Ive always Said a bpt would be awesome in a Zook. Theres always the bpd aswell which runs a few hot ups to make 156kw. They are awesome little engines easy to get a little more power if u want it and pretty strong. Can have full boost around 2500ish

I've got an Excel with a good 1.5L MPFI engine you can have for $100.

Send me a PM if interested....

I would love to put an excel motor in my sierra which is perfect as I brought it with no engine anyway lol. How hard would it be to mate it to a sierra box? I read somewhere that people run excel boxes in Turbo gtis so surley it can't be that hard. I don't know how true that is but.

[mnemonix]

Definately true about excel boxes in gti's. I've never seen a conversion up close, but there are a few on teamswift/redlinegti.
I think it would be a solid little engine if the gear ratio's suited.
Perhaps not better suited than the squillion other small capacity engines people use though.

so no chance of using the mx5 box or is it to long

Not sure if its too long or not, but it certainly looks that way.

I had read that it used a strange setup that connected it direct to teh diff but I jsut googled some pics and it looks pretty straight forward, dunno how long it is though

[boostedbrick]

stock 5 speed is around 600 long, mx5 box is around 860 long.. Would need to move the transfer to get it to fit.

[607CHA]

What about a shorter jack shaft?

[Fatzook]

607CHA wrote:

That won't get you 260mm though. Maybe 150?

[boostedbrick]

You would have to literally have the two unis back to back. I think there is around 170mm of shaft in between the unis. I don't know if this would be the best idea. And not short enough...

[607CHA]

Moving the transfer back would put the uni's on a big angle for the tailshaft though. Not sure how strong the boxes are in them though.

Great motor. I had an NB8B NA a few years back. Crashed it...badly .

I proved on a dyno, with a simple intake I made up, the power went from 64rwkw to 78rwkw. Can't remember what the torque figures were but it picked up around 15nm as well.

If you were lucky enough to have purchased a turbo model, for $3100 you could have yourself 145rwkw or for $5500 you would have around 165rwkw. This is completely reliable power too.

Gets me thinking would one of these motors work in a Vit?

Better than a SR20DET i would imagine.

[kirstyandgrace]

I currently own a 2001 mx5 and a 1992 sierra.
Without measuring there is no way the motor and gear box would fit.

There is no way in hell you would want that engine and gear box combination in a sierra.

The mx5 is a pretty light car and is capable of 200+ km / hour. The sierra is lighter, doesn't quite have the same suspension geometry and a little less aerodynamic. I'd imagine it ending in tears pretty quickly

[607CHA]

Standard mx5 does come with a transfer case that can have 6.5's good luck getting to 200kmh with 6.5's

[boostedbrick]

Mx5 weighs around 950kg, not much less than most sierras.

1st 3.136
2nd 1.888
3rd 1.330
4th 1.000
5th 0.814

WT
1st 3.650
2nd 1.946
3rd 1.422
4th 1.000
5th 0.793

I think with the right transfer and diff ratios it should work well...

Anyone have AW4 ratios handy?

How would we go about calculating the gear ratios? is there meant to be a specific ratio sierra's tend to like to run on? i've currently got a toyota 5k engine in mine and it goes like crap and i hate going uphills with it as fuel keeps cutting out.

Maybe if i can persuade my friend to help me out i'll be up for having a go at it

I'm very keen also.
being a 1.5l It stays within the 15% engine increase, so i dont think i would need to engineer it.

mnemonix you wrote in another thread that the twin cam isnt as good as other engines which i assume your referring to the single cam engine. why is that? i loved the twin cam engine in my excel.

Maybe something is wrong with your carb? My bog stock 4k pulls up hills in 4th with a rat shit carb.

Sorry off topic.

[Gwagensteve]

Grimbo had a LWB with a 5K in it and it certainly had plenty of power.

[anDy86]

Jackson & Gwagensteve - not quite sure why its running so crap then.

So i have done a google search on gearbox ratios for the Hyundai Excel and got these figures and copied boostedbrick's WT figures:

1st 3.462
2nd 2.053
3rd 1.37
4th 1.031
5th 0.838
Final Drive 3.842

WT
1st 3.650
2nd 1.946
3rd 1.422
4th 1.000
5th 0.793

I really don't know if the gear ratio's match well as i don't know how to calculate them.
Is anyone kind/bored enough to tell me if these will do the job?

[Jasen]

It's no good looking at gear ratios of the excel box as it's an East-West front wheel drive box. You'd have to mate it to another RWD box with an adapter most likely.

[jimbo_jones]

Built4thrashing wrote:

yeah but what box would you mate it 2?

[Gwagensteve]

Which brings me to one of the things that I think sometimes get missed when talking about engine conversions for a 4WD.

The engine we want to use is only as good as the gearbox/transfer you can mate it to. It's one of the reasons the G16B is a good choice - they already come attached to a reliable 5 speed manual or reliable 3 or 4 speed auto in RWD, short-output configuration.

It's easy to see how you could end up with more money in the adapter, torque converter and flexplate alone converting, say, an excel motor to RWD/auto than a whole G16B conversion.

Another example - 4AGE's are great motors blighted by terrible gearboxes in a 4WD application - a weak manual, a strong but hard to get manual, and a weak auto, all really long. I'm sure Dank has probably dropped more coin in sorting the auto behind his 20V than he paid for the 20V motor.

The feasibility of the Mazda BP conversion is all about finding an AW-4 bellhousing from a Miata. Achieve that, and the rest of the conversion is easily achieved.

Steve.
