Have you guys seen this twin turboed VQ? (Too bad its in a dune buggy)

http://vbxmaxima.8m.com/500HPVQ.html

BTW, where could you get a custom tranny like that built?

 

Yeah, we have known about this for a WHILE now. But, everytime I see it, I am still amazed by it. Money, I mean MONEY, went into that.

 

ewwww its a dune buggie! but woot for the VQ

 

It's a great engine choice. We have people cranking out close to 500 on a single turbo.

Where would one estimate the actual block tolerances are as far as HP/cyl? 600? 700? I wouldn't imagine a huge amount more than that. There has to be someone planning a full build that has this sort of info...

You can get a VQ30 for cheap. The forgies aren't so cheap...

 

How did they make it RWD?

 

7000$ custom trany

 

Haha, I got that...

 

It's a Porsche transmission. Very common in Mid Engine kit or Boutique car manufacturers (ie Ultima, Mosler...). Seems it is very adaptable w/ a custom made mating plate. The Ultima combines it w/a big block Chevy so it's not a stretch to mod it to fit a VQ.

Sorry to go off on a tangent but if you guys are interested in the ultimate car nut experience: Build diary of an Ultima GT-R If you look at the tranny pictures, it's the same basic tranny used in that dune buggy.

 

i was always thinking can a VQ fit into US 240sx with not a lot of money. Can u imagine RWD VQ??

 

You mean turning it sideways? A VQ30DET would be cheaper.

 

Yeah, VQ30DETs are rwd, that would be a lot of fun in a 240sx.

 

I think rb26det is a better choice

 

I think the VH45DE is a better choice than the RB26. Maybe it's cause one's sitting in one of my 240sx's....

 

I wouldn't do a VH45 or a RB26 in a 240, I'd probably go with a RB20 instead, but even that is going to hurt the weight distribution of the 240. But then again, going with those motors might make the car a kick *** drift car. A VQ might be a way, but I think you may have some issues fitting it between the strut towers as it's probably gonna be pretty close. As for the dune buggy's, I know that the porsche tranny's seem to be very popular. I know the 914 motor and tranny seems to be a well used option for em.

 

can you tell me a little more please...

 

What do you want to know? I've answered tons of questions on NICO and a few other boards.

Custom mounts, custom exhaust headers, adapter plate for a Z32 TT transmission.

The car it's going in is a 92 S13 convertible. The weight distribution is WAY off just now. It will be rectified to within 5% by the time I'm done. The VH45 is NOT that heavy. Neither is the tranny. RB20? What a waste. The RB25 isn't much heavier than the KA.

I'm not divulging ALL my secrets yet... but I'll answer questions.

 

well not all VQ30DET's are RWD, the CIMA is FWD.


If you didn't have a 3300lb car, would you really need a big hardcore tranny? You would be fine with the OEM one wouldn't you? A sandrail is about 1100lbs with a body in it, why would you need more? Plus you wouldn't ever have enough traction to chew through an OE one. I think

 

I think you guys are confusing things. Engines are in no way FWD or RWD etc... There's no such thing as a FWD engine. It's the transmission that determines which wheels are turned.

Go to http://www.chrfab.com if you want REAL sandcars. 1300HP TT? MMMMMMMM.

We bought a built N* from them for one of our Fiero projects. We also used a porsche transAXLE. It's virtually the same as a sandcar. FWD gearbox that is inverted to suit a mid-engined format.

 

I think that isn't really 100% true, I think that the engineering behind the engine and the placement of certain things are dependant on the orientation of the engine in the car. makes NO sense to point the TB of an engine right next to the firewall with out enough room to route air into it... for that matter take the whole intake system.

 

Just slap in an SR20DET and call it a day if they 240SX is concerned... Then again it depends on what you're building it to do...

 

The block also determines if it is FWD or RWD. That is why they have to spend so much money on a custom tranny.

 

the block has no FWD or RWD determination...IMO its strictly tranny/bellhousing based. I mean ****, once the flywheel is off, the possibilities are endless... a lot of times from what I've seen block confiuration has little or nothing to do with RWD/FWD, but then again I've only seen a few FWD->RWD(vice versa). seems its simply dependent on engine bay fitment and transmission type...good example I know first hand is the RWD VG30ET motor linking right up with the VG FWD tranny in the 3rd gen Maxima.

 

BOOOORIIIING They're a dime-a-dozen now. I'd at least do a RB25. It's just as easy.

No, thats NOT why they have to spend so much on a tranny. They are running a mid-engined setup with high HP output. THAT's why. It's a big pain to get a good TX thats light, fits in the allotted space, and can take a beating. Try hooking up a normal TX to a highly modified mid-engined LS1 Fiero. Messy Messy.

I like the application of this VQ though. Not many inport powered sandcars. I've seen a lightly modified 4G63T (DSM Turbo inline 4) in a sandcar before. It was nice... but lacked real power.
