Well the easiest way to remedy that issue is to delete the CAS and go to a hall effect sensor on the front of the head, of course your tuning software will have to have the capabilities of reading it's output.

[brndck]

I still don't see how the CAS is a problem. mine has plenty of room, and I can even remove/install the cas with the engine in the car. (on s13, mind you)

That cover your talkin bout is the cas block off they sell im talking p12 sensor cover look it up. Never seen such a product from Mazworx; btw you work for them bro?

Thanks for advice.
Today I installed my old stock mounts and BINGO!



Now I'm going to buy drift freaq's mounts. IIRC, they lower engine a bit more.

[rbs14kouki]

Im in the process of instaling my p12 cams in my p11 head .

Im looking for feedback or guidence on the head shim clearence ... im looking for specs to comfirm what i have and maybe a procedure if anyone could help

Here are the specs that i found (p11 / p12 and n1)

Taarks has an insanely easy and affordable option for the Hall effect sensor. No machinig required. I have it installed on my car and it works great with haltech.

It's a pretty slick setup too. I probably would've went that route had they had theirs available at the time. All bolt on, utilizing a freeze plug in the front of the head, I dig!

How's the car running Dave?

Running well. Need to finally get it to the dyno. I'm planning to just stop tuning once I 500whp and then back it down to 450whp. Even on just 15lbs. It's a lot of fun. I'm on the fence whether I want to swap the final drive to something lower, or stick with the q45 stock ratio and have a 2nd gear that doesn't end till a little over 80mph.

How's your car doing? I'm honestly thinking I'll sell in the spring and move on to a C6GS.

[TEALSQUEAL]

Finally got mine onto the rollers hoping to get the boost up and some numbers. Was at 374whp/350tq at 6800rpm and got spark blow out at 22lbs up high. We adjusted the gap and the dwell. Got a few hundred more rpm out of it and then it was just the LS1 could not keep up. I'm going to drop the boost to 19psi and leave it until I get haltech LSX coils. Still not bad torque or hp for the setup at that low of rpm.

[TheRealSy90]

That's crazy, I thought LS coils were the end all.
I know of sr20det's with stock coilpacks making more than that, even fwd sr20de-t's that don't have coil on plug can make more power on the stock ignition setup.

From my research and some of the local tuners that were doing national level 1000+hp cars it all points to the ls1 coils laying down. We gapped down the plugs, increased timing, and drop the dwell to 3.8 (ls1 coils die at 4.0). It got us another 5-600rpm. The coils to get are the haltech lsx coils are where it's at if you want a solid ignition.

[TEALSQUEAL]

Pulled a set of ls2 truck coils from an escalade. Remaking brackets and then should be ready to rock again. Triple the output of ls1 coils.

[TheRealSy90]

Have you looked into the Audi R8 coils.

[LuckyX2]

IGN-1A coils are the best. No argument.

That's what I switched to after getting blow-out with LS2 truck coils.

[TEALSQUEAL]

Money is what has me trying the ls2 truck coils. I sourced the set I have myself and at a price I couldn't pass up. I'm planning to get my car where I want it after all the years of building it, and sell it in the spring. I want a c6 grand sport.

[LuckyX2]

True, can't beat the value of the truck coils.

Just don't dwell them over 4ms or so, they'll auto fire early and make you detonate.

[TEALSQUEAL]

Yeah the farthest I take lsx coils is 3.8

[rbs14kouki]

We run some honda k20 coils on the race car .... fastess super street sr20 powered s13 in the world .... 8.23 @ 176mph

35+psi and no trouble with spark

[rbs14kouki]

Does any body have dyno spec of a sr20vet with a efr7670 ... i realy dont trust my pte5858 . Affraid its gona seft destruct like the last 3 pte we installed on customers car

Debating efr7670 , gtx3576r , s200sxe and efr7163(the 7163 is in last place simply cause i dont like the 2inch inlet on it)

It need's to be vband housing and so far the only one i cant find is the s200sxe

Im looking for +-500whp and its a drifts car .

Sr20vet specs

86.5 cp pistons (8.5:1)
Manley rods
P12 cams with custom high lob lock pins
E85 fuel


Feedback of poeple who runs them would be appreciated

Hey guys,

I was wondering what turbo manifold can be used on the P12 head? Is it the same as the DET but you have to slot some holes?

[insa]

Double post, read intake manifold...

Yes, some DET manifolds can be reused for a VE head, if the flange of the manifold has enough meat for slotting.

You can also have one made from the usual companies... i.e. Full Race will make a you VE specific one, if you ask them to (without additional charge).

[Yellow4g63]

No way the det intake flange will work. The port size is just too different. Also Gato racing has a intake manifold for the fwd or rwd ve. I have one for my fwd ve

[jr_ss]

I think he was referring to the exhaust side of the head.

[vipergtsr1000hp]

Just found out that the exhaust flanges are the same and the holes need to be slotted slightly. I am confused though on the oil pump/pulley/spacer issue. I am planning on running a P12 oil pump (apparently stronger). If I buy this collar http://www.taarks.com/product_p/nis-oilcollar-p11.htm will I need to buy the collar spacer. And if I have this correct, you must always shave 5 mm from the back of the crank pulley?

If you run a det oil pump spacer your gona need a spacer

If you swap out for the ve oil pump spacer (the one in your link) in your det engine no need to run a spacer ....

I did check the difference when my botton end was getting built... its pretty much same height

i chose to use the ve one just to simplafy the set-up .

[rbs14kouki]

If you keep the det spacer and run a ve pump without a mazworx shim , you will crank the housing of the pump like this

My SR20VET is soo close. I'm just awaiting a 82.5mm throttle body from RMR, my ebay one i bought was leaking bad out the Shafts on the sides (tps/Throttle body).

I have a few questions.

The front of the valve cover hits the hood pretty hard, what motor mounts is everyone running to space the engine down a little bit?

Also is there any other throttle bodies available other than RMR 82.5mm. I can't seem to find anything else and a stock q45 throttle body won't work because it is too long. I need a throttle body about 2" long.

I can't wait to rail this setup!!




I hope to do about 500whp then tune it down to 450whp.

I plan to run pump gas, and around 15-20psi. Any guesses on what she will do around that, i'm super anxious to get her on the dyno.

I have Nismo engine mounts, circa 06'.

You should be around 500whp. I made 485 on pump without water/meth. I don't think you'll need that for under 500whp. There are some slight differences between our setups, N1's and static comp ratios. You have 9:1 VE CPs and I run 8.5:1 DET JEs. However, I have a higher static comp ratio because of this difference. I also ran P11 cams, which will be swapped out to N1's after the new year.
