Now that I'm finally getting around to finishing all the maintenance stuff on this car I'm slowly starting to get into my build and want to know if Iím going in the right direction. plans for the build is dr750s, dr stage 3 heads/ street cams and since I currently have a 2 bolt block and have to switch it up anyway rays 3.5L stroker.
I will be running meth and 94/93 pump gas and tuning it all on an AEM.
I know a lot of people have said the TD04's will choke off the 3.5 and that I can probably reach the HP goals a lot easier on bigger turbos etc etc. but thatís not what I want out of this car.
I will be building this car over the next 2-3 years ish to drive in the summers and on the track. I live in an area were DD'ing my car means hairpin turns, single lane traffic with short tiny passing lanes and 3000+ft elevation changes, where laggy cars just aren't that much fun. This is why I decided to see how far I would be able to take the TD04's
I guess Iím mostly looking for some guidance from matt and ray and others who have experience with the 750's to see if this is the right path to take to draw the most out of these turbo's
Thank You in advance for any help you guys can give me.
3.0L, MHI 19Ts, AEM EMS, and every bolt on you can think of. 94 oct./Meth.
RMRwe have no idea what we're doing.
No. There are quite a few guys hitting 600awhp with dr750s but either running with method or e85. Even with cams and heads and an extra 500cc I doubt you will get the extra 100hp even with better fuel. With straight pump i say no way. I hope I'm wrong cus it would be awesome. Hopefully ray can chime in.
I assume your talking about pump gas and meth?. Its been my experience that with dr750s on 93/meth that 24-25psi is max boost you could get away without getting into knock. I dont personally run 25psi unless I've got a little race gas mixed in just because I want my motor to last. I guess what you need is to ride in a dr750 car at 25 psi and see that it is probably more than enough power for your streetcar.

I'll be building a friends 3.5L DR750 car in a few months, so i will have some real world info/results for you. There will be a thread about it of course when the build actually starts.
Wont be anywhere near 700awhp we dont think, but like you the owner cares little for big top end freeway pulls and likes the big block V8 engine feel. So the 3.5L with the 750's is as good as thats gonna get.
Also the benefit of the 3.5L is the crank is strong enough to run years at 600+ wheel torque where the stocker is questionable long term at that power output.
We kinda figure the car will be a around 6-650 wheel torque and around mid 500's hp at the wheels on 93. Not messing with meth anymore since getting greedy with it cost 4 DR750's and 2 engines. Race gas = cheaper than the potential foul up with meth.
Now if you want to run meth and are okay with the risk, its damn near another 100hp on pump for 450 bucks. So...its awesome in that regard.
Silverstone Metallic 94 R2 FD.
Sold: Black 99 VR4 and two Pearl White 93 VR4's.
When my motor goes south I'm going with a 3.5 as well. You may as well go 6G74 if you are going to build anything IMO. It isn't hard to fit the stock manifolds to one anyway and if it ever blows up it is cheaper to fix than the crankwork necessary to fit the 3.0 block.
matt's stroker was a beast with the DR750s, if you read his old dyno posts you can see it is not a mis-match at all. Like any reasonably sized turbos you aren't going to have any power in the 2000-2500 range and the extra displacement is going to make this area feel a lot better.
It is really nothing you even notice unless you are saying lugging in 2nd gear at a point where it seems stupid to downshift to 1st. That's the only reason I want the bigger engine really.
