Arp Studs for GSR Head?

[Colt Gti T]

Hi, I must decide what to do :
Use 4g63 M12 studs (reboring block from M10 to M12 is posible but.....)
or start looking for some other Arp studs (toyota?) M10/1.25

Now on my desk I have M12 new set of Studs for 6bolt 4g63 , have place where they are able to rebore block but still in my head is qestion is it a good option?


In future i whant to install H-beam Conrods and forged pistons. I need good bolts for metal gasket.

In poland hardo to find something form 4g93 ( 4g63 is most popular engine) and of course
everything for honda engines is on shelves.

And maybe using the same post:

What you recommend:

Buy serial GSR 92-95 ECU and bild wiring for it or
use my own 4g93 Ecu and make new maps on Piggy back (i'm thinking about EcuMaster3 )

Its spec for EcuMaster 3 (my translation because its polish stuff)

* 4 Maps 16x16 (fuell map, 2 maps PWM, ,ignition map)

* 8 Correction maps 16x1,

* 2 independent, swichable map combination,

* 2x modified analog Out

* 4 x analog In

* Build in DataFlash (Data loging with out PC)

* Ability to modyficate MAF signal (17Hz-4kHz),

* Modyfication of ignition signal using sensores: Hall, optical and modyfication signals for Ignition modules (single ended & differential),

* Many Ignition modules type compatybility: 60-2, 36-2, 36-1, Multitooth, Ignition Modules,

* Handling Turbo BOV (???),

* Handling 4 HighResistant Iniectors "full group"

* Out ON/OFF (parametrical)
* Automatic conversion from MAP to MAF using lerning moule

* Start procedure,

* Onwheel Dyno,

* Ability to convert analog sensor to show parameters like we whant MAP in PSi, Lambda like AFR, etc.),
* USB port for PC

3SGTE toyotas.. fit perfectly but hang maybe 3-4mm above what normal head bolts do but it doesnt get in the way...

I've redrilled mine to suit Evo 11mm items.

too much headache to do that.. just drop in the 3SGTE.. perfect drop in fit!!!

Ok.
Now something is going...
How you redrilled for M11? How it works?
Work and money with redrilling block are the same as looking for new ARP for toyota:
can buy them in US for 130$ but 60$ is for shiping to poland (that makes almost 600PLN)
for my ARP for 4g63 I've payed 200PLN and redriling block is cost of 300PLN and will have stronger studs....
One way its skary to rebore block but, other wholes will be stronger than M10 and they will take more torque....

Thanks for option with this loom but with out ecu its nothing new

My Loom its in perfect shape and its almost the same like GSR - but lif i buy GSR ecu im "grounded with serial non tunable ecu" Youre piggy back its maybe better - but in poland nobody will tune me it (they dont now it and i dont whant be a laboratory rat for them )

We use SMT6-7 Ecumaster 2-3
All kinds of AEM, gredy , Haltech and more other stand alone ECU's but they arent cheap (cost in poland its above 4000PLN what gives like 1800$) Money like this i will spend on forged Pistons and conrods

Welcome Colt GTi T good to see some Mitsu freaks from around the globe on here

smts are good.. i remember a mate had one a long time ago.
one question will would u redrill the motor when there is something that will fit? what happens if you mess up?

if it was me i would just go a drop in replacement instead of messing around making something try to work.
