Engine Swap Forum

Fred Allen Burge:

That's funny!  I'm suprised it's taken this long to meet someone local actually.  Come by any time if you like, i keep the car there (it's in a pretty embarassing state right now though, not much to look at!).  I usually take lunch at 11 and work some Saturdays until about noon.

 

BTW, if anyone wants to talk on MSN Messenger I'm usually on there, you can add me with turbosforsale(at)hotmail.com

My parents live in Springfield... next time my family is there I may have to come check this out. It'll be summertime probably, so I'm sure you'll have it running by then.

Looks like you guys have an I30t that may be a perfect candidate for this.

Did I see that you sold the motorset Fred?  Whats the deal with that?  You tricking us all and going with a pre-production GT-R powertrain?

Geeeeez that would be hot.  Hell, even an HR would be a great thing to see in a 240...wait a minute, that might be the next project?!

It is for sale, I just need some cash right now and the car needs lots of work other than the motor (body and interior) so I'll focus on that stuff until it's done, then get another motor package put togther at that time, no biggie really, project is still "on" just in a different stage. 

I'm actually leaning towards a VQ30 w/ 3.5L heads and two small turbos (WRX, VW 1.8t units, maybe Saab turbos...) but we'll see, I've got plenty time to think about that. 

 

Can I use stock VQ30 pistons with the 3.5L heads?  What does that do to compression ratio?

Spoken like a true DIY'er.

(Yes, he explained the whole selling of the motor thing to me. That's why I'm not giving him hell).

Apparently, even with all the excellent engineering that will go into making the GTR a safe car to drive, GTR owners will end up driving the most dangerous car ever built. 1) As with most other supercars, ppl do the stupidest things to try get u to race & 2) There'll be a host of DIY'ers/ engineswappers trying to run them off the road to try get the GTR engine...

Argh... guess I'll stick w/ the plan...

Yes you can use the Stock 3.0L pistons with the heads but shave them about 40 thou to bring up the compression for NA or leave them for turbo set up. It is a snappy set up NA though if you do it right.

Ok thanks.  What factory cams and sprockets do you use with that combo?

The quench area of the 35 heads is hurt when bolted to a 30 block.  I'm not really sure why though.  I'm not supplying this info from personal experience.  Its what I've read on the .org from some of the knowledgable memebers(Looking for post evidence now).  Perhaps Drew has some insight to this.  My thinking is that in NA form the flemished quench pads are not a huge problem.  But with boost I can only imagine. 

The 35 block, if for no other reason, is superior for boost due to its OEM piston squirters.  That alone is enough of a reason for me to go with the 35.

30 cams can be used but will not fully utilize the heads.  35 cams can be used but must have the dowel pin redrilled.  30 sprockets work just fine.

 

Good call on the GTR's Kurt.  First one I see, after I piss myself I'm gonna ram into the back of em.  J/K.

THAT IS IF YOU CAN CATCH HIM TO RAM HIM!!!! HEHEHE.

The ideal turbo set up as far as NISMO are concerned is the 3.0L block with the 3.5L heads. For me the 350Z heads shaved at 40 thou bolted right up to the 3.0L block we use the 350Z cams and sprockets at first then switched to the nismo grand am race cams. We used the 3.0L front cover. Again if you are doing a twin turbo set up put the heads straight on the 3.0L block. Can the squirters be swapped??

Drew

The oil passageway doesn't go down there on a 30.  I guess you could do some figureing and drill your way up to the stock passage but that'd be b!tchy.

U could try strategically placing a pinhole in ur rods too...

I can't claim to be the first at this nor do I care to I just wanna be one of those who has. You think this swap is possible in a s13( 92 240sx)

Nope, not possible in an S13...  :sarcasm of course:

Correct me if I"m wrong, but I believe the VQ30DET has oil squirters too...

S13 Fastback...putting the chassis together.

Suspension before power!

yes it definatly does ive seen them with my own eyes.

so i should be on the lookout for a pair of 350z heads?
