Bollocks, should have looked into block heights before i started building my engine, cant beleive i missed that trick

(mine is the same as the one on the right)

 

building a very high compression engine?

 

 

No mate, fairly low compression, 8.2:1

Just gutted i could have started with a taller block and didnt realise it.

Means i could have increased the crank throw half a dozen mm and had some extra capacity whilst also lengthening the rods to end up with a better than standard rod angle.

 

live and learn mate

 

Ive already got:
steel crank
steel rods
pistons


to fit the shorter block

 

So are they just Different capacity units?

 

dohhhhhhhhhhhhhhhhhh

 

Appart from the height whats the difference in the blocks? one XE one ecotech?

 

block on the left is the 2.2 frontera block, both are XE

Someone mentioned to me ages ago about using one and i dismissed it out of hand saying "vauxhall are cheapskates they will just have shortened the rods to allow the extra throw on the crank, like in a 205"
fuck me, talk about me making an assumption i know about something when i didnt

 

Assumption is the mother of all fuck-ups... Could have asked me mate... My friend witht the 280 bhp corsa rally car is using a bored-out frontera block.

 

 

doh

youve done far too much to the block now mate, dont let it piss you off too much.

as they say, you learn from mistakes

 

this always happens chip, i have done the same with my car i now have 2 or 3 of most things

 

Im on my:
3rd turbo
2nd manifold
2nd ECU

And ive not even finished building it yet


Have just been speaking to Rob, and im going to just carry on regardless with my current engine, i just cant justify another start from scratch now really.

Hopefully 500bhp+ should be fairly nippy in the mini in the meantime and i will build one based on this block later on to replace it when it wears out.

lol

 

gutted


but does it really matter?!

Alex, will tell you that when i find out wether or not i can avoid surge on my GT35R.63 turbo mate.

With an extra couple of hundred CC it would have put me in a much better place on the compressor map for the head and cams etc

 

Chip, will you be able to map out any surge?

 

Depends on what you mean by "map out" i can limit boost versus RPM to map it out that way, there is also the possibility of altering the cams to allow the engine to flow more air for the same pressure.

Sadly though as ive NEVER seen this turbo on this engine before, its all guesswork based on what happens on YBs with that turbo

Im not too bothered if i have to limit boost until high RPM, i wont mind if i dont get full boost till 6000rpm+ really, but its just annoying that for no real extra effort and only an extra grand or so in cost i could have built a bigger CC unit instead with this taller block and known that surge wouldnt be an issue.

 

Nice carpet, Chip!

 

That was what i meant Chip, limit boost versus rpm.

 

arr I see!

I posed the question in a "how much power do you really need in a mini" kind of way!

I'm sure it will still deliver the goods!

Alex

 

Its not my house, these arent my blocks, my friend just sent me these pictures to piss me off cause he was right all along

 

hmmm its not Rich's


so you have other friends???

 

On a fairly basic spec YB this turbo is happy to have 22psi rising to 28psi at the top end without any problems at all with surge (based on dougs current setup) thats enough for comfortabley over 500bhp on my engine at 8000rpm+

So its easily going to exceed the amount of power i wanted from it, so yeah im sure you are right about delivering the goods still, just annoying it could have been even better so easily!

 

the question is can i find another 1500 QUID

as i have not brought the crank yet

 

I know where 1500 quid of budget can come from

 

2 places and they both begin with c

 

But dont forget you would need longer rods too.

I dont think for what you are doing with yours it would really be needed

 

no i guess i can think of somewhere to much better spend 1500 pound

 

You wouldn't have got the bonnet shut anyways Chip
HTH

 

Ive got to make the bonnet and front wings longer anyway bernie so taller too isnt too much of a problem
