After some advice

[Worbs 0]

Hi all im going to be supercharging my vr after xmas and i just wanted a bit of advice on things, my current vr lump is in a bit of a sorry state its done 176thou miles and im pretty sure the head gasket has now gone, for this reason would i be better of buying another lump and rebuilding, i want to keep the car on the road as much as possible really so i suppose the obvious answer would be to buy another engine and rebuild in the garage,

When rebuilding what are the most important things i should do, i want to run as close to 300bhp as poss with a supercharger, will standard rod/pistons be up to this what would people suggest for rod bolts? standard ok or arp`s are needed for this kind of power, i haven`t a clue when it comes to vr lumps. just the must do things with these engines really.

Thanks in advance

All I run on mine to get around the 300bhp mark is lower comp spacer and metal layered headgasket and ARP head bolts.

Should be fine, Jim potter is running around 400bhpp and no more than that also. It is possible but always better to over engineer in the first place

Thanks for reply fella, Ok thats brilliant if the standard rods and pistons are up to the job that save well over a grand lol, what supporting mods have you got mate? What sort of charger/ pully size would i be looking at and what sort of boost levels would i need would i need an i/c or could i just run a water/meth injection, also mate what about fueling any upgardes needed in that department.

Soz for all the questions just wanna get it right lol.

Well im running a rotrex with a 6 psi pulley at mo with no cooling. I run a rising rate fpr for fueling and also have a walbro 255lph in tank fuel pump.

IC is really for when going big power, but water cooling would be a bonus to help keep boost.

It all depends how deep your pockets are. TonyVRSC on here did run a vortech charger at 8psi and got same figures as me but on a 2.9 engine

Lol pockets are deep and arms are short mate lol, nah im due a nice tax rebate very soon so that is going to be spent on the car to start me off then bits and bobs monthly will be the way forward i think, i not long ago sold a nice fpr that i had on a big power subaru i was building dam lol, ok fella so standard injectors should see me around 280 300 yer?

If i went for say a vf or z engerneering @10psi with mods you said head gasket spacer rr fpr an walbro the water/meth etc i should be ok to run a safe 280 lets say?.

thanks again for the advice fella.

HEELP lol.

ha ha everyone is tempted by Jim's thread :) well mate if you are after 300bhp on a charger you don't have to do too much else to the engine - as Craig says a Begi rising rate fuel regulator and maybe a spacer gasket and some uprated injectors and your good to go as said on Dub-Gen am more than happy to have a catch up and can discuss some ideas or next time I am going to Jim's you can tag along and get more tempted by his car ;)

allo fella, im so so tempted to follow jim's lead lol, im thinking iv got this tax rebate due soon as done me self tax return a few month's back i should get just over a grand that would pay for most of the bit's for me go down the turbo route an ill prob be lookin at around 2k to supercharge, defo have to meet up fella would love to see ya motor in the flesh an would love to come an see jim's vr, got to sort mine out asap as developed some scarry brake judder under braking an the abs light is staying on prob the disc's warped i reckon, good excuse for a decent set of discs an pad's i think lol.
