[streetrack 3vz ht]

Having fun at the track


this montage is not my video but a cool one
Willow Springs Int'l Raceway. Rosamond, CA on Vimeo

check 19 seconds for my mr2 and 32 seconds for the driver lol

here is my mr2 v6 in the 'smoke screen video'

Nice to see a V6 being used on a track
What else is done to the car ?

Nice vid, thanks for sharing

[1stgen]

Bah I live so relativly close to the tracks but never go....such a slacker

[streetrack 3vz ht]

nice to have some international views

this 91 hard top car has a 93 3vz with the low geared n/a open transmission
, timing bumped , and the air fuel mixture tuned, cone intake and pretty heavy and stockish duel exhaust

since ownership i have added
H R springs
rear konis(the fronts i got were blown)
front modified st sway bar

spoiler, engine heat shield, and a few other things removed
needs front shocks, brake pads, full bushing kit asap

was running front toe out with zero rear toe .. front and rear camber

im going to do a power to manual steering conversion

when i get the coin might front coil overs with stiff front springs later , camber plates, rca's , brake ppv and lighter wheels..


i have noticed hardly anyone tracking the 3vz.. one guy took some easy laps in his but not too many people.. a friend with a 1mz was there and had issues after 4 laps. might be bearings .. his issue scared me a little but my car seemed solid with the exception of the gear popping issue
peace

Ahh ok, so you got the S54, right ? I have a '92 and it'll be running within 2 months again.. 3VZ with modified heads, fidanza flywheel.. Koni's all around and racinghart lightweight wheels.. other then that pretty much stock. I use the car for trackdays too and I was wondering if I was the only one around using the V6 for the track haha... good to see some V6 action !

How does the back-end feel compared to a 5S-FE/3S-GE ? Does it feel like you can rotate the car easier with the throttle ? Or is it just planted more because of the extra weight ?

Did you had any cooling issues so far ?

[Denz]

I loved this video, inspires me even more to do my swap.
Just wondering what sorta MPG you get on the open road with this thing?
Also I was hoping to maybe track mine if/ when I do it, how does the open dif handle the power?

[streetrack 3vz ht]

s54 i think that is the stock 2.2ltr trans lol
did you drive the car with stock then modded heads? how was the difference?
how bout the flywheel which sounds fun

no cooling issues.. i should get some gauges however .. the rear felt hooked up but a little waggy with 50 series tires, zero rear toe, and old ass stock front shock. stiff front shocks will make the rear plant and me feel better - it was scary going down thru the blind s turns after the bowl. . i also dont like non linear springs which add to the bumps during full g loads when the springs are already compressed in the rear... you can see the bottoming on the fast right hander before the bowl turn

so on stock springs i dont know how different it would feel from my n/a car...probably not much...
the lsd is not a huge issue at this power level.. the key thing is to have a nice front sway or if you have coils have really heavy front springs to plant the back... and only use the stock rear bar or no rear bar .. anything other then stock rear is a bad move

that being said i would love lsd but i but for now i prefer the short gearing with the 175-180 whp im running

here is another vid of me vs a fairly sorted 3rd gen.. its my cars 1st day with stock pads and the crap front shocks plus i had a passenger . not sayin i can beat a 3rd gen but i can come close to this guy im with a few more mods

YouTube - mr2 day 5 29 09 jim k and mr3gen race...

i have one more vid of jim driving then me driving a little quicker in a few spots after learning the track a bit more

[streetrack 3vz ht]

Michel where are your vids bro??

sounds like you have a great set up .. i need light wheels
what is your alignment ?

do u ever have issues at the track?

peace
jeff

[Michel]

I'm not driving with the V6 just yet.. the heads are getting prepared as we speak, then the V6 will find its way into my mr2.. I haven't done any driving for a year lol. Will be fun on the Nordschleife haha I definately will upload some vids as soon as it runs.. I'll keep you updated.

ps. according to most V6 owners, modified heads can deliver anywhere between 10~30hp, depending on quality/craftsmanship.. I'll visit a dynojet to see what it can do but so far most other V6's are pushing like 200~215bhp.

I had to watch these again. It just looks like so much fun.

Yeah, non-linear springs are an interesting sort. I've found the stock springs much more stable and predictable. My Sportlines compress quite a bit as well under full load, and it sometimes hinders quick direction changes, but I'm not bottoming out yet. The damping rates on the Bilstein HDs might help that. I have the TRD front and rear sways, and the rear is definitely more tail happy. I kept my stock bars, thankfully, but I'm gonna try some other balance changes before I replace the rear. I'd like some wider rear wheels, but with as much money as I'm spending on my swap, I doubt that'll be a possibility until later, after body work and paint.

I have ported heads on my 1MZ too, but since I've never driven a normal 1MZ MR2, I have no basis for comparison. It pulls very strong though, and 1st gear WOT lifts the front end and squats the rear quite a bit (thanks to progressive rate springs and the super strong S51 1st gear). My injectors were cleaned and flow 10cc higher (to 255cc/min @ 43 psi, 297cc @ 50 psi) than before as well, so I can't wait to hit the dyno and see what I'm making.

[U-235]

Awesome. I can't wait to get done with mine so I can take it out.

nice vids streettrack! what series tires are you running?
i've got a 91 N/A with 1mz on the way-hopefully before the end of the summer- that i intend to track. haven't decided on wheel sizes/tires yet. 205/225, or 215/235?
the plan is s54 gear box, stock 1mz, no lsd, koni yellows- not sure which springs yet.

It'll depend on your suspension setup for tire size determination. I'm using 205/225s, and with the TRD front and rear sways, it's a little tail happy, so I could do with a larger rear tire to stabilize the rear or use the stock rear bar again.

[JimKing]

I'm using 215/45-16 front (on 16x7 rims) and 245/40-17 rear (on 17x8.5 rims), TRD springs and sways on my 91na hardtop chassis. It felt pretty good, but I didn't get to drive it much on the track yet. Jeff's car felt remarkably stable for his setup. Lot of fun.

Shifty, since you're planning on tracking your 1MZ swap, you should know mine spun a bearing just 4 laps into its first track day. Probably from oil pickup problem, though I can't be 100% certain. Look for my upcoming thread on an oil pan baffle setup in the v6 section on the other board. You might want to consider something similar, or at least put in an oil pressure gauge and keep a close eye on it.

[Jason.MZW20]

Has anyone done an analysis between the 3VZ and 1MZ pickups or oil routes? It looks like both the 3VZ and 1MZ's rear heads will pool oil, unless the 3VZ has a provision for that that the 1MZ lacks.

And I've noticed that when Toyota gives their cars to the media to be thrashed, they overfill the engine. I found that surprising even for the IS-F, with it's head scavenging pump. I can't find the video anymore, so it's likely the BBC told YouTube to remove it, but when the IS-F took off from the start of the Top Gear test track, it blew a TON of smoke out of the exhaust suggesting an overfilled crankcase.

congrats streetrack 3vz ht
you have built a nice performing and sounding exotic

[streetrack 3vz ht]

thanks ferrari.... i didnt build it though im sorting it very slowly

btw i have lots of rear camber given to me by the h&r springs and their big drop . a lil too big possibly but it works

ya i would like to know a little more about the rear bank.. im leaking a lil oil back there

get a nice front sway to plant the backand get some front camber and a good alignment to help the car turn

i dont have any experience with aftermarket rear sways but dont think they help

i have 225.45.15 f
225.50.16 rear with the s54

[ShiftyJ]

thanks for the help/advice/setups, Jason, Jim, and Jeff!

I'll check out that baffle, Jim
