rb25det....Q45......

[Andreswithag20]

This might already be in here but I couldnt find it. I got a 94 Q45.....I got it for $1300 in real bad shape but I've been restoring it. The interior has been redone (the wood is real, no stickers), got a body kit (JP), all dents have been removed, lights replaced, new speakers and subs plus in dash "carputer", keyless doorhandles (from donor back doors), center tailight peice shaved off, rims, all it still needs is paint (it's been sanded and primered). The dilema......I'm ditching the V8. It has injector trouble and no after market support plus I want manual. I dunno if I should swap in RB25det or RB26dett, I dont need 1000000hp just 500- 650hp. I wanna go with rb25 cuz it's cheaper and can still get the power I want plus it is more smooth and comfortable but it doesnt have as much aftermarket support as the rb26. My biggest worry is that if I swap the skyline engine in I might lose some of my cars functions like AC, climate control, and other car functions....also dont want the computers screwing up. I also dont wanna sacrifice the cars stock guages with ugly sport ones that wont even match.

Swap in a 351W ford motor with aftermarket alum heads and you can get 500+hp without much effort. It's pretty light too. Should be about the same weight as the VH45 when all is done. If you get a 351W to build and it needs rods or a crankshaft, get the cast crank 427 stroker kit. 7 liters is a good engine for this heavy of a car. Back it up with a Tremec TKO600 manual trans and you'd have a stout and reliable combo. The factory tach would hook up directly to the 351W distributor and you can probably get adapter fittings to put the temp sensor and oil pressure sensor on it as well. It's a front sump oil pan so that'll work great also. As for A/C, that won't be easy unless you make a bracket to swap the factory Q compressor to the ford engine. Same with the alternator. However, a ford 3G alternator (found on '94+ mustangs) can be wired for 1 wire hookup and is 130 amp. Power steering lines will need to be made to use a ford pump with the Q rack, but should be cheap (just take in the ends and have them stuck in the hose of correct length in the right position and the shop can crimp it together). Or you could make a bracket to keep the Q steering pump. If you want to do a turboed engine, a low compression 351W can be cheaply built to reliably make over 800hp and 800 ft/lbs with a T76 or slightly larger turbo (or a pair of 60mm turbos if you wanna go with twins).

all i can say is from driving my car is i love it. words cant explane how it makes me feel. mines a lil too hard core for DD but i i love it either way.

There is no way in hell I'm tainting my beautiful Infiniti with a ford (or any engine other than Nissan/Infiniti)

[Andreswithag20]

I'm definatley getting RB but I just don't know which engine 25 or 26......my biggest fear is that the computers are gonna screw up or AC and guages wont work.

[Q_SHIP]

Welcome Waukesha!!

Injectors are simple issues on the 4.5. Miles??

[ScottJackson]

"tainting" it with a Ford? Obviously uneducated and biased opinions have already been formed. Good luck!

Hold on while I ROFL sarcastically for an hour or two.

[Andreswithag20]

Dude, why are you getting hostile? Did you even read what I said? I'm not dissing ford, I'm a purist and I think it's ugly and taky to cross cars like that especially on premium classy cars. I dont care if it's a Lamborghini v12, Nissan engines go in Nissan cars. So, if I'm so uneducated and biased....what do you think of the Mustang with RB swap from F&F3?

[Andreswithag20]

Anyway....back on track I talked to a shop here in Wisconsin (PAPES) he said it can be done and I can keep all my functions and guages exept for traction control and cruise control obviously. Now if I get the 25 it comes with RWD transmission but if I get 26 I need a separate transmission....it's a tough call what is the max achieveble power, do they sound similar, emissions, after market......ect. Thanks

[Q_SHIP]

Whereare you in waukesha? That was my stomping grounds. Im in Mukwonago now. Tons of friends in waukesha.

I'm with you. There is no way a ford engine would go in my Q car.

[elwesso]

I stay keep it on equal playing fields. I agree, im not going to downgrade to a ford motor into a Q45.

Personally I would say that an RB would be a slight downgrade or a level move from the VH45. I think most learned people would as well.

[ScottJackson]

While I doubt I'll every agree that it's a downgrade to go with the ford V8 (not a huge fan of the Lambo 12s either), I was mainly suggesting an affordable and simple way to get the best HP and torque for a heavy car. I think a drifting car, especially of this weight, could certainly use 500+ft/lbs of torque and almost that much by 2000rpm. I don't know how easy that'll be with a 2.5Liter engine. It's just my opinion that if you're going to take the effort of doing a swap like this, may as well go for bang for the buck. Otherwise, I'd probably just add a remote mount turbo to the VH45. I still say the Holset HY 35 off the dodge cummins 5.9 would do a great job. On 3.8L mustang V6's they hit full boost by 2000rpm. Use a big wastegate and it should spool quickly while also not choking up the exhaust with its small hot side. That single turbo is good to over 500hp at the flywheel and can be bought in good condition off ebay for about $250. I personally have never heard of a motor that cared about what name was on the valve cover. I look at the traits of any engine and use that to decide what's best for a given application. To each their own, though. EDIT: I see that the original poster wasn't going for a drift application, just the one example of this swap was into a drift car. I guess if you don't want the low end torque and reliability that comes with a bigger motor, it won't matter what gets put in there.

[midnightsliding]

How are bigger engines more reliable? anything with a good tune is reliable. theirs RB's out their making 700whp on stock block's no giving i don't know alot about the VH and im into learning more about them, but from talking to slim a while back he said something about the VH having small water jackets and not being about to cool higher HP applications so for drifting thats y i chose the RB b/c of its proven back ground and after market support.

[ScottJackson]

It's a generalization that a bigger engine will be more reliable than a smaller one at a given power level. Of course cubic dollars can influence that a BUNCH. If you can get the power of a 20psi boosted 2.5L motor with 6 liters non-boosted, you'll usually have a much easier time getting it tuned right and you don't need all the plumbing and parts associated with a turbo system. Less parts means less chance of failure. Isn't engine braking good to have in drifting also? A big motor will have more effect when letting off the throttle than a smaller one. Aftermarket support definately matters too. I wish there were cheap tall deck aftermarket blocks along with stroker cranks and camshafts for the VH45. I think one stroked to around 6-7 liters would be great. I suppose I could get deck plates made to make it taller deck and then get the crankshaft rod journals spray welded and offset ground for a longer stroke. Then I could get some rods and custom pistons to work with it. By the time you consider the cost of that along with a custom intake and timing chains and the 8 cylinder sleeves to make it a tall deck, it's not worth it. There's a lot of aftermarket support for the small block ford too and it makes it cheap to get big power. I don't have anything against small chevies either except the rear sump oil pan won't fit the Q. The LSx chevy V8s would fit and have lots of aftermarket support. It's almost shocking how much chevy copied the small block ford with the LS1 (port layout, rocker arm ratio, front oil pump, firing order...). I haven't heard of this cooling issue with the VH45. Where's the Aussies that have hotrodded this motor to chime in on it?

When can we expect some video of your Q midnight? I didn't even know that was in the works and now ride of the month! Looks very awesome!

[midnightsliding]

u have to turn the volume up to get the full effect hahahttp://youtube.com/watch?v=sG83quae658

[Q_SHIP]

Why is the vid named "MB drift"? Do people think it's a benz?

[midnightsliding]

no thats the name of the venue Myrtle Beach South Carolina.....it sucks b/c i was only full throttle coming out of the gate and the rest of the course was no higher then 4500 RPMs, witch is not even the full glory of the powerband. theirs an event coming up Feb 3rd their claiming high speed entries cant wait, hope the car gets out of paint and new drive train set up is back in.

[KoukiS14]

You live in Winston - Salem? My parents live in Jamestown -- I'll have to stalk you next time I'm out there!!

[qsiguy]

That is awesome midnight! I want more footage tho. Very cool!

[midnightsliding]

yes well i live in kernersville but not many ppl know where that is so i go to the biggest city next to it.

yeah more videos to come hoping to get it out to another drift event soon.
