worthwile mods when rebuilding an engine
Turbo Mini Forums

Hey guys I was wondering if there were any worth while mods when rebuilding an engine to prolong the life between rebuilding . Im sure I seen someone drill their thrusts on the centre strap , mods like that really any other worthwhile mods is appreciated to

Thanks in advance guys

id say just a proper build and you should be fine then dont push it past its limits like i did with the first engine..

std valve springs plus cam and lots of revs on the 1100 killed the guides and seats that lost compression and burnt oil cracked the crank also treated the box like crap so it went pop and trashed the oil pump and bearings

if u want it to perform build it to if not do a stock rock and treat it like it thats my advice

things to do that should make it nicer would be

cross pin diff (the offset type not at 90)
double row timing chain to prevent timing moveing to much with wear
new front damper as the rubber can go to shit with out looking like it
quality gaskets/seals
ensure all bearing are correct running clearances as well as the box is setup properly inc drop gears
balance the rotating assembly for smooth running and less wear
in the box put one of the leak kits in its a alu bush with an o ring then a new seal this suports the shifter rod letting the seal just do its job rather than both suport and seal
perhaps think about a taller diff to bring rpm down at cruse this will help engine life
probaly a lot more that can be done but things like good oil and letting it get to running temp before driving it help a lot

if its a turbo motor id put megajolt if standard get one of the electronic ignition kits best thin I ever bought for my 998 no more starting issues

Done now needs redoing lol

Undercrown oil cooling jets on a turbo motor, possible oil fed thrust conversion.

Sorry guys should of mentioned it would be on a turbo motor. My planned spec that I want to aim for is :
Benross head
Block bored to 1293
Omega 10cc dished cast pistons
Lighten and peened con rods
Balanced crank
Centre main strap
Avonbar ph2 cam
Duplex vernier timing chain
New core plugs and oil gallery plugs tapped
Lightened flywheel with an rts clutch
Helical drop gears
Sc cr clubman gearset
Cross pin dif
2.9 fd
Gt17
Intercooler
Oil cooler
Megajolt
Med crank damper

Would like to see the 150 mark really

Properly set up 150 should be very easily achieved on that spec.
