Quad throttlebodies

[Grunter]

As some of you may have read in a differnt thread,
I am toying with the idea of swaping my inlet manifold to one off a GTiR Pulsar/Sunny, Has any one else done this or looked into it ???

Why not just swap the whole head of a SSS Sentra/bluebird. (I think they both use the same version of the sr20de.
Then you get the right sized throttle bodies for the 2.0l, as well the cams and head porting to make the most use of them.

Of course if you have a 1.8l primera I wouldn't bother doing anything to the engine. Just stick with haveing the best looking Primera Iv seen (sorry p-man) and work towards a det swap.

It is a 2L , and we where planing on getting some cams ground up to match the new inlet, with maybe a air/feul control to finish it off.

I know i shouldn't of gone out to the drags becouse now i need
MORE POWER

Thought about fitting the SR20VE head? So far no-one has tried it but your freinds at Turbo Technology may be able to do it.

hahaha! a comon problem!

Cams are a must if you want to actualy make any more useable power with the quads.
It might pay to check if they will flow enough air at the right velocity to feed the SR20. 200cc donst sound like much of a differnce, but it could be enough to mean you may lose power.
Find a good local shop with a flowbench and give them all the specs for your motor, I cant imagine it would cost much.
If your Auckland based then Leading Edge cylinder heads are the best, their based in East Tamiki, numbers in the book. They will also be able to flow the head and make any changes to the ports that may be required, as well as recomend a good cam profile. (aparently anything to wild upsets the valve train on the SR20s so be carefull here).

It may of course be possible that the quads will bolt up with no troubles, but I would find someone who has done it first and found out if it will work before trying it with out doing any hard resurch first.

And have you checked on the price? the GT-i motor is worthless with out the throttle bodies, so wreackers may not be prepared to seperate them.
e.g. going rate for quad throttle bodies from a 20valve 4age is $1,000, or the same as the cost of the motor.

The only prob about the VVT is the computer would be completly differnt,
I not a fan on v-tec and mivecs (my g/freind has a mirage cyborg, and i have a couple of freinds with v-tec) and i hate the dead spot down low

I know of a complete VVT engine for sale in NZ at the moment if you where keen ????????? It even has the tiptronic m6 trans on the end of it.

what dead spot down low? the early VTEC's, and less developed Mivacs have a flat spot in the middle where the cam changes over.

I take it the SR20Ve is the bigger brother to the SR16ve? with the variable cam profiles, and cam timing?
Where in NZ is the motor? and what model Primera did they come in? Iv only ever heard about this engine, but never seen one.

I can get the quad thottle body set up for $400
or a complete GTiR engine (minus intercooler) with stuffed bottom end for $1000, and off that i could sell the turbo for about $350 and keep the mainifold just i case (if you get my drift) and it still leaves me with a head to sell, plus lots of little bits and peices.

There are quite a few in NZ in station wagon fourm, some are tiptronic others are just cvt trans,
the place that i know have one is out of a s/wagon
G & M Auto Spares, Bond Rd, Te Awamutu, ph 0-7-871 8575
Im not sure what sort of money they would want for it though

The charts I have seen show the torque/power of the VE engine is superior right across the rev range. The stock VE (compared with the 110kW SR20DE) makes something like 20% more power at low revs, 10% more midrange and 20% more at high revs. This is all due to the higher and flatter torque curve throughout the range.

Just out of curiosity, whats that engine selling for? Not really interested in the CVT.

DOH! you posted while I was typing.:o

ahhhhhhhh! yes Iv seen them. everyone raves on about Audi making a CVT that could handle a lot of torque, but dosnt know that Nissan did it first. (another japanese first that no one recognises).

Te awamututu is a little far from here but im heading to toupo in a few weeks, I might drop in on the way down and have a look at it. What sort of hp?


Thier still slower than my civic though!!! (and you thought I wasn't going to say anything!!!!!!!! )

[T4 Primera]

They make 19hp around 7000 revs. That doesn't tell the whole story though - what really makes the engine is there is more power available earlier in the revs and the torque curve is flat from about 4.5k thru to redline. I'll see if I can dig up a chart ...

[T4 Primera]

Here's the torque curve.

This should provide everyone with a great visual description.
