don't you ever get onto TT.net? it is much cheaper and easier to just buy a twinturbo than tring to convert one. and what makes you think a 2+2 will handle better than a smaller twinturbo with hicas?
All the smart drivers have their hicass disconnected... and also Steve Millen the most succesfull Nissan 300zx driver used a 2+2 that was converted to TT ... reason the car has a longer wheelbase... Thus it handles better It was lighter than the TT also... Its not as expensive as it sounds(well on TT.net it is) but I can buy a JSPEC TT for around 1500.00 with turbos slap the baby in and there ya have it.... and besides that I have a sweeet looking car that has been fun to work on... I've learned alot about the car along the way... I wouldnt get rid of her for less than $20,000, with the suspension, bodykit, brakes, disks, wheels, interior job, & sound system I have.

i really like the hicas, and i know plenty of people who feel the same way. the only people who buy the hicas kit are people who have problems with it and don't want to pay out the nose to get it fixed. and the 2+2 is a little heavier than the 2 seater twinturbo. a longer wheelbase only means more stability at high speeds, not through tight turns. doing a TT conversion is a lot more involved than just dropping an engine in, in addition to the engine you will also need the tranny,EGI harness,intercoolers and all the piping, fuel pump, oil cooler,radiator, ECU, front bumper,clutch, vac. assist stuff for the clutch,exhaust system, clutch pedal,variety of sensors and actuators and the main engine room harness. along with a lot of gringing and frame work to get everything to fit. so if that sounds simple and cheap, i want what you're smoking please. so good luck!

SO theres your info on wieght and other stuff.... even though it was a longer car it was lighter.... It would behoove you if you disconnected your hicass system as it inhibits performance.... ask Stillen down in Costa Mesa
like i said the TT is a LITTLE heavier than the NA, not very much. and if you were to swap the NA engine for a TT they would be really close, but i have a feeling that would be relitively impossible unless you got tons of cash and time. and judging from the lack of comment my guess is is will never happen, $1500 is just a starting off point for that conversion. and i have driven a car without the hicas and there were no gains what-so-ever. the rear end did not inspire as much confidence while hard cornering. he only got the kit because repairs exceeded the cost of the eliminator.

A 2+2 is not lighter than a regular Z. You can't buy and import a JDM Z here for $1500, they go for way more than that in the junkyards. Plus you have to make or get made a lot of other parts. Its cheaper to sell the NA and get a TT. Since you NA is so nice and you already have a bunch of work done to it, it might just be worth it to consider the swap but it will be difficult and expensive to do.

I hated HICAS, it made the car feel like it wass about to spin out, then it made the car understeer like mad.
I disconnected it and strangly the car turned in better w/o the HICAS and felt much more balanced.
Originally posted by ShaksShaun i go strictly for power and performance mods. shiney shit does not make you go fast so i do not even bother. i got a set of sheep dog BOV's recently, sweet sound, good spool up time. gotta love turbos. but i had an NA at one time too, nice car for crusing but it does not have that throw you back in your seat power that a TT does.
Well atmo vented BOV's are a performance decreasing mod! They cause over rich running on overun and can cause problems with venting metered air at high boost levels.
The factory bypsss valves are huge and aftermarket ones are a gimmick noisemaker that can cause performance issues.

you only rin rich for a split second at a time while shifting. and i would consider faster spool an upgrade.

BOV's have no affect on spool. The valve size on aftermarket valves is either the same or smaller than the stock bypass valves.
Many times I have seen them as the sourse of slow spooling because they leak boost. Since the have to have a stiff spring to stay closed at idle they are also less responsive and cause more lag than the stock bypass valves.
They are a total rice mod on a twin turbo.
BOV's are ment for cars with a Speed Density air metering system. They work best on cars hat either had no bypass valve or the stock valve is really small. They work poorly for MAF Equipped cars unless they are recirculated and the springs are calbrated correcly. The Z has Bypass valves with huge control valves so aftermarket BOV's only hurt performance.
Its not as expensive as it sounds(well on TT.net it is) but I can buy a JSPEC TT for around 1500.00 with turbos slap the baby in and there ya have it.... and besides that I have a sweeet looking car that has been fun to work on...
