repower car 128


well as my engine droped a big end bearing on number four yesterday.

i going to fit the sr20ve, which i all ready have.

have any people opened these up?

i noticed there is no bracing like the de version.

 

i going to fit my custom steel sump whichg holds about 9ltr as it is 4mm steel. but i need t extend my pick up and want to fit some kind of windage tray or baffling in the sump.. has anyone else done this? on these motors.

 

i dont want to suffer from a failed bearing for awhile :)

I am nearing the end of a rebuild to a SR20DE so I don't know if it is any help, but our target is 250HP plus with usable torque.
There is a dedicated SR20 forum which is hard to navigate but the info is mostly useful and whatever you are doing someone has done it before.
I have just ordered a sump with inbuilt baffles, but I have to change the frame to fit it in.

yes i want to keep the custom steel sump i all ready have, which is made from 3m steel, as i dont like the alloy ones for off road. i guess i will have to make some kind of tray my self to fit in it. iam also looking at a accusump system. just incase there is a slight lose in oil pressure.?

anyone used them before?

also does anyone know the spigot bearing shaft size on a 2ltr kombie box?

i think this might be the cause of constant input shaft seals leaking. as there seems to be a fair amount of wear. possibly input shaft worn.

the shaft size is 14.70mm dont ask me how they(VW)come up with that,i just measured the two 2lt kombi boxs i have here,4mm-3mm sump,factory lucky to be a 1mm and amply strong,be nice to your suspension!!!!!

yes motor was out yesterday. failed number 4 big end.

14.7mm pretty sure i cant get a bearing to suit that to fit the flywheel. it currently has a 15mm one. a 6002. unless my adaptor is not made correct and not centered. as the seal did not even last one lap arund colo it was a new seal by race trans australia..

only reason i want to use the sump is it is all ready made, and fill bolt straight on. and holds approx 3ltr more then standard. i would just hate for a rock or stick to puncture my sump or dent it, in way that it blocks the pickup..

so my concern is why did the seal not even last 1 lap? i all ready had the new engine. before i had the car.

mmm what to do :)

ian no worries on gen set info. hope it wasnt to late as it was gone when i looked todya.

Check the input shaft length, the 2 litre input shafts are about 15mm longer than 1600 and 1800, it may not even be reaching the spigot bearing depending on what bellhousing you are using and what the adapter plate was built for ?

i couldnt find a spigot bush/ bearing to fit mine so i got a GM bush and machined it down to fit the crank ,they are 15mm id,i made it a little more of a tighter fit in the crank,it turned out perfect ,my spare engine was a little tight so i used an old input shaft and worked it till it ran freely,you need to look a bit deeper with your oil leak,they are usually quite good and dont give any trouble(make sure your gearbox breather is not blocked)

yes, gear box breather is /was not blocked. the adaptor plate was built for sr20. to kombie, when glen had it it was find but he used original adaptor plate and fitted to his car, so he got a new one made. and it looks like the trouble started then.

so possible alignment issue with the plate. i will check alignment with plate bolted to engine. and run a wire out to where the vw bolts up to, you can see the mark it left and check alignment. as the flywheel had a spigot of 15mm id. but like you were saying tine,
the vw arnt 15mm but 14.7 i guess .3 aint going to cause that much of a issue.

ok slight update, put the adaptor on and made a tool, to check the alignment while turning the crank. and adaptor was all good not out of square and centered spot on,

how ever while putting in on the engine it would not sit flat, and found that a oil gallery plug was actually sitting out of the block and was hitting the adaptor causing it to not sit flat. by about 2mm over all.

also poped the seal out of tranny and noticed that there is some kind of plate inside the tranny that looks worn out. i might need to pop the bell housing off and check it.

have now modified the oil pick turned out perfect, just in process of making some baffles for sump as it has none at all

ok bit of a update, found out old seal did not have a spring on it. so that was main reason for leak, as well as it was a old seal not a new one, but thanks to ron at race trans sent me a seal for nothing top bloke.

also found the a new rocker cover as mine had a crack in it, and found a cam angle sensor to replace the distrubuter. will also give me a lot more clearance against fuel tank.

clutch is nearly rebuild should be here mid next week. engine bolted in no worries apart from the engine mounts had to change them.
also mounted the howie powersteering pump.

and was able to unbolt the throttle body and bolt original on on new engine, so gets ride of all the other wires that were needed for the auto.

all the sump baffling is done and sump is on.

new radiator turned up, ended up using a rover v8 alloy radiator good price at 190 bucks it is 56mm thick and only 600 square. so a 15" thermo will fit nicely.

will be running the coil on plug, and ditching the distrubutor.
so hopefully in two weeks i should hope have the new engine fired up. and get tuned. but not with the quad throttle bodys. that will come later.

wondering if anyone can help, i got engine in and installed and went to fire it up today but no go.

the engine that was in previous was a sr20 s13 engine, and now a sr20ve it still uses old throttle body, and a cam angle sensor. only real difference is the differnt coils. they are pencil type and are to suit a s15 sr20, i did notice that the wiring locations ie pin outs look different. old coils from s13 has plus,neg and e s15 coils have plus grd and ib?

any thoughts. other then this it right to go to tuners to get tuned. fingers crossed i get it sorted before crookwell.

Depending on computer and Ignition system you are running, The coils for some of the s15 engines have there own igniters built in, so if you are trying to fire them like the s13 you may have a problem. I had to by pass the EMS ignitor in my loom to get it to fire.

Cheers  Paul.

going to tunners in the morning. fingers crossed it all works.

paul,

my tuner is having a problem he can get the coils to fire but he has to swap the power and earth over on the coil, which will over heat it.

other then that he cant get it to fire. so dont know

they are s15 coils and a ems dual sport, he said it still needs the igniter box like the old coils? but is it not all ready built into the coils?


any help would be good. as it looks like crookwell is out for this round (

We had the issue on by brothers car running the s15 turbo engine and EMS 8860 Computer. We could not get it to fire and were told to bypass the ignitor as the s15 coils had built in ignitors. All i did was un plug the ignitor and jump the wires accross the plug and it fired. Peter Skaza at Cardiff does our tuning and is a wiz with the EMS, He might be worth a call 49546961. my number is 0402088473.

Cheers Paul

hopefuly electrical issues sorted. but then the starter failed. which i was able to fix. so fingers crossed i get the car back today. :) unless something else goes wrong lol

is there another type of starter that will fit the 091 transsmissions? the vw seems a little gutless.
