now i'm waiting for rear coilover and i need to finalize 3d for the front arms and coilover setup

[MX67]

It looks very interesting!

Front diff is from WRX also?
You've flipped the diff in the gearbox without problems?
What is the weight of the engine/transmission/front diff?

Keep it going! Cool ride :cool:

[F4P]

yes front diff from wrx it was flipped upside down for the gearbox i have to bought the reversion kit

[Steve C]

Hi

Cant wait to see more of this, well done.

[NO_H2O]

An AWD 1303 with WRX drivetrain. Now that should be fun. I will be watching this build. Keep the updates rolling in.

[70Turbobug]

Very interesting project! Where did you buy the gearbox conversion kit for use as a rear engine? How much did it cost?

you can find parts here http://www.subarugears.com/

[volkdent]

Really really cool, great idea, I didn't know the parts existed for the reverse gear set, keep it up!

[chug_A_bug]

WOW you are making my Dream come true.... I have been Dreaming for years to build one just no Space and $$ to Do something like this, Keep up the good work man

Chris.

[judgie]

been wiating for someone to try this since the flip kit came on the market. will be watching this with intrest.

[onixbonilla]

I bet a lot of us had dreamed of this before! Been owner of a 2004 STI and 2008 Legacy I can attest the 4WD virtues! Will follow from begining to finish! Also noted that you have a rising custom VW parts bussiness, maybe from your learning you can bring to the market some parts to made this conversion easier!!!:)

[F4P]

news ..
making asm for simultaion of front drive..


the problem is the insert struts was too long.. i need shorter one..

if any body have an idea in wich car i can find short insert struts ....

[superb]

I'm not 100% but I thought that the subbies favored the rear wheels, which now is the front. I think its going to be a front bias system

A centre diff controller should fix that. But i'm not sure how much power that will allow you to send to the front (now rear) diff, a 50/50 split may be all it would give?
AWDVW Awesome!
I plan on using one of the reverse cut ring and pinions in a sti 5 speed box in my 69. Sti powered offcourse:cool:

[F4P]

hello if i'm right the subby was 48-52 or 50-50 front rear .. so i'ts ok for me

[SportyBug]

F4P, are you making camber plates that work with the 1303?

[F4P]

yes they fit on 1302 or 1303

[Humble]

I bought a set of the F4P camber plates and I'll vouch for the quality, good stuff!

As for a strut for the front, A1 golf/rabbit 76-84 has a very short strut, one of the shortest, so you might try one of those.

[F4P]

thank's humble i reajust my 3d symulation with bilstein p30-0137 and it works great ;)

so let's go :)

Last summer I ran the bilstein P30-0032-M0 (rabbit sport strut) with 150lb/in springs in the front and to me, the inserts were WAY too stiff. The were rock hard and I actually lost braking grip because the suspension wouldn't move fast enough. I'm looking to get them revalved for next year.

I put the inserts in with 75 lb/in springs (which were way to soft) also just to see and the struts still made it feel rock hard.

What sort of simulation are you using? I have yet to try calculating compression/rebound settings.

Mike

[F4P]

the simulation is not for calculating spring or valving it's " only" to know if the struts can work fine in length.
i can't calculate spring or valving yet i don't know the final weight of the car in the front

Ok thanks. Just thought I'd add my two cents, amazing project by the way!

[spannermanager]

I would advice you to raise the trans before going further to the point of no return, a lot..... your shaft angles will make short work of the cv's and sap engine power.

[Bugscandrift]

AWESOME!!!!!!


Hurry up and post some updates.. This is making my 1915 turbo look like an old dog!

[Bad bug]

Bugscandrift, how is your 1915 turbo, does it make good power and does all that power come in at a low RPM. I am thinking of building a 1915cc t1 engine first before i build my t4 then the waterboxer.

[Bugscandrift]

Ill let you know once I get it running.. Its close... Real close.. I actually have been working on it all day, but Im taking a break for lunch right now..

[knopis]

any progress?
