Hi Everybody

 

Well the order has gone in for the parts and they should all be here by April

apart from the head gaskets , i am not sure what size ( thickness to go for )

 

here is the list of the spec i have bought

 

PE 1420 Turbo Charger Kit

Wiseco 87.5mm Pistons

Nismo 555cc injectors (pre-1994)

Injector O-ring (top)

Injector O-ring (bottom)

bypass water hose

Engine Gasket Kit (excl. stock head gasket)

Rubber Half-moon gaskets (left out of above kit)

Turbo Inlet Gasket Kit

Cometic Head Gasket (88mm) *****

Eagle Rods

ARP VG30 Head Stud Kit

MS Manifolds

Border Front mount Intercooler

Profec b boost controller

 

what would the techies out there advise ?? i am swayed towards the 1.524

+0.060" i am loooking for a good tourque figure over outright power so i aim for about 400 rwhp , at the moment i will be using a DTA chip to suit the above but i will be upgrading to a stand alone ECU in the near future so mapping , problems with Det should not be much of an issue

 

thanks Guys

If you get the heads skimmed and you should by the way! go for .051" thickness as this will compensate for the average amount of material removed from the head face and not affect your compression ratio(as long as your using stock compression pistons).

Stick with stock compression IMO (and compensate for any head skimmed as Jimmer mentioned) unless your looking to run silly boost levels (2 bar / 25psi+)

 

Lowering the compression will allow you to run high boost levels with reduced chance of detonation but at the sacrifice of response and low rpm power/torque.

Always sold the 1.2mm gaskets mate. the 1.4mm is too thick really for what yer doing.

thanks guys much appreciated the advice , i will get on to Danny and advise the thickness required

My heads have been skimmed!

Ive got eagle rods and slight over bore wiseco pistons aswell and was advised to go for the 1.2mm cometic gasket is that right?

Yes.

I have the 1.2 with no problems

opps i ment 1mm

:(

The 1mm gasket is stock thickness. If you had the heads skimmed then the overal compression will have increased if you're using a 1mm gasket. Not detrimental to performance though.

Thanx for your reply Dta

But could it cause anyother problems to my engine?
