VTEC killer
Turbo Mini Forums

this my mini project after long day of reflection.
_ 12g940 cylender from my metro turbo
_ metro turbo ignition system
_ turbo T3 or T028 with the manifold
_ big bore downpipe with a big bore exhaust tube and a bike silencer from a R1
_ inlet and carb of the metro
_ the brake sytem of the metro and in rear brake i will try to put the mini standard disk
_ metro turbo cam
_ water and oil pump
_ 13 rang oil cooler from a mini cooperS
_front radiotor mont with a additionnal water pump to cooling the head cylender

but for piston i think of over bore my 998 block to put my metro turbo piston???
guys what do you think of it does this seems pretty good ?

put some thought in to what intercooler you are going to run. This can make or brake performance on a good engine.

I also reckon if you are after big power, 998 might not be the way to go. You can build a sorted 1293 bottom end for sensible money and make power much easier.

A water and oil pump is a good idea, you cant put metro turbo pistons in a 998, as ric says you might as well start with a 1275 block.

junk the metro dizzy and go for MegaJolt or similar.

Don't use the Metro Turbo cam .... just the same as a normal metro cam. MG Metro cam is a cheap up grade but a decent aftermarket cam will be required for big numbers.

Every day is a school day ...........

How fast and how expensive ...... the same question...

my problem is the 1275 metro turbo block have a failure!! but i have 998 mini engine completly rebuild in my garage for free. and the intercooler i will use is a VW sharan front one from the 1.8 turbo engine

But has that rebuilt 998 been rebuilt with forced induction in mind?

Exactly what is wrong with the metro turbo engine you have?

I suspect that "tieeger" is not from the UK?

Why not fill in your profile?

I also suggest you look at the big yellow book, becuase if you are short on information like fitting big-bore pistons into small-bore blocks, then you have a fair bit of background reading to do first...

Good advice dave. Basically, you're in the right place, all the info you need is here. But do a ton of reading in the FAQ and Beginners Tech sections before planning or buying anything.

that's right i'm french. and i have two david vizard book: _how to modify your mini and yellow one than you talk about. the 998 engine have a center main strap and a 12g295 cylender head with 29mm exhaust valve and 33mmm inlet valve

I must reckon 998 doesn't seem the best way to go if your goal is ultimate power.

In my opinion, a turbo 998 is more likely to be "as good as" a Stage 3 1275 then would it worth the hassle and expense of going this way ?

Rusty by nature

A good 998 turbo is much better than a stage 3 1275 IMO, but a 1293 tubo is always goig to make more power.

Use the standard 998 bottom end and pistons on a low boost engine, but if you want a VTec killer then do a propper job.
