Thread: With regards to Turbo VE's

Coheed just for advice, use a good H/G, I would pick Cosworth for your app or OEM.

I always use the 20v gasket from Greg V. This thing has seen over 25psi of boost and never had ANY issues and I am using the ARP head studs.

Yeah that works better than a Cometic anyday....GL with the build.

great to see you are hoping on the i hate ARP wagon! i run them with no issues

There is no reason for me to believe that the studs are a source of issues, because I have run them in my car for the last year and a half and never had any signs of leakage. I have had a few runs on that car with boost spiking at 30psi on the freeway and I have not had a single issue. Every STOCK headgasket I have used always looks perfect when removed.

If it ain't broke I won't fix it.

^ exactly, too many factors to sit there and degrade the name of ARP without being 100% i always believed that, like i said i too am running them without a hitch, so i say like you say if its not broke dont fix it

Properly lengthed studs will be better than bolts since tensile strength will be better but more of a safety and reliable factor when pushing the motor to a great degree. Your choice of arp studs should hold up unless you plan to keep pushing 28+ psi at long intervals. Since they do not bottom out it is also a concern but your approach of " if it ain't broke dont fix it" is logical. I have used oem bolts and arp studs but have changed since those apps will not suffice for me.

I just got a steal, my buddy is upgrading and sold his intercooler to my other friend for $350. HE decided to go with a different setup and sold that same intercooler to me today for $100. Maybe the bigger intercooler will help as the core on my old one was like 16x8x2.5 and rated for like 300hp. This one is HUGE and has been proven to make over 550awhp on my buddies celica all trac.

The core is still 3" bar and plate. Est dimensions are 24x12x3. Def good for what I want to do with it. All for $100. Wow. It's even in almost perfect shape. very few bent fins etc.

awsome, good deal on that intercooler! what size ic piping are you going with ? 2.5?

yes sir, also I found this out and it may be very useful for those venturing into the VET projects themselves.

The 60* overlap is with the 16ve intake cam centerline at 100*ATDC and the 20ve exhaust cam centerline at 114*BTDC.

While I'm at it, More VE camshaft overlap:
SR20VET - 13*
SR20VE - 48*
SR20VE 20V - 57*
SR16VE - 70*
SR16VE - N1 (v1?) - 78*

Thanks to FastNX ,92nx2k and hpro123 for the information

Now this info is from the other forum. Here's what I found out for myself...

Honda cams. B18C cams
intake 230 duration 10.7 mm lift
exhaust 227 and 9.4 mm lift
17 degrees overlap

Type R cams
intake 240 and 11.5 mm lift
exhaust 235 and 10.5 mm lift
28 degrees overlap
