2g 6bolt swap

[tsc1020]

I am working on a 6 bolt swap 2g. I'm building a motor that will be including Weisco standard forged 9:1 compression (Idk if I should do standard bore or .20 over?), manley H beam rods, ACL bearings, arp mains and head studs, Stock crank, mitsu Oem headgasket, Crower 272 cams, Crower Ti springs and retainers, the rest of the head is stock.

Turbo setup: Precision GT3582r, Peak Boost fmic, 2.5 inch IC pipes, Tial 38mm wastegate, greddy rz BOV

Fuel system: precision 1200cc, walbro 255, greddy fuel pressure regulator.

Tuning Ecmlink v3

Im asking how much hp will the motor support, and how much will my mods support. I also want people to correct me if im making a mistake with some of my mods. Thanks

I would ditch the greddy BOV and get a Tial!!!!! You dont need to stick a stock head gasket on a built motor, i would go with a MLS head gasket for sure!!!! Iwould also change to a areomotive a1000 fuel pressure regulator

I've heard a lot of bad things about cometic head gaskets, one blew on my also. But Ive heard good things from the Oem mitsu MLS head gasket i think its 4 layer I believe

then you need to put MLS in your first post, because ppl are going to think your talking about the stock graphite head gasket, yes oem evo3 headgaskets are the shit!!!!

Yeah I wouldn't put a stock HG on it . I'm aiming for 5-600whp till I get a built tranny. After I hope to get to 650-700whp. shouldn't I do standard bore just incase if somthing happens to the motor?

How much hp, there is a official thread on this somewhere on here.

 

[POS_Tsi]

In my opinion You should go slightly bigger on the injectors aka ID2000 and a dual walbro and run a 93 octane safe tune and a pretty crazy e85 tune! If e85 is avalible to you that is.

But your set-up as is sounds pretty killer. Congrats and good luck on the build I cant wait to see it finished.

and thumbs up to the TiAL BOV

 

[tsc1020]

Yes e85 is available. Thats what I ran in my 1g. I always wanted to know how much can you get out of a single walbro and lets say 1500cc injectors. Because the hanger for the duals will cost me

 

[tsc1020]

K1 tech rods, eagle H-beam rods, or manley H-beam rods? Which one is good for the most power?

 

[macks96boltdsm]

ive always noticed that the 255 walbro usually loses hp on the dyno around 500 hp so id say you be maxing out that single 255 but that just from what ive seen in my experiance only

 

[BogusSVO]

It dosnt matter what you want to do the block as far as std or .020 over. The block will let you know what it needs when it is inspected and measured.

ringwear, taper will let you know what needs to happen.

Also with the MLS, both the head and block will need to be milled to the proper finish.

I would also recomend that you have the entire rotating assembly balanced

This sounds like a killer build. I am currently seeking the same horsepower and it sounds like were in the same boat, to an extent. I am looking for 500-600whp for now and I did Manly H-beams with JE 8.5-1 pistons .020 over and a complete built valve train. I will like the option to go more later but have the motor built for it.
Dual Walbros sound very desirable with a -8an feed line and -6an return.
Definitely balance the motor for about 1k more RPM than you will be revving (balance for 10k if redline is at 9k) and the more you have to give your machinist to balance, the better (clutch, dampener, balance shafts if not eliminated, whole rotating assembly).
Sounds like you have everything so far tho, maybe port and polish and 5 angle valvejob?

 

[ed1380]

balance shafts. really? since when do the balance shafts affect the balance of the rotating assembly.
They're improperly called balance shafts. Their official name is silence shafts. Their job is to counter vibrations that normally occur in 4 cyl motors, nothing with the balance.

I would ditch the crower cams and go with HKS or Kelfords.

K1 tech rods, eagle H-beam rods, or manley H-beam rods? Which one is good for the most power?

^can anybody answer this question?

and any of you guys running on a SAFC on E85 or did all of you switch to ECMlink

Eagle and Manly H-beams are pretty much the same. I haven't heard anything about the K1's, but they are lighter which means they are probably weaker.

There has been so much different opinions/facts on the manley and eagles. How much can they handle ?
