Hi i havnt been on here for a few months and have been thinking.

How hard would it be to fit an sr20 into a UC?

The UC is lighter than an s13 (just) so it would go well.
My uc gas all wheel discs and 6 cyl suspenion so that would be ok.

So what would i have to consider to do it as ive said many times i dont have a lot of money so could it be done cheap ( so to speak). I know engine mounts, gearbox mounts and wiring are to consider. But does anyone know if a custom sump would be needed? Could it be mounted so only the tailshaft yolk needs to be changed rather than geting a new one made to save money?

What would an overall rough cost be i know i could get a motor and box for under $1000 if i shop around but could i use the cable clutch?

With the wiring all i care about at first would be getting it running and driving gauges and so on could ve done later on as long as i have a speedo.

Again its just an idea ive had recently. Is it possible on a low budget?
What other things are there to consider. And is it too big of a job?

i doubt the brakes would be up to the task? and it would sound like a wet fart   and i agree with mark, if your going to the effort of the engine swap may aswell go with an rb or even a 1 or 2jz. 

 

not to put you off, but i dont think it would be a low budget job if you cant do 99.9% of it yourself

For the fuel system couldnt i just add a electric pump outside the standard tank?

For the diff ratio i have a 3.9 and a 3.08 here so one should surely work with the combo.

As for a turbo it wouldnt get one to start with as ive still got 18 months on my p pkates but it would be a future option.

The larger 6 rb is heavier, longer and more expensive, plus when you can get 400 hp out of an sr why go the heavier motor for the same power as thats the max i would want. And with how light it would be with the sr block it would probably pull harder than a standard s13 too

rb30's can be had for as little as 1-200 bucks, cheaper than old holden 6's

[Ice]

Not to put you off either but sounds expensive to me and i by no means an expect on those conversion
have done 6 to 8 before which would be cheaper

[hawk]

I can get an rb30 manual with loom,fuel pump and turbo setup for 1k but ive heard the conversion gear by crs like sump and engine mounts arnt the best. Do you think a conversion is possible for say 3 - 4k? As if its more than that i dont know if i could afford it or keep up motivation to get it done.

[hawk]

Ive just had a look at a few topics and it seems crs stuff wont really work and the motor fouls in a few places with the sr being a lot smaller wouldnt that eliminate that problem?

The main reason im asking about conversions is because im sick of the problems ive had with 202's and weak gearboxes. I want something better on fuel and more reliable as i drive from albury to melbourne quite often. I also have my first baby on the way so need to sort out the driveline by then because after that i know i wont have money for a while to spend on cars.

Its either sort out the uc or i dont have a choice but to sell it and buy something newer (which i dont want to do) and the missus said i should keep the torana which is a plus haha

If i built a 202 i would go for a mild cam, some head work, redline manifold, 500 holley or 34 adm weber carb modded for blow through. It would use my current blue bottom end and a 9 port head. Thing is if i do the 202 it will cost up around $2500 so thought it may be possible to do the conversion for not a heap more.

Then with that motor i would kill gearboxes a lot ive already killed 3 boxes in 4 years

[Stinga]

yep, if you can find a sump from an rb30 patrol i think its a good starting point. i think 1k for an rb30 and box is a bit expensive but if thats your budget for motor and box you might be better off with a cheap rb30 motor for a few hundred and spending the extra money on the rb25 gearbox which is a bit stronger i think? you could probably cheapen it up more by just getting an rb30 and auto. not sure if you can avoid the chassis notching mark mentioned by using a cheap/ebay high mount turbo manifold?

 

if you get in contact with Lee from extreme turbo manifolds, he used to do the conversion mounts. he might not anymore as i think he mostly does xr6 stuff these days, but its worth a shot.

 

also check out turbo76lx's build thread for his rb conversion, maybe pm him for some info?

 

or keep the original motor and spend your money on beer

If you put a Jap motor in your Holden you have to put a Nissan badge on the grill.

If you go though with this there'll be no inheritance from me son.

[Ice]

Honestly just spend a little bit of money on the 202 and built a decent gearbox
3 gearboxes in 4 years easy on the clutch son

[hawk]

Haha the gearboxs were autos i havnt killed the 4 speed yet but i havnt even done 5000 ks with it yet.

A 304 would be expensive as the extractors are 1000 alone then 1500 plus for the motor and box. Then over 500 for the exhaust.
Radiator and all the rest. It will also be heavy in the front and handle a lot worse. Also would need new springs and so on.

The 1000 for rb is a complete car a guy i know has for sale so would have radiator, fuel pump, motor, manual box, ecu and i could have the exhaust connected to my current system with little work for less cost. The conversion gear from crs is about $1300

Now im just getting myself confused haha

I have a mate with a 400rwhp rb30e + turbo, it was a normal n/a motor that he put a good steampipe manifold on with a cheap turbo & aftermarket ecu etc. He's just got another rb30 for it as he wore his one out!

The trick is to get one from an r31 or gq patrol, it wasn't anything to do with the radiators in vl's causing cracked heads, it is because nissan gave holden all the "factory second" heads!

[76lxhatch]

Then over 500 for the exhaust.

This tells me that you are not set up to do all the work yourself, which unfortunately for you means that your budget is quite unrealistic for such an engine conversion. It also sounds like you don't have a long time frame to get it all done?

I agree with the best bang for buck being to spend some money on the 202, they can be plenty reliable and still a bit of fun.
