V8 Swap in 88 Nissan Pickup

Hey Everyone

I was just thinking about putting a 305 or 350 into my 88 pickup. As anyone done this before??? If so I want to know what to be careful of. I've done engine re and re before but never a complete engine change. Does a V8 even fit in the engine compartment??

Any help would be greatly appreciated

Thanks

Sorry I can't help but I just wanted to say that as a former amatuer wrenchead or backyard mechanic who owned some late 60s/70s muscle cars, your idea put a big grin on my face! A hearty and healthy to ya.

BTW...who not consider a 5.0 Ford. Tons and tons of parts/blocks (long and short) and assorted aftermarket go fast goodies available at very reasonable costs.

they sell motor mounts to do this swap on 4x4parts.com, they say theyre bolt-in. I also think its a good idea, but id go with the 350. theres a few people that have done it on cardomain, if i run across them ill post a link

Well I found this thread so I thought I would bring it out of the dust.

I have finally gotten around to swap a 350 in. I'm in the middle of pulling my Z24 right now.

If anyone cares I'll keep you updated.

The site's name is called Advance Adapters.

Basically, they sell adapters that mounts between certain engines to certain transmissions. I got one that was bought from them for my CJ. As for motor mounts, you'll have to figure out something as I just used 1/4" angle iron.

Hey Nice!

I didnt do any internal work but it's something I'm going to look at probably after air bags.

What I did get for it was Edelbrock Performer Intake, Carter AFB Competition Carb, Holley Fuel Pump, Pro Torque Starter, Edelbrock air cleaner and full dual exhaust with twin Magnaflows.

My other parts were the 15 Gal RCI fuel cell, Stainless braided fuel line, 16" Elec Fan, B&M Star Shifter and Sport Comp Autometer gauges.

I wouldnt mind at some point finding a TBI or fuel injected 350, stroke to 383 and replace the internals with forged.

But even this swap put me well into debt, plus I'm an automotive student, so I'm well in the hole for money...but it's worth it

Great post!!!!

Got a couple questions about the swap. Does it look possible at all to keep a radiator up front? I could go to an electric water pump if I had to gain clearance due to the fan, but Id also want to keep the AC if at all possible. Does it look doable to keep the AC? Are you just using a mechanical fuel pump? Anyway to make the speedo cable work? Did you go to the fuel cell to get away from the stock tank for a reason? I guess you just kept stock manifolds on the Chevy? Also, what about throttle linkage? Fab your own?
Sorry for all of the questions, but I can see in the near future I'll have another vehicle to drive for work so I might consider doing something like youve done. Im almost married to my 90 HB, so a V8 swap would be a fitting mod for it.

Thanks

There are many misconceptions about the Nissan Small Block swap. I'll try to clarify some for peoples reference then get to your questions.

First I just want to say that with right tools, this swap is not overly difficult. It requires cutting, welding, grinding, bolting, drilling, etc... I could do it, with little help from my dad. I have never done a motor swap let alone to a completely new engine.

There is NO firewall modification required for this swap! Which is a huge bonus.

The exhaust (with factory headers) exits at the firewall on one side and mid engine on the other. Both allow for easy exhaust routing underneath without having to somehow run the exhaust through the fenders or go to block hugger headers.

I believe the reason more people dont do this swap compared to the Nissan engines is because they dont think it will fit. Well it wasnt hard to prove them wrong!

Now to Von's questions.

You can go with a front mounted rad, you will just probably need to have one custom made to fit the opening. That wasnt in my budget so I just used the factory one. To have a front mounted rad you will also need a short water pump and the right pullies (PS, AC, Alt, Crankshaft etc) for the short water pump set up. Also an electric fan will be required. You wouldnt need an electric water pump with that set up. I didnt have AC in my truck so I didnt keep it, but I see no reason why it couldnt work.

I have a Holley Mech Fuel pump but an electric one with a pressure regulator would work as well. Again this is budget dependant.

I cant see how to use the stock speedo cable with the GM transmission (doesnt mean it's not possible) so I went to Electric speedo sender with the autometer gauges.

I went with a fuel cell because I would like to airbag my truck eventually and the factory tank makes this difficult. Also Nissan uses a 90 - 0 ohms empty - full fuel sender and after market gauges are usually 0 - 90 ohms empty - full. So using a mech fuel pump wasnt compatible with the Nissan tank. Also it's good to use 3/8" fuel line as opposed to Nissan's 5/16"

I just shortened the Nissan throttle cable and bolted it to my carb throttle linkage.

And like btb03 said the transmissions will bolt up to the nissan transmission x-member, and that positions the engine in the bay perfectly.

If you have any questions feel free to ask or visit
www.nissanminis.com/viewtopic.php?t=44605 for 17 pages of info on the swap Oh and on that site my screen name is iN1554Nt and this truck (2giddyup) was my inspiration and mentor:



And yes that is a over 450 hp supercharged 350 in a Nissan! It runs an 11.2 in the quarter!

My question is how do you harness that power? Did you install a limited slip differential? The axels and driveshaft can take that additional torque? I'd imagine posi traction with that much power would be fun, you could do donuts until you were dizzy enough to puke
