Title: Engine Conversion Queries ;)
Post by: Rachie.V1 on 31 May 2011, 18:22
Riiiight,

I decided I'm going to do a vr6 conversion which was discussed on the other post! (nice and lengthly! haha) butttt, I'm wondering now about the 1.8 turbo engine, however I just read that the 1.8 is 180bhp and the vr6 is 174bhp?! Doesn't seem that mcuh of a difference for what seems more work? But I don't know if I've read something wrong..?

Also, what other engines should I look at and what other cars can I get these engines out of other than golfs?

Sorry to be a bother!

Kells is putting an s3 engine in his  :cool: the BAM 1.8ts are 225 bhp but are also pretty expensive! I just have the 150bhp AUM in mine but it feels much quicker than a vr6, and has torque that lasts forever

the 1.8t will also use MUCH less petrol than the vr6, and although I know little about vr6 engines I'd imagine theres more you can do to a 1.8t tuning wise?

there's a bam engine going on ebay and i'm watching it but i doubt i'll get it, seems to be going up pretttty expensive.

yeah that's what my partner said but i can't seem to find a 1.8t for around the price i was gonna pay for the vr6 :(

Get yourself an AUM lump and a KO3s turbo add an FMIC, exhaust and a remap and you'll have 215bhp+ and will still get 35mpg. Compared to the 170bhp and 20mpg from a VR it's win win :cool:

You will need a mk4 donor car  :wink:

Can get about 260bhp from a ko4 turbo too. much easier to get power from a 1.8t, but and a every big but is, fit a turbo to a vr6 and you can reach 500bhp

I think for that kinda power you would need a completely rebuilt vr engine low comp pistons etc then a good turbo kit and stand alone management an a good gearbox with LSD. I would guess around 6-10k depending on quality it's not something you want to cut corners with :shocked:

Pick up a cheap Skoda Octavia RS as a donor car, then sell what you don't need.

180bhp standard and really good on fuel.

Get a 1.8t out of audis, seats and vws. A4s weren't too dear a few months back

A4 is no good as a donor as the engine is the wrong way.

wouldnt bother with a Vr lump personally, too heavy and not that quick for the hassle but thats just my opinion, iv got the S3 lump going in mine as we speak, and with the mods iv got for it, i will have between 260 -280 BHP which will do untill i get a LSD

if you want V6 noise, fit a 4mo engine or a R32

Post by: Rachie.V1 on 01 June 2011, 09:18
right so i'm going for a s3 engine or a skoda?? haha.

i think i need to decide so i can stop doing my bf's head in and changing my mind :P haha
Title: Re: Engine Conversion Queries ;)
Post by: Rachie.V1 on 01 June 2011, 09:24
s3 engine is out of price range for the minute (can only find ones that are like a grand!) so looks like i'm going for a vr6 and doing that up to the bollocks like.

whats your budget exactly? I got my 150bhp AUM for £800 which was expensive but I was impatient lol, but the conversion probably cost me around £2800-£3000, you need a lot more than just an engine  :grin:

Try and get your hands on a rear ended mk4 or a3, take then engine etc out and sell the rest for parts and the conversion will pretty much buy itself, depending on what you start with you'll just need a sport cat/de-cat, downpipe, bigger bore exhaust (eg 16v jetex system) and other small bits and pieces

If you wanna do things on the cheap I'd advise getting an AGU, its 150bhp same as the AUM but only has the K03 turbo as opposed to the K03s in the AUM. Its easier to put into a mk3 though as its cable throttle so theres no messing about with putting electronic pedals into the mk3, and you can swap to the K03s later on for more power :)

Defo get a 1.8t. as said vr is waste of time.

I love the sound of my vr6! big Simota open carbon induction kit, just a backbox on the exhaust. sound amazing.

I will be buying a r32 next and not a Audi S3 even though with a few parts and a remap the S3 will be far quicker.

don't have an overall budget but atm i don't have alot since we just got back from modded nats and the partner went abit crazy with his cougar, lol.

it'll probably be a next month thing now, that's if the cougars clutch holds on (lovely surprises them aren't they!!) I need to get having a proper look for a 1.8t then, but what i might do is get a vr6 rip that out put that in the gti then get a 1.8t for the then empty vr6 shell... hm, i don't know.

any ideas of the best places to look for a 1.8t then? :)

Ebay etc really, however you better to get a complete donor car and then sell what you don't need afterwards.

I've found a 1.8t from a mk4 golf for quite cheap!!! Just thinking if I get that now then I can get the rest of the bits and bobs I need when the Cougar decides to play nice, haha.

Thats a non turbo 1.8 = babba!!
As Wayne said the AUQ from the skoda would be a good base, bout half the price of the AMK/BAM and at a not too shabby 180 ponies, seen the engines go for around £700
Title: Re: Engine Conversion Queries ;)
Post by: benvictors on 01 June 2011, 14:04
Theres an AUQ on the bay at the now, its got all ancillarys and has covered 85k, £850
You will then need a 16v pressure plate, flywheel, gearbox, hydro clutch set up, cable change gear linkage and clutch, if yrs is an early spec 8v you will also need the pedalbox from a later spec car.
AUQ loom and ecu, and, will need to send the loom off for splining into yr existing one to run factory management.
Custom downpipe, cat and exhaust system, FMIC and all its pipework, various brackets, hoses, clamps etc etc etc  :cry: :cry:
Worth it in the end tho :grin:

Ideally you want to buy a donor car with the engine still attached. That way you can see the engine running and give it a good inspection rather than taking a big gamble and possibly ending up with a smoking engine or one damaged upon removal.

Yep, it is a much better idea, as you can confirm what condition the engine is in before fitting.
