project 31 8k 5 port
Turbo Mini Forums

another super budget build !(please refrain from any suggestions that involve spending money! )

so , having found some bits at the scrap yard ,and autojumbles ,i realized i have nearly enough bits to make a high rpm 5 port ,a bit more extreme than my mildly tuned 42 mpg 247 bhp 5 port i have now .and i can put it on the 16v gearbox and play with it in the hybrid car .


so , i have a plus 20 block from a allegro i think












found in the mud at the scrappy ,

and i found a manky looking set of pistons at an autojumble for 20 quid,,that actually came up quite well,,and turned out to be richard longman forged omega offset dish ones:):) ,and +20 too !






cleaned up well...




and the block was ok too..







bit of a hone




some water damage but hey ,7 thou bore clearance is fine eh good for high rev low drag (he tells himself)

thats the progress so far , i have some arp rod bolts thanks to nic and joe .and a some high poundage springs for the head oh and some inlet valves from andy bellers .

i need to get a set of exhausts ,but might make these from some old stainless inlets .
i have a unleaded head i can port out to my trap head design ,but a bit more extreme than the lower rpm engine ...and i have an old td05 16g off a subaru that might just work ....

should be fun ,, ,this will run around 9.5:1 cr ,and my own cam design ,and water injection if needed .time will tell , not expecting very fast progress ,but ill chip away at it when i can ,and wanted a record on here of it all ,,

oh oh , may try the trionic t7 on it ,or i have a blow through dellorto to use to .

regards
robert.:)

Watching with interest.

I'll have you know them inlet valves were once in the fastest metro van in the world!

If something is worth doing, it's worth doing half of.

Another interesting one.

Those pistons were a great find!

In the 13's at last!.. Just

Yes you lucky devil!

Impressive job on cleaning up those pistons, how long did that take and how did you clean them?

I shall be watching this with interest. First NOS-less 300hp 5 port ???

I have a complete set of mains and big end shells, in VP2, standard size.

The mains are the A+ solid bootom half type so will need the cap slotting.

Just did a few thousand miles in the 1275 before the swarf incident.

Yours if you want them.

Robert, I may have some new +20 Omega rings if you need them, I will have to have a dig through my stuff as I cannot think exactly where they are.

Another great project by The Man : Robert !

What is your trap head design ? (I'd happily copy it if it suits my needs / skills and you're OK with it)

Rusty by nature

My last lump was way more than 7 thou clearance and was ok.

soo you gonna use that headgasket again?

also make sure you run a stone round the hole above the centre main.

If not, I've got a good, used gasket.
