8.5:1)
Something to reinforce the cylinders
Higher capacity oil pan
Lightly ported heads
Tomei 268 cams w/Ti retainers, stronger springs, heavy duty lifters
Some sort of plenum (LSDUnique or Crawford)
ATI Procharger with smaller pulley
TS ECU Flash w/(probably)XEDE Programmer (to monitor/fine tune)
XERD Headers
Already have the exhaust, clutch, flywheel, etc.
THE END.
Sidenote: I may sub the ATI and plenum for the Stillen. Depends on HP/dollar.

Usually when you get sleeves, they do a closed/solid deck, whatever you want to call it. My block is being sleeved at AEBS, I don't even know the status of it, I need to check. Honestly, it's not cheap, not at all, and takes a while, mines been there close to 8 weeks now I think. It's going to be expensive to beef up this engine. Building your bottom end is going to cost you close to ~$4500.00, that's for pistons, rods, sleeves and decked. That's without labor, but labor shouldn't be more then $500.00 to build the bottom. Do you even want to know what the heads are going to cost?
Edit: Checked my book when I got home, was a little off on the price.

Plus 500 for labor will be the whole motor and I suspect about 200 for supercharger labor. Maybe 4G's for a Procharger and you say 4500 for the motor. Not bad for 700 HP. Less than 10K. Can you say, "Bonus!" Yay end of year. Too bad our year ends in July.
