Engine swap
 

I've been looking at options for turbocharging the 370z, but I would need to get a whole new engine block for the power levels I want to achieve. On the gtm website it says that a 4.5 liter stroker engine would be needed for 700rwhp and I was thinking why not just put a different engine that would be cheaper to modify. Would there be any good engine to fit in there and I am thinking V8 or a more race ready engine like an rb26dett. Would this also solve cooling issues?

What kind of power do you want to make?

My engine swap would be the new VK56VD. :tup:

Just slap a Super charger on

To easy. :tiphat:

Why do you need a stroker kit for 700whp? You can build up your existing 3.7L bottom end and achieve 700whp with the right turbos.

I too have been wanting more power. I would like to go FI but am worried about longevity issues and wondering why you don't see more people strengthening the bottom end. It seems it would be cheaper to do swap with an engine that already has 450 to 500 hp than it would be to FI the VQ and hope for the best.

Will it fit?

Don't know.

"when there is a will, there is a way"

Why spend another $40-grand or more modding the 370Z - just go buy an R35 ............ professional engineers have already solved all the problems - unless of course you want to throw your hard-earned at a shop that will already be salivating at the amount of money they can gouge out of you !!

Its the sleeper factor.

same reason why its fun to build a GTR that can burn a bugati veryron. Its fun to build a car that is faster than cars that should be faster than it.

Well the 3.7L is "newer" and people are going to throw forced induction on first, slowly build up the boost and find the limits of this engine and then start building it out. I would love to build the motor and TT/SC, but one thing at a time.

370z TT pay close attention to my build in the FI thread since I am the first to build the motor and TT. Expect to pay $13k+ for just the motor alone if your going the same route as me. Feel free to ask questions in my thread as well and Sam can answer ur questions.

it wouldn't take 13k to build the bottom end. it takes that amount of cash to stroke the bottom end. you don't need the stroke and bore to get that kind of power it just makes it easier. you would need new pistons and rods, lot's of studs, some port work, and some properly sized properly large turbo's. you could probably get away with it on the stock block without sleeving it but sleeves would make the engine last a lot longer and if you went sleeved in the future you would need different pistons anyway. you could probably have a sleeved built block for 7-8k the parts would cost you 5-6 and then another 2-3 for labor. add another 10-11k for a proper turbo kit and some extras, and you would be looking at around 20k if you price hunted, looked for deals, and had some connections/knew how to put it together yourself.

People with the old 350Z DE motors are putting down well North of 700whp on a basic built bottom end, 272 cams, and STOCK heads. You do not NEED a 13k engine. Unless you just want to be able to say you have a 450Z.

An engine swap is nice, but the VQ37 already is a great engine to build upon it would be a waste to put something else in. Turbo or supercharger is a nice way to boost the power, and you are able too stay in a safe range for the engine.

+1 Amen. Alot of these builds are seeming more like bragging rights/publicity stunt builds.

I can't wait to see true 370z setups with 750-850 whp range. Or in the alternative, some nice all motor builds...Hmmmmmm.

Just as a disclaimer... When I said he would need a 13k+ motor that was in reference to him wanting the 4.5l stroker like he originally stated. I agree with you guys if he just wants 700hp I believe a regular built bottom end should accomplish that. 370z tt your best bet is to call Sam over at GTM and ask him. I can't stress to you how helpful and knowledgable Sam is. Sam has helped me design my entire build.

Mine has a specific goal! Kick a Veyron's @ss!!!!

Puts alot of things in perspective. Goes to show that sometimes having x amount of whp doesn't mean crap.

Switzer Nissan GTR smokes Bugatti Veyron

Dude he has a nitrous oxide system! There is no way his max hp was 720hp. He was being walked on in the second race then BAM!!! NOS and he freaking walked on the Veyron like it was a civic!

The Veyron is a fat pig... it would get its *** kicked in a straight line by any 750+ WHP Evo or Z. The GTR is also very hefty at 3800 lb or so, but nothing near the 4500 lb of the Veyron.

That said, the Veyron is an amazing car. They couldn't have built it like it is without having it weigh 4000+ lb.

^^ holy...........

Gotcha ;)

I can't wait to see what kind of numbers you guys can pull off, it looks like a pretty sick build!

Thanks chris! Yeah I can't wait either lol wish I had my baby right now!

yup veyrons are heavy hell they weigh just a bit more than a dodge challenger which is why the challenger is so freakin slow for having 425 horsepower.

I'm leaning toward a N/A sleeved and built 3.7l. I applaud bullit for the stroker but I figure that since Nissan gave us a tach that goes to 9K I might as well find a way to get it there. However, it's going to be awhile before an efficient and experienced build is possible. You could always take it to guys that have built 350z but they'll want to sell you a long block. I'm sure someone will pull the trigger in due time.

Does anyone think are heads are up to it? Heads are very expensive and if the OEM heads are up to it that would be awesome.

you will have to build the heads for that high of an RPM range and probably go to ti valves to free up some weight of the valves.Mine is getting a head job do to it. A N/A build will surely have to have the same. In all honesty a long block would probably be your best bet.

Anyone actually tried any of these:
