Engine and Transmission Rebuild and Swap

Post by **Q45CALIBER** » Tue Mar 28, 2006 9:11 am

I am considering taking on a project. I want to remove the old engine and transmission from my Green Q. The engine was running just needed gaskets and some care... when I started removing parts form the car and the transmission was fine.

The engine I would like to send to a shop for a rebuild. The transmission I would like to swap to transmission shop for a 93 core rebuild. If I take on this project I need to establish a few things to understand the scope, price and time I will be working with.

1) With the old engine (green Q) what exactly can I do to harness the most NA power and efficiency. I would like to increase the power and torque. I’d say at least to add 80 horses.

Chain GuidesPort and Polish HeadsPort the Intakevalve springs.Rocker arms and lifters (orings) Cam sprocket5mm overboreHosesseals (crank)HeadersValves?Bearings?Rods?

2) With the old transmission (easier concept for me) maybe Jamesmost can help....would the transmission shop take this core for a swap on a 93. And exactly what rebuild is recommended.

I am trying to get a guy to come over and remove the engine and transmission this weekend. I would like to get started. Or at least ship the engine to the shop. I want to be able to tell the mechanic exactly what I what him to do.

Also price wise with just parts what am I looking at?

ThanksCali

The first thing thats most important, what year is the green Q?

Generally if you were to supply a core, they will rebuild that core..... If the trans is working, id sell it as a working trans and the buy a 90-93 core for rebuild....

You wont add 80HP N/A.. its not going to happen... you basically want around 380 FWHP, and with 6lbs of boost, your barely getting 400FWHP...

IMO if you want that kind of power, you can get my SC for around 3500, bolt it on, and have around 400HP... if you had headers, thatd only make it better. youll spend a TON of money on all that crap you listed.. Not to mention, if you start changing things big time, your going have to change things in the ECU.....

The fact is that everything you listed doesnt exist which would mean itd have to be custom, or it simply wont do anything.

I dont see the port and polish doing anything! Would be nice to have it nice and clean, but other than that, i dont see any gains there...

Ill be glad to go into more detail, but if your engine is form a 90-93 it wont realy matter since it wont go right inot the 94 anyway.

What the hell, im feeling kinda chatty today so ill just keep rambling.....

To answer your question on how much all that stuff would cost, i have no idea, but id say if you wanted to do ALL that stuff CORRECTLY to OEM tolerances, youd easily be looking over 10 large... I see it going higher than that, but id say thatd bea pretty nice estimate... Custom stuff like that for an engine THAT DOESNT REALLY NEED ALL THAT STUFF is expensive!

Remember the VH45 is basically a racing engine detuned for a luxury car!

My honest opinion would be to do hte following: Assuming the engine is worth saving, just take it apart, clean it real good and inspect things... I think about as far as id go is replacing rod bearings nad rings.... HOWEVER, if your not doing the labor yourself, your still better off buying a JDM takeout thats going to be in better shape, clean it up nice, install new rubber, KS and check everything else...

REmember that JDM takeouts are only about 1500 at worst!

And what makes that "at worst" is there is no allowance for rehabilitation.

Are you feeling lucky, Gaijin?

Im talking just to buy the engine! OF COURSE it is ASSUMED that you will replace all hoses and stuff anyway, as he was planningon doing this anyway!

AT WORST you can find a DECENT used takeout that will need only basic stuff (KS, hoses, maybe an injector or two, spark plugs, reseal, and a thorough cleaning)

My Green Q is a 94 I have been slowly removing parts from it as needed. Noting big just KS, Air Condition Compressor, Tenioners.

Wow I guess it is not really worth it being I have a completely good engine with 133,000 on it. Driven by a lady in here 60's in Connecticut

Thought it would be a good project but is seems like it would be a cash drainer for minimal results. I guess I will just part the car out and use some of the mods that we have here on NICO for improving performance.

I am sure that engine as about another 100,000 miles on if treated well. I just get so stoked when I watch spike TV on Sundays. I get rebuild happy.

I think I am going to take your advise and pull the tyranny and sell or see If I can swap since it was working perfectly good. I just needed a Black on Black Q in my life.

My black Q is my third Q. I first had a Y33 Burgundy T model. I was making payments on it and found that I was more impressed with the G50 performance after a friend smoked me in a race. The rest was history.

A Y33 owner sees the light

if your engine only has 130k and its in good shape, then you might as well save it and you could try rebuilding it over the course of a few years, and have an engine ready to go in.....

What might be easier... what are you wanting to get out of the car?? Why not just go with the SC?

I WANT TO. But everyone projects seem to have been cut short. I have been in the post but I have not seen the final projects and feed back.. I was about to get a eaton 112 and have a local shop put together a custom setup for me but not enough data on the other projects.

AZ's project I dont know what happened with it and there are a few others.

Post by **elwesso** » Wed Mar 29, 2006 2:45 pm

what do you mean, my SC setup with the eaton M90 is already proven!

Wes, what happened to the burgundy engine that you shipped off, to use as a template for the SC. Has that been done?

Where do I send my $3,500.00, and when will I get my SC?

WHy don't you buy Cali's low mileage engine, and mount the SC to it?

You could use it as a working test stand engine, to put on a dyno.

ooh i must of missed that topic. I though yours was on the incomplete list too. Damn I missed out. How come there isnt much talk. I am excited damn.... why isnt everyone jumping on this. What is the gas milage like and the gains? Can you refer a post?

Sorry I got alittle hype.

the engine is in FL and all someone has to do is send a deposit... Its ready to go..... ITs just used to develop the SC, there will be NO TUNING as far as like dyno tuning done.....

Turnraound time is about 2-3months for the first kit...

if your SERIOUS, contact me, and ill tlak to you till your blue in the face.

I suppose its not technically complete, but all the development is done, it just has to be built.....

I have never understood why people don't just develop a light duty Nitrous system [less than the 75HP shot JWT] that would be much less stressful, less expensive in use.Especially with the current ability to add a dual mode WOT program to modded ecu.

A 25 HP jet [at 6,000 rpm] would yield 60+ lb/feet at 2500 rpm progressively decreasing to30>25,

This would surely solve the 2nd gear weakness from 25-50 mph. not burn the tires off at launch and the tank would last 3-4 times longer between refills.

Not effect the optimal 2nd gear quarter mile like a 4.083 does assumming redline was raised to 7300 and yield a 14.6-14.8/97-98 with good tires.

With a little tweeking we might SLOWLY!!! get a system to 14.4/99-100 to match the new M45.Without exhaust mods or cone filters. Tires would be the key in the lower ET and maybe a 35-40 shot.

Post by **maxnix** » Thu Mar 30, 2006 6:15 am

Yeah, for a one shot deal, nitrous is OK.

But it is like a drug. You run out and it's not always there, and it can't be used continuously.

Post by **Q45tech** » Thu Mar 30, 2006 7:37 am

Soon we'll all be required to refine our own gasoline [to remove ethanol and add aromatics], so why not make nitrous compress it and fill the tank once ever 2 weeks.

A 75 shot uses 1 pound per 15 seconds so with 15 pound tank you can do 15 quarter mile runs per fill.The system I propose would get 45 runs or 11 minutes worth.

Most off the self systems are very wasteful and not optimized.

Thats a very good idea tech... However, IMO, youd be better off and easier to do the high stall torque converter (BILLET) and/or the 4.08.....

I dont have much of a dead spot in my Q with the ECU/3.54 gears/high stall.. not NEARLY as bad as stock.

Post by **Q45tech** » Thu Mar 30, 2006 7:52 am

I assume $60 per 15 pounds and of course the time and mileage to get to and from the refill station.

How many times per week are you going to drag an M45 or the like..........gets boring after awhile and the word spreads.

You install a timing accumulator so you know how much you have.

Gives a nice buzz as well. Sort of like smoking pot. Not sure what it does to your brain cells but I used to enjoy going to my dentist when he was using NOX.
