Title: Big Turbo Matters
Post by: Purely VAG on 19 December 2010, 19:15
Been weighing up a Forged engine build for a while, Kept an AGU lump back off a breaker for exactly that, I've just bought Comptons lump off the forum being as it was Very cheap, silly not to.

Question is, 350bhp in FWD mk4 with no LSD, Its been running 5 speed box, at very least i'd run a PD 130/150 diesel 6 speed with SMF. Though am i back where i was before and should be hunting another 4motion shell to house it ??

What do you think lads? MK4 as it sits now with K04 lump in.....

4mo 1.8T would be the best.. that much power through front wheels is not going to be fun.. car looks nice tho mate..

if its spinning then its wasting power.. its all dwn to can you afford a 4mo shell and all the probs you will run into..

Post by: Wazzzer on 19 December 2010, 19:21
personally I'd 4mo it seeing as you have the opportunity to find a nice shell...

Without an LSD it would be a bit pointless, as you have already decided!
Given the option stick with 5 speed over 6 speed as you will be going through the gears constantly so less fun.
You not tempted to go stand alone management with that engine to make the most of the 1.9T?

Why you against the LSD? I love mine in the mk2, best mod.
Title: Re: Big Turbo Matters
Post by: tech1889 on 19 December 2010, 21:39
i wouldnt change that turbo its a good turbo and can handle more than 270 bhp.. and faster spooling than t3..
Title: Re: Big Turbo Matters
Post by: Purely VAG on 19 December 2010, 23:48
Well its mapped for 346bhp at moment. And im looking for a shell before i put engine in anything. Just going to try sell this car.

thats a good idea mate your car is advertised at a very competitive price.. hopefully it wont take you long to find a decent 4mo shell..

Personally id go for LSD. With the 4wd you'll be losing power more through the transmission and then you could have problems with the haldex. Alot of guys with R32 Turbo's running 400bhp have to resort to different Haldex controllers and maybe more
Title: Re: Big Turbo Matters
Post by: tech1889 on 20 December 2010, 16:35
30% through 4wd transmission

Post by: AaronGS on 20 December 2010, 18:29
there was a feeler for sale thread for a gearbox with LSD a few weeks back, I think on Seatcupra.net...
Title: Re: Big Turbo Matters
Post by: Purely VAG on 20 December 2010, 22:19
Fair point, Can't beat 4WD though but keeping this shell would save me alot of hassle.

Thing is i need to run 6 speed with 350bhp, Even now its feel stressful sitting at high revs all time.

Im contemplating just fitted SMF flywheel, paddle clutch and using a PD130/150 gearbox.

Why do you think you need 6 speed with 350bhp? I run that power and the 5 speed is great. Dean at Awesome used to run the same power but through an anni 6speed and said it was a nightmare and believes mine is much easier to drive. Getting through the gears on a 6speed is not gonna be fun, sometimes I wish mine were longer. just put an LSD in yours and away you go till you find a 4mo shell!

Jord - after speaking with Nick a few months back sounds like the diesel box is a good idea. think he said he had seen one that was on a 1.8t and was easily getting 110-120mph in 3rd gear
Title: Re: Big Turbo Matters
Post by: Purely VAG on 21 December 2010, 12:15
Aaron, The ratios too low on a 5 speed, Setting off with 6 speed diesel box is like setting off in 2nd on 5 speed. Means i wont be spinning up and final drive is much much longer. Theres a vortex thread listing ratios
Title: Re: Big Turbo Matters
Post by: tech1889 on 21 December 2010, 12:23
is it gona be easy mating the 6spd up to a 5spd engine ?? i no most people say its too much hastle to change from 5spd to 6spd is it really that bad ??
Title: Re: Big Turbo Matters
Post by: tg1 on 21 December 2010, 12:35
i doubt its thaat hard, but if i was to do it, all it would involve was a phone call to my mechanic and some money  :laugh:

Ah, didn't catch the diesel bit! Fair enough, will be interesting to see how easy it is to do and how it works. Longer final drive will be good.
I do not spin up unless its very wet but even then it is controllable if you don't just floor it!
Title: Re: Big Turbo Matters
Post by: Purely VAG on 21 December 2010, 21:14
Going to try the diesel box on it, if that doesnt suit ill hunt a 4mo shell.

6 speed box mates straight up, Change selector, shafts, starter. Adapt hydro line, sorted.

i no its not about your thread how much including box would you charge for the swap ??

Post by: Phil_M on 21 December 2010, 22:18
Personally if your going to stick with 350hp i would stay with FWD, i have heard a few people say that 4WD big turbo cars running that power don't feel as quick and are not as much fun. A well set up FWD car is easily capable of putting the power down from 2nd in the dry  :wink:

If your thinking of 450+hp in the future then go for 4WD.  :drool:

As for gearbox i am still running 5 speed with ATB diff although gear set has been Cryogenically Treated(frozen) and its never let me down running 370hp with racelogic launch control..
