Z32 300Zx With Vq30 Twin Turbo Conversion


Boosted Zed
 Share

Recommended Posts

This engine is 105kgs lighter than the VG30DETT, much lighter rotating mass too. For example the cams are about .5kg lighter each.

Valves are around 2mm bigger reach and has four bolt mains. 93mm bore instead of 86mm

We decided to do this conversion as the VQ is a much more advanced and lighter motor

Yes I have done a lot of sailing to, doesn't qualify you though Rich. She will be a fast boat now. You will have to get in line, after me is John Boston then John Webb and John Bowe, who was here today for a good hour checking the car out. He was very impressed and wants a drive. THe John driven car!!!!!!!!!!Then there is Dave, a mechanic here who has done most of the work, although I think he drives about as good as you, Beer Bitch. Hopefully you won't fit in it either, which is my excuse for fats not to drive it, he he.

I Still dont see any teeth

Looking good John

A bit of bling for you, gold heat shield by DEI, it is supposed to reflect 90% of heat. With the turbo's right back and close to the firewall this should help a lot.

Motor going back in today, ye ha.

Like a rat with a gold tooth. Beat you to it Beer Baron.

so john, tell us more about the engine.

How much have you needed to do to turn it into a viable track engine, just forged internals and a few odds and ends or does the factory vq30 scrub up ok block wise and just needs much the same love as say an rb26 or similiar.

To put it shortly, do you have to spend a mint to make this engine really go?

i already gather that ini your instance your going whole hog.

Yes Neil it should give you a run next time we meet. No more power, about the same we suspect, just much lighter, by 105kg. Not big money at all using a stock VQ30DET $1500, then added strong valve springs, dry sump, custom plenum, top feed fuel rail and exhaust manifolds, so it should be efficient. Motor only cost $2000 and has four bolt main, hard annodised pistons, Molly coated skirts, 93mm bore compared to VG30DETT so shorter rods and 9 to 1 comp so should rev. On E85 and 20psi it should easily make an easy 400rwkw with the boost button on the straights. Compared to the VG the VQ has a much lighter rotating mass, the cams are all hollow with narrower lobes and wasted down and all four are about 2kg lighter, a fair bit, alloy buckets with metal shim 39 grams each compared to VG hydraulic 63 grams each, multiplied by 24 adds up to, the cam gears are about half the weight, crank pulley is much lighter although now has a Ross Racing custom balancer. Even the ignition coils are by about 35%. The block being alloy is the biggest weight saving.

The VQ has better port design and stock valves are around 2mm larger.

We do have a spare block with Darton Sleeve kit so can go up to 100mm bore and with VQ35DE crank we have can go 3.8 litre and will use forgies then and bigger turbo;s and make easy 500rwkw.

In addition the VQ30 has another improvement being crank and cam trigger rather than crank angle sensor. More pictures to come, engine and gearbox have just been put in

New dry carbon targa roofs ( no gelcoat, all carbon fibre, Kevlar, Polly core and epoxy resign), now 980 grams each compared to wet carbon 1.55kg previously, so over 1 kg saving off the roof.

    • Go to SP mufflers and get the muffler of size you want and make a nice mid muffler. It's about that simple! I have 2x 3.5 Magnaflow straight through Mufflers and while it's pretty loud with the Varex open, it's quiet enough with the Varex closed. You can also buy off the shelf Magnaflow straight through mufflers as well. You also have a turbo to quiet the car down too. Don't overthink it. Buy my extra Magnaflow muffler sitting on a shelf doing nothing (buy it new, ignore this part)
    • Centre-offset muffler under the floor, same as stock. Just....3.5". The change from straight pipe there to centre-offset will mean that you need to remake some of the pipe (add a bend or two).
    • Hey guys. So my R34 GTT has a custom 3.5” exhaust (done by previous owner) with a high flowing cat, and then just a Varex cannon muffler on the back. The car does drone alot and is really loud even on highway driving just cruising, as you can imagine due to the Varex muffler basically being a straight through with the valve open. As much as i love a loud RB, it can be a bit much with no other muffling in line and just driving casually. I wanted to lower the volume output on the exhaust a bit, as well as remove the drone (probably a way to do both at once), and was going to do it all myself as I am a fabricator and have done exhaust work in the past, so the fab work isnt my issue, im just not sure on the right product or type of product to use to get the job done, and i doubt an exhaust shop would be wanting to help me as they wont be making any money from helping me, unless they supplied the product? Anyway any help or guidance in best way to approach this would be awesome   Thanks in advance
    • Meh, whilst the Honda is a "really" good car and has potential if you want to drop coin on, it was uninspiring for me to look at, but, it did serve its purpose and is now in the boys hands, his happy, his girl is happy, as she wasn't to keen on the noisy old Patrol, and most importantly, the Minister for War and Finances is extremely happy that her "little baby boy" (6'2 nugget who is currently training to be a copper, which will make 3 coppers in the immediate "circle of trust") has a well sorted reliable car that doesn't guzzle diesel Me, I'm more than happy with the NC MX5 that I replaced it with, it's a fun little car that I like looking at, like driving, and yes..... I do like the fact that the maintenance and modifications that I have done/will do are plentiful and relatively cheap, well........ while staying naturally aspirated slow that is, and that's all I really need for a fun little daily, I can rev the 5hit out of it rowing through the gears and never really break the speed limit  In saying that wicked word, "modifications", I've already ordered something for some noise and an additional "3 ish" horse powers, or whatever it gives, in the form of a header, and, a new set of "cheapo" BC coilovers that are already sitting in the shed waiting to get put in, I had the same BC's in my old NB and found they were fine for the street, hwy, and the occasional track days I did in it, they have 6kg front and 4kg rear springs which is about 10% stiffer than the stock springs which I found worked well for their price  I've also already been in touch with MX5 Mania in Dural, so once the header is on it will get a ECUTek RaceROM tune there (I cannot rev match for 5hit, and I loved the RaceROM rev match and FFS in my old 86 "RIP") In other, maintenance news, I put some new sparkler plugs in it, and have a new set of DBA Street series pads to put in over the next day or so, I'm running the DBA street series in the SS and Honda and really like them, they work great and are not dusty at all I've also booked in a few days leave over this weekend to give me 4 days weekend do some paint correction and give the leather seats some conditioning and interior some Bissell and steam cleaning OCD lovin', the carpet and interior looks clean, but from my experience with the Bissell IRT carpet, and the steam cleaner IRT trim, looks can be deceiving I've also found that finding a detachable hard top is proving problematic, the main reason why I didn't like the NC initially was the power retractable hard top that I seen them with gave the roof line a weird look, the detachable roof though looks good, and is a same shape as a NA/NB hard top, similar, but unfortunately not the same as it has different fixture point on the front, so fitting a easy to get NA/NB detachable hard top is no bueno New Old cars are fun, cleaning, hunting and playing around brings much joy How are your beasties going? Do you still have the Skyline with the LS???, or Barra??? that you were playing with
