After reading the stickie, it seemed pretty interesting. 11:1 CR and 3.3L.

I would be putting this in my S13 not my 3rd gen.

Also this would just hold me off untill I could get build a turbo setup for a VQ30, or build a high compression VQ35. The VQ33 was acttractive because it would give a mildly high power engine with just a couple hundred bucks. I figred $400 for a DEK, then $800-900 for a 3.5L. Thats all the stickie had for info any way, and the pics didn't work.

Any way if you guys have heard anything since the last thead died off, that'd be cool.

i got my vq35 for $500

 

VQ33= Waste of time, money and effort.

Besides, do you honestly think you can put one together for less than the cost of a VQ35?

 

Exactly. The effort and money spent could have a VQ35 sitting in the same engine bay.

 

But which one would have more power? I know Id have to buy at least the crank and rods of the VQ35, and might as well get a whole engine. But Im just wondering if the VQ33 would make more power untill I could get some mods for the VQ35.

what parts would you be using from either engine?

 

Id use a full DEK with the 3.5L crank and rods. Other then that the 3L heads and dek VI. Thats all I know from reading the sitcky any way. Id be using megasquirt for engine management so tuning would be easy. Perfect ARF and as much timing as I want. So thats not an issue.

Im just seeing if its possible for the VQ33 to make more power then either the VQ30 or VQ35 by just using the VQ35 rods and crank. This is just a temporary engine any way, as Ill be going build NA VQ35 or Boosted VQ30.

Feel free to prove me wrong.

 

The slight increase in compression will not be enough to counteract decrease in displacement (3.5 to 3.3L) to make this worthwhile imho... I think you could make more power with just a stock compression 3.5.

 

I seriously doubt a DEK head will outflow a stock VQ35 head.

 

you're going completely out of your way for minimal gains.

I might be wrong, but i though 3L heads and 3.5 liter bottom end yielded lower compression, which was ideal for boosted applications. I wouldnt spend this much time on a "temporary engine".

megasquirt won't run on the VQ ignition system, you'll have to get rid of the coilpacks.

 

Actually the MS will run Coil over plugs. You get ford's EDIS-6 and then modify it. and If I decide to not run the COP's I can just use a plain EDIS-6 and sell the COP's.

The engine Im making is a VQ33, a 3L block, heads, and piston, and a 3.5L crank and rods. The 3.5L crank gives a longer stroke, and the rods are shorter so the pistons wont hit the heads.

A VQ32 is what tilly has made, and it uses a full VQ35, but with 3L crank and maybe rods Idk about that one. The 3.2L is the low compression/hi rev one. the 3.3L is the lower rev but higher compression.

the VQ32 is around 9.5:1 and the VQ33 is about 11:1 the only negative to the VQ33 is it doenst like to rev as much as the VQ30.

The only thing I want to know is if the VQ33 will make more power then the VQ35. Maybe I can talk to tilly. He should have some VQ35 parts laying around from building the VQ32's.

Still, way too much work for a temporary engine that most likely wouldnt make more power than a stock VQ35.

 

It won't. But I hope you go ahead and learn this lesson the hard way to prove it to everyone else.

 

Are you going to mill the pistons or run a thicker head gasket to clear the head?

 

Just get a cheap junkyard VQ35 and call it a day. You can run 13's on street tires all day for maybe one grand and you'll have a reliable, factory assembled engine, not some shot-in-the-dark hybrid nobody has even tried.

You want to be original? Buy a VQ40 and get a tranny adaptor plate machined.

 

Yea it does sound like too much work for being unproven.

Guess Ill have to get a VQ35 after all....

VQ40? Naw Id rather no have to make a new hood and use some rev's to make power any way. Would be pretty cool though.

oh man
