    306 XR to GTi6 Conversion Info Needed

    Hi guys i purchased a 99 model 306GTi6 today at the auctions. The car is a writeoff (the car was rolled and most body panels are damaged) the car is fixable but would cost too much. What im gonna do is drop all the GTi6 bits into my 1997 306 XR to bring it up to GTi spec

    I have a few questions though-

    Has anyone done this before? And does anyone think it will be very difficult.

    Advertisement


    Is there a big difference between the XR and the Gti suspension componenrs or rear torsion bar?

    Will the stock XR fuel pump be adequte for the GTi6 motor?

    Are the brakes on the gti6 good?

    Also does anyone know how much a GTi6 and a XR weight?

    What are the main differences between a XR and a GTi6 that i should know of and upgrade?

    What i wanna do is swap the engine and the gbox driveshafts. I want to swap all the suspension components and the brakes. Also im going to put as much GTi6 interior into the XR as possible but ive noticed that the 1997 and 99 models differ slightly....hopefully i can make a nice hybrid of the 2.

    Anyways ive got more questions but ive forgotten them if anyone has any tips or advice id love to hear it and can sumone please eleborate on the N3 and N5 chassis? Cause ive heard ppl talk about that before

    Anyways thanks guys

    From what I know, all suspension components are different in the GTI, however this does not necessarily mean thay are not interchangable, just different ratings possibly.

    As for the engine, so long as you move the whole kit and kaboodal over, I wouldnt think there would be a problem, however chnage your tacho faceplate as you will fly past 6200 with ease.

    Everything else should be interchangable though as AFAIK PSA designed their cars to be very modular to cut costs. For instance the wiring loom in my car has HEAPS of spare connectors I am told fit all other 306's and late model 405's.

    Just make sure the stearing rack and brake systems are the same, you dont want to skimp on them. Sounds like you are in for an entertaining few months.

    Yeah im gonna change the dash display as well its a must cause the gti revs to 7000rpm wheras mine only 6000rpm.

    Like u said alot of compoents will be interchangable and thats wat i presumed like the wiring loom ect hopefully it makes things easier.

    Yeah im gonna upgrade the brakes because ive only got crappy drums at the rear.

    As for the suspension compoents yeah i want to upgrade to gti6 specs.

    Anyways i think its a good time for a conversion cause my CV joints were making funny noises. lol

    BTW how much do u think a 1.8 8v motor with 87,000kms would be worth?

    Anyways yeah its gonna be a long few months i think ill do bit by bit.....mmmm interior sounds easy ill do that first.lol

    From what I know (take a pinch of salt after reading and VERIFY with others):

    1. GTI brakes are larger diameter and are not interchangable with other 306's
    2. driveshafts are larger diameter to handle extra power
    3. struts are larger diameter with larger shocks
    4. swaybar larger diameter (I think)
    5. gearbox protrudes into the left wheelarch and may need bodywork cutting

    When you change the brakes verify the bias valve is still ok with your lighter car.

    good luck!

    Yours is an N3. The N5 was introduced in 1997 as far as I know. The main external difference is the nose. Deka has an N5, eg the newer fan grille, headlights, and the peugeot symbol on the hatch. With the update the manual gearbox'd cars recieved a 16v in both 1.8 and 2.0, although autos kept the 8v versions. S16 was replaced with the GTi. I'm sure there are plenty more things the 306 owners on here can tell you about I'm learning more as I'd like to get a 306 as soon as I can afford one wink .

    Oh yes, and I wouldn't expect your car to keep its weight when you stick in all the GTi stuff, no doubt its gearbox, engine and suspension bits etc will be heavier than your XR parts.

    True, but if you changed all the components including the calipers and wheel hubs, there should be no problem, so long as the control arms holding the suspension and wheel hubs, and strut top mounts were the same as the XT.

    I would think there would be alot more problems though if indeed the XT was an N3 chassie as opposed to the N5

    But he does have an N3. If you look at the pics linked in his signature, it is clear he has an N3. It must have been a very late one though, if it is 1997.

    It's definately an N3 306XR... other ways to tell include the rear drum brakes, the black trim along the boot lid bottom, the headlights/indicators are separate (N5 they're combined into one)

    That could be an issue actually.. changing brakes from drums at the rear to the GTi6 discs with ABS. No idea how that bit is done. The GTi6 has no brake bias valve - it is all controlled by the ABS. This means that you MUST install the full GTi6 braking system as it is or else you'll have no way to control the disc brake bias. I'm sure you'll appreciate the extra stopping power with nearly double the engine power wink

    Given it is a 1999 model GTi6 it will likely (if it is after July/August 1999) have the 'crystal' headlights like my 1999 XSi. If there's any other differences you want to know about just ask.

    Well, I have to say I'm very interested in how this goes. I'd be happy with an XSi engine transplant in my car.

    The rear suspension bits should be a breeze. Just unbolt the whole rear beam with hubs and screw it on your car. You'll also need the handbrake cable, and probably the master cylinder along with the ABS.

    Scrap the XR engine+gearbox for the gti, 6 speed..hmm. You'll need minimum 15" wheels to fit the gti brakes for the front, shouldn't be a problem with your 17s though.

    The interior bits should all fit easily, I doubt they made many changes to the seats. You'll need to redo all the wiring for the dash if you fit the newer style one in.

    I can't wait to see this car completed now!

    Besides all of the cosmetic differences listed the body is significantly stronger due to a higher number of spot welds. The exact number escapes me. As Tekkie said, the GTi6 gear is big (we have a 13.7 metre turning circle turning right...11 metres turning left), so I'm not sure if you'll require some body work there.

    ohh ok so N3 and N5 is like the Series 1 and 2 pugs gotcha now

    Mmmm yeah ive heard the GTi turning circle is really bad but oh wellz im used to a crappy turning circle anyways.

    As for the GTi6 yes it is Blue and was at Fowles Auctions.

    Im really looking forward to the conversion now...if my XR does weight 1000kg then it should be quicker than a real GTi [finger crossed]

    My friend had a EG Civic and dropped the Integra VTir Motor into his....his Civic weighed about 1000kg with the 129kw VTiR motor and he used to beat Type R's....mmmm i hope my pug turns out as quick as his

    Anyways once again thanks for the info guys

    wow! absolutely amazing stuff! i cant offer you any technical adice, just moral support .
    although sounds kinda ambitious, im looking forward to its completion... itd be such a weapon... im gettn wet just think of it mallet .

    tell me, had you always planned for this conversion, or did it just kinda fall "into your lap"?

    haha thanks for the support
    although sounds kinda ambitious
    mmmm im starting to wonder what ive got myself into...it shouldn't be too hard should it? They are the same car after all and engine mounts ect are the same. Like i said i know alot of ppl with Jap cars that have done engine swaps on FWD 4Cylinders hopefully [fingers crossed] i dont run into any big hickups.lol

    haha as for planning this....mmmm ive always dreamed of it. I wanted to mod my pug to go fast but the 8V motor i have in it is a POS and isn't worth wasting money on....id always wanted to do a proper Turbo conversion on a 306 but i wanted to start with a good base motor...ie GTi6 motor.

    But yeah it bassically fel in my lap my dad told me about the GTi6 at the auction orginally i had planned that if it wasn't too badly damaged id fix the GTi and sell my XR...after seeing it at the Auction that was soon put to rest and im sort of happy cause the lighter XR with GTi compoents will be quicker anyway

    As for the Gti motor yeah if everything goes south itll prob be up for grabs...along with the rest of the GTi6. I just read an older post stating sumone was selling a GTi6 Motor and Trannie for $7000....wow they fetch more than a Integra Type R motor.

    Looks like your from Melbourne too...hopefully in a couple of months you might see a Green Pug flying round town showing sum Riceboys what the french can do lol

    I bet you'll find that when you swap all the bits over your 306 will weigh near as much as an original 306GTi6. The only difference in the weight of the bodyshells would be the extra bracing and welds, etc which make the N5 stiffer, but this bodyshell stuff accounts for a surprisingly small percentage of a cars weight. Mechanical and interior parts (glass, insulation, aircon, sunroof) are the heavy things.

    Very good point but seeing as though my 306 is the base XR model it should weight less than the N5 GTi6 shouldn't it.

    Ive been going over in my head the weight the conversion will put on. The engine/trannie and brakes will put on the most weight.

    The suspension components will differ minimally in weight compared to the XR components.

    The seats will add a few kgs here and there. I will probably weight everything before i put them in just to get sum sort of idea.

    Mmm only thing is my XR came with a Sunroof and Power Windows plus ive got 17" rims which are pretty heavy so yeah it will prob come in close to the GTi weight

    Oh wells itll still be faster that the slow POS it is now.lol
