building a 2L 8v for turbo?

[GoLfMan]

how many parts are out there for the 1.8 and 2L 8v engines that were in the mk3 Golf for building them for forced induction?!

-low com pistons
-lower compression
-custom manifold
-custom exhaust manifold
-ecu?

not being built for 200hp, something around the 180hp mark could easily be achievable in a reliable drivable set up i think.

any ideas here

josh.. what are you thinking???

maybe a 1.8 with a 2.0 head? would this lower the comp? Prolly have to custom the manifolds, and don't know anything about the ecu; maybe run K-Jet or something mechanical?

Mate its all custom made by local machine shops... I spose u could get stuff from overseas but go local and get the rite stuff made... Cost just as much...

BTW my ol man keep blowing heads of ol skool 8v's so take it easy

well... the stock internals are rated fairly well. Pistons won't be necessary if you get a low compression ratio gasket, then you can run 200 hp at the wheels for no worries

Heres a site that sells a kit, its all pretty bloody interesting stuff if you ask me.

Found a 2.8l 24v VR6 450hp kit the other day for 5000 grand... that wasn't bad lol!

Plenty of folk have done DIY turbo stuff on vwvortex.com have a look in the forced induction thread.

A couple of stacked G60 head gaskets is a pretty std way to decrease compression.

It's pretty cheap and easy to do it simply. 220-250hp with a T3 super60 without silly boost. More parts around than you can poke a stick at aswell

[Golf Houso]

yeah exactly best place to start and to make a list of all the items you need. Low comp gaskets are cheap though 150 posted, thats not bad really....

Tuning would be the biggest pain though... But all car chips are flashable, just a matter of finding the right person with the right level of expertise.

Seemingly people on these forums always use chips or flash their ecu's... coming from imports and such... is there a disadvantage with these cars to use systems such as microtech, wolf, ems, haltec, etc?

You should be able to run low boost (4psi low) through a stock motor even. not massive gains, most likely just a better power band.

If i were to consider this, i'd just get the 1.8 turbo motor and bore it out if you want bigger displacement, or possibly use it's head. I am not familiar with the specs of these engines, but the 8V sohc head more than likely would not flow as much as the 1.8 DOHC head, and when it comes to performance, rule of thumb is that flow = power. Then the issue with the compression is easily resolved with either the use of multiple or a thick hed gasket, or else custom pistons - which you may need to get anyways due to how rare parts for these cars seem to be (to me anyways).

Custom manifolds are big $$$; you may be best off seeing how well a ported stock manifold may work/their restrictions, or how much stock items flow before they restrict power.

k-jet is the worst idea for turbo charging do not do it

I spoke to a guy from malta who had a 1.8 8v mk2 turbo 250hp.

He said it was easy, most expensive thing was the custom piping and exhaust.

He had a stand alone management, DTA or something like that, a desel gasket to lower compression and was running a K04 turbo. Cant remember how much PSI. He said all together with full custom stainless steal exhaust it was 6000 euros.

If you like i can dig up his email address. His car was on VWFixx, still there in the arcives i think.

Whats the budget? Seriously you come up with a figure and we'll spend it (theoretically). Just go 20v rather than pussy around on r&d

[peedman]

That i agree with. When ur spending around 5k for a 8v turbo and a 20v turbo halfcut is around the 3-4k mark it is the more wiser option. Also the gearbox wont like the extra amount of torque since 020's arent really seen as strong boxes.

U THINK 5K will be enough for a 20v turbo conversion in a mk1!!!

try double that.... then add on all the nessecities you need to stop then turn and so on...

y dont u think i didnt go 20v-t

You still need to be able to stop and steer with an 8v turbo.

One thing i have seen guys in the states do is an aba turbo setup, which is a cross flow 8v head. Not sure of the availability over here though.

[WABIT]

but what about extra weight distribution.. its not the 8v it came with originally....

nop crossflow 8v heads are not avalable here
