hi there

im new to scoobys and i have always wanted 1 and when i got my v4 sti i had a nightmare lol, first night the turbo went and by the 3rd week it was on the back of a recovery truck with a knocking engine . work ended and i found myself having to break the car in order to get my money back (gutted).

but im not giving up on them just yet, so im going to rebuild and forge my knocking engine myself to keep cost down with help from a local garage and you guys over the next year. with the plan to buy a 2 door typr r next summer and swap engines . lol

right to the point lol!!!! today i got the engine stripped to the block and ill be splitting it over the weekend and i can tell you that its done two bearings that i can tell up to now, so im wanting to know if someone could help me by giving me a list of parts i need to source for engine and what machining if any is needed and what to do next after the engine is stripped

thanks lee

yes this is great help but 400 bhp im after anymore a bonus really, is the semi closed block ok for this as everyone talks about closed decks. and whats the best oil pump to use or is a modified 1 ok

semi closed deck is fine as is open deck below 500/550 and id use a RCM modified oil pump or get Harvey smith to modify it as he's atop bloke

v4 sti wont have a semi closed deck

lhendo-sti

am i after a new standard crank then or do i need a stronger 1????? i have been reading about not been able to regrind subaru cranks is this true as there is people on both sides on this

lhendo-sti

it has had a v8 bottom end at some time but did not have proof till i got the heads of today

If you can find a decent machine shop they can but it a very mixed thing 'subaru crank grinding' as some say a defo no no but others disagree but id get a nitrated v9 crank as they are the strongest mate.

lhendo-sti

yeah i have read this with people saying about regrinds blocking the oil ways in the crank with metal bits off machining and others saying a gd machine shop would be able to clean this out no problem, guess new is safer lol

does the v9 crank fit without any work ????

prodriverules

imho yes but it all depends how deep your pockets are lol,regrind is half the cost of new.

lhendo-sti

im doing it over time so i want it done right as i dont have the car yet and dont want the same happening again

defo go with new then mate,it doesn't matter how long it takes as long as its right,ive had mine off the road for 3 months now forging the engine mate lol.
Time is something i just can't seem to find,ill be putting the engine back in tomoz yipee

lhendo-sti

sounds like it will be worth it tho, just wish i had a better start but im looking forward to getting this done like.

not at all mate to date including all the suspension and brakes and electrical mods about 10/12k mateand its not been mapped yet lol

lhendo-sti

bloody hell mate this must be a machine when finished. what bhp will u be running???

just been looking on ebay at some parts and i have found some mahle forged pistons with cosmetic gaskets for 500 and v9 crank for 550 is this a gd price???

It shouldn't be to bad mate lol,im hoping to see around the 500 or so mark,ive got one of only 25 early prodrives built so it agood one as well,and that power in a classic should be a useful tool
I'll be posting some pic's when its finished so keep your eye's peeled lol.
Though's prices aren't to bad at all mate,i went over size on my piston,s so i could have it bored out and be shore i had a nice straight bore and fresh honing to boot.

lhendo-sti

ill look out for them pics mate sounds awesome
