O.K guys here is my situation. I have a 98 a4 with a 3700 stall, longtubes, lid, cutout. Im getting a ls6 intake in a month orso. Anyways I am wanting the most power out of the 2 combos i have listed below. This is my dailydriver car but i race it like crazy at thestrip and street. I love the power of the t rex cam on stock heads. I was going to install a tr224 114 and pp stage 2 5.7's. but now i am debating on getting the trex. i will have it ls1 edit by a very good tuner. This is my daily driver and i ma looking for the most pwer.
will i have any pv clearance issues with thetrex? i have stock untouched 98 heads that have never been off teh car. thanks
does anyone kow ifthunder has a t rex kit yet? how much and what is included. thanks
i know they reccomend a 4000 + stall but mines is close to that and i am gong bigger this summer. thanks again

You mention PP stage 2's, then say you have stock untouched heads?? If the heads are STOCK, never been milled or valved, thent he T-rex will go. If you go with the patriots and the bigger valves, it will not fit.

id say go with the trex cam it put down really good power and as long as you dont swap heads in the near future youd be ok...as far as daily driving im sure it can be done but id think you wouldnt like it much unless you dont mind a pretty high idle w/your a4...otherwise why not see what tsp & patriot can do for you w/those S2 heads/cam combo i know last month they were running everything you needed basically for $1500 and you could probably get their 231/237 cam and be happy with that even as a daily driver and SHOULD be able to make the same power...after all is said and done with that cam your looking at close to $800-900 between the cam, springs, retainers & PR's.

good luck

how high of an idle do youthink i would need? iam leaning towards thetrex cam and keeping stock heads. I wonder how much power I would make through my loose verter. how much track time would i gain switching to it from my stock cam

foff667

iTrader: (2)

id assume with all the bolt ons you could still make well over 400 to the wheels with your vert...track time kinda depends on your supporting mods & traction...you'll definitly need headers to take full advantage of pretty much any cam but id assume you could add probably 7-10mph in the 1/4

as far as idle goes i know with the tsp cam you need about a 900-1000 rpm idle to keep it in check with an auto im not sure about the thunder cam but id assume somewhere around 1200

I think you will be able to set the idle at around 800 with it tuned really good for the street. 2001zz with a 4400 and slicks you car "should" see a high 10.

W/O too many people running the T rex yet , i would not put it in a A4 daily driver. Sounds like trouble to me. IMO

what kind of trouble you think i would see

I have the TR230 now (Trex/springs coming next week) in my A4 and it bucks in traffic (not a daily driver though). I'm running 3.23 gears and an SS4000 stall. You are gonna like the trex for a daily driver for about a week, then your gonna wish you went with something smaller IMO. Forget about 800 RPM idle on an A4 with a Trex, you'll have surging issues. I've got 3.73's going in the car, and I would suggest you do the same if you get the trex and keep your stall..Good luck!

I agree. Thats why i said it sounds like trouble. I think it will get old fast. Wait till someone else trys it first

For DD, go with H/C on an A4.
Stg II heads with a 224 or even a 228 on 114.

Honestly, they will put out very close to the same power ...

TRex Pro = Lots of power, small price
TRex Pro = Going to sound BADASS.
TRex Con = Relatively little PtV clearance.
TRex Con = Probably going to be a PITA for an A4 daily driver.

H/C Pro = much better drivability (you could probably even go with a little bigger cam)
H/C Pro = going to be nicer on the springs and drivetrain overall
H/C Con = Price, price price
H/C Con = Not going to give you that nice lope the TRex will (it could also be a pro if you don't like the lope, I guess)

I wouldn't do it myself and I am a A4 with 373 gears 4200 stall. I only drive my car about 50 miles per week, but I know that this cam would suck as a daily driver.
It is bigger then the cam I have in my 410ci motor.
My suggestion would be a nice set of heads, and a 227/230 TR cam. You will see very little power difference and it will be much much better for driving around. I believe you would be happier this way.
Going from a stock cam to the trex is like buying a cruise ship as your first boat. Its a very big step.
Good luck if you go TRex,

i always did like curise ships, then again im a m6 so im not to worried about it. our idle gets set to 900 with the trex. with 3.73 and a 4200 stall with proper tuning the trex will work fine. plus it saves lots of money. then in a few months if you get tired of it, you can save up enough money for a flycut and better heads. then you will have some nice numbers. thats my plans, except ill get new pistons with valve reliefs instead of a flycut. either way, i think you will be happy.
imo
if you are in nonstop traffic every day. go smaller on the cam
if you daily drive mostly interstate, go trex.

my vote is TEA 5.3 heads and a FM4 114 cam. just do some research on FMS cams and now much usable power they put down and there relative mild idle quality and TEA heads speak for themselves. its almost guarenteed you'll put more power under the curve with the TEA/FMS combo then you will am only with the Trex. and at the end of the day thats all that really counts.

2001zz

i dont mind a little bucking i guess. so i wont have a pv issues on my stock 98 heads?
what will my idle have to set at. anyone know how much the kit is.

SMOKIN01TA

iTrader: (10)

idle will be right at 1000 or maby 1100, if you have a good stall, you should be good at 1000. the kit price is dependent upon which springs you go with. i went with the crane duals, seats, seals, pushrods, gaskets, tit retainers and cam for around 850-900 bucks. the comp duals are like another 100 to 150 bucks more for the kit i think.

Pricing is on the webpage for the TReX. You will need one of the following for the TReX:

LS1 Cam package price w/ Comp 26921-kit springs, cam, pushrods, and gaskets - $1024.99

LS1 cam package price w/ Crane springs, ti rets, seats, VS seals, pushrods and gaskets - $849.99

We have used the TR230 in quite a few daily driver A4s and the customers are more than happy. Again, the key is the tuning! With gears/converter/tuning, the TReX can be used in an A4 car that sees quite a bit of street driving. We will installing this cam in a similar setup in the next couple weeks. I'll keep everyone informed on how it turns out.

thanks for all the replies, I think I am going to try the t-rex out. guys i have pretty muchall the boltons besides the pulley and ls6intake whichwill come in a few months. I know i wont gain as muh because i am lacking those, but i wonder how much power I wil see to the wheels as this thing sits? i currently run 12.5 in the 1/4 i wonder how much this will help? thanks
