after working with a honda for the last couple of years i know theres parts of one model thatll fit another(h22 into and accord engine bay and type-r bit that fit same gen lesser models)

what zed parts are interchangible and if theyrs any benifits e.g plenum..injectors...throtle bodies...pistons so on and so forth

TT injectors are a useful mod into an NA i'm told.

NA rear end onto a TT livens up acceleration with a lower final drive, reducing top speed accordingly

 

Other than that there isnt much you would swap between the two cars.

 

From the nissan range, R33 GTR front brembo calipers are a bolt on upgrade to the Z32.

Maf from a Q45 is a good upgrade as well i believe

 

Other than that there isnt much I can think of. The 300zx is up there with the top of the line nissans (especially of its era) and so most of the bits from the 300zx can be cascaded down to 200sx's etc (Maf, BMC rear brakes etc) But not much in the nissan stable to bolt onto a 300zx!

what would the tt injectors do...would you have to change to the tt fuel pump as well as

and sorry(i need to think out my q's in one part)wot difference is theyr between the tt and na rear ends

Basically the diff on an NA and a TT is different, lower ratio on an NA so rather than being geared for 186mph as a standard TT is, with an NA rear diff it works out around 165mph. Obviously a substantial drop but it effectivly shortens all the gears so the car accelerates considerably faster.

 

TT injectors on an NA without supporting mods would just make it run crap basically, but IIRC standard NA injectors are 270cc and standard TT injectors are bigger at 370cc. So if you had headers and breathing mods and an increased rev limit via a chip you MAY find that the standard NA injectors cant keep up. (Much like on a TT with bigger turbos/boost turned up high on standard turbos they can run lean without upgrading to 555cc injectors, or larger) So since TT injectors are cheap, plug in fit and readily available it offers a useful overhead in the fueling department for mapping with.

 

I dont think a TT fuel pump would be required. I think there is a difference in the control of the pumps but I think the overall flow rates are the same (Could be wrong) I think a TT fuel pump can run at slow medium and fast, where as an NA pump just has slow and fast?? I might have made that bit up though.

thank man ill look into it a bit more

the local scrapie has a write off tt in im just wondering wot parts i could take for my n/a without paying overblown prices

Tbh like the cars parts are dirt cheap and are readily available. Have a look in the for sale section lots of cars being broken. There isn't much to swap between them to be honest other than turning your na in a tt. It can and has been done but it's often not worth the cost and effort when tt's are so cheap and readily available.
