Hi Nick it's Christian, how are you?
I've opened this thread because I'm thinking to anticipate my engine build, but I need to find out a few things before I start buying the parts.
As you know, I'm thinking to bore my engine, and my first question is: TTR sells the Wiseco 88mm for the LNF. I was thinking to get the Darton sleeves and bore them to fit the 88mm pistons, but I've seen that OTTP also sells the Darton sleeves for the 2.2 engine, which (if I'm not mistaking) has the 88mm pistons. Would the sleeves for the 2.2 fit the 2.0 LNF block? Because if they do, I will save a lot of money by not having to bore the 86mm Darton sleeves.
Second question: I will buy the head/cam combo from zzp with the Supertech valve springs and retainers. TTR sells the Supertech .5mm oversized inconel valves, which I really want. Since the head/cam combo a better performing camshaft (I think, but I could be wrong, by opening the valves more), would I run into any problems with the .5mm oversized valves, such as the valves touching the pistons?
Third (and last) question: as you know, I'm not happy with the spooling time of my turbo. By putting wider pistons, oversized valves, ported head, better performing camshafts (and I'm also thinking to buy the Autowerks intake manifold from whyyoumadson, which it should give a bigger fuel flow), would I get an earlier spooling time?
Thank you
Christian

 

My bad. I just realized that the 2.2 also has a 86mm bore

 

i dont think you need sleeves until your pushing past 550... pistons and rods yes.

 

You will probably run into drive train issues before blowing the sleeves. Saving money for a trans upgrade would be wise imo.

 

Stage 2 tranny with 4.45 gear ratio already on the list, along with 2.1 gridled block with wisecos, carrillos, zzp neutral balance shaft, ATI SFI turbo balancer and head/cam combo. So the Dartons are off the list. The only doubt is about the valves. Stock? Supertech inconel factory size or .5mm oversized? If I get this doubt solved, I make up my mind about the all build.

 

run the gm trans spacer and put a F23 in it with LSD

 

Dude I haven't seen nick on here forever. Lol ... Email him. You may or may not get a response idunno
