[Lifted79CJ7]

That is one sweet ride mate! So I just google mapped Perth - is Belmont Park a dirt track?Jack

[sidewayz alwayz]

[Florida240sx]

[Robstar]

Good to see some other Perfy's in the area with a VH conversion, thumbs up mate!

[DeXteR]

a s13 with a vh45de +tt

The more I see, the more I want. Looks great.

[DJButton]

I need a VH, screw my RB... end of story.

[anyotherone]

Dude... you will be my hero if you can snap more pics, primarily of the motor with that center heatsheild off, and of the turbos, manifolds, and the clearance for the downpipes! That is exactly how I am attempting to build my setup!

[sidewayz alwayz]

bad news my camera phone peice of **** nokia n95 (au$1300) died today so there will be no photos for a few days at least. my dog just had surgury (au$1800) swollower a corona lid 3 weeks agomore bad news got the car dynoed (au$300) by a good tuner (proven) and made liitle power due to the size of the turbos (stock rb20 ceramics)only made 292bhp (yes the guy that tuned the car does know wtf he was doing as well)

the guy i brought the car off claimed 480 which would seem closer to the money.

the car made this power at 5500rpm though on 7psi and them just fell in a hole just like an rb20 would . made awsome torque though so as you can imagine ive had a couple of **** daysand still ave no info on a manual conversion ( the tune would be usable if it was manual. the auto dont change gears until you back off the throttle ba baaa ababa abaa baaa baa bababa) also have spoken to another fellow vh45 onwer (local) who has made 440bhpon a single turbo set up on 7 psi easily unopened engine.so if there is anyone that has specific info on what size turbos or turbo i should put on this thing to make 450 plus and whats the go with the manual conversion dont hessitate to let me know. but if youre just some kid with a hard on tring to make suggestions with no proven specifics dont bother. oh yes did i mention that id had a bad day

[anyotherone]

Sorry to hear that, I hope things start looking up for you soon!

I wondered if those turbos were a little small... I've been considering either two GT2871r or gt3071r turbos, you might look into bost of those. If your on a stock block and only wanting 500 or so you could probably go with something a little smaller. I'm not familiar with the RB20 turbo but I got 300whp out of my RB25det on a stock turbo.

Have you done a compression test to make sure there's nothing wrong with the motor?

[craigztoyz]

That is what I was wondering. Compression test are you getting blowby from the rings?

is there a lot of turbo lag, taking too long to spool, or are they spooling quick and the bov is open a lot of the rpm range?

with the plumbing of intake, the first would be my guess, and checking the engine. WHAT WAS THE TORQUE?? CAN YOU POST THE DYNO SHEET PLEASE thanx

[DeXteR]

. . . so if there is anyone that has specific info on . . . whats the go with the manual conversion dont hessitate to let me know.

Seems that the most popular option for going with a manual gearbox is to use the z32 6-speed with an adapter plate. There is a lot of information in this forum about this setup. There are three posts in the top of the first page alone regarding adapter plates. Just browse through the first few pages of this forum and you should find a lot of the information you're going to need.

5 speed is bettter, less shifting. Both only have one overdrive gear, so 6 speeds, means 5 up to 1.1, and a 5 speed has 4 up to 1.1, so unless you are running 4.10s in the rear, you won't want it. I almost went with a 6spd from a new 350Z, till i researched the gearing.good post above mine.

Sounds like something is wrong to me. You should at least be able to get over 400HP even on ****house RB20 turbos.

Since it's set up for T3 flange turbos now however, you have a huge range of options.

If you're working with a limited budget, slap on a couple of used RB25DET factory turbos and tune for those. You should be able to get 500rwhp out of them at least, they're a decent sized turbs.

But if you have a little more cash to play with, I personally would be inclined to find a couple of nice aftermarket T3 flange turbos... i.e. 2x Garrett GT3076R turbos + 2x external wastegates. Just make sure your oil cooling system is adequate, as well as intercoolers.

[DJButton]

Twin GT3076R's would be fantastic even with 1bar you could probably put down 500whp... I plan on a single Gt3076 to get my RB20 to 400whp, as a reference point.

the SEARCH button works great,

I have experience with both the VQ 6spd and the VG 5spd manual transmissions. I'm using the 5spd on my VH project because they regularly hold up to 500whp+ and the VQ 6spds have a lot of grinding issues simply pushing stock engines around as daily drivers.

As mentioned above, the gearing will be just fine with the 5spd too, I would reccomend getting your hands on a q45 VLSD if possible though, its a heavier more reinforced R200 variant and will bolt right into the S-chassis, I have an S14 here in my shop with one in it now. If you search around the forums there is a writeup on what axles to use, its a combination of Z32 and Q45. The final drive is 3.46 I believe? and will give you a better chance at traction.

[Mettler]

It's not heavier and more reinforced, it's just an R200 VLSD with larger diameter Z32TT style stub axles & 6 bolt flange.

[anyotherone]

Sorry, but I'm sitting here next to my Q45 R200 and my stock US 240sx S13 open diff... the Q45 case is beefier.

You are correct about the axles and flange however.

[Mettler]

Well that's strange as we have a Q45 R200 lsd and an R32 R200 open diff at home at the workshop, and have them sitting next to each other & the casing looks the same. Because the diff itself is not rigidly mounted to the body, there's no need for it to be beefier.

This requires further investigation! I'll take pics this weekend to confirm, if you're right then I'm happy to concede so long as it's proven

[anyotherone]

I see you are in the land down under, could the diff just be different from your 200sx as opposed to the US spec 240sx? They gipped us on everything else, I can imagine that would be the same as well.

No biggie, the biggest difference in the diff is what you said, pertaining to the half-shafts and axles, that's usually the part I break anyways.

I'm not sure that I follow what exactly the discrepancy is but there are actually even two types of Silvia flanges on the R200. My 91 2400SX had the 6 bolt type ourput flanges (3 tabs with 2 bolts each). There is also the 5 bolt with 5 tabs outputs (1 bolt per tab). I think the 5 bolt one is stronger because the bolts can be bigger and there are more tabs (some people call them ears, whatever).

basically one is like<pre> ||// \\</pre>and the other is like<pre>\|// \</pre>Sorry for the ASCII art

The R200 was such a common rear and there are so many combinations of outputs and ratios. (VLSD/Open, 5-bolt/6-blot, 4.089...~3.49). They came in (at least) Z32 N/A (technically TT was R230V), RPS13, S13, S14, J30, Q45 ...

[sidewayz alwayz]

will the gt2871r or gt3071r bolt on to those flanges? also im lead to believe that the car has an r32 diff but the lsd lis very loose what is the easiest way to make it locked

[T45]

what is the easiest way to make it locked

Weld it!
