Just out of interest
I have a standard ish 998
I just have purchased a 295 head and getting a new carb soon
Just wondered how much would the costs be approx to get it up to a basic 80bhp spec like yours?
And whether it would be okay to run on my engine as it has done 60,000 miles?
Thanks
Greg

My engine had done 70,000 when I turbo'd it, but I knew it's history from 20k an knew it was in very good condition.

It cost me about £1k with the mirage manifold, It'd be hard to do it for less.

Manifold £350
Turbo £150 minimum
Carb plenum etc £100 minimum
Megasquirt/jolt £150-200
Head £200 (including recon)

You can se how it quite quickly adds up, And I havent included a fuel pump and regulator or an intercooler an piping for it, plus al lthe little bits like fuel pipe, filters andunions, oh and an exhaust!

I had lots of 'spare' bits in my garage when I did mine so the cost was kept low.

Okay thanks
I think want to go for a 998 turbo for something different but may save up a bit more and do a bigger build of it
Say add another few hundred and get new piston and rebore and a cam so can turn the boost up a bit more lool
100bhp would be nice

Seriously, please. I don't mean to be rude, but just read the thread through.

ALL the answers you need have already been given. the last 2 pages of this thread have just been a waste of space with people asking Will pointless questions that he's already answered in this very thread.

[project mini chris]

sorry >< that was me not thinking, i will get it removed.

my question is what if you use a gt17 turbo on a 1301 (+30 pistons)
is it worth it as i can only see people using this turbo on 998's?

[Wil_h]

I can't be arsed re-reading the whole thread, but a GT17 is only of use on a 998 where you want maximum power but a compromised boost threshold. The GT17 is ideal for 1300 and above.

No.

There are lits of different types. You ideally nee one with a compressor A/R of 0.48 and a turbine A/R of 0.35. You also need one with a 4-hole flange to make fitment simpler.

that one?

im guessing the montego one is crap but i though it was worth a punt.

[D1k1m4y]

?

Iirc the Montego diesel has the same AR's as the R5, so in which case it will be fine to use.
