Okay, thank you for your opinions.

I will also make a video as soon as the car is running again. (waiting for new Turbo)
The valve setting game is starting to get quite expensive. Gone through 3 sets of shims now and one shim is like 5Euros here.

Regards,
Dennis

update
I got to drive the car around and it need some cam adjustment curranty it is a dog on low end above 4K it screams i have a bad wastegate Diaphragm so that could be part of the issue.

So if i jump on it it is a dog until 3800-4K then it comes on and i am running 1 Bar and shifts nice and hard and i have run it up to 6K pulls all the way not to sure how far it will pull up to running out of room and speed is up there as well.

i would like to get more low end on this so i will be making some cam timing adjustment to see if it helps.

So This is my setup

530 head ported oversized exhaust KLR T2 Camshaft Yoshi Fab adjustable cam gear

91 exhaust manifold ported

Chinese Gtx35 BB turbo supposed to be .68 hot size need to re-check it is a big turbo my Buddy runs runs these on RB25 and they work very well.

Tial F38 38mm gate knock off bad diaphragm real one on order
Stock AW71 with acumulator mods

Chipped ECU could be part of issue I Have Megasquirt to swap in the future

RS 500 intercooler modded

3" exhaust

I will be doing more cam verification and adjustment today to see what i can do.

Certainly verify the cam timing; but conversationally, I am not at all surprised that a GT35 based setup doesn't start to party until 3800rpm.

Especially if the wastegate isn't fully shut. Bleeding off the boost before XXX rpm is going to make it feel slower than N/A. Had that issue on my old 940T - WG would hang open slightly and it sounded horrible and didn't boost for **** until about 4k.

Yes this describes my car curranty SAF under 4K

i pulled the Valve cover and look at the cam it seams not far off compared to the stock head i pulled off.

so i am looking at basic items now to see what i am missing.

rear mounted Dizzy could this be off causing issue this was removed and installed on this head is it possible that the drive slot was cut wrong? i will look up correct settings for this

A KG2T cam has 300 degrees of duration. So once you sort out the engine of any issues. You will then enjoy a 3500-7500 rpm powerband.
This is why the rule of thumb is buy the mildest cam that will accomplish what you are looking for. With some adjustment you may get the powerband down to 3000 to 7000 but it's a high duration cam that is made for high rpm performance. Use it in the manner it was designed and you'll be happy.

Not trying to give you a hard time. Just wanted to make sure you knew what you selected. For example a Stage one enem cam has 256 duration and is a 2k to 6k rpm powerband. A stage 2/3 V16 turbo cam has 268
duration and the powerband is 2500-6500rpm. The 300 duration enem cams are upto stage 4 which is a pretty high rpm powerband. 3500-7500 is typical. http://www.turbobricks.com/resources...ontent=camspec

Here is the KG specs

I would agree the cam would be an issue but i didn't think i went that big on the cam
this is the cam i ordered and the box was marked as such.

KLR T2 Suitable for engines with a slightly larger Turbos and increased charge pressure, provides substantial power increase to be such a nice camshaft.
Has good idle and low speed.

The camshafts are ground on new substances (we do not need any old camshaft in exchange)

Dur at driving game 280 degrees
Cam lift 11.3mm
Nock angle 112 degrees
TDC lift about 2.5mm
Valve play 0.35mm
Distributor track on camshaft: Yes
Needed lasch cap: Yes, 2.5mm thick is recommended

TDC lift is indicated by valve play and is set as follows.
Set the engine with the piston in the top position (exhaust gas is closing and suction is about to open).
The intake valve must then open the stated value. The value can be adjusted slightly during test driving for best results. Adjustable cam drive facilitates this optimization

Tip: Make sure that it does not break in the camshaft during assembly / disassembly, then the axial bearing on the rear edge can break, applies to all sharper camshafts

https://shop.klracing.se/sv/artiklar...-klr-t2-2.html


still working on the issues ordered new .63 turbine housing and new wastegate.

verified engine and cam is lined up correctly. Now i will go through everything to make sure it is correct this weekend with all new parts installed.

A KL racing cam is a different company thann a KG2T. KL racing and KGtrimning respectively. 280 degrees is still a high rpm cam but should be a bit more tame than the 300 degree duration of the KG2T. For example I am going to be using a turbo version enam V16 which is 268 degrees. With that duration it is already considered a 2500-6500 rpm powerband. So I wouldnt expect a 280 degree cam to come on before 3000rpm.

The KG2T is not 300° of duration when measured at the same lift as KL Racing's camshaft being measured as 280°, I expect. The KG2T is not a racing camshaft, either.
